Problems solved by technology

[0002] At present, the most widely used wireless networking protocol is the ZigBee protocol, which adopts the meter-end self-organizing network method, which is well suitable for the self-organizing network (grid power supply) initiated by the meter-end side of the wireless meter, but for the use of batteries For wireless water meters or wireless gas meters powered by the ZigBee protocol, the power consumption will become a headache. In the low-power standby mode of ZigBee, 2 AA dry batteries can support the work of 1 meter6 ~24 months, in the working mode, the battery life is shorter, and there is no way to meet the requirements of more than 7 years of use

Embodiment

[0040] Embodiment: The present invention implements networking of wireless water meters for A cell. The wireless water meters in this residential area all adopt the wireless chip of Atmel Company's model XMEGA. The specific steps of networking of wireless water meters in this community are as follows:

[0041] Step 1, divide the wireless water meters in the residential area into regions;

[0042] Step 2, determine that the test result of the wireless signal strength analysis of this type of wireless water meter is between -35dBm~-85dBm as a relay meter;

[0043] Step 3, the concentrator reads all the meters in an area, and records the wireless signal strength information of the 0-level repeater meters that can be directly read;

[0044] Step 4, through the analysis of the wireless signal strength, find out the 0-level relay table with stable reading and reading, and sort according to the priority order of the signal strength from weak to strong;

[0045] Step 5, respectively ...

Abstract

The invention discloses a method and a system for networking wireless water meters or wireless gas meters. The method comprises the following steps: carrying out regional division on wireless water meters or wireless gas meters in some residence community; reading all meters in one region by a concentrator, recording wireless signal intensity information of all levels of relay meters capable of directly reading; finding out all levels of stably reading relay meters through the wireless signal intensity analysis, and sequencing according to the priority sequence from the weak signal intensity to the strong signal intensity; finding out the reading ranges of all levels of relay meters according to the sequence; and finishing the regional networking by the concentrator, networking the meters regionally by the concentrator, finally finishing the networking in the residence community, and managing the meters according to routing information. The method is completely opposite to a conventional meter end self-networking mode, the concentrator is adopted to help the wireless water meters or the wireless gas meters to network, and the power consumption required by networking is reduced greatly, so that the requirement that the wireless water meters or the wireless gas meters supplied with power by batteries are used for more than 7 years is met.
