Description

The utility model relates to railway automation and serves to control the position of the turnout in accordance with the requirements of the Rules for the Technical Operation of Railways (PTE).

As an analogue and prototype adopted "Device for monitoring the position of wits relative to the frame rails of the railroad switch", patent No. 2222450 from 01/27/2004, characterized by the fact that the electromagnetic sensors of the device are installed in the necks of the frame rails and on the foundation square of the railroad switch and oriented by sensitive elements to the surface of the witches in the area between the heads of the bolts of the working rod of the drive and on the lower side face of the base of the wit, and the oscillation excitation schemes are made with the possibility of the excitation of oscillations, the duration of which is proportional in the interval of controlled values to the distance between the wits and sensitive elements of the sensors. The disadvantage of this device is to control only the position of the wits relative to the frame rails. In this case, the closed condition of the switch electric drive is not controlled. Those. the state of the switch is not controlled in which the wits are held by the electric drive mechanism in the pressed position. This condition is called closed and its violation can lead to spontaneous movement of wits under a moving train and the derailment of the train.

The inventive device for monitoring the position of the switch contains at least 4 sensors for monitoring the position of the wits D1, D2, D3, D4 located in the necks of the frame rails and on the foundation square, by analogy with "Device for monitoring the position of the wits relative to the frame rails of the switch" патент Patent No. 2222450 of January 27, 2004, and at least 4 sensors for monitoring the position of the knife levers of the automatic switch of the electric switch D5, D6, D7, D8 installed in the electric drive casing, 8 identical matching schemes communication with signals from SSD sensors, the outputs of which are connected to the inputs of microcontrollers for processing signals from MK1 and MK2 sensors, the outputs of which are connected to the inputs of the “I” information matching circuit, the output of which is connected to the input of the data transmission and reception system SPI1 to the electric signaling station (EC) . At the EC post, the information enters a similar SPPI2 circuit, the outputs of which are connected to the inputs of two microcontrollers MK3, MK4, the outputs of the microcontrollers are connected to two control circuits of the actuating relays UVIR, at the outputs of which executive relays for controlling the position of the turnout switch PC and MK are connected.

The objective of the invention is to increase the safety of train traffic and increase the reliability of information about the state of the turnout switch by monitoring the closed condition of the turnout electric drive.

Figure 1 presents a block diagram of the floor of the proposed device, figure 2 is a block diagram of the post part of the proposed device, figure 3 is a diagram of the placement of sensors in the switch electric drive.

A device for monitoring the position of wits relative to the frame rails of the turnout works as follows:

Figure 1 shows a block diagram of the floor of the device. Coordination schemes with the signals of the SSD sensors generate control pulses by analogy with the "Device for controlling the position of wits relative to the frame rails of the turnout switch", patent No. 2222450 of January 27, 2004, which are fed to the inputs of microcontrollers MK1, MK2, which process the signals and issue codes the status of all sensors that are fed to the matching circuit “AND”. The coincidence circuit “AND” gives the status codes of the sensors to the information reception and transmission circuit only if these codes coincide from both controllers. From the output of the “AND” coincidence circuit, the codes are sent to the SPPI1 information reception and transmission circuit, which transmits them to the communication line with the post unit of the device.

Figure 2 shows a block diagram of the fasting part of the device. Code signals from the communication line are fed to the input of the transmission and reception scheme of information SPPI2. From the output of the SPPI2 circuit, the code signals are fed to the inputs of the MKZ, MK4 microcontrollers, which logically process the sensor signals according to the principle of the presence or absence of metal masses in their control zones by analogy with the signal processing in the “Device for monitoring the position of wits relative to the frame railroad switches”, patent No. 2222450 dated January 27, 2004, and they verify the correctness of mutual operation, if there is a mismatch in the operation, the microcontrollers go into the off state, thereby ensuring the so-called protective failure of railway automation. At the outputs of the microcontrollers MK3, MK4, depending on the results of the logical processing of the sensor signals, control signals are generated for controlling devices for activating the actuator relays UVIR. Each IWIR circuit checks the coincidence of control signals from both controllers and turns on the executive relay; when the signals from the microcontrollers are out of alignment, it goes into a protective failure and turns off the executive relay.

Figure 3 shows a sketch of the placement of the sensors in the switch electric drive. Sensors for controlling the position of the knife levers of the automatic switch of the switch electric drive are located in such a way that the presence of the lever ferromass is fixed in its extreme positions with a gap of no more than S *. In this case, due to the rigid mechanical connection of the knife levers and control rails of the electric drive, the position of the knife levers of the automatic switch determines the final position of the switch.
