In an embodiment, an elevator people trapping detection method is provided, referring to fig. 3, fig. 3 is a schematic flow chart of the elevator people trapping detection method in an embodiment, which is described by taking an example that the method is applied to the monitoring terminal in fig. 1, and the elevator people trapping detection method may include the following steps:
step S301, when the speed of the elevator 102 is reduced to zero and the door of the elevator 102 is in a closed state, acquiring the trigger state of a calling button in the elevator 102.
The elevator 102 may be any of various passenger elevators, cargo elevators, medical elevators, miscellaneous elevators, sightseeing elevators, vehicle elevators, ship elevators, and construction elevators. The call button in the elevator 102 may be a button disposed inside the elevator 102, and the elevator 102 may detect the triggering information of the internal button, so that a corresponding feedback action may be made according to the triggering information, for example, when a passenger presses the button on floor two in the elevator 102, the elevator 102 may go to the second floor. In this step, the monitoring terminal 104 may be trapped when detecting that the speed of the elevator 102 decreases from non-zero to zero, so that the triggering state of the call button in the elevator 102 may be obtained when the speed of the elevator 102 decreases to zero, and the monitoring terminal 104 may determine whether the elevator 102 is trapped by a person through the triggering state, for example, when the monitoring terminal 104 obtains that the call button in the elevator 102 is in the triggering state, it may be determined that the elevator 102 is trapped by a person. In the step, the triggering state of the calling button in the elevator 102 is obtained, so that whether the elevator 102 is occupied or not can be judged more accurately.
Step S302, when the triggering state of at least one elevator 102 internal calling button is acquired, the time length of the elevator 102 in a static state and the elevator 102 door in a closed state is counted.
The elevator 102 may be stationary, i.e., the elevator 102 is in a zero speed state, and normally, when the speed of the elevator 102 is reduced from non-zero to zero, at least one door opening and closing operation occurs, and if the speed of the elevator 102 is reduced from non-zero to zero, the doors of the elevator 102 are still in a closed state, people trapping may occur. In this step, the monitoring terminal 104 may acquire the trigger state of the call button in the elevator 102 when detecting that the speed of the elevator 102 decreases from non-zero to zero, and may determine that a person is in the elevator 102 if the monitoring terminal 104 acquires that the call button in the elevator 102 is in the trigger state. The monitoring terminal 104 may count the time duration that the elevator 102 is stationary and the doors of the elevator 102 are in a closed state, and determine whether a trapped state is determined to occur in the elevator 102 according to the time duration. In the step, after the triggering state of the calling button in the elevator 102 is obtained, the duration that the elevator 102 is in a static state and the door of the elevator 102 is in a closed state is counted, and whether people are trapped in the elevator 102 can be determined more accurately according to the duration.
Step S303, if the elevator 102 is static and the duration of the closed state of the door of the elevator 102 is longer than the preset duration, determining that the elevator 102 is in a trapped state.
The trapped state may be a state in which the doors of the elevator 102 cannot be opened or closed when the elevator 102 is stationary. When the elevator 102 is in motion and the elevator doors are closed, the elevator 102 is in a normal operation state, and when the elevator 102 is in rest and the elevator doors have at least one door opening action within a set time, the elevator 102 is also in a normal operation state. Therefore, the monitoring terminal 104 can count the duration that the elevator 102 is in the stationary state and the doors of the elevator 102 are in the closed state when the elevator 102 call button is in the trigger state, the monitoring terminal 104 can compare the duration that the elevator 102 is in the stationary state and the doors of the elevator 102 are in the closed state with the set duration, if the duration that the elevator 102 is in the stationary state and the doors of the elevator 102 are in the closed state is too long and is longer than the set duration, for example, three minutes, at this time, the elevator 102 is in the abnormal state, and the monitoring terminal 104 can determine that the elevator 102 is in the trapped state. In the step, the length of time that the elevator 102 is in the static state and the door of the elevator 102 is in the closed state is compared with the set length of time, so that whether the elevator 102 is in the trapped state or not can be judged more accurately.
According to the elevator trapping detection method, the triggering state of the internal calling button of the elevator 102 is obtained when the speed of the elevator 102 is reduced to zero and the door of the elevator 102 is in the closed state, the duration of the elevator 102 in the static state and the door of the elevator 102 in the closed state is counted when the triggering state of at least one internal calling button of the elevator 102 is obtained, and when the duration of the elevator 102 in the static state and the door of the elevator 102 in the closed state is longer than the preset duration, different conditions can be adopted to determine that the elevator 102 is in the trapping state according to different states of the elevator 102. Compared with the prior art, the scheme can more accurately detect whether the elevator is in the trapped state or not, and can actively take corresponding rescue measures after the trapped state is detected out, so that the safety of passengers in the elevator is more comprehensively ensured.
In one embodiment, counting the length of time that the elevator 102 is stationary and the doors of the elevator 102 are in a closed state comprises: if the elevator 102 is in the powered state, a first time period is counted from when the call button in the elevator 102 is triggered to start when the elevator 102 is stationary and the elevator doors 102 are in the closed state.
In this embodiment, the power-on state may be a state in which the 380V detection module 204 in the monitoring terminal 104 can be normally connected to the 380V power supply in the elevator 102. The monitoring terminal 104 can collect the state information of the elevator 102 in real time at this time. Thus, the monitoring terminal 104 may count the first time period that the elevator 102 is stationary and the elevator doors 102 are in a closed state since triggering the recall button in the elevator 102. In addition, the monitoring terminal 104 may count the time period from when the speed of the elevator 102 is reduced to zero when the elevator 102 is in the energized state to when the elevator 102 is stationary and the elevator doors 102 are in the closed state. The first duration may be statistical in real time. Through the embodiment, the monitoring terminal 104 can take corresponding measures to the elevator 102 according to the size of the first duration in time, so as to ensure the safety of passengers in the elevator.
In one embodiment, counting the length of time that the elevator 102 is stationary and the doors of the elevator 102 are in a closed state comprises: if the elevator 102 is in the power-off state, counting a second time length when the elevator 102 is static and the door of the elevator 102 is in the closed state from the power-off moment; the second duration is statistically obtained from elevator 102 status data buffered in the monitoring terminal 104 of the elevator 102; the second duration is less than the buffer duration of the monitoring terminal 104.
In this embodiment, the power-off state may be a state in which the 380V detection module 204 in the monitoring terminal 104 cannot be normally connected to the 380V power supply in the elevator 102. At this time, the monitoring terminal 104 cannot collect the status information of the elevator 102 in real time. The monitoring terminal 104 may buffer the state data of the elevator 102 within a set time duration in real-time detection before power failure to obtain buffered data of the elevator 102, for example, the monitoring terminal 104 may buffer the state data of the elevator 102 ten seconds ago in real-time detection. The buffer data may include the traveling speed, door zone, floor, traveling direction, door state, call-in command response state, call-in button operation state, and the like of the elevator 102. When the elevator 102 enters the power-off state, the monitoring terminal 104 may count a second time period, which is a time period from the time of the power-off state when the elevator 102 is stationary and the doors of the elevator 102 are in the closed state, from the buffer data, wherein the second time period may be counted from the buffer data, and the size of the second time period may be smaller than the time size of the buffer data.
Through the embodiment, the monitoring terminal 104 can also count the corresponding second time length from the buffer data under the condition that the elevator 102 is powered off, determine whether the elevator 102 is in the powered off and trapped state according to the second time length, and the monitoring terminal 104 can also judge whether the elevator 102 is trapped under the powered off condition, so that the monitoring terminal 104 can more comprehensively and accurately judge whether the elevator 102 is in the trapped state.
In one embodiment, determining that the elevator 102 is in a trapped state if the elevator 102 is stationary and the length of time that the doors of the elevator 102 are in the closed state is greater than a predetermined length of time includes: if the elevator 102 is in the electrified state, the elevator 102 is static, and the time length of the elevator 102 door in the closed state is longer than a first preset time length, it is determined that the elevator 102 is in the trapped state.
In this embodiment, the preset time duration may be a time duration in which the elevator 102 is stationary and the doors of the elevator 102 are in a closed state within a normal range set by the monitoring terminal 104. The first preset time period may be a time period in which the elevator 102 in the normal range is stationary with the elevator 102 in the energized state and the doors of the elevator 102 are in the closed state. The specific duration of the first preset duration may be set according to actual conditions, and may be three minutes, for example. When the elevator 102 is in the power-on state, the monitoring terminal 104 can count the time length of the elevator 102 in a stationary state and the elevator 102 door in a closed state in real time, and when the time length is greater than a set first preset time length, it can be determined that the elevator 102 is in an abnormal state, namely, a trapped state. Through the embodiment, the monitoring terminal 104 can more accurately judge whether the elevator 102 is in the trapped state or not by counting the time length of the elevator 102 in a stationary state and the elevator 102 door in a closed state in real time under the condition that the elevator 102 is electrified and comparing the counted time length with the preset time length.
Further, in an embodiment, as shown in fig. 4, fig. 4 is a flowchart illustrating a step of determining elevator trapping in an elevator trapping detection method in an embodiment, where if the elevator 102 is in the powered state, the elevator 102 is stationary, and a duration of a door of the elevator 102 in a closed state is longer than a first preset duration, determining that the elevator 102 is in the trapping state includes:
s401, if the elevator 102 is in a power-on state, the elevator 102 is static, and the time length of the closed state of the door of the elevator 102 is longer than a first preset time length, sending a door opening instruction to a door opening and closing system of the elevator 102;
s402, if the door opening and closing system of the elevator 102 receives the door opening instruction and the door of the elevator 102 is continuously in the closed state, determining that the elevator 102 is in the trapped state.
In this embodiment, the door opening and closing system may be a main control system of the elevator 102, or may be a door operator system of the elevator 102. Wherein the main control system of the elevator 102 can be a system for controlling the operation of the elevator 102 to run, stop or open/close the door, and the door motor system of the elevator 102 can be a system for controlling the elevator 102 to open/close the door. The door open command may be a command to cause the doors of the elevator 102 to perform a door opening operation. In step S401, if the elevator 102 is in the power-on state, the elevator 102 is stationary, and the duration that the doors of the elevator 102 are in the closed state is longer than a first preset duration, the elevator 102 may be determined to be in a trapped state, at this time, the monitoring terminal 104 may send a door opening instruction to the door opening and closing system of the elevator 102 to open the doors of the elevator 102, and after the door opening and closing system of the elevator 102 receives the door opening instruction, the doors of the elevator 102 are opened, and at this time, it may be determined that the trapped state of the elevator 102 is released. Otherwise, step S402 is performed, and if the door opening and closing system of the elevator 102 receives the door opening instruction, the door of the elevator 102 is not opened, and at this time, it may be determined that the elevator 102 is in a trapped state.
In this embodiment, when the elevator 102 is in the powered-on state, when the elevator 102 is stationary and the duration that the doors of the elevator 102 are in the closed state is longer than the first preset duration, the monitoring terminal 104 sends a door opening instruction to the door opening and closing system of the elevator 102, and determines whether the elevator can be normally opened according to the response of the door opening and closing system of the elevator 102 after receiving the door opening instruction, so as to more accurately determine whether the elevator 102 is in the trapped state.
In another embodiment, determining that the elevator 102 is in a trapped state if the elevator 102 is stationary and the length of time that the doors of the elevator 102 are in the closed state is greater than a predetermined length of time comprises: if the elevator 102 is in the power-off state, the elevator 102 is stationary, and the time length of the elevator 102 door in the closed state is longer than a second preset time length, it is determined that the elevator 102 is in the trapped state.
In this embodiment, the preset time duration may be a time duration in which the elevator 102 is stationary and the doors of the elevator 102 are in a closed state within a normal range set by the monitoring terminal 104. The second preset duration may be set according to a duration of the buffered data of the monitoring terminal 104, and in a general case, the second preset duration may be smaller than the duration of the buffered data of the monitoring terminal 104, and the duration of the buffered data may be set according to an actual situation, for example, may be ten seconds. The second preset time period may be a time period within the normal range of a closed state of the elevator 102 doors and the elevator 102 is stationary in the buffered data with the elevator 102 in the powered off state. The specific size of the second preset time period may be set according to actual conditions, and may be ten seconds or three seconds, for example. When the elevator 102 is in the power-off state, the monitoring terminal 104 may count the duration that the elevator 102 is stationary and the doors of the elevator 102 are in the closed state from the buffer data of the elevator 102, and when the duration is greater than a second preset duration, it may be determined that the elevator 102 is in an abnormal state, i.e., a trapped state.
Through the embodiment, the monitoring terminal 104 can count the time length of the elevator 102 in a stationary state and the elevator 102 door in a closed state from the buffer data under the condition that the elevator 102 is powered off, and can more accurately judge whether the elevator 102 is in a trapped state or not by comparing the counted time length with the preset time length.
Further, in an embodiment, as shown in fig. 5, fig. 5 is a flowchart illustrating a step of determining elevator trapping in an elevator trapping detection method in another embodiment, where if the elevator 102 is in a power-off state, the elevator 102 is stationary, and a duration that doors of the elevator 102 are in a closed state is longer than a second preset duration, determining that the elevator 102 is in a trapping state includes:
s501, if the elevator 102 is in a power-off state, the elevator 102 is static, the time length of the elevator 102 door in a closed state is longer than a second preset time length, and the time length of the elevator 102 in a power-off state is obtained;
and S502, if the duration that the elevator 102 is in the power off state is longer than a third preset duration, determining that the elevator 102 is in the trapped state.
In this embodiment, the power supply disconnection state may be a state in which the 380V power supply in the elevator 102 is disconnected from the 380V detection module 204 in the monitoring terminal 104, at this time, the monitoring terminal 104 cannot collect relevant state information in the elevator in real time, and at this time, the monitoring terminal 104 may determine whether the elevator 102 is in a person trapping state according to the above steps S501 to S502. In step S501, if the elevator is in the power-off state, the monitoring terminal 104 may count the duration that the elevator 102 is stationary and the door of the elevator 102 is in the closed state, and when the duration is longer than a second preset duration, the duration that the elevator 102 is in the power-off state may be obtained, and according to the duration that the elevator 102 is in the power-off state, it is determined whether the elevator 102 is in the power-off and trapped state. If the elevator 102 is powered back on within the third predetermined time, it may be determined that the elevator 102 is out of the powered-off state. Otherwise, in step S502, if the duration that the elevator 102 is in the power-off state is longer than the third preset duration, which indicates that the elevator 102 has entered the power-off state, the monitoring terminal 104 may determine that the elevator 102 is in the power-off but trapped state by counting the duration that the elevator 102 is stationary and the doors of the elevator 102 are in the closed state. In this embodiment, under the condition that the elevator 102 is powered off, if the elevator 102 is stationary and the duration that the doors of the elevator 102 are in the closed state is longer than the second preset duration, the monitoring terminal 104 can more accurately determine whether the elevator 102 is in the trapped state by obtaining the time that the elevator 102 is in the power off state under the condition that the elevator 102 is powered off.
In one embodiment, after determining that the elevator 102 is trapped, the monitoring terminal 104 may perform at least one of the following steps: sending an intercom call signal to the intercom device 108 of the elevator 102 so that the intercom device 108 establishes a connection with the first monitoring center and makes a call; sending an alarm signal to the second monitoring center to enable a maintenance person of the second monitoring center to maintain the elevator 102; the first monitoring center is a local monitoring center 110 and the second monitoring center is a network monitoring center 106.
In this embodiment, the intercom device 108 may be a device disposed in the elevator 102, which may be in communication connection with the first monitoring center, i.e., the local monitoring center 110, by sending an intercom signal. The local monitoring center 110, which may be a facility for maintenance personnel in the local monitoring center 110 to perform maintenance on the elevator 102, may be located near the location of the elevator 102 to facilitate timely maintenance of the elevator 102 by maintenance personnel in the local monitoring center 110. When the elevator 102 is in a trapped state, the monitoring terminal 104 can send an intercom call signal to the intercom device 108 of the elevator 102, so that the intercom device 108 is connected with the first monitoring center and communicates with the first monitoring center, the first monitoring center can know the condition of passengers in the elevator 102 in time, and the first monitoring center can do a soothing work in time and organize rescue as soon as possible. The network monitoring center 106 may be a facility where the manufacturer of the elevator 102 is located, and the monitoring terminal 104 may transmit the status information of the elevator 102 to the network monitoring center 106 through a 3G/4G wireless module therein. The network monitoring center 106 can take corresponding measures by receiving the state information of the elevator 102 sent by the monitoring terminal 104. For example, when the elevator is in a trapped state, the monitoring terminal 104 may send elevator trapping information to the network monitoring center 106, so that an elevator manufacturer or a special inspection hall can obtain fault information of the elevator 102 in time, and send a professional to the site for rescue and maintenance as soon as possible.
In one embodiment, after determining that elevator 102 is in a trapped state, monitoring terminal 104 may determine that the trapped state is resolved when there is at least one door opening action on the elevator 102 door on the level floor and/or monitoring terminal 104 may determine that the trapped state is resolved when the power state of elevator 102 returns to normal and there is at least one door opening action on elevator 102 door on the level floor.
In this embodiment, the door opening operation may be performed by a door opening and closing system of the elevator 102, and the leveling may be an elevator leveling, or may be a slow operation of the elevator 102 when the elevator is normally stopped at a landing. After the monitoring terminal 104 determines that the elevator 102 is in the sleepy state, different sleepy state release conditions may be adopted according to whether the elevator 102 is sleepy in the power-on state or the power-off state. If the elevator 102 is trapped in the power-on state, the monitoring terminal 104 may determine that the trapped state is released by detecting that at least one door opening action of the elevator 102 door exists in the flat floor. When the elevator 102 is trapped in the power-off state, the monitoring terminal 104 can determine that the trapped state is released by detecting that the power state of the elevator 102 is recovered to normal and the door of the elevator 102 has at least one door opening action in the flat floor. In the embodiment, different conditions for releasing the trapped state are adopted for different trapped states, so that whether the elevator 102 releases the trapped state can be judged more comprehensively.
