The invention relates to a hardware interlocking control system of a heat preservation cabin cover electromagnetic lock and a cover opening and closing hydraulic device and belongs to the field of interlocking control. The objective of the invention is to solve a problem of tedious manual power-off operation or unreliable software interlocking. The system comprises a host, a heat preservation cabin cover electromagnetic lock, a cover opening and closing hydraulic device solenoid, a power supply, a controller and an electromagnetic relay. The controller is connected with the control end of theelectromagnetic relay and used for controlling switching on / switching off of a normally-opened contact and a normally-closed contact of the electromagnetic relay so as to control on / off of the heat preservation cabin cover electromagnetic lock and the cover opening and closing hydraulic device. Thus, it is achieved that by controlling the normally-opened contact and the normally-closed contact ofthe electromagnetic relay, closing of the heat preservation cabin cover electromagnetic lock during marching is ensured; when the emission is required, the heat preservation cabin cover electromagnetic lock is firstly unlocked, and then the cover opening and closing hydraulic device is controlled to open the cover; and meanwhile, interlocking control can be achieved only by one relay, so stabilityand reliability of the system are greatly improved.
Description
technical field [0001] The invention relates to the technical field of interlock control, in particular to a hardware interlock control system for an electromagnetic lock of a heat preservation hatch cover and a hydraulic device for a switch cover. Background technique [0002] In order to ensure the temperature, rainproof and rigidity of the insulation cabin during the march of the launch vehicle, 1-3 electromagnetic locks are generally installed at the opening and closing of the insulation cabin cover, and multiple electromagnetic locks are connected in parallel. After the 24V DC is connected, the electromagnetic The lock generates suction to ensure the reliable closing of the insulation hatch. During the marching process, the electromagnetic lock of the thermal insulation hatch is energized to maintain the suction state. When the launch vehicle launches, it is necessary to open the thermal hatch cover. Open it, and then proceed to the subsequent launch mission. If the e...
