Embodiment 1

[0038] see figure 1 , in the present embodiment, remote meter reading method comprises the following steps:

[0039] Step 101, allocate two public network numbers for each meter reading subsystem: one public network number is occupied by the system central station as the central station number; the other public network number is occupied by all meters connected to the subsystem in time-sharing, As a meter common number.

[0040] Step 102, at the central station of the system, assign different time windows to each meter connected to the subsystem. Meters may include water meters, electricity meters, gas meters, etc.

[0041] In this step, the time windows that can be set include two types: access time windows and ID time windows. Among them, the access time window is used by the newly connected meter, which is used to realize the access of the new meter to the meter reading subsystem, so as to obtain the relevant information of the ID time window assigned by the central stat...

Embodiment 2

[0055] In Embodiment 1, the time windows set by the system central station only include two types: access time windows and ID time windows, and each meter has its own relatively fixed ID time window. However, in some special cases, using a fixed ID time window to set rules is not flexible enough and may not meet usage requirements. For this reason, the second embodiment has the following improvements on the basis of the first embodiment: in addition to the access time window and the ID time window, the system central station also sets a plurality of random time windows, which are evenly distributed throughout the time, and the system center Stations are temporarily assigned to different meters as needed.

[0056] For example, when the system central station wants to take more detailed time measurement data of a certain user, it temporarily assigns a random time window to the user meter. In this way, the user meter not only opens the communication module in its own ID time wind...

Embodiment 3

[0060] In Embodiment 1 and Embodiment 2, the entire meter reading subsystem only needs two public network numbers, one for the system central station and one for all meters, so that the operating cost is kept to a minimum. However, in practice, when the number of meters is too large, if one public network number is not enough, the entire meter group can also be divided into multiple meter groups, and a public network number is assigned to each meter group. Multiple public network numbers are allocated, but the operating cost is still very low, but the efficiency of metering data collection is greatly improved.

Abstract

The invention discloses a remote meter reading system and method. The method comprises the following steps: distributing a public network number for all meters in each meter reading subsystem and taking the public network number as a public number of the subsystem; in each meter reading subsystem, setting an accessing time window by a system central station; meanwhile, distributing an only ID time window in the subsystem for each meter in the meter reading system; when each meter in each meter reading subsystem is accessed for the first time, communicating the meter with the system central station in the accessing time window so as to obtain only ID time window information in the subsystem; and after the first time of accessing, communicating each meter with the system central station in the corresponding ID time window by using the public network number of the meter of the subsystem through a mobile communication public network, and reporting metering information to the system central station. According to the remote meter reading system and method, large-batch remote meter reading can be realized by only occupying few, even two number resources, so that network resources are greatly saved and the meter reading cost is reduced.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a remote meter reading system and method. Background technique [0002] With the rapid development of our country's national economy, the improvement of people's living standards, and the continuous expansion of housing complete sets and commercialization, residents have higher and higher requirements for the surrounding environment of housing, the management quality of property departments, and the level of public service services. At the same time, it is becoming more and more obvious that the traditional manual meter reading method of the public service department does not adapt to the development of the society. It is difficult to read the meter and enter the house, there are many door locks, the labor intensity is high, the efficiency is low, the social problems are complicated, and the contradictions are great. The objective existence of problems such as these has caus...
