Abstract
The utility model discloses an energy conservation control system for an escalator. The energy conservation control system comprises a photoelectric switch arranged at an escalator entrance, the output end of the photoelectric switch is connected with the input end of a controller, the output end of the controller is connected with one input end of a frequency changer, the output end of the frequency changer is connected with an escalator motor, and the other input end of the frequency changer is electrically connected with a power grid. The energy conservation control system can reduces unnecessary energy consumption of the no-load escalator. Due to the fact that the running rate of the escalator is reduced, abrasion of running mechanical components is reduced, the service life is greatly improved, and maintenance cost and cost for replacing parts are reduced.
Description
Technical field
The utility model is applied to the control field of escalator, relates to the control system of escalator, particularly a kind of energy-saving control system of escalator.
Background technology
Due to the particularity of escalator field of employment, it must keep long operation.But no matter whether most having the passenger with escalator, as long as be in all the time the running state of command speed once starting shooting, can cause like this escalator system power consumption greatly, the shortcoming such as mechanical part serious wear, service life be short.
The utility model content
The purpose of this utility model is, a kind of energy-saving control system of escalator is provided.It not only can reduce the energy consumption of escalator system, can also reduce the wearing and tearing of mechanical part, improves the service life of mechanical part.
The technical solution of the utility model: a kind of energy-saving control system of escalator, comprise the photoelectric switch that is located at the elevator entrance place, the mouth of photoelectric switch connects the input end of controller, the mouth of controller connects an input end of frequency converter, the mouth of frequency converter connects the escalator electrical motor, and another input end of frequency converter is electrically connected to electrical network.
The energy-saving control system of aforesaid escalator, frequency converter comprise rectifier, dc bus and inverter, and the input end of rectifier is electrically connected to electrical network, and the mouth of rectifier is electrically connected to inverter through dc bus.
The energy-saving control system of aforesaid escalator, the two-way connection inverter of escalator electrical motor, the two-way connection dc bus of inverter, the two-way power conversion unit that is connected with of dc bus, the two-way storage battery that is connected with in power conversion unit.
Compared with prior art, the utility model has formed a kind of energy-saving control system of escalator by photoelectric switch, controller, frequency converter, escalator electrical motor.The utility model is installed photoelectric switch in the entrance of escalator, when the passenger is arranged, photoelectric switch sends signal, the controller of escalator is controlled frequency converter timing to command speed, after whole passengers leave escalator, controller controls again that escalator enters low cruise or halted state is received guests, can reduce like this staircase unnecessary energy consumption when unloaded, because the elevator operating rate reduces, can reduce the wearing and tearing of operation mechanical part, greatly improved service life, reduced the expense of maintenance and replacing spare and accessory parts.
AT STATION, the crowded place such as market, be generally two escalators inverted running side by side.When the fully loaded operation downwards of escalator, due to escalator self and passenger's gravitional force impact, electrical motor can enter reproduced state.Passenger capacity is more, and the regenerated energy that gravitional force produces is larger.Add storage battery to carry out the storage of braking energy in escalator system, thereby regenerated energy is utilized, can reach better energy-conservation effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
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 energy-saving control system of escalator, form as shown in Figure 1, comprise the photoelectric switch 1 that is located at the elevator entrance place, the mouth of photoelectric switch connects the input end of controller 2, the mouth of controller 2 connects an input end of frequency converter 3, the mouth of frequency converter 3 connects escalator electrical motor 7, and another input end of frequency converter 3 is electrically connected to electrical network 10.
The two-way connection inverter 6 of escalator electrical motor 7, the two-way connection dc bus 5 of inverter 6, the two-way power conversion unit 3 that is connected with of dc bus 5, the two-way storage battery 9 that is connected with in power conversion unit 3.
Photoelectric switch 1 is placed in the elevator entrance place for detection of whether having the passenger to enter staircase.If enter, the signal that sets out sends to controller 2.Photoelectric switch 1 can be MGK series photoelectric switch.Controller 2 can be ZY-F staircase microcomputerized controller.
The effect of inverter 6 is to produce the frequency of controlling escalator electrical motor 7 voltages, and inverter 6 becomes direct current (DC) another mistake into alternating current (straight-alternation changes).
When the escalator heavy duty is descending, impact due to gravitional force, the electrical motor of escalator is in the generator operation operating mode, and escalator electrical motor 7 feeds back to dc bus 5 with feedback energy by inverter 6, and dc bus 5 stores energy in 9 li of storage batterys by power conversion unit 8.The energy in storage battery 9 can be used for the partial illumination in market, thereby reaches the purpose of the renewable sources of energy.Storage battery is as traditional apparatus for storing electrical energy, and its advantage is mature and reliable, and is compared to the energy storage device of super capacitor, and the price that unit of electrical energy stores is very cheap.
Principle of work of the present utility model: photoelectric switch is installed in the entrance at escalator, when the passenger is arranged, photoelectric switch sends signal, the controller of escalator is controlled frequency converter timing to command speed, after whole passengers leave escalator, controller controls again that escalator enters low cruise or halted state is received guests, can reduce like this staircase unnecessary energy consumption when unloaded, because the elevator operating rate reduces, can reduce the wearing and tearing of operation mechanical part, greatly improved service life, reduced the expense of maintenance and replacing spare and accessory parts.
