Abstract
The utility model provides an elevator control device based on a CAN (controller area network) bus, which comprises a non-contact IC (integrated circuit) card reading unit, a CAN bus communication interface unit, an RS 422 interface unit, a main controller and an I/O (input/output) interface unit. An IC card identification signal output end, a transmitting port and a receiving port of the non-contact IC card reading unit are connected with an external terminal, a receiving port and a transmitting port of the main controller respectively, the CAN bus communication interface unit, a data bus of the main controller is respectively connected with the CAN bus communication interface unit and a data bus of a display and sound driving unit, and the I/O interface unit is connected with the main controller. The elevator control device realizes communication with an operation center by the aid of the CAN bus, has the advantages of long communication distance, high interference-resistant performance and reliability and the like, and simultaneously brings convenience for realizing integration with intelligent systems of other buildings.
Description
Technical field
The utility model relates to elevator control aggregate, relates in particular to a kind of elevator control gear based on the CAN bus.
Background technology
Along with making constant progress of society, the raising day by day of people's material and cultural life, the city high rise building mansion emerges in an endless stream, and elevator is widely used in these high buildings and large mansions.Present elevator uses and management is to rely on manual work to carry out; Thereby exhaust human resources, because there are special demands in some entity and individual to some floor, do not allow other people to get in addition; Therefore existing elevator functions can not satisfy these requirements of people, can't realize control.
Existing, the non-contact IC card lift management system is in order to realize the personnel of elevator to be passed in and out control, guarantees that safety is with convenient.But lift management system all adopts RS485 bus and administrative center's communication at present, and communication distance and antijamming capability have certain limitation relatively.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, convenient management, the elevator control gear based on the CAN bus that communication distance antijamming capability far away is strong.
The purpose of the utility model realizes through following technical scheme.
A kind of elevator control gear based on the CAN bus; Comprise: contactless IC card read/write unit, CAN bus communication interface unit, RS422 interface unit, master controller and I/O interface unit; The IC-card identification signal mouth of contactless IC card read/write unit and transmission, receiving port are connected with the external interrupt of master controller and reception, transmission mouth respectively; The data bus of master controller is connected with the data bus of CAN bus communication interface unit with demonstration and sound driver unit respectively, and the I/O interface unit links to each other with master controller.
Preferably, also comprise demonstration and the sound driver unit that links to each other with the control output end of said master controller.
Preferably, the sheet of said CAN bus communication interface unit selects port, reseting port to be connected with the high address port of master controller.
Preferably, the mouth of said CAN bus communication interface unit also is connected with elevator operating instruction control desk input end.
Preferably, also comprise the expansion I/O interface unit that links to each other with master controller.
The utility model embodiment compared with prior art, beneficial effect is: the utility model is realized carrying out communication with administrative center through the CAN bus, it is far away to have a communication distance; Antijamming capability is strong; The reliability advantages of higher, simultaneously, the system integration of also convenient realization and other building intelligent systems.
Description of drawings
Fig. 1 is the utility model hardware principle block diagram.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also shown in Figure 1; Include power interface, contactless IC card read/write unit, CAN bus communication interface unit, master controller, demonstration and sound driver unit, RS422 interface unit and I/O interface unit; The IC-card identification signal mouth of contactless IC card read/write unit and transmission, receiving port are connected with the external interrupt of master controller and reception, transmission mouth respectively; The data bus of master controller is connected with the data bus of CAN bus communication interface unit with demonstration and sound driver unit respectively; The control output end of master controller is connected with the demonstration control input end of demonstration and sound driver unit; The sheet of CAN bus communication interface unit selects the control end of port, reseting port and RS422 interface unit to be connected with the high address port of master controller respectively; The control end of contactless IC card read/write unit is connected with the auditory tone cues input control end of demonstration and sound driver unit; The mouth of CAN bus communication interface unit is connected with elevator operating instruction control desk input end, and the I/O interface unit links to each other with master controller.
Wherein, the I/O interface unit can also be according to the floor needs, self-defined expansion I/O interface.
The working parameter of elevator main controller, authority informations etc. send controller to through the CAN bus, and the record of swiping the card of controller waits and also sends the management computer to through the CAN bus.
After the master controller parameter is provided with completion, gets into and detect the card reader card image, detect the button inputted recurrent state of I/O mouth.After card using information detects, at first carry out the legitimacy of this card and judge, if illegal card writes down the back and finishes the card treatment scheme.If legal card, then judge the floor of entering that this card has.For the individual layer user, automatically this user is sent into designated floor; For many floors user, then detect the floor load button, come judges to hope the floor that gets into.After accomplishing the floor judgement, automatically the user is sent into designated floor, and recorded information.
CAN bus communication interface unit on the elevator main controller, with elevator main controller, other building intelligent system carries out integrated and interlock.Elevator main controller can be notified other equipment with the floor information that needs to get into, and also can accept the dependent instruction that other equipment need be controlled.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
