Electric primer emission controller based on CAN bus

Abstract

The invention discloses an electric primer emission controller based on a CAN bus. The controller comprises a CAN bus circuit, an MOS transistor circuit, a voltage stabilizing circuit, an electric primer resistance detection circuit, a protection circuit and a circuit control system, wherein the protection circuit is connected with the MOS transistor circuit and the electric primer resistance detection circuit; the voltage stabilizing circuit is connected with the power supply and is connected to the output end of the MOS transistor circuit; one end of the electrical primer resistance detection circuit is connected with electric primer, and the other end is connected with the circuit control system; the circuit control system is connected with a PC terminal through the CAN bus circuit, andthe PC terminal displays the state of whether the electric primer resistance is abnormal and sends a transmission control instruction; the circuit control system judges whether the transmission control instruction sent by the bus is valid or not, and controls the on-off of the MOS transistor circuit; and the input end of the MOS transistor circuit is connected with the circuit control system, andthe output end of the MOS transistor circuit is connected with an electric primer transmission group. According to the electric primer emission controller, the power-on isolation of the electric primer, the detection of the electric primer resistance and the remote emission of the electric primer can be realized.

Description

technical field [0001] The invention belongs to the field of weapon launch intelligent control, in particular to a CAN bus-based electric primer launch controller. Background technique [0002] With the development of military science and technology, the idea of ​​unmanned combat has begun to be valued by the armies of various countries, and remote control of weapon launch is a necessary condition for unmanned combat; because traditional impact primers require complex mechanical structures to assist in launching, electric primers give It can be fired at a certain voltage and current, and is widely used in the launch of smart weapons. [0003] At present, the firing of most electric primers is basically directly connected to a power supply at both ends of the electric primer to complete the firing without the remote operation of the electric primer control, and because it does not have the resistance value detection capability of the electric primer, the resistance value stat...

Problems solved by technology

[0003] At present, the firing of most electric primers is basically directly connected to a power supply at both ends of the electric primer to complete the firing without the remote operation of the electric primer control, and because it does not have the resistance value detection capability of the electric primer, the resistance value state cannot be performed before firing However, due to the long-term storage of the electric primer, the abnormal resistance of the electric primer will cause the electric primer not to have the launch capability or the launch effect is not ideal; In the launch control, if the level isolation at the moment of CPU power-on is not performed, the pin level uncertainty at the moment of CPU power-on may cause misfire accidents caused by electric priming
