Embodiment 1

[0036] The utility model relates to an underground pipe network early warning system for tap water pipelines, which includes a control center connected with two early warning lines. The early warning line is used to be laid in the soil layer higher than the depth of the underground pipe network; the early warning line includes several communication nodes connected in series from the first node to the last node, and the first node is connected to the control center for sending out alarm signals; the adjacent communication There are connection cables between the nodes, and the connection cables are connected to the corresponding communication nodes through electrical connectors. The connection cables are used for communication between each communication node and the control center, and for unidirectional power supply from the first node to the tail node; the electrical connector is used for The connection between the connecting cable at its location and the corresponding communic...

Embodiment 2

[0058] like figure 2 As shown, the only difference from Embodiment 1 of the early warning system is that the early warning line connected to the control center in this embodiment only extends in one direction. Certainly, there may be at least two warning lines in this direction.

[0059] Example of early warning device

[0060] The early warning device includes the communication node in the above embodiment, as well as a connecting cable and an electrical connector.

[0061] Each node needs power supply and communication between the node and the control center, so the connecting cable must have communication and power supply functions. An embodiment such as Figure 5 , respectively set the communication line (such as RS485, CAN bus, etc.) and the power line. Another implementation is as Image 6 As shown, only the power line is set, and the communication is realized by means of power line carrier. That is, only one pair of cables is designed in the node and the connecti...

Abstract

The invention relates to an underground pipe network early warning system and an early warning device. The underground pipe network early warning system comprises a control center. The control center is connected with at least one early warning line. The early warning lines are laid in an earth layer higher than an underground pipe network in depth. The early warning lines comprise a plurality of communication nodes which are successively and serially connected from a first node to an end node, and the first node is connected with the control center used for emitting an alarm signal. A connection cable is arranged between two adjacent communication nodes, the connection cable are connected with corresponding communication nodes through electric connectors, and the connection cable is at least used for the communication between each communication node and the control center. Each electric connector is used for cutting off the connection between the connection cable and the corresponding communication node arranged at the position of the electric connector under an external force. The underground pipe network early warning system and the early warning device can well protect the underground pipe network; in addition, communication and power supplying are realized in a wired mode, and effective and accurate positioning is performed.

Description

technical field [0001] The invention relates to an underground pipe network early warning system and an early warning device. Background technique [0002] In this paper, the underground pipeline network refers to the lines or pipelines laid at several depths underground such as power cables, signal cables, communication optical cables, water pipelines, and gas pipelines. [0003] During the use of the underground pipe network after the laying is completed, it will encounter damage caused by human external forces such as construction, man-made damage, or other emergencies, such as earthquakes, explosions, ground subsidence and other non-human external forces. The normal work of the network can lead to serious safety accidents. Therefore, it is necessary to design an effective, simple and low-cost early warning device to prevent the underground pipe network from being damaged by external forces. [0004] The early warning device needs to realize the following functions: ...
