Detailed Embodiments

[0020] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0022] Figure 1 The flowchart of an automatic energy-saving method for a video terminal in an elevator according to the present invention is shown.

[0023] As Figure 1 shown, the present invention discloses an automatic energy-saving method for a video terminal in an elevator, including: S102, obtaining an elevator signal and a digital signal; S104, analyzing according to the elevator signal and the digital signal to determine whether the elevator meets a first preset energy-saving condition; S106, if so, controlling the video terminal to enter a first-level energy-saving mode; if not, maintaining the normal mode; S108, determining whether the video terminal meets a second preset energy-saving condition in the first-level energy-saving mode; S110, if so, controlling the video terminal to enter a second-level energy-saving mode; if not, maintaining the first-level energy-saving mode; S112, in the first-level energy-saving mode or the second-level energy-saving mode, if the elevator does not meet the first preset energy-saving condition, the video terminal enters the normal mode.

[0024] According to an embodiment of the present invention, the elevator signal and the digital signal are respectively obtained through an elevator system and a micro motion sensor, and are transmitted to the video terminal through the elevator system and the micro motion sensor. The first preset energy-saving condition is that the elevator is not in an operating state and there is no person in the elevator. When the current elevator meets the first preset energy-saving condition, the video terminal automatically enters the first-level energy-saving mode, reduces the brightness of the display screen and starts timing, so as to determine whether the video terminal meets the second preset energy-saving condition. Among them, the second preset energy-saving condition is that the duration of the video terminal entering the first-level energy-saving mode is approximately a first preset threshold, and the first preset threshold is 3 min. In addition, after the video terminal enters the energy-saving mode, the elevator signal and the digital signal are continuously analyzed. If the elevator enters the operating state or the micro motion sensor detects someone, the video terminal immediately exits the energy-saving mode and switches to the normal mode, turns on the display screen, and adjusts the brightness of the display screen to the normal brightness.

[0025] According to an embodiment of the present invention, it further includes: The elevator system collects the elevator signal and sends the elevator signal to the video terminal; The elevator signal includes a call signal, a motor operation signal, and a door opening / closing signal.

[0026] It should be noted that the elevator system collects elevator signals generated during the operation of the elevator, including call signals, motor operation signals, door opening and closing signals, etc. The elevator system transmits the collected elevator signals to the video terminal through the in-bridge line method.

[0027] According to an embodiment of the present invention, it further includes: The micro motion sensor monitors the objects inside the elevator in real time; When the micro motion sensor detects the movement of an object inside the elevator, it outputs an IO voltage signal; The micro motion sensor converts the voltage signal into a digital signal and sends it to the video terminal.

[0028] It should be noted that a micro motion sensor is provided in the elevator car. The micro motion sensor uses a radar induction module and applies Doppler technology. When the radio wave vibration source and the observer move relative to each other at a relative speed V, the vibration frequency received by the radar induction module is different from the frequency emitted by the vibration source, so as to determine the movement of the object. When an object moves, an IO voltage signal is output, and then the IO voltage signal is converted into a digital signal and sent to the video terminal. The micro motion sensor transmits the digital signal to the video terminal in a wired or wireless manner.

[0029] Figure 2 The flowchart of a method for a video terminal inside an elevator to enter the first-level energy-saving mode according to the present invention is shown.

[0030] As Figure 2 shown, according to an embodiment of the present invention, analyzing according to the elevator signal and the digital signal to determine whether the elevator meets the first preset energy-saving condition includes: S202, the video terminal analyzes according to the triggering situation of the elevator signal within the first preset time to obtain the elevator operation state information; S204, if not triggered, the elevator is in an unoperated state; if triggered, the elevator is in an operating state; S206, the video terminal analyzes according to the digital signal to obtain whether there is personnel information inside the elevator; S208, the video terminal analyzes according to the elevator operation state information and whether there is personnel information inside the elevator; S210, if the elevator is in an unoperated state and there is no personnel inside the elevator within the second preset time, the brightness of the video terminal display screen is adjusted to make the video terminal enter the first-level energy-saving mode.

[0031] It should be noted that the video terminal analyzes the received elevator signal and digital signal respectively. First, it analyzes the elevator signal to obtain the elevator operation status information. After obtaining the elevator operation status information, it then analyzes the digital signal to obtain whether there are people in the elevator in the non-operating state of the elevator, so as to judge whether there are people in the elevator in the non-operating state of the elevator, and thus judge whether to control the video terminal to enter the first energy-saving mode. Among them, the first preset energy-saving condition is that the elevator is in the non-operating state and there are no people in the elevator. When the first preset energy-saving condition is met, the video terminal automatically enters the first-level energy-saving mode, reducing the brightness of the video terminal display screen to make the display screen darker. Among them, both the first preset time and the second preset time are 30S, which can be adjusted according to actual needs.

[0032] Figure 3 The flowchart of a method for a video terminal in an elevator to enter the second-level energy-saving mode according to the present invention is shown.

[0033] As Figure 3 shown, according to an embodiment of the present invention, determining whether the video terminal meets the second preset energy-saving condition in the first-level energy-saving mode includes: S302, obtaining the time information when the video terminal enters the first-level energy-saving mode; S304, judging whether the time information is greater than the first preset threshold; S306, if so, controlling the video terminal to enter the second-level energy-saving mode; otherwise, doing nothing.

[0034] It should be noted that when the video terminal enters the first-level energy-saving mode, a timing device is started. The timing device is used to record the time when the video terminal enters the first-level energy-saving mode. Among them, the first preset threshold is 3 minutes, which can be adjusted by the user according to their own needs. When the time information when the video terminal enters the first-level energy-saving mode is greater than the first preset threshold, that is, the second preset energy-saving condition is met, the video terminal automatically enters the second-level energy-saving mode, turns off the display screen, makes the screen enter the sleep state, and turns off the speaker, so that the video terminal is in a state of maintaining the most basic functions, that is, the standby state.

[0035] According to an embodiment of the present invention, in the first-level energy-saving mode or the second-level energy-saving mode, if the elevator does not meet the first preset energy-saving condition, the video terminal enters the normal mode, including: The video terminal analyzes the elevator operation status information and whether there are people in the elevator in the energy-saving mode; If the elevator is in the operating state and / or there are people in the elevator, the video terminal switches from the energy-saving mode to the normal mode.

[0036] It should be noted that the energy-saving mode includes a primary energy-saving mode and a secondary energy-saving mode. In the energy-saving mode, when the elevator receives elevator signals (call signals, motor operation signals, door opening and closing signals), it enters the operating state. At the same time, the video terminal in the elevator exits the energy-saving mode, switches to the normal mode, turns on the display screen and adjusts the brightness of the display screen to the normal brightness. Similarly, when the micro motion sensor detects a person, the video terminal in the elevator is switched from the energy-saving mode to the normal mode.

[0037] Figure 4 The block diagram of an automatic energy-saving and power-saving system for a video terminal in an elevator according to the present invention is shown.

The memory includes an automatic energy-saving and power-saving method program for the video terminal in the elevator. When the automatic energy-saving and power-saving method program for the video terminal in the elevator is executed by the processor, the following steps are implemented: Obtain elevator signals and digital signals; Analyze according to the elevator signals and digital signals to determine whether the elevator meets the first preset energy-saving condition; If so, control the video terminal to enter the primary energy-saving mode; if not, maintain the normal mode; Judge whether the video terminal meets the second preset energy-saving condition in the primary energy-saving mode; If so, control the video terminal to enter the secondary energy-saving mode; if not, maintain the primary energy-saving mode; In the primary energy-saving mode or the secondary energy-saving mode, if the elevator does not meet the first preset energy-saving condition, the video terminal enters the normal mode.

[0039] According to the embodiments of the present invention, the elevator signals and digital signals are respectively obtained through the elevator system and the micro motion sensor, and are transmitted to the video terminal through the elevator system and the micro motion sensor. The first preset energy-saving condition is that the elevator is not in the operating state and there is no person in the elevator. When the current elevator meets the first preset energy-saving condition, the video terminal automatically enters the primary energy-saving mode, reduces the brightness of the display screen and starts timing, so as to judge whether the video terminal meets the second preset energy-saving condition. Among them, the second preset energy-saving condition is that the duration for which the video terminal enters the primary energy-saving mode is approximately the first preset threshold, and the first preset threshold is 3 min. In addition, after the video terminal enters the energy-saving mode, the elevator signals and digital signals are continuously analyzed. If the elevator enters the operating state or the micro motion sensor detects someone, the video terminal immediately exits the energy-saving mode and switches to the normal mode, turns on the display screen, and adjusts the brightness of the display screen to the normal brightness.

[0040] According to the embodiments of the present invention, it further includes: The elevator system collects elevator signals and sends the elevator signals to a video terminal; The elevator signals include call signals, motor operation signals, and door opening / closing signals.

[0041] It should be noted that the elevator system collects elevator signals generated during the operation of the elevator, including call signals, motor operation signals, door opening / closing signals, etc. The elevator system transmits the collected elevator signals to the video terminal through the in-bridge line.

[0043] It should be noted that a micro motion sensor is provided in the elevator car. The micro motion sensor uses a radar induction module and applies the Doppler technology. When the radio wave vibration source and the observer move relative to each other at a relative speed V, the vibration frequency received by the radar induction module is different from the frequency emitted by the vibration source, so as to determine the movement of the object. When an object moves, an IO voltage signal is output, and then the IO voltage signal is converted into a digital signal and sent to the video terminal. The micro motion sensor transmits the digital signal to the video terminal in a wired or wireless manner.

[0044] According to an embodiment of the present invention, analyzing according to the elevator signals and digital signals to determine whether the elevator meets the first preset energy-saving condition includes: The video terminal analyzes according to the triggering situation of the elevator signals within the first preset time to obtain elevator operation state information; If not triggered, the elevator is in an unoperated state; if triggered, the elevator is in an operating state; The video terminal analyzes according to the digital signal to obtain whether there is personnel information inside the elevator; The video terminal analyzes according to the elevator operation state information and whether there is personnel information inside the elevator; If the elevator is in an unoperated state and there is no personnel inside the elevator within the second preset time, the brightness of the video terminal display screen is adjusted to make the video terminal enter the first-level energy-saving mode.

[0045] It should be noted that the video terminal analyzes the received elevator signal and digital signal respectively. First, the elevator operation status information is obtained through the analysis of the elevator signal. Then, when the elevator is in the non-operating state, the information on whether there are people in the elevator is obtained through the analysis of the digital signal, so as to judge whether there are people in the elevator in the non-operating state of the elevator, and thus judge whether to control the video terminal to enter the first energy-saving mode.
