In the communication method provided by the application, after the base station equipment determines that the current output power reaches the preset maximum output power, the gain indication is sent to the follow-up equipment, so that the follow-up equipment responds to the gain indication to process the wireless signal, and network coverage in the elevator is ensured. In this way, the output signal quality of the base station equipment is stable, and the problem of elevator network coverage of higher floors can be solved by matching with the gain adjustment of the follow-up equipment.
Fig. 2 shows a communication system, and the communication method provided in the embodiment of the application can be applied to the communication system shown in fig. 2, so as to solve the problem of network coverage in an elevator. As shown in fig. 2, the communication system 20 includes a base station apparatus 21 and a follower apparatus 22.
Wherein the base station device 21 can communicate wirelessly with the receiving antenna of the follower device 22 via the transmitting antenna of the base station device 21, and the follower device 22 can provide network coverage for the elevator via the transmitting antenna of the follower device 22. The antenna shown in fig. 2 does not constitute a limitation on the number of antennas of the base station apparatus 21 and the follower apparatus 22.
The base station apparatus 21 may be disposed at the top of the elevator hoistway or at the bottom of the elevator hoistway, and in the communication system shown in fig. 2, the base station apparatus 21 is disposed at the top of the elevator hoistway.
With the base station apparatus 21 deployed on top of the elevator hoistway, the follower apparatus 22 is deployed on top of the elevator car; in the case of a base station apparatus 21 disposed at the bottom of the elevator hoistway, a follower apparatus 22 is disposed at the bottom of the elevator car for providing network coverage for the elevator.
The base station device 21 may be a small base station and a micro base station, or a remote device of a small base station and a remote device of a micro base station, which is not particularly limited in the embodiment of the present application.
The base station device 21 further comprises a ranging module for enabling a determination of the distance between the base station device 21 and the follower device 22.
The base station device 21 may also be adapted to adjust the current output power of the transmitted wireless signal in accordance with the determined distance so that the follower device 22 can receive the wireless signal transmitted by the base station device 21 with a stable input power, providing network coverage for the elevator.

The follower device 22 may be configured to gain the wireless signal transmitted by the base station device 21 after receiving the gain indication transmitted by the base station device 21, thereby providing network coverage for the elevator.
Fig. 3 is a flow diagram illustrating a method of communication according to some example embodiments. In some embodiments, the above-described communication method may be applied to the base station apparatus 21 in the communication system 20 as shown in fig. 2. Hereinafter, the present embodiment will be described with reference to the case where the communication method is applied to the base station apparatus 21.
As shown in fig. 3, the communication method provided in the embodiment of the present application includes the following S301 to S303.
S301, the base station equipment determines the current output power of the wireless signal transmitted to the follow-up equipment by the base station equipment.
As a possible implementation manner, since the wireless signal causes power loss due to the increase of the distance during the transmission process, in order to ensure the input power of the slave device, the base station device monitors the input power of the slave device and adjusts the current output power of the wireless signal according to the input power of the slave device.
The base station device may monitor the input power of the slave device, where the base station device periodically obtains the input power fed back by the slave device; the method may also include sending, by the slave device, a request to adjust the current output power to the base station device after determining that the input power is lower than a preset minimum input power threshold or higher than a preset maximum input power threshold. The preset minimum input power threshold is the minimum input power which can normally provide network coverage for the elevator based on the input power of the follow-up equipment; the preset maximum input power threshold is the maximum output power of the wireless signal sent by the base station equipment, which does not cause interference to the wireless signal output by the follow-up equipment.
In some embodiments, the base station device may also adjust the current output power of the transmitted wireless signal according to the distance between the base station device and the follower device, transmitting the wireless signal with a lower output power when the distance is smaller, and increasing the output power when the distance is larger.
The specific implementation manner of how the base station device adjusts the current output power according to the distance may be described later with reference to the embodiments of the present application, and will not be described here again.
S302, the base station equipment determines whether the current output power is equal to a preset maximum power.
The preset maximum power is the rated maximum output power of the base station equipment.
As a possible implementation manner, the base station apparatus determines whether to transmit the wireless signal at the rated maximum output power currently, based on the current output power determined in the above step S301, compared with the preset maximum power.
And S303, the base station equipment sends a gain instruction to the follow-up equipment under the condition that the current output power is equal to the preset maximum power.
The gain indication is used for indicating the follow-up device to start to adjust the gain of the follow-up device after receiving the wireless signal, and processing the received wireless signal based on the adjusted gain.
As a possible implementation manner, in the case where the base station device determines in the above step S302 that the current output power is equal to the preset maximum power, the base station device generates a gain instruction, and sends the gain instruction to the slave device.
Correspondingly, the follow-up device receives the gain indication and adjusts the gain of the follow-up device according to the gain indication.
In some embodiments, the base station device includes a ranging module to determine a distance between the base station device and the follower device.
The gain indication sent by the base station equipment to the follow-up equipment also comprises the distance between the base station equipment and the follow-up equipment
In the case that the gain indication includes a distance between the base station device and the follower device, the gain indication is used for indicating the follower device to adjust the gain of the follower device according to the distance after receiving the wireless signal, and processing the received wireless signal based on the adjusted gain.
It can be understood that, in the above communication method provided by the application, the output power of the base station device is adjusted to ensure the input power of the follow-up device, and under the condition that the network coverage of the elevator cannot be ensured by adjusting the output power of the base station device, the base station device sends a gain indication to the follow-up device, so that the follow-up device adjusts the gain, provides network coverage for the elevator, and ensures the network use experience of a user.
In one design, in order to avoid that when the distance between the base station device and the follow-up device is relatively short, the output power of the base station device is too high, so that the saturated signal of the follow-up device is distorted to generate error codes, and the input power of the follow-up device is ensured, as shown in fig. 4, the communication method provided by the embodiment of the application further includes S401-S404.
S401, the base station equipment determines the distance between the base station equipment and the follow-up equipment.
As a possible implementation manner, the base station device includes a ranging module, and the distance between the base station device and the follow-up device is determined based on the ranging module.
It should be noted that, the ranging module may be a radar or an infrared laser device built in the base station apparatus, which is not limited in the embodiment of the present application.
In some embodiments, the base station device determines the distance between the base station device and the follower device based on the wireless signal transmission time and the reception time between the base station device and the follower device.
For example, after receiving a distance measurement instruction sent by the slave device, the base station device records a receiving time t1, where the distance measurement instruction includes a sending time t2 of a wireless signal sent by the slave device, and the distance measurement instruction is used to instruct the base station device to determine a distance L between the base station device and the slave device, and if a transmission rate of the wireless signal is v, the distance l=v (t 1-t 2) between the base station device and the slave device.
S402, the base station equipment determines that the current output power is the preset minimum power under the condition that the distance between the base station equipment and the follow-up equipment is smaller than or equal to a first preset distance.
The preset minimum power is rated minimum output power of the base station equipment.
As a possible implementation manner, the base station device determines whether the distance between the base station device and the slave device determined in the above step S401 is less than or equal to a first preset distance. If yes, the base station equipment determines to transmit wireless signals with rated minimum output power, so that interference to the follow-up equipment is avoided.
It should be noted that the first preset distance may be preset in the base station device by an operator of the communication system, and the first preset distance may be 1 meter, for example.
In some embodiments, taking a base station device as an example of a small base station, the small base station may typically be rated for 10dBm for minimum output power and 27dBm for maximum output power.
For example, when the small base station detects that the distance from the follow-up equipment is less than or equal to 1 meter, the small base station transmits a wireless signal to the follow-up equipment with an output power of 10dBm, so that the follow-up equipment cannot be interfered by the wireless signal transmitted by the base station equipment when providing network coverage for the elevator, and the user experience is ensured.
S403, determining theoretical output power according to the distance when the distance of the base station equipment is larger than a first preset distance.
Wherein the theoretical output power is positively correlated with distance.
As a possible implementation manner, the base station device determines the theoretical output power according to the distance and the preset relation between the distance and the theoretical output power when the distance is greater than the first preset distance.
It should be noted that, in order to ensure that the input power of the slave device is unchanged, as the distance increases, the base station device needs to increase the output power according to the change of the distance, and the preset relationship between the distance and the theoretical output power satisfies the following formula:
P＝P 0 +k 1 ×lgd
wherein P is theoretical output power, P 0 For nominal minimum output power, k, of base station equipment 1 D is the distance between the base station device and the follower device, which is the power adjustment coefficient.
Note that k 1 The power adjustment of the base station equipment can be realized after a plurality of experiments by operation staff of the communication system, so that the requirement of the input power of the follow-up equipment is met, and the method is exemplified by k 1 May be 20.
S404, the base station equipment determines the current output power according to the theoretical output power and the preset maximum power.
The preset maximum power is the rated maximum output power of the base station equipment.
As shown in fig. 5, in the communication method provided in the embodiment of the present application, S404 includes S4041 to S4042.
S4041, the base station device determines that the current output power is the theoretical output power under the condition that the theoretical output power is smaller than or equal to the preset maximum power.
As a possible implementation manner, since the theoretical output power is an output power capable of meeting the input power requirement of the slave device at a corresponding distance, the base station device determines that the current output power is the theoretical output power and transmits the wireless signal to the slave device with the theoretical output power when the theoretical output power is less than or equal to the rated maximum output power of the base station device.
S4042, the base station equipment determines that the current output power is the preset maximum power under the condition that the theoretical output power is larger than the preset maximum power.
As a possible implementation manner, since the theoretical output power is an output power capable of meeting the input power requirement of the follow-up device at a corresponding distance, but the base station device can reach its rated maximum output power at the highest, the base station device sends a wireless signal to the follow-up device at the rated maximum output power under the condition that the theoretical output power is greater than its rated maximum output power, so as to guarantee the input power of the follow-up device as much as possible.
It can be appreciated that, by the communication method, the embodiment of the application can avoid error code generated by saturated signal distortion of the follow-up device due to overhigh output power of the base station device when the base station device is close to the follow-up device, and can ensure the input power of the follow-up device before the base station is adjusted to the rated maximum output power, and the quality of the output wireless signal is stable compared with that of the host device in the prior art.
In one design, FIG. 6 is a flow diagram illustrating a method of communication according to some example embodiments. In some embodiments, the above-described communication methods may be applied to a follower device 22 in a communication system 20 as shown in FIG. 2. Hereinafter, the embodiment of the present application will be described by taking an example in which the communication method is applied to the slave device 22.
As shown in fig. 6, the communication method provided in the embodiment of the present application includes the following S501 to S503.
S501, the follow-up device receives a gain instruction sent by the base station device.
The gain indication is sent by the base station equipment under the condition that the current output power is equal to the preset maximum power.
As one possible implementation, the follower device receives the gain indication sent by the base station device based on the radio path with the base station device.
S502, after receiving the wireless signal sent by the base station equipment, the follow-up equipment responds to the gain instruction to start adjusting the gain of the follow-up equipment.
As a possible implementation manner, after receiving the wireless signal sent by the base station device, the follower device adjusts the intensity of its gain in response to the gain instruction received in the above step S501, so as to provide stable network coverage for the elevator.
It should be noted that, how the following device specifically adjusts its own gain may be described later with reference to the embodiments of the present application, which is not described here again.
S503, the follow-up device processes the received wireless signal based on the adjusted gain.
As a possible implementation, the follower device amplifies the received wireless signal based on the gain adjusted in step S502 described above, so that the user in the elevator can normally use the network service.
It can be understood that in the communication method provided by the embodiment of the application, the follow-up device adjusts the gain of the follow-up device under the condition that the base station device can not increase the output power any more, so that the network coverage provided by the follow-up device for the elevator can meet the network use requirement of the user in the elevator.
In one design, in order to enable the network coverage provided by the following device for the elevator to meet the network usage requirement of the user in the elevator, as shown in fig. 7, the communication method provided by the embodiment of the application further includes S601-S602.
S601, the follow-up device determines the input power of a wireless signal sent by the received base station device.
As a possible implementation method, the follower device detects the receiving antenna, and further determines the input power of the wireless signal received from the base station device.
S602, the follow-up device adjusts the gain of the follow-up device according to the input power.
Wherein the input power is inversely related to the gain of the follower device.
As a possible implementation, the follower device compensates the gain in a linear manner, based on the input power determined in step S601 above, the gain of the follower unit is increased by 1dB each time the input power is reduced by 1dB, so as to guarantee the network coverage provided by the follower device for the elevator.
In one design, when the gain indication sent by the base station device further includes a distance between the base station device and the slave device, in order to enable the slave device to provide network coverage for the elevator to meet network usage requirements of users in the elevator, as shown in fig. 8, the communication method provided in the embodiment of the present application further includes S701-S702.
S701, the follow-up device determines a difference value between the distance and a second preset distance.
The second preset distance is used for indicating the base station equipment to output with a preset maximum power, and the follow-up equipment normally provides network coverage for the elevator under the condition that the gain of the input power of the follow-up equipment is minimum.
As one possible implementation, the follower device calculates a difference between the distance between the base station device and the follower device and the second preset distance based on the distance in the gain indication sent by the base station device and the second preset distance.
S702, the follow-up device adjusts the gain of the follow-up device according to the difference value.
Wherein the difference is positively correlated with the gain of the follower device.
As a possible implementation, the follower device increases the gain of the follower device gradually as the difference increases.
It should be noted that, in order to ensure that the following device can provide normal network coverage for the elevator, as the distance increases, the difference increases, the following device needs to adjust the gain according to the change of the distance, and the relationship between the distance and the gain satisfies the following formula:
G＝G 0 +k 2 ×lg(x+1)
wherein G is the adjusted gain, G 0 K is the rated minimum gain of the follow-up device 2 And x is the difference between the distance between the base station equipment and the follow-up equipment and the second preset distance.
Note that k 2 The gain adjustment of the follow-up equipment can be realized after a plurality of experiments by operation staff of the communication system, so that the network coverage, and the example, k, can be normally provided for the elevator 2 May be 20.
In one design, in order to avoid that the gain of the follower device is adjusted to be too high and cause interference to the receiving antenna, as shown in fig. 9, the communication method provided in the embodiment of the application further includes S801-S802.
S801, the follow-up device determines the current isolation of the follow-up device.
As one possible implementation manner, the following device determines a ratio of a wireless signal sent by a transmitting antenna and received by a receiving antenna of the following device to a wireless signal sent by the transmitting antenna, where the ratio is the current isolation.
S802, under the condition that the current isolation degree is smaller than or equal to the preset isolation degree, the follow-up equipment stops adjusting the gain of the follow-up equipment.
As one possible implementation, the follower device determines a magnitude relation between the current isolation and the preset isolation, and stops adjusting the gain of the follower device if the current isolation is less than or equal to the preset isolation.
The preset isolation may be preset in the slave device by an operator of the communication system. Illustratively, based on the hardware attribute of the follower device, determining an initial isolation of the follower device when amplifying the wireless signal with a minimum gain, wherein the preset isolation is the initial isolation of-15 dB, that is, after the isolation of the follower device is reduced by 15dB, adjusting the gain of the follower device is stopped.
For example, as shown in fig. 10, a curve of the gain of the slave device according to the distance between the base station device and the slave device may be shown, where in the first stage, the slave unit maintains a nominal minimum gain when the distance is less than or equal to the second preset distance; in the second stage, under the condition that the distance is larger than the second preset distance, the follow-up unit increases the gain along with the increase of the distance until the third stage, after the isolation degree of the follow-up device is equal to the preset isolation degree, the follow-up device stops adjusting the gain of the follow-up device, the base station device transmits a wireless signal with rated maximum output power in the communication system, and the follow-up device amplifies the wireless signal with the gain capable of guaranteeing that the isolation degree meets the requirement and provides network coverage for an elevator.
It can be understood that, as the gain of the following device increases, the power of the wireless signal transmitted by the following device increases, the receiving antenna is more easily interfered by the transmitting antenna, and the wireless signal may be distorted, so after the isolation of the following unit reaches the preset isolation, the adjustment of the gain is stopped, and the stability of the network coverage provided by the following device for the elevator can be ensured.
In some embodiments, if the elevator is ascending from the bottom, the follower device first decreases the gain to a minimum based on the received increase in input power of the wireless signal sent by the base station device. Further, as the distance is reduced, the base station device reduces the output power according to the distance between the base station device and the follow-up device, so that interference to the follow-up device is avoided, and network coverage of an elevator is affected.
