Embodiment 2

[0066]Please refer toimage 3,image 3It is a flow block diagram of a control method conducive to a control device associated with the test vehicle 1 in the ACC. A control method conducive to the control device of the test vehicle 1 in the DC, the control method includes the step of: Step S1, when the moving strip 1 switches the transaction, first turn on the AC return line 3, The AC power supply line 4 is again turned on; step S2, when the moving line 1 is switched to DC, first turn on the DC return line 6, and then turn on the DC power line 5.

[0067]Among them, in step S1: first closing the AC return control switch 31 on the AC return line 3, then sequentially closes the AC power supply control switch 41, the AC power separation switch 42, the circuit breaker 43 turns on the AC power line 4; when it is necessary The AC power supply control switch 41 is disconnected, and the AC power separation switch 42, the circuit breaker 43, thereby turning off the AC power line 4, and then discon...

Abstract

The invention relates to a control device for a test run dynamic adjustment line in alternating current and direct current and a control mode thereof. The control device comprises a dynamic adjustment line, a steel rail, an alternating current power supply line, an alternating current return line, a direct current power supply line and a direct current return line. The dynamic adjustment line is connected with the alternating current power supply line or the direct current power supply line. The steel rail is connected with the alternating current return line or the direct current return line. When the dynamic adjustment line needs to be switched into alternating current, the alternating current return line is switched on firstly, and then the alternating current power supply line is switched on. When the dynamic adjustment line is switched into direct current, the direct current return line is switched on firstly, and then the direct current power supply line is switched on. The control device has the advantages that the alternating current return line is designed to realize alternating current return, and normal movement between the alternating current circuit and the direct current circuit is ensured through control between specific switches.

Description

Technical field[0001]The present invention relates to the field of communication, in particular, is a control device and control method therefor regarding the test vehicle in the DC.Background technique[0002]Urban orbit vehicles need to perform a large number of steps and example tests before assembly, not debugging, to verify that all aspects of the vehicle meet the requirements of vehicles to enter debugging and operations. Therefore, the test vehicle is a must-have condition for the vehicle test, and the prior art test trump line has the following defects and deficiencies:[0003]First, the power supply mode of the test vehicle in the prior art is a relatively single, either alone, either alone for communication, and DC is returned by the steel rail, while the steel is not able to reflow. Realization, leading to communication is not working properly and cannot meet the requirements of the test.[0004]Secondly, in the prior art test vehicle is in return, most of the steel tract is re...
