Description

The utility model relates to an on-board temperature control system for nodes of rolling stock of railway transport, in particular, axle box wheels, but can be used on other types of wheeled vehicles to control various characteristics, for example, acceleration (deceleration), vibration, traction, etc. .

A known tracking system for accidentally heating roller axle boxes of wheel sets of railway cars for non-contact automatic detection of overheated axleboxes PONAB (Heated Emergency Buchs Detection Detector), which contains stationary single control points with proximity sensors - optical cameras with thermal radiation receivers, devices for receiving and transmitting information about the presence of an accidentally heated axle box, its location and temperature and communication lines with communication channels providing transmission of information about the presence of an accidentally heated axle box to the locomotive driver, and communication channels that provide coded information to the traffic light about the need to change the speed of the controlled train, while the communication line between the outdoor device and the traffic light is aligned with the rail circuit, and communication with the locomotive of the controlled train is carried out by to a radio signal. The tracking system also contains recording devices for recording and storing controlled information (patent RU No. 2337029, BKK 9 / 2006.01.04).

The disadvantages of the known system are as follows. In order to reduce the number of false train stops when roller axle boxes have increased heating, but do not pose a direct threat to the safety of train traffic, continuous monitoring of axle box heating is necessary. However, the safe interval of the train between the control contactless automatic points at a maximum emergency heating rate of the axleboxes and the narrow threshold temperature range of the necks of the axles of the axleboxes, at which the bearings are jammed, require frequent checkpoints, which increases the total cost of the control equipment in the area by several orders of magnitude the roads. Another disadvantage is the lack of accuracy of optical temperature sensors, which is affected by random exposure or, on the contrary, pollution of the translucent protection of the sensor, which change the luminous flux.

The objective of the utility model is to provide continuous monitoring of the heating of the axleboxes with a decrease in the number of false stops of trains, increasing the accuracy of measuring the threshold temperature of the necks of the axles of the axleboxes, as well as reducing the cost of control equipment.

The proposed on-board temperature control system for the nodes of the rolling stock of railway transport, according to the task, containing means for transmitting, recording, recording and storing controlled information associated with temperature sensors, a radio link of the system with a locomotive of a controlled train, characterized in that the means for transmission are made in in the form of transceivers installed in sealed monoblock cases equipped with an autonomous power source on rolling stock cars, registration, recording and storage means are made in the form of a terminal with a display and controls and are located in the driver’s cab, temperature sensors are additionally equipped with temperature signal to radio signal converters and radio modems, while temperature sensor measuring elements are installed directly in temperature measuring zones, signal converters and radio modems are installed in an additionally introduced sealed monoblock case with an autonomous power supply, and the monoblock case is installed di It is stationed with a measuring element and connected to the last wire connection, information display means are connected to the transmit-receive devices by wire connection, and the latter are connected to temperature sensors via a radio channel in the unlicensed frequency range.

The given set of features allows you to achieve your goal by installing temperature sensors directly in the measurement zone.

The utility model is illustrated by diagrams: figure 1 shows the elements of the on-board temperature control system of nodes installed on the lead head carriage; figure 2 - elements mounted on a slave head carriage; figure 3 - elements mounted on a motor car; figure 4 is a schematic view of a temperature sensor.

The temperature sensors 1 installed on the nodes of the bogies 2 of the wagons 3 are connected by a radio channel 4 with the means for transmission - a router 5 of the corresponding wagon. Routers 5 are also connected via radio channel to coordinators 6 installed in the head cars. The coordinators 6 are connected via cable 7 to the control unit 8, connected by cable 9 to the terminal 10, which are installed in the driver's cab. When transferring control from one cabin to another, information from routers 5 is transmitted to coordinator 6 of the now leading host carriage. The coordinator 6, the control unit 8 and the terminal 9 of the slave car are disabled.

The temperature sensors 1 installed on the nodes of the bogies 2 of the wagons 3 continuously measure the temperature and transmit data via radio channel 4 to the router 5 of the corresponding wagon. Routers 5 carry out preliminary processing, and also by radio, transmit data to the coordinator 6 installed in the head cars. The coordinator 6 collects temperature data from the routers 5 of all the train cars and transmits it via the communication cable 7 to the control unit 8, where they are processed. The measurement results are stored on the SD card and transmitted via cable 9 to the terminal 10, which is installed in the driver’s cab. When transferring control from one cabin to another, information from routers 5 is transmitted to coordinator 6 of the now leading host carriage. The coordinator 6, the control unit 8 and the terminal 10 of the slave car are disabled. In control unit 8, an external memory is installed in which temperature data for the trip is recorded, which can be transferred to the master's computer for further processing.

General control of the system, processing of results and information output is carried out from terminal 10. During the polling, the control unit 8 constantly compares the temperature difference between the monitored unit and the ambient temperature with a threshold (critical) temperature value, above which the sound and light alarms are triggered, and the display of the terminal 10 displays the location of the overheated node. In order for the locomotive team to be able to take timely actions to eliminate the situations that have arisen, another temperature threshold has been introduced - the warning temperature. The values of both the warning temperature and the superheat temperature are set by selecting the corresponding item in the menu of the control terminal 10.

The control unit 8, when the system is turned on, builds a radio network, polls the devices for their availability, availability, location, and then, with a frequency of 1 minute, polls the temperature of the devices, processes and outputs data to terminal 10.

Temperature sensors 1 (in a specific example, radio sensors) are designed to measure and transmit temperature values to a router 5 or coordinator 6 and are equipped with temperature signal converters 11 to a radio signal and radio modems 12, while the measuring elements 13 of the temperature sensors 1 are installed directly in the temperature measurement zones, the converters 11 the signal and radio modems 12 are installed in an additionally introduced sealed monoblock case 14 with an autonomous power source, and the monoblock case 14 is installed di stationed with the measuring element 13 and connected to the last wire connection 15.

The industrial applicability of the proposed system is confirmed by the fame of the elements used in its manufacture.
