[0015] Figure 2 The schematic diagram of the energy-saving system architecture of the base station in the tunnel provided by the embodiment of the present application is shown as follows: Figure 2 As shown, the system consists of a tunnel environment base station power supply remote control device, a base station power supply (system), a tunnel environment base station power supply remote control management platform, base station equipment (i.e., base station master control equipment, base station radio frequency equipment, base station transmission equipment), etc. The tunnel environment base station power supply remote control device is connected to the base station power supply and the base station master control. The base station power supply is provided with AC power by the tunnel environment base station power supply remote control device, and the base station equipment (i.e., base station master control equipment, base station radio frequency equipment, base station transmission equipment) is provided with uninterrupted DC-48V power by the base station power supply.

[0016] The base station power supply is equipped with an intelligent output DC-48V power distribution unit. The DC-48V power distribution output branch can be set for users, zones, and sectors separately. The base station main equipment such as the base station master control equipment BBU, base station radio frequency equipment RRU / AAU, and base station transmission equipment PTN are powered by the power output branch. It is set to supply power to a single user's equipment separately. It can be set to supply power to equipment for multiple users, multiple zones, and multiple sectors.

[0017] The remote control equipment for power supply of base stations in tunnel environment consists of multiple plug-and-play control modules, power distribution units, metering modules, communication modules and monitoring modules, etc. It has the functions of timing on-off control, time-sharing on-off control, user-by-user on-off control, branch on-off control and remote control management. The remote control equipment for power supply of base stations supports branch and household metering functions, and can realize metering and energy-saving control of different branch equipment, users (telecom operators), partitions (such as tunnels), intelligent capacity setting, etc. through different configurations; it supports multi-circuit full-electric parameter measurement, DI / DO input and output, NTC temperature measurement, temperature and humidity measurement, dust, carbon dioxide concentration, visibility and other non-electrical parameter monitoring. It can communicate with the base station master through wireless or wired communication, and obtain the real-time sleep and wake-up strategy information of base station equipment such as base station master equipment, radio frequency equipment gateway, and transmission equipment; it can communicate with the base station power supply through wireless or wired communication, and transmit the real-time sleep and wake-up strategy information of the base station equipment to the base station power supply.

[0018] In an embodiment of the present application, in scenarios with obvious tidal phenomena, such as during nighttime train suspensions and after the operator's equipment is shut down in layers, the spare optical cores can be used to connect to the FSU or gateway in the nearest distribution room, so that the platform can cancel the timed opening and closing or remote closing in an emergency, thereby solving the problem of weak wireless signals and inability to communicate.

[0019] The tunnel environment base station power supply remote control management platform can obtain and acquire the real-time sleep and wake-up strategy information, traffic data and its information of base station equipment such as base station master equipment, radio frequency equipment gateway, and transmission equipment through the openAPI interface, and transmit the real-time sleep and wake-up strategy information, traffic data and its information of the base station equipment to the tunnel environment base station power supply remote control equipment. The base station power supply remote control equipment forms a real-time sleep and wake-up control strategy for the base station equipment based on the real-time sleep and wake-up strategy information, traffic data and its information, train timetable and other data after processing by algorithms such as traffic change rate, real-time train timetable, sleep classification, etc., and then sends the control strategy to the base station power supply, thereby controlling the base station power supply to perform graded energy-saving sleep and wake-up control.

[0020] Step 104: Determine the dormancy energy saving level of the base station power supply in the tunnel environment according to the train schedule and the change rate of the historical traffic volume.

[0021] In an embodiment of the present application, after obtaining the real-time train schedule and obtaining the change rate of historical traffic volume based on the historical traffic volume, the sleep energy saving level of the base station power supply in the tunnel environment can be determined based on the train schedule and the change rate of historical traffic volume.

[0022] In one implementation, the sleep energy saving level of the base station power supply in the tunnel environment is determined based on the train schedule and the rate of change of the historical traffic volume, including: determining the idle period in the tunnel during the sleep period when the tunnel is not open to traffic based on the train schedule; merging the two adjacent idle periods into a continuous idle period when the time interval between two adjacent idle periods meets an interval threshold; and determining that the sleep level of the base station power supply is a first-level sleep level during the idle period and the continuous idle period.

[0023] In the embodiment of the present application, the idle time period in the tunnel during the sleep period when no trains pass can be determined according to the train schedule. For example, the sleep period can be from 23:30 to 4:30 the next day, and the train schedule of the sleep period is obtained, and the time period when no trains pass is determined as the idle time period, for example, idle time period 1 is from 23:50 to 0:20 the next day, idle time period 2: 0:25 the next day to 0:37 the next day, idle time period 3: 0:50 the next day to 1:12 the next day, idle time period 4: 1:18 the next day to 2:20 the next day, etc.

[0024] Calculate the time interval between every two adjacent idle periods, for example, the time interval between idle period 1 and idle period 2 is 5 minutes, the time interval between idle period 2 and idle period 3 is 13 minutes, and the time interval between idle period 3 and idle period 4 is 6 minutes. Merge the idle periods whose time intervals meet the interval threshold. For example, if the interval threshold can be 10 minutes, then idle period 1 can be merged with idle period 2, and idle period 3 can be merged with idle period 4. Then, the sleep level of the base station power supply in the idle period and the continuous idle period can be determined as the first sleep level, that is, 23:50 to 0:37 the next day and 0:50 to 2:20 the next day are the first sleep energy-saving periods, and the sleep level of the base station power supply is the first sleep level.

[0025] In one implementation, the sleep energy saving level of the base station power supply in the tunnel environment is determined based on the train schedule and the rate of change of the historical traffic volume, including: dividing the non-sleep period into multiple sub-periods at preset intervals; calculating the rate of change of traffic volume in each sub-period and the average traffic volume in each sub-period based on the historical traffic volume; determining a target sub-period from each sub-period in which the average traffic volume is less than a first threshold and the rate of change of traffic volume is less than a second threshold; and determining that within the target sub-period, the sleep energy saving level of the base station power supply is a secondary sleep level.

[0026] In the embodiment of the present application, the non-sleep period can be divided into multiple sub-periods at preset intervals. For example, the non-sleep period can be divided into sub-periods every 30 minutes, and then the traffic volume change rate of each sub-period and the average traffic volume of each sub-period are calculated based on the historical traffic volume. Specifically, the traffic volume change rate of each sub-period is The calculation is performed according to the following method:

[0027] in, It's in time The volume of telephone traffic, is the seasonal correction factor, is the holiday correction factor.

[0028] Seasonal correction factor The calculation is to calculate the average traffic volume in each season of the year, and take the ratio of the average traffic volume to the total average traffic volume as the seasonal correction coefficient for the sub-period.

[0029] Holiday correction factor The calculation is to collect the traffic data of the period during historical holidays, calculate the ratio of the average traffic volume during holidays to the average traffic volume during non-holidays, and use it as the holiday correction coefficient for this sub-period.

[0030] After obtaining the change rate of the traffic volume in each sub-period and the average traffic volume in each sub-period, the average traffic volume in each sub-period can be used to calculate the traffic volume of each sub-period. and traffic change rate , a target sub-period is determined from the multiple sub-periods, and within the target sub-period, the sleep energy saving level of the base station power supply is the second-level sleep level.

[0031] Specifically, the determination of the target sub-period must meet the following two conditions at the same time: the average traffic volume of the sub-period Less than the first threshold; the traffic change rate of the sub-period The first threshold and the second threshold can be set according to actual needs.

[0032] Step 106: hierarchically hibernate the base station power supply according to the hibernation energy-saving level of the base station power supply.

[0033] Specifically, after the dormancy energy-saving level of the base station power supply is determined, the base station power supply can be hibernated in stages according to the dormancy energy-saving level of the base station power supply.

[0034] In one implementation, the base station power supply is graded into sleep mode according to the sleep energy saving level of the base station power supply, including: when the sleep level of the base station power supply is the first sleep level, controlling the base station power supply DC output power supply branch to shut down the corresponding base station device when the base station device is in sleep state.

[0035] Specifically, when the sleep energy saving level of the base station power supply is the first sleep level, the base station power supply DC output power supply branch is controlled to shut down the corresponding base station equipment when the base station equipment is in sleep state.

[0036] In one implementation, the base station power supply is hibernated in stages according to the sleep energy saving level of the base station power supply, including: when the sleep level of the base station power supply is the second-level sleep level, retaining the power supply of a radio frequency device in the tunnel field sector, hibernating or shutting off the power supply of other sector and regional radio frequency devices, and increasing the overcurrent protection rating of the DC output power supply shunt by a preset multiple.

[0037] Specifically, when the sleep energy saving level of the base station power supply is the second-level sleep level, in order to retain the power supply of a RF device in the sector entering the tunnel field, other sectors and regional RF devices are put into sleep or shut down. The base station power supply DC output power supply branch corresponding to the sleep base station RF device, the base station power supply will obtain the current value of the base station RF device in the sleep state for a certain period of time, and take the maximum value in the list. The base station power supply sets the overcurrent protection rated value of the DC output power supply branch to a preset multiple of the maximum current value of the base station RF device in the sleep state. For example, the preset multiple can be 2 to 4 times. If the device current value in the sleep state is 2 amperes, the overcurrent protection rated value of the DC output power supply branch is set to 4A to 8A.

[0038] The control method for power supply of a base station provided in an embodiment of the present application obtains the train timetable of trains running in a tunnel environment and the historical traffic volume of the base station in the tunnel environment; determines the sleep energy saving level of the base station power supply in the tunnel environment according to the change rate of the train timetable and the historical traffic volume; and hierarchically hibernates the base station power supply according to the sleep energy saving level of the base station power supply. In a tunnel scenario, some systems can be shut down on a timed basis during idle periods when trains are out of service to reduce energy waste. The system cooperates with the radio frequency equipment to obtain information such as low traffic volume and train passing timetable, and the radio frequency equipment intelligently hibernates, thereby collaboratively realizing hierarchical energy-saving control, filling the gap in intelligent energy-saving control technology for base stations in tunnel environments, saving energy and reducing carbon emissions, and significantly reducing energy consumption and resource waste.

[0039] In one implementation, after performing hierarchical sleep on the base station power supply according to the sleep energy saving level of the base station power supply, it also includes: obtaining the real-time traffic volume of the base station in the tunnel environment at preset time intervals; calculating the predicted traffic volume based on the real-time traffic volume and the real-time traffic volume change rate in the time period to which the real-time traffic volume belongs; and waking up the base station power supply in the first sleep level or the second sleep level when the predicted traffic volume is greater than a third threshold.

[0040] In the embodiment of the present application, the real-time traffic volume of the base station in the tunnel environment can be obtained at intervals of a preset time period. , combined with the traffic change rate Get predicted traffic volume , when predicting the traffic volume Specifically, in actual application scenarios, when performing hierarchical sleep operations corresponding to the second-level sleep energy saving level, in the sleep state, the real-time traffic volume is obtained at intervals of a preset time period, such as 1 minute. , combined with the traffic change rate Calculate forecasted traffic volume :

[0041] Among them, the traffic change rate is the rate of change of the time period to which the real-time traffic belongs. The calculated predicted traffic volume If the third threshold is exceeded, a wake-up operation needs to be performed immediately, and the third threshold can be set according to actual needs.

[0042] In one implementation, the waking-up operation of a base station power supply that is in a first-level sleep level or a second-level sleep level includes: when the base station power supply is in a first-level sleep level, at least a first preset time before the end of sleep, controlling the base station power supply DC output power supply shunt to be connected to restore power supply to the base station equipment; when the base station power supply is in a second-level sleep level, controlling the base station power supply DC output power supply shunt to be connected to restore power supply to the base station equipment, and restoring the overcurrent protection rated value of the DC output power supply shunt to a non-initial setting value.

[0043] The specific wake-up operation for the second-level sleep energy saving level is: the base station power supply DC output power supply branch is connected to restore the power supply of the base station equipment, and the overcurrent protection rating of its DC output power supply branch is restored to the initial setting value. When performing the hierarchical sleep operation corresponding to the first-level sleep energy saving level, the wake-up strategy is: the base station power supply DC output power supply branch is connected to restore the power supply of the base station equipment at least the first time in advance of the sleep end time, for example, the first time can be 10 minutes, and the equipment can be carried out according to actual needs.

[0044] In the application embodiment, the tunnel environment power supply remote control system interacts with sleep mechanisms such as the RF device gateway, and uses a hierarchical energy-saving strategy to obtain real-time traffic information, RF device sleep and wake-up strategies, train arrival time information, etc. The tunnel environment power supply remote control system can perform sleep and wake-up energy-saving operations in real time, achieve refined energy-saving control, and maximize energy saving and carbon reduction.
