Problems solved by technology

[0004] Method 1 has low inspection efficiency and heavy workload, requires a lot of manpower, equipment and funds, and the inspection time is limited; method 2 improves the inspection efficiency to a certain extent, but there are still the following problems: 1. This method is not an online monitoring method, does not have real-time information feedback, and is prone to delayed processing; 2. High-speed trains run fast, with a speed of 360km per hour, that is, 100m / s. 3. This method has problems such as low position accuracy of the falling sling

Embodiment 1

[0076] Such as figure 1 As shown, an online monitoring method for the shedding of a leaky cable sling includes the following steps:

[0077] A. Collect the location information of the spreader and store it by number; each spreader has a unique number;

[0078] B. Implant the RFID tag 1 on the spreader, correlate the information of the RFID tag 1 with the location information of the spreader and build the database of the spreader; since each RFID tag 1 has a fixed and unique code, the spreader and RFID Unique relationship between tags 1;

[0079] The specific process is:

[0080] b1: First place the RFID tag T i Implant spreader A i , RFID tag T i Has a unique fixed code, i is an integer;

[0081] b2: the RFID tag T i The coding information and the corresponding spreader A i associated with location information;

[0082] b3: storage of coded information and location information associated with step b2;

[0083] C. The RFID reader-writer transmits the RFID identificati...

Embodiment 2

[0122] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the 3 sections L of the leaky cable to be monitored MN The number of corresponding monitoring units is two, and the two monitoring units are respectively connected to the 3-section L of the leaky cable to be monitored MN The two ends of the leaky cable, that is, replace the matching terminal at the end of the 3-section leaky cable in the embodiment with the same monitoring unit as the first end of the 3-section leaky cable to be monitored. This setting method can effectively extend the length of the 3-section leaky cable that can be monitored. , which in turn can be applied to the monitoring of longer tunnels.

[0123] As one of the core technologies of the Internet of Things, RFID technology is widely used in our daily life. A general RFID system consists of a reader (including a radio frequency module), a device covering radio frequency signals (usually an antenna) and an RFI...

Abstract

The invention discloses an online monitoring method and system for falling off of a leaky coaxial cable hoisting tool. The monitoring method comprises the steps of numbering and storing information, implanting an RFID label on the hoisting tool, transmitting an RFID recognizing signal by an RFID reader-writer through a leaky coaxial cable, receiving the RFID recognizing signal through the RFID label and sending an RFID feedback signal, and screening the fallen-off hoisting tool through the RFID reader-writer based on the received RFID feedback signal. The monitoring system comprises the leaky coaxial cable hoisting cable for implanting the RFID label, monitoring units, field management units, a network management module and a communication chain, wherein the network management module is correspondingly connected to a plurality of field management units; and each field management unit is correspondingly connected to a plurality of monitoring units in the corresponding areas to be monitored. With the adoption of the method and system, the falling off position of the leaky coaxial cable hoisting tool within certain area can be accurately positioned; the monitoring accuracy is high; the monitoring range is wide; and moreover, the method and the system are applicable to monitoring of the leaky coaxial cable hoisting tool with high length under various situations.

Description

technical field [0001] The invention relates to the field of on-line monitoring technologies such as wireless communication and the Internet of Things technology, and in particular to an on-line monitoring method and system for the shedding of a leaky cable spreader. Background technique [0002] At present, with the rapid development of high-speed railway passenger dedicated lines, the usage of leaky coaxial cables and corresponding accessories (leaky coaxial cable spreaders, etc.) is also increasing. Leaky coaxial cable spreaders, referred to as leaky cable spreaders, are used intensively in tunnels, and a set needs to be installed every 1 to 1.3 meters. Due to the piston effect when the train is running in the tunnel, the installed leaky cable spreader is prone to loosening and falling off under the long-term fatigue vibration load, which will cause the leaky coaxial cable to fall off and cause safety hazards to the train operation; at the same time When the train passes...
