[0004] Therefore, the technical problem to be solved by the embodiments of the present invention is that the meter reading equipment in the prior art uses the RS485 communication method to read the readings of the electric energy meter, and the reading process is relatively complicated, resulting in increased use costs and waste of resources
[0005] Another technical problem to be solved by the embodiment of the present invention is that the meter reading equipment in the prior art uses RS485 communication to collect data because it cannot transmit communication commands and cannot analyze the communication commands supported by the electric energy meter, resulting in a reduction in its reading efficiency.

Embodiment 1
[0049] This embodiment provides a remote infrared meter reading method, which is applied to infrared meter reading equipment, such as figure 1 shown, including the following steps:
[0050]S1, establish connection with server, send heartbeat information to server; Wherein, because this step adopts GPRS communication mode, be used for communicating with server; This GPRS communication mode uses GPRS communication module to establish connection relationship with server based on TCP-IP agreement, this At this time, the GPRS communication module acts as a client and sends heartbeat information, that is, heartbeat frames, parameters such as the IP address and port number of the remote server.
[0051] S2. Receive the preset reading address and preset electrical parameter instructions returned by the server; because as an implementation method, the preset electrical parameters include: demand, peak-level and valley-time electric energy, three-phase unbalance, invalid energy consumpt...
Embodiment 2
[0063] This embodiment provides a remote infrared meter reading device, such as image 3 As shown, including the following units,
[0064] The first sending unit 31 is configured to establish a connection with the server and send heartbeat information to the server;
[0065] The receiving unit 32 is used to receive the instructions of the preset reading address and the preset electrical parameters returned by the server;
[0066] The obtaining unit 33 is used to obtain the current reading data according to the instructions of the preset reading address and the preset electrical parameters;
[0067] Judging unit 34, for judging whether the current reading data contains preset electrical parameters, if not, then according to the current reading data, obtain the data of preset electrical parameters;
[0068] The second sending unit 35 is configured to send data of preset electrical parameters.
[0069] As an implementation, the remote infrared meter reading device in this embo...

Abstract
The invention discloses a remote infrared meter reading method and a remote infrared meter reading device. The remote infrared meter reading method comprises the following steps: establishing a connection with a server, and sending heartbeat information to the server; receiving commands of a preset reading address and a preset electrical parameter which are returned by the server; acquiring current reading data according to the commands of the preset reading address and the preset electrical parameter; judging whether the current reading data contains the preset electrical parameter or not; if not, acquiring data of the preset electrical parameter according to the current reading data; sending the data of the preset electrical parameter. After the scheme is adopted, the remote infrared meter reading method can be used for enabling the reading device to rapidly analyze the current data read from an electric energy meter, so that the electrical parameter data needed by a user can be obtained; furthermore, the method is also capable of analyzing and studying infrared communication commands, thus acquiring the communication commands supported by the electric energy meter, and preventing the infrared communication commands, which are not supported by the electric energy meter, from being sent for a plurality of times; therefore, the reading time is shortened, and the reading efficiency is increased.
Description
technical field [0001] The invention relates to the technical field of electric energy meters, in particular to a remote infrared meter reading method and device. Background technique [0002] With the intelligent transformation of the national power grid and the response to national energy conservation and emission reduction, the State Grid collects the data information of the electric energy meter and transmits the data information through remote control, so it is inseparable from the necessary meter reading tools, generally using remote meter reading equipment Copy or collect the user's electricity consumption information to strengthen the user's electricity consumption management. [0003] The structure of remote meter reading equipment currently on the market is relatively complicated. Generally, RS485 and power line carrier are used to network to collect energy meter information. Because this method requires a large amount of engineering and complicated wiring, the cur...
