In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the embodiment of the application, the vehicle-mounted monitoring system is specifically arranged on a railway wagon. Railway wagons comprise a plurality of sections of vehicles. The train network 100 of the railway wagon onboard monitoring system as shown in fig. 1 comprises: a host 101 and a positioning device 102 which are positioned on the same section of the railway wagon, and a gateway 103 which is respectively arranged on each vehicle; the gateway 103 on each vehicle is bound to the host 101. Both the gateway 103 and the positioning device 102 are communicatively coupled to the host 101. It should be noted that fig. 1 only exemplifies 3 gateways 103, and each gateway 103 is exemplified by being communicatively connected with 3 sensors. The number of gateways 103 in actual use is related to the number of vehicles, and the number of sensors is related to the monitoring requirement, so the number is not limited.
As an example, the host machine 101 and the positioning device 102 are disposed on a first vehicle (hereinafter referred to as a first vehicle) behind a railway freight car locomotive.
The locating device 102 can locate the first vehicle and, given the location information of the fixed points along the path of the railway wagon, can determine the relative position of the first vehicle to each fixed point.
The host 101 is configured to receive the fixed-point arrival information sent by the positioning device 102 and send the fixed-point arrival information to each gateway 103. The fixed point arrival information indicates that the first vehicle in which the host 101 is located has reached the fixed point or the area near the fixed point. The host 101 can specify the position relationship between the first vehicle and the fixed point according to the fixed point arrival information, thereby triggering the vehicle where the gateway 103 is located to start data monitoring.
Each gateway 103 is used for sending fixed-point arrival information to a sensor on the vehicle, so that the sensor performs fixed-point monitoring to obtain monitoring data; each gateway 103 is also used to obtain monitoring data and forward it to the host 101. The sensor may be: a brake cylinder stroke sensor, a brake cylinder pressure sensor, a brake pipe pressure sensor, a coupler longitudinal force sensor, a vibration sensor and the like. Different sensors can monitor different types of data for the vehicle. Each vehicle is provided with a gateway 103 and a sensor, the gateway 103 and the sensor can communicate through Long Range Radio (LoRa) technology, and in addition, the gateway 103 and the host 101 can also specifically communicate through LoRa technology.
After receiving the monitoring data sent by each gateway 103, the host 101 may buffer the monitoring data, so as to upload the buffered monitoring data at a desired time.
In the embodiment of the application, two data platforms are involved, namely a first data platform and a second data platform. The first data platform can be also called as a fog platform, and the second data platform can be called as a cloud platform. For the above-mentioned originally monitored status data during the operation of the vehicle, the host computer 101 sends to the first data platform. Some sensors may also alarm based on the monitored abnormal data, and the host 101 is further configured to obtain sensor alarm data through the gateway 103 and send the sensor alarm data to the second data platform. Wherein the first data platform is located at a vehicle section, for example, a certain station where a train passes; the second data platform is located in the cloud end, and for example, the second data platform can be a unified monitoring platform and is used for monitoring alarm data of vehicles, overall planning of train operation conditions and making relevant data analysis work.
The train network that this scheme provided can possess and unite each vehicle and each platform satisfies the ability of demands such as train network deployment, network release, braking test, data receiving and dispatching to with data transmission data platform in order to realize remote data collection and to the whole car control of railway train, make on-vehicle monitoring system can be for the service of permutation railway freight car.
The functions of the host 101 are not limited to the above functions. For example, the host 101 may also cooperate with train inspectors to complete train networking, network disconnection, train total braking tests, and train short braking tests. The host 101 is also used for initializing and receiving networking information of the train inspection flat plate and the gateway 103 when the railway freight car is in full-train networking; and the host 101 is also used for receiving train inspection panel information and sending network disconnection information to the gateway 103 when the railway wagon is disconnected from the network. Wherein the train inspection panel is a panel computer controllable by train inspection personnel. The train inspection flat plate is provided with matched developed software and programs, and train inspection personnel can control the host 101 to complete related train inspection tests (not limited to braking tests) and control disconnection by operating the train inspection flat plate. When the network is disconnected, the host 101 may be in a sleep state, and in the sleep state, the host 101 may still receive the message sent by the column inspection panel and relay the network disconnection message to each gateway 103. The gateway 103 then forwards to the sensor of the vehicle in which it is located.

The mobile network transceiver device 205 is used for the host 101 to communicate with the second data platform because the second data platform is located far from the train. Referring to fig. 2, the memory 201, the LoRa transceiver 203, the WiFi transceiver 204, the mobile network transceiver 205, and the battery 207 in the host 101 are all connected to the processor 202.
