Specifically, the elevator management device 101 may first obtain the floor button pressed by each passenger in the current elevator; the camera 102 may acquire images of passengers in the elevator, analyze the images to obtain the number of passengers included in the images as the number of passengers of all passengers in the elevator, and send the number of passengers to the elevator management device 101; after the elevator management device 101 receives the number of passengers, the number of buttons of the floor buttons pressed currently in the elevator can be determined, whether the current number of passengers is smaller than the number of buttons is judged, if the number of passengers is smaller than the number of buttons, it is indicated that more passengers press the floor buttons, so that target passengers who press more floor buttons can be determined, at least one floor button pressed by the target passengers can be cancelled, a button cancellation instruction can be sent to the elevator 103, the elevator 101 is instructed to cancel the corresponding floor button, and the number of the more pressed floor buttons is reduced. Therefore, when the elevator runs according to each pressed floor key, the probability that the elevator runs between floors corresponding to the floor keys which are pressed more can be reduced. Therefore, the scheme provided by the embodiment can reduce the resource consumption during the operation of the elevator.

In one embodiment of the application, each floor button pressed by each passenger pressing the floor button at present can be recorded in the elevator management device, and then the elevator is controlled to operate between floors corresponding to each floor button according to the record, so that each passenger is sent to a floor expected to arrive.

Correspondingly, when the floor key is cancelled, the information corresponding to the floor key can be deleted from the records, so that the elevator does not operate according to the floor corresponding to the floor key.

and the camera 102 is used for acquiring images of passengers in the elevator in the case of receiving the passenger counting instruction, obtaining the passenger number of the passengers in the current elevator based on the acquired images, and sending the obtained passenger number to the elevator management device.

Specifically, after the elevator detects that the elevator door is switched from the open state to the closed state, an elevator door closing signal can be generated and sent to the elevator management device 101, and then the elevator management device 101 controls the camera 102 to collect images and count the number of passengers.

In one embodiment of the present application, the system may further comprise a verifier,

the validator is used for judging whether the collected credential information passes validation or not under the condition that the credential information of the passenger in the elevator at present is collected, and if the collected credential information passes validation, the validation passing information representing that the passenger passes the validation is sent to the elevator 103;

the elevator 103 is used for determining the floor key pressed by the passenger under the condition of receiving the verification passing information and sending target information representing the floor key pressed by the passenger to the elevator management equipment;

and the elevator management equipment is used for receiving the target information and acquiring the floor key pressed by the passenger according to the received target information.

Wherein the credential information is used to reflect: whether the passenger has the authority to press the floor button or not, and the certificate information can comprise a human body image, a human face image, a fingerprint, a password, an elevator card and the like.

Specifically, the verifier may first collect credential information of a passenger, then verify whether the passenger has an authority to press a floor key according to the credential information, if so, generate verification passing information and send the verification passing information to the elevator 103, and after the elevator 103 determines that the passenger passes the verification, the passenger is considered to have the authority to press the floor key, so that the floor key pressed by the passenger may be obtained, and target information representing the floor key pressed by the passenger may be generated, and the target information is sent to the elevator management device 101, so that the elevator management device 101 may obtain the floor key pressed by the passenger.

Therefore, before a passenger presses a floor key, whether the passenger has the authority to press the floor key needs to be verified firstly, if so, the floor key pressed by the passenger is obtained, otherwise, the passenger is considered to have no authority to press the floor key, and the floor key pressed by the passenger is not obtained.

In an embodiment of the application, after the validator collects the credential information of the passenger, the validator may compare the credential information with a preset information base, and if the credential information consistent with the credential information of the passenger exists in the information base, it indicates that the passenger passes the validation.

For example, when the credential information is a face image, the camera may collect a face image of a passenger as an image to be verified, compare the image to be verified with a face image prestored in the information base, and consider that credential information consistent with the credential information of the passenger exists in the information base and further consider that the passenger passes verification if the similarity between the image to be verified and the face image in the information base reaches a preset similarity threshold;

or, in the case that the credential information is a fingerprint, the camera may collect the fingerprint of the passenger as a fingerprint to be verified, compare the fingerprint to be verified with a fingerprint pre-stored in the information repository, and consider that credential information consistent with the credential information of the passenger exists in the information repository when the similarity between the fingerprint to be verified and a fingerprint in the information repository reaches a preset similarity threshold, and then consider that the passenger passes verification.

In an embodiment of the present invention, the verifier may first collect credential information of a passenger to be pressed who presses a floor key, and after the credential information is verified, send verification passing information that characterizes that the passenger to be pressed passes verification to the elevator 103, and the elevator 103 may detect the floor key pressed by the passenger to be pressed, determine the detected floor key as the floor key pressed by the passenger to be pressed, and send information of the floor key pressed by the passenger to the elevator management device.

In an embodiment of the present application, the elevator 103 may use the first pressed floor key detected after receiving the verification passing message as the floor key pressed by the passenger to be pressed. It will be appreciated that passenger authentication information needs to be collected once before each floor key is determined to be pressed.

In addition, the elevator 103 may use all the detected pressed floor buttons after receiving the verification passing information of the passenger waiting to be pressed once and before receiving the next verification passing information as the floor buttons pressed by the passenger waiting to be pressed. It will be appreciated that each passenger may press multiple floor buttons after verification has passed.

In one embodiment of the application, the elevator 103 is used for sending an elevator running signal to the elevator management equipment under the condition of detecting the vertical running of the elevator;

the elevator management device 101 is used for obtaining the number of passengers obtained based on the image collected by the camera 102 after receiving the elevator operation signal, and canceling at least one pressed floor key pressed by the target passenger except the newly pressed floor key according to the floor key pressed by the passenger pressing the floor key under the condition that the number of passengers is less than the number of keys of the currently pressed floor key.

Specifically, if the elevator detects that the elevator starts to vertically run, an elevator running signal representing that the elevator is in a vertical running state can be sent to the elevator management device, and the elevator management device obtains the current running state of the elevator. In the vertical operation process of the elevator, if the elevator management device 101 detects that a passenger presses a new floor key at present, the current number of passengers in the elevator can be obtained by using a camera, the number of the floor keys pressed at present is determined, and under the condition that the number of the passengers is less than the number of the keys, at least one floor key can be selected from at least one pressed floor key, except the newly pressed floor key, pressed by a target passenger, and the selected floor key is cancelled.

The at least one floor key pressed earliest among the floor keys that have been pressed may be selected, or at least one floor key pressed by at least one passenger with the largest number of floor keys, other than the newly pressed floor key, may be selected.

In one embodiment of the application, the elevator 103 sends a passenger key signal to the elevator management device when detecting that a passenger presses a new floor key with a current key, and the elevator management device determines that the passenger presses the new floor key;

when the elevator detects that a passenger presses a new floor button, the elevator can send a passenger counting instruction to the camera, instruct the camera to collect images of the passenger in the elevator at present, count the number of the passengers based on the images, and send the number of the passengers to the elevator management equipment, so that the elevator management equipment can obtain the current number of the passengers;

in addition, after determining that the current passenger presses a new floor button, the elevator management device can send a passenger counting instruction to the camera to instruct the camera to collect the image of the passenger in the current elevator, count the number of the passengers based on the image, and send the number of the passengers to the elevator management device, so that the elevator management device can obtain the current number of the passengers.

In addition, in an embodiment of the present application, the camera 102 may also continuously acquire images in the elevator, and the camera may analyze whether a passenger presses a new floor button based on the images, and if so, may send a passenger button signal to the elevator management device, and the elevator management device determines that the passenger currently presses the new floor button;

the elevator management device can also analyze whether a passenger presses a new floor button or not based on the image.

The elevator key control method can be realized by utilizing the elevator control system, and the elevator key control method is described in detail below.

Referring to fig. 2, fig. 2 is a schematic flow chart of an elevator key control method provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps S201 to S203:

s201, determining the floor button pressed by each passenger pressing the floor button in the current elevator.

Specifically, for each passenger pressing a floor button in the elevator, the floor button pressed by the passenger can be obtained.

In one embodiment of the application, images within the elevator may be collected, each passenger pressing a floor button may be detected based on the images, and the floor button pressed by the passenger may be detected based on the images. Specifically, images in the elevator can be continuously acquired to obtain continuous images, and then the floor key pressed by each passenger pressing the floor key in the current elevator is determined based on the continuous images.

In addition, the elevator can detect the floor buttons pressed by each passenger pressing the floor buttons, and then the detection result is sent to the elevator management equipment, so that the elevator management equipment can obtain the floor buttons pressed by each passenger pressing the floor buttons in the current elevator.

In one embodiment of the application, the floor button pressed by each passenger whose verification information passes the verification in the current elevator can be obtained.

Specifically, the collected credential information of the passenger may be obtained, and then it is verified whether the passenger has the authority to press the floor key according to the credential information, if so, the floor key pressed by the passenger is obtained, and the floor key is determined to be the floor key pressed by the passenger.

In one embodiment of the present application, the pressed time when each floor key is pressed can also be obtained. Specifically, each time a pressed floor key is obtained, the time when the floor key is pressed may be determined as the time when the floor key is pressed.

In one embodiment of the application, after determining the floor key pressed by each passenger pressing the floor key in the current elevator, the key information of the floor key can be determined, and the key information is added to the key information record, so that the target passenger can be determined based on the key information record in the following process. Wherein the key information record is used for: and recording the currently pressed floor key and the passenger information of the passenger pressing the floor key, and deleting the key information of the floor key from the key information record after the elevator runs to the floor corresponding to the floor key in the key information record and opens the elevator door. The passenger information may be credential information of the passenger or a passenger identification of the passenger.

In addition, the press time when each floor key is pressed can be recorded in the key information record. Therefore, when the floor key is cancelled in the subsequent process, the floor key to be cancelled can be selected according to the pressing time of each floor key in the record.

And S202, obtaining the passenger number of the passengers in the current elevator.

In one embodiment of the application, when obtaining the number of passengers, an image in the current elevator can be obtained, and the number of passengers in the current elevator is determined based on the image;

in addition to this, the number of passengers in the elevator can be counted on the basis of passenger sensors. Specifically, above-mentioned passenger sensor can detect the passenger of business turn over elevator, detects the passenger and gets into under the circumstances in the elevator, can generate a passenger and increase the signal, detects the passenger and leaves under the circumstances of elevator, can generate a passenger and reduce the signal, through statistics above-mentioned passenger increase signal, passenger reduce the signal, realizes the statistics to passenger's quantity in the elevator.

And S203, under the condition that the number of the passengers is less than the number of the keys of the currently pressed floor key, canceling at least one floor key pressed by the target passenger according to the floor key pressed by the passenger pressing the floor key.

Wherein the target passenger is: the number of passengers pressing floor buttons in the current elevator is more than 1.

Specifically, when the number of passengers is less than the number of currently pressed buttons, it is described that there is a situation where the number of passengers has pressed more floor buttons, so that according to the floor buttons pressed by the passengers pressing the floor buttons, the passengers whose number of currently pressed floor buttons is greater than 1 can be determined as target passengers who have pressed more floor buttons, and then at least one floor button is cancelled from the floor buttons pressed by the target passengers.

In one embodiment of the application, when the number of keys of the currently pressed floor key is determined, an image of the current elevator key can be obtained, and the number of the lightened floor keys is detected based on the image and is used as the number of keys of the currently pressed floor key. Specifically, after each floor key is pressed, the floor key is usually lit up, so that the number of currently pressed floor keys can be obtained based on the number of lit-up floor keys.

In addition, the number of the floor keys which are pressed currently can be counted according to the information of the floor keys which are pressed currently and recorded in the floor key record.

In one embodiment of the present invention, when the floor key pressed by the target passenger is cancelled, the floor key pressed by the target passenger at the earliest time may be cancelled. And under the condition that the number of the floor buttons pressed by the target passenger is more than 1, wherein the probability that the floor button pressed earliest is the floor button pressed by the target passenger by mistake is higher, the floor button pressed earliest is cancelled, and the accuracy of the reserved floor button can be improved.

In addition, the floor button pressed by the target passenger last time can be cancelled, so that the target passenger can be reminded to press more floor buttons in a button cancelling mode in time, and the target passenger can change the pressed floor button in time.

In addition, at least one floor key can be randomly selected from the floor keys pressed by the target passenger, and the selected floor key is cancelled.

In one embodiment of the present application, after the target passenger is determined, all floor buttons pressed by the target passenger may also be cancelled, so that the target passenger may press the floor buttons again;

in addition, under the condition that the number of passengers is less than the number of the keys of the floor key pressed currently, the difference value between the number of the keys of the floor key pressed currently and the number of the passengers can be calculated, and the difference floor keys are eliminated from the floor keys pressed by the target passengers.

Specifically, the difference between the current number of passengers and the number of keys may be calculated, where the difference is the number of floor keys pressed by all passengers, and therefore the difference floor keys pressed by the target passenger may be cancelled. For example, assuming that the current number of passengers is 5, the floor key is 7, and the difference between the number of passengers and the number of keys is 2, the 2 floor keys pressed by the target passenger may be cancelled. Therefore, the number of the keys of the finally pressed floor keys is equal to the number of passengers, and each passenger presses one floor key on average, so that the probability that the passengers press more floor keys is reduced, the probability that the elevator operates between floors corresponding to the more pressed floor keys is reduced, and the resource consumption during the operation of the elevator is reduced.

In one embodiment of the application, when the different floor keys are cancelled, the different floor keys can be randomly selected from the floor keys pressed by the target passenger, and then the selected floor keys are cancelled;

at least one passenger to be cancelled of the floor buttons to be cancelled can also be selected from the target passengers, and at least one floor button pressed by the passenger most recently or earliest can be cancelled for each passenger to be cancelled.

The sum of the number of the buttons of the floor buttons cancelled by each passenger to be cancelled is the difference.

Specifically, one or more passengers to be cancelled may be selected from the target passengers, and then at least one latest or earliest floor key pressed by each passenger to be cancelled is cancelled, and the sum of the number of cancelled floor keys is the difference, so that the number of cancelled floor keys is consistent with the number of passengers.

In one embodiment of the application, when a passenger to be cancelled is selected, the passenger with the largest number of pressed floor buttons can be preferentially selected as the passenger to be cancelled; or the passenger who presses the floor button most recently or earliest can be selected preferentially from the target passengers;

for each passenger to be cancelled, all floor buttons pressed by the passenger can be cancelled; the latest or earliest pressed floor key of the passenger may also be retained, and other floor keys may be cancelled, which is not limited in the embodiments of the present application.

In the elevator key control scheme provided by the embodiment, the floor key pressed by each passenger pressing the floor key in the current elevator is determined; obtaining the passenger number of passengers in the current elevator; under the condition that the number of passengers is less than the number of keys of the floor key pressed currently, canceling at least one floor key pressed by a target passenger according to the floor key pressed by the passenger pressing the floor key, wherein the target passenger is as follows: the number of passengers pressing floor buttons in the current elevator is more than 1. Therefore, the floor buttons pressed by each passenger in the current elevator can be obtained firstly, then whether the number of the current passengers is smaller than the number of the floor buttons pressed currently is judged, if the number of the passengers is smaller than the number of the buttons, the passengers press more floor buttons, so that the target passengers who press more floor buttons can be determined, at least one floor button pressed by the target passengers is cancelled, and the number of the more pressed floor buttons is reduced. Therefore, when the elevator runs according to each pressed floor key, the probability that the elevator runs between floors corresponding to the floor keys which are pressed more can be reduced. Therefore, the scheme provided by the embodiment can reduce the resource consumption during the operation of the elevator.

In one embodiment of the present application, when the floor key is cancelled in S203, it may be determined whether the number of passengers is less than the number of keys of the currently pressed floor key, and if so, the passenger with the largest number of pressed floor keys is determined as a multi-key passenger according to the floor key pressed by the passenger pressing the floor key; and canceling a floor key pressed by a multi-key passenger, and returning to the step of judging whether the number of passengers is less than the number of keys of the currently pressed floor key.

Specifically, when the number of current passengers is smaller than the number of floor buttons, the number of floor buttons pressed by each passenger pressing a floor button may be determined according to the number of floor buttons pressed by the passenger pressing a floor button obtained in step S201, and then the passenger pressing the floor button with the largest number may be determined as a multi-button passenger, and then a floor button is selected and cancelled from the floor buttons pressed by the multi-button passenger;

and then returning to the step of determining the number of the keys of the floor key which is pressed currently, and judging whether the number of the current passengers is less than the number of the keys again until the number of the current passengers is not less than the number of the current keys.

When the number of the keys of the currently pressed floor key is determined, the number of the keys determined last time can be reduced by one, so that the number of the keys of the currently pressed floor key is obtained; or re-determining the number of the keys of the floor key currently pressed according to the manner of determining the number of the keys in the step S202.

In one embodiment of the application, when a floor key pressed by a multi-key passenger is cancelled, the floor key pressed by the multi-key passenger most recently or earliest can be cancelled; in addition, a floor key can be randomly selected from floor keys pressed by multi-key passengers, and the selected floor key is cancelled.

For example, assume that there are three people currently in an elevator: a, b, c and d, wherein a presses the floor key L1, b presses the floor key L2 at 11 o ' clock 2 time division and presses the floor key L3 at 11 o ' clock 3 time division, c presses the floor key L4 at 11 o ' clock 1 time division, presses the floor key L5 at 11 o ' clock 2 time division and presses the floor key L6 at 11 o ' clock 4 time division.

Counting that the current passenger number is 4, the current key number is 6, the current passenger number is less than the key number, and determining that the number of the currently pressed floor keys is third, wherein the floor key which is pressed by third most recently is L6, so that L6 can be cancelled;

then, the current number of the keys is counted again to be 5, the current number of the passengers is smaller than the number of the keys, and the maximum number of the currently pressed floor keys is determined to be B and C, wherein the newly pressed floor key is L3 in the floor keys pressed by B and C, so that L3 can be cancelled.

In an embodiment of the present application, for step S201, the floor key pressed by each passenger pressing the floor key in the current elevator may be determined in a state where the elevator door is opened. Specifically, when the elevator door is in the open state, all floor keys pressed by each passenger pressing a floor key can be obtained. Because the passenger usually frequently gets in and out of the elevator and presses down the elevator keys in the state that the elevator door is opened, all the pressed floor keys are directly obtained in the state without processing the current number of the passenger and the number of the keys, and the consumption of computing resources caused by the fact that the passenger frequently gets in and out of the elevator and presses down the elevator keys and the number of the keys is continuously changed is avoided.

Referring to fig. 3, fig. 3 is a schematic flow chart of a key determination method provided in an embodiment of the present application, where the method includes the following steps S301 to S303:

s301, acquiring the collected passenger certificate information in the state that the elevator door is opened;

s302, verifying whether the passenger has the authority to press the floor button according to the certificate information, and if so, executing S303;

and S303, determining the floor keys pressed by the passenger, and adding the key information of the floor keys to the key information record according to the time sequence.

Specifically, in the open state of the elevator door, the credential information of the passenger can be obtained first, the passenger is verified based on the credential information, and if the passenger passes the verification, the button information of the floor button pressed by the passenger can be obtained, where the button information of each floor button may include: passenger information of the passenger who presses the floor button and the pressed time of the button, wherein the passenger information can be the credential information of the passenger or the passenger identification of the passenger;

after the key information is obtained, the key information may be added to the key information record according to the time sequence, and the key information record is used for: and recording the key information of the currently pressed floor key, and deleting the key information of the floor key from the key information record after the elevator runs to the floor corresponding to the floor key in the key information record and opens the elevator door. This facilitates subsequent searching for the target passenger from the keystroke information record.

In one embodiment of the application, when counting the number of passengers of the current elevator, the number of passengers of the current elevator can be counted after the elevator door is switched from the open state to the closed state.

Specifically, after the elevator door is detected to be switched from the open state to the closed state, it is indicated that no passenger enters or exits the elevator at present, so that the number of passengers in the elevator at present can be counted, and resource consumption caused by continuous change of the number of passengers due to frequent entrance and exit of the passengers during counting of the number of passengers is avoided.

Referring to fig. 4, fig. 4 is a schematic flow chart of another elevator key control method provided in the embodiment of the present application, where the method includes the following steps S401 to S405:

s401, counting the number of passengers in the elevator at present after the elevator door is switched from the open state to the closed state;

s402, determining the number of keys of the floor key which is pressed currently;

s403, judging whether the number of the current passengers is smaller than the number of the keys, if so, executing S404;

s404, determining the passenger with the largest number of the pressed floor keys as a multi-key passenger according to the floor keys pressed by the passenger pressing the floor keys;

s405 cancels the one-floor key that was most recently pressed by the multi-key passenger, and returns to S402.

Specifically, after the elevator door is switched from an open state to a closed state, it is described that no passenger enters or exits the elevator at present, so that the current passenger number can be counted, and the current key number is determined, and under the condition that the current passenger number is smaller than the floor keys, it is described that the passenger presses more floor keys, so that the number of the floor keys pressed by each passenger pressing the floor keys can be determined, and further the passenger pressing the floor keys with the largest number is determined to be used as a multi-key passenger, and the floor keys pressed by the multi-key passenger most recently are cancelled from the floor keys pressed by the multi-key passenger;

and then returning to the step S402 to determine the number of the keys of the floor key which is pressed currently, and judging whether the current number of passengers is less than the current number of the keys again until the current number of passengers is not less than the current number of the keys, so that each passenger presses one floor key on average.

In one embodiment of the application, when counting the number of passengers of the current passenger in the elevator, the number of passengers of the current passenger in the elevator can be obtained if the passenger presses a new floor button when the elevator is vertically operated and the current button is detected to exist.

Thus, when the floor key pressed by the target passenger is cancelled, under the condition that the number of passengers is less than that of the floor key pressed currently, at least one pressed floor key, except the newly pressed floor key, pressed by the target passenger can be cancelled according to the floor key pressed by the passenger pressing the floor key.

Specifically, in the vertical operation process of the elevator, if it is detected that a passenger presses a floor key at present, the number of passengers in the elevator at present can be counted, the number of the floor keys pressed at present is determined, and under the condition that the number of the passengers is less than the number of the keys, at least one floor key can be selected from the floor keys pressed by a target passenger except the newly pressed floor key, and the selected floor key is cancelled.

Among the floor buttons that have been pressed, the floor button that was pressed the earliest may be selected, at least one floor button that is pressed by the target passenger except the newly pressed floor button may be selected, or at least one floor button that is pressed by the passenger with the largest number of floor buttons except the newly pressed floor button may be selected.

In one embodiment of the application, under the condition of vertical operation of the elevator, if the situation that a passenger presses a new floor button to be effective currently is detected, the passenger number of the passenger in the current elevator is obtained;

and under the condition that the number of the passengers is less than or equal to the number of the keys of the floor keys which are pressed except the newly pressed floor key at present, canceling at least one pressed floor key which is pressed by the target passenger except the newly pressed floor key according to the floor key pressed by the passenger pressing the floor key, and determining that the newly pressed floor key is effective.

Specifically, in the vertical operation process of the elevator, if the passenger pressing the floor key at the current time is detected, the newly pressed floor key is not in effect temporarily, but whether the number of the current passengers is less than or equal to the number of the pressed keys except the newly pressed floor key is judged, if so, the situation that more passengers press the floor key in the elevator at present is shown, if the newly pressed floor key is added, at least one pressed floor key pressed by a target passenger except the newly pressed floor key needs to be eliminated, and after the elimination, the newly pressed floor key is determined to be in effect, so that the number of the pressed keys is ensured to be not more than the number of the passengers finally.

In addition, under the condition that the elevator runs vertically, if the situation that the passenger presses the newly pressed floor key by the current key is detected, the newly pressed floor key is determined to be effective, and the number of the passengers in the current elevator is obtained;

and under the condition that the number of the passengers is less than the number of the pressed floor keys including the newly pressed floor key, canceling at least one pressed floor key which is pressed by the target passenger except the newly pressed floor key according to the floor key pressed by the passenger pressing the floor key.

Specifically, in the vertical operation process of the elevator, if the passenger presses the floor key at the current key, the passenger directly considers that the newly pressed floor key is effective, then the newly pressed floor key is judged to be added, whether the current passenger number is smaller than the number of the pressed keys is judged, if yes, the result shows that if the newly pressed floor key is added, more passengers press the floor key in the current elevator, so that at least one pressed floor key pressed by a target passenger except the newly pressed floor key needs to be eliminated, and after the floor key is cancelled, the number of the pressed keys is ensured to be not larger than the number of the passengers.

In one embodiment of the application, whether the passenger who presses the floor button before can be judged according to the floor button pressed by the passenger who presses the floor button; if yes, canceling the floor key pressed by the current key passenger before; if not, canceling at least one floor key pressed by the target passenger.

Specifically, under the condition that the number of passengers is less than the number of keys, whether the passenger who presses the current key has pressed the floor key before can be judged, if so, the floor key which is pressed before by the passenger can be cancelled, otherwise, the passenger who presses the floor key with the number greater than 1 can be searched, and at least one floor key which is pressed by the passenger can be cancelled.

Referring to fig. 5, fig. 5 is a schematic flow chart of another elevator key control method provided in the embodiment of the present application, where the method includes the following steps S501-S507:

s501, acquiring the collected credential information of the current key passenger in the vertical operation process of the elevator;

s502, verifying whether the passenger with the current key has the authority to press the floor key according to the certificate information, and if so, executing S503;

s503, counting the current passenger number, and determining the number of the keys of the floor key which is pressed currently;

s504, judging whether the number of the passengers is less than or equal to the number of the keys, if so, executing S505;

s505, judging whether the passenger presses the floor key before the current key, if so, executing S506, and if not, executing S507;

s506, canceling the floor key pressed by the current key passenger before, and determining the floor key pressed by the current key passenger currently;

s507, searching for target passengers with the number of the pressed floor keys larger than 1, canceling at least one floor key pressed by the target passengers, and determining the floor key pressed by the current key passenger currently.

Referring to fig. 6, fig. 6 is a schematic flow chart of another elevator key control method provided in the embodiment of the present application, where the method includes the following steps S601-S605:

s601, under the state that the elevator door is opened, the floor key pressed by each passenger pressing the floor key in the elevator is obtained.

S602, after the elevator door is switched from the open state to the closed state, counting the number of passengers in the elevator at present.

And S603, under the condition that the number of passengers is less than the number of the keys of the currently pressed floor key, canceling at least one floor key pressed by the target passenger according to the floor key pressed by the passenger pressing the floor key.

S604, under the condition that the elevator runs vertically, if the situation that the passenger presses a new floor button when the current button is detected, obtaining the passenger number of the passenger in the current elevator;

s605, under the condition that the number of the passengers is less than the number of the keys of the floor key pressed currently, according to the floor key pressed by the passenger pressing the floor key, at least one pressed floor key, which is pressed by the target passenger except the newly pressed floor key, is cancelled.

Therefore, when the elevator door is opened, the elevator door is considered to be in a peak time when passengers get on or off the elevator, and therefore, all floor keys pressed by all passengers pressing the floor keys can be directly determined; when the elevator door is closed, passengers do not get on or off the elevator any more, the current passenger number and the number of keys can be judged at the moment, the keys of the floors which are pressed more are cancelled, and the fact that each passenger presses the key of the floor at most on average is guaranteed; when the elevator runs vertically, if a passenger presses a floor key, the passenger presses the floor key which is pressed before, the passenger is mistakenly cancelled, or the floor to which the passenger goes is changed, or the floor key is not pressed before, so that the floor key can be reserved, other floor keys pressed by target passengers with more floor keys can be cancelled, and the accuracy of the pressed floor key is improved.
