Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to 4, the structure of the intelligent control energy storage system of the 5G communication device is schematically illustrated. The intelligent control energy storage system of the 5G communication equipment is electrically connected with the commercial power, the 5G communication equipment and the air conditioner lighting. Commercial power is usually referred to as mains frequency Alternating Current (AC) and is characterized by three common quantities of AC: voltage, current and frequency, 5G machine room generally introduces three-phase 380V and 50HZ commercial power as power supply. The 5G communication equipment is core equipment of a 5G network, provides wireless coverage and realizes wireless signal transmission between a wired communication network and a wireless terminal. The air conditioner lighting is a device for adjusting temperature and lighting installed in a 5G machine room, which is a prior art and will not be described in detail herein. The intelligent control energy storage system of the 5G communication equipment comprises an initialization setting module 10, a commercial power on-off control module 20, a data acquisition and conversion module 30, an instruction output module 40, an energy storage control module 50 and an energy storage battery 60 for providing power for the 5G communication equipment and air conditioner illumination. It is conceivable that the intelligent control energy storage system of the 5G communication device further includes other hardware structures and functional modules, such as a mounting module, an electrical connection component, a central processing unit, etc., which are well known to those skilled in the art and will not be described in detail herein.
The initialization setting module 10 is configured to initially set a timing parameter for performing peak clipping and valley filling. The peak clipping and valley filling is a common technology for power application, and is a measure for adjusting power utilization load, and the power utilization time of various users is reasonably and programmatically arranged and organized according to the power utilization rules of different users so as to reduce the load peak, fill the load valley, reduce the load peak and valley difference of a power grid and balance power generation and utilization. Because the electric quantity generated by the power generation enterprises is difficult to store, if the electric quantity cannot be used in time, the waste of resources can be caused. The parameter set by the initialization setting module 10 to perform peak clipping and valley filling may be time or voltage. The time can be set by the user at will, for example, at 8 o 'clock to 22 o' clock, the energy storage battery 60 supplies power to the whole 5G communication equipment and air conditioner lighting, and at 22 o 'clock to 8 o' clock of the next day, the commercial power supplies power and charges the energy storage battery 60, thereby achieving the purpose of peak clipping and valley filling. Or the voltage is used as a reference parameter for peak clipping and valley filling, that is, whether the electric quantity of the energy storage battery 60 is sufficient is judged by collecting the output voltage of the energy storage battery 60, if the electric quantity is insufficient, the charging is carried out, and if the electric quantity is sufficient, the discharging is carried out, so that the purpose of peak clipping and valley filling is achieved. The time parameter is typically used to adjust the peak to valley power. In this embodiment, the timing parameter for executing peak clipping and valley filling set by the initialization setting module 10 is a time parameter, and of course, the specific execution time may be arbitrarily set by the user, that is, the time is an arbitrary time period in one day. In addition, in actual use, the parameter setting of the initialization setting module 10 is performed by the instruction output module 40, which will be described in detail below in conjunction with the instruction output module 40.
The commercial power on-off control module 20 controls the whole 5G communication device and the commercial power to be connected and disconnected according to the output instruction of the instruction output module 40 or the working state of the commercial power, that is, when the commercial power is in a normal state, the commercial power on-off control module 20 is in a normally closed state, and when the commercial power is in a fault or disconnected state and the commercial power needs to be turned off, for example, when the energy storage battery 60 starts to discharge, the commercial power on-off control module 20 is tripped, so that the commercial power is electrically connected with the 5G communication device. The utility power on-off control module 20 includes a processing unit 21, an on-off unit 22, an information processing module 23, and a potential sensor 24. The processing unit 21 is configured to receive the instruction and the data from the data acquisition and conversion module 30 and the instruction output module 40, perform logic operation, control, communication, feedback detection, and the like on the instruction and the data, and transmit the processed instruction to the on-off unit 22. The on-off unit 22 may be a contactor or a circuit breaker, and when the commercial power is in a normal state, the contactor is in a normally closed state, and when the commercial power is failed or disconnected and the commercial power needs to be turned off, such as when the energy storage battery 60 starts to discharge, the contactor is tripped, so that the commercial power is turned off and the electrical connection of the 5G communication device is turned off. The information processing module 23 is configured to connect the processing unit 21 and the instruction output module 40 to implement data replacement between the processing unit 21 and the instruction output module 40. The information processing module 23 may be an RS485 module, and is responsible for information interaction. The potential sensor 24 may be a hall sensor, which is used to detect whether the utility power is normal. The detection of the utility power by the electric potential sensor 24 can know whether the utility power is normal, and if the utility power is abnormal, the electric potential sensor 24 can detect and transmit the detection result back to the processing unit 21. The processing unit 21 then controls the switching unit 22 to switch off the mains.
The data acquisition and conversion module 30 is configured to acquire the operating states of the energy storage battery 60 and the commercial power on-off control module 20 and the parameters of the commercial power. The data collection conversion module 30 may be an edge gateway. The edge gateway itself is a prior art, and includes a central processing unit, a memory, a time controller, various interface circuits, an sim card slot, and the like, which can complete the work of collecting data, uploading data, calculating data, issuing commands, and the like. The data acquisition and conversion module 30 can convert the instruction from the instruction output module 40 into a data format suitable for the commercial power on-off control module 20 to recognize, and also convert the data formats from the commercial power on-off control module 20 and the energy storage control module 50 into a data format recognizable by the instruction output module 40. The data acquisition and conversion module 30 further acquires the current and voltage of the utility power acquired by the potential sensor 24 and the working state of the on-off unit 22, so that the data of the utility power acquired by the data acquisition and conversion module 30 and the data of the on-off unit 22 are transmitted back to the instruction output module 40, and the instruction output module 40 can make a correct instruction. In actual use, the edge gateway and the hardware where the commercial power on-off control module 20 is located can be combined into one to form an intelligent module, so that the concentration degree is improved, and the cost is reduced. The physical schematic diagram of the hardware is shown in fig. 2.
The instruction output module 40 may receive an instruction from a customer to control the working states of the energy storage battery 60 and the commercial power, or may receive information from the commercial power and the energy storage battery 60 and present the information to the customer, and then the customer determines the working state of the entire 5G communication device. Specifically, the instruction output module 40 is configured to output a peak clipping and valley filling instruction according to the parameter set by the initialization setting module 10 and output a charge and discharge instruction or a stop instruction of the energy storage battery 60 according to the data acquired by the data acquisition and conversion module 30. The command output module 40 may be a cloud platform, which may be used for data display, monitoring of an energy storage system, alarm processing, work order issuing, command issuing, electric charge settlement, load prediction, and the like, but is a prior art and will not be described in detail herein. Data exchange between the cloud platform and the data acquisition and conversion module 30 can also be transmitted through 5G, so that efficiency is improved.
The energy storage control module 50 is electrically connected between the utility power and the energy storage battery 60 and includes an energy storage converter 51 and a battery charging and discharging control unit 52. The energy storage converter 51, i.e. a PCS system, is electrically connected between the commercial power and the energy storage battery for switching between direct current and alternating current, i.e. when charging, the alternating current of the commercial power is converted into direct current to charge the energy storage battery 60, and when discharging, the direct current of the energy storage battery 60 is converted into alternating current to provide power for the 5G communication equipment and the air conditioner lighting. The battery charging and discharging control unit 52 may be a circuit breaker, and is configured to control on and off of the energy storage battery 60 and the 5G communication device and the air conditioner lighting according to the instruction of the instruction output module 40, so as to charge and discharge the energy storage battery 60.
The energy storage battery 60 may be a long-cycle lithium iron phosphate battery, which may meet 15 years of operation. It is of course conceivable that other batteries could be used, such as lead acid batteries, but that have a shorter life and reduced capital gain compared to lithium iron phosphate batteries. The energy storage battery 60 can be charged or discharged, so that the purpose of peak clipping and valley filling can be achieved. In fig. 2, the energy storage control module 50 and the energy storage battery 60 are shown as being combined into one energy storage system. In addition, when the energy storage battery 60 supplies power to the air conditioner lighting and 5G communication equipment, the energy storage converter 51, i.e. the PCS system, may be used to switch between dc and ac, as shown in fig. 2. Of course, as shown in the schematic diagram of fig. 4, the PCS system in fig. 2 may be changed to a unidirectional AC/DC system, so that the AC/DC side only supplies power to the energy storage battery 60, and a DC/DC system is added to the DC side of the energy storage battery 60, and only supplies power to the 5G communication device, that is, when the energy storage system needs to supply power to the 5G communication device, the DC/DC system is turned on, and the energy storage battery 60 supplies power to the 5G communication device, that is, the energy storage battery 60 is not inverted to an AC to supply power to the air conditioner lighting, so that the circuit is simple, and the stability of the whole system is ensured.
The intelligent control energy storage system of the 5G communication device may further include a positioning module 70. The positioning module 70 is used for positioning the position of the base station. When the 5G communication equipment is located remotely and widely, the positioning module 70 can precisely position the base station, so that the operation and maintenance personnel can conveniently locate the base station. The positioning module 70 is to arrange a GPS module in the data acquisition and conversion module 30 for positioning. Since the data acquisition and conversion module 30 usually has a central processing unit to process the data collection and conversion, the GPS module can be loaded through the interface circuit.
When the commercial power normally operates and does not need to perform peak clipping and valley filling during operation, the instruction output module 40 sends an instruction to the commercial power on-off control module 20 and the energy storage control module 50 through the data acquisition and conversion module 30, so that the commercial power is switched on through the on-off unit 22, and meanwhile, the energy storage battery 60 is closed by the energy storage control module 50, so that the energy storage battery 60 is in an operating state of not being charged or discharged.
When the commercial power normally runs and a valley filling instruction needs to be executed according to the time parameter set by the initialization setting module 10, for example, when the current time period is between 22 o 'clock and 8 o' clock in the next morning, the instruction output module 40 sends an instruction to the commercial power on-off control module 20 and the energy storage control module 50 through the data acquisition and conversion module 30, and instructs the commercial power on-off control module 20, that is, the contactor to close the communication between the commercial power and the 5G communication device, and instructs the energy storage control module 50 to communicate the energy storage battery 60 with the 5G communication device and the air conditioner lighting, so that the energy storage battery 60 discharges, and the current is converted into alternating current through direct current to supply power to the 5G communication device and the air conditioner lighting.
When the commercial power normally runs and according to the time parameter set by the initialization setting module 10, if the current time period is between 8 and 22 points, a peak clipping instruction can be executed, the instruction output module 40 outputs a command that the data acquisition and conversion module 30 detects the voltage, current, temperature and other parameters of the energy storage battery 60, and when the energy storage battery 60 is suitable for charging, the instruction output module 40 commands the commercial power on-off control module 20 to conduct the electrical connection between the commercial power and the 5G communication equipment and the air conditioner lighting, and commands the energy storage control module 50 to convert the alternating current into the direct current to charge the energy storage battery 60. When the energy storage battery 60 does not need to be charged, the instruction output module 40 only instructs the commercial power on-off control module 20 to conduct the electrical connection between the commercial power and the 5G communication equipment and the air conditioner lighting so as to supply power to the commercial power.
When the commercial power is normally disconnected, the data acquisition and conversion module 30 acquires the state and returns data to the instruction output module 40, the instruction output module 40 instructs the commercial power on-off control module 20 to disconnect the electric connection between the commercial power and the 5G communication equipment and the air conditioner lighting according to a set program, and instructs the energy storage control module 50 to connect the energy storage battery 60 and the 5G communication equipment and the air conditioner lighting, so that the energy storage battery 60 discharges to supply power to the 5G communication equipment and the air conditioner lighting.
Compared with the prior art, the intelligent control energy storage system of the 5G communication equipment provided by the invention sets the parameters for executing peak clipping and valley filling of the intelligent control energy storage system through the initialization setting module 10, so that the 5G communication equipment can supply power to the 5G communication equipment through the mains supply or the energy storage battery 60 according to the set parameters, or the mains supply charges the energy storage battery 60, and the purposes of saving energy and electricity are further achieved. Specifically, the intelligent control energy storage system comprises an instruction output module 40, a commercial power on-off control module 20, a data acquisition conversion module 30 and an energy storage control module 50, wherein the data acquisition conversion module 30 acquires various parameters of the commercial power, an energy storage battery 60 and the commercial power on-off control module 20 in real time, so that the instruction output module 40 outputs a control command for supplying power to the energy storage battery 60 by the commercial power or supplying power to a base station by the commercial power or supplying power to the base station by the energy storage battery 60, and the purpose of fully utilizing the commercial power is achieved. When the energy storage battery 60 is charged by the commercial power or the base station is powered by the energy storage battery 60, the energy storage control module 50 either directly converts the diameter into the diameter to charge the energy storage battery 60 or converts the direct current into the alternating current to power the base station, so that the purpose of fully using the energy storage battery is achieved, the energy is fully utilized, and the purpose of saving the operation cost for the communication provider is achieved.
