Specifically, the embodiments of the present application will be further explained below with reference to the drawings.
Example one
Fig. 1 is a schematic flow chart diagram of an elevator advertisement projection control method provided in a first embodiment of the present application, please refer to fig. 1, and the method includes, but is not limited to, the following steps:
step 110: the method comprises the steps of collecting an integral image and an elevator door image in the elevator, and projecting an advertisement after determining that a user takes the elevator in the elevator and the elevator door is in a closed state.
In the embodiment of the application, the step of collecting the whole image in the elevator comprises the step of collecting portrait information in the elevator to confirm whether a person takes the elevator, wherein the portrait information comprises information such as whether the person exists in the elevator and the height of the person, the specific implementation mode can be that an infrared camera is installed to scan the inside of the elevator through infrared rays and feed back whether the person exists, the height of the person is fed back under the condition that the person exists, the person can be scanned at a fixed time interval, the person can also be scanned when a weight sensor senses that the elevator stops or starts to run, and a user can set related parameters as required without being restricted by the setting of the embodiment of the invention. The specific implementation mode can be that the elevator door is scanned by infrared rays of infrared camera shooting, the elevator door is confirmed to be completely closed without gaps, a fixed time interval can be set for scanning, the weight sensor can also be used for scanning when the elevator stops or starts to run when sensing the elevator, and a user can set related parameters according to needs without being restricted by the setting of the embodiment of the invention. The "projecting advertisement after determining that a user takes the elevator in the elevator and the elevator door is in a closed state" includes sending a signal capable of projecting the advertisement after determining that the user is in the elevator and is in the closed state, specifically, the advertisement can be projected after the signal is received, or the advertisement can be projected after the signal is received for a period of time, and the user can set the advertisement according to needs.
Step 120: and collecting image information of buttons and a display board in the elevator.
The specific step of collecting the image information of the buttons in the elevator comprises collecting information of the number of floors corresponding to the buttons with the lighted backlights, wherein the information of the number of floors can be determined according to numbers (corresponding to the number of floors) on the buttons, or the information of the number of floors corresponding to each button position is stored in advance and is determined by matching the position of the lighted buttons with the stored information of the number of floors corresponding to the buttons. The "collecting image information of the display panel in the elevator" specifically includes collecting the floor number N1 of the current floor (stop floor) displayed on the display panel and the running state information of the elevator ascending or descending.
Step 130: and determining the closing operation time length of the elevator door between the current floor and the next target floor according to the image information.
In the embodiment of the application, a user can obtain necessary image information, and the processor processes the necessary image information and then calculates the closing operation time length of the elevator door. Fig. 2 is a schematic flow chart of specific steps of "determining the elevator door closing operation time length" in the first embodiment of the present application, please refer to fig. 2, which specifically includes, but is not limited to, the following steps:
step 310: and acquiring the floor number and the running state of the current floor of the elevator according to the image information of the display panel, wherein the running state comprises an uplink state and a downlink state.
In this embodiment of the present application, "obtaining the number of floors and the operating state of the current floor of the elevator" specifically includes: the floor number N1 of the current floor (stop floor) displayed on the display panel is acquired, and the up-going state or down-going state determined from the display panel is acquired.
Step 320: and determining the floor number of the next target floor according to the running state of the elevator and the image information of the buttons.
In the embodiment of the present application, "determining the number of floors of the next target floor according to the operation state and the button information" specifically includes: the floor number N2 of the next target floor is determined from the floor of the touch-controlled backlight-illuminated button (after a person presses the button, the button backlight is illuminated as a flag), and N2 is the number closest to N1 in the up state or the down state. For example, in the present embodiment, when the up-going state is determined, the target floor number N2 is greater than N1 (there may be a case where a person accidentally touches or intentionally presses the down-floor button when the elevator is in the up-going state, and the target floor number should be greater than the current floor number because the up-going state is determined), and the target floor number N2 is the number closest to N1.
Step 330: and determining the closing operation time length of the elevator door according to the floor number of the current floor, the floor number of the next target floor and the average operation time length of the adjacent floors. And the closed running time of the elevator door is the product of the difference between the information of the next target floor and the current floor and the running time of the adjacent floor.
Since the average speed of a conventional elevator in ascending or descending is different, it needs to be calculated in different ways.
For example, if the average operating time of the adjacent floors in the ascending state is T1, the elevator door closed operating time T1 is T1 (N2-N1). When the down state is determined, the target floor number N2 is less than N1 (when the elevator is down, a person may touch the down floor button by mistake or intentionally press the down floor button, and the target floor number N2 is determined to be the nearest number to N1 because the down state is determined, and if the operating time of the credential of the adjacent floor in the down state is T2, the elevator door closed operating time period T2 may be calculated to be T2 (N2-N1).
It should be noted that in this embodiment, the time lengths T1 and T2 of the elevator closed operation are calculated according to an ideal situation, ignoring the situation that the elevator enters after people touch the touch buttons on the floors outside the elevator take the elevator, for example: when a conventional office building ascends, the subsequent floors needing to stop are basically the target floors of touch buttons in the elevator, and few people wait for the elevator to go upwards from the middle floors; therefore, when the elevator goes upwards, the method for calculating the closed running time of the elevator door is more practical; of course, there is also an acceptable error in calculating the time length by calculating the average up or down running speed.
Therefore, in some other embodiments, the required operation acceleration corresponding to different floor numbers when the elevator goes upward or downward may also be input, the required operation acceleration corresponding to the number of floors passed by the upward or downward state between the current floor number and the target floor number is matched with the operation acceleration recorded by the system, if the required operation acceleration matches with the operation acceleration recorded by the system, it is indicated that no other person enters the elevator midway, if the required operation acceleration does not match with the operation acceleration, the current acceleration and the input operation acceleration may be matched, and the number of floors from the current floor corresponding to the current acceleration to the next floor may be obtained through matching, so that the next floor number may be calculated, and the elevator door closing operation time may be calculated. For example, the acceleration of the elevator passing through one floor in an ascending state is input as a1, the acceleration of the elevator passing through two floors is input as a2, the acceleration of the elevator passing through three floors is input as a3, and so on, … …, if the current floor number is 1 (floor 1), the floor number of the ascending nearest 1 selected by the user entering the elevator is 5 (floor 5), if no person outside the elevator needs to go upwards (the button of the ascending is pressed outside the elevator) in the process of the elevator running to floor 5, the acceleration of the elevator starting to run should be a4, if the running acceleration detected at this time is a1, it indicates that a person needs to go upwards in floor 2, the next target floor is determined to be floor 2, and the running time of the elevator door with the closing running time of 1 floor to floor 2, that is the running time of one floor, can be obtained through the above calculation.
In addition, because the up and down movement of the elevator has acceleration, the average running time of one floor is different when the elevator passes through floors with different numbers, so that the user can input the running times of the floors with different numbers under the condition of sufficient storage space, and the running time of the elevator with the corresponding floor number is matched as the closing running time of the elevator door after the floor number between the current floor and the next target floor is calculated.
Above-mentioned elevator is through the operating duration, the running acceleration of the floor of different quantity, adjacent elevator operation average speed etc. and the user can set up as required, need not be restricted to the utility model discloses the injeciton.
Step 140: and matching and projecting one or more advertisements with the total time length closest to the closed running time length of the elevator door.
In the embodiment of the application, the user can project the corresponding advertisement by matching the total time length of one or more advertisements with the total time length of the elevator door closing operation time. Fig. 3 is a schematic flow chart of the specific steps of "matching and projecting one or more advertisements having a total length of time closest to the length of time of the elevator door closed operation" in the first embodiment of the present application, please refer to fig. 3, which includes, but is not limited to, the following steps:
step 410: and acquiring the time length of all advertisements stored in the system, wherein the advertisements comprise a plurality of dynamic advertisements with different time lengths and a plurality of static advertisements.
In the embodiment of the application, a plurality of advertisements are stored, each advertisement has a corresponding time length parameter which can be obtained, the stored advertisements comprise dynamic advertisements and static advertisements, the time lengths of the dynamic advertisements can be the same or different, and the projection time length of the static advertisements can be set according to requirements.
Step 420: and matching one or more dynamic advertisements with the total time length closest to the closed running time length of the elevator door.
In the embodiment of the application, firstly, one or more dynamic advertisements closest to the elevator door closing operation time length are matched, and the "closest" can be a set time range. For example, when the elevator door closed operation time length is 30 seconds, an advertisement having a matching advertisement time length close to 30 seconds, and the "closest" time range is set to 3 seconds, then the advertisement having the advertisement time length in the range of 27-33 seconds among all the dynamic advertisements belongs to the advertisement having the time length closest to the elevator door closed operation time length. If there is no advertisement matching the advertisement having the advertisement duration closest to 30 seconds, then any two or more advertisements having the total duration that adds up to 30 seconds are automatically selected, for example, three advertisements for 9 seconds, three advertisements for 11 seconds, or two advertisements for 10 seconds and 7 seconds, and the system randomly selects a scenario. In other embodiments, the advertisement duration, the advertisement quantity, and the like may be set as needed and set as priority, and need not be limited by the embodiments of the present application.
Step 430: projecting the one or more dynamic advertisements and/or projecting one or more static advertisements, wherein,
if one or more dynamic advertisements with the total time length closest to the closed running time length of the elevator door are not matched, one or more static advertisements are projected;
and if the total time length of the one or more dynamic advertisements is less than the closed running time length of the elevator door, projecting one or more static advertisements after the one or more dynamic advertisements are projected.
In the embodiment of the application, one or more dynamic advertisements with the closest total time length and the closest elevator door closed operation time length are firstly matched, and if the one or more dynamic advertisements are not matched, one or more static advertisements are projected. And if the total time length of the projected dynamic advertisements is less than the closed running time length of the elevator door, one or more static advertisements are projected after the one or more dynamic advertisements are projected. If the total time length of the projected one or more dynamic advertisements is greater than or equal to the elevator door closed operation time length, only the one or more dynamic advertisements are projected, and the projection is stopped when the target floor is reached.
Still taking the example in step 420 as a basis for explanation, when the elevator door closed operation time length is 30 seconds, an advertisement with the advertisement time length close to 30 seconds is matched, and the "closest" time range is set to 3 seconds, then the advertisement with the advertisement time length in the range of 27-33 seconds belongs to the advertisement with the time length closest to the elevator door closed operation time length in all dynamic advertisements. The three advertisements of 9 seconds are the condition that the total time length of the plurality of projected dynamic advertisements is less than the closed running time length of the elevator door, in the closed running process of the elevator door, static advertisements can be projected, so that the total time length of the dynamic advertisements and the static advertisements is closer to the total closed running time length of the elevator door, the static advertisements can be one or more, and a user can control the number of the projected static advertisements by setting the time length of the static advertisements. For example, the projection time of the static advertisement is set to 1 second, then in the example of "three advertisements of 9 seconds", three static advertisements of 1 second can be projected in the process of the elevator door closing operation, the static advertisements can be projected after all the dynamic advertisements are projected, or the situation that the dynamic advertisements and the static advertisements are projected alternately can be set. The above-mentioned "three advertisements of 11 seconds" is the case that the total time length of the projected dynamic advertisements is longer than the elevator door closed running time length, this case only projects three advertisements, and when the elevator reaches the target floor and opens the elevator, cancels the projected advertisement or suspends the projected advertisement, the scheme of whether the total time length of the projected advertisement is longer than the elevator door closed running time length can be set according to the need, for example, in the above-mentioned scheme, because the set "closest" time range is set to 3 seconds, the phenomenon of matching to three advertisements of 11 seconds "can occur, if these three advertisements are projected, the last three seconds of the last advertisement will not be projected, this scheme may affect the experience of the viewer, therefore, this scheme can be set to be automatically screened out, and if the set" closest "time range is set to 0.5 seconds, this may have little impact on the viewer's experience and the viewer can obtain the required information through the preceding advertisement segment, at which time the advertisement projection scheme may be retained. The multiple schemes and the arrangement mode can be arranged according to needs and do not need to be limited by the embodiment of the application.
The above scheme of projecting one or more static advertisements, that is, "if one or more dynamic advertisements whose total duration is closest to the closed operation duration of the elevator door are not matched" is that there may be an advertisement whose storage duration is not short, or an advertisement whose total duration is less than or equal to the closed operation duration of the elevator door cannot be matched due to the fast operation speed of the elevator. For example, the current common dynamic advertisements are generally more than 5 seconds, if the advertisement with the shortest storage time is 7 seconds, the number of floors passing between the current floor and the next floor is only one floor, and the closed operation time of the elevator is only 5 seconds, in this case, one static advertisement can be projected continuously or posted, the projection time of each static advertisement can be set according to needs, so that a viewer can completely view one or more advertisement messages, and the obtained advertisement effect is better.
It is worth mentioning that the user can set which projection scheme is selected according to the priority setting, for example, one or more advertisements with the advertisement total time length closest to the elevator door closed operation time length are projected preferentially, advertisements with the advertisement total time length closest to the elevator door closed operation time length but with the advertisement total time length less than or equal to the elevator door closed operation time length are projected preferentially, the latest recorded advertisements are projected preferentially, the advertisements with the minimum projection times are projected preferentially, and the like. The user can set the scheme according to the needs, and the scheme is not limited to the above mentioned scheme, and the definition of the embodiment of the application is not required to be limited.
In addition, the range and height of the projection may also be set to a certain value or the projection may be performed as required, for example, when the height of the person in the elevator is small, a little lower height may be projected, and when the height of the person in the elevator is high, a little higher height may be projected, and the height of the person may be determined by the shooting of the infrared camera in the above step 110.
The embodiment provides an elevator advertisement projection control method, which is used for calculating the closed running time of an elevator door by acquiring shot image information and matching and projecting corresponding advertisements. By the method of the embodiment, the user can completely watch one or more advertisement messages, and a better advertisement effect is obtained.
