Reasons for faults in industrial computer circuit boards
1. Power supply issues: Poor power stability, voltage fluctuations, or overload may cause circuit board failures. Poor or damaged power cord connections may also cause the circuit board to malfunction.
2. Temperature issue: Industrial computers typically operate in harsh environmental conditions, and high temperatures or overheating may cause damage to circuit board components or soldering problems. Poor heat dissipation or system failure can also accelerate the aging and damage of circuit boards.
3. Electromagnetic interference: Industrial computers are usually used in industrial environments with poor electromagnetic conditions, and electromagnetic waves and interference may cause circuit board failures. Unreasonable circuit board design or lack of effective electromagnetic shielding measures can also increase the risk of electromagnetic interference.
4. Overcurrent or overvoltage: Unstable power supply voltage, lightning, etc. may cause overcurrent or overvoltage, leading to damage to circuit board components. The failure of protective components on the circuit board may also lead to overcurrent or overvoltage issues.
5. Component aging or damage: Capacitors, resistors, integrated circuits, and other components may age and experience performance degradation after prolonged use. Damage to components caused by mechanical impact, vibration, and other factors can also lead to circuit board failures.
6. Abnormal signal input: Abnormal voltage, current, signal or data input may cause circuit board failure. For example, signal inputs such as overload, short circuit, and error can all cause damage to the circuit board.

Obstacles. (6) Touch screen driver installation error. Common faults and troubleshooting of resistive screens: 1. The resistive touch mouse only moves within a small area or the resistive touch screen is inaccurate. This situation usually occurs during the first installation of the driver. Please run the touch screen calibration program
Read and write. 5. Network card is a communication network card, also called network card, which is a network device connecting the LAN and the Internet. The network card is inserted into the expansion slot of the computer motherboard, and there is a port on the network card that is connected to the network communication medium (such as twisted pair cable, coaxial cable, fiber optic cable, etc.) to exchange data with the network through the network card. Network cables enable resource sharing. 6. Sound card is the main component of multimedia computers. The sound card includes the hardware required for recording and playing Sound.7. The main function of a graphics card is to process programs based on instructions and related data provided by the CPU. The process and results of program execution are then converted into a display

Methods for repairing faults in industrial computer circuit boards
1. Power check: Confirm if the power cord of the industrial computer is connected properly and if the power plug is securely plugged in. Use a multimeter or other tools to check if the power supply voltage is stable and if there are any abnormal fluctuations.
2. Resistance measurement: Use a multimeter to measure the resistance value on the circuit board and check if the resistance is open or abnormal. Pay attention to checking for burnt black marks on low resistance resistors and whether high resistance resistors are damaged.
3. Voltage measurement: When the circuit board is powered on, use a multimeter to measure the voltage value at key points. Compare the measured value with the normal value to determine if there is any abnormality in the circuit.
4. Current measurement: Use an ammeter or multimeter to measure the current value on the circuit board. Check whether the current exceeds the rated value of the component and whether there is a short circuit or leakage phenomenon.
5. Capacitor inspection: Capacitor damage is one of the common circuit board faults. Check if the capacitor bulges, leaks, or has decreased capacity. Use a multimeter to measure the capacity and leakage of capacitors, and replace damaged capacitors if necessary.
6. Inductance and transformer inspection: Check whether the inductance, transformer and other components are overheating, deformed or damaged. Use a multimeter to measure the inductance or resistance of the transformer winding to determine if it is normal.

However, its application effect is very good, so automation in China will become increasingly important in industrial development. During the verification phase, engineers will temporarily replace industrial control computers with PCs, and professional industrial control computer equipment will still be used after verification. In short, practice has proven that industrial computers can solve professional problems, but civilian products cannot replace them. In the Industry 4.0 environment, large-scale, personalized, and customized are the future development trends. With the emergence of new technologies such as 5G, autonomous driving, the Internet of Things, and artificial intelligence, although the performance of industrial control computers is not good, their application effects are very good. Therefore, they will become increasingly important in industrial development
