Method for conveniently and rapidly collecting module signal quality based on Wi-SUN communication technology

Abstract

The invention provides a method for conveniently and rapidly collecting module signal quality based on a Wi-SUN communication technology. The method comprises the following steps: enabling a reading controller with a Wi-SUN module to be consistent with the initial state of the Wi-SUN module to be tested; the reading controller and the Wi-SUN module to be tested are set to have the same PANID; the reading controller and the Wi-SUN module to be tested are networked through an MAC (Media Access Control) layer; the to-be-tested Wi-SUN module sends a broadcast Ping packet, the reading controller sends a Reply packet to the to-be-tested Wi-SUN module after receiving the Ping packet, and when the to-be-tested Wi-SUN module receives the Reply packet, the to-be-tested Wi-SUN module obtains a received signal quality RSSI (Received Signal Strength Indicator); and after receiving the Reply packet, the Wi-SUN module to be tested puts the signal quality RSSI in an Ack packet and sends the Ack packet to the reading controller. Based on the Wi-SUN communication technology, the safety of the data acquisition process is ensured, and the system has the advantages of being convenient to carry, high in networking speed, high in data acquisition efficiency, high in data acquisition correctness and the like.

Description

technical field [0001] The invention belongs to the field of smart grid communication, and relates to a signal quality acquisition technology of a Wi-SUN communication module in a power system, in particular to a method for portable and fast acquisition of module signal quality based on the Wi-SUN communication technology. Background technique [0002] With the vigorous development of the smart grid, Wi-SUN module, as an important way of wireless communication between the meter and the concentrator, has been widely deployed and used in the smart grid. It plays the role of connecting the power system concentrator and the smart meter. [0003] At present, the sending and receiving signal performance of the Wi-SUN module will seriously affect the communication success rate between the concentrator and the meter. In the normal networking environment of the Wi-SUN module, the MAC layer and the network layer of the slave node (NODE) ​​and the master node (ROOT) module need to be c...

Problems solved by technology

[0003] At present, the sending and receiving signal performance of the Wi-SUN module will seriously affect the communication success rate between the concentrator and the meter

In the normal networking environment of the Wi-SUN module, the MAC layer and the network layer of the slave node (NODE) ​​and the master node (ROOT) module need to be connected to the Internet at the same time to communicate normally. It takes about 3 to 8 minutes to connect to the Internet. , which seriously affects the mass production test of Wi-SUN modules

At present, the existing method of conventional network testing module signal quality takes a long time to operate, the process is complicated, and it is difficult to meet the current market demand.
