Description

TECHNICAL FIELD

[0001] The present application relates to a control and detection integrated launch control system. BACKGROUND

[0002] Under the condition of rapid development of informatization, the degree of automation, electrification, digitization and intelligence of the launch control equipment of the aircraft is higher and higher, so that various faults may occur in the use and test of the launch control equipment, and the control equipment is required to have high reliability and safety. Under the new situation, the launch control equipment should be able to effectively deal with various unexpected situations, quickly test and maintain, and ensure the effective operation of the ground launch control system under the condition of simple launch area site facilities.

[0003] Most of the existing launch control equipment does not have detection means, which causes insufficient maintainability of the equipment and shortens the life cycle of the equipment. The control equipment with detection means mostly separates the control module and the detection module for independent operation, which not only increases the development cost, but also increases the installation space, which is not conducive to the development of small equipment. For example, a control system based on a meteorological detection rocket disclosed in CN112783023A takes a DSP processor module as the core, connects with the ground control system through a CAN bus communication module, communicates with other systems through an RS-422 serial communication module, and detects the power supply parameters of the rocket through an AD acquisition circuit, but the control and detection are separated into two systems, which increases the required space of the control system.
