All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In addition, the term "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In this context, unless otherwise specified, the term "/" generally indicates that the associated object is an "or" relationship.
The embodiment of the application provides a repeater communication method for multiple scenes, which is executed by electronic equipment, and referring to fig. 1, the method comprises steps S101-S107, wherein:
step S101, acquiring the use state of the elevator, wherein the use state comprises an operation state and a shutdown state.
In the embodiment of the application, the electronic equipment can acquire the use state of the elevator by acquiring the implementation operation data of the elevator in the main control equipment of the elevator in the elevator machine room, wherein the operation state comprises the state that the elevator operates up and down and waits for a user to enter; the off-stream condition includes the elevator remaining at a height for a time greater than a preset period. The preset period may be 10 minutes or 30 minutes, which is not specifically limited in the embodiment of the present application; meanwhile, the off-line state may also be various fault states of the elevator.
Step S102, if the elevator is in a use state, the number of people in the elevator car is determined.
In the embodiments of the present application, there are two ways to determine the number of people in the car. Mode 1: the terminal antenna can determine the SIM information of the terminal equipment based on the data uploaded and/or received by each terminal equipment, the quantity of the SIM information is the quantity of the terminal equipment, and then the quantity of the terminal equipment is determined as the number of people.
Mode 2: and acquiring a live-action image in the car, and determining the number of people based on the live-action image.
Specifically, image acquisition equipment is arranged in the elevator car, live-action images in the elevator car can be acquired, and the number of people in the elevator car can be determined by identifying human targets in the images.
Step S103, determining a power interval based on the number of people.
In this embodiment, when the number of people in the car is different, the overall demand for communication capability is also different, that is, the power demand for the repeater is not applicable. For example, when there are 3 persons, the repeater may only need 100W of power, and when there are 10 persons, the repeater may need 1500W of power. A mapping table of the number of persons and the power interval may be preset, and after the number of persons is determined, the power interval is determined based on the number of persons and the mapping table.
Step S104, obtaining the interval distance between the elevator car and the elevator machine room.
In the embodiment of the present application, there are two ways of obtaining the separation distance, namely, a way a and a way B. Mode a: and acquiring the current floor of the car, and determining the spacing distance based on the current floor of the car. When the electronic equipment acquires real-time running data of the elevator car in the main control equipment in the elevator machine room, the floor where the elevator car is located in the running data is acquired, and the spacing distance between the elevator machine room and the elevator car can be determined based on the preset heights of the floor and the unit floor and the height of the elevator machine room.
Mode B: measurement data of a distance sensor preset between the car and the elevator machine room are acquired, and the separation distance is determined based on the measurement data. Specifically, set up distance sensor at car top and/or elevator computer lab below, electronic equipment acquires distance sensor measuring data, and then can acquire the interval distance between car and the elevator computer lab in real time, and distance sensor can be ultrasonic wave type or infrared type.
Step S105, determining a loss coefficient corresponding to the interval distance based on the interval distance and a preset relation between the interval distance and the loss coefficient, wherein the loss coefficient and the interval distance are positively correlated.
In higher-rise houses, the height of the whole house may be 100m or more, the distance between the elevator car and the elevator machine room is changed, and the distance and the loss coefficient of the communication signal are positively correlated, that is, when the power of the repeater is fixed and the power of each antenna in the repeater is fixed, and when the number of people in the elevator car is fixed, the closer the distance between the elevator car and the elevator machine room is, the stronger the signal strength is, and the closer the distance between the elevator car and the elevator machine room is, the weaker the signal strength is.
Dividing the interval distance between a maximum value and a minimum value into a plurality of distance intervals, obtaining a curve relation between the interval distance and a loss coefficient through preliminary test measurement, and determining a corresponding relation between each distance interval and the loss coefficient based on the curve relation; after the interval distance is determined, a distance interval to which the interval distance belongs is determined, and then a loss coefficient is obtained.
Further, the minimum value of the power interval corresponding to the number of any person is larger than the power of the repeater station which can meet the minimum communication requirement of the number of any person when the interval distance between the elevator car and the elevator machine room is minimum; the minimum value of the power interval corresponding to the number of any person is larger than the power of the repeater station which can meet the minimum communication requirement of the number of any person when the distance between the elevator car and the elevator machine room is the largest.
Step S106, determining target power based on the power interval, the interval distance and the loss coefficient corresponding to the interval distance;
step S107, the power of the repeater is adjusted to the target power.
In the embodiment of the present application, the reserved power is first determined based on the power interval and the interval distance, and the target power=reserved power (1+loss coefficient). For example, if the determined reserved power is 1000W and the loss coefficient is 0.1, the target power is 1100W. Wherein the reserved power is equal to (distance interval x maximum value of power interval)/maximum value of distance interval. The power of the repeater is then adjusted based on the target power.
In the related art, no matter how far the elevator car is from the elevator machine room, and how many people are in the elevator car, the power of the repeater is always fixed, which causes that when the elevator is in a running state, the situation that the communication signals of the terminal devices of the people in the elevator car are poor possibly because of too many people in the elevator car and the interval distance is increased, or the situation that the elevator is in a stop state in a long time, the elevator is always fixed at a certain height, and the repeater has no terminal devices of users, and then certain resource waste is also caused. In the embodiment of the application, when the elevator is in a use state, the power interval to which the repeater needs to be adjusted is determined by determining and the number of people, meanwhile, when the elevator runs, the cage runs in the vertical direction to change the interval distance, and the electronic equipment acquires the interval distance and determines the loss coefficient of a signal based on the interval distance; and then the electronic equipment determines the target power based on the loss coefficient, the power interval and the interval distance, so that the power waste of the repeater is reduced under the condition of meeting the communication requirements of personnel in the car as much as possible.
Further, a power section is determined based on the number of persons, including step SA1 (not shown in the figure) -step SA3 (not shown in the figure), wherein:
step SA1, acquiring the current time, and determining a target time period to which the current time belongs from preset time periods.
Specifically, a day is divided into a plurality of time periods with a 24-hour period as a completed time period, and after the current time is acquired, the time period to which the current time belongs is determined as a target time period.
Step SA2, determining a required power interval of a single person based on a target time period;
and step SA3, determining a power interval based on the number of people and the required power interval.
Specifically, in different time periods, the required power intervals corresponding to the individual persons may be different, and after the required power of the individual person corresponding to the target time period is determined, the power interval is determined based on the number of persons and the required power interval of the individual person.
Further, a repeater communication method for multiple scenes further includes the step SB: and when the using state is determined to be in the off-line state, determining the number of people in the car, and if the number of people is greater than 0, adjusting the power of the repeater to be the preset power.
Specifically, when the elevator is in a stopped state, the car is always at a fixed height, and at this time, the car may not be used, or the elevator may be out of order, so that the user is trapped in the car. Therefore, by determining the number of people in the mode 1 and/or the mode 2, if the number of people is greater than 0, it is indicated that people are trapped in the car, and at this time, the power of the repeater is adjusted to the preset power, and the preset power may be a larger power, so that the user in the car can keep communication with the outside, but the specific value of the preset power is not specifically limited in the embodiment of the present application.
Further, a repeater communication method for multiple scenarios further comprises a step SC (not shown in the figure) and a step SD (not shown in the figure), wherein:
and step SD, if the number of people is 0 and the elevator is in a stop state, adjusting the power of the repeater to the second power.
Specifically, when no person is in the car and the elevator is in a shutdown state, the condition that no user uses the repeater is indicated, and the repeater is regulated to be in standby at a lower second power is provided, so that the waste of resources is reduced.
And step SC, if the number of people is 0 and the elevator is in an operating state, adjusting the power of the repeater to be the first power, wherein the first power is larger than the second power.
Specifically, when the number of users in the car is 0 and the elevator is in a running state, which means that the car is on the way to the floor called by the user, that is, that the user is about to enter the car, the power of the repeater is adjusted to be higher than the first power of the second power at the moment, so that the user can obtain a better communication signal when entering the car. The first power can acquire the number of people entering the elevator car each time the elevator car is called in a history period, and the required power corresponding to the mode of the number of people is determined to be the first power.
Further, when adjusting the repeater to any power, it includes a step SE1 (not shown in the figure) -a step SE4 (not shown in the figure), wherein:
and step SE1, determining a first influence coefficient of the distance between the current repeater and the elevator machine room on the communication signal.
Specifically, a mapping relationship between the interval distance and a first influence coefficient is preset, and the first mapping coefficient describes the influence degree of the interval distance on the communication signal.
And step SE2, determining a second influence coefficient of the number of people in the current elevator car on the communication signal.
Specifically, a mapping relation between the number of people and a second influence coefficient is preset, and the second influence coefficient describes the influence degree of the number of people on the communication signal.
Step SE3, determining the actual power corresponding to each antenna in the repeater based on the first influence coefficient, the second influence coefficient and any power;
and step SE4, adjusting each antenna in the repeater to the corresponding actual power.
Specifically, referring to fig. 2, any power is the total power of each antenna in the repeater; if the first influence coefficient is larger than the second influence coefficient, the interval distance is the main reason for influencing the communication signal, and the proportion of the power of the first transit antenna and the power of the second transit antenna in any power should be increased. If the second influence coefficient is larger than the first influence coefficient, the proportion of the power of the terminal antenna in any power should be increased.
