[0028] The utility model is further explained below combining with the attached drawing and specific embodiment, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model.

[0029] Referring to Figure 1 The utility model relates to a kind of control systems for multiple cranes, comprising:

[0030] One main control remote controller 1, respectively with first crane 2 and several second cranes 4 carry out wireless communication, for controlling first crane 2 and several second cranes 4 work;

[0031] Several slave remote controllers 3, respectively with several second cranes 4 carry out wireless communication, for respectively controlling several second cranes 4 work;

[0032] First crane 2 respectively with several second cranes 4 between carry out two-way wireless communication, to send fault signal to the crane that does not break down when crane breaks down, the crane that breaks down stops working, the crane that does not break down stops working after receiving the fault signal.

[0033] It should be noted that the master remote controller 1 of the embodiment can control the first crane 2 and the plurality of second cranes 4 to work cooperatively. Taking one first crane 2 and one second crane 4 as an example, when the two cranes do not need to work cooperatively, the master remote controller 1 controls the first crane 2 to operate, and the slave remote controller 3 controls the second crane 4 to operate. When the two cranes need to work cooperatively (for example, the first crane 2 and the second crane 4 need to simultaneously lift materials), the slave remote controller 3 first releases the control of the second crane 4, and then the master remote controller 1 selects to control the second crane 4, at the same time, the master remote controller 1 itself controls the first crane 2, so that after the slave remote controller 3 releases the control, the master remote controller 1 can control the first crane 2 and the second crane 4 simultaneously.

[0034] Further, the master remote controller 1 and the plurality of slave remote controllers 3 are all FST 726M4 PNSPECTRUM3 models. In other embodiments, other models can also be used.

[0035] Further, the master remote controller 1 and the slave remote controller 3 both include a signal transmitter 5, and the master remote controller 1 and the plurality of slave remote controllers 3 all transmit radio frequency signals (specifically, control signals to the crane) through the respective signal transmitters 5.

[0036] Further, the signal transmitter 5 includes but is not limited to FST 726geox.

[0037] Further, the first crane 2 and the plurality of second cranes 4 are all provided with a signal receiver 6; the signal receiver 6 in the first crane 2 performs wireless communication (communication through radio frequency signals) with the signal transmitter 5 of the master remote controller 1; and the signal receiver 6 in the second crane 4 respectively performs wireless communication (communication through radio frequency signals) with the signal transmitter 5 of the master remote controller 1 and the signal transmitter 5 of the slave remote controller 3.

[0038] Further, the signal receiver 6 includes but is not limited to FSE 726rad i obus.

[0039] It is worth mentioning that the master remote controller 1 simultaneously controls the first crane 2 and the plurality of second cranes 4 in the embodiment, which can ensure the synchronization of the plurality of cranes in the linkage lifting of materials, and in addition to the synchronization, the safety of the first crane 2 and the second crane 4 in the cooperative work is also fully considered, which will be described in detail below.

[0040] Further, the first crane 2 and the second cranes 4 are provided with control modules 7 and wireless communication modules 8, the control module 7 and the wireless communication module 8 of each of the first crane 2 and the second cranes 4 are connected, the control module 7 is used to control the wireless communication module 8 to send wireless signals outward; the first crane 2 and the second cranes 4 communicate with each other through the wireless communication module 8, so as to send a fault signal to the crane which does not fail when the crane fails, and ensure that the crane which fails and the crane which does not fail stop working at the same time. The crane of the embodiment can be provided with an LED indicator connected with the control module 7 (programmable logic controller PLC) in the crane, when the crane fails, the programmable logic controller PLC controls the LED light to flicker to inform the staff that the crane fails. In other embodiments, when the crane fails, the control module 7 (programmable logic controller PLC) can also send a fault signal to the master remote controller 1 through an additional communication interface or communication module, and inform the master remote controller 1 that it is not necessary to send a control signal (equivalent to informing the staff that it is not necessary to send a control signal).

[0041] Specifically, taking one first crane 2 and one second crane 4 as an example, when the first crane 2 fails, the control module 7 of the first crane 2 controls itself to stop working, and at the same time, the control module 7 of the first crane 2 also sends a fault signal to the wireless communication module 8 of the second crane 4 through the wireless communication module 8 of the first crane 2, and the control module 7 of the second crane 4 stops working through the wireless communication module 8 of the second crane 4 after receiving the fault signal, whether the second crane 4 can work normally or not. In this way, when one crane fails and stops working, all the other cranes also stop working at the same time, thereby improving the stable use efficiency of all the cranes when working together, and ensuring the safe operation of the cranes.

[0042] Further, the control module 7 in the first crane 2 or the second crane 4 is also connected with the signal receiver 6, and the control module 7 controls the crane to work according to the signal received by the signal receiver 6.

[0043] Further, the control module 7 is a programmable logic controller PLC.

[0044] Further, the wireless communication module 8 is a PN communication module.

[0045] Further, the communication protocol adopted by the wireless communication module 8 between different cranes is Profi net protocol.
