In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The train buffer structure state monitoring system with low power consumption designed by the invention is only used for monitoring the operation state of the freight train buffer in the embodiment, but is not limited to be suitable for monitoring the operation state of the freight train buffer and can also be suitable for monitoring the state of the passenger train buffer.

The sensor module comprises a combination of multiple sensors, and the sensor types are specifically selected according to the monitored object. For example, when the structural state of the freight train buffer is monitored, the sensor module adopts an acceleration sensor, a strain sensor and a distance measuring sensor, the acceleration sensor, the strain sensor and the distance measuring sensor are coupled together, and the state information of the monitoring structure is obtained through comprehensive measurement.
All sensors in the sensor module are connected with the microprocessor, and detected state information is input into the microprocessor.
The communication module adopts a wireless communication mode, in the embodiment, a Bluetooth 5.0 module is adopted, and the communication module transmits the acquired state information to a gateway or an upper computer; the gateway stably and high-speed acquires data through Bluetooth 5.0, the data is stored in the gateway in a binary form, the storage space of the gateway is 256 Mm, and the data is stored in a dat suffix format file. If data is collected once in two hours, the year round data can be stored. The data storage adopts cyclic storage, and when the storage space is full, the new data replaces the old data.
In the system, the power module is used for respectively providing electric energy for the microprocessor and each sensor in the sensor module, and the system is used for on-line monitoring of a train buffer structure with a complex structure and a small operation space, so that the power module adopts a lithium polymer battery with small volume and strong cruising ability.
According to the characteristics of the monitored object of the system, the system is awakened and dormant by setting the triggering condition and the dormancy condition of the sensor in the sensor module.
The schematic diagram of the structure of the train buffer is shown in fig. 2, and the system is arranged at the corresponding position of the train buffer when monitoring the running state of the train buffer, namely, the detection end of each sensor is contacted with the train buffer.
Firstly, setting a trigger threshold R of an acceleration sensor, wherein when the acceleration sensor is not triggered, the acceleration sensor always carries out threshold sensing and motion acceleration measurement, at the moment, the working current of the acceleration sensor is very small, and the acceleration sensor is in a low power consumption mode; at the moment, the acceleration sensor does not wake up the buffer structure state monitoring system, and other sensors, the microprocessor and the communication module in the whole buffer structure state monitoring system are all in a dormant state, so that the power consumption of the whole structure state monitoring system is extremely low.
The flow chart of the structure state monitoring system is shown in fig. 3, and when the acceleration change of the buffer structure reaches the trigger threshold R, it indicates that the motion state change of the buffer structure is large (the corresponding acceleration value is large), the acting force borne by the buffer structure is large, the damage probability of the buffer structure is large, and the buffer structure state needs to be monitored; triggering the acceleration sensor, wherein the acceleration sensor triggers to wake up the buffer structure state monitoring system, namely the microprocessor controls the strain sensor and the distance measuring sensor to start to acquire state information corresponding to the structure under the triggering of the acceleration sensor, and then the microprocessor stably transmits all the acquired state information to the gateway at a high speed through Bluetooth 5.0; and the monitoring personnel judges the state of the structure according to the information acquired by each sensor.
When the acceleration value of the buffer structure does not reach the trigger threshold value R, the buffer structure is in a static state or the motion state changes very little at the moment, the acting force borne by the buffer structure is small at the moment, the damage probability of the buffer structure is small, and the buffer structure state does not need to be monitored, so that the acceleration sensor is recovered to a low power consumption mode to continuously perform threshold value sensing, and the whole buffer monitoring system is recovered to a dormant state.
The structural state monitoring system can keep extremely low energy consumption when not monitoring, so that the cruising ability of the whole structural state monitoring system can be improved, the connection with a power supply is not required to be kept through a circuit, and long working time can be achieved only by adopting a small battery; meanwhile, the miniaturization design of the structure state monitoring system can be realized.
