Description
Technical field
The utility model relates to a kind of detecting device that is used for elevator door zone, position and end station (throw-over) signal, particularly a kind of and existing elevator hoistways magnetic isolation plate matches, can realize being independent of the real time monitoring elevator position of apparatus for controlling elevator and the running state detecting device of elevator of speed, it is mainly used in Elevator landing and end station signal detection, the place that elevator sound broadcast, elevator monitoring etc. need elevator position, speed to detect.
Background technology
At present, elevator has become the requisite vertical transportation instrument of skyscraper.About 500,000 ones of the annual newly-increased elevator quantity in the whole world, only Chinese elevator recoverable amount just reaches 1,300,000 ones, and with annual 20% speed increment.In apparatus for controlling elevator, rotary encoder is essential with door zone position and the detection of end station location, and rotary encoder is realized the measurement of exact location, speed, is convenient to the drive controlling of system to elevator, door zone position and end station location detector switch are realized the calibration and the correction of position.People take elevator and not only require accurately to stop the floor that will arrive, and also require ride comfort, safety.Therefore, the elevator that requires that has in running process of elevator adds the sound broadcast function, provides voice suggestion when arriving the purpose floor; And the elevator that requires that has adds monitoring function, so that can the real time monitoring elevator operation.These two kinds of application, for detecting elevator position, speed signal, generally be to obtain by the elevator device its own interfaces, but often elevator producer does not possess for technical know-how, systemic-function, and can not get related data, position and the speed to elevator just detects comparatively difficulty separately like this.Mode in the past adopts that every layer of position installs a magnetic isolation plate additional in hoistway, install two above photoelectric switchs or magnetic inductor switch on the sedan-chair top additional and detect upper and lower door district respectively, and respectively increase by 1 pair of upper and lower side station (throw-over) switch in two ends up and down at elevator, every elevator will have 4 switches to carry out position probing at least like this, increases total number of floor levels in the hoistway and adds 2 corresponding detection accessory such as magnetic isolation plate.This mode cost is higher, difficulty of construction is big.As patent publication No. is that " a kind of detecting device that is used to detect level position of elevator " of CN101597001A is exactly to adopt the two-way Hall switch to detect the mode of level position of elevator.The modem elevator control system realizes the exact location measurement by coder, this detecting device, be that survey precision all can not be compared with coder with antijamming capability, can not realize velocity measurement, every layer also will install the magnet locating plate additional, increase installation difficulty and cost, output signal is an analog quantity, increases to gather difficulty, and for this high interference scene of elevator, be easy to produce error, so few this device that uses in the existing elevator device.Notification number be CN2591006Y's " Elevator landing signalling apparatus " be the same with traditional detection door district signal, this device only is to open a little bar holes on magnetic isolation plate, provided door zone position continuous signal when making its access door district, for in having the elevator device of coder, having little significance, and use this device, also will revise the detection mode of apparatus for controlling elevator flat bed, commonality is very low like this, can't be extensive use of.Said apparatus can only detect flat bed, can not realize velocity measurement, and near every layer of door district, all will install the magnet locating plate additional and on car, adorn cooresponding two Hall switch detection heads, certainly will increase installation difficulty and cost like this, be analog quantity because of output signal simultaneously, gather difficulty so also increase.
Publication number be CN1185406A's the method that is used for monitoring and controlling elevator flat-layer of precision " have improve ", though he also adopts two levels with vertical luminous, the sensitive device of certain displacement to be arranged, the detecting device that the baffle plate in rectangle hole is formed is realized the detection of elevator position.But require to be necessary for special hoistway magnetic isolation plate, and the position of the magnetic isolation plate slot of every layer of elevator all is different, and this is for the detection of existing elevator device, must every layer all installs this magnetic isolation plate additional, consider hoistway space position and cost, this is impossible; For the new clothes elevator, because every layer of magnetic isolation plate is all variant, all strengthened difficulty to installing, producing like this, and single this device has only two paths of signals output, if be applied in the occasion of every layer of equal shape of magnetic isolation plate, can not realize floor school function, need the extra magnetic isolation plate that has square opening that in hoistway, increases to realize, increase cost and installation difficulty like this.Publication number be CN1468195A's " elevator position detector ", this device is provided with the detector of reed switch in the lift car side, the using escalator oral-lateral setting of access trunk by the polylith permanent magnet constitute by detector.Its reed switch with two perpendicular distributions is realized the detection of position.Owing to the reasons such as induction sensitivity of reed switch to magnetic field, this device vertical direction will have certain distance, can not realize miniaturization, and single device can not detect elevator position correcting signals such as end station, base station.Publication number be CN1613738A's " elevator position detector ", it adopts parallel two-way photoelectric switch, and the photoelectric switch that horizontal Tile has disposed two opto-electronic pickups promptly is installed on the lift car side; Be equipped with the check-out console with two row holes on each floor position of access trunk, the length adjustment plate in the hole by check-out console is set carries out the adjustment of floor ground aligned position.This device is a kind of to detecting the improvement whether car is in the position detecting device of door district's scope of each floor and regular stop position, its light path is subjected to external light source easily and disturbs, the detected state instability, the setting of the peristome of the installation of check-out console, length adjustment plate and adjustment be trouble all, and can not realize the detection of elevator service direction, can not realize the detection of position signal.
