Description

Technical Field

[0001] The present invention relates to the technical field of shield equipment supervision, and in particular to a shield equipment operation data supervision system and method based on the Internet of Things. Background Art

[0002] Shield equipment is a kind of engineering equipment used in underground tunnels. It is mainly used for underground tunnel excavation and construction machinery and equipment. It is mainly composed of shield machine, propulsion system, tool system, support system, control system, etc. Shield machine is the core part of shield equipment. It is usually composed of front tool system, propulsion system and rear support system. The shield machine excavates the stratum through the tool system, and then pushes the excavated rock and soil layer to the rear through the propulsion system. At the same time, the support system is responsible for supporting the surrounding strata to ensure the safety of construction. At present, the Internet of Things technology is often used in the operation data supervision of shield equipment. The application of Internet of Things technology can realize real-time supervision and remote control of the operation data of shield equipment. The operation status and environmental information of each part of the shield machine can be obtained through sensors, so that the operation status and environmental information of the shield equipment can be grasped in real time, and the abnormal state can be responded to in time to reduce the possibility of accidents. In addition, the Internet of Things technology can also realize the safety monitoring and early warning management of shield equipment. Through the networking of equipment, the safety risks in the operation process of the equipment can be monitored, and alarms can be issued in time and corresponding emergency measures can be taken to ensure the safety of the construction site and the health of personnel.

[0003] A large amount of operation data is generated during the operation of the shield equipment. These data include sensor data, working parameters, operation records, etc. The information covered by these data is very extensive, and during the operation of the shield equipment, the operation data of the shield equipment are not independent of each other, but are interconnected and influence each other. The operation data of different shield equipment jointly affect the equipment operation status of the shield equipment during the construction process. However, the current monitoring and early warning of the equipment operation status of the shield equipment rarely involve the analysis of the mutual influence between the operation data, which will lead to inaccurate judgment of the operation status of the shield equipment, and may even cause safety accidents during the construction of the shield equipment, causing huge losses to the construction. Summary of the invention

[0004] The purpose of the present invention is to provide a shield equipment operation data monitoring system and method based on the Internet of Things to solve the problems existing in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a shield equipment operation data supervision method based on the Internet of Things, the method comprising:

[0010] Furthermore, step S100 includes:

[0012] Step S102: Obtain each historical equipment operation record of the shield equipment stored in the equipment supervision cloud platform, and obtain the marked equipment advancement data of the shield equipment from the historical equipment operation records, where the marked equipment advancement data is the average value of the equipment displacement and equipment speed of the shield equipment in the historical equipment operation records;

[0014] Step S104: Calculate the marked equipment operation value E of the ath historical equipment operation record of the shield equipment a :

[0015]

[0016] Among them, L a is the equipment displacement of the shield equipment in the ath historical equipment operation record; is the average speed of the shield equipment in the ath historical equipment operation record;

[0017] Step S105: Obtain each historical project construction record of the shield equipment, and extract the historical construction period of the shield equipment from each historical project construction record, and collect several historical equipment operation records belonging to the same historical construction period to obtain a historical equipment operation record set corresponding to each historical project construction record;

[0018] Step S106: Obtain the time point of project construction start in each historical project construction record, and sort each historical project construction record of the shield equipment based on the chronological order of the time points, and sort the historical equipment operation records in the historical equipment operation record set corresponding to the historical project construction record according to the chronological order based on the marked time points corresponding to the historical project construction records;

[0019] Step S107: Calculate the marked device operation threshold of the historical device operation record set corresponding to each historical project construction record, where the marked device operation threshold F of the historical device operation record set corresponding to the b-th historical project construction record is b :

[0020]

[0021] Where j is the total number of historical equipment operation records in the historical equipment operation record set in the b-th historical project construction record; is the marked equipment operation value of the i-th historical equipment operation record in the historical equipment operation record set in the b-th historical project construction record;

[0022] Step S108: randomly selecting the cth historical equipment operation record from the historical equipment operation record set corresponding to the bth historical project construction record, and classifying the cth historical equipment operation record, wherein the specific classification process is: when the marked equipment operation value of the cth historical equipment operation record in the historical equipment operation record set corresponding to the bth historical project construction record is less than the marked equipment operation threshold of the historical equipment operation record set corresponding to the bth historical project construction record, the cth historical equipment operation record is recorded as a marked historical equipment operation record;

[0023] Step S109: Based on the marked equipment operation threshold of the historical equipment operation record set in each historical project construction record, the historical equipment operation records in the historical equipment operation record set corresponding to each historical project construction record are classified to obtain the marked historical equipment operation records of the shield equipment.

[0024] Further, step S200 includes:

[0025] Step S201: Acquire each marked historical equipment operation record of the shield equipment, and extract the marked historical equipment operation data from the marked historical equipment operation record, wherein the marked historical equipment operation data includes data corresponding to each equipment operation parameter of the shield equipment;

[0026] Step S202: Acquire characteristic equipment operation data of the shield equipment stored in the equipment supervision cloud platform, where the characteristic equipment operation data includes preset characteristic parameter rating values ​​of various equipment operation parameters of the shield equipment;

[0033] In the above steps, the characteristic parameter influence values ​​of various equipment operating parameters of the shield equipment are calculated to analyze the influence degree of various equipment operating parameters on the equipment operating status of the shield equipment. This is because the larger the characteristic parameter influence value of a certain equipment operating parameter, the more the average value of a certain equipment operating parameter in the historical equipment operation record when the shield equipment advancement displacement is less than the normal advancement displacement is far less than the preset characteristic parameter rated value. This means that the data change of a certain equipment operating parameter has a much greater impact on the equipment operating status of the shield equipment than the preset degree. At the same time, it also means that a certain equipment operating parameter is very likely to be affected by other equipment operating parameters during the operation of the shield equipment. Therefore, the acquisition of the characteristic equipment operating parameters of the shield equipment is not only conducive to analyzing the equipment operating status of the shield equipment, but also makes the analysis of the equipment operating status of the shield equipment more accurate and scientific.
