Detailed description of the invention
The utility model provides a kind of novel elevator and subtracts travel range monitoring apparatus, as shown in Figure 1, comprise subtract journey controller, car tests the speed unit, hoistway learning controller, the signal output part of hoistway learning controller connects the hoistway learning control signal input end subtracting journey controller, the test the speed signal output part of unit of car connects and subtracts the car speed signal input part of journey controller, subtracts the speed control signal mouth of journey controller for connecting the speed control signal input end of elevator master control system.
Fig. 2 subtracts the schematic circuit diagram of travel range monitoring apparatus for novel elevator shown in Fig. 1.The described journey controller that subtracts adopts microcontroller U1, and microcontroller U1 adopts model to be STM32F103R8T6.
The described car unit that tests the speed adopts coder U2, coder U2 adopts model to be E6HZ-CWZ6C, coder U2 is for being arranged on elevator governor axle, rotated by velocity limiter, the A of coder U2, B, Z pin exports corresponding A phase pulse signal respectively, B phase pulse signal, zero signal, the A phase pulse signal output connecting pin of coder U2, B phase pulse signal output connecting pin, zero signal output connecting pin connects the J2-3 pin of microcontroller U1 respectively, J2-4 pin, J2-5 pin, the power end of coder U2, ground terminal connects the J2-1 pin of microcontroller U1 respectively, J2-2 pin.Microcontroller U1, by the pulse count sent in calculation code device U2 certain hour, calculates the speed of current car.
Described hoistway learning controller is for often to open button switch K1, and employing model is F16, and the described button switch K1 that often opens is connected to the public pin J1com of described microcontroller U1 and hoistway learning control signal inputs between pin J1-4.
The speed control signal mouth J5-1 pin of microcontroller U1, J5-2 pin are connected respectively the two power supply input pins of drg YB.
Test phase before elevator operation, need use often to open button switch K1 and carry out elevator hoistways study, learning process is: elevator is dropped to hoistway lower limit (the shaft bottom end position that namely elevator normally runs or inspection and repair shop should reach), press and often open button switch K1, elevator is moved to hoistway upper limit (the well headroom end position that namely elevator normally runs or inspection and repair shop should reach) from hoistway lower limit, then unclamp and often open button switch K1, microcontroller U1 records the overall pulse number that in whole service process, coder U2 exports, be stored in inside its memory device carried as car run-length data.Hoistway lower limit is higher than the end face of shaft bottom energy disperser, and hoistway upper limit is lower than the bottom surface of well headroom energy disperser.
In addition, in order to ensure safety, be set with bottom throw-over point at shaft bottom, be set with top throw-over point at well headroom, when car arrives bottom throw-over point or top throw-over point, elevator master control system will be slowed down to car, in order to avoid bump against energy disperser.Throw-over point position, bottom is higher than described hoistway lower limit, and top throw-over point position is lower than described hoistway upper limit.Test phase before elevator operation, use often open button switch K1 carry out elevator hoistways study time, utilize the step-by-step counting to coder U2, pulse count when microcontroller U1 calculates and stores car arrival bottom throw-over point or top throw-over point, so that contrast judgement when car normally runs.
In car normal course of operation, microcontroller U1 counts according to the real-time pulse of coder U2, judge the speed of car, and judge whether car is in bottom throw-over point or the top throw-over point of stroke, when microcontroller U1 judges that obtaining car is in bottom throw-over point or the top throw-over point of stroke, microcontroller U1 judges whether the moving velocity of now car is greater than the energy disperser command speed prestored, if be greater than, microcontroller U1 will disconnect its J5-1 pin, the output of J5-2 pin, namely the power supply to drg YB is disconnected, after drg YB power-off, damper brake locking, car is forced to slow down, the speed of car or counterweight cushion at collision is made to be less than the design speed of energy disperser, the safety of protection passenger and lift facility, if be not more than, illustrate that elevator master control system achieves normal deceleration, now car speed is no more than the design speed of energy disperser, and now microcontroller U1 is failure to actuate.What microcontroller U1 protected is that dangerous situation appears in the design speed preventing the speed of car cushion at collision from exceeding energy disperser.
Key point of the present utility model is, adopt and subtract travel range monitoring apparatus independent of the novel elevator outside elevator master control system, to be tested the speed unit and subtract journey controller and monitor lift car and whether effectively slow down at bottom throw-over point or top throw-over point by car wherein, if when effectively not slowing down, the power supply of breakaway braking device is controlled by subtracting journey controller, make damper brake locking, car is forced to slow down, thus the command speed realizing energy disperser can lower than the command speed of elevator, the bottom of effective minimizing elevator hoistways and headroom height, greatly save the type selecting cost of energy disperser and the building cost in building.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
