Detailed Description

Although the application is illustrated and described herein with reference to specific embodiments, the application is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the application.

Referring to fig. 1, the motor car signal simulation apparatus of the present application is divided into a signal detection system 100 and a signal reception system 200. The signal detection system 100 is used for simulating various signals sent by a trailer of the motor train unit, and the signal receiving system 200 is used for simulating the operation of a motor train unit in the motor train unit by receiving the signals.

The signal detection system 100 includes: the system comprises an alternating current-direct current conversion module 110, a brake signal module 120, a gate control signal module 130 and a safety signal module 140, wherein all the modules of the signal detection system 100 are connected to a reconnection plug 150 through lines. The signal receiving system 200 includes: the braking module 220, the gating module 230, the safety module 240, and the modules of the signal receiving system 200 are connected to the reconnection socket 250 through wires. The reconnection plug 150 is connected to the reconnection socket 250.

In use, the signal detection system 100 may be a simple detection instrument, and the signal receiving system 200 may be a device on the motor vehicle responsible for the corresponding action. In such a case, the signal detection system 100 sends out a detection signal instead of the trailer. Therefore, even in the detection environment with only the motor train and no trailer, whether the motor train can normally receive various signals of the trailer or not can be detected, and corresponding action can be carried out.

The modules of signal detection system 100 and signal reception system 200 are described below with reference to fig. 2-5.

The alternating current-direct current conversion module 110 has the functions of converting an external AC220V voltage into a DC110V voltage and providing a test power supply for the device, meanwhile, a DC48V, a DC36V and a DC24V power supply are generated through the conversion module, the output current is adjustable within 0-300mA, a FLUKE TP2 probe (mainly used for detecting compact or sunken test points) is adopted, the diameter of the probe is 2mm, and the direct current conversion module is mainly used for providing a direct current power supply for a power supply cabinet test excitation signal of a motor train unit train, air conditioner fault detection and the like.

The brake signal module 120 includes closed circuit breakers K-5, K-6, K-7, K-8 and an indicator light L1. The circuit breakers K-5, K-6, K-7, K-8 may generate signals corresponding to train braking, train release, train hold pressure, and train emergency when closed. When the braking module 220 receives the signal, the braking module performs a braking operation, and at this time, the test lamp L1 is turned on to indicate that the braking operation is normal.

The gate control signal module 130 is powered by the ac-dc conversion module 110 and can generate signals corresponding to a right gate enable, a right gate open, a right gate close, a left gate enable, a left gate open, and a left gate close, and includes an indicator light L2. After the door control module 230 receives the signal, the door control system is operated in the motor train. The door control module 230 includes relays KA-1, KA-2, KA-3, KA-4, KA-5, and KA-6, which correspond to signals of a right door enable, a right door open, a right door close, a left door enable, a left door open, and a left door close, respectively. With the relays KA-1, KA-2, KA-3, KA-4, KA-5, and KA-6 closed, the indicator light L2 will be illuminated to indicate that the door control action is normal.

The safety signal module 140 includes circuit breakers K-1, K-2, K-3, and K-4, and can simulate safety signals of a trailer, such as a door state, a shaft temperature alarm, a fire alarm, and a brake release signal, by closing the circuit breakers K-1, K-2, K-3, and K-4, respectively. The signal receiving system 200 comprises I/O feedback signal contactors KM-1, KM-2, KM-3 and KM-4, after receiving signals sent by the safety signal module 140, corresponding coils are powered, the I/O feedback signal contactors KM-1, KM-2, KM-3 and KM-4 are respectively powered, corresponding safety signal displays DI1-1, DI1-2, DI2-1, DI2-2, DI3-1, DI3-2, DI4-1 and DI4-2 on the power vehicle are lightened at the moment, for example, when the contactor KM-1 is powered, the safety signal displays DI1-1 and DI1-2 are lightened. At the moment, the motor car performs corresponding actions, such as traction locking.

Fig. 7 shows a circuit breaker as used in the present application, which for example employs a siemens 5SY5110-7CC direct current single pole circuit breaker.

Fig. 8 illustrates a reconnection plug and reconnection socket as used herein, for example a 35+3x4-B type reconnection socket and corresponding reconnection plug. The modular design has expandability, and the wiring point positions are changed by replacing the reconnection plugs, so that the modular design can be used for other motor train unit tests.

While preferred embodiments have been shown and described herein, it should be understood that these embodiments are presented by way of example only. Numerous modifications, changes, and substitutions will occur to those skilled in the art without departing from the spirit of the invention.
