The customized control mode of pulse air valve and the precise coordination of equipment control system are first reflected in the customized adaptation of signal interface. According to the output signal type of equipment control system (such as analog quantity, digital quantity or pulse signal), the customized control module will be equipped with corresponding interface circuit to ensure that the control signal is not attenuated or delayed during transmission. For example, when the equipment control system outputs a 4-20mA analog signal, the control unit of pulse air valve will have a built-in signal conversion chip to accurately convert the analog signal into an execution instruction in the valve body, avoiding response deviation caused by signal mismatch, and laying the foundation for collaborative operation.
The compatibility optimization of communication protocol is the core guarantee of collaborative control. The customized control mode will be deeply developed for the exclusive protocol (such as Modbus, Profinet or private protocol) adopted by the equipment control system, and the corresponding protocol parsing module will be implanted in the control program of pulse air valve. This enables the two to realize two-way real-time interaction of data - the equipment control system can send switch instructions and adjust parameters in real time, and the pulse air valve can also instantly feedback the current working status (such as valve opening, pressure value) to form a closed-loop control. This deep integration at the protocol level avoids the "information islands" between different systems and increases the speed of collaborative response by more than 30%.
The implantation of the synchronous control algorithm solves the problem of timing consistency when multiple valves work together. In the equipment system that requires multiple groups of pulse air valves to work together, the customized control method will have a built-in high-precision clock synchronization module to calibrate the action timing of each valve through the synchronous pulse signal sent by the equipment control system. For example, in dust removal equipment, multiple pulse valves need to spray in sequence at preset intervals. The customized algorithm can ensure that the start-up time error of each valve is controlled within ±1ms, avoiding airflow interference caused by asynchronous action and improving the overall operation efficiency of the equipment.
The adaptive adjustment function allows the pulse air valve to dynamically match the load changes of the equipment. The customized control unit will collect parameters such as pressure and flow during equipment operation in real time, and automatically correct the valve opening through the preset PID adjustment algorithm. When the equipment load suddenly increases, the control module will quickly increase the valve opening to supplement the airflow; when the load decreases, the valve will automatically close to avoid energy waste. This "dynamic collaboration" capability makes the pulse air valve no longer a passive execution component, but an intelligent unit that can actively adapt to changes in equipment working conditions, significantly improving system stability.
Standardized transmission of fault diagnosis signals enhances the reliability of collaborative control. The customized control method converts the fault information of the pulse air valve (such as jamming, air leakage, overheating) into a standard fault code that can be recognized by the equipment control system and uploaded in real time through the communication bus. When an abnormality occurs, the equipment control system can immediately locate the faulty valve and trigger interlocking protection (such as shutdown, alarm) to prevent the spread of the fault. At the same time, the control module will also store the operating data before the fault, providing a basis for subsequent troubleshooting, and shortening the average fault handling time to half of that of traditional valves.
The hierarchical design of control authority meets the collaborative needs in different scenarios. The customized system will set up multiple levels of control authority: the equipment control system has the highest level of global control authority, which can set parameters and switch modes; the local control panel retains emergency operation authority for on-site debugging; the remote monitoring platform has status viewing authority to achieve multi-level collaborative management. This division of authority not only ensures the unity of system control, but also takes into account the flexibility of emergency operation, making the pulse air valve more flexible in complex working conditions.
The anti-interference design ensures the stability of coordination in harsh environments. The customized control method uses photoelectric isolation technology to block external electromagnetic interference (such as interference generated by motors and inverters), and installs shielding layers and surge protectors on the signal lines. Even in the strong electromagnetic environment of the industrial site, the transmission bit error rate of the control signal can be controlled below 0.01%, ensuring that the communication between the pulse air valve and the equipment control system is not interrupted and the instructions are not lost, providing guarantee for precise coordination from the physical level.
