Problems solved by technology

[0002] As we all know, cable wells are built for the convenience of construction cable laying and line maintenance for operation and maintenance personnel. When the power line in the cable well is short-circuited, it is very easy to cause fire. Some cables are not all flame-retardant materials, which are easy to be damaged Ignition, once a fire breaks out in the cable shaft, the signal lines of each system in the cable shaft will be burned, which will inevitably cause a large area of ​​important system paralysis and a large amount of data loss, thus causing immeasurable huge losses to the power company

Embodiment 1

[0028] In the embodiments of the present invention, see figure 1 The temperature sensor module 101 is one or two temperature sensors PT100 installed in each cable well. They can collect the temperature data of the cable in the well in real time, and then connect to the temperature acquisition module 102 (KL-M4542B) through the RS485 interface. ), and then collectively transmit it to the intelligent acquisition module 103 through the temperature acquisition module 102. The intelligent acquisition module 103 can be an intelligent collector, which performs comprehensive analysis and processing on the collected temperature data on the temperature monitoring platform. Specifically, the temperature monitoring platform is the terminal monitoring module 104, which can be implemented by an application software installed in a PC. The temperature monitoring platform system platform can be deployed in an intranet or a local area network through the TCP / IP protocol. The administrator or on du...

Embodiment 2

[0030] See figure 2 Those skilled in the art can understand that the optical fiber temperature sensor 201 has the characteristics of explosion-proof, flame-proof, anti-corrosion, and anti-electromagnetic interference, and is safe to use in harmful environments, realizing real-time and fast quasi-distributed temperature measurement and positioning, and can also have Program-controlled alarm function.

[0031] The optical fiber temperature sensor in the embodiment of the present invention is mainly distributed in the cable well, and the installation of the optical fiber temperature sensor should be completed in the shortest possible time. First install the optical fiber sensor into the cable connector of the cable well, and then complete the protection, series connection, and wiring of the sensor; the single-core optical cable and a 36-core optical cable are respectively welded through the optical cable splice box, and connected to the Control room to realize online monitoring.

Embodiment 3

[0037] The embodiment of the present invention also provides a cable well temperature detection method, the method includes the steps:

[0038] 301. Obtain the temperature data value of the preset position of the cable well through a preset temperature sensor;

[0039] 302. Obtain a digital signal corresponding to the temperature data value, and send it to a terminal monitoring module.

[0040] 303. When the terminal monitoring module determines that the temperature data value is greater than a preset range, perform a temperature alarm.

[0041] Further, the preset position of the cable well is a cable well connector.

[0042] It should be noted that the temperature sensor PT100 or the optical fiber temperature sensor is used in the embodiment of the present invention to collect the temperature value of the preset position of the cable well. Specifically, it can be the temperature value of the cable well connector, or the temperature sensor can be set in the cable interlayer. In the po...

Abstract

The invention discloses a cable well temperature detection system and method. The system includes temperature sensing modules used for collecting the temperature inside a cable well through at least one temperature sensor and sending collected temperature values to temperature collecting modules, the temperature collecting modules connected with the temperature sensing modules and used for receiving the temperature values collected by the temperature sensing modules, an intelligent acquisition module used for receiving temperature data sent by the at least one temperature collecting module, carrying out analog-to-digital conversion on the temperature data and sending the temperature data to a terminal monitoring module, and the terminal monitoring module used for receiving and displaying the temperature data in the form of digital signals sent by the intelligent acquisition module. By implementing the embodiments of the invention, effective monitoring of the temperature in a cable wellis realized, and the safety of the facility and building where the cable well is located is ensured.

Description

Technical field [0001] The invention relates to the technical field of cable well temperature detection, in particular to a cable well temperature detection system and method. Background technique [0002] As we all know, cable wells are built for the convenience of construction cable laying and line maintenance by operation and maintenance personnel. When the power cord in the cable well is short-circuited, it is very prone to fire. The sheathing materials of some cables are not all flame-retardant materials and are easily affected. If a fire occurs in the cable well, the signal lines of the various systems in the cable well will be burned out, and a large area of ​​important systems will be paralyzed and a large amount of data will be lost, which will cause immeasurable losses to the power company. At the same time, the dense smoke produced by the burning of these materials will contain a lot of harmful gases. [0003] Since the cable well is connected from top to bottom, just l...
