In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of elevators to call out communication system outside,
The human-computer interaction of boarding personnel and electric life controller are realized by two-wire bus.
In order to realize above-mentioned target, the utility model adopts the following technical scheme：Communication system is called out outside a kind of elevator,
It is characterized in that, including：It electric life controller, two-wire bus and is connected to several elevators in bus Wai and calls out communication board；Each elevator
Outer communication board of calling out realizes communication connection by two-wire bus and electric life controller, and communication board is called out outside electric life controller parsing elevator
On signal, and elevator is controlled according to analytic signal.
Further, the electric life controller includes：First singlechip is the core of electric life controller；Two-wire system is modulated
Demodulator circuit is connected by reduction voltage circuit and communication data line with first singlechip, and communication board biography is called out outside elevator for receiving
The signal of demodulation is delivered to first singlechip by defeated instruction.
Further, calling out communication board outside the elevator includes：Second singlechip, display controller and memory interface, the
Two microcontrollers are connected with memory interface, display controller respectively, and display controller receives externally input instruction and shows electricity
The operating status of ladder；Instruction is transmitted to electric life controller by second singlechip；Second singlechip transfers outside from memory interface
Information, and external information is shown on display controller.
Further, the memory interface is SD card interface.
Further, the system also includes the voltage sources that electric current is provided for bus.
The utility model is beneficial in that：The utility model proposes communication system is called out outside a kind of elevator, with two wires
Bus processed replaces existing four-wire system bus to carry out the human-computer interaction of boarding personnel and electric life controller, simplifies connection line,
Cost is reduced, and can ensure information communication quality.

Communication board 30 is called out outside terraced, and communication board 30 is called out outside each elevator and realizes that communication connects by two-wire bus 20 and electric life controller 10,
Electric life controller 10 parses the command signal called out outside elevator on communication board 30, and is controlled elevator according to analytic signal.This
Outside, the system also includes the voltage sources 40 that electric current is provided for bus.
With reference to shown in Fig. 2, the electric life controller 10 includes：First singlechip 11 is the core of electric life controller 10；Two
Line modulation-demodulation circuit 12 is connected by reduction voltage circuit 13 and communication data line with first singlechip 11, for receiving electricity
The terraced outer instruction for calling out communication board transmission, first singlechip 11 is delivered to by the signal of demodulation.
Preferably, calling out communication board outside the elevator includes：Second singlechip, display controller and memory interface.Second
Microcontroller is connected with memory interface, display controller respectively.Display controller receives externally input instruction and shows elevator
Operating status.Instruction is transmitted to electric life controller by second singlechip, and second singlechip transfers external letter from memory interface
Breath, and external information is shown on display controller.The memory interface is SD card interface or USB interface, by depositing
Memory interface can easily import external data, and be shown on display controller, such as distributing video advertisement on it
Etc. contents.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that the invention is not limited in any way for above-described embodiment, it is all to be obtained by the way of equivalent substitution or equivalent transformation
The technical solution obtained, all falls in the scope of protection of the utility model.
