Tower crane working condition detection method based on Bluetooth technology and detection system

Abstract

The invention discloses a tower crane working condition detection method based on a Bluetooth technology. The tower crane working condition detection method comprises the steps that starting is carried out, communication connection is carried out, then tower crane state detection is carried out, early warning judgment or alarm judgment is carried out by confirmation modules, then alarm processing or early warning processing is carried out, and finally signal conversion and output are carried out. A detection system constructed according to the tower crane working condition detection method comprises a display screen, an alarm lamp, a buzzer, a rotation sensor, a stroke sensor, a height sensor, a second Bluetooth connection module, a second decryption module and a proximity induction switch, all of which are connected with a central control unit. The rotation sensor, the stroke sensor and the height sensor are each connected with the corresponding confirmation module, a constant current driver, an LED light source, a photoresistor, an electromagnetic switch, three conversion output modules, a first Bluetooth connection module and a first decryption module. By means of the method and the system, the production cost can be reduced, and the method and the system have the advantages of being high in working efficiency, high in use safety, convenient to operate, high in use flexibility and long in service life.

Description

technical field [0001] The invention relates to a tower crane detection technology, in particular to a tower crane working condition detection method and detection system based on bluetooth technology. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites. It mainly uses the rotating boom and luffing trolley to accurately transfer components or materials to any part covered by the boom; because the overall volume of the tower crane is large, In order to ensure the normal and safe operation of the tower crane, a safety monitoring system is generally installed on the tower crane to detect the status of each working condition of the tower crane; because the entire safety monitoring system needs to store the working conditions of each position of the tower crane, Detection, judgment, and different feedback signals based on the judgment results, and the positions that need to be detected on the tower crane include the height o...

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It mainly uses the rotating boom and luffing trolley to accurately transfer components or materials to any part covered by the boom; because the overall volume of the tower crane is large, In order to ensure the normal and safe operation of the tower crane, a safety monitoring system is generally installed on the tower crane to detect the status of each working condition of the tower crane; because the entire safety monitoring system needs to store the working conditions of each position of the tower crane, Detection, judgment, and different feedback signals based on the judgment results, and the positions that need to be detected on the tower crane include the height of the tower crane hook, the rotation angle of the tower crane, the amplitude of the trolley, etc., which requires the entire safety monitoring system and When carrying out specific work, more functional control units are required for support, and the overall production cost is relatively high; and because there is a certain distance between the general tower crane and the main control cabinet, it will be necessary to Only by cooperating with operators, ground commanders and central monitoring personnel can accidents be avoided, and such a transmission method needs to spend a lot of time on information transmission, resulting in low overall work efficiency

Therefore, the existing tower crane working condition detection system has the problems of high production cost and low work efficiency.
