Referring to fig. 1, fig. 1 is a flowchart illustrating steps of an elevator night guard method according to the present invention. A night guard method for an elevator, comprising the steps of:
s1, when an external call instruction is received, obtaining an external call floor corresponding to the external call instruction;
S2, judging whether the current time is within a preset precaution time range or not, and judging whether the calling floor is a preset precaution floor or not;
S3, if yes, the elevator is allocated to respond to the call-out instruction to reach the call-out floor;
s4, receiving a button instruction of a current passenger through an inner call button in the elevator, and acquiring a destination floor corresponding to the button instruction;
S5, judging whether the destination floor is a non-precautionary floor or not;
S6, if so, switching the elevator into a night precaution mode, and under the night precaution mode, only responding to a button instruction of an inner calling button in the elevator and canceling the display of an outer calling display panel of the elevator;
s7, after the elevator responds to the button instruction and reaches the destination floor, judging whether the current passenger leaves the elevator;
And S8, if so, switching the elevator into a normal mode after the elevator is operated to a random floor.
In the step S1, the call command is a command generated when the passenger calls the elevator through the call button of the floor, that is, the passenger presses the call button to generate the call command and send the call command to the elevator control system. When the control system receives the call-out instruction, the floor where the passenger sends out the call-out instruction is obtained and is taken as the call-out floor.
In the above step S2, the prevention time range may be set according to the requirement, and in this embodiment, the prevention time is set from 22 points on the day to 6 points on the next day. While the arrangement of the guard floors is such that passengers are generally taking the elevator as a floor, such as a lobby floor and an underground parking floor. When the control system receives the call-out instruction, the current time can be acquired, then whether the current time is in a preset precaution time range or not is judged, and whether the call-out floor is a preset precaution floor or not is judged, so that whether the elevator meets the condition of switching to a night precaution mode or not is judged.
In the step S3, if the current time is in the preset precaution time range and the call-out floor is at the preset precaution floor, that is, the current time is between the current 22 points and the next 6 points, the call-out floor is a hall floor or an underground parking floor, then a part of elevator mode switching conditions are satisfied, an elevator is allocated to the passenger, and the allocated elevator responds to the call-out instruction to reach the call-out floor. If not, the elevator operates normally.
In the step S4, the button instruction is an instruction generated when the passenger selects a floor or issues control through an elevator car call button, that is, the passenger presses a certain call button, and a button instruction can be generated and sent to the elevator control system. When the control system receives the button instruction, the floor corresponding to the button pressed by the passenger on the call button can be obtained and used as the destination floor.
Further, before the step of receiving a button instruction of the current elevator passenger through an in-call button in the elevator at step S4, the method further comprises:
S3a, detecting whether a light curtain of the elevator acts or not;
And S3b, if so, executing the step of receiving the button instruction of the current elevator passenger through an internal call button in the elevator.
In the above-mentioned steps S3a and S3b, the light curtain is a protective device of the elevator, typically provided at the elevator car door. The light curtain may be a photosensor or other structure. When the light path of the light curtain is blocked, the light curtain can feed back a signal, and the light curtain feedback signal indicates the light curtain action. Therefore, passengers can shield the light curtain in the process of entering the elevator, and whether passengers enter the elevator can be judged by detecting whether the light curtain of the elevator acts or not, so that the passengers can enter the elevator car. Then, a step of receiving a button instruction of the current elevator passenger through an in-call button in the elevator is performed to acquire a target floor desired by the passenger.
In the above steps S5 and S6, it is determined whether the destination floor to which the passenger wants is a non-precautionary floor, and it is also determined whether the destination floor to which the passenger wants is a floor other than the hall floor and the underground parking garage floor, so that it is determined whether the passenger is home, and if the destination floor to which the passenger wants is a floor other than the hall floor and the underground parking garage floor, it is explained that the passenger is home, and therefore the elevator is switched to the night precautionary mode. Under the night guard mode, the elevator only responds to the button instruction of the inner calling button in the elevator and does not respond to the button instruction of the outer calling button any more, so that the elevator enters a straight driving state, reaches a target floor, cannot be called out and stopped by other floors in the middle, and provides safety guarantee for females, minors or weak people when the elevator is taken by a single person at night. Meanwhile, the display of the calling display boards of all floors is canceled, the calling display boards of all floors do not display the floor and the direction of the elevator, and trailing persons are prevented from knowing the information of the home floor of the passenger according to the calling display boards, so that the night trailing is prevented, and the safety of the passenger is protected.
In the above step S7, after the elevator reaches the destination floor, it is also possible to determine whether the current passenger leaves the elevator by detecting whether the light curtain is operated, and if the light curtain is operated, it is indicated that the passenger has left the elevator.
In the above step S8, after the passenger leaves the elevator, the elevator is operated to a random floor, and the elevator is switched to a normal mode, in which the elevator resumes the display of the outer call display panel in response to the button instructions of the outer call button and the inner call button. Because the elevator is at random floor, when the display panel is recalled, the trailing personnel can not know the floor information of the passenger at home according to the display panel, thereby protecting the safety of the passenger.
Further, in the night guard time range, the passengers are seldom, generally, single passengers take the elevator, but the situation of taking the elevator by more than two passengers is not excluded, so after the step of receiving the button instruction of the current elevator passenger through the inner call button in the elevator in the step S4, the method further comprises:
S4a, acquiring a first video picture in the elevator through a first image acquisition mechanism arranged in the elevator, and determining the number of passengers in the elevator according to the acquired first video picture;
S4b, judging whether the number of passengers in the elevator is greater than one;
And S4c, if yes, stopping the elevator operation, and carrying out audio-visual reminding in the calling floor and the elevator.
In the above steps S4a to S4c, the first image capturing mechanism may include a plurality of cameras, so that the first video image in the elevator is captured by the cameras, the number of passengers in the elevator may be determined based on the first video image, if the number of passengers in the elevator is greater than one, the operation of the elevator is stopped, and an audiovisual prompt (such as voice and image prompt) is performed, so that the passengers are raised to avoid being followed, and the passengers with the following passengers may be worried about being able to leave the elevator by themselves.
Further, when a plurality of people wait for the elevator on the precaution floor, in order to avoid the situation that the queue is inserted or the elevator is not occupied, the waiting time of the weak groups such as females and underadults is too long, and in step S3, the step of allocating the elevator to reach the summons floor in response to the summons command comprises:
S31, acquiring a second video picture of the recall floor through a second image acquisition mechanism arranged on the recall floor, and determining the number of passengers on the recall floor according to the acquired second video picture;
s32, distributing elevators allowed to be used by passengers according to the number of passengers, and enabling the distributed elevators to respond to the recall instruction to reach the recall floor.
In the steps S31 and S32, the second image acquisition mechanism includes a plurality of cameras, so that a second video image of the calling floor is acquired through the cameras, the number of passengers on the calling floor can be determined based on the second video image, then, the elevators allowed to be used by the passengers are allocated to each passenger according to the number of passengers, and the allocation rule can allocate the elevators according to the sequence of reaching the calling floor, so that each passenger corresponds to one elevator, and the situation of queue insertion or elevator occupation is avoided. Further, in the case where a plurality of elevators are present, in order to facilitate the passenger's knowledge of which elevator to take, passenger information (e.g., a face picture) and the elevator number of the elevator allocated to the passenger are displayed through an outside-elevator interactive screen.
Further, after the step of the assigned elevator reaching the recall floor in response to the recall instruction at step S3, the method further includes:
S3c, acquiring a first video picture in the elevator through a first image acquisition mechanism arranged in the elevator, and determining passenger information in the elevator according to the acquired first video picture;
S3d, judging whether passenger information in the elevator is consistent with passenger information displayed by the interactive screen;
And S3e, if not, stopping the operation of the elevator, and carrying out audio-visual reminding in the calling floor and the elevator.
In the steps S3c to S3e, the first image acquisition mechanism includes a plurality of cameras, so that a first video image in the elevator is acquired through the first image acquisition mechanism, passenger information (for example, a face picture) in the elevator is determined based on the acquired first video image, and then passenger information in the elevator is compared with passenger information displayed by an interactive screen, so that passengers can be ensured to enter the correct elevator, the elevator can be operated, the situation of queue insertion is avoided, and the rights and interests of the passengers are ensured.
