Problems solved by technology

[0004] However, when downlink devices such as electric meters or collectors are powered off, they will stop working. The concentrator can only know that the above downlink devices have power down failures when they need to actively obtain data from the downlink devices.
This detection method makes the main station lose the ability to monitor the downlink equipment, and cannot perform maintenance operations in time, causing the downlink equipment to be powered off for a long time, which brings potential safety hazards

Abstract

The invention discloses power grid downstream equipment. The power grid downstream equipment comprises a downstream equipment main body, a broadband carrier wave module, a power supply module, a capacitor, and a wireless communication module; the broadband carrier wave module is connected with the downstream equipment main body, and is used for realizing data communication of the downstream equipment main body; the power supply module is connected with the downstream equipment main body and the broadband carrier wave module, and is used for supplying the downstream equipment main body and the broadband carrier wave module with electricity; the capacitor is connected with the power supply module, is charged when the power supply module is in operation, and is discharged when power down of the power sup[ply module is caused; the wireless communication module is connected with the capacitor, is provided with electricity and turned on in discharging process of the capacitor, and is used for wireless sending of stored power down information and basic information of the power grid downstream equipment. The beneficial effects are that: the working states of the power grid downstream equipment can be acquired by upstream equipment; maintenance is convenient; and potential safety hazard caused by long term power down is avoided.

Description

technical field [0001] The invention relates to the technical field of electrical communication, in particular to a power grid downlink device and a power grid management system. Background technique [0002] With the improvement of the carrier technology level, the power line carrier communication capability has been greatly developed. Its channel construction investment is low, the channel bandwidth is wide, the transmission rate is high, the transmission frequency band is not limited, the interference from the external power network is small, and no re-assumption is required. The network has a wide range of applications, and is the main means of communication for regional power networks and provincial power networks. [0003] At present, a specific application scenario of the power line carrier communication technology is a smart meter. In the power supply network, the power line not only undertakes the role of power supply, but also undertakes the role of data communica...
