BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 This is a structural principle diagram of the data monitoring host of the utility model. Implementation

[0013] The deep pipeline monitoring and early warning device of the utility model is to drill three or more parallel vertical shafts at the intersection of the existing deep pipeline 5 and the directional crossing, more than 10 meters on the facing side, the depth of the vertical shaft 3 is greater than the depth of the existing deep pipeline 5, and the horizontal distance between each vertical shaft 3 and the existing deep pipeline 5 is equal, and the distance between each vertical shaft 3 is equal. At the same time, the distance between each vertical shaft 3 is less than the diameter of the new pipeline.

[0014] A sensor installation sleeve 4 is provided in the shaft 3, and the installation sleeve 4 is a plastic tube. A wire break sensor 1 is provided inside the installation sleeve 4, and a protective cover 6 is provided on the installation sleeve 4. The protective cover 6 has a threading hole. A data monitoring host 2 is provided on the ground, and the signal line of the terminal of the wire break sensor 1 passes through the threading hole and is connected to the data monitoring host 2.

[0015] The data monitoring host 2 is provided with a power switch, a display screen, a signal port, a DC power supply port, a communication port, a computer data port, and an alarm port; the data monitoring host 2 is provided with a circuit board, which is composed of a processing unit, a function setting and display unit, a multi-channel optical coupling isolation input unit and a signal interface unit, a power module and an input power adjustment unit, a communication interface unit, a computer interface unit, and an alarm interface unit. The disconnection sensor 1 is connected to the signal port through an optical coupling isolation input unit, and an optical coupling is used to isolate the detection circuit and the single-chip microcomputer port, thereby preventing the long-distance probe wire from interfering with the power frequency AC of the circuit; the DC power supply port is connected to an external power supply; a 4G communication module is provided in the communication port, and the computer data port is connected to an external computer; the alarm port is connected to an external sound and light alarm.

[0016] When the device is working, it is necessary to connect the DC power supply interface to the external power supply, the external sound and light alarm to the alarm interface, and the external computer to the computer data interface. Then, the signal line of the disconnection sensor 1 is connected to the signal interface to form a loop between the disconnection sensor 1 and the multi-channel optical coupling isolation input unit and the signal interface unit, and transmit the signal to the input port of the processing unit. At this time, the input port of the processing unit is at a low level. When the external construction personnel start to drill the directional penetration hole, if the signal line of the disconnection sensor 1 is broken, the loop disconnection current becomes smaller, and the input port of the processing unit is at a high level. The processing unit determines which loop is disconnected by cyclically scanning the current and level of each input port. At the same time, the sound and light alarm will sound an alarm and transmit the alarm information to the cloud platform through the 4G communication module.
