This application relates to the field of wireless sensor network transmission technology, in particular to a clock synchronization method for a wireless sensor system based on UWB technology, a receiving end system and a transmitting end system. The method includes receiving an acquisition command at the receiving end RX; Time stamp T for the collection instruction; the receiving end RX sends the collection instruction to the transmitting end TX through the UWB wireless signal; the transmitting end TX sends the sampling synchronization signal to the sensor at equal time intervals after receiving the collection instruction; Based on the total delay time, the sensor acquisition time is synchronized; the system applies this method. The wireless sensor system clock synchronization method based on UWB technology, the receiving end system and the transmitting end system provided by this application are based on UWB technology, combined with simple delay calculation and high-frequency sampling to achieve clock synchronization, the clock synchronization accuracy is higher, and the timeliness of data collection.
Description
technical field [0001] The present application relates to the technical field of wireless sensor network transmission, in particular to a UWB technology-based wireless sensor system clock synchronization method, a receiving end system and a transmitting end system. Background technique [0002] The wireless sensor network is a network form formed by organizing and combining different sensor nodes in a free manner through wireless communication technology. The network setting is flexible, and the location of the device can be changed at any time. Compared with the wired sensor network, the advantage is that it can be set up quickly, not limited by external conditions, the network topology is highly adaptive, and the nodes are distributed in control and management, with good robustness and high security. [0003] Among them, the information collected by the sensor nodes is sequential, that is, the user needs to know the time and sequence of the collected events. Therefore, wi...
