The train consists of a locomotive and a plurality of freight/passenger carriages, and usually the locomotive and each carriage are provided with two bogies, and each bogie comprises two axles. In the process of train advancing, the axle temperature detection of the axle has important significance for driving safety. Therefore, the following technical scheme is provided for the problems existing in the traditional axle temperature detection technology of the train.
Referring to fig. 1, in an embodiment, a train axle temperature detection apparatus provided in an embodiment of the present application includes a temperature sensor 12, a wireless acquisition module 14, a wireless receiver 16, and a ground controller 18. The temperature sensor 12 is provided to an axle 31 of a bogie of a train and detects the temperature of the axle 31. The wireless acquisition module 14 is electrically connected to the temperature sensor 12, and is configured to acquire temperature information output by the temperature sensor 12 and perform wireless transmission. The wireless receiver 16 is disposed near the track for receiving temperature information as the wireless collection module 14 passes by. The ground controller 18 is electrically connected with the wireless receiver 16 and used for receiving temperature information and transmitting the temperature information to an upper computer.
It is understood that the temperature sensor 12 is a sensor known in the art capable of detecting the temperature of the axle 31 and converting it into a corresponding output electrical signal, such as, but not limited to, a conventional digital temperature sensor. The wireless acquisition module 14 is a wireless transmission module or a wireless transceiver module with a certain communication distance in the field, and the specific type can be selected according to the signal receiving, temperature information storage and wireless transmission modes of the temperature sensor 12. The wireless collection module 14 can be powered by an independent power supply or can be connected to a device power supply of the train to realize power supply. The wireless receiver 16 is a wireless signal receiving module in the art, and the specific type can be selected according to the wireless transmission mode of the wireless acquisition module 14.
For any axle 31 of the bogie of the train, the temperature sensor 12 can be installed on the outer surface of the periphery of the axle 31 or the surfaces of two end parts, can be in direct contact with the axle 31 or can be in indirect contact with the axle 31 through a temperature conducting piece, the specific installation position can be determined according to the temperature measurement mode, signal transmission and other requirements of the temperature sensor 12, and the temperature sensor 12 can effectively and accurately complete axle temperature measurement in the train running process. The wireless collection module 14 may be mounted on a bogie, a vehicle cabin, or an axle 31, for example, but not limited to, the wireless collection module is integrally packaged with the temperature sensor 12 and then mounted on the axle 31, as long as the wireless collection module can ensure the circuit connection with the temperature sensor 12 and the communication connection with the wireless receiver 16 when passing through a set area.
The vicinity of the rail may be within a certain spatial range on either side of the rail, or within a certain spatial range of an area inside the rail (i.e. an area where two rails are formed opposite to each other), for example, a spatial area located in the vicinity of a web of any one rail (e.g. at a lateral distance of 1cm to 30cm from the web). The specific position near the track can be selected according to the receiving distance of the wireless receiver 16 and the wireless transmitting distance of the wireless acquisition module 14, as long as the wireless acquisition module 14 can be ensured to pass by, the wireless receiver 16 can effectively receive the wireless signal transmitted by the wireless acquisition module, and thus reliable reception of the temperature information can be realized. The wireless receiver 16 may be mechanically connected to the rail web or rail foot of the rail near the rail, or mechanically connected to the sleeper or directly installed on the ground, as long as it is ensured that the wireless acquisition module 14 effectively receives the wireless signal transmitted by the wireless acquisition module when passing through. It should be noted that the broken lines in fig. 1 indicate the track or the rails indicating the track, and the broken lines in the remaining drawings can be understood in the same way.
The surface controller 18 may be mounted near the track, for example, after being integrally packaged with the wireless receiver 16. The ground controller 18 may be mounted on a rail, tie, or other location on the ground so long as it is operatively and reliably electrically connected to the wireless receiver 16 to receive the signal output by the wireless receiver 16. The surface controller 18 may be a general control device in the art having data receiving, storing and communication interface functions, such as, but not limited to, a single chip, a raspberry pi, or an FPGA (Field-Programmable Gate Array). The ground controller 18 may be powered by an independent power source, a power arm of the track in which it is located, or a power substation. The upper computer is a monitoring device equipped in the train monitoring center, such as an operation terminal or a train dispatching management system.
During train operation, the wireless receiver 16 and the ground controller 18 can maintain a silent state due to the absence of signal wireless signal input when no train passes through a certain spatial range near the track. As the train passes, the wireless acquisition module 14 will travel with the train through a range of space near the track. At this time, the wireless receiver 16 disposed near the track receives the wireless signal transmitted by the wireless acquisition module 14, so as to establish short-term communication with the wireless acquisition module 14. The temperature information collected by the temperature sensor 12 is converted into a wireless signal by the wireless collection module 14 and then transmitted to the external space.
The wireless receiver 16 located near the track receives the wireless signal transmitted by the wireless acquisition module 14 and outputs the wireless signal to the ground controller 18. The ground controller 18 can obtain the temperature information sent by the wireless acquisition module 14, and then transmit the temperature information to an upper computer of a train monitoring center. Thus, after the upper computer receives the temperature information returned by the ground controller 18, the temperature condition of the axle 31 to which the temperature information belongs can be obtained. Because the temperature information is only transmitted back when the wireless acquisition module 14 passes near the track, effective axle 31 position information can be provided for an upper position through the temperature information, and the high-precision monitoring of the temperature and the position of the axle 31 of the moving train is realized. The ground controller 18 may send the temperature information to the upper computer in a wireless communication manner, or may send the temperature information to the upper computer in a wired communication manner, which may be specifically determined according to the communication interface type of the ground controller 18.
In the train axle temperature detection device, the temperature sensor 12 is arranged on the bogie of the train, the wireless acquisition module 14 is arranged on the train, the wireless receiver 16 and the ground controller 18 are arranged near the track, when the train passes near the track, the wireless receiver 16 is in communication connection with the wireless acquisition module 14, receives the temperature information of the axle 31 passing near the track at present and outputs the temperature information to the ground controller 18. The ground controller 18 can further transmit the obtained temperature information to an upper computer of a train monitoring center, so that the temperature monitoring of the axle 31 of the automatic non-contact bogie is realized. Therefore, the external environment influence on the temperature monitoring of the axle 31 is greatly weakened, the detection point can be directly positioned along with the output time and the position of temperature information, the problem of low detection precision existing in the traditional axle temperature detection technology is effectively solved, and the purpose of greatly improving the axle temperature detection precision is achieved.
Referring to fig. 2, in one embodiment, wireless acquisition module 14 includes a microcontroller 142 and a transmitting antenna 144. The microcontroller 142 is electrically connected to the temperature sensor 12 for collecting temperature information. The transmitting antenna 144 is electrically connected to the microcontroller 142 for wirelessly transmitting the temperature information.
The microcontroller 142 may be a wireless microcontroller 142 device commonly used in the art, such as but not limited to a microcontroller 142 suitable for ZigBee (ZigBee) communication technology and 6LoWPAN (low speed wireless personal area network standard based on IPv 6) communication technology, belonging to a device having features of economy, high efficiency, ultra-low power consumption, and the like, and may autonomously collect temperature information in case of a sleep mode. The transmitting antenna 144 may be, but is not limited to, a microwave antenna or a radio frequency antenna, and the specific type may be selected according to the need of wireless transmission and reception. The microcontroller 142 and the transmitting antenna 144 may be directly connected by a wire, or may be connected by a wire on a Printed Circuit Board (PCB), i.e., integrated package, as long as reliable Circuit connection and signal transmission thereof can be achieved.
Specifically, after the signal output by the temperature sensor 12 enters the microcontroller 142, the microcontroller 142 may perform corresponding signal processing, such as conventional analog-to-digital conversion, signal filtering before being sent to the transmitting antenna 144, encoding, frequency conversion, and the like, to form a wireless signal that can be output to the transmitting antenna 144 for wireless transmission. The transmitting antenna 144 wirelessly transmits the temperature information of the axle 31 by transmitting a wireless signal to an external space. Thus, when the transmitting antenna 144 passes through the set area of the track, the wireless receiver 16 receives the wireless signal transmitted by the transmitting antenna 144 to receive the temperature information of the axle 31.
Through the microcontroller 142 and the transmitting antenna 144, the temperature information of the axle 31 is wirelessly transmitted to the wireless receiver 16 in real time in the process of train advancing, the adoption of a traditional infrared axle temperature monitoring system or a vehicle-mounted axle temperature sensing monitoring system is avoided, the high-precision detection of the axle temperature is realized, and meanwhile, the structure of the simplified axle temperature detection device is reduced, and the detection cost is also reduced.
In one embodiment, the transmitting antenna 144 is an active electronic tag. The active electronic tag is used for wirelessly transmitting temperature information and number information corresponding to the temperature sensors 12 one by one.
It can be understood that, in the present embodiment, an active electronic tag widely used in the art may be used as the transmitting antenna 144, so that the number carried by the active electronic tag may be used to represent the number of the axle 31 on which the temperature sensor 12 is located, that is, the axle 31 is encoded.
Specifically, by using an active electronic tag as the transmitting antenna 144, the purpose of assigning a number to the axle 31 can be achieved by assigning the number (i.e., RFID number) of the active electronic tag in advance. Thus, after the temperature sensor 12 monitors the axle temperature of the axle 31, the obtained temperature information is transmitted to the outside through the active electronic tag, and is transmitted to the wireless receiver 16 together with the serial number of the active electronic tag. Therefore, the wireless receiver 16 can obtain the temperature information and the corresponding number information after receiving the radio frequency signal of the active electronic tag. The upper computer can acquire the temperature information of the axle 31 through the serial number information, and can identify the serial number of the axle 31 to realize the positioning function of the axle 31.
Through the application of the active electronic tag, the upper computer can receive the temperature information of the axle 31, and meanwhile, the positioning of the axle 31 can be realized through the actual position information (namely, the number information) of the active electronic tag, so that the aim of detecting the temperature of the axle 31 with higher precision is fulfilled.
In one embodiment, wireless receiver 16 is an RFID receiving antenna. The surface controller 18 is an RFID reader.
Optionally, in this embodiment, the RFID receiving antenna may be used to receive the radio frequency signal emitted by the active electronic tag, and the RFID reader is correspondingly used to process the radio frequency signal and communicate with the upper computer, so as to transmit the obtained temperature information to the upper computer.
Specifically, after the RFID reader receives the radio frequency signal transmitted by the active electronic tag through the RFID receiving antenna, the number information of the axle 31 and the temperature information corresponding to the number information can be obtained from the radio frequency signal. The RFID reader may determine the axle 31 to which the currently received temperature information belongs by comparing the obtained number information with a pre-stored slave reference number (i.e., a pre-stored number of the axle 31). And then after the RFID reader transmits the temperature information and the corresponding serial number information to the upper computer, the upper computer can acquire the position of the axle 31 corresponding to the serial number information and the current temperature information of the axle 31, so that the real-time axle temperature detection and the axle 31 positioning of the axle 31 are realized, and the axle temperature detection precision is effectively improved.
Referring to fig. 3, in one embodiment, the microcontroller 142 is electrically connected to at least four temperature sensors 12 through a single bus. The temperature sensors 12 are provided on the four axles 31 of the two bogies, respectively. Wherein the two bogies are located on the same car of the train.
It will be appreciated that at least two bogies are included on any one railcar, and each bogie may include two axles 31. Therefore, at least one temperature sensor 12 for detecting the axle temperature of each axle 31 may be provided on each axle 31 in any one of the train cars. Correspondingly, each train carriage may be provided with a microcontroller 142 for respectively collecting the temperature information detected and output by each temperature sensor 12, so as to obtain the temperature information of each axle 31. It should be noted that the number of the microcontrollers 142 arranged on each train car may also be two or more, and specifically may be determined according to the number of the temperature sensors 12 and the number of the signal interfaces included in a single microcontroller 142.
Specifically, for any one train car, at least one temperature sensor 12 may be provided on each of the four axles 31, for detecting the axle temperature of each axle 31. Each temperature sensor 12 is electrically connected to the microcontroller 142 through a single bus to separately collect temperature information of each axle 31.
By the arrangement mode of the temperature sensor 12 and the microcontroller 142, the axle temperature of each axle 31 can be detected in real time, and meanwhile, the transmission reliability of temperature information is improved, so that the axle temperature detection precision in the advancing process of a train is further improved.
In one embodiment, the microcontroller 142 is also used to electrically connect an on-board monitoring system of the train. The vehicle-mounted monitoring system can be a running control system of the train or an independently arranged vehicle condition monitoring system. Optionally, the microcontroller 142 provided in each car of each train may also be connected to an on-board monitoring system of the train via a wire. In this way, during the running process of the train, the microcontroller 142 can also transmit the obtained temperature information of each axle 31 to the vehicle-mounted monitoring system, so as to realize the sharing of the temperature information of the axles 31. The train crew can monitor the temperature condition of each axle 31 in real time in the driving process through the vehicle-mounted monitoring system, so that the train crew can keep linkage with a manager of a train monitoring center conveniently, and the temperature monitoring efficiency of the axles 31 in real time is improved.

When the train passes by, the transmitting antenna 144 arranged on the train transmits the temperature information and the corresponding number information to the wireless receiver 16 near the track through radio frequency signals, and then the ground controller 18 transmits the obtained temperature information and the corresponding number information to the upper computer, so that the real-time monitoring of the axle temperature of the corresponding train bogie is realized.
In one embodiment, the ground controller 18 is disposed on the ground or on a track. It will be appreciated that in this embodiment, the ground controller 18 may also be located near the track and may be mounted on the ground or on the track. The ground controller 18 may be mounted adjacent to the track either directly to the ground or directly to the track, for example directly to the ties of the track, the web of the rail or the foot of the rail.
