Problems solved by technology

However, traditional wireless sensors are powered by batteries. Once the sensor battery is out of power, the sensor network cannot work.
Moreover, a lot of manpower and material resources will be consumed in the later battery replacement process, a large number of battery replacements will also cause environmental waste, and long-term replacements will also cause a lot of money waste

Embodiment 1

[0048] Example 1: An endless sensor network building power balance monitoring system, including several nodes disposed in the same building of the building or in the support surface of the bridge, the node is mainly due to the pressure sensor module, RF signal acquisition Module, network module composition, induction surface of the pressure sensing module collects building pressure information and transmits to the pressure sensor module, the pressure sensor module receives the electrical energy supplied from the RF signal acquisition module, and converts the pressure information into data, uploaded to the network over the network module The radio frequency signal acquisition module capacitance is less than the set threshold, and the pressure sensor module enters the sleep state, at which time the RF signal acquisition module collects and converted into electrical energy, when the electrical energy deposit reaches a high set threshold, the pressure sensor The module is converted in...

Embodiment 2

[0122] Example 2: Such as figure 1 The display is a smart pebble structure diagram, consisting of a pressure sensing module, a data transmission rod, a radio frequency signal acquisition module, and a pressure sensor module. The pressure sensing module induces the pressure information, and transmits the pressure sensor module by the data transmission rod, and the pressure sensor module converts the pressure information to data by the electrical energy supplied by the radio frequency signal acquisition module, and uploads to the routing network by the built-in antenna. The radio frequency signal acquisition module is less than a certain threshold, and the sleep state is entered into the sleep state to collect and convert to electrical energy. When the electrical energy deposit reaches a high threshold, the sleep state is converted into an active state, and data acquisition is performed.

Abstract

The time synchronization method for data transmission between nodes belongs to the field of information technology. In order to solve the problem that two nodes charged by radio frequency can be woken up synchronously, there are two situations between adjacent parent and child nodes: one is that the superframe of the child node is larger than that of the parent node. The superframe size of the node, the other is that the superframe size of the parent node is larger than the superframe size of the child node, the adjustment method is: change the size of the superframe in one node, and keep the size of the superframe unchanged in another node, In order to realize the time synchronization of the two nodes, the effect is to realize the synchronous wake-up.

Description

Technical field [0001] The present invention belongs to the field of information technology, which relates to a real-time monitoring system based on a building force based on a passive sensor network. Background technique [0002] In terms of building safety testing, the originally used X-ray method, vortex method, optical diagnosis, etc. of China are initially used, and the safety status of the overall building is judged by the detection of local buildings, but this detection method has a lot of disadvantages. . With the development of information technology, some people use optical fiber communication technology to detect remote buildings. However, the use area and performance of this method are limited. Afterwards, people start using wireless sensors to install the bridge structure to detect their health. However, the sensor is placed in the entire bridge structure. If the bridge structure is more small, the bridge structure is large, and the number of sensors that need to be ...
