Problems solved by technology

However, these technological transformations still cannot effectively prevent the occurrence of theft
The material of the cover body is mainly replaced by metal cast iron with plastic or cement material, which makes the manhole cover worthless, but it still cannot prevent criminals from opening the manhole cover to steal underground cables
[0004] In terms of technology, there are also individual companies that have solved the problem of a single manhole cover anti-theft alarm, but the cost is too high, the cost performance is low, and there is no value for large-scale promotion and application
[0005] It is not difficult to study the anti-theft technology of manhole covers, the key is that the construction cost may be too expensive
Because the cost of an ordinary manhole cover is about 200-500 yuan, and the average cost of building an anti-theft system may reach several times the cost of the manhole cover itself, so there is no need for construction

Embodiment 1

[0035] refer to Figure 5 , the present embodiment consists of a manhole cover detector and a GSM alarm host, which are connected to the GSM alarm host through wired power supply and signal transmission. It is suitable for various communication cable manhole covers, power cable manhole covers, and gas supply pipe manhole covers that have the conditions for laying cables in ditch wells, but it is not suitable for sewer manhole covers. This embodiment is characterized by good reliability.

Embodiment 2

[0037] refer to Figure 6 , the present embodiment consists of a manhole cover detector, a power supply module, a magnetic induction charging module, a wireless transmitting module and a GSM alarm host. The manhole cover detector comes with its own power supply. When the manhole cover is closed, the manhole cover detector is in a dormant state to reduce power consumption. When the manhole cover is opened illegally, it will automatically wake up and enter the power supply state. The power consumption is supplemented by high-frequency magnetic field inductive charging. , to ensure that the self-provided power supply has been used underground for more than five years. The manhole cover detector is connected with the GSM alarm host through long-distance wireless transmission. The wireless transmission distance is 500-2000 meters in the open area. When the transmission distance is limited, the signal is transmitted to the GSM alarm host through the wireless relay. It is suitable ...

Embodiment 3

[0039] refer to Figure 7 , the composition of this embodiment is the same as that of Embodiment 2, but the wireless transmission distance is relatively short, which is about 20 meters. The signal is transmitted to the GSM alarm host through the cable. The cable can be laid under the ditch well, can also be laid in the nearby ditch well, or erected in the air, as long as the cable distance is within the wireless transmission distance. It is mainly considered that it is inconvenient to use wired methods for some trench wells, and the construction is difficult, so nearby trench wells and redundant cables in the air can be used. It is suitable for various types of cable manhole covers, gas supply pipe manhole covers and water supply and drainage manhole covers. The feature of this embodiment is that the cable laying method is flexible, and the on-site environmental resources can be effectively used.

Abstract

The invention discloses a wellhole and wellshutter security alarming system for power telecom engineering, relating to the technical field of security alarming systems of the power telecom engineering. The wellhole and wellshutter security alarming system for the power telecom engineering consists of a wellshutter probe and a GSM (Global System for Mobile Communications) alarming host, wherein the wellshutter probe is fixed on a well wall and connected with the GSM alarming host to monitor in real time through a wireless signal; and a master control/branch control centre is established when the plurality of roads and the wellshutters in a large area are concentrated to monitor and manage. By adopting flexible monitoring terminals, the system can select a mobile phone for monitoring less quantity of wellshutters as a terminal according to small road sections and small areas, can be also suitable for large-area construction in a mode of an alarming centre, or adopts the mobile phone to monitor and then uses a mode of a monitoring centre after integration so as to realize high cost performance of the anti-theft technology of the wellshutter.

Description

Technical field: [0001] The invention relates to the technical field of security alarm systems for power and telecommunication engineering, in particular to a security alarm system for shafts and manhole covers in power and telecommunication engineering. Background technique: [0002] All provinces and cities have various types of manhole cover facilities, which belong to eight major industries such as communication, water supply, and power supply. Because manhole covers are cast, cast iron can be sold for money. For a long time, some criminals have made a living by stealing manhole covers on urban roads and selling them as scrap iron. The lost manhole covers are everywhere, and it is difficult for the municipal department to replenish them in time. , As a result, accidents that lead to casualties and vehicle damage occur from time to time; some criminals will open the manhole cover to steal underground cables, causing damage to electrical equipment. Therefore, it is very i...
