The terms "first", "second" and "first" are used merely for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "plurality" is two or more unless specifically limited otherwise.

Referring to fig. 1 to 3, an elevator control system 100 for an elevator is provided according to an embodiment of the present application. The elevator comprises a plurality of hall call boxes 2, which are respectively arranged outside the landing door 7 of each floor, usually on the wall on one side of the landing door 7. Referring to fig. 1, a part of the outbound box 2 is used as a display screen 21 for displaying the operation information of the elevator, such as the floor where the current car 8 operates is indicated in a digital manner, and call buttons 22 (including an up button and a down button, for a special floor such as a terminal floor, only the up button or the down button may be provided) are provided on the other part, and each call button 22 is connected with the main control panel 1. When the user presses at least one of the buttons (e.g., the lower row button), the indicator lights (not shown) around the button also turn on, indicating that call information has been input to the main control panel 1 at this time.

In this embodiment, as shown in fig. 1, the elevator control system 100 includes a main control board 1, a plurality of hall boxes 2, and a plurality of control modules 3. The main control board 1 is provided with a power supply circuit 11; the display screen 21 of each outbound box 2 is independently connected to the power supply circuit 11 through a power supply circuit 12, that is, the power supply circuits 12 of the display screens 21 of a plurality of outbound boxes 2 are connected in parallel; the power supply circuit 12 of each display screen 21 is provided with a control component 3, and the control component 3 is used for cutting off and conducting each power supply circuit 12. When the control component 3 cuts off the power supply loop 12, the display screen 21 of the outbound box 2 cannot be connected with the power supply and is in a dormant state; when the control component 3 switches on the power supply loop 12, the display screen 21 of the outbound box 2 is powered on and is in a bright state.

In a specific application, the triggering time of the switching-off and switching-on actions of the control component 3 can be set according to actual requirements. However, it goes without saying that the control unit 3 renders the supply circuit 12 conductive, at least when there is a user who wishes to use the elevator, so as to allow the user to obtain information about the operation of the car 8 at that time.

In this embodiment, each control component 3 operates independently, so that when the display screen 21 of the outbound box 2 on one floor is turned on by the conduction of the control component 3 and the power supply loop 12, the display screens 21 of the other outbound boxes 2 can still be in a dormant state.

According to the elevator control system 100 provided by the embodiment of the application, each display screen 21 of the outer calling box 2 is connected to the power supply circuit 11 on the main control panel 1 through the independent control component 3 and the power supply loop 12, the plurality of display screens 21 can be independently kept to be opened and closed under the control of the control component 3 according to needs, the opening and closing of one display screen 21 cannot influence the opening and closing of the display screen 21 of the outer calling box 2 on other floors, therefore, the situation that no person uses an elevator on the current floor but the display screen 21 in the floor is lighted up is avoided, and the problem of resource waste caused by the fact that the display screen 21 is lighted up when the elevator is not used is avoided.

As mentioned above, the hall call box 2 needs to be lit up at least when the user wants to use the elevator. Therefore, in the first embodiment of the application, as shown in fig. 3, the control unit 3 comprises a first control switch 31, which is provided outside the landing door 7 of the elevator and is used to detect whether someone is around the landing door 7, i.e. whether someone needs to use the elevator. That is, the first control switch 31 is a human body induction switch. When the first control switch 31 detects that a person is near the landing door 7, it controls the power supply circuit 12 to be turned on, so that the display screen 21 on the corresponding outbound box 2 is lit.

Referring to fig. 3, the first control switch 31 may be disposed on the wall above the landing door 7, and has a generally divergent detection range (the range defined by the two dotted lines in fig. 3), and the outbound box 2 is also located within the detection range of the first control switch 31. When a person comes within the detection range, the first control switch 31 can detect the presence of the person, i.e., the user needs to use the elevator. Alternatively, the first control switch 31 may be provided on a wall above the outbound box 2.

In practical application, according to the difference between the user demand and the floor space in the building, the first control switch 31 may be disposed at other positions, so as to ensure that the user is detected and false triggering is avoided.

Specifically, the first control switch 31 may be an infrared type human body sensing switch. The infrared human body inductive switch may include an infrared detector and a control circuit (not shown) which are connected to each other, wherein the infrared detector is configured to detect infrared rays emitted from a human body, the infrared detector detects a change in infrared heat energy caused by the human body, converts a change amount of the infrared heat energy into a voltage amount, inputs the voltage amount into the control circuit, and the control circuit outputs a zero-crossing pulse to trigger a triac connected in series to the power supply circuit 12 to be turned on, so that the power supply circuit 12 may be turned on.

The above is merely an example, and in other alternative embodiments, the infrared type human body induction switch may be another type of induction switch as long as a human body can be detected. For example, an infrared type human body sensing switch may be replaced with a microwave sensing switch which controls the power supply circuit 12 to be turned off and on by detecting the movement of an object (human body) within a certain range. Details are not repeated.

The elevator comprises an existing elevator of the building and an additional elevator. For a legacy type elevator, a user may pass through the space in front of the landing door 7 without using the elevator, and thus, this situation can be avoided by adjusting the detection range of the first control switch 31. For example, the setting angle of the first control switch 31 may be adjusted so that the edge of its detection range is kept as much as possible in the vertical direction at a distance outside the landing door 7 rather than in the obliquely diverging direction.

For the additional elevator, there may be a case of entering a user on a flat floor, as shown in fig. 4, that is, the landing door 7 of the elevator is connected to the door of the user's room, hall, etc. on each floor through a corridor. The corridor is a space provided outside the existing structure of the building to communicate between the floor and the landing door 7. Usually, the user will only enter the corridor when using the elevator. In this type of elevator, the detection of a human body by the first control switch 31 is used to control the on/off of the display screen 21 of the outbound box 2 with high accuracy, and the probability of false triggering of the control assembly 3 is low.

In this first embodiment, the display screen 21 of the outbound box 2 is controlled to light up or sleep only in response to a signal whether someone is present in front of the landing door 7, whether it be daytime or nighttime.

The power supply, on/off of the indicator lamps around the call button 22 and the control unit 3 are independent, and are automatically turned off only after the car 8 arrives at the corresponding floor, and the next call signal is allowed to be input after the opening of the car door 81, the opening of the landing door 7, the closing of the landing door 7, and the closing of the car door 81 are completed. The purpose of this is that when the user presses the call button 22, if the user leaves temporarily for some reason and does not meet the triggering conditions of the control element 3, the display screen 21 can be temporarily put into a dormant state, and the call button 22 can be kept in a light state all the time, so that the user can know after returning that the car 8 has not yet reached the current floor or the car 8 has passed the current floor.

Next, a second embodiment of the present application will be described.

In this second embodiment, the control unit 3 includes a second control switch 32, which is an illuminance control switch, for detecting illuminance information in the vicinity of the outbound box 2. When the illuminance value near the outbound box 2 is greater than a preset value, the second control switch 32 turns on the power supply circuit 12, otherwise, turns off the power supply circuit 12.

In this embodiment, the reason why the display screen 21 of the outbound box 2 is controlled by separately setting an illumination control switch is that, in the existing elevator, the position of the outbound box 2 is usually in light communication with the external space, the use frequency of the elevator is higher when the illumination is higher, such as in the daytime, the illumination control switch receives the ambient illumination information, so that the display screen 21 is always kept in a lighted state, which can avoid the control component 3 from multiple actions in the daytime, thereby improving the overall service life of the control component 3, and at night, although the ambient illumination is low, the lighting device 9 is usually set near the landing door 7 of the elevator in the existing building, no matter the lighting device 9 is in automatic control (voice control or human body induction control), manual control by the user, or unified control by the elevator pipe, when the lighting device 9 is lighted, it generally indicates that someone nearby at this time comes and uses the elevator or the elevator is still used by the user at this time, thus, it can be indirectly indicated that someone is using the elevator at this time.

Under the condition that the elevator is additionally installed to enter the house, the user usually can manually turn on or automatically trigger the lighting device 9 in the corridor to light up only when entering the corridor, so that the display screen 21 of the outbound box 2 is controlled to light up or light down through the illumination control switch, and the elevator has relatively high accuracy and low false triggering rate.

In the case of the above-mentioned flat entrance with a ladder, the height of the window in the living room or the living room is generally about 1.2 m, and is generally close to the installation height of the display screen 21 of the outbound box 2. Therefore, in this embodiment, at night and with the lighting device 9 in the corridor turned off, the display screen 21 also enters the sleep state, and at this time, no light source in the corridor projects to the windows of the living room or the living room, so that the work and rest of the user are not affected, and the user experience is improved.

In this embodiment, the illuminance control switch may be disposed in the vicinity of the lighting device 9, for example, on the wall ceiling (ceiling) of a corridor or corridor together with the lighting device 9, which directly detects the illuminance of the lighting device 9; or, since the illumination range of the illumination device 9 is usually large, the illumination control switch may also be disposed at a position far away from the illumination device 9, for example, the illumination control switch may be disposed near the outbound box 2, such as on a sidewall of a wall where the outbound box 2 is located, for indicating an illumination value of the surface of the outbound box 2, specifically, a wall above the outbound box 2 or above the landing door 7; even more, the illumination control switch may be integrated on the outbound box 2. In practical applications, the position of the illuminance control switch is set as long as the illuminance control switch can ensure that the light from the lighting device 9 is received.

Specifically, the illuminance control switch includes an illuminance sensor and a control circuit (not shown) connected to each other. The illuminance sensor is used for receiving the irradiation of visible light in the environment, converting an optical signal into an electric signal and outputting the electric signal to the control circuit. When the visible light in the environment is greater than a preset value, the visible light can output an electric signal to the control circuit, then the control circuit can be conducted, and the power supply loop 12 can be conducted; when the visible light in the environment is less than or equal to the preset value, no electric signal is output, and therefore the control circuit is kept disconnected.

The preset value and the corresponding division of the time periods in the day and at night are not unique, and can be set according to factors such as user requirements, seasons, building environments and the like. For example, the preset value may be 3LUX, or may be other values, which is not described in detail herein.

Next, a third embodiment of the present application will be described.

In the third embodiment, the display screen 21 of the outbound box 2 is kept normally on during the day time period, and is controlled to light up or sleep during the night time period according to the signal of whether a person is present in front of the landing door 7.

As shown in fig. 7 and 8, the control assembly 3 includes a first control switch 31 'and a second control switch 32' connected in parallel to the power supply circuit 12, the first control switch 31 'being used for detecting whether a person is present, and the second control switch 32' being used for turning on or off at different times of the day. In this way, the control unit 3 can control the display screen 21 of the outbound box 2 to light up during one or more specific periods of the day (e.g., daytime) and/or with a person and to sleep during another period or periods, e.g., at night, without a person.

Similarly, in this embodiment, since the elevator is used more frequently in the daytime, the second control switch 32' of the control module 3 can be prevented from being operated many times in the daytime, so that the overall service life of the control module 3 can be prolonged, the influence of frequent turning on and off of the display screen 21 on the performance thereof can be prevented, and the accuracy of detection on whether someone is using the elevator can be improved.

The first control switch 31' may refer to the type and setting manner of the infrared human body sensor switch/microwave sensor switch in the first embodiment, and will not be described herein again.

Wherein, optionally, the second control switch 32' is an illumination control switch for detecting the ambient illumination, and determining whether the current time is the day time or the night time according to the ambient illumination information. The second control switch 32 switches on the power supply circuit 12 when the ambient illuminance value is greater than a preset value (which is independent of the preset value in the second embodiment), and switches off the power supply circuit 12 otherwise. The selection of the preset value in the embodiment, that is, the division of the time periods in the day and at night, can be set according to factors such as user requirements, seasons, building environments and the like. For example, the predetermined value may be 2.5LUX, or 3LUX, or other values.

The second control switch 32' is preferably positioned to receive ambient light more accurately and to divide the day and night. For example, if the floor of the building is heavily shielded and the light in the corridor is not sufficient even in the daytime, the second control switch 32' may be disposed at a position close to the window of the corridor to be able to accurately detect the ambient illuminance; if the space outside the building floor is wide and the light in the corridor is sufficient during daytime, the second control switch 32' can be arranged at any suitable position of the wall in the corridor, such as above the landing door 7 or above the outbound box 2.

In this way, in the present embodiment, during the day, the second control switch 32' is kept normally turned on, so that the power supply loop 12 is kept turned on. At night, the second control switch 32 ' is kept off, and when the first control switch 31 ' detects that a person arrives near the landing door 7, the first control switch 31 ' enables the power supply loop 12 to be conducted, and the display screen 21 of the outbound box 2 is lighted.

In this embodiment, the display screen 21 is normally lit during the day, and is lit only when someone arrives near the landing door 7 at night, and enters a sleep state at other times at night. Especially for the condition that the elevator is additionally arranged and the elevator enters the house, the influence of the constant brightness of the display screen 21 on the user at night is greatly reduced, and the use experience of the user is improved. Moreover, compare in aforementioned second embodiment, at night and the vestibule in lighting device 9 not for the induction control's basis, even the user does not have manual lighting device 9 of opening and directly has got into the vestibule, control assembly 3 also can make the display screen 21 of exhaling box 2 outward light through the response to the human body to, further improved the detection to the human body, improved the rate of accuracy, made things convenient for user's use.

Alternatively, in an alternative embodiment, the second control switch 32' is replaced by a time control switch that can be turned off and on for a specific period of time without an external trigger signal. The time periods of disconnection and conduction (day period and night period) are set with reference to factors such as the user's work and rest time, season, building environment, and the like.

For example, the time control switch may be set to remain on between six am and six pm and off between six pm and the next morning. Or may be a set time period divided by other time nodes, which is not described in detail again for example.

Finally, a fourth embodiment of the present application is introduced.

The fourth embodiment is to replace the first control switch 31 ' in the third embodiment with another illuminance control switch, the second control switch 32 ' is an illuminance control switch, and the first control switch 31 ' is disposed near the lighting device 9 and is used for directly detecting the illuminance of the lighting device 9 to reflect the illuminance on the surface of the hall call box 2. In addition, the setting and the application of the illuminance control switch can refer to the description of the second control switch 32 in the second embodiment, and details are not repeated.

Alternatively, the second control switch 32 'in the third embodiment is replaced with a time control switch for turning on and off the power supply circuit 12 during the day and night, respectively, and the first control switch 31' is still an illuminance control switch for being disposed in the vicinity of the lighting device 9 for directly detecting the illuminance of the lighting device 9 to reflect the illuminance on the surface of the outbound box 2.

Another object of the embodiments of the present application is to provide an elevator, which includes the elevator control system 100 as described in the above embodiments.

The elevator that this application implementation provided, the box 2 is exhaled outward of its each floor can independently keep opening and closing under control of control assembly 3 according to the user's needs, has avoided exhaling outward the problem that box 2 caused the wasting of resources when not using.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
