Preferably, the frequency converter module transfer feedback speed signal.
Compared with prior art, usefulness of the present utility model is：Employ terminal and subtract stroke technology, can be to elevator
More accurately slowed down control, in elevator operation exception, it is to avoid sink to the bottom or rush to summit event, improved the safety system of elevator
Number.By the technology, space length do not reach require when, if ensureing that rate limitation exists during cage operation incoming terminal
One relatively low value, then can shorten the depth of pit and the height of top layer.
Brief description of the drawings：
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the utility model data transfer flow block diagram.

Specific embodiment：
Below in conjunction with the accompanying drawings and specific embodiment is described in detail to the utility model：
Terminal as shown in Figure 1 subtracts travel control system, including PAD master boards 1, and the PAD master boards 1 include limit
Fast device side coder module 2, traction machine main shaft side coder module 3 and floor signal transport module 4, the PAD master boards 1
It is connected with the communication of PJS terminal slowdowns module 5, the PAD master boards 1 are connected with the CDA auxiliary communications of control panel 6, and the CDA is auxiliary
Helping control panel 6 includes floor signal transport module 4, SEB detection signals module 7, the second band-type brake SEB modules 8, traction machine main shaft side
Coder module 3 and frequency converter module 9, the frequency converter module 9 are connected with the communication of main shaft side coder module 10, the CDA
Auxiliary control panel 6 is connected with the communication of PJS terminal slowdowns module 5.
Limiter of speed side coder module 2 is different with the signal of main shaft side coder module 10.Control panel is aided in CDA
In system, encoder of the monitor board input mounted in motor-side（It is different with master board system）Signal, therefore also can correctly monitor
Elevator speed.
The terminal subtracts travel control system and obtains terminal slowdown switching signal by way of coding.In upper and lower terminal one
Determine some positions in region, a number of terminal location switching point detection is set.Upper and lower terminal is set altogether such as in hoistway
14 position signalling test points, i.e. speed per hour of the car at the terminal difference position of the switch is detected by the encoder of two-way independence
Degree.Code device signal takes from the encoder of traction machine main shaft side all the way, and the encoder of limiter of speed side is taken from another road.Two-way is encoded
Device signal and floor signal enter two completely self-contained speed monitoring plates simultaneously, and two-way code device signal is known respectively
Not, and between two speed monitoring plates position signalling and velocity amplitude are mutually compared further through communication, if it find that two
The fiducial value deviation of person is excessive, then close the power supply of main frame immediately, and is stopped by brake, two pieces of speed monitorings
Plate is all controlled to brake.Four high speed bistable switches are installed in car outside, in the hoistway on lower terminal position respectively fill
There is the signal magnet steel of seven groups of 1 to 4 varying numbers and arrangement, it is defeated with the coding for constituting each 7 position switch signals of upper and lower terminal
Enter.During elevator runs up, when switching detection by upper terminal position, if obtained by encoder pulse signal of change
The elevator position data and the terminal location switch data of standard for going out have an obvious gap, and control system will control elevator to force to subtract
Speed, to ensure that elevator can stop in normal travel.
In order to more reliably ensure the terminal slowdown of elevator, one piece of attaching terminal deceleration monitor board is also set up in systems
（CDA aids in control panel）.Attaching terminal deceleration monitor board is to make elevator jerk by control terminal deceleration protective relay.
When it detects that elevator may terminal slowdown it is out of control or hypervelocity when, will control terminal deceleration protective relay release.Due to this
The contact of relay directly controls all input signals of main contactor, band-type brake contactor and frequency converter, so the relay
Release also with regard to control elevator jerk.Stop the terraced relief relay in elevator to continue to discharge, can also just control the elevator can not
Start.Terminal slowdown protective relay is also controlled by mainboard simultaneously, only when both sides allow relay adhesive its ability adhesive.
Limiter of speed side coder module 2, traction machine main shaft side coder module 3 and limiter of speed side coder module 10
Independently transmission speed signal.
The transmission speed feedback signal of the frequency converter module 9.Frequency converter collects rate signal, is transmitted CDA auxiliary
Control panel is helped, speed measure feedback effect is played.
It is emphasized that：The above is only preferred embodiment of the present utility model, not the utility model is appointed
What formal limitation, every any simple modification made to above example according to technical spirit of the present utility model, etc.
With change and modification, still fall within the range of technical solutions of the utility model.
