Problems solved by technology

[0004] The existing railway passenger car power supply control system selects a single power receiving method, and cannot choose which way or which terminal connector receives power
Secondly, the existing railway passenger cars do not have an effective control logic to avoid the simultaneous power supply and power reception at one end of the railway passenger car
Finally, with the existing technical solutions, to realize the safety of power supply near the vehicle, the operators of the two adjacent vehicles must communicate in real time and implement correct operation, otherwise safety accidents will easily occur

Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0031] For such as figure 1 Based on the defects and deficiencies of the prior art shown, the present application proposes a novel on-board power supply anti-misoperation control circuit suitable for the transportation and installation of railway passenger cars. First, improve the choice of power receiving mode, and add two power receiving modes of "one-bit end power receiving" and "two-bit end power receiving" to provide power supply for vehicles; second, increase the current at the appropriate position of the power supply circuit Relays, contactors, etc. form a new type...

Abstract

The invention relates to a control circuit which is applied to a train. According to the method, a power supply circuit, a contactor, a relay and a switch module are included, the output end of the power supply circuit is connected with the input end of the contactor, the input end of the relay and the input end of the switch module, the output end of the contactor, the output end of the relay and the output end of the switch module are all connected with a load, and the relay is used for identifying the power receiving position of a train. By designing the control circuit for preventing the misoperation of a temporary train power supply of a passenger train, the misoperation of the temporary train power supply is avoided, the safety and the practicability of railway passengers and the operation convenience of workers are improved, and safety accidents caused by manual misoperation are avoided.

Description

technical field [0001] The present application relates to the field of anti-misoperation technology, in particular to a control circuit. Background technique [0002] With the high-speed development of railway vehicles, people's requirements for ride quality are getting higher and higher, and people's requirements for train safety are also getting higher and higher. Important, but improving the practicability of power supply near vehicles should also follow the development trend, and optimize the structure to keep pace with the times. [0003] The power supply control technology for adjacent trains adopted by the existing railway passenger cars is mainly to select the power supply for adjacent trains by the electric car through the rotary switch after the generator set of the adjacent trains is started and selects the power supply for the adjacent trains through the rotary switch, so as to achieve a kind of power supply for the entire train Way. The electric railway passen...
