Abstract

The utility model relates to an energy-saving escalator control system which comprises an infrared induction triggering circuit No.1, an infrared induction triggering circuit No.2, a singlechip control circuit, a control drive circuit and a voice warning circuit, wherein the output ends of the induction triggering circuits No.1 and No.2 are connected with the singlechip control circuit; and the output of the singlechip control circuit is connected with the control drive circuit and the voice warning circuit. The system adopts infrared to induct infrared rays of human bodies, so as to judge whether somebody enters the escalator from the entrance of the escalator or not and whether somebody still glides in the middle the escalator or not; when nobody is on the escalator according to the synthetic judgment, the power supply of the escalator is stopped; and when somebody takes the escalator through induction, an escalator motor is then started to operate, so that energy is saved, and the escalator taking of people can not be influenced. As children taking the escalator are warded by adults, in order to avoid accidents, the voice circuit is arranged to remind people taking the escalator of protecting the safety of the children.

Description

A kind of energy-saving electric staircase control system

Technical field

The utility model relates to the escalator field, particularly relates to a kind of energy-conservation escalator control system.

Background technology

The vehicle of a kind of shipper and article during escalator, be widely used in the intensive public places of personnel such as megastore, exhibition center, hotel, station, hospital, bring very big convenience to people, but escalator does not have the manned running state that all is in regardless of having, and consumed power is very big, in some place, the degree of utilization of escalator is very low, the escalator most of the time in these places, no-load ratio caused a large amount of waste of energy more than 50% sometimes no-load run (not having the passenger).

The utility model content

It is human body infrared that the purpose of this utility model provides a kind of employing infrared induction, judges and restart the operation of staircase electrical motor, the escalator control system of practical energy-conservation purpose when staircase has the passenger.

The technical scheme that the utility model adopted is such: a kind of energy-saving electric staircase control system, comprise infrared No. 1 sensor trigger circuit, No. 2 sensor trigger circuits, single chip machine controlling circuit, control Driver Circuit, voice alarm circuit, the mouth of described No. 1 sensor trigger circuit and No. 2 sensor trigger circuits is connected single chip machine controlling circuit, and single chip machine controlling circuit output connects control Driver Circuit and voice alarm circuit.

Be connected to the base stage of aerotron after the mouth series resistance that described No. 1 sensor trigger circuit and No. 2 sensor trigger circuits are the pyroelectric infrared-sensing module, No. 1 sensor trigger circuit is installed in staircase inflow point, and No. 2 sensor trigger circuits are installed in place in the middle of the staircase.

Described pyroelectric infrared-sensing module adopts the BH9402 module.

By adopting the aforementioned techniques scheme; the beneficial effects of the utility model are: this system's employing infrared induction is human body infrared judges whether the someone enters staircase to the staircase inlet; whether the centre has the people also to slide at staircase; when comprehensively judging nobody; allow staircase stop power supply; when induction has the people to take advantage of; restart the operation of staircase electrical motor; be energy-conservationly not influence people again and take advantage of a staircase like this; owing to take advantage of the child of a staircase to guard by the adult; for fear of having an accident, be provided with sound circuit and remind the people that take advantage of a staircase to note protecting child's a safety of taking advantage of.

Description of drawings

Fig. 2 is the schematic circuit diagram of the utility model embodiment.

The specific embodiment

Further specify the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, a kind of energy-saving electric staircase control system, comprise infrared No. 1 sensor trigger circuit 1, No. 2 sensor trigger circuits 2, single chip machine controlling circuit 3, control Driver Circuit 4, voice alarm circuit 5, the mouth of described No. 1 sensor trigger circuit 1 and No. 2 sensor trigger circuits 2 is connected single chip machine controlling circuit 3, single chip machine controlling circuit 3 outputs connect control Driver Circuit 4 and voice alarm circuit 5, described No. 1 sensor trigger circuit 1 and No. 2 sensor trigger circuits 2 are for being connected to the base stage of aerotron after the mouth series resistance of pyroelectric infrared-sensing module, No. 1 sensor trigger circuit 1 is installed in staircase inflow point, No. 2 sensor trigger circuits 2 are located in the middle of being installed in staircase, and described pyroelectric infrared-sensing module adopts the BH9402 module.

As shown in Figure 2, No. 1 sensor trigger circuit connects resistance R 1 by the CP end of No. 1 pyroelectric infrared-sensing module I C1, behind the aerotron Q1, be delivered to the P1 point by resistance R 3, No. 2 sensor trigger circuits connect resistance R 2 by the CP1 end of No. 2 pyroelectric infrared-sensing module I C1, behind the aerotron Q2, be delivered to the P2 point by resistance R 4, advance man-hour as the people, No. 1 pyroelectric infrared-sensing module I C1 promptly is triggered, its CP end output pulse width is the high level of 2 one 5S, aerotron Q1 conducting, as long as it is movable a little that human body continues in the module monitors zone, the just continuous output signal of CP end of No. 1 pyroelectric infrared-sensing module I C1, this signal P1 is input to the 36th pin I/O end of single chip machine controlling circuit IC3, and single chip machine controlling circuit IC3 is after internal processes comprehensively is judged as normal operation, the 28th pin output low level signal by single chip machine controlling circuit IC3, make aerotron Q4 conducting through resistance R 10, the relay J adhesive, switch J1-1 is by becoming normally closed point normal battle, promote motor operation, the staircase operation.P1 point signal is input to single chip machine controlling circuit IC3 the 36th pin I/O end, IC1 the 2nd pin output low level signal, make aerotron Q3 conducting through resistance R 9, make 9561 alarm chip IC4 obtain power supply voltage, 9561 alarm chip IC4 the 2nd pin output audio alert signal, output to LM386 audio amplifier IC5 the 3rd pin through capacitor C 2 couplings, after internal audio frequency amplifies, send audio alert through LM386 audio amplifier IC5 the 6th pin output capacitance C1 coupling amplification promotion buzzer phone Y again and " please guard your child ", reminds people is to children's nurse.As No. 1 pyroelectric infrared-sensing module I C1 that is installed in staircase inflow point, do not sense when human body infrared, aerotron Q1 is in off condition, simultaneously No. 2 pyroelectric infrared-sensing module I C2 do not sense in specific time when human body infrared, when aerotron Q2 also is in off condition, acquired signal P1, the P2 point is input to the 36th pin of single chip machine controlling circuit IC3 and the I/O end of 25 pin respectively, single chip machine controlling circuit IC3 is through the internal processes logic control, the 28th pin output high level signal by single chip machine controlling circuit IC3, through resistance R 10 aerotron Q4 is ended, the relay J adhesive, switch J1-1 becomes normal battle by normally closed point, the electrical motor dead electricity is shut down, and staircase in operation, does not reach purpose of energy saving.
