Problems solved by technology

[0007] The functions of the 300T series ATP cabinet and the 200T series ATP cabinet are different. The 300T series ATP cabinet controls the vehicle at the safety level of C3 and C2. The cabinet has wireless communication terminal equipment to realize wireless communication, but it cannot communicate with LKJ; With C0 level car control, the cabinet has no wireless function and needs to communicate with LKJ
[0011] Therefore, the detection device of the 300T series vehicle-mounted cabinets in the prior art is not suitable for 200T vehicle-mounted cabinets

Embodiment 3

[0083] see image 3 , which is a schematic diagram of the speed simulator provided by the present invention.

[0084] The speed simulator provided in this embodiment includes: a square wave generating circuit 300a and a signal amplifying circuit 300b;

[0085] The square wave generating circuit 300a is used to generate square wave signals of different frequencies;

[0086] Since the speed signal received by the ATP cabinet is a square wave signal, it is necessary to generate a square wave signal to represent the speed signal, and square wave signals of different frequencies correspond to different speeds.

[0087] It should be noted that, the square wave generating circuit 300a can use FPGA to realize hardware circuit, and use a digital frequency synthesizer (DDS, Direct Digital Synthesizer) to realize frequency controllability.

[0088] The signal amplifying circuit 300b is configured to amplify the square wave signal and send it to the ATP cabinet.

Abstract

The invention provides a detecting device for a vehicle-mounted ATP equipment cabinet. The detecting device comprises a detecting host, a relay driving plate, a relay state collecting plate, a control plate and a speed simulation device. The detecting host is used for transmitting a relay driving signal to the relay driving plate. The relay driving plate is used for converting the relay driving signal into a simulation signal and then transmitting the simulation signal to the ATP equipment cabinet. The relay state collecting plate is used for collecting a state signal of ATP equipment cabinet relays. The control plate is used for converting the state signal of the relays into a digital signal and then transmitting the digital signal to the detecting host and further used for converting a control instruction of the detecting host into a simulation electric signal and then transmitting the simulation electric signal to the relay driving plate. The speed simulator is used for receiving a speed instruction transmitted by the detecting host, generating a corresponding speed signal according to the speed instruction and then transmitting the speed signal to the ATP equipment cabinet. Because a relay set gate is of a brand-new structure, the size is reduced greatly, the space is reduced, and cost is low. The speed simulator is used for generating square wave signals different in frequency and achieving speed controllability.

Description

technical field [0001] The invention relates to the technical field of train complete machine detection, in particular to a detection device for a vehicle-mounted train automatic protection cabinet. Background technique [0002] The 200T series on-board automatic train protection (ATP, Automatic Train Protection) cabinet belongs to the model CTCS2 level train control on-board equipment, and is an important technical equipment for high-speed railways. [0003] The ATP cabinet is set on the train, which can transmit the train driving permit information based on the track circuit and the transponder and monitor the safe operation of the train by using the target distance continuous speed control mode. Real-time monitoring of the train's running speed, running interval, and whether it is overspeeding can be completed. [0004] The series of vehicle-mounted ATP cabinets include: 200T EMU vehicle-mounted ATP cabinets, 200T catenary operation vehicle ATP cabinets and CTCS2+ATO tra...
