Description

An RFID-based pole-frame meter box and its maintenance method

technical field

The invention relates to an agricultural pole frame type watch box, in particular to an RFID-based pole frame type watch box and a maintenance method thereof.

Background technique

In summer and autumn, when there is high temperature and little rain, crops are under great pressure of water shortage, and they experience a "drought battle" ranging from one to three months every year. However, in the case of extreme drought, serious problems often occur: first, the business volume of the "water-fetching" user's low-voltage industry expansion and new installation of electricity meters increases suddenly; second, there is a bottleneck in the installation location of the meter box. Taking risks in the face of interests, the phenomenon of hooked power stealing has become very common, resulting in increased line losses in low-voltage stations. Due to the limited power pole resources in the Taiwan area, the bottleneck has been reached. Some users did not meet the installation conditions during the on-site survey of new installations, and there was a risk of passive power theft. Hooking up to fetch water, because crops involve the economic interests of users and people's livelihood, it is difficult for the government and power supply to deal with it. The area line loss indicator was slumped. In order to avoid the occurrence of such situations, the power grid staff use the pole-mounted agricultural meter box to hang on the utility pole, and check the effect of the use of the pole-mounted multi-table agricultural meter box, so that in the case of the shortage of pole resources, the Installation of a large number of irrigation meters. The high temperature weather in summer is the most frequently used season for electric meters. Due to the large number of agricultural electric meters, the electric meters need to be turned on one by one for maintenance. However, since only two meter boxes can be installed on each utility pole, multiple utility poles are distributed in different areas. During maintenance, it is easy to have missed inspections and lack of inspections, resulting in certain safety hazards.

For example, a "a kind of agricultural discharge meter box" disclosed in the Chinese patent document, its announcement number 204228781U, includes a first sub-meter box and a second sub-meter box, and the two sub-meter boxes each include an independent box chamber, And the box door matched with the box room and connected to the box room, it can be seen that the entire meter box includes two independent box chambers and two independent box doors. In specific applications, each electrical component can be classified according to actual needs. , and install components of different types in different compartments separately, so that when the electrical components of one compartment need to be viewed or operated, and the corresponding compartment door is opened, the components in the other compartment are not exposed; and The two rotating shaft components realize the connection between the corresponding box door and the box chamber, which shares the load-bearing and reduces the burden compared with one rotating shaft component. However, when overhauling the meter box, the meter box in the area may still have a lack of detection and omission, but there is no prompt. Therefore, it is necessary to find a pole-mounted meter box that can prompt the staff when there is a lack of detection and missed detection.
