Problems solved by technology

A power surge arrester cannot protect the base station power system and equipment from infringement within such a large range of lightning current changes
In addition, sometimes the lightning current will not damage the equipment immediately, but it can accelerate the aging of components and equipment and greatly shorten its life.
So far, it is difficult for relevant departments to keep abreast of the lightning strikes of unattended mobile communication base stations
However, the existing detection system cannot meet the purpose of lightning detection and protection. For example, the Chinese patent No. 99213057.3 discloses a power failure wireless system for power distribution rooms suitable for industrial and mining enterprises and unattended power distribution rooms in rural areas. Paging alarm device, including high-voltage phase loss detection circuit, power phase loss detection circuit, lighting power phase loss detection circuit, display circuit, emission control circuit, radio paging transmitter and radio paging receiver, when power phase loss occurs In the event of a fault, the electrician can be paged wirelessly to eliminate the fault in time to avoid damage to electrical equipment, and at the same time send a paging alarm to the regional power supply center to facilitate supervision and management
However, the above-mentioned equipment is difficult to be used in the lightning detection of the base station. At the same time, because it uses wireless paging alarm, its use in mountainous areas is limited.

Abstract

This invention relates to lightning strike monitor alarm system, which comprises strike signal collector, remote alarm controller and central receiving controller, wherein, the said collector can detect strike times of movable communication without human on spot, lightning current range of each lightning, time of strikes, power arrester working status. The remote alarm controller gets these information through connection circuit to get these information for process and send out warns to express the strikes to display on LCD and send the communication types through long line or telephone line or GMS to the central receiver machine of the local place. The central receiver sends warnings and displays on LCD to inform relative human for quickly process.

Description

technical field [0001] The invention relates to a lightning strike detection and remote alarm system used in places such as unattended mobile communication base stations. Background technique [0002] With the development of mobile communication and radio and television technology, the number of mobile communication systems, wireless paging systems, satellite mobile communication systems, radio stations and television stations is increasing. Many base stations (differential turntables) are an important part of these systems. Usually these places are manned, unattended, or even unattended. Mobile communication base stations generally include equipment such as transceivers and antennas, and are installed at high altitudes. Therefore, it has a high probability of being struck by lightning, and once the lightning strike causes equipment damage, the economic loss will be huge. The power supply system of the mobile communication base station is one of the main channels for ligh...
