Description

Technical Field

[0001] The present invention belongs to the technical field of energy-saving control, and particularly relates to an energy-saving control device, system and method for an elevator operating without load. Background Art

[0002] Passenger elevators are intelligent and automated devices controlled by microcomputers, and do not require special personnel to operate. For the elevator structure diagram and the internal structure diagram of the elevator, ordinary passengers only need to take and operate the elevator according to the correct procedures.

[0003] Among them, passenger elevators have the following operating modes: ① Low-peak mode: Enter the low-peak mode when traffic is sparse. ② Normal mode: The elevator operates according to the "psychological waiting time" or "maximum-minimum" principle. ③ Upward peak: During the morning peak time, all elevators drive towards the main floor to avoid congestion. ④ Midday service: Strengthen the service on the restaurant floor. ⑤ Downward peak: During the evening peak period, strengthen the service on the crowded floors. When entering the low-peak mode when traffic is sparse, the elevator often runs without load to the first floor and stops, waiting for passengers to use.

[0004] When a relatively large number of existing elevators stop at the first floor waiting for passengers to use, the elevator doors are often in the open state, and moreover, various internal devices (such as ventilation, lighting, etc.) are all in the open state. At this time, the elevator is in a state of being unused (i.e., without passengers), resulting in energy consumption of long-term operation of the devices. Especially at night, almost no one uses the elevator, and various devices operate ineffectively all night. In addition to the energy consumption problem, there is also a risk of device aging or even damage, etc.

[0005] Therefore, at the present stage, it is necessary to design an energy-saving control device, system and method for an elevator operating without load to solve the above problems. Summary of the Invention

It should be noted that relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0048] Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0049] As Figure 1 shown, an energy-saving control device for the no-load operation of an elevator is proposed, which includes lighting equipment, ventilation equipment, advertising audio equipment, advertising video equipment, and also includes a human proximity detection device, an infrared ranging device, a position detection device, a face orientation detection device, and a main control device; the main control device is respectively connected to the lighting equipment, ventilation equipment, advertising audio equipment, advertising video equipment, human proximity detection device, infrared ranging device, position detection device, and face orientation detection device;

[0050] The human proximity detection device is used to detect whether there is a passenger within the range of the first distance threshold from the elevator door;

[0051] The infrared ranging device is used to detect whether there is a passenger within the range of the second distance threshold from the elevator door;

[0052] The position detection device is used to detect whether there is a passenger within the range of the third distance threshold from the elevator door;

[0053] The facial orientation detection device is used to detect the facial orientation of passengers in the elevator car and determine whether the facial orientation points to the location of the advertising video device;

[0054] Wherein, when the passenger is within the range of the third distance threshold from the elevator door, the passenger can just hear the audio information of the advertising audio device;

[0055] The first distance threshold is greater than the second distance threshold, and the second distance threshold is greater than the third distance threshold.

[0056] Further, as Figure 2 shown, the main control device controls the human body proximity detection device to be always on, and controls the lighting device, ventilation device, advertising audio device, advertising video device, infrared ranging device, position detection device, and facial orientation detection device to be normally closed;

[0057] When the human body proximity detection device detects that there is a passenger within the range of the first distance threshold from the elevator door, the main control device controls the lighting device and the infrared ranging device to be turned on;

[0058] When the infrared ranging device detects that there is a passenger within the range of the second distance threshold from the elevator door, the main control device controls the ventilation device and the position detection device to be turned on;

[0059] When the position detection device detects that there is a passenger within the range of the third distance threshold from the elevator door, the main control device controls the advertising audio device and the facial orientation detection device to be turned on;

[0060] When the facial orientation detection device determines that the facial orientation points to the location of the advertising video device, the main control device controls the advertising video device to be turned on.

[0061] In the above solution, through the orderly cooperation start of the lighting device, ventilation device, advertising audio device, advertising video device, human body proximity detection device, infrared ranging device, position detection device, and facial orientation detection device, it is possible to avoid too many devices being in an ineffective working state for a long time, reduce the energy consumption of the entire elevator operation, and achieve the purpose of energy saving; and, by adjusting the distance of the passenger from the elevator door to three levels through the human body proximity detection device, infrared ranging device, and position detection device, and turning on the corresponding devices according to the actual distance of the passenger from the elevator door, the energy saving of the devices can be refined to the maximum benefit; and, through the facial orientation detection device, it is possible to determine whether the passenger is watching the video, so as to determine whether to turn on the video, further achieving energy saving.

[0062] Further, it further includes a passenger height detection device and a video device adjustment device;

[0063] The passenger height detection device and the video device adjustment device are respectively connected to the main control device;

[0064] The passenger height detection device is used to detect the height data of passengers in the elevator car and determine whether the height data reaches a preset height range;

[0065] The video device adjustment device is used to adjust the height of the advertising video device in the elevator car or to adjust the display screen of the advertising video device to deflect downward.

[0066] Furthermore, the main control device controls the passenger height detection device and the video device adjustment device to be normally closed;

[0067] When the main control device controls the advertising video device to be turned on, the main control device simultaneously controls the passenger height detection device to be turned on;

[0068] When the passenger height detection device determines that the height data does not reach the preset height range, the main control device controls the video device adjustment device to be turned on.

[0069] In the above solution, in actual application, we found that there are passengers with relatively low height, and they need to raise their heads when watching video advertisements, resulting in relatively low head comfort for passengers; therefore, through the cooperation of the passenger height detection device and the video device adjustment device, the viewing experience of passengers with relatively low height can be effectively guaranteed.

[0070] Furthermore, the video device adjustment device includes a video device lifting device and a video device rotating device;

[0071] The video device lifting device and the video device rotating device are respectively connected to the main control device;

[0072] The video device lifting device is used to lift and adjust the height of the advertising video device in the elevator car;

[0073] The video device rotating device is used to adjust the display screen of the advertising video device to deflect downward.

[0074] Furthermore, an image detection and recognition device is also included;

[0075] The image detection and recognition device is connected to the main control device;

[0076] The main control device controls the image detection and recognition device to be normally closed;

[0077] When the main control device controls the advertising video device to be turned on, the main control device simultaneously controls the image detection and recognition device to be turned on;

[0078] When the image detection and recognition device detects and recognizes that a passenger is sitting in a wheelchair, the main control device simultaneously controls the lifting device and the rotating device of the video device to turn on.

[0079] In the above solution, in practical applications, we found that when there are passengers sitting in wheelchairs, only turning on one of the lifting device or the rotating device of the video device still cannot guarantee the video viewing experience of such passengers. Therefore, the lifting device and the rotating device of the video device are turned on simultaneously to guarantee the experience of such passengers.

[0080] Furthermore, it further includes an audio device adjustment device, and the audio device adjustment device is connected to the main control device;

[0081] When the image detection and recognition device detects and recognizes that there is a baby among the passengers and the baby is asleep, the main control device controls the audio device adjustment device to turn on, and the audio device adjustment device adaptively reduces the volume of the advertising audio device.

[0082] In the above solution, in practical applications, we found that there are babies among the passengers and the babies are asleep. In order to ensure the sleep of the babies and avoid waking them up, the volume of the advertising audio device is adaptively reduced in cooperation with the audio device adjustment device.

[0083] As Figure 3 shown, an energy-saving control system for an elevator running without load is proposed, which includes an energy-saving control device for an elevator running without load as described above, and further includes a wireless communication device and a remote monitoring center;

[0084] The main control device is connected to the remote monitoring center through the wireless communication device.

[0085] In the above solution, the energy-saving control device communicates with the remote monitoring center through the wireless communication device, and remote data interaction can be realized.

[0086] An energy-saving control method for an elevator running without load is proposed, and an energy-saving control device for an elevator running without load as described above is used for energy-saving control.
