Problems solved by technology

[0003] At present, the pilot controller itself does not have the function of identifying two independent environmental forces, especially the overload, which leads to a decrease in the independence, intelligence and safety of the pilot controller
According to the design idea of ​​the original pilot controller, external devices such as overload switches need to be added to realize the identification of the second-level environmental force, which greatly increases the equipment volume of the entire system and hinders the development trend of aircraft miniaturization
At the same time, at present, there is no relevant research on the intelligence of the controller, and it mainly stays at the level of passively receiving and executing instructions. It is urgent to carry out relevant research in this field

Embodiment

[0044] The invention adopts the DSP chip of TI company as the core processor, and the CPLD chip as the interface chip to complete the interface matching of the bus, and at the same time realize the 1s power-on blocking function, so as to ensure that the controller will not generate relay misoperation during power-on. The relay circuit is built with a combination of electromagnetic relays and solid state relays. The 1553B bus interface circuit adopts the B61580 chip of the 772 Institute to realize the bus communication, and the sub-address code of the pilot control system is RT15; the 1553B bus is a dual-redundant bus, divided into A and B buses, and has high reliability. During use, the MEMS sensor will sense the overload of the pilot controller in real time. When the overload value of 6.5g is sensed, the CPU will control the action of the overload identification relay, providing a prerequisite for the secondary release. The pilot controller is divided into four modules, which...

Abstract

The invention relates to a denotation controller with a two-stage independent environmental force recognition function, which is characterized in that recognition for a two-stage environmental force of engine ignition signals and powered phase overload signals through integrating an electromagnetic relay and an MEMS sensor, and the integration, the autonomy and the security of the denotation controller are improved. The denotation controller realizes communication with a control system and a programmable execution mechanism through a 1553B bus technology and an RS485 bus technology, and the communication reliability of the system is improved. Meanwhile, in order to improve the reliability of the denotation controller at the power-on moment, a function of power-on IO output blocking is adopted, and the anti-interference capability and the reliability of a product in hardware are improved.

Description

technical field [0001] The invention relates to a pilot controller with two-stage independent environmental force recognition functions, and belongs to the technical field of aircraft safety detonation control. Background technique [0002] The pilot controller is an important device of the fuze system. Its main functions include identifying two independent environmental forces; completing the communication with the control system and the programmable actuator through the bus; receiving the command of the control system in flight to disarm the programmable actuator; Self-destruction function and the realization of system status indication and other functions. [0003] At present, the pilot controller itself does not have the function of identifying two independent environmental forces, especially overload, which leads to a reduction in the independence, intelligence and safety of the pilot controller. According to the original design idea of ​​the pilot controller, it is ne...
