With the development of society and the improvement of the economy, China has achieved rapid development in the industrial field. Whether in the paper industry, the food industry, or the chemical and electric power industries, DCS is used to supervise the production status and production processes, thereby promoting production quality. And the improvement of production safety, how the DCS operating conditions have a direct impact on the production process. Strengthening the preventive maintenance management of DCS can effectively prevent common faults of equipment and bring more benefits to enterprises. Relevant departments must pay attention to them. It is very important to prevent and maintain the automatic instrumentation equipment, which can make the automatic instrumentation equipment not keep too many faults during the operation, make the equipment operate in a safe environment, and make the equipment last longer. Therefore, it is very necessary to establish a complete instrument inspection system, and arrange professional management personnel to carefully divide the scope of each management inspection and set the best path for inspection. At least twice a day. Inspection, so that the potential failure of the automation equipment can be discovered in time. When the personnel inspect the equipment, the inspection information should be recorded. If there is any problem, it should be reported to the higher-level department in time and the equipment should be repaired. The probability of a device having a security risk. If you want to prevent DCS failure, you must also implement system fault prevention and maintenance. Specifically, it is through the opportunity of overhaul of the unit to carry out comprehensive preventive maintenance of the system, so as to eliminate the hidden troubles of the fault by mastering the operating state of the unit. For this reason, during the overhaul of the unit, it is necessary to do redundant testing of the controller, redundant power supply and server, and do the cleaning work inside the equipment. Second, the detection of the power supply line of the equipment is required to ensure that the line has sufficient power supply capability. In addition, system grounding detection is required, that is, the ground resistance, terminal and grounding resistance are tested, and the system grounding resistance is ensured. In addition, before the equipment is overhauled, an effective backup of the software data is required to achieve reliable storage of the system data. In the management of instrument automation equipment, TPM management measures can be implemented. TPM is full production maintenance or full production maintenance. Specifically, it is the development of standardized equipment operation, maintenance and maintenance measures, and then through the continuous improvement of management measures through practice, and then more standardized equipment management. To this end, the maintenance personnel must go to the equipment operation site to observe the facts and objects, and analyze and summarize the relevant laws according to the actual operation of the equipment, so as to make a reasonable equipment management plan. On this basis, it is necessary to carry out the formulation of equipment maintenance regulations, and to evaluate the maintenance and management of equipment, so as to optimize the maintenance and management of equipment. Daily maintenance and management work, as well as the inspection and management of automated instruments, can effectively prevent equipment failures. According to the maintenance and repair rules and regulations of the automatic instrument, and according to the actual work requirements, the instrument management and maintenance personnel can make the equipment inspection plan to set the scope, content and process of the equipment inspection. At the same time, the maintenance personnel should also carry out reasonable planning of the inspection route and time, so as to complete the effective inspection of the equipment in a short period of time, and then effectively improve the efficiency of the preventive maintenance work of the equipment. In addition, for critical automated instrumentation equipment, maintenance personnel need to develop a special inspection management plan to strengthen the management and maintenance of the system. For example, for electrical automation instruments and equipment that are easy to accumulate and deposit grease, such as liquid level gauges, differential pressure transmitters and pressure transmitters, a reasonable sewage disposal plan should be established. For regulating valves and flowmeters such as vortex and electromagnetic, it is necessary to develop a winter insulation maintenance plan to ensure the normal operation of instrumentation equipment. Automated instruments have superior automation performance, which also makes them susceptible to external factors. Common influencing factors are lightning, corrosive gases, coastal environment and other factors, which we can not control, so we must improve and optimize its internal structure, and take scientific measures to control the external factors, so that The application value of automation equipment is enhanced. In order to effectively prevent the failure of automated instrumentation, it is necessary to carry out equipment maintenance work by using appropriate instrument maintenance methods. To this end, equipment maintenance personnel must also strengthen the learning and utilization of various common maintenance methods in order to achieve accurate positioning of equipment failures and hidden dangers, and then the occurrence of faults is suppressed. For example, the maintenance personnel can observe the instrument using the observation method to judge the running state of the device by observing whether the instrument has aging, water inflow and abnormal sound. In addition, maintenance personnel should also strengthen the use of various methods such as signal measurement and replacement to effectively eliminate system failures. For example, when making quick judgments on meter problems, you can use the form of signal input. The integrated calibrator is used to input the appropriate signal into the card, and the DCS display can be used to judge whether the loop is faulty. In the same way, the regulator valve output signal can be analyzed to see if the regulator valve is faulty. In daily maintenance work, maintenance personnel also need to use equipment such as a multimeter to measure the automatic instrument to analyze the potential failure of the instrument.
