Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
One of the core ideas of the embodiment of the invention is to provide a novel elevator door detection method, which judges the situation by utilizing the characteristic of the A-shaped elevator door panel and combining an elevator light curtain, thereby avoiding the situation that the elevator runs when the lower end of the elevator door panel is clamped by foreign matters and is in the A-shaped state, solving the problem of potential safety hazard existing in normal running of the conventional elevator when the elevator door is not completely closed, and ensuring the safety of elevator passengers and the elevator door.
It should be noted that, during normal elevator door control, the following characteristics exist: when the elevator is completely closed under normal conditions, the door panels at the upper and lower ends are completely closed, as shown in fig. 2; when the lower extreme of elevator door plant was blocked by the foreign matter, because power system is located the upper portion of door plant, power system gives certain moment to the elevator door plant, and the door plant can be A style of calligraphy, and as shown in figure 1, elevator light curtain installs on the elevator door plant, so the light curtain also is the characteristics of A style of calligraphy. Specifically, the distances between each light emitting point and each light receiving point on the elevator light curtain are not consistent, and the light intensities collected by the light receiving tubes are different, as shown in fig. 3, a distance S1 between a first elevator light curtain receiving tube R1 mounted on the elevator door and a first elevator light curtain receiving tube T1 corresponding thereto, a distance S2 between a second elevator light curtain receiving tube R2 and a second elevator light curtain receiving tube T2 corresponding thereto, a distance S3 between a third elevator light curtain receiving tube R3 and a third elevator light curtain receiving tube T3 corresponding thereto, and a distance S4 between a fourth elevator light curtain receiving tube R4 and a fourth elevator light curtain receiving tube T4 corresponding thereto are not equal, that is, S1, S2, S3, and S4 are not equal, so that the light intensities collected by a first elevator light curtain receiving tube R1, the light intensities collected by a second elevator light curtain receiving tube R2, the light intensities collected by a third elevator light curtain receiving tube R3, and the light intensities collected by a fourth elevator light curtain R4 are different, therefore, the embodiment of the invention can judge whether the elevator door is completely closed or not through different light intensities.
Referring to fig. 4, a flowchart illustrating steps of a method for detecting an elevator door according to an embodiment of the present invention is shown. The embodiment is applicable to the detection situation of the elevator door, and as shown in fig. 4, the detection of the elevator door specifically includes the following steps:
and step 410, determining light intensity information according to the receiving tube signal of the elevator light curtain.
In the embodiment of the present invention, the light receiving signal of the elevator light curtain may refer to a signal received by an elevator light curtain receiving tube, and specifically may include an infrared light signal received by each elevator light curtain receiving tube installed on an elevator door panel, and as shown in fig. 3, the light receiving signal may include an infrared light signal received by a first elevator light curtain receiving tube R1, an infrared light signal received by a second elevator light curtain receiving tube R2, an infrared light signal received by a third elevator light curtain receiving tube R3, an infrared light signal received by a fourth elevator light curtain receiving tube R4, and the like, which is not limited in this embodiment of the present invention.
In the actual processing, after the receiving tube signal of the elevator light curtain is obtained, the receiving tube signal can be converted into the light intensity signal through circuit collection, and then the corresponding light intensity information can be determined based on the light intensity signal, so that whether the elevator door is closed or not can be determined according to the light intensity information. The light intensity information can be used for representing the light intensity of the elevator light curtain receiving light points, and specifically can include light intensity information corresponding to each elevator light curtain receiving tube. It should be noted that the light intensity information corresponding to the elevator light curtain receiving tube can be used to indicate the light intensity received by the elevator light curtain receiving tube.
And step 420, judging whether the elevator door enters a closed state or not according to the light intensity information.
Specifically, under the condition that the power of the elevator light curtain transmitting tube is set to be constant, when the elevator is closed, the distance between the elevator light curtain transmitting tube and the elevator light curtain receiving tube is closer and closer, and the intensity of light received by the elevator light curtain receiving tube is also larger and larger at the moment, namely the received light intensity is in an ascending trend; when the elevator is completely closed, the elevator door does not operate, the distance of the light curtain does not change at the moment, namely the distance between the elevator light curtain transmitting tube and the elevator light curtain receiving tube corresponding to the elevator light curtain transmitting tube does not change, and the light intensity received by the elevator light curtain receiving tube does not change. Therefore, after the light intensity information is determined, the embodiment of the present invention may determine whether the elevator door enters the closed state based on the light intensity information, and if the light intensity unchanged duration time exceeds the preset time threshold value based on the light intensity information, the embodiment of the present invention may determine that the elevator door is in the closed state, and then execute step 430.
Of course, the embodiment of the present invention may determine whether the elevator door is closed by using the duration time of unchanged light intensity, and may also determine whether the elevator door enters the closed state by using other manners, for example, determine whether the elevator door enters the closed state by determining whether the light intensity is larger and larger, and/or determine whether the elevator door enters the closed state by determining whether the light intensity exceeds a preset light intensity threshold, and the like.
And 430, if the elevator door panel enters a closed state, switching the elevator light curtain into a closed monitoring state, and judging whether the elevator door is completely closed according to the light intensity value information corresponding to each elevator light curtain receiving tube in the closed monitoring state.
Wherein, the light intensity information corresponding to the elevator light curtain receiving tube can be used for expressing the light intensity received by the elevator light curtain receiving tube. Specifically, after the elevator door is judged to be in the closed state, the elevator light curtain can be switched to the closed monitoring state, so that whether the elevator door is completely closed or not is determined by judging whether the light intensity received by each elevator light curtain receiving tube is equal or not in the closed monitoring state. If the light intensity received by each elevator light curtain receiving tube is equal, namely when the light intensity received by each elevator light curtain receiving tube is consistent, the elevator door can be determined to be completely closed; otherwise, that is, when the light intensities received by the respective elevator light curtain receiving pipes are not consistent, it may be determined that the elevator doors are not completely closed, and then step 440 is performed.
And step 440, if the elevator door is not completely closed, sending a light curtain signal to an elevator main control board, wherein the light curtain signal is used for triggering the elevator main control board to open the elevator door again.
Specifically, when the embodiment of the invention judges that the elevator door is not completely closed, for example, when the lower end of the elevator door is clamped by a foreign matter in a drawing, the embodiment of the invention can send a light curtain signal to the elevator main control board, so that the elevator main control board can reopen the elevator door according to the light curtain signal, thereby avoiding the normal operation of the elevator car under the condition that the elevator door is not completely closed, and ensuring the safety of elevator passengers and the elevator.
Therefore, the embodiment of the invention determines the light intensity information according to the receiving tube signals of the elevator light curtain and judges whether the elevator door enters the closing state or not according to the light intensity information, so that the elevator light curtain can be switched to the closing monitoring state when the elevator door panel enters the closing state, whether the elevator door is completely closed or not is judged according to the light intensity value information corresponding to each elevator light curtain receiving tube in the closing monitoring state, and then the light curtain signals can be sent to the elevator main control board when the elevator door is not completely closed, so that the elevator main control board reopens the elevator door, the potential safety hazard problem of normal operation of the elevator in the prior art when the elevator door is not completely closed is solved, the safety of elevator passengers and the elevator door is ensured, and the safety of the elevator is improved.
In practical processing, the receiving tube signals in the embodiment of the invention comprise infrared light signals received by the receiving tubes of the elevator light curtains arranged on the elevator door panel. On the basis of the above embodiment, optionally, the determining light intensity information according to the receiving tube signal of the elevator light curtain in the embodiment of the present invention includes: converting infrared light signals received by each elevator light curtain receiving tube into light intensity signals through a circuit acquisition module; corresponding light intensity information is generated based on the light intensity signal. Therefore, the light intensity change information can be determined based on the light intensity information, whether the elevator door enters the closed state or not can be determined based on the light intensity change information, whether the elevator door is completely closed or not can be judged according to the light intensity information corresponding to each elevator light curtain receiving tube after the elevator door enters the closed state, and therefore the elevator door can be triggered to be re-opened by sending the light curtain signal to the elevator main control board when the elevator door is not completely closed, the problem of potential safety hazard in normal operation of the elevator when the elevator door is not completely closed in the prior art is solved, and the safety of elevator passengers and the elevator door is ensured.
Further, after determining that the elevator door is not completely closed, the method for detecting an elevator door according to the embodiment of the present invention may further include: generating prompt information corresponding to the condition that the elevator door is not completely closed; and outputting according to the prompt information to prompt passengers in the elevator car that foreign matters exist between the elevator doors, so that the safety of the passengers and the elevator doors is protected.
Referring to fig. 5, a flow chart of the steps of a method of detecting an elevator door in an alternative embodiment of the invention is shown. The detection method of the elevator door specifically comprises the following steps:
and step 510, converting the infrared light signals received by the elevator light curtain receiving tubes into light intensity signals through a circuit acquisition module.
Specifically, after the infrared light signals received by the elevator light curtain receiving tubes installed on the elevator door panel are acquired, the infrared light signals received by the elevator light curtain receiving tubes can be converted into light intensity signals through the circuit acquisition module, so that light intensity information corresponding to the elevator light curtain receiving tubes can be determined according to the light intensity signals, and then step 520 is executed.
And step 530, judging whether the elevator door enters a closed state or not according to the light intensity information.
Further, the embodiment of the present invention determines whether the elevator door enters the closed state according to the light intensity information, and specifically may include: determining light intensity variation information based on the light intensity information; judging whether the light intensity information accords with a preset door closing rule or not based on the light intensity change information; and if the light intensity information accords with a preset door closing rule, judging that the elevator door enters a closed state. The light intensity variation information may be used to indicate a variation of the light intensity within a period of time, such as a variation of the light intensity within one second or three seconds, and the present embodiment does not specifically limit this.
Specifically, after the light intensity information corresponding to each elevator light curtain receiving tube is determined, the light intensity change information of each elevator light curtain receiving tube within a certain time can be determined based on the light intensity information corresponding to each elevator light curtain receiving tube, the change situation of the light intensity received by each elevator light curtain receiving tube within the certain time can be determined based on the light intensity change information, and further, whether the elevator door enters the door closing state can be determined by judging whether the change situation of the light intensity received by each elevator light curtain receiving tube within the certain time meets the gradual rising trend of the light intensity collected by the receiving tube when the door is closed. Specifically, if the variation of the light intensity received by each elevator light curtain receiving tube meets the gradual rising trend of the light intensity, it can be determined that the light intensity information corresponding to the elevator light curtain receiving tube meets the preset door closing rule, and it can be determined that the elevator door enters a door closing state, and then step 540 is executed; otherwise, namely when the change condition of the light intensity received by the elevator light curtain receiving tube does not accord with the gradual rising trend of the light intensity, if the light intensity received by the elevator light curtain receiving tube is kept unchanged, the elevator door can be determined to be in the door opening or closing state, namely, the light intensity information corresponding to the elevator light curtain receiving tube is judged to be not in accordance with the preset door closing rule, so that the elevator door can be judged not to enter the door closing state, then, the procedure returns to step 510, to continue to detect whether the elevator door enters the closed state diagram based on the infrared light signals received by the elevator light curtain receiving tubes, so that the elevator light curtain can be switched to the closed monitoring state when the elevator door is detected to enter the closed state, and judging whether the elevator door is completely closed according to the light intensity value information corresponding to each elevator light curtain receiving tube in the closed monitoring state, so as to ensure the safety of elevator passengers and the elevator door.
And 540, if the elevator door panel enters a closed state, switching the elevator light curtain to a closed monitoring state.
And 550, judging whether the elevator door is completely closed or not according to the light intensity value information corresponding to each elevator light curtain receiving tube in the closing monitoring state.
In an optional implementation manner, in the embodiment of the present invention, in the closing monitoring state, determining whether the elevator door is completely closed according to the light intensity value information corresponding to each elevator light curtain receiving tube may specifically include: monitoring whether light intensity value information corresponding to each elevator light curtain receiving tube changes or not; if the light intensity value information corresponding to each elevator light curtain receiving tube is monitored to be kept unchanged, recording the duration time of unchanged light intensity; when the light intensity unchanged duration time reaches a preset duration time threshold value, closing the transmitting tubes corresponding to the elevator light curtain receiving tubes, and recording closing light intensity information corresponding to the elevator light curtain receiving tubes; and judging whether the elevator door is completely closed or not based on the closing light intensity information corresponding to each elevator light curtain receiving tube. The closed light intensity information corresponding to the elevator light curtain receiving tube can represent the light intensity collected by the elevator light curtain receiving tube after the transmitting tube corresponding to the elevator light curtain receiving tube is closed, for example, the light intensity collected by the elevator light curtain receiving tube after all transmitting tubes of the elevator light curtain are closed; the preset duration threshold may be set according to the determination requirement, for example, may be set to 0.5 second, 1 second, and the like, which is not specifically limited in this embodiment.
Specifically, after the closing light intensity information corresponding to each elevator light curtain receiving tube is recorded, whether the elevator door is completely closed can be judged by judging whether the closing light intensity information corresponding to each elevator light curtain receiving tube is the same or not. If the closing light intensity value information corresponding to each elevator light curtain receiving tube is the same, namely the light intensity collected by each elevator light curtain receiving tube is the same, the distances between each elevator light curtain receiving tube and the corresponding transmitting tube can be determined to be the same, and the elevator door can be judged to be completely closed; if the closing light intensity value information corresponding to each elevator light curtain receiving tube is different, namely the light intensity collected by each elevator light curtain receiving tube is different, the distance between each elevator light curtain receiving tube and the corresponding transmitting tube can be determined to be different, and the elevator door can be judged not to be completely closed.
As an example of the present invention, as shown in fig. 3, a first elevator light curtain transmitting tube T1 and a first elevator light curtain receiving tube R1 installed at an elevator door may be set as a pair of light points to establish a correspondence between the first elevator light curtain transmitting tube T1 and the first elevator light curtain receiving tube R1; similarly, the second elevator light curtain transmitting tube T2 and the second elevator light curtain receiving tube R2 can be set as a pair of light points to establish a corresponding relationship between the second elevator light curtain transmitting tube T2 and the second elevator light curtain receiving tube R2; setting a third elevator light curtain transmitting tube T3 and a third elevator light curtain receiving tube R3 as a pair of light points to establish a corresponding relationship between the third elevator light curtain transmitting tube T3 and the third elevator light curtain receiving tube R3; and setting the fourth elevator light curtain transmitting tube T4 and the fourth elevator light curtain receiving tube R4 as a pair of light points to establish a correspondence between the fourth elevator light curtain transmitting tube T4 and the fourth elevator light curtain receiving tube R4.
When the elevator door is closed, the distance between the elevator light curtain transmitting tube and the elevator light curtain receiving tube is closer and closer, the light intensity received by the elevator light curtain receiving tube is larger and larger at the moment, the light intensity shows a rising trend, and when the distance between the elevator door is not changed any more, the light intensity received by the elevator light curtain receiving tube is not changed, so that the light intensity value information corresponding to each elevator light curtain receiving tube can be monitored to be kept unchanged, and the duration time of the light intensity can be recorded. After the light intensity does not change for the duration time T, namely when the light intensity does not change for the duration time T and reaches the preset duration time threshold value T, the elevator door can be judged to be in a closed state, and the elevator light curtain can be switched to be in a closed monitoring state.
After the elevator light curtain is switched to the closed monitoring state, all the transmitting tubes on the elevator light curtain can be closed, namely the elevator light curtain is switched to the closed state for monitoring, at the moment, because of the relation of natural light, the light intensity can still be collected by the elevator light curtain receiving tubes, the light intensity collected by each elevator light curtain receiving tube can be recorded as WR01, WR02, WR03 and WR04 … … WR0n, wherein WR01 can represent the light intensity collected by a first elevator light curtain receiving tube R1 installed on the elevator door panel after the elevator light curtain is completely transmitted, WR02 can represent the light intensity collected by a second elevator light curtain receiving tube R2 installed on the elevator door panel after the elevator light curtain is completely transmitted, WR03 can represent the light intensity collected by a third elevator light curtain receiving tube R3 installed on the elevator door panel after the elevator light curtain is completely transmitted, WR04 can represent the light intensity collected by a fourth elevator light curtain receiving tube R4 installed on the elevator door panel after the elevator light curtain is completely transmitted, and then By analogy with the light intensity … …, WR0n may represent the light intensity collected by the nth elevator light curtain receiving tube Rn installed on the elevator door panel after the elevator light curtain is closed to emit light completely, and n is an integer greater than zero.
Subsequently, whether the elevator doors are completely closed can be determined by determining whether the light intensities collected by the elevator light curtain receiving tubes are equal, as shown in fig. 6, when WR01, WR02, WR03 and WR04 are equal, it can be determined that the elevator doors are completely closed, that is, when the distance S1 between the first elevator light curtain receiving tube R1 and the first elevator light curtain receiving tube T1, the distance S2 between the second elevator light curtain receiving tube R2 and the second elevator light curtain receiving tube T2, the distance S3 between the third elevator light curtain receiving tube R3 and the third elevator light curtain receiving tube T3, and the distance S4 between the fourth elevator light curtain receiving tube R4 and the fourth elevator light curtain receiving tube T4 are all fixed values, that is, when S1 is S2 is S3 is S4; when WR01, WR02, WR03 and WR04 are not equal, as shown in fig. 7, when WR01> WR02> WR03> WR04, that is, when the distance S1 between the first elevator light curtain receiving tube R1 and the first elevator light curtain receiving tube T1, the distance S2 between the second elevator light curtain receiving tube R2 and the second elevator light curtain receiving tube T2, the distance S3 between the third elevator light curtain receiving tube R3 and the third elevator light curtain receiving tube T3, and the distance S4 between the fourth elevator light curtain receiving tube R4 and the fourth elevator light curtain receiving tube T4 are not equal, that is, S1> S2> S3> S4, it can be determined that the lower end of the elevator door is blocked by a foreign object, and it can be determined that the elevator door is not completely closed. Note that t in fig. 6 and 7 may represent time.
Further, in the embodiment of the present invention, in the closed monitoring state, determining whether the elevator door is completely closed according to the light intensity value information corresponding to each elevator light curtain receiving tube may specifically include: monitoring whether light intensity value information corresponding to each elevator light curtain receiving tube changes or not; if the light intensity value information corresponding to each elevator light curtain receiving tube is monitored to be kept unchanged, recording the duration time of unchanged light intensity; when the light intensity unchanged duration time reaches a preset duration time threshold value, closing the transmitting tubes corresponding to the elevator light curtain receiving tubes, and recording closing light intensity information corresponding to the elevator light curtain receiving tubes; and judging whether the elevator door is completely closed or not based on the closing light intensity information corresponding to each elevator light curtain receiving tube.
For example, in combination with the above example, after the elevator light curtain is switched to the off state for monitoring, all the emitting tubes on the elevator light curtain may be turned off, for example, the first elevator light curtain emitting tube T1, the second elevator light curtain emitting tube T2, the third elevator light curtain emitting tube T3 and the fourth elevator light curtain emitting tube T4 in fig. 3 are turned off, after the light intensity collected by each elevator light curtain receiving tube under the natural light condition is obtained, that is, after the intensity of the natural light is collected, the first elevator light curtain emitting tube T1, the second elevator light curtain emitting tube T2, the third elevator light curtain emitting tube T3 and the fourth elevator light curtain emitting tube T4 may be turned on one by one and emit infrared rays with the intensity of W1, so that the infrared rays of the light spots of the corresponding first elevator light curtain receiving tube R1, the second elevator light curtain receiving tube R2, the third elevator light curtain receiving tube R3 and the fourth elevator light receiving tube R4 may be emitted one by one, and can convert the received infrared light signal into received light intensity value WR1, WR2, WR3, WR4, wherein, WR1 can show the light intensity that first elevator light curtain receiver tube R1 installed on the elevator door board gathered after first elevator light curtain transmitting tube T1 opens, WR2 can show the light intensity that second elevator light curtain transmitter tube T2 installed on the elevator door board gathered after opening, WR3 can show the light intensity that third elevator light curtain receiver tube R3 installed on the elevator door board gathered after third elevator light curtain transmitter tube T3 opens, WR4 can show the light intensity that fourth elevator light curtain receiver tube R4 installed on the elevator door board gathered after fourth elevator light curtain transmitter tube T4 opens. Subsequently, whether the elevator door is completely closed can be determined by determining whether the light intensity values WR1, WR2, WR3 and WR4 are equal, that is, whether the closing light intensity information corresponding to the respective elevator light curtain receiving tubes is the same. If the light intensity values WR1, WR2, WR3 and WR4 are equal, that is, WR1 is WR2, WR3 is WR4, it can be determined that the elevator door is completely closed, that is, it can be determined that the elevator door is completely closed when the closing light intensity information corresponding to each elevator light curtain receiving tube is the same; if the light intensity values WR1, WR2, WR3 and WR4 are not equal, such as WR1< WR2< WR3< WR4, it can be determined that the elevator door is not completely closed, that is, the closed light intensity information corresponding to the elevator light curtain receiving tubes is different, and then step 570 is performed.
Furthermore, in the embodiment of the present invention, when the closing light intensity information corresponding to each elevator light curtain receiving tube is different, the closing light intensity information corresponding to each elevator light curtain receiving tube may be compared with the opening light intensity information of each elevator light curtain receiving tube to determine the light intensity difference information corresponding to each elevator light curtain receiving tube, so as to determine whether the elevator door is completely closed according to the light intensity difference information corresponding to each elevator light curtain receiving tube, thereby determining that the elevator door is completely closed when the light intensity difference information corresponding to each elevator light curtain receiving tube is consistent, and determining that the elevator door is not completely closed when the light intensity difference information corresponding to each elevator light curtain receiving tube is inconsistent. The light intensity difference information corresponding to the elevator light curtain receiving tube can be used for representing the intensity difference between the light intensity collected when the corresponding transmitting tube of the elevator light curtain receiving light is opened and the light intensity when the transmitting tube is not opened.
Optionally, the embodiment of the present invention determines whether the elevator door is completely closed based on the closing light intensity information corresponding to each elevator light curtain receiving tube, and specifically may include: calculating by respectively adopting the closing light intensity information corresponding to each elevator light curtain receiving tube and the opening light intensity information of each elevator light curtain receiving tube to obtain light intensity difference information corresponding to each elevator light curtain receiving tube; judging whether the light intensity difference information corresponding to each elevator light curtain receiving tube is the same or not; if the light intensity difference information corresponding to each elevator light curtain receiving tube is the same, judging that the elevator door is completely closed; otherwise, the elevator door is judged not to be completely closed. Wherein, the opening light intensity information of the elevator light curtain receiving tube is the light intensity information of the elevator light curtain receiving tube when the corresponding transmitting tube is opened alone. Further, after recording the closing light intensity information corresponding to each elevator light curtain receiving tube, the embodiment of the present invention may further include: and opening the transmitting tubes corresponding to the elevator light curtain receiving tubes one by one according to the preset infrared light emission intensity, and acquiring light intensity information of the elevator light curtain receiving tubes when the corresponding transmitting tubes are opened independently to serve as the opening light intensity information.

For example, in combination with the above example, when the lower end of the elevator door is blocked by a foreign object, at this time, due to the a-shaped door, the elevator light curtain presents a certain angle, and when all the transmitting tubes of the elevator light curtain are closed, since the larger the gap is, the stronger the natural light is, the light intensities collected by the elevator light curtain receiving tubes are unequal, as shown in fig. 7, the light intensities WR01> WR02> WR03> WR 04; when the elevator light curtain transmitting tubes are opened one by one, the distances between each pair of light points are inconsistent, the closer the distance is, the higher the light intensity is, and at the moment, the recorded light intensity WR1< WR2< WR3< WR4, therefore, the calculated light intensity difference information (WR1-WR01), (WR2-WR02), (WR3-WR03) and (WR4-WR04) corresponding to each elevator light curtain receiving tube are different, as shown in FIG. 6, (WR1-WR01) < (WR2-WR02) < (WR3-WR03) < (WR4-WR04), so that the elevator door can be judged to be not completely closed. If the elevator door is normally closed, the light intensity received by each elevator light curtain receiving tube should be consistent, that is, WR01 is WR02 is WR03 is WR04, WR1 is WR2 is WR3 is WR4, as shown in fig. 6, so that the calculated light intensity difference information (WR1-WR01), (WR2-WR02), (WR3-WR03) and (WR4-WR04) corresponding to each elevator light curtain receiving tube are the same, that is, (WR 59 3 4-WR 01) is (WR2-WR02) is (WR2-WR 03) is (WR4-WR04), and thus the elevator door can be judged to be completely closed.
And 560, if the elevator door is not completely closed, sending a light curtain signal to the elevator main control board, and generating a prompt message corresponding to the situation that the elevator door is not completely closed.
And step 570, outputting according to the prompt information.
