Problems solved by technology

[0004] 1. After the terminal equipment monitors the power failure, it will directly report the power failure information. This method will conflict with the upload of data service information of the current normal working meter.
[0005] 2. When a large number of terminal devices are powered off at the same time, the centralized upload of power-off alarm messages will lead to disordered superimposition of signal data, especially in the meter reading network implemented by optical fiber
[0006] In short, the existing meter reading network does not have an effective solution in how to upload the fault information or power failure information of the meter in a timely and accurate manner after the meter fails or loses power, and at the same time ensures the stability of the meter reading network.

Embodiment 1

[0047] See image 3 , this embodiment provides a flowchart of a method for monitoring a power-down area in a meter reading network, as shown in the figure, and the specific implementation steps of the monitoring method will be described in detail below.

[0048] Step S101, when a meter in the meter reading network detects a power failure, each power-down meter sets the transparent transmission function to off, generates a power-down alarm message, and sends the power-down alarm message to Next device or meter.

[0049] In this step, if the power-down ammeter in the meter reading network receives the power-down alarm information, it will not be forwarded, that is, the received power-down alarm information will not be processed (only receiving and analyzing data packets, temporarily not generating new data packet); if the normal ammeter in the meter reading network receives the power-down alarm information, it will be transparently transmitted to the next device or ammeter acco...

Embodiment 2

[0070] See Figure 5 , this embodiment also provides a flow chart of a smart meter power-down alarm method, as shown in the figure, the smart meter power-down alarm method is applied to a smart meter implementing the method in the above-mentioned embodiment 1, which specifically includes the following step:

[0071] S201, when it is detected that the electric meter is powered off, set the transparent transmission function of the electric meter to an off state;

[0072] S202. Generate power-down alarm information and send the power-down alarm information to the next device or electric meter;

[0073] S203. After receiving the power-down alarm information sent by the previous device and sending the power-down alarm information to the next device or the electric meter after the first interval, set the transparent transmission function of the electric meter to an on state;

[0074] S204. After not receiving the power-down warning information sent by the previous device and sendi...

Embodiment 3

[0076] See Image 6 , this embodiment also provides a schematic diagram of a smart meter power-down warning device, the smart meter power-down warning device 300 is arranged on a smart meter in the meter reading network, and the smart meter power-down warning device 300 includes power-down monitoring Module 310, alarm information generation module 320, first power-down processing module 330 and second power-down processing module 340, the power-down monitoring module is used to set the transparent transmission function to the closed state when the power-off of the ammeter is monitored; The generation module is used to generate the power-down warning information and send the power-down warning information to the next device or the electric meter; the first power-down processing module is used to receive the power-down warning information sent by the previous device and send the power-down warning information to the next After the device or the electric meter finishes sending th...

Abstract

The invention provides a meter reading network as well as an intelligent electric meter thereof, and technical schemes of power failure warning and monitoring in power failure districts, which are applied to the technical field of meter reading maintenance of intelligent electric meters. The technical principle is as follows: a tail end electric meter and a starting end electric meter in a power failure district are enabled to send power failure warning information, and the power failure warning information is sent to a concentrator in the meter reading network in time; the concentrator can accurately locate the power failure district in the network according to the positions of the tail end electric meter and the starting end electric meter; when being uploaded, the power failure warning information does not conflict with the business data of the meter reading network. The meter reading network has higher network reliability.

Description

technical field [0001] The invention relates to the technical field of meter reading, in particular to a meter reading network, smart meters thereof, and a power-off alarm monitoring method and device for a power-off area. Background technique [0002] In the existing intelligent power meter reading system, it is necessary to monitor the electric meter in the meter reading system to prevent the accurate data collection from being unable to be completed after the electric meter fails or is powered off. [0003] In the prior art, there are generally the following power-down monitoring technologies for electric meters: [0004] 1. After the terminal equipment monitors the occurrence of a power failure, it directly reports the power failure information. This method will conflict with the upload of data service information of the current normal working meter. [0005] 2. When a large number of terminal devices are powered off at the same time, the centralized upload of power-off...
