Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a micro-energy self-acquisition MEMS sensing pre-storage system of the Internet of Things. Background technique [0002] WSN (Wireless Sensor Network, wireless sensor network) is mainly composed of three parts: WSN node, WSN gateway and server. The main functions of the WSN node are: connect the sensor to the devices to be monitored in space, monitor the devices to be monitored through the sensors, and send the monitored data to the WSN gateway wirelessly, and the WSN gateway is connected to the server through wired or wireless methods , the server processes, analyzes and displays the data uploaded by the WSN gateway, so that operators can monitor the devices connected to the sensors distributed in different areas in real time. [0003] With the rapid development of wireless communication and low-power embedded technology, WSN is widely used in various fields such...

Problems solved by technology

[0004] In the prior art, WSN nodes are mainly powered by batteries with limited energy. Due to the large number of WSN nodes, wide distribution areas, and usually complex application environments, when the batteries of WSN nodes are exhausted, the cost of replacing batteries for WSN nodes very high

Therefore, in order to solve this technical problem, there has been a scheme in which the DC stabilized power supply generated by AC power conversion supplies power to WSN nodes, but this scheme has the following two problems: (1) Each WSN node needs a long power supply line The cable is connected to the power supply. In terms of specific implementation, the workload of installing the power supply cable is still very large, and the cost is relatively high; (2) Due to the large size of the power supply module and the complicated line connection, it is easy to modify the WSN node data. Transmission produces greater interference, which increases the error rate during data transmission
