The elevator operation monitor

The utility model relates to a kind of elevator operation control monitor unit, really the auxiliary products technical field of and the middle-size and small-size elevator of saying so.

The monitoring of elevator operation and control are the assurances of elevator safety, normal operation.Yet up to this point, most of middle-size and small-size elevators do not dispose the actv. device for monitoring running state as yet, thereby can not in time find and handling failure.The elevator monitoring device that patent CN2083578U proposes has adopted the time-devision system pulse circuit and has carried out the mode that remote information transmits, and is subjected to the interference of external electromagnetic field easily and causes error code, causes the error of fault judgement and operation.In addition, fault category adopts the code display mode also little directly perceived.

The purpose of this utility model is to provide a kind of appliance computer mechanics of communication to middle-size and small-size elevator, simple and reliable running state long-distance monitorng device.In Control Room, just can observe the running state of elevator at any time.When Lift out of order, this device sends the sound and light alarm signal, and the elevator maintenance personnel just can take the timely trouble-shooting of corresponding emergency schedule according to elevator operation and car present position, save stranded passenger.Remote manual control of using the operation push-button on the monitoring device also can realize the elevator operation.This device is furnished with backup power, to guarantee the usefulness of the emergency relief when the power failure fault.

For realizing what task of the present utility model was finished by the following technical programs.

The utility model by controller 1, monitoring device 2 and communication cable 3 are formed is characterized in that controller 1 is installed in the elevator control cabinet; Link with the elevator control path, monitoring device 2 is installed in the monitoring room; Link with communication cable 3 between controller 1 and the monitoring device 2; Controller 1 is made up of micro controller system basiccircuit, photoelectrical coupler 15, input buffer 14, output latch 16, output driver 17, relay 18, communication interface circuit 7; Monitoring device 2 is made up of micro controller system basiccircuit, segment encode actuator 31, bit code actuator 32,

charactron

33,34, light-

emitting diode

35,36, sound equipment actuator 22, buzzer phone 21, operation push-button 23, communication interface circuit 25.Controller 1 is gathered the running state and the various alarm message of elevator in real time, send monitoring device 2 to through communication cable 3, on corresponding charactron 33, light-

emitting diode

35,36 and buzzer phone 21, M/C button 23 information via communication cables 3 on the monitoring device 2 are sent to controller 1, drive corresponding relays and control elevator.Elevator operation that controller 1 is gathered and alarm message are sent to monitoring device 2 through communication cable 3, show lift car floor of living in by the charactron on the monitoring device 2, light-emitting diode shows elevator operation and alarm message respectively, and buzzer phone is as audible alarm.M/C signal on the monitoring device 2 is sent to controller 1 through communication cable 3, by on the controller 1 with the link operation of contact control elevator of relay 18 of elevator control path.

The good effect that the utility model produced shows, uses micro controller system and computer communication technology, thereby reliability height, antijamming capability are strong.And, the present domestic old-fashioned elevator that falls behind provides the technical support of simple possible for not having monitored control system to renovate.When Lift out of order, this device sends the sound and light alarm signal, and the elevator maintenance personnel just can take the timely trouble-shooting of corresponding emergency schedule according to elevator operation and car present position, save stranded passenger.Remote manual control of using the operation push-button on the monitoring device also can realize the elevator operation.This device is furnished with backup power, to guarantee the usefulness of the emergency relief when the power failure fault.

Further specify technology contents of the present utility model below in conjunction with accompanying drawing.

Fig. 4 is the utility model embodiment block diagram.

See Fig. 1, the utility model that is formed by controller 1, monitor 2 and communication cable 3. Control The running status of device 1 Real-time Collection elevator and various warning message send supervision to through communication cable 3 Device 2 shows and warning at corresponding charactron, light emitting diode and buzzer. On the monitor 2 Manual operation information is sent to controller 1 through communication cable 3, drives corresponding relay and controls The operation of elevator. See Fig. 2, single-chip microcomputer 8, oscillating circuit 5, reset circuit 6, address latch 9, number Form substantially electricity of single-chip microcomputer according to bus 10, program storage 11, address bus 12, address decoder 13 The road. Single-chip microcomputer 8 sends low eight ground through data/address bus 10, address latch 9 to program storage 11 The location code sends the high eight-bit address code through address bus 12 to program storage 11, deposits from program then Reservoir 11 takes out with the corresponding programmed instruction in this address and sends single-chip microcomputer 8 operations back to through data/address bus 10. Shake Swing circuit 5, reset circuit 6 and link with single-chip microcomputer 8, by single-chip microcomputer 8 provide operation during the work of palpus Order and reset signal. Elevator operation and warning message enter the input buffering through photoelectrical coupler 15 Device 14, single-chip microcomputer 8 sends gating signal by address decoder 13 to input buffer 14, passes through then Data/address bus 10 reads the information in the input buffer 14. Single-chip microcomputer 8 process address decoders 13 are to defeated Go out latch 16 and send gating signal, then manual operation information is delivered to the output lock through data/address bus 10 Storage 16 latchs, and passes through the on off operating mode of output driver 17 control relays 18 again. Single-chip microcomputer 8 warps Cross communication interface circuit 7 and carry out communication with monitor 2: send the elevator of gathering to monitor 2 Running status and warning message; Receive the manual operation information that monitor 2 sends. See Fig. 3, by monolithic Machine 24, oscillating circuit 19, reset circuit 20, address latch 26, data/address bus 27, program are deposited Reservoir 28, address bus 29, address decoder 30 forms the (wiring and work former of single-chip microcomputer basic circuits The same Fig. 2 of reason narration). Single-chip microcomputer 24 is translated through the address according to the content and the figure place showing thereof that show information 30 timesharing of code device send gating signal to segment encode driver 31 and bit code driver 32, pass through then data Bus 27 sends segment encode and bit code information to segment encode driver 31 and bit code driver 32, to drive number Pipe 33,34,

light emitting diode

35,36 demonstration. When warning message was arranged, single-chip microcomputer 24 was through sound Ringing driver 22 makes buzzer 21 send alarm sound. Operation push-button 23 links with single-chip microcomputer 24 input ports Connect. The clear key that pushes for emergency then stops the chimes of doom of buzzer 21. Press the manual operation key then to monolithic Machine 24 is sent into the manual operation signal. Single-chip microcomputer 24 leads to through communication interface circuit 25 and controller 1 The news contact; Receive elevator operation and warning message that controller 1 sends; Send hand to controller 1 Moving operation information.

The following drawings exemplifies most preferred embodiment.
