Abstract
The utility model relates to an information wrong-floor prevention photoelectronic device with magnetic shielding plates, which comprises a transmitting element, a receiving element and the magnetic shielding plates, wherein the transmitting element and the receiving element are positioned on the same side; the magnetic shielding plate is positioned in front of the transmitting element and the receiving element; floor position information is arranged on the magnetic shielding plate of each floor; the receiving element receives the floor position information through the reflection of the magnetic shielding plates; and the floor position information on the magnetic shielding plate is a bar code, a numeric symbol or an identification symbol. In the technical scheme, the floor information is arranged on the magnetic shielding plates, and the receiving element receives and identifies the floor information through the way of reflection, so that a master control system of an elevator can directly determine the floor positions, and the wrong floor problem before initialization of the master control system of the elevator in case of emergency is avoided. The photoelectronic device improves the safety of the elevator effectively, and has the advantages of simple structure, high reliability and practicability.
Description
Technical field
The utility model relates to a kind of hoistway elevator protective device, especially relates to the anti-disorderly layer of a kind of information formula and hides the magnetic sheet electrooptical device.
Background technology
In the prior art, as shown in Figure 2, radiated element 1 and receiving element 2 are installed on the car of elevator and move with car, radiated element 1 sends radiation wave 3, convert electric signal to behind the receiving element 2 received radiation ripples 3, amplify the master control unit that passes to elevator, the expression lift car does not arrive stop.When process indicates the screening magnetic sheet 5 of stop information, radiation wave 3 is blocked, receiving element 2 does not have this information of radiation wave 3 irradiations to pass to the master control unit of elevator equally, express the elevator car arrives stop, from the above, this system is only expressing two information, and 1, lift car do not arrive dockable stop, 2, the stop that will stop of elevator car arrives; Arrive the N stop and work as elevator, this information has only when carrying out " hoistway self study " this initialized work by elevator and just can know, the elevator master control unit is from the bottom, every just adding up through a screening magnetic sheet write down a stop, floor is high more, write down many more, and when work CPU to calculate elevator all the time and be in which stop.
Yet in the actual moving process of elevator, because some is former thereby cause the elevator accident to stop or after fault resets, what is called " disorderly layer " phenomenon appears in elevator master control unit sometimes, be that CPU is in order to handle high level interrupt event, and lost be positioned at what the layer data message, after the elevator master control unit is resumed work, then need slowly mobile car to carry out initialization to bottom position, it is the data message that starting point begins to count again to determine floor, this phenomenon is big more for the probability that the high more elevator of floor occurs, when taking situation such as cpu resource for how terraced team control or other and taking place, also can cause floor primary data information dropout, and increase the possibility of the generation of " disorderly layer ", the probability that incident although it is so takes place is very little, but influence that produces and insecurity are often relatively more serious, and for example " rushing to summit " or " at the bottom of the crouching " phenomenon appears in lift car.
The utility model content
In view of this, the technical problems to be solved in the utility model is to provide the anti-disorderly layer of a kind of information formula to hide the magnetic sheet electrooptical device, in the technical program, hide the floor information that is provided with on the magnetic sheet, receive identification by receiving element, allow the elevator master control unit can directly determine the place floor position by reflection way, avoided the elevator master control unit, when emergency case occurring, the problem of random layer before initialization, thus remedied above-mentioned the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that the anti-disorderly layer of a kind of information formula hides the magnetic sheet electrooptical device, comprise radiated element, receiving element and screening magnetic sheet, described radiated element and receiving element are positioned at homonymy, the screening magnetic sheet is positioned at the place ahead of radiated element and receiving element, the screening magnetic sheet that is positioned at each floor is provided with the location information of place floor, and receiving element obtains the location information of place floor by the reception of the information backward wave of screening magnetic sheet.
The floor position information that is provided with on the described screening magnetic sheet is bar code, symbol of numeral or distinguishing mark.
The technique effect that the utility model reaches is as follows: the anti-disorderly layer of a kind of information formula hides the magnetic sheet electrooptical device, in the technical program, hide the floor information that is provided with on the magnetic sheet, mode by the reflective information backward wave receives identification by receiving element, allow the elevator master control unit can directly determine the place floor position, avoided the elevator master control unit, when emergency case occurring, the problem of random layer before initialization, the technical program effectively raises the safety of elevator, simple in structure, practical, good reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a prior art structural representation in the utility model.
Among the figure, 1 radiated element, 2 receiving elements, 3 radiation waves, 4 bar codes, 5 hide magnetic sheet, 6 information backward waves.
The specific embodiment
As shown in Figure 1, the anti-disorderly layer of the information formula that the utility model relates to hides the magnetic sheet electrooptical device, comprise radiated element 1, receiving element 2 and hide magnetic sheet 5, described radiated element 1 and receiving element 2 are positioned at homonymy, screening magnetic sheet 5 is positioned at the place ahead of radiated element 1 and receiving element 2, the screening magnetic sheet 5 that is positioned at each floor is provided with the bar code 4 of place floor, and receiving element 2 is by hiding bar code 4 information of magnetic sheet 5 reflection reception place floors.Receiving element 2 obtains bar code 4 information of place floor by the reception of the information backward wave 6 of screening magnetic 5 plates.
In the utility model, the floor position information that is provided with on the described screening magnetic sheet 5 also can be that symbol of numeral or other can be by the out of Memory of receiving element 2 identifications.
At work, bar code 4 on the described screening magnetic sheet 5 that is provided with bar code 4 is unique in this hoistway, and unrepeatable bar code 4, when lift car does not move to stop, receiving element 2 can not be received the information backward wave 6 that reflects, when lift car moves to certain stop position, the radiation wave 3 that radiated element 1 sends is radiated at and produces information backward wave 6 on the bar code 4 that hides magnetic sheet 5, information backward wave 6 shines the information that just gives expression to a stop on the receiving element 2, because each layer hides bar code 4 differences on the magnetic sheet 5, the information of stop has uniqueness, the master control unit that such information passes to elevator more accurately and reliably, the situation that can greatly reduce elevator " disorderly layer " takes place.
Hide the bar code 4 on the magnetic sheet 5 in the utility model, can adopt reflex-reflective material to make, also can will make with reflex-reflective material around the bar code 4.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
