The invention discloses an anti-theft alarming well lid and an anti-theft alarming method thereof. The anti-theft alarming well lid comprises a well lid outer frame, an inner cover, a microprocessor, a falling switch, a position switch, a relay and a sound-light alarm device. The falling switch and the position switch are arranged on the inner cover and connected with the microprocessor in parallel. The sound-light alarm device is connected with the relay in series. Induction signals of the falling switch and the position switch are utilized for controlling the relay through the microprocessor, and the sound-light alarm device is controlled by the relay to work. The method comprises the steps that the initial value of the falling switch and the initial value of the position switch are set and stored, microprocessor work modes are set and selected, and initializing is carried out; the well lid enters an anti-theft mode; when the falling switch and the position switch output the induction signals at the same time, the microprocessor sends control signals, the relay is powered on, the sound-light alarm device is powered on to send a sound-light alarm till manual intervention is achieved and the microprocessor is reset, the relay is reset and powered off, and the alarm is stopped. The well lid and the method have the automatic alarming function, the structure is simple, the cost is low, and achieving is easy.
Description
technical field [0001] The invention relates to the field of construction of municipal public facilities, in particular to an anti-theft alarm manhole cover and an anti-theft alarm method. Background technique [0002] With the acceleration of urbanization, the construction of municipal public facilities has developed rapidly. Cables in departments such as electric power and communication are mostly buried underground, and routine maintenance is carried out through the manhole cover, which also provides criminals with an opportunity to pry open the manhole cover to steal cables. Due to the expansion of the urban area, the wide distribution and large number of manhole covers have made supervision difficult, and the crime of stealing cables through manhole covers has become more and more rampant. These acts of theft have affected the normal functioning of the facilities and caused huge direct and indirect losses. Manhole cover cable anti-theft has become a huge problem that ...
