Description

Technical Field

[0001] The present invention relates to a dual-circuit active-standby isolated coal mine safety monitoring system, in particular to a dual-circuit active-standby isolated coal mine safety monitoring system capable of avoiding shutdown of the entire system and ensuring normal operation of the system. Background Art

[0002] The current power supply for the coal mine safety monitoring system central station is mostly single-circuit mains electricity to the central station room, connected to the UPS, and then connected by the UPS to the server and network equipment cabinets and operating desks. In addition, the lightning protection measures are not perfect, the lightning protection of the server and network equipment cabinets is not in place, and the network lightning protection system is not installed as required in most mines.

[0003] This power supply method does not have enough redundancy. When the power supply system fails, it is very easy to cause power failure in the entire central station, thereby causing the monitoring system to shut down and causing major non-personnel accidents. Summary of the Invention

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A dual-circuit main-standby isolation type coal mine safety monitoring system, comprising a power distribution cabinet, a main monitoring cabinet, a standby monitoring cabinet, a main monitoring console, and a standby monitoring console;

[0007] The monitoring host cabinet includes a main server, a KVM switch, an intranet main switch, a main network gateway, a main external network switch, and a WEB server;

[0008] The main monitoring console includes provincial transmission host, monitoring host, ring network monitoring, bureau transmission host, and central ring network host;

[0009] The monitoring standby cabinet includes a standby server, an intranet standby switch, a standby network gateway, and a standby external network switch;

[0010] The monitoring console includes a monitoring standby machine, a central ring network standby machine, a local transmission standby machine, and a provincial transmission standby machine;

[0011] The power distribution cabinet is connected to the main monitoring cabinet and the main monitoring console respectively through the main UPS; the power distribution cabinet is connected to the standby monitoring cabinet and the standby monitoring console respectively through the standby UPS;

[0012] The power distribution cabinet is a dual-circuit automatic switching power distribution cabinet, which is connected to the main UPS and the backup UPS through automatic switching;

[0013] The power distribution cabinet is equipped with a three-level lightning protection module and a grounding protection module;

[0014] The main UPS and the backup UPS are both 6KVA, and the main UPS and the backup UPS form an uninterruptible power supply.

[0015] The present invention provides a dual-circuit primary-standby isolated coal mine safety monitoring system, which has the characteristics of avoiding system-wide shutdown and ensuring the normal operation of the system. The beneficial effects of the present invention are as follows: the three-level lightning protection module uses a network lightning protection module to achieve network lightning protection for the system; the grounding protection module ensures the safe operation of the distribution cabinet. When the power supply is abnormal, the leakage in the distribution cabinet is promptly diverted to the ground to protect the safety of personnel and equipment in the system;

[0016] The main UPS and backup UPS in the power distribution cabinet realize complete isolation of the power supply of the main and backup systems. When a fault occurs at any end of the system on the main UPS side, it will not cause the entire system to shut down. The power distribution cabinet will automatically cut off the main UPS and switch to the system on the backup UPS side to ensure normal operation of the system. BRIEF DESCRIPTION OF THE DRAWINGS
