Problems solved by technology

In this case, considering the real-time nature of the transmission and control operation, it is impossible to have too much reserved time for the operator to travel between the front and rear ends in time to perform AC power distribution control operations and status checks; When AC is powered on, the state of the front-end transmission and control equipment is out of control, and it is easy to cause unexpected problems

Abstract

The invention provides a far-end alternating-current distribution control circuit for a transmission control device and a control method of the far-end alternating-current power distribution control circuit for the transmission control device. Two momentary push button switches are applied in the circuit, the electricity utilization for work of coils of two electromagnetic relays is controlled through certain access design, contacts of the two electromagnetic relays control output of alternating-current signals, and therefore a rear end worker can press down or restore the two momentary push button switches alternately to control the alternating-current distribution of the transmission control front-end device to switch on and off. The operating method is simple, power distribution control signals are accurate and reliable, the alternating-current distribution control over the front-end device can be accurately completed, and the operation executing safety can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of emission control, and in particular relates to a remote AC power distribution control circuit for emission control equipment and a control method thereof. Background technique [0002] In the field of launch control, due to the limitation of some external conditions, the input voltage of the launch control equipment is an AC signal, and through the secondary conversion of the internal circuit, it provides the required DC power for the components and functional modules inside the equipment. Generally, the AC power on and off of the equipment can be controlled through the AC power distribution switch on the panel of the transmission control equipment. [0003] In the technical document "Missile Test Launch and Control System" published by Aerospace Press, the description of the basic composition principle of the test launch and control system mentions that: the ground power supply supplies the working power...
