Bluetooth connection method and connection system for multi-frequency conversion control of tower crane

Abstract

The invention discloses a Bluetooth connection method and system for multi-frequency conversion control of a tower crane. The Bluetooth connection method comprises the following steps: acquiring initial Bluetooth connection time; acquiring Bluetooth connection time; judging a Bluetooth condition, and displaying the Bluetooth condition through a security module; and re-limiting the time threshold. The connection system comprises a control center, a timing module, a safety module and a Bluetooth sending module; the control center is electrically connected with a Bluetooth connection module, a Bluetooth detection module used for detecting the connection state of the Bluetooth connection module and a storage module, and the storage module is used for storing the connection time of the Bluetooth connection module and the Bluetooth sending module; one side of the Bluetooth connection module is connected in parallel with a standby connection module, and an interlocking device is arranged between the standby connection module and the Bluetooth connection module; and a threshold value for confirming connection time is set in the timing module. The working efficiency can be improved, and the device has the advantages of being convenient to use and overhaul, simple in structure and high in stability.

Description

technical field [0001] The invention relates to a bluetooth connection system, in particular to a bluetooth connection method and a connection system for multi-frequency conversion control of tower cranes. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites. When the tower crane is performing specific operations, the height of the tower crane control room from the ground is relatively high, and low-sensitivity intelligent personnel are required to conduct remote command and cooperate with the operator. Therefore, The existing tower cranes use Bluetooth and other wireless connection methods for information interaction; but because there may be a certain height distance between the tower crane control room and the ground, the Bluetooth connection method is prone to disconnection and other phenomena, which cannot be discovered in time; Moreover, it needs to be connected again after each disconnection, and configuration man...

[0002] Tower crane is the most commonly used lifting equipment on construction sites. When the tower crane is performing specific operations, the height of the tower crane control room from the ground is relatively high, and low-sensitivity intelligent personnel are required to conduct remote command and cooperate with the operator. Therefore, The existing tower cranes use Bluetooth and other wireless connection methods for information interaction; but because there may be a certain height distance between the tower crane control room and the ground, the Bluetooth connection method is prone to disconnection and other phenomena, which cannot be discovered in time; Moreover, it needs to be connected again after each disconnection, and configuration management is required during each connection process, resulting in a decrease in overall work efficiency

Therefore, the existing Bluetooth connection method and connection system for tower cranes have the problem of low work efficiency during use.
