Problems solved by technology

[0004] In the existing technology, the time used by each node in the wireless sensor network is the time of the local clock chip. If it is not calibrated for a long time, deviation will occur. The longer the time, the greater the error will be.

Embodiment 1

[0033] A WSN information release device based on GNSS / NTP, characterized in that it includes a GNSS receiving unit 101, an NTP server unit 102, an information management and publishing unit 103 and an information display and environmental information collection unit 104; the GNSS receiving unit 101 It is sequentially connected to the NTP server unit 102, the information management and release unit 103, and the information display and environmental information collection unit 104 through data lines.

[0034] The information management and release unit 103 includes a data processing and storage unit 201 and an information sending and receiving unit 202; the NTP server unit 102 is sequentially connected to the data processing and storage unit 201 and the information sending and receiving unit 202 through data lines.

[0035]The information display and environmental information collection unit 104 includes an information collection unit 203, a data processing and storage unit 204, ...

Embodiment 2

[0039] A method utilizing the device described in embodiment 1 to realize the WSN information release of GNSS / NTP, the specific steps are as follows:

[0040] Step 1: GNSS receiving unit 101 receives the time information of the international standard time of GNSS, and transmits to the NTP server unit 102 through the data interface, and the time of the NTP server unit 102 is the international standard time;

[0041] Step 2: The NTP server unit 102 uses the NTP protocol to synchronize the time of the information management and release unit 103 to the international standard time, and the information management and release unit 103 forwards the international standard time information to each information display and environmental information collection unit 104, and the information The display and environmental information collection unit 104 displays the international standard time again; the information collection unit 203 collects environmental temperature and humidity monitoring...

Abstract

The invention relates to a device and method for publishing wireless sensor network information based on a global navigation satellite system / network time protocol (GNSS / NTP), belonging to wireless sensor network technologies. In the method, time of each node in a wireless sensor network is respectively adjusted into international standard time consistent with a main control center by utilizing the NTP to ensure accuracy on the time of each sensor node, and an information publishing and feeding back device is developed on the basis of the integration and used for effective information publishing, remote control, information feedback of each terminal and the like of a laboratory and other occasions.

Description

technical field [0001] The invention relates to a GNSS / NTP-based wireless sensor network information publishing device and method, which belongs to the wireless sensor network technology. Background technique [0002] With the rapid development of wireless sensor network technology, the application of wireless sensor network in real life is becoming more and more extensive. Tightness. [0003] At present, in computer and network applications, a relatively common time synchronization method is the NTP protocol, which is based on the IP and UDP protocol stacks in TCP / IP, and can also be used by many other protocol groups for distribution. A protocol for time synchronization between a remote time server and a client. The NTP protocol completely defines the structures, algorithms, entities and protocols used in the process of time synchronization, and has been widely used in computers and networks. At the same time, the development of GNSS also makes each terminal in practica...
