Description

Elevator power saving energy-saving control system and method thereof

The invention relates to an elevator energy-saving energy-saving control system and a method thereof, in particular to a technician capable of achieving energy-saving elevator electromechanical control.

The elevator control system generally known is to control the lifting operation of the elevator, the opening and closing of the elevator door panel on each floor, and the display information of the floor where the elevator is located. In addition, the elevator signal of each floor button can be accepted, so as to control the elevator to be suspended on the floor, so that the user can ride the elevator to reach the upper and lower floors.

In general, the conventional elevator control system does not have the relevant function setting for power saving, so the information display state of the elevator display panel is always maintained at a high brightness state at any time of the day, and therefore, the unmanned peak Illuminating the elevator display panel during the period does cause unnecessary waste of electrical energy. Furthermore, in the conventional elevator system, there is no effective adjustment and management of the entire set of elevators, and it is impossible to automatically capture the elevator use frequency record as the basis for power supply adjustment of each device in the elevator system, so that the entire elevator The system is in any state of power consumption. In particular, the elevator system includes display panels, main motors and inverters, brakes, compartments and adjacent lighting, cabin fans, communication and emergency backup power, which cannot be managed. Underneath, it is extremely energy-intensive, and the elevators on the high floors are more serious. Due to the elevator system during the day, in addition to the peak period (such as off-duty hours) and near the peak period, the late night or early morning can be regarded as the peak period, the number of people using the elevator during the peak period may be relatively reduced, and some floors Due to the small number of households or other reasons, it is rarely used. If the elevator is used by a small number of people, its electrical equipment will continue to use electricity for unnecessary operations, such as display panels, if it is not managed or regulated. Continued to maintain normal high brightness, the brakes remain activated and the cabin lighting maintains high-brightness lighting and the cabin fan remains operational, resulting in significant power wastage. Therefore, how to develop a set of elevator control technology that can identify the peak period and the peak period, and can be used as the power-saving basis according to the number of uses has become an urgent problem and challenge for the industry in the same field.

According to the pre-patent case related to the present case, such as the domestic new type 545481 "automatic modulation device for elevator display screen", it is provided with a light sensor on the elevator display screen to detect the light source state of the floor. And adjust the brightness of the elevator display screen according to the light source status of the floor. Although the patent can adjust the brightness of the elevator display screen according to the on-site light source to achieve the power saving effect; however, the patent is still the same as the aforementioned conventional structure, and the elevator display panel is always maintained at a certain time at any time of the day. Within the brightness range, the difference between the two is only that the patent can make a limited brightness adjustment. Therefore, in the unmanned peak period, the patented elevator display panel is still lit, so it still causes There is no need to waste power, so the patent still needs to be improved. In view of the above, the present invention proposes a set of the present invention which can improve the lack of efficient power saving of conventional elevator equipment.

The main object of the present invention is to provide an elevator energy-saving energy-saving control system and a method thereof, which mainly recognize the elevator usage period as a peak or a peak state according to the frequency of the elevator use, and then use the number of times of each period as the elevator equipment. The power supply rate adjustment of the electric device is based on the purpose of avoiding the occurrence of electric energy consumption due to idling and standby idleness of the electric equipment of the elevator equipment, thereby achieving the purpose of saving electric energy. The technical means for achieving the above objective is to connect the electrical connection control device of the electromechanical control system of the elevator device to control the power supply rate of the electric device of the elevator device, and the control device comprises an experience collecting and recording device, a signal processing unit and At least one drive unit. The experience collection and recording device can sequentially capture the opening and closing signals of the opening and closing of the door panel of the elevator equipment during the divided time period. The signal processing unit is configured to accumulate the opening and closing signal for each time period as a value, and set a control signal when the number of times is less than at least a predetermined value. The driving unit is triggered by the control signal to reduce the power supply rate of the power-receiving device to at least a proportional value, thereby achieving the power saving effect of the elevator.
