Embodiment 1

[0061] see figure 1 , figure 1 It is a schematic flow chart of Embodiment 1 of the remote meter reading method of the present invention.

[0062] In embodiment 1, the present invention provides a kind of remote meter reading method, and it comprises the steps:

[0063] Step S10, the master meter establishes a communication connection with the slave meters within the coverage of the same wireless network, and obtains an address relationship mapping list.

[0064] The wireless network in the present invention includes WIFI (Wireless Broadband). The main meter and the slave meter in the present invention are within the coverage of the same WIFI.

[0065] In the present invention, the master meter and the slave meter include an electric energy meter, a cold water meter, a hot water meter, a drinking water meter, a heat meter or a gas meter.

[0066] Step S11 , the master meter acquires a master meter data frame, and receives the slave meter data frame of the slave meter thro...

Embodiment 2

[0074] see figure 2 , figure 2 It is a schematic flow chart of Embodiment 2 of the remote meter reading method of the present invention.

[0075] In Embodiment 2, the basic steps are basically the same as those in Embodiment 1 above, except that the step S10 includes:

[0076] Step S20, the slave meter searches for the master meter in the same wireless network.

[0077] The slave meter sends a signal to the master meter in the same wireless network. When the master meter receives the signal, it feeds back a response signal to the slave meter, which means that the slave meter has searched for the master meter.

[0078] Step S21, when the master meter is found, the slave meter sends a slave meter data frame to the master meter, the slave meter data frame includes slave meter address information, and the master meter Contains the list of initial address relationship mappings.

[0079] In step S22, the master meter obtains a comparison result between the address information ...

Embodiment 3

[0091] see image 3 , image 3 It is a schematic flow chart of Embodiment 3 of the remote meter reading method of the present invention.

[0092] In Embodiment 3, the basic steps are basically the same as those in Embodiment 1 above, except that after the step S12, it includes:

[0093] Step S30, the master station server obtains a data table of communication connections between a slave meter and a plurality of master meters according to all address relationship mapping lists, and the data table includes the communication between the slave meter and each master meter strength information.

[0094] Step S31, the master station server determines the master meter with the strongest communication strength with the slave meter according to the communication signal strength information.

[0095] Step S32, the master station server sends a control instruction to the remaining master meters in the data table, and controls the remaining master meters to disconnect the communication ...

Abstract

The invention discloses a remote meter-reading method which comprises the following steps: establishing communication connection between a master meter and a slave meter in a same wireless network coverage to obtain an address relationship mapping list; acquiring a master meter data frame by the master meter and receiving a slave meter data frame from the slave meter by virtue of a wireless network; and sending the master meter data frame, the slave meter data frame and the address relationship list to a master station server by the master meter through a long-distance communication network. The invention further discloses a remote meter-reading system which realizes the remote meter-reading method. According to the method disclosed by the invention, the slave meter data frame of the slave meter is received by the master meter and the master meter data frame and the slave meter data frame are sent to the master station server through the master meter, so that the line pavement problem of the existing centralized meter reading manner is simplified.

Description

technical field [0001] The invention belongs to the technical field of meter reading equipment for meters, and in particular relates to a remote meter reading method and a remote meter reading system. Background technique [0002] With the advancement of science and technology, the popularization of computers and the continuous reduction of the cost of electronic equipment, the centralized meter reading technology has been used in the power industry for more than ten years, but all current centralized meter reading methods are the main station server. The command is sent to the concentrator device, the concentrator device sends the data to the collector, and the collector transmits the data to the final device ----- the meter. After the meter receives the instruction and analyzes it, the processed data Then return to the main station server one by one. [0003] The existing centralized meter reading method has led to the following aspects of the line laying of the centraliz...
