Embodiment Construction

[0027] figure 1 It shows the architecture diagram of the remote wireless meter reading system. refer to figure 1 As shown, the system 1000 includes a wireless meter reading terminal 1010 , a floor concentrator 1020 , a building concentrator 1030 , a cell data terminal 1040 , an accounting center 1050 , and a handset 1060 . The entire remote wireless meter reading system takes the accounting center 1050 as the central contact point, a plurality of cell data terminals 1040 (one is shown in the figure as an example) form a primary backbone network, and a plurality of building concentrators 1030 (shown in the drawing as an example) It shows that two building concentrators D1 and D2) form a secondary backbone network, and multiple floor concentrators 1020 (the drawing shows two groups of floor concentrators A1-A3 and B1-B3) form a tertiary backbone network, The wireless meter reading terminal 1010 serves as the bottommost contact point. The entire network constitutes a micro-cel...

Abstract

The invention relates to a data collection method for remote wireless meter reading system. The remote wireless meter reading system comprises a wireless meter reading terminal for sending data, a data terminal for receiving data and accessing a front computer of an accounting center, and a concentrator for relaying data between the wireless meter copying terminal and the data terminal. The data collection method comprises that: the wireless meter reading module uploads data at fixed time in each day and backups data, and after the failure of data upload, uploads data again in a time interval; the concentrator automatically generates a meter data index list according to a preset meter ID list, searches and stores the data of the meter according to the index list, manages and maintains the storage device; the data terminal obtains the meter reading data of each day, collects and backups the data, and periodically reports the meter reading data to the front computer.

Description

technical field [0001] The invention relates to the field of wireless meter reading, in particular to a data collection method for a remote wireless meter reading system. Background technique [0002] With the continuous improvement of people's living standards, ordinary people have put forward higher requirements for the living environment; encouraged by government policies, home intelligence has developed rapidly. As a link in the intelligent industrial chain - intelligent meter reading system has also been vigorously developed. The traditional manual meter reading method is time-consuming and laborious, and its accuracy and timeliness cannot be guaranteed, which no longer meets the needs of social development. This also puts forward higher requirements for meter reading, so a long-distance meter reading scheme is proposed. [0003] Wireless meter reading system in the prior art, such as my country's patent No. 96202204.7, discloses a multi-user gas, electricity, and met...
