The precautions of industrial main board

Industrial control main board is used in industrial settings, the main board is used by industrial computers. According to the demand, main board can adapt to a wide range of temperature environments, it can adapt to harsh environments and work for a long time under high load, etc.. So what matters should be noted in the use of industrial control main board? Here's a look at the following.

Please plug and unplug components under power failure conditions. Before connecting the power connector to the main board, please you confirm that the power is off to avoid instantaneous power shocks that cause damage to sensitive components.

In addition, please confirm that there is no pin or other short circuit caused by the transportation process, Note: modern electronic products are very sensitive to static electricity, take the main board before, please wear a static hand ring or static gloves to conduct your body static electricity away.

 You place the main board in the static table mat or static bag and confirm the correct jumper configuration of the main board to avoid damage to the product caused by misuse.

Industrial control main board can simultaneously support CRT and 18bit color TFTLCD display output without affecting each other, you can use when connected to use at the same time. Accessories have CRT adapter cable, one end of the adapter cable to the main board CN4, the other end to the CRT display, CRT power can be correctly displayed.

How should I troubleshoot embedded motherboards?

 Embedded motherboard is embedded in the device to do control, data processing using the CPU board. Simply put is the brain of the device, embedded into the device will have a relatively strict requirements on the volume, power consumption, so that embedded devices will usually have size, high integration, low power consumption and other characteristics. Regardless of any equipment in the use of the process of inevitable failure. Therefore, how to troubleshoot the embedded motherboard problem?

Firstly, checking the power supply and the components

The role of the power supply is very important, insufficient power, the output voltage and current abnormalities will cause a variety of failures. Therefore, the power supply problem should be ruled out first, and then consider other components.

Secondly, checking the external equipment first, then the main unit

Faults caused by external devices are usually easier to find and eliminate. You can check the various connections of external devices and their own working conditions according to the system error message first; after excluding the causes of external devices, then consider the host computer.

Thirdly, checking the software and the hardware

Embedded motherboard failure, first to exclude the software reasons, and then consider the hardware reasons.

Fourthly, considering the simple failure and the complex failure

Hardware products are not perishable, so when encountering hardware failure, should start from the simplest reasons to check, for example, to determine whether the connection of various cables is normal, a variety of plug-in cards are poor contact, etc.. If the fault persists after inspection, then more complex faults in the mechanical part of the circuit or component can be considered.

When you encounter a fault problem, you need to investigate it step by step in order to find the problem and choose the right solution.

Why self-service terminals are popular with users

Self-service terminals have started to expand rapidly from the banking industry to other fields, and their applications have expanded to a number of industries and fields such as telecommunications, electricity, medical, aviation and retail. Below, we introduce the reasons why self-service terminals are loved by users:

Self-service terminal is a "24-hour self-service" as the design concept of intelligent equipment, self-service terminals are widely used to alleviate the problem of excessive traffic in the business hall and other industries, to make up for the shortage of the original industry business hours, but also to avoid customers in the business hall for the relevant business troubles. Self-service terminals bring easy, convenient and considerate self-service to customers.

In the financial industry customers can use self-service terminals for account enquiries, self-service transfers, statement printing, registration, self-service lost business; in the communications industry customers can enter their phone numbers through self-service terminals, self-service mobile phone stop (re)machine, bill enquiries and printing, bill payment, invoice printing, caller ID, GPRS and other basic services for opening and closing; you can also buy mobile phone cards The self-service terminal can also be used for the purchase of mobile phone cards, password recharge vouchers.

What are the disadvantages of a mini PC for a business?

Assuming you mean a USSF or smaller.

There are not many actually, which is why so many are used in business environments.

Others have mentioned the lack of expand ability - so you really need to know WHAT you need when you go out to buy one, as there is little or no scope to add anything afterwards.

If you want to upgrade the graphics, you will have to hope it works with an GPU.

In my mind, for pure business use, you have to carefully consider what CPU to go for; not just for longevity; but because the bigger cpus draw more power and create more heat, so the fans have to work hard to keep it going.

And the fans in these cases have to be small - and that means very noisy when their speed is raped up.

You CAN get small, efficient and quiet Noctua fans, but I don’t know of a system builder using them - they aren’t cheap - and retro fitting isn’t always possible.

There are many mini PCs coming in from China that are basically laptops with no screen, they tend to be a lot quieter, but remember the CPU inside are “m” versions, so are a computationally a lot less powerful than the desktop versions, and so may run out of steam in a couple of years, due to software bloat.

Pick the right one, and it will do the job you want for 10+ years; pick the wrong one and you will be looking to replace it in 2 years.

The type of panel pc touch screen

The distribution of the current advertising all in one pc is also varied, touch type is also emerge in endlessly, for many consumers to buy things, always first to know exactly what to buy types, panel pc, touch type variety, but many consumers are not clear, I should choose or design type. BVS is about panel pc those things for you today!

Now the most widely used and the most popular panel pc touch screen, there are more in the market, nothing more than infrared touch and capacitive touch. So how do we choose and distinguish between the two? Let's talk about capacitive touch first. First of all, it looks nice and smooth, supporting 2pm, 4pm, 6pm, 10pm and of course 20pm and more. This is related to the fact that our chip is what we call the processor, and the capacitance is in a G+G structure. The touch features are heat and press. Therefore, its price is relatively expensive, but its performance is also very stable. The optional range of capacitor is about 10 to 65 inches, so the selection range is not very large.

Next is infrared touch. Its touch mode is ten-point interactive induction, but the appearance is affected by the infrared touch frame, and there is a groove of the frame. Relative to the capacitance, the United States point of view is relatively close, and the infrared is the induction characteristics of the cross interaction, so it is susceptible to the impact of dust on the internal screen. This time need to be corrected to recover, so for infrared, dust and ash prevention is necessary, but the infrared relative capacitance price, is relatively moderate, the size of the choice of type is more. Basically covers capacitance selection, but also expands the selection range of more than 100 sizes.

Okay, so with those two common types of touch mentioned, let's talk about some of the rare or obsolete types of touch on the market.

Resistant touch, its advantage lies in its lightness. However, because the touch type is a positioning touch, it is easy to be affected by heat, resulting in touch failure. So relative to the market, even if it is cheap will be eliminated, you can refer to our earliest Nokia before the kind of mobile phone screen. Nano touch, nano structure is G+F type, function is realized through heat sensing and pressing, through the window structure to achieve induction, is the characteristics of its nano induction. However, for nano-touch, relatively not very stable, the price is also on the middle. And the most deadly is, once the panel pc touch screen appears to fail, basically represents the scrap, so it is one of the reasons that the market is rare. The last one is optical touch. Optical is an panel pc with light source modules installed at four corners and reflective strips attached to the frame to realize touch writing. However, as a type not the mainstream in the market, it is relatively rare in the market.

That's all BVS has to say about panel pc touch screen types. If you want to know more about our products, please pay attention to our website.

Application of all in one pc in intelligent express cabinet

With the rapid development of e-commerce, have you found it more and more convenient to get express? Before, we usually had to go to the express station to pick up the goods in person, but now we can go to the express cabinet to identify and pick up the goods. Therefore, in the demand of market environment, the development of intelligent express cabinet is undoubtedly the inevitable result, and it will be more popular in the future. Then, as the control center in the intelligent express cabinet, the all in one pc is bound to usher in another potential application market.

BVS's Android industrial tablet adopts the whole aluminum alloy body design, and the flat panel is seamless and fully closed design. It is not only rugged, but also uses capacitive touch mode, using ten-point touch technology. Therefore, the touch response is more sensitive, the sense of intelligent experience is higher, and the touch picking has zero delay without waiting. The built-in Android 5.1 operating system, strong software compatibility, support the secondary development of user APP software, meet the needs of intelligent express cabinet built-in software, support operator scanning code, face recognition and other ways to pick up. This way can not only improve the convenience, but also greatly improve the safety of the express. At the same time, it also supports ODM/OEM customization services, including appearance, screen, size, use environment, as well as RFID card, bar code card, ID card, face recognition and other additional features customization.

Last year's FengNest charging event, we can see that the application demand of intelligent express cabinet is still huge. In fact, in the development of intelligent express cabinet, not only Feng Chao, as early as 2017, China Post Holding Express Easy has officially entered the intelligent express cabinet industry. In 2018, Cainiao launched the intelligent cabinet of Cainiao Station. By 2019, JD will also launch its own delivery cabinets in major cities. As a professional touch-control display equipment touch-control strength manufacturer, BVS touch all in one pc, while maintaining focus on industrial intelligent automation applications, is also constantly actively expanding more application markets.

The application of POS system in cash register

I believe you can see POS machines in milk tea shops, hospitals, restaurants and hotels when you check out. It can be seen that POS machines are everywhere in our daily life. Today BVS will bring you together to discuss how POS system are applied to these places in the cashier.

With the development of the Internet, smart cash registers have become standard in restaurants. Large chain stores, small to milk tea shops, have been using cash registers for cash management. We can generally see that many cash registers in milk tea shops are set with double screens. For example, our 15.6 inch Windows 7 System POS machine has a double screen plastic shell. On the one hand, this all in one pc is convenient for shop assistants to order food, and on the other hand, it is convenient for customers to clearly see the price of milk tea they buy.

With the popularity of bank credit card, more and more patients choose to pay by credit card after coming to the hospital. Therefore, many hospitals collect fees through UnionPay POS machines to facilitate patients' checkout.

Now when customers are eating in the restaurant, they can scan the QR code on the desktop to enter the electronic menu and order food. After submitting the menu, the POS machine of the cashier will print out the menu automatically. This ordering process completely requires no human participation of customer service. This kind of self-service ordering system is not only efficient and fast, but also cost saving.

As I believe you all know, when we leave a hotel to check out, there will be an POS machine at the front desk. The general checkout process is to enter the customer's room number, scan the code and print the receipt.

The above is the application of POS system in some places. Thank you for reading!

The difference between solid state drives and mechanical hard drives in touch all-in-one machines

 

Do you know the difference between a solid state disk and a mechanical hard disk in an all-in-one touch computer? Today, BVS will take you to know about it.

1, the storage medium is not the same, the mechanical hard disk capacity is larger and the life is longer

The current capacity of SSDs is only 4TB, and SSDs for the same price are much smaller than the capacity of mechanical hard drives, which is now the advantage of mechanical hard drives over SSDs. In addition, SSD uses flash memory particles to store data. Even if SLC is selected, it only needs 100,000 times of read and write life. MLC with relatively low cost has 10,000 times of read and write life. And the price of cheaper TLC flash particle erasure times only 1000 dominated. Mechanical hard disks can read and write more times, and there is no need to worry about the shortened life caused by repeated erasing.

2. The different structures contribute to the many advantages of SSDs

Mechanical hard drives are disk-shaped, and the data is stored in sectors of the disk. Solid state drives, on the other hand, are made of flash memory particles (memory, MP3, USB, and other storage media), so they are lighter in weight. The absence of mechanical motors and fans also means that there is no noise, bump, shock, and vibration when they work. With flash, the seek time is almost zero, and the speed of continuing to write is faster than that of a mechanical hard disk, which is not the same as the speed of the disk's inner and outer ring partition.

The above is the difference between solid state disk and mechanical hard disk, the mechanical hard disk or solid state disk should be selected according to their own use. If you want to know more, please pay attention to our company website.

Touch query machine use common sense

Today BVS tells you about the use of touch query machine common sense.

1. The touch screen part of the Touch Query All-in-One Machine is glass products with sharp glass edges and corners. Gloves/finger gloves are required for assembly. Do not have too much impact on the touch screen when assembling.

2. In order to avoid the internal burnout of the touch screen, it should be avoided to display the same picture for a long time during use. Be sure to turn off the monitor if you're not using it.

3. Please be careful when moving and handling the touching inquiry machine. At the same time, we should do a good job in the work of shock proof, moisture proof, electricity proof, waterproof, pressure proof and collision proof. Do not open the back cover of the monitor under normal use. 

4. Please do not attach additional weights to the touch query all-in-one machine or bracket, because the bracket or wall parts are only designed to bear the weight of the touch query all-in-one machine itself. Please do not strongly collision, vibration screen, so as not to cause damage, short circuit or plate deformation.

5. In order to ensure the normal operation of the touch query all-in-one machine, in addition to ensuring the correct installation of the system software, pay attention not to install two or more kinds of touch screen drivers on one host, which will easily lead to the conflict of the system operation, so that the touch screen system can not be used normally.

The difference between liquid crystal touch infrared touch and capacitive touch

 

The LCD touch machine can be regarded as an information display, supporting the display equipment of machine to machine and human to machine interaction. Liquid crystal touch all-in-one machine is a set of advanced touch screen, industrial control, computer and other technologies as one of the equipment, we can use powerful functions to achieve information inquiry, fingerprint identification, scanning, reading information, printing and other services for the public equipment, as well as fingerprint attendance, card swiping, printing and other needs. The touch screen has multiple screens; Now liquid crystal touch all-in-one machine mainstream application has capacitive touch and infrared touch two kinds, BVS take you to understand these two kinds of screens.

Infrared touch technology has been very mature, touch sensitivity can also, plus the cost is not high, touch all-in-one machine has a lot of infrared. The disadvantage of infrared touch is that there are requirements for the application of the occasion, infrared touch is not suitable for the occasion of strong light, when there is direct sunlight on the touch surface above, the accuracy of the touch has a certain impact. Infrared touch is to analyze the position of the touch by blocking the infrared ray emitted by the infrared frame. As you can imagine, when there is dust, water droplets and other shielding will have an impact on the touch. Therefore, generally in the absence of strong light irradiation of indoor cleaning scene, choose to use infrared touch.

A capacitive touch screen can simply be viewed as a screen made up of four composite screens: the outer layer is a protective glass layer, followed by a conductive layer, the third is a non-conductive glass screen, and the innermost fourth is also a conductive layer. The innermost conductive layer is the shielding layer, which plays the role of shielding internal electrical signals. The middle conductive layer is the key part of the whole touch screen. There are direct leads at four corners or four edges, which are responsible for detecting the position of the touch points. Now with the gradual reduction of capacitor cost, as well as the larger and larger size of the capacitor, its high sensitivity, strong anti-interference ability, a wide range of use scenarios, small impact on the appearance of the machine and other advantages, capacitive touch at a fast speed to differentiate the market share of infrared touch.

Now the LCD touch machine technology and solutions have been mature; It can meet the application needs of different regions, different places and different users. To meet the needs of customers for intelligent society, provide life efficiency, and provide better conditions for the display and dissemination of information.

The above is about the difference between LCD touch all-in infrared touch and capacitive touch. If you have other questions, please pay attention to our company's website.
