Problems solved by technology

[0004] 1. After the terminal device detects 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 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 has no effective solution for how to report the power supply status of the meter in a timely and accurate manner and at the same time ensure the stability of the meter reading network after the power supply of the meter is abnormal.

Embodiment 1

[0052] This embodiment is based on the above-mentioned prior art, and describes a method for reporting the power supply status of an electric meter with a transparent transmission function provided by the present invention from the perspective of an electric meter, such as image 3 , which is a flow chart of a method for reporting a power supply status of an electric meter with a transparent transmission function, and the method for reporting the power supply status includes the following steps:

[0053] S101. Receive a heartbeat monitoring packet, where the heartbeat monitoring packet includes a power supply status flag for indicating the power supply status of the ammeter;

[0054] S102. Modify the corresponding power supply state flag bit of the electric meter in the heartbeat monitoring packet according to the current power supply state of the electric meter, and send the modified heartbeat monitoring packet to the next device.

[0055] According to the above method, as long...

Embodiment 2

[0063] Based on the method provided in above-mentioned embodiment 1, see Figure 5 , this embodiment also provides a schematic diagram of a power supply status reporting device for an electric meter with a transparent transmission function. As shown in the figure, the power supply status reporting device 200 includes a data receiving module 210 and a power supply status reporting module 220. The data receiving module is used for Receive a heartbeat monitoring packet, the heartbeat monitoring packet includes a flag bit for indicating the power supply state of the electric meter; the power supply state reporting module is used to report the corresponding power supply state of the electric meter in the heartbeat monitoring packet according to the current power supply state of the electric meter The flag bit is modified, and the modified heartbeat monitoring packet is sent to the next device.

[0064] According to the above device, as long as the electric meter receives the heartb...

Embodiment 3

[0068] See Figure 8 , this embodiment also provides a flow chart of a method for monitoring the power supply state of an electric meter, wherein the method for monitoring the power supply state of an electric meter is applied to a meter reading network composed of at least one concentrator and multiple electric meters with a transparent transmission function, so The method for monitoring the power supply state of the electric meter specifically includes the following steps:

[0069] S301. The concentrator sends a first heartbeat monitoring packet including power supply status flag bits for sequentially indicating the power supply status of each of the electric meters in the meter reading network;

[0070] S302. The concentrator receives the second heartbeat monitoring packet returned by each of the electric meters in turn responding to the first heartbeat monitoring packet, and determines each of the electric meters according to the power supply status flag bit in the second ...

Abstract

The invention provides a power supply state monitoring technology for a meter reading network and an ammeter thereof, aiming at solving the problem of how to accurately and rapidly report a power supply state of the ammeter. A working principle of the power supply state monitoring technology comprises the following steps: monitoring the power supply state of the ammeter by the ammeter; when the ammeter receives a heartbeat monitoring pack, modifying a corresponding power supply state flag bit of the ammeter in the heartbeat monitoring pack according to the power supply state of the current ammeter and sending the modified heartbeat monitoring pack to the next equipment. According to the power supply state monitoring technology provided by the invention, as long as the ammeter receives the heartbeat monitoring pack, the corresponding power supply state flag bit in the heartbeat monitoring pack is modified according to the power supply state of the current ammeter; then the modified heartbeat monitoring pack is transmitted to the next equipment connected with the ammeter, so that accurate reporting of the power supply state of the ammeter is realized.

Description

technical field [0001] The invention relates to the technical field of electric meter reading, in particular to a method and a device for reporting a power supply state of an electric meter. 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 that realizes the power-down monitoring of the electric meter, there are the following problems: [0004] 1. After the terminal device detects 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 alarm messages will lead to d...
