Abstract
The elevator network control system includes a main control unit PLC, an RS442/CAN converting board, an outer calling control board and a operating panel control board, where the converting board collects and processes the calling signal for PLC, transmits PLC selected calling signal and storey display signal between control boards, and the bus between control boards are CAN bus. The present invention has the advantages of saving in hardware resource owing to no use of traditional one-to-one connection mode, low installation and maintenance cost, digital signal transmission, self-diagnosis capacity, powerful anti-jamming capacity and high system reliability.
Description
The present invention relates to a kind of elevator network control system.Can realize monitoring, early warning to elevator by this control system, functions such as warning can realize the operation of elevator list ladder, the in parallel and how terraced team controls of two ladders etc.
Line-connection type is adopted in existing elevator control, promptly adopts direct connections such as cable, connection terminal, often needs many hardware, and trouble is installed; Because direct-coupled type, when breaking down the back Laboratory Fee, and the elevator reliability of operation is also not ideal, therefore is necessary to provide elevator network control system.
The purpose of this invention is to provide a kind of elevator network control system, this system reliability is good, and self diagnostic capability is arranged, and can save installation, maintenance cost.
For achieving the above object, the present invention takes following design plan: this elevator network control system comprises: main control unit PLC, RS442/CAN change-over panel (one), outgoing call control desk (three), control wheel control desk (two), wherein change-over panel () is for PLC collects, the building signal is exhaled in arrangement, be responsible for control desk (two) simultaneously and transmit calling signal and the layer display signals of having been chosen by PLC with control desk (three), the kind line type between control desk (), (two), (three) is the CAN bus.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of network control system of the present invention
Fig. 2 is a RS422/CAN change-over panel FB(flow block) of the present invention
Fig. 3 is RS442/CAN change-over panel electrical schematic diagram (control desk one)
Fig. 4 is control wheel control desk electrical schematic diagram (control desk two)
Fig. 5 is an outgoing call control desk electrical schematic diagram (control desk three)
Among Fig. 1,1 is main frame PLC, 2 RS422/CAN change-over panel control desks () for CPU in the middle of containing, and 3 is that outgoing call control desk (three) 4 is control wheel control desk (two), signal between main frame PLC and the RS422/CAN change-over panel [claiming control desk () again] is in the unit time, bi-directional.Control desk (one) is compiled calling signal and is responsible for control desk (two) and transmits calling signal and the layer display signals of having been chosen by PLC with control desk (three); Kind line type between control desk (), (two), (three) is the CAN bus, distinguishes the communication rank with the descriptor in the CAN frame structure, distinguishes floor position to transmit content; Exhale ladder control and layer that control desk (two), (three) are responsible for this position show indication.
Wherein, PLC CPU100MS is to passing signal one time, and outgoing call, interior choosing → CPU have only CPU to accept, and judge by control byte.
The software of elevator bus is the software association line by the inside definition, by mutual contact, both sides observe mutually, approval mutually, transmit data mutually according to this agreement jointly and finish, this agreement comprises: 1, PLC to the frame 2 of middle CPU, the frame from middle CPU to PLC 3, middle CPU to outgoing call and cab 4, outgoing call to middle CPU5, cab to middle CPU.Wherein: (one), PLC are to this frame of frame of middle CPU totally 19 bytes (be used for PLC to the 100ms of middle CPU to passing)
(2), totally 18 bytes of this frame of frame from middle CPU to PLC, the meaning of all is the same, only lacks one and shows byte.(3), middle CPU is to outgoing call and cab
(4) outgoing call is to middle CPU
(5) all are the same just to middle CPU for cab: data bit be only to be number of floor levels AMR=0EFH
And control judges that the position is 00000000b ACR=0 ... H
Number of floor levels
By transportation protocol, data transmit the transmission that both sides realize data.For example: elevator outgoing call (under 8 layers) data definition form is as follows:
The concrete data that transmit are: 01001000 promptly: 48H can judge 8 layers in elevator by above-mentioned agreement and exhale under having when middle CPU receives these data after, controls elevator and is 8 layers and goes to connect the people.It is identical therewith that other unit transmits data.PLCCPU
100MS selects passing in the signal CPU → outgoing call
PLC sends out number, and others all receives
Choosing → CPU in the outgoing call
Have only CPU to receive
Judge by control byte
Advantage of the present invention:
Because elevator network control system has broken traditional connected mode one to one, thereby saved a large amount of Hardware resource, such as electric wire, binding post etc. have reduced cost, have reduced corresponding hardware and auxiliary facility Mounting design work; Save standing charges: because of elevator network control of the present invention system have from diagnosis and so The barrier disposal ability, in case node breaks down, malfunctioning node is connected automatic disconnection and bus, and with event Barrier information sends the master control unit to, and the user can be by master control unit inquiry fault information and handling failure early, Stop the ladder time thereby shortened; Because adopting digital communication modes, anti-interference ability is strong, has improved system Reliability.
