The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses a control method for long-distance intelligent differentiation direct current output standby power endurance for a 5G base station, which can be realized by loading and executing a calculation program for realizing the method through a computer and the like.
Referring to 1,5G, the method for controlling the remote intelligent differentiated dc output standby power endurance for the base station comprises the following steps:
s101, KPI information of a base station and state information of a power supply group are obtained.
In the present embodiment, the KPI of the base station mainly includes a load capacity indicator, more specifically, the number of users in the service class, so as to cooperate with the following content.
Three power supply groups are provided in the application, wherein one power supply group is a municipal power grid; one is an oil engine or other generator set; one is a standby power supply, namely a storage battery pack. The state information of the power supply group comprises at least voltage and current information, and the storage battery group comprises at least electric quantity information.
S102, determining the number of access users of each sub-user based on the KPI information of the base station, generating a communication log of each sub-user by combining time parameters, and binding a preset serial number of the base station.
Wherein, the sub-users, such as operators of Unicom, mobile, telecom, etc.; the number of sub-users, that is, the number of users of each operator within the range of the base station; the data can be acquired by butting an operator platform, but in consideration of privacy of users, platform interfaces, information safety and the like, the base station KPI information acquisition is preferably performed, and the effect is better on the premise that the base station local system is applied in the method.
The serial number at least includes a base station number and an area identification number where the base station is located, for example: the serial number of the Nth base station in the area A is A-N.
It can be understood that the communication log is not only applied to the current base station, but also uploaded to a regional management cloud platform for use, and therefore, a serial number needs to be added for distinguishing the communication log.
The management cloud platform is configured to:
identifying base stations in the same area (such as an administrative area) according to the serial numbers, and obtaining communication distribution of the base stations in the same area according to communication log statistics; the relevant data can be used for reference in the subsequent equipment upgrading of the base station.
And S103, determining the current power supply mode of the base station to be one or more of mains power supply, power supply of a power generation set and power supply of a storage battery set based on the state information of the power supply set.
It can be understood that, for example, the mains voltage and current are 0, and the battery pack outputs the operating voltage, i.e., the mains is powered off and the battery pack is powered on.
And S104, if the current power supply mode of the base station does not have commercial power supply, calling the communication logs of all sub-users to execute differentiated power supply logic.
It can be understood that the method is mainly applied to a scene of starting the standby power supply and is set for improving the endurance of the standby power supply, and therefore, in the embodiment, only the abnormal power supply of the commercial power and other power supply modes are used for explanation.
Referring to fig. 2, differentiated power-on logic includes:
s201, judging whether the current access user number of the sub-users is smaller than a preset low access threshold value; if yes, recording the score a in a preset score; if not, the process is ended.
