Abstract

The invention provides a bus network, a control system and a crane. The bus network comprises a bus, a main controller, a super-lift controller, a first terminal resistor, a second terminal resistor, a control switch and a third terminal resistor, wherein the main controller and the first terminal resistor are fixedly connected with the bus; the super-lift controller and the second terminal resistor are detachably connected with the bus; the control switch and the third terminal resistor are connected with each other in series and then connected with the bus, and are located between the main controller and the super-lift controller; when the super-lift controller is connected with the bus, the control switch automatically switches off; and when the super-lift controller and the second terminal resistor are disconnected with the bus, the control switch automatically switches on. According to the technical scheme provided by the invention, a communication protocol is simplified, the working amount of programming is reduced, and the problem that the communication of a network is cut off after a super-lift is detached can be solved.

Description

technical field [0001] The invention relates to the field of hoisting equipment, more specifically, to a bus network, a control system and a crane. Background technique [0002] At present, the network data transmission between the main controller of construction machinery and the super-lift controller is generally in a bus network. [0003] Such as figure 1 As shown, the bus network includes a bus 4, a main controller, a left super-start controller 10, a right super-start controller 20, a first terminal resistor 1, and a second terminal resistor 2, and the main controller includes a first controller 21, a second terminal resistor 2 Two controllers 22, the third controller 23, the fourth controller 24 and the display 25, because the left super-lifting controller 10, the right super-raising controller 20 and the second terminal resistor 2 can be disassembled together with the super-lifting arm Yes, so when the super-lifting arm is disassembled, one of the two ends of the bu...
