Detailed description of the preferred embodiment
In terms of hardware design, each data acquisition unit 110, the sub-controller unit 120 and the wireless communication unit a130 are regarded as a sub-node, and each sub-node comprises an attitude sensor, a microcontroller, a LoRa communication module, an RS232/RS485 communication module, a lithium battery and a solar cell panel.

Fig. 3 shows a schematic view of sub-node composition of a transmission tower inclination monitoring, early warning and management system based on LPWAN technology according to an embodiment of the present invention.
In the aspect of software design, the child nodes mainly achieve sensor information acquisition, information processing and communication. In order to reduce the power consumption of the node, the sub-nodes are designed to be in an intermittent working state, enter a dormant state after the data information is received, processed and transmitted, and are restored to the working state after a working instruction is received. Fig. 4 shows a flow chart of a main sub-node program of a transmission tower inclination monitoring, early warning and management system based on LPWAN technology according to an embodiment of the present invention.
As shown in fig. 4, after the system is initialized, whether the child node is in a working state is determined, if not, the power supply of the sensor is turned off, the LoRa module is put in a dormant state, and then a working instruction is waited; and if the module is in the working state, starting the attitude sensor to enable the microcontroller to receive and process the attitude sensor data, storing the data in a buffer area, and putting the LoRa module in the working state and transmitting the data according to a communication protocol.
The working mode of 'short-time working + long-time standby' ensures that the system can achieve the purpose of low-power consumption and long-time running while finishing transmission tasks.
In order to reduce the LoRa communication rate, increase the transmission power and meet the needs of large-scale and remote communication, a LoRa multi-hop communication program is added in the design of a sub-node, received data is processed by utilizing an improved LRU (least recent used) algorithm, the basic principle is that the received data is transmitted into a buffer with fixed space capacity once, and the principle that the data at the top of the buffer is latest and the data at the bottom of the buffer is earliest is always kept, when the space of the buffer is occupied by the uploaded data, the data at the bottommost of the buffer is replaced, and the processing steps are as follows: firstly, storing received data in a storage space; then, reading an effective data frame in the data according to the data head and the data tail; then, reading the data address and the target address of the effective data frame, and analyzing data information; and finally, storing effective information in the data information in a buffer area, and waiting for the input of next data. And after the algorithm processing is finished, modifying the target address in the sending buffer area and sending data.
The basic principle of the lru (least recent used) algorithm is to keep the space capacity of the buffer fixed, store the incoming data in the buffer in turn, and always store the newest data at the top of the buffer and the oldest data at the bottom of the buffer. When new data is added but the buffer is full, the modified lru (least recent used) algorithm of the present invention is applied to replace the data at the bottom of the buffer, the new data is put on top, and the data processing of the last element is completed before the replacement.
In the invention, the main node and the sub-nodes can simultaneously receive data of a plurality of LoRa modules, so that the data is processed by adopting an improved LRU algorithm, the error rate of transmission can be effectively avoided, and a large amount of storage space is saved. As an example, fig. 5 shows a working diagram of an lru (least recent utilized) algorithm improved in application of a transmission tower inclination monitoring, early warning and management system based on LPWAN technology according to an embodiment of the present invention.
