Measurement and control system design for air traffic control radar power supply - Power Circuit - Circuit Diagram

With the rapid development of the air traffic control radar system and the continuous advancement of its technology, the requirements for the internal control and control system of the air traffic control radar are getting higher and higher. As the power source for the normal operation of the air traffic control radar, the measurement and control of the air traffic control radar power supply system is even more important. Whether the power supply works normally or not will directly affect the performance of the air traffic control radar. Therefore, the power supply measurement and control system is an indispensable part of the air traffic control radar.
In order to troubleshoot the power supply, it is necessary to know the status of the power failure in real time [3]. This requires that the power supply real-time fault data can be captured at the moment of power failure, and can be stably stored in the fault environment, thereby real-time measurement and control of the system power parameters, digital information exchange and fault record display, etc., thereby reducing The skill requirements of operators and maintenance personnel improve the reliability of the system and reduce the average repair time of system failure [4].
1 System Overall Composition The overall composition of the design system is shown in Figure 1. It mainly includes the PC104 embedded computer, the sensor and its detection circuit part, the contactor and its control detection circuit part.
