Xiaobian’s visit found that when many cashiers use the supermarket cash register in peacetime, there will be some problems that they have never seen before, but they don’t know what to do. Next, I will tell you some tips.
1. Cash register performance determines the user base is different:
A mature enterprise will choose an industrial computer to improve stability, taking into account the unique stability of the industrial computer.
2. Cash register optimization processing:
On the industrial control main PCB board, the ground layer or signal layer is added, which can effectively reduce the signal interference, and is more conducive to the stable operation of the POS system which requires long-time uninterrupted operation, and the general PC motherboard does not. On the CPU side, the working environment of the cash register is very different from that of the desktop PC, so the CPU frequency can not be compared with the desktop PC. Although the frequency of the desktop processor is now higher than 3GHz, for the POS machine, the 433MHz central processing The performance is already sufficient. However, if you use 300 or less, it is really too low to be undoubted. The faster the processor, the more efficient it is, and the more convenient it is to satisfy data settlement. The power consumption of the processor is also quite remarkable. Generally speaking, it will not exceed 10W, and the generated heat is also small. Therefore, an active cooling fan is not required, and a simple passive heat sink is sufficient, which further simplifies the POS system. The structural design of the memory.
3. The dedicated interface is rich:
Since the industrial cash register needs to connect a lot of peripherals, it is more than the ordinary PC in the serial port.
4. Small board does not equal industrial control:
In recent years, due to the intensification of competition, some enterprises have used small PC boards to pretend to be industrial control boards, which makes a very big mistake. It is impossible to compare the board with small power consumption and the industrial control board.
