Problems solved by technology

[0004] At present, most of the existing real-time monitoring systems do not have a backup monitoring system, so when there is a problem in a certain part of the monitoring system, the entire system will be unusable, and eventually lead to missed detection, which poses a great risk

Embodiment 1

[0026] Such as Figure 1-2 As shown, an automatic monitoring system for tunnel construction includes several groups of local information collection units 1, mobile monitoring units 2, and remote control centers 3;

[0027] The several groups of local information collection units 1 are arranged at equal intervals along the transverse extension direction of the tunnel 4. The structures of the groups of local information collection units 1 are all the same, including a main information collection unit 101, a backup information collection unit 102, and a GPS chip 105. The first microprocessor chip 103 and the first wireless transmission module 104;

[0028] The data transmission ends of the main information collection unit 101 and the backup information collection unit 102 are both connected to the data transmission end of the first microprocessor chip 103, and are used to send the adopted monitoring data about the tunnel 4 to the first micro processor. In the embodiment of the presen...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that the threshold set in the second microprocessor chip 201 includes a first threshold and a second threshold, and the first threshold is less than the second threshold; if the monitoring data is less than the first threshold, If the monitoring point is greater than the first threshold, but less than the second threshold, a mild danger signal is sent to the remote monitoring center; if the monitoring data is greater than the second threshold, A severe danger signal is sent to the remote monitoring center.

[0038] The rest are the same as in Example 1.

[0039] In summary:

[0040] The present invention provides an automatic monitoring system for tunnel construction, which is provided with a main information collection unit and a backup information collection unit. Under normal circumstances, the main information collection unit is set to be in a working state and the backup information collection unit is in a dorman...

Abstract

The invention discloses a tunnel construction automatic monitoring system. The tunnel construction automatic monitoring system comprises several local information acquisition units, a mobile monitoring unit and a remote control center; all the local information acquisition units are spaced in the transverse extending direction of a tunnel and comprise main information acquisition units, backup information acquisition units, first microprocessor chips and first wireless transmission modules; the main information acquisition units, the backup information acquisition units and the first wirelesstransmission modules are all connected with the first microprocessor chips; the mobile monitoring unit is in communication with all the local information acquisition units separately, obtains monitoring data information and monitoring point position information which are sent by the first microprocessor chips of the corresponding local information acquisition units, compares the monitoring data information with the monitoring point position information and sends alarm and / or repair information to the remote control center according to the comparison result. Thus when a certain part in the monitoring system goes wrong, the system can still be utilized, therefore, monitoring is prevented from being missed, the monitoring precision is very high, and the life safety of workers is greatly improved.

Description

Technical field [0001] The invention belongs to the field of automatic monitoring systems, and specifically relates to an automatic monitoring system for tunnel construction. Background technique [0002] With the rapid development of my country's economic construction, the demand for tunnels for intercity trains, high-speed railways, expressways and other engineering projects is also increasing. In the process of tunnel construction, due to the inability to obtain the data of dynamic changes in tunnel surrounding rock pressure in time, accidents such as tunnel collapse often occur, which seriously threaten the personal safety of workers and greatly affect the development progress of the project. [0003] In order to ensure the safe construction of the tunnel project and effectively avoid the occurrence of accidents such as tunnel collapse, it is necessary to provide a system that can monitor tunnel construction-related data in real time, detect danger in time and take effective co...
