Detailed description of the invention
In order to be illustrated more clearly in the utility model, below in conjunction with preferred embodiments and drawings, the utility model is described further.Parts similar in accompanying drawing represent with identical Reference numeral.It will be appreciated by those skilled in the art that specifically described content is illustrative and nonrestrictive below, protection domain of the present utility model should do not limited with this.
As shown in Figure 1, the elevator number measurement mechanism based on digital circuit that the present embodiment provides, comprises
Infrared induction module, comprises two groups of infrared tubes;
Counting module, comprises not gate, two double D triggers and forward-backward counter;
Display module;
Correction module, comprises four infrared distance sensors and micro controller system.
As shown in Figure 2, signal 1 and 2 is respectively the output signal of two groups of infrared tubes, signal 1 derives from one group of infrared tube outside elevator, signal 2 derives from one group of infrared tube inside elevator, when there being people to shut out the light, infrared tube output low level, gets through not gate 3 pairs of output signals and have to arrive signal 4 and 5.6 and 7 are double D trigger, during unmanned turnover elevator, signal 4 and 5 is low level, double D trigger 6, 7 are cleared, when there being people to enter elevator, signal 4 first becomes high level, then remove the clearing to double D trigger 6, along with entering of people, signal 5 becomes high level from low level, for double D trigger 6 provides a rising edge pulse, the output signal 8 of double D trigger 6 becomes high level, when people passes by infrared tube, signal 4, 5 get back to low level more successively, again to binary pair 6, 7 reset, signal 8 is made to get back to low level, thus make the output signal 8 of double D trigger 6 form a rising edge pulse, in like manner, if there is people to walk out elevator, the output signal 9 of double D trigger 7 can form a rising edge pulse, thus will deliver to forward-backward counter respectively into and out of signal,
Forward-backward counter comprises forward-backward counter 10 and forward-backward counter 11, the addend end of forward-backward counter 10 and subtrahend end Received signal strength 8 respectively, 9, when signal 8 provides rising edge pulse, forward-backward counter 10 realizes adding counting, when signal 9 provides rising edge pulse, forward-backward counter 10 realizes subtracting counting, when needs carry or when giving up the throne, forward-backward counter 10 to forward-backward counter 11 send into, to give up the throne signal, forward-backward counter counting machine 10 exports the individual position of display module to, forward-backward counter 11 exports ten of display module to, the counting region that then forward-backward counter is total is 0 ~ 99.
As shown in Figure 3, two groups of infrared tubes 12,13 are arranged on entrance both sides in cage.Four infrared distance sensors 14,15,16,17 are arranged on elevator door inner top.
The mouth of above-mentioned infrared distance sensor 14,15,16,17 is connected with P0.0 ~ P0.3 mouth of micro controller system respectively, setting elevator height is the default height of infrared distance sensor, when there being two people to enter elevator side by side simultaneously, sensor 14,17 first can receive signal simultaneously, namely there is saltus step in P0.0 and the P0.3 mouth of micro controller system simultaneously, through the time delay of one section of setting, micro controller system P1.0 mouth exports a rising edge signal, superpose with signal 8, thus make signal 8 again occur a positive rise, make counting machine again add one; In like manner, if there are two people to walk out elevator simultaneously, first sensor 15,16 can receive signal simultaneously, and now P0.1 and the P0.2 mouth of micro controller system first can occur saltus step simultaneously, P1.1 mouth exports a positive rise and to be added to signal 9 after time delay, makes counting machine again subtract one; These two kinds extra counting process add two people into and out of time counting process, just eliminate the error because two people cause side by side; When having two people while during one-in-and-one-out, sensor 15 and 17 or sensor 14 and 16 can be received information simultaneously, namely when the saltus step simultaneously of P0.0 and P0.2 mouth or the saltus step simultaneously of P0.1 and P0.3 mouth, micro controller system can export a low level immediately and to be added to signal 8 and 9, counting machine is not counted in the case, thus eliminates the error produced because of one-in-and-one-out while of two people.
The installation site of above-mentioned each infrared distance sensor should adapt to the developed width of elevator, be specially and be divided into two rows along lift car depth direction, quantity is the twice that is four that can pass in and out the maximum number of elevator door side by side, and be greater than the width of a people along the spacing in lift car standard width of a room in an old-style house direction and be less than or equal to two people width side by side, make elevator width being less than to three people width side by side, a people can not trigger two infrared distance sensors side by side simultaneously; Two people trigger two infrared distance sensors through out-of-date being bound to side by side simultaneously.
When elevator running gate-width is spent large, the quantity of sensor suitably can be increased.Such as when elevator door can hold simultaneously three people pass in and out time, then two rows should be set, totally six infrared distance sensors, by that analogy.
Except above-mentioned 4 kinds of extraordinary circumstances, micro controller system can not produce interference to signal 8,9.
The utility model improves the deficiency of prior art and scheme, changes existing micro controller system counting into digital circuit counting, makes that its performance is more stable, cost is lower.Add treatment on special problems function, compared to other counting assemblys, accuracy is higher.
Obviously; above-described embodiment of the present utility model is only for the utility model example is clearly described; and be not the restriction to embodiment of the present utility model; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here cannot give exhaustive to all embodiments, every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
