Intelligent measurement and control apparatus of high-pressure isolation switch operating mechanism and method thereof

The invention provides an intelligent measurement and control apparatus of a high-pressure isolation switch operating mechanism and a observing and controlling method thereof, wherein the apparatus comprises an advanced RISC machines (ARM) chip, a complex programmable logic device (CPLD) which is connected with the ARM chip, solid-state relays, power relays and a humidity-temperature sensor which are respectively connected with the CPLD, and a current transformer, an angle sensor and a keyboard which are respectively connected with the ARM chip; the ARM chip is connected with a remote computer through a communication module. When receiving an opening (closing) instruction, the ARM chip first outputs an instruction to close one of the power relays; and after 0.5 seconds, the ARM chip outputs a triggering command to the solid-state relays to close the solid-state relays. When a motor starts to move and arrives at an opening (closing) position, the ARM chip cancels a triggering signal to the solid-state relays;
