The alarm signal uploading device is simple in circuit, convenient in implementation and easy in modification and popularization of a communication agency station; and according to the uploading method, a concentrated monitoring system network platform of the existing communication agency station is utilized for implementing uploading of remote alarm signals, the network platform sharing is carried out on the originally-constructed concentrated alarm system, the system performance is stable and reliable and the reconstruction and the investment are avoided.

Description

technical field [0001] The invention relates to the field of communication equipment monitoring, in particular to a centralized alarm signal uploading device and method for a main distribution frame. Background technique [0002] The main distribution frame is the main connecting device for the line between the switch in the communication station and the outgoing trunk cable. The outside line may be struck by lightning, or collide with the high-voltage power line or the mains power line or induce high-voltage surges to cause damage to the switch. Therefore, in addition to the connection between the telephone user and the computer room, the main distribution frame must also protect against overvoltage and overcurrent. effect. At present, the overvoltage and overcurrent protection of the general distribution frame at home and abroad usually adopts the action of overvoltage and overcurrent protectors to protect the lines and equipment from the main distribution frame to the ma...

Problems solved by technology

[0010] Due to its own design principle, the external alarm system has irreparable shortcomings in the current network application:

When the external cable line conditions are complex and the space electromagnetic interference is serious, the detection signal accuracy of the monitoring module is poor, and it is difficult to set a suitable background alarm current threshold, resulting in frequent false alarms of the system, and the front-line operation and maintenance personnel are at a loss;

[0012] 2. The high failure rate of the monitoring module itself restricts the long-term stable operation of the system;

[0013] 3. The installation method of the monitoring module is complicated, and it is difficult for the operation and maintenance personnel to maintain and operate on site;

[0014] 4. The alarm system needs to be networked separately, the construction cost is high, the system reliability is poor, the newly built network platform is immature, and the cost of independent development is high, which is not conducive to the promotion and use of operators
