As described in the background art, the present inventors have found that the problem of scattered monitoring positions, discontinuous data, etc. exists in the monitoring system in the prior art, and found that the problem arises because the 5T system is a ground system, in which the infrared shaft temperature detection system (THDS) uses technologies such as optical, infrared remote sensing, information processing, communication networking, and automatic control, etc., and sets the ambient temperature as a reference, and detects the magnitude of infrared radiation emitted from each vehicle bearing by using an infrared detector in an infrared probe disposed at the track side, and converts the detected magnitude into a corresponding voltage signal. The higher the temperature of the bearing surface is, the higher the energy of infrared radiation is, and the higher the corresponding voltage value output by the infrared probe is, so that the purposes of detecting the axle temperature of the vehicle and finding out the hotbox are achieved, and the device has the characteristics of rapidness, accuracy and non-contact, and can automatically detect the axle temperatures of various types of vehicles in operation. And (5) alarming the train axle with the exceeding temperature rise through data comparison and analysis. The dynamic image detection system (TFDS) for truck operation faults adopts a high-speed continuous digital photographing technology, a high-capacity image data real-time processing technology and an accurate positioning technology, and utilizes a rail-side high-speed camera to dynamically detect hidden faults and common faults of the operation truck. The rail edge acoustic diagnosis system (TADS) for early faults of the rolling bearings of the trucks utilizes a rail edge noise acquisition array to acquire the noise of the rolling bearings of the moving trucks in real time, and the early faults of the rolling bearings of the trucks are discovered in time through data analysis. When the ground safety monitoring system (TPDS) for the running state of the truck is used, the dynamic parameters between wheel tracks are dynamically monitored by using the track testing system arranged on the whole railway linear section, so that the running state analysis and judgment of the truck are realized, the functions of wheel scratch and overload and unbalanced load monitoring are realized, the networking tracking alarm is implemented on the truck with poor running quality, the wheel tread scratch is forecast by forward train inspection, and the overload of the cargo is early warned. The passenger car operation safety monitoring system (TCDS) is used for comprehensively detecting the axle temperature, power supply, car doors, under-door power supply, fire, air conditioner, fireproof paint, basic braking system, bogie and vehicle dynamics, and mainly monitoring the hot axle accident, fire accident, power supply failure and braking system and running part failure of the passenger car. Obviously, except the TCDS, the ground monitoring is realized through the device arranged on the rail side, but the cost is generally considered, the monitoring device is not arranged on the whole section of track, but a set of monitoring device is arranged at intervals, so that the monitoring positions are scattered, the monitoring data are discontinuous, the TCDS cannot realize the functions of other detection systems, the original acquired data are directly transmitted to the ground through an antenna, the data quantity is huge, and the transmission has time delay, so that the timeliness of the monitoring is affected.
For the above reasons, the present invention provides a solution capable of providing more timely and accurate operation state monitoring,
In one embodiment, as shown in FIG. 1, there is provided a rail wagon operating condition monitoring system comprising:
the state detection module 100 is arranged at each monitoring point of the vehicle, and is used for collecting state data of the vehicle and performing edge calculation on the state data to obtain first analysis data;

The vehicle-mounted gateway 200 performs fog calculation on the first analysis data, further performs calculation analysis and data coupling to obtain second analysis data, so that the data volume can be further reduced, and the uploading efficiency to the server 400 can be optimized.

For example, the first analysis data is generated by the status detection module 100, the second analysis data is generated by the vehicle gateway 200, and the third analysis data is generated by the local gateway 300, where the second analysis data may be the same as or different from the third analysis data.

In one embodiment, the rail wagon operating condition monitoring system further comprises:
The mobile terminal 600 is configured to acquire and display the second analysis data transmitted by the in-vehicle gateway 200 or the third analysis data transmitted by the in-situ gateway 300.
The mobile terminal 600 includes, but is not limited to, personal computers, smart phones, palm top computers, wearable devices, and the like.

In one embodiment, the state detection module 100 includes more than one MEMS sensor distributed at each monitoring point of the vehicle, and is configured to collect state data of the vehicle and perform edge calculation to obtain first analysis data.
Considering that the traditional sensor has complex structure, large volume and easy damage, needs continuous maintenance and verification, is complex to install, and can not acquire detection data in time once damaged, so that the MEMS sensor can be adopted. MEMS are known collectively as microelectromechanical systems (Micro-ElectroMechanical System), which are smaller in size, up to a centimeter or even just a few micrometers thick, and are much smaller in thickness than conventional machines. The silicon-based material has excellent electrical performance, the strength, hardness and Young's modulus of the silicon material are equivalent to those of iron, the density is similar to that of aluminum, and the thermal conductivity is close to that of molybdenum and tungsten. By adopting the generation technology similar to an Integrated Circuit (IC), the mature technology and technology in IC production can be largely utilized to carry out mass production with low cost, so that the cost performance is greatly improved compared with the traditional mechanical manufacturing technology. The MEMS sensor, as a key device for acquiring information, plays a great role in promoting miniaturization of various sensing devices, and has been widely used in the fields of space satellites, carrier rockets, aerospace devices, airplanes, various vehicles, biomedical science, consumer electronics, and the like. The MEMS sensor is used for monitoring the state data of the railway wagon, has the advantages of small volume, high sensitivity and low power consumption, is convenient to install on the vehicle in a lossless manner, ensures the reliability of the monitored data, has certain computing capacity, can perform edge computing on the state data, further realizes the light weight of data transmission load, reduces the data transmission load pressure and realizes low delay.
In one embodiment, the MEMS sensor is a sensor supporting the LoRa wireless transmission protocol for transmitting the first analysis data to the in-vehicle gateway 200 or the in-situ gateway 300 via the LoRa wireless transmission.
LoRa is a low power consumption local area network wireless standard, in which low power consumption is generally difficult to cover a long distance, and long distance is generally high in power consumption. The LoRa is Long Range Radio, and has the biggest characteristic that the LoRa is farther than other wireless modes under the same power consumption condition, thereby realizing the unification of low power consumption and Long distance, and expanding the distance by 3-5 times compared with the traditional wireless Radio frequency communication under the same power consumption. If the transmission distance is 2-5Km in towns, the suburban area can reach 15Km. The operating frequency may be in the ISM band, including 433, 868, 915MH, etc. The modulation scheme is a variation of linear modulation spread spectrum (CSS) based on spread spectrum technology, with Forward Error Correction (FEC) capability, and one LoRa gateway can connect thousands of LoRa nodes. The transmission rate is generally several hundred to several tens Kbps, and the lower the rate, the longer the transmission distance. Therefore, the data volume is reduced after the edge calculation is carried out on the data by matching with the MEMS sensor, and the data transmission rate can be effectively improved.

The low-power consumption Bluetooth is an intelligent and low-power consumption Bluetooth wireless technology, and the intelligent degree is further improved by reducing the size, price and complexity of intelligent equipment. Conventional bluetooth has a problem in that the battery is rapidly exhausted and the number of times of connection and disconnection is frequent, so that frequent repeated pairing is required. Bluetooth low energy successfully addresses these issues. Bluetooth low energy goes from design to use, all with minimum power consumption as design target. To reduce power consumption, bluetooth low energy devices are in sleep mode most of the time. When an activity occurs, the device will automatically wake up and send a signal to the gateway, personal computer or smart phone. The maximum/peak power consumption is no more than 15 milliamps and the average power consumption is about 1 microamp. The power consumption in use is reduced to one tenth of that of conventional bluetooth. In less applications, a single button cell can maintain stable operation for 5 to 10 years. The modulation of bluetooth low energy technology is slightly different from that of conventional bluetooth technology. Bluetooth low energy piconets are typically based on a master device connected to a plurality of slave devices. In a piconet, all devices are either masters or slaves, but cannot be considered both master and slave. The master controls the communication frequency of the slave, and the slave can only communicate according to the requirements of the master. Compared with the traditional Bluetooth technology, a new function added by the low-power Bluetooth technology is a broadcasting function. By this function, the slave device can tell that it needs to send data to the master device. The broadcast message also includes an activity or measurement.
