firstly, under the NBIOT network coverage environment, the input end of the energy-saving control device 2 is accessed to a 4-48V power supply 24 of a base station, and after the energy-saving control device 2 is electrified, a GPIO port connected with a processor 22 and an access module boot pin of the Internet of things card 21 outputs high or low level for 3 seconds to complete the boot of the Internet of things card 21; the serial port of the processor 22 sends an internet of things 1 registration and internet of things 1 access instruction to the internet of things card 21, after receiving the instruction, the internet of things card 21 reports the internet of things 1 to complete network registration and internet of things 1 access operation, each internet of things card 21 names a cell identifier of an RRU when the internet of things 1 names equipment, so that the IMEI number of the internet of things card 21 in each energy-saving control device 2 corresponds to the cell identifier of the RRU of the base station 4 one by one; after the energy-saving control device 2 is accessed to the internet of things 1, the processor 22 controls the first switch to be conducted, so that the RRU is in a power-on working state when the energy-saving control device 2 is started; after the processor 22 completes the above operations, the hall sensor is sleeved on the RRU power supply cable, and the current value of the hall element is collected through the ADC; the temperature sensor is placed in the environment by using the temperature sensor, and the value of the temperature sensor is collected by the ADC. At this time, the energy-saving control device 2 is in a normal working state, and the whole energy-saving control system based on the internet of things 1 is also in a normal working state.
Based on the base station 4 energy-saving control system based on the internet of things 1 shown in fig. 7, as shown in fig. 8, the base station 4 energy-saving control method based on the internet of things 1 includes the following steps:
step S201: the Internet of things 1 acquires the number of users and the number of services of a base station 4;
step S202: the Internet of things 1 judges whether the number of users is larger than a first preset number or not and judges whether the number of services is larger than a second preset number or not;
when the number of users is less than or equal to the first preset number and the number of services is less than or equal to the second preset number, the internet of things 1 executes step S203,
step S203: judging whether the base station 4 and the RRU are in a disconnected state;
when the base station 4 and the RRU are disconnected, the internet of things 1 does not perform any action, and the whole control process continues to acquire the number of users and the number of services of the base station 4, that is, step S201.
When the base station 4 and the RRU are in a connected state, the internet of things 1 performs step S204, that is
Step S204: the internet of things 1 sends a first instruction, wherein the first instruction is used for indicating that the connection between the base station 4 and the remote radio unit 3 is disconnected;
step S205: the internet of things card 21 receives a first instruction sent by the internet of things 1 and transmits the first instruction to the processor 22;
step S206: the processor 22 converts the first instruction into a first instruction signal and sends the first instruction signal to the first switch unit 23;
step S207: the first switch unit 23 automatically disconnects according to the first instruction signal, that is, the base station 4 is disconnected from the RRU, so that the RRU is disconnected when the number of users is small and the number of services is small, thereby saving power.
When the number of users is greater than the first preset number or the number of services is greater than the second preset number, and the internet of things 1 issues an instruction, it still needs to determine whether the current RRU is disconnected from the base station 4, that is, the internet of things 1 executes step S203,
when step S203 determines that the RRU is in a connected state with the base station 4, the internet of things 1 does not perform any step, and the whole control process continues to acquire the number of users and the number of services of the base station 4, that is, step S201.
When step S203 determines that the current RRU is disconnected from the base station 4, the internet of things 1 performs step S208, that is, step S208 is executed
Step S208: the Internet of things 1 sends a second instruction, wherein the second instruction is used for indicating that the connection between the base station 4 and the remote radio unit 3 is conducted;
step S209: the internet of things card 21 receives a second instruction sent by the internet of things 1 and transmits the second instruction to the processor 22;
step S2091: the processor 22 converts the second instruction into a second instruction signal and sends the second instruction signal to the first switch unit 23;
step S2092: the first switch unit 23 automatically disconnects according to the second instruction signal, that is, the base station 4 is connected to the RRU, so that the RRU is reconnected to the base station 4 when the number of users or the number of services is large.
When the connection state of the base station 4 and the RRU is changed, the processor 22 sends the connection state of the base station 4 and the RRU to the internet of things card 21, the internet of things card 21 sends the connection state of the base station 4 and the RRU to the internet of things 1, and the internet of things 1 stores and displays the connection state for a worker to query the connection state of the base station 4 and the RRU constantly.
The whole energy-saving control system based on the internet of things 1 executes the steps S201 to S2092, and at the same time, executes the following steps:
step S301: the temperature sensor acquires the ambient temperature of the base station 4, and the Hall sensor acquires the current of the base station 4;
step S302: the processor 22 transmits the ambient temperature and the current of the base station 4 to the internet of things card 21;
optionally, the processor 22 reports the current and temperature values to the internet of things 1 once every N seconds, the internet of things 1 records and stores time and corresponding current and temperature values, and since an IP link of a module of the internet of things 1 is released within 2 minutes, an instruction cannot be issued in real time after the release, the value of N should be less than 120, and it is ensured that there is an operation of reporting the current and temperature values to the internet of things 1 by the processor 22 within 2 minutes.
Step S303: the Internet of things card 21 transmits the ambient temperature and the current of the base station 4 to the Internet of things 1; the Internet of things 1 can display current and ambient temperature, and workers can know the ambient temperature and the current in real time.
Step S304: the internet of things 1 judges whether the current is abnormal according to the current, and when the current is abnormal, for example, the current suddenly becomes zero or cannot receive the current suddenly.
When the current is abnormal, the internet of things 1 performs step S305, that is
Step S305: the internet of things 1 sends a command of connecting or disconnecting the base station 4 and the radio remote unit 3 according to the number of users and the first preset number, the number of services and the second preset number, that is, when the current is abnormal, it is very likely that the first switch unit 23 is abnormal, at this time, the first switch unit 23 has failed, and then whether to disconnect or connect the base station 4 and the RRU is needed, and also according to the relationship between the number of users and the first preset number, and the number of services and the second preset number.
When the number of users is less than or equal to a first preset number and the number of services is less than or equal to a second preset number, the internet of things 1 may issue a first command, and thereafter, the whole energy saving control method based on the internet of things 1 may include: the second switching unit 25 is manually controlled to open according to the first command.
Alternatively, the internet of things 1 transmits the first command to the energy saving control unit, and the energy saving control unit performs the disconnection of the second switching unit 25.
Similarly, when the number of users is greater than the first preset number or the number of services is greater than the second preset number, the internet of things 1 may issue a second command, and thereafter, the whole energy saving control method based on the internet of things 1 may include: according to the second command, the second switching unit 25 is manually controlled to be turned on.
Alternatively, the internet of things 1 transmits the second command to the energy saving control unit, and the energy saving control unit performs the disconnection of the second switching unit 25.
Whether the first switch unit 23 or the second switch unit 25 turns on or off the connection between the base station 4 and the RUU, the processor 22 transmits the connection state between the base station 4 and the RRU to the platform of the internet of things 1, that is, the processor 22 executes step S306, that is, the processor 22 performs step S
Step S306: the processor 22 transmits the connection status of the base station 4 and the RRU to the internet of things 1.
According to the energy-saving control system and method based on the Internet of things 1, the first switch and the second switch are connected in parallel, and when the first switch is abnormal, the second switch can be connected or disconnected between the base station 4 and the RRU.

When the internet of things 1 has a good effective monitoring model, the internet of things 1 can also pre-judge whether to select disconnection or connection of the RRU3 and the base station 4 according to the current of the base station 4, at this time, whether to select disconnection or connection of the RRU3 and the base station 4 can be pre-judged from the number of users and the number of services of the base station 4 and the current of the base station 4 at the same time, no matter whether any one mode fails, the other mode can still disconnect or connect the RRU3 and the base station 4, so that the labor cost is further saved, the risk probability of positioning errors is reduced, electricity is saved, the service with higher purchase cost can be avoided, and the cost is reduced.
