Abstract

The utility model discloses an automatic escalator energy saving device which comprises a starting trigger arranged at the position of an inlet of an automatic escalator. The output end of the starting trigger is connected with the input end of a control chip, and the output end of the control chip is connected with a frequency conversion controller of the automatic escalator. Compared with the prior art, the starting trigger is arranged at the position of the inlet of the automatic escalator to detect whether passengers are on the automatic escalator. When a detecting feedback is that no requirement of personnel occupation exists, the system controls the automatic escalator to perform low speed standby operation. Under the condition that practical use efficiency of the escalator is not influenced, strong electricity energy required by forcing operation is saved. In addition, the automatic escalator energy saving device reduces unnecessary mechanical abrasion, prolongs service life of the automatic escalator, and can reduce maintenance cost used by the system.

Description

A kind of escalator energy saver

Technical field

The utility model relates to a kind of energy saver, particularly a kind of escalator energy saver.

Background technology

Present most of escalator is to run without interruption by the single speed of predetermined direction, no matter on the escalator treadboards whether the passenger is arranged, escalator all runs without interruption with this speed always, not only waste a large amount of electric power resources, but also make escalator be in wear state always, reduced the service life of escalator, the maintenance cost of escalator also relatively can be than higher.

The utility model content

The purpose of this utility model is, a kind of escalator energy saver is provided.It can cut down the consumption of energy, and reduces cost, the service life that can also improve escalator.

The technical solution of the utility model: a kind of escalator energy saver, comprise the startup binary pair that is located at place, escalator gangway, start the input end that the binary pair mouth is connected with control chip, the mouth of control chip is connected with clock circuit, and the mouth of control chip connects the frequency-variable controller of escalator.

In the aforesaid escalator energy saver, described startup binary pair is pressure sensor or the electric switch that diffuses.

In the aforesaid escalator energy saver, described control chip is PLC.

In the aforesaid escalator energy saver, described clock circuit is clock chip.

Compared with prior art, the utility model is by starting binary pair to detect on the escalator whether the passenger is arranged in place, escalator gangway peace, can be when detection be fed back to no personnel and takies demand, system's control escalator is done the operation of standby at a slow speed, under the prerequisite of the actual service efficiency that does not influence staircase, saved the required powerful electric energy of forced service, and the utility model has reduced unnecessary mechanical wear, prolonged the service life of escalator, the maintenance cost of can mitigation system using.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Being labeled as in the accompanying drawing: the 1-pedal, 2-starts binary pair, 3-control chip.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.

Embodiment.A kind of escalator energy saver constitutes as shown in Figure 1, comprises the startup binary pair 2 that is located at place, escalator gangway, and the mouth that starts binary pair 2 is connected with the input end of control chip 3, and the mouth of control chip 3 connects the frequency-variable controller of escalator.Start binary pair 2 and be pressure sensor or the electric switch that diffuses, control chip 3 is PLC.

Start binary pair 2 and be installed on the pedal supporting seat in escalator entrance or exit, be placed on other and can sense the position that the passenger goes into ladder and all can.Pressure sensor can be the PY206 pressure sensor.The electric switch that diffuses can be A3R-30X diffuser reflection switch.When the passenger entered pedal 1, the current potential that starts binary pair 2 changed, and transmitted electric signal to control chip 3.

Control chip 3 is PLC, can be model QT1692.Control chip 3 is behind the electric signal that reception startup binary pair 2 sends, send the staircase assisted instruction to the escalator frequency-variable controller, start timing function simultaneously, what this timing function calculated is escalator time of run from the inlet to the outlet, can set in advance according to the running condition of escalator, such as being set at N minute according to actual run time, when escalator arrives outlet from beginning to accelerate mobile operation after N minute, clocking capability stops, this moment, control chip 3 sent a reply instruction to the escalator frequency-variable controller again, escalator is returned to accelerates preceding running state.After once acceleration enabled instruction meeting cover previous assisted instruction, if escalator had both been arranged on two people front and back, the instruction that escalator sent when a back people came up can override the last individual instruction that escalator sends when coming up.Control chip 3 can be the FX2N of Mitsubishi.

Principle of work: when the startup binary pair 2 that is installed in the escalator entrance has not detected the stream of people in the certain zone of entrance, escalator is in energy-saving run state at a slow speed, when the people enters surveyed area, ladder priming inductor 2 transmits signals to control chip 3, control chip 3 sends the staircase assisted instruction to frequency-variable controller, the suitable running velocity of frequency-variable controller control escalator output, control chip 3 starts timing function simultaneously.Arrive outlet after N minute when escalator begins to accelerate to move operation from entrance, clocking capability stops, and this moment, control chip 3 sent a reply instruction to the escalator frequency-variable controller again, made the running state before escalator is returned to acceleration.

It starts binary pair 2 to detect passenger flow volume by installing at place, escalator gangway, can make when detection is fed back to no personnel and takies demand, system's control escalator is done the operation of standby at a slow speed, under the prerequisite of the actual service efficiency that does not influence staircase, saved the required powerful electric energy of forced service, and the utility model reduced unnecessary mechanical wear, prolonged the service life of staircase, alleviated the maintenance cost that system uses.
