Problems solved by technology

[0004] At present, there is no relevant automatic detection method. Usually, it relies on manual point-to-point testing on the output socket, which not only has potential safety hazards, but also has many When there are hundreds of points, it is time-consuming and laborious, and the integrity of the test cannot be guaranteed

Embodiment Construction

[0027] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0028] The block diagram of test equipment of the present invention is as figure 1 As shown in the figure, it is designed according to 3 AC relay groups and 1 DC relay group. According to different tested systems, relay groups can be increased or decreased as required.

[0029] The test equipment includes single-chip microcomputer control and data acquisition unit, multi-channel switching unit, power distribution control signal drive output, adapter cable and computer. The test equipment is mainly used to test the voltage value of multiple AC and DC signals.

[0030] The computer is connected to the test equipment through the RS232 interface, the test command is sent and the test result is received through the RS232, and the test result is displayed on the computer screen.

[0031] The single-chip microcomputer control and data acquisition unit includes severa...

Abstract

The invention relates to a radar center power distribution box offline automatic detection system and method. The system comprises a multi-channel switching unit, a single-chip microcomputer control and numerical control collection unit, and a power distribution control signal driving output module. Through the single-chip microcomputer control and numerical control collection unit, the power distribution control signal driving output module is controlled to control on or off of the multi-channel switching unit for a power distribution work state of each circuit required for a radar center power distribution box, so as to collect a detected signal. The radar center power distribution box offline automatic detection system and method greatly improve security, convenience, compatibility andtraceability of system test while greatly enhancing test efficiency.

Description

technical field [0001] The invention belongs to the field of radar testing, in particular to an off-line automatic detection system and method for a radar central distribution box. It is a method for product design and testing. Background technique [0002] As one of the key subsystems of the radar, the radar central distribution box is responsible for the important task of providing power for each subsystem of the radar. It is responsible for distributing the three-phase alternating current (AC380V) sent by the power station to each unit according to the needs of each power unit and providing control and protection. [0003] The radar central distribution box needs to provide AC and DC power supply for a dozen or even twenty subsystems. DC power supply will involve multiple varieties (such as +24V, +36V, +48V, etc.), while AC power supply must provide accurate phase, line (U, V, W, N, PE) and size (AC220V, AC380V). Wrong phase, wrong line, wrong value, otherwise it will ...
