[0052] Each of the steps will be described in further detail below.
[0053] In step S210, the communication connection of the electronic price sign and the base station is established.
[0054] Specifically, the electronic price sign and the base station constitute an electronic price sign communication system. The base station consists of the gateway and the main processor, and the number of gateways can be flexibly configured according to their own protocol system. The main control refers to the main processor inside the base station, with data concurrency processing capability, RF module (gateway) inside the base station, with the ability to communicate with 2.4G private protocols and electronic prices.

In the present embodiment, the communication parameters are signal strength parameters, and it is necessary to explain that the distance from the electronic price sign and the base station in different regions is different, which leads to different signal strength parameters received by different electronics prices. The intensity of the communication signal is relative to the power, the propagation distance of the high power signal is long, so that when the electronic vag is closer to the base station, if it is still transmitted with a larger power, It will cause a certain amount of power consumption. In the present embodiment, step S220 can be performed by the following steps:
[0057] Step S2201, the acceptance signal is acquired, wherein the reception signal is a communication signal sent to the electron-free signage;
[0058] In step S2202, the signal strength parameters of the received signal is parsed according to the reception signal.
[0059] Through the above steps, the electronic price swab can be evaluated from the distance between the base station based on the signal strength transmitted from the base station.

Step S230 can be determined from the corresponding signal transmission power from the corresponding relational table according to the communication parameters. In the present embodiment, the communication parameters are signal strength parameters, and the corresponding relationship between the different signal intensity parameters in the correspondence table is stored in the corresponding relationship. When the electronic price sign determines the range in which the signal strength parameter is received, the corresponding signal transmission power is found through the correspondence table.

[0067] Step S2403, the base signal transmit power is adjusted to obtain the final signal transmission power according to the operating state to obtain the final signal transmission power;
[0068] In step S2404, the signal transmission of the electronic price sign is controlled in accordance with the final signal transmission power.
[0069] In step S2401, the base signal transmit power refers to the basic value of the power adjustment according to the operating state of the electronic price sign. In the present embodiment, the basic signal transmit power is a signal transmit power determined according to the signal strength parameter. In step S2402, the operating state includes at least one of the following: registration, standby, and push map.
[0070] In the present embodiment, in step S2403 can be performed by the following steps:
[0071] In step S24031, the corresponding power adjustment strategy is determined according to the working state;
[0072] In step S24032, the base signal transmit power is adjusted according to the power adjustment policy to obtain the final signal transmission power.
[0073] Among them, the power adjustment strategy refers to the adjustment method of determining the basis transmission power based on different working states. In the present embodiment, the operating state is pusc, and step S24032 can be performed by the following steps:
[0074] Pushing with the preliminary signal transmission power, wherein the preliminary signal transmit power is the signal transmission power obtained by the basic signal transmission power or the first adjustment of the base signal transmission power;
[0075] Detect whether the pusher is successful;
[0076] When the pusher is successful, the transmit power is transmitted in the final signal transmission power at the time of success.
[0077] When the pusher fails, the preset adjustment amplitude is increased according to the preset adjustment, until the pusher is successful.
[0078] Specifically, the dynamic adjustment power mechanism is in addition to the signal intensity range, and the different power is called, and the operation of the pricing sign is also dynamically adjusted transmit power, ensuring the function, and does not result in unnecessary excessive exhaustion power waste power. For example, in the pusher process, join push Figure one The number of times is unsuccessful, which can increase the transmit power to the maximum transmit power or increase the power in a certain power step, and then return the default transmit power after the push is successful.
[0079] Through the above embodiment, after establishing the communication connection of the electronic bid and the base station, the communication parameters of the electronic value to the base station are determined, and the corresponding signal transmission of the electronic price sign is determined according to the communication parameter. The power is transmitted according to the signal transmission power to control the signal transmission of the electronic pricing, so that the electronic price swab can adjust the signal transmission power according to the distance from the base station, while determining the final signal transmission power, further Determine the working state of the electronic price sign, determine the different power adjustment strategies according to different working conditions, so that the electronic bid is determined according to the actual situation determines the corresponding signal transmission power, and the stable communication is reduced, reducing the transmission power, reducing power consumption, improvement The life of the price is reduced to maintain the maintenance cost.
