The specific embodiment
Below in conjunction with Fig. 1 to Fig. 4, the present invention will be further described:
As shown in Figure 1, a kind of hoisting crane Bluetooth remote control device, in limit switch sensor, g sensor, motor temperature sensor or the LOAD CELLS one or more are set on one or more hoisting crane, one or more in limit switch sensor, g sensor, motor temperature sensor and the LOAD CELLS carry out the transmission of data by a bluetooth controller, monitor and carry out direct control to being monitored the unit.Bluetooth controller also comprises a control panel.Bluetooth controller is a high speed multitask microcontroller.
As shown in Figure 2, each sensor among the present invention and the object of sensor acquisition data, being provided with between many hoisting cranes all is to interconnect and data transmission by bluetooth.This means: the data necessary transmission line is integrated, and similar ProFi bus system or these data lines of CAN bus system there is no need to be installed between two hoisting cranes.The data rate of bluetooth is faster, while high speed multitask microcontroller, and this is state-of-the-art.Can replace oldfashioned PLC fully.Also save the connection of communication cable, reduced the trouble that tediously long connection brings.
And this bluetooth controller is a high speed multitask microcontroller, is state-of-the-art controller at present, and can replace oldfashioned PLC fully.
The mode of this hoisting crane Bluetooth remote control device comprises following several:
When bluetooth controller received the signal that any one limit switch that limit switch sensor sends is opened, bluetooth controller can stop corresponding electric motor automatically.All limit switch signals all are to be sent to bluetooth controller by bluetooth.For example: the situation of limit switch can be carried out quick error analysis in control panel.If limit switch is not used, it will be by disabled in system by long-range installation software.
When bluetooth controller receives the overload signal that g sensor sends, and overload signal will be offered the other system of all these interlocks, overload protective device can be automatically stops the hook of hoisting crane.On control panel, the user sees this situation and monitors.
When bluetooth controller received the motor temperature signal of motor temperature sensor transmission, the user checked the temperature of each motor on control panel; When motor temperature is higher than predetermined dangerous values, blue Tooth remote controller will be warned the user.It all is to pass through Bluetooth transmission that all motor temperatures show.This means that the user can be checked through the temperature of each motor on control panel.
As shown in Figure 3, in the time of two hoisting crane interlocks, if the action of the limit switch of hoisting crane A, when the A hoisting crane stopped, the B hoisting crane also can stop accordingly simultaneously.That is to say that when bluetooth controller received the signal that any one limit switch that limit switch sensor sends is opened, bluetooth controller can stop the electric motor of all hoisting cranes automatically.
