Description

Program-controlled power management system of track equipment test bench

Technical Field

The utility model relates to a track equipment test, concretely relates to programmed power management system of track equipment testboard.

Background

In the process of testing the track circuit frequency shift equipment, a plurality of frequency shift equipment need to be tested simultaneously, the power supply of each tested frequency shift equipment is frequently switched in the test process, the working current of each equipment is monitored, and the equipment with overcurrent and short-circuit faults is cut off and protected. The traditional programmable power supply can not meet the control requirement of monitoring the working conditions of multiple paths of loads, and if a relay or a circuit breaker is adopted to carry out hard switching on a direct-current power supply in the testing process, the power supply can be caused to generate ripple interference and power supply voltage interruption interference in the moment of switching, and certain damage is caused to the tested track circuit frequency shift equipment. If manual switching is adopted, the working efficiency of the test is reduced, and unnecessary economic loss caused by manual misoperation is possible.

Disclosure of Invention

In order to solve the problem, the utility model provides a programme-controlled power management system of track equipment testboard.

The technical scheme of the utility model:

a program-controlled power supply management system of a track equipment test bench comprises a test system main bench, a power supply distribution box and a test condition box; the system further comprises a programmable power supply; the power distribution box has a number of output ports.

The output port of the programmable power supply is connected with the power distribution box, each output port of the power distribution box is correspondingly connected with one test condition box, one test condition box is correspondingly connected with one frequency shift device, and the programmable power supply is connected with 220V alternating current to jointly form a power supply circuit.

The test system main station is respectively connected with the programmable power supply and the power distribution box through two paths of serial buses to form a control/fault detection circuit together.

Adopt above-mentioned system:

in the testing process, the main console of the testing system sends a control command to the programmable power supply through one path of serial bus, and the programmable power supply executes corresponding operations such as total power supply switching, voltage setting, total current setting and the like after receiving a correct control command; the test system main station sends a control instruction to the power distribution box through another path of serial bus, and the power distribution box receives the correct control instruction and then executes corresponding operation such as shunt power supply switching, current detection and the like; thus, each frequency shift device is independently controlled; and meanwhile, the test system main console monitors the current data transmitted by the programmable power supply and the power distribution box, judges the working condition of the tested frequency shift equipment according to the current data, and cuts off the tested frequency shift signal with a single-path fault if abnormal information such as current overcurrent, short circuit and the like is found, so that fault detection is realized.

Preferably, the test system has a main platform model: TC 2000R; the model of the programmable power supply is as follows: IT6722A 80V/20A; the model of the power distribution box: TC 2000R/P; test condition box model: TC 2000R/S; the frequency shift device model: ZPW CF-R, ZPW ZC2-R, ZPW CP 1-R.

The utility model has the advantages of, reasonable in design, simple structure carries out solitary power flexible switch and electric current, magnitude of voltage control to every load equipment, when being surveyed frequency shift equipment and appearing overflowing with short-circuit fault, can close this way mains operated alone, does not influence the quilt of other passageways and survey frequency shift equipment and accomplish the test, and whole switching is overshot and is passed through program control, need not tester manual operation, has avoided because of the equipment damage that human misoperation brought.
