[0025] Specific implementation mode three: the following combination image 3 Describe this embodiment, this embodiment is a further description of Embodiment 1 or 2, the difference between this embodiment and Embodiment 1 or 2 is that the tester also includes a printer 8; the print signal of the microprocessor 3 The output end is connected to the print signal input end of the printer 8 .

[0026] working principle:

[0027] After power-on, the multi-channel acquisition circuit will work at the same time. Taking the first channel as an example, the microprocessor 3 outputs a high level, which makes the output terminal of the solid-state relay controller 4 conduct, so that the activation circuit is in the conduction state. At the same time, the microprocessor 3 is in a cyclic detection state for the voltage input to the microprocessor. When the switch of the 28V battery to be tested is turned on, the current flows through the resistor, the solid state relay controller 4 and th...

Abstract

The invention relates to an activation circuit tester, which aims to solve the problem that the common tester can not be used for carrying out a big-current test within a short time, i.e. the load capability of an emission control ignition power. A current sensor collects current in an activation current loop in the activation circuit; a current signal is sent to the analog signal input end of an analog-digital converter; the digital signal output end of the analog-digital converter is connected with the current detection signal input end of a microprocessor; the relay control signal output end of the microprocessor is connected with the relay control signal input end of a solid relay controller; the circuit control signal output end of the solid relay controller is connected with the circuit control signal output end of an activation circuit simulator; the switching control signal output end of the activation circuit simulator is connected with the switching control signal input end of the solid relay controller; and the switch of the solid relay controller is connected into the activation current loop in series. The activation circuit tester can be used for multiple types of emission control butt joint for realizing emission control function tests and power supply performance tests.

Description

technical field [0001] The present invention relates to active circuit testers. Background technique [0002] As an important part of the weapon system, the launch control system's most critical function is to implement safe and reliable launch control to ensure the effective interception of the target by the weapon system. [0003] The most critical technical link in the launch process is the launch sequence control. Due to the rapid response requirements of the weapon system, the launch sequence generally adopts the irreversible sequence control mode. The content and logic of the control sequence are relatively complicated. The launch sequence control can be completed in a relatively short period of time. In this process, the launch control system must not only complete multi-channel battery activation control, voltage detection control, power transfer control, parameter binding, verification and start-up flight control, etc. The ignition control of the main and auxiliary...
