Description
Technical Field
The invention relates to the technical field of elevator control, in particular to an intelligent elevator stopping method and system.
Background
The elevator brings great convenience to life, and is time-saving and labor-saving. However, the existing elevators still have disadvantages in operation. We should all encounter the situation that when you take the elevator and do not reach the target floor, the elevator stops at the middle floor, but after the elevator door is opened, the door does not have people to wait for the elevator, and then the elevator door is closed to continue running. This is probably because the person who made the call operation leaves the elevator after calling the call, and sometimes has something to do, such as forgetting to take something, and the like, so that the riding efficiency of the passengers in the elevator is unnecessarily affected, and the passenger carrying efficiency of the elevator is also affected.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides an intelligent elevator stopping method and system, which can effectively reduce unnecessary stopping in the running process of an elevator, thereby improving the passenger carrying efficiency of the elevator.
The purpose of the invention is realized by the following technical scheme:
an intelligent stopping method for an elevator comprises the following steps: after a call request outside the elevator is received, calculating the time required by the elevator to reach a call floor in real time; when the required time is less than a set value, monitoring whether a person waiting for the elevator is near a landing door of the calling floor, if so, enabling the elevator to normally stop at the calling floor; and if not, canceling the instruction of the elevator stopping at the calling floor.
According to the invention, before the elevator reaches the calling floor, whether people are at the landing doorway of the calling floor is monitored to judge whether the elevator needs to stop at the calling floor, so that the situation that the elevator stops but no people are at the doorway is greatly reduced. The set value of the time period may be set to about 3 seconds in general, and may be adjusted according to the place of use. Because the set value is smaller, when the time required by the elevator to reach the calling floor is calculated, the time of people entering and exiting the elevator when the elevator stops at the middle floor can be ignored, and only the time of opening and closing the door of the elevator and the time of ascending and descending the elevator need to be considered, so that the time calculation is simpler. In addition, a gravity sensor, an infrared correlation device and the like can be adopted as a method for monitoring whether people exist at a landing doorway of a calling floor.
Preferably, in the present invention, when a plurality of call requests are received, the time required for the elevator to reach the call floor that arrives first is calculated first; and after the elevator stops at the calling floor which arrives firstly and is closed, or after the instruction that the elevator stops at the calling floor which arrives firstly is cancelled, calculating the time required by the elevator to reach the next floor which arrives in real time. Because the elevator necessarily stops according to the high-low sequence of the floors, the calculation is carried out layer by layer, so that the disorder of data is avoided, and the accuracy of judgment is ensured.
Preferably, after receiving a call request outside the elevator, the method determines whether the selected floor outside the elevator and the selected floor inside the elevator have the same floor, and if so, cancels the calculation of the time required by the elevator to reach the floor; and if not, calculating the time required by the elevator to reach the external call floor in real time. Of course, if someone needs to arrive at a certain floor inside the elevator, after the elevator calls someone outside the floor, it is not necessary to judge whether the outside person walks away, and the elevator necessarily needs to stop at the floor.
Preferably, the method for calculating the time required for the elevator to reach the call floor specifically comprises the following steps: according to the condition of selecting floors in the elevator, only the time for opening and closing the door of the elevator and the time for ascending and descending the elevator are calculated. Specifically, according to the situation that floors are selected in the elevator before the floor is called by an outside call, the times of opening and closing the door of the elevator are calculated, so that the time required for opening and closing the door (the door opening action and the door closing action of the elevator are constant) is calculated, meanwhile, the time required for ascending or descending of the elevator between adjacent stop floors is calculated (the operation parameters of the elevator are constant, and the time for accelerating, decelerating and running at a constant speed can be accurately calculated), and a plurality of ascending or descending time periods are accumulated.
Preferably, the method for monitoring whether people exist near the landing door of the calling floor comprises the following steps: monitoring is carried out through a plurality of gravity sensors arranged below the floor, and the lowest monitoring value is set, and the gravity sensors are uniformly distributed near the landing door. Monitoring can not receive the restriction of wall body through gravity sensor to enlarge the scope of monitoring, of course, in order to avoid the interference, we can set up minimum monitoring value, and gravity is less than this value and then ignores promptly, can place the garbage bin often like layer door, also can avoid child to take the elevator alone simultaneously.
Preferably, when the required time is less than a set value, the change trend of the gravity signal is sequentially monitored by a plurality of gravity sensors, whether the elevator waiting personnel are in a moving state far away from a landing door is judged, and if yes, an instruction of stopping the elevator at the elevator calling floor is cancelled; if not, the elevator is enabled to stop at the calling floor normally. When the required time is less than the set value, the elevator is about to arrive at the floor, and the elevator waiting personnel at the floor can see the running condition of the elevator through the display screen above the landing door, so if the elevator is about to arrive at the time and the elevator waiting personnel are far away from the landing door, the elevator is considered to have something to go away, and the elevator does not need to stop at the floor. Certainly, the "the plurality of gravity sensors monitor the change trend of the gravity signals in sequence" means that different gravity sensors monitor the gravity signals in sequence, and the gravity signals disappear in sequence, if there are a plurality of people waiting for the elevator, and some people are still waiting, the gravity signals monitored by the gravity sensors at the waiting people do not disappear, and the situation that the elevator stop is cancelled does not exist.
The invention also provides an elevator intelligent stop system, which comprises:
the receiving module is used for receiving a floor selection request inside the elevator and a call request outside the elevator;
the computing module is used for computing the time required by the elevator to reach an external calling floor in real time;
the monitoring module is used for monitoring whether elevator waiting personnel exist near a landing door of an external elevator calling floor;
and the control module is used for controlling the monitoring module to monitor when the time calculated by the calculation module is less than a set value, and controlling whether the elevator normally stops at the calling floor or not according to the monitoring result of the monitoring module.
Preferably, the control module includes:
the time judging unit is used for judging whether the value of the calculating module is smaller than a set value or not;
the elevator calling judging unit is used for judging whether the calling floor outside the elevator and the selected floor inside the elevator have the same floor;
the elevator control unit cancels the work of the calculation module if the result of the calling call judgment unit is positive, so that the elevator stops at the calling floor; if not, the computing module is started, and the elevator is controlled to stop at the calling floor according to the result of the time judging unit.
Preferably, the monitoring module comprises a plurality of uniformly distributed gravity sensors, and the control module further comprises:
and the movement judgment unit is used for judging whether the elevator waiting personnel are in a movement state far away from the landing door according to the change trend of the gravity signals monitored by the gravity sensors in sequence.
Preferably, the calculation method of the calculation module comprises: and only calculating the door opening and closing actions of the elevator and the time for the elevator to go up and down according to the floor selection condition in the elevator of the receiving module.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
An intelligent stopping method for an elevator comprises the following steps: after a call request outside the elevator is received, calculating the time required by the elevator to reach a call floor in real time; when the required time is less than a set value, monitoring whether a person waiting for the elevator is near a landing door of the calling floor, if so, enabling the elevator to normally stop at the calling floor; and if not, canceling the instruction of the elevator stopping at the calling floor.
According to the invention, before the elevator reaches the calling floor, whether people are at the landing doorway of the calling floor is monitored to judge whether the elevator needs to stop at the calling floor, so that the situation that the elevator stops but no people are at the doorway is greatly reduced. The set value of the time period may be set to about 3 seconds in general, and may be adjusted according to the place of use. Because the set value is smaller, when the time required by the elevator to reach the calling floor is calculated, the time of people entering and exiting the elevator when the elevator stops at the middle floor can be ignored, and only the time of opening and closing the door of the elevator and the time of ascending and descending the elevator need to be considered, so that the time calculation is simpler. In addition, a gravity sensor, an infrared correlation device and the like can be adopted as a method for monitoring whether people exist at a landing doorway of a calling floor.
Specifically, when a plurality of call requests are received, the time required by the elevator to reach the call floor which arrives at the first is calculated; and after the elevator stops at the calling floor which arrives firstly and is closed, or after the instruction that the elevator stops at the calling floor which arrives firstly is cancelled, calculating the time required by the elevator to reach the next floor which arrives in real time. Because the elevator necessarily stops according to the high-low sequence of the floors, the calculation is carried out layer by layer, so that the disorder of data is avoided, and the accuracy of judgment is ensured.
In addition, after receiving a call request outside the elevator, judging whether the call floor outside the elevator has the same floor with the selected floor inside the elevator, and if so, cancelling the calculation of the time required by the elevator to reach the floor; and if not, calculating the time required by the elevator to reach the external call floor in real time. Of course, if someone needs to arrive at a certain floor inside the elevator, after the elevator calls someone outside the floor, it is not necessary to judge whether the outside person walks away, and the elevator necessarily needs to stop at the floor.
The method for calculating the time required by the elevator to reach the calling floor specifically comprises the following steps: according to the condition of selecting floors in the elevator, only the time for opening and closing the door of the elevator and the time for ascending and descending the elevator are calculated. Specifically, according to the situation that floors are selected in the elevator before the floor is called by an outside call, the times of opening and closing the door of the elevator are calculated, so that the time required for opening and closing the door (the door opening action and the door closing action of the elevator are constant) is calculated, meanwhile, the time required for ascending or descending of the elevator between adjacent stop floors is calculated (the operation parameters of the elevator are constant, and the time for accelerating, decelerating and running at a constant speed can be accurately calculated), and a plurality of ascending or descending time periods are accumulated.
Further, when a call request outside the elevator is received, whether a floor needing to stop exists between a call floor outside the elevator and the current position of the elevator is judged (a floor selected in the elevator is generated), if yes, when the elevator normally runs to a floor without needing to stop between the call floor outside the elevator, the time required by the elevator to reach the call floor outside the elevator is calculated, specifically, the time required by the elevator to stop at the previous station before reaching the call floor outside the elevator is calculated when the elevator is opened, because even if two floors are adjacent layers, the time for opening and closing the door and running the elevator is not less than a set value and is enough to monitor and judge; if not, the time required for the elevator to reach the call floor outside the elevator is directly calculated.
The method for monitoring whether people exist near the landing door of the calling floor specifically comprises the following steps: monitoring is carried out through a plurality of gravity sensors arranged below the floor, and the lowest monitoring value is set, and the gravity sensors are uniformly distributed near the landing door. Monitoring can not receive the restriction of wall body through gravity sensor to enlarge the scope of monitoring, of course, in order to avoid the interference, we can set up minimum monitoring value, and gravity is less than this value and then ignores promptly, can place the garbage bin often like layer door, also can avoid child to take the elevator alone simultaneously. When the required time is less than a set value, sequentially monitoring the change trend of the gravity signals according to a plurality of gravity sensors, judging whether the elevator waiting personnel is in a moving state far away from a landing door, and if so, cancelling the instruction of stopping the elevator at the elevator calling floor; if not, the elevator is enabled to stop at the calling floor normally. When the required time is less than the set value, the elevator is about to arrive at the floor, and the elevator waiting personnel at the floor can see the running condition of the elevator through the display screen above the landing door, so if the elevator is about to arrive at the time and the elevator waiting personnel are far away from the landing door, the elevator is considered to have something to go away, and the elevator does not need to stop at the floor. Certainly, the "the plurality of gravity sensors monitor the change trend of the gravity signals in sequence" means that different gravity sensors monitor the gravity signals in sequence, and the gravity signals disappear in sequence, if there are a plurality of people waiting for the elevator, and some people are still waiting, the gravity signals monitored by the gravity sensors at the waiting people do not disappear, and the situation that the elevator stop is cancelled does not exist.
In addition, the invention also provides an intelligent elevator stopping system, which comprises:
the receiving module is used for receiving a floor selection request inside the elevator and a call request outside the elevator;
the computing module is used for computing the time required by the elevator to reach an external calling floor in real time;
the monitoring module is used for monitoring whether elevator waiting personnel exist near a landing door of an external elevator calling floor;
and the control module is used for controlling the monitoring module to monitor when the time calculated by the calculation module is less than a set value, and controlling whether the elevator normally stops at the calling floor or not according to the monitoring result of the monitoring module.
