Embodiment 2

[0091] image 3 It is a flow chart of a method for detecting, locating and alarming a monitoring ring network fault provided by Embodiment 2 of the present invention. A type of fault that often occurs in the ring network is the disconnection of a single optical cable in the ring network, such as figure 1 As shown, the optical cables A, B, C, and D connecting each ring network switch may be disconnected. In this embodiment, the disconnection of the optical cable B connecting the second ring network switch 22 and the third ring network switch 23 is taken as an example to illustrate how the ring network positioning alarm device 7 detects and locates a single optical cable disconnection fault.

[0092] This embodiment can be based on the foregoing embodiments, and specifically optimize the operation of performing fault detection and fault location according to the received detection responses returned by each switch, which specifically includes the following steps:

Embodiment 3

[0101] Figure 4 It is a flow chart of a method for detecting, locating and alarming a monitoring ring network fault provided by Embodiment 3 of the present invention. The second type of failure that often occurs in the ring network is that the interface module of the ring network switch is abnormal. The interface module can be an RJ45 module. In this embodiment, the ring network switch is, for example, the AW3112 chip of Zhengwei Technology, which supports up to 6 substations, and each switch is equipped with 8 RJ45 modules, and each RJ45 module has an interface identifier. When a substation fails, the corresponding RJ45 module will be abnormal. Next, it will be specifically described how the ring network fault location alarm machine 6 detects and locates the fault.

[0102] Specifically, in the above embodiment, the operation of performing fault detection and fault location according to the received detection responses returned by each switch includes the following steps:...

Embodiment 4

[0109] Figure 5 It is a flow chart of a method for detecting, locating and alarming a monitoring ring network fault provided by Embodiment 4 of the present invention. When a single optical cable disconnection fault occurs in the ring network, if it cannot be detected and taken measures in time, a second breakpoint will occur, that is, a dual optical cable disconnection fault. When the two-way optical cable is disconnected in the monitoring ring network, it may cause large-scale gas data upload interruption, personnel positioning system data interruption, industrial control failure, etc., which will bury hidden dangers for safe production and may cause unpredictable Loss. Therefore, how to detect and locate the two-way fault is particularly important. In this embodiment, the disconnection of the optical cable B and the optical cable C is used as an example for illustration.

[0110] In this embodiment, the operation of performing fault detection and fault location according ...

Abstract

The invention provides a device, a system and a method for monitoring looped network fault detecting, positioning and alarming. The method comprises the following steps of: broadcasting and transmitting detection information to switches in a monitoring looped network by a looped network fault positioning alarm machine according to a set period; performing fault detection and fault positioning according to the received detection response returned by each switch; and alarming according to the fault detection and fault positioning result. According to the device, system and method for monitoring looped network fault detecting, positioning and alarming, a worker can timely know faults in the network and take corresponding measures according to the alarm information, the phenomenon that the fault points are eliminated through massive manpower is avoided, and the working efficiency is improved.

Description

technical field [0001] The invention relates to fault alarm technology, in particular to a monitoring ring network fault detection and positioning alarm device, system and method. Background technique [0002] In recent years, with the acceleration of digital and intelligent construction of underground application systems in coal mines, the application of optical fiber monitoring ring networks in mines has become more and more widely used. Monitoring ring networks are used to monitor gas, temperature, personnel and automatic control systems in underground mines. , in order to better understand the downhole environment and equipment operation, and ensure the safety and production efficiency of underground workers. [0003] Due to the complex and harsh conditions of the underground environment, the geographical location of the network equipment is scattered and the load is heavy, from the wiring of the backbone optical fiber of the ring network, welding, communication equipmen...
