Lock opening and closing remote signaling device for electric meter box

Abstract

The invention discloses a lock opening and closing remote signaling device for an electric meter box. The device comprises the electric meter box, wherein the outer wall of the electric meter box is fixedly connected with a coded lock, the inner side of the electric meter box is connected with a PCB, and the outer side of the coded lock is provided with a protection mechanism. According to the lock opening and closing remote signaling device for the electric meter box, the electric meter box is provided with an box opening and closing detection module, and the number and the time of opening and closing of the electric meter box are recorded in real time; meanwhile, the situation of damaging the electric meter box through abnormal means is alarmed through a magnetic field detection module,and the box opening detection module arranged in the electric meter box detects the opening and closing state of the electric meter box through detecting the state of a door contact arranged in the electric meter box; and when the state of the door contact changed from opening to closing or the box opening detection module judges that a metering box door is opened, a trigger signal is sent to a MCU, and then the MCU can record the corresponding time of box opening and closing on an upper computer through an encoding program according to the received signal and notify a worker through a messagemode.

Description

technical field [0001] The invention relates to the technical field of electric meter box opening and closing locks, in particular to remote signaling equipment for electric meter box switch locks. Background technique [0002] The meter box is mainly made of ABS engineering plastics, polycarbonate transparent pc material, DMC, and SMC by injection molding and pressing, and the size of the meter box is different. 1. The remote signaling equipment for closing the box lock is an auxiliary equipment for the standardized management of the marketing meter box, and it is installed on the door of the meter box. [0003] The problem of the abnormal switch box of the existing electric meter metering box on site is relatively prominent. Although there are management measures and management methods for the opening and closing of the metering box, there is no technical means to record the opening and closing of the metering box. The metering box is a protection As an important barrier ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the abnormal switch box of the existing electric meter metering box is relatively prominent. Although there are management measures and management methods for the opening and closing of the metering box, there is no technical means to record the opening and closing of the metering box. The metering box is an important barrier to protect the metering equipment. The opening and closing of the metering box must be carried out under the supervision of professional and technical personnel. Unauthorized opening operations not only have potential safety hazards in electricity use, but also use Insufficient of the risk of electrical equipment being damaged, provide remote signaling equipment for opening and closing locks in the meter box to achieve the purpose of protecting the safety of electrical equipment in the metering box, reducing loss and increasing efficiency, and having a good effect of protection and dust prevention
