Specific embodiment
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
As shown in figure 1, a kind of elevator speed control system, including car body 1, it is arranged on the car body 1
Outer bottom light direction is horizontal generating laser 2, and is arranged on some apart from node 3 on hoistway.It is described apart from node 3
Including the blind hole on hoistway and the optical receiver that is arranged in blind hole, each floor be located at below the floor be provided with for
Uplink triggering apart from node 3, be provided with above the floor for descending triggering apart from node 3, the optical receiver with
Floor button equipment is electrically connected with.
Elevator operation is divided into startup speed-raising stage, constant velocity stage and deceleration stop layers stage by the speed control system.Slow down
The stop layers stage is occurred by the triggering apart from node 3, and the speed-time curve in startup speed-raising stage and deceleration stop layers stage is solid
Fixed.When elevator starts every time, the startup speed-raising stage of fixed speed-time graph is first run, and the stage terminates rear automatic
Into constant velocity stage, during constant velocity stage, once by triggering apart from node 3, then automatically into fixed speed-time graph
The deceleration stop layers stage.When lift car runs to distance objective position certain distance, the emergent light of generating laser 2 shines into
Blind hole so that optical receiver receives optical signal, so as to trigger the generation in deceleration stop layers stage.And each floor apart from node
3 need when the floor is called, i.e. when the elevator interior button or elevator outer button of the floor are pressed just effectively.
Some position correction nodes are additionally provided with each floor, the position correction node includes blind on hoistway
Hole one and the optical receiver one being arranged in blind hole one, the optical receiver one are electrically connected with controller.By position correction
Node is improving flat bed degree of accuracy.After the deceleration stop layers stage triggering of elevator, generating laser 2 shines into each blind hole one by one
One, and make optical receiver one receive optical signal, when each optical receiver one is connected to optical signal, it is possible to monitor lift car
Actual position, this actual position is compared with the theoretical position value to the deceleration stop layers stage, difference is such as produced, is then led to
The rotating speed that controller adjusts traction machine is crossed, such that it is able to make lift car accurate stop layers in continuous error modulation.
In elevator constant velocity's stage, if always using a certain specific speed operation, that part when elevator semi-load
Power will be idle, therefore in the elevator speed control system also add speed-selecting mechanism, in different shapes
Different speed are selected to run under state.
The speed-selecting mechanism includes Weight detector and floor detection means, the Weight detector and described
Floor detection means is electrically connected with controller.The Weight detector includes the weight for being arranged on 1 inner bottom part of the car body
Force transducer, the gravity sensor are electrically connected with controller；1 inner bottom part of the car body is provided with notch, and the gravity is passed
Sensor is arranged on notch surface.Detect that by Weight detector loading capacity will reach building to detect with floor detection means
Layer is used cooperatively jointly, elevator is not gathered way or is only increased less speed every interior in short floor gap, and is passed through controller
To control the rotating speed of elevator traction machine, so as to the elevator speed needed for reaching, it is to avoid elevator is in short floor gap every interior frequent
Speed change so that elevator speed change is more safe and reliable.By notch come placement force sensor, car space was not only saved but also had played
The effect of protection pressure transducer.
The floor detection means includes floor induction apparatuss and floor button equipment, the floor induction apparatuss and the floor
Button devices are electrically connected with controller.Floor induction apparatuss detecting floor that elevator is presently in, by floor button equipment come
The floor that detection elevator will reach.Load difference is calculated by Weight detector and floor detection means and floor is poor
Value, and the suitable speed of service is selected according to load difference and floor difference, and the running speed signal is passed to into converter,
Again by the rotating speed of Frequency Converter Control elevator traction machine.
As shown in Fig. 2 the floor induction apparatuss are dry spring induction apparatuss, the dry spring induction apparatuss include U-type groove body 4, point
The permanent magnet 41 and tongue tube 42 of 4 both sides of U-type groove body are not arranged on, and are arranged on 4 notch of U-type groove body
In magnetic isolation plate 43, the tongue tube 42 is connected with normally-closed contact 44, normally opened contact 45 and transfer contact 46.When U-type groove body 4
Notch in when being not inserted into magnetic isolation plate 43, normally-closed contact 44 and transfer contact 46 are generally closed form under the influence of a magnetic field
State.When magnetic isolation plate 43 is inserted in the notch of U-type groove body 4, normally opened contact 45 is closure state.Magnetic isolation plate 44 is fixed on car
Top, dry spring induction apparatuss are arranged on the guide rail of the certain floor position needed for hoistway, by magnetic isolation plate 44 realizing elevator position
The acquisition of confidence breath.
Passenger is either in car, or waits in floor, is required for substantially knowing the corresponding positions of elevator currently operation
Put.Generally, the position signalling for dry spring induction apparatuss being arranged in hoistway to obtain lift car.Dry spring induction apparatuss are separately mounted to
In hoistway in corresponding each floor, magnetic isolation plate 43 on the top of the car connects tongue tube when inserting the dry spring induction apparatuss of certain floor
42 normally opened contact 45, and the signal that elevator reaches the floor is conveyed to controller in time, when magnetic isolation plate 43 inserts other one
After the dry spring induction apparatuss of individual floor, this signal just stops.
The elevator speed control system also includes speed display device, and the speed display device includes being arranged on
The LED display being electrically connected with controller inside car body 1.Passenger in car can learn electricity by LED display
The real time execution speed of ladder, improves the hommization degree of elevator.
Embodiment described above is only that preferred implementation of the present utility model is described, not new to this practicality
The spirit and scope of type are defined.On the premise of without departing from this utility model design concept, this area ordinary person is to this
