Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a control system of an energy storage device group according to an embodiment of the present invention. Specifically, referring to fig. 1, the energy storage device group control system includes: the system comprises a central control device 10, a cloud server 20 and at least two terminal control devices 30, wherein the cloud server 20 and the at least two terminal control devices 30 are respectively connected with the central control device 10; the central control device 10 comprises a first communication port 101, a signal processing module 103 and at least two second communication ports 102; the central control device 10 is in communication connection with the cloud server 20 through a first communication port 101; the signal processing module 103 includes at least two independently operating signal processing units 113; the signal processing units 113 are in one-to-one correspondence with and connected to the second communication ports 102; each terminal control device 30 comprises a data acquisition module 301, a control output module 302 and a terminal communication port 303; the data acquisition module 301 and the control output module 302 are both connected with a terminal communication port 303, and the terminal communication port 303 and the second communication port 102 are in one-to-one correspondence and communication connection; the data acquisition module 301 includes a position information acquisition unit 311, a temperature information acquisition unit 321, and an electric quantity information acquisition unit 331.
Specifically, the energy storage device is generally installed near a solar power generation apparatus or a wind power generation apparatus to store surplus electric energy generated by the power generation apparatus during a power generation peak period of the solar power generation apparatus or the wind power generation apparatus, and to externally output the electric energy during a period when the power generation amount of the power generation apparatus such as a solar module or a wind power generation vehicle module is low. In general, a power plant often has a plurality of power generation devices, and accordingly, a plurality of energy storage devices are also required to store electric energy. In order to ensure that a plurality of energy storage devices work efficiently and orderly, in actual production, an energy storage device group control system is often used for controlling the energy storage device group to work.
More specifically, the central control device 10 in the energy storage device group control system provided in this embodiment may be located in a control room, and the terminal control device 30 is often installed in an outdoor environment where the power generation device is located together with the energy storage device group. The second communication port 102 is in communication connection with the terminal communication port 303, so that data interaction between the central control device 10 and the terminal communication device 30 is realized.
The electric quantity information acquisition unit 331 in the data acquisition module 301 can acquire an electric quantity signal of the energy storage device, and sequentially sends the electric quantity signal to the signal processing module 113 in the central control device 10 through the terminal communication port 303 and the second communication port 102, and after analysis processing by the signal processing module 113, the electric quantity information in the energy storage device can be obtained. When the power generation device starts to enter a power generation peak period, the electric quantity in the energy storage device tends to be low, at this time, the signal processing module 113 may generate a charging instruction for controlling the energy storage device to be charged, and transmit the charging instruction to the control output module 302 through the second communication port 102 and the terminal communication port 303 in sequence, so that the control output module 302 executes an action for controlling the energy storage device to start charging. Similarly, when the power generation device starts to enter the power generation valley period, the amount of power in the energy storage device is large, and the amount of power generated by the power generation device is small, the signal processing module 113 may generate a discharge instruction for controlling the energy storage device to discharge according to the power signal provided by the power information collecting unit 331, so that the control output module 302 controls the energy storage device to perform the operation of discharging to the electrical appliance.
Similarly, when a certain energy storage device is in a charging or discharging process, if the signal processing module 103 finds that the temperature corresponding to the temperature signal of the energy storage device provided by the temperature information collecting unit 321 is too high, the signal processing unit 113 corresponding to the energy storage device may also control the energy storage device to suspend operation, so that the temperature of the energy storage device is restored to a normal range. Similarly, through the position information collecting unit 311, the central control device 10 can obtain the position signal of each terminal control device 30 and the energy storage device corresponding to the terminal control device, so as to obtain the position information of the energy storage device; since the position of the power generation device is often fixed, the signal processing unit 113 can adjust the position of the terminal control device 30 and the corresponding energy storage device through the control output module 302 according to the relative position between the power generation device and the terminal control device 30.
It is understood that, in order to achieve precise personalized control, the number of the signal processing units 113, the number of the second communication ports 102, and the number of the terminal control devices 30 which can be independently operated are all equal in the present embodiment. In practical operation, each signal processing unit 113 can collect and control and manage signals of one terminal control device through one second communication port 102. Because the information collected by each terminal control device 30 can be independently processed in the central control device 10, and the data signals provided by different terminal control devices 30 can be simultaneously and independently processed, the central control device 10 can timely acquire the working condition of each energy storage device through the data collection module 301, and can reasonably control the working mode and state of the energy storage device at the working stage of each energy storage device, thereby realizing the individual control of the energy storage device. For example, the energy storage device group control system provided by this embodiment can control a part of the energy storage devices to be in a constant-current fast charging state, and control another part of the energy storage devices to be in a constant-voltage slow charging state.
It should be noted that, in describing the operating principle of the energy storage device group control system provided in this embodiment, although the energy storage device is used for illustration in this embodiment, it should be understood that this is only for more clearly introducing the energy storage device group control system provided in this embodiment to the reader, and the structure and the function of the energy storage device group control system provided in this embodiment are not implemented depending on the energy storage device. In actual production, the control system of the energy storage device group provided by the embodiment can be used as an independent product to be produced independently, and can also be used in combination with energy storage devices to be produced integrally. Although the number of the terminal control devices 30 in the energy storage equipment group control system in fig. 1 is 2, it should be understood that this is only one possible embodiment, and in practice, the number of the terminal control devices 30 may be set to two or more according to specific needs, and the number of the signal processing units 113 and the second communication ports 102 is also two or more accordingly.
The energy storage equipment group control system provided by the embodiment can realize independent control of each terminal control device and the corresponding energy storage equipment thereof by setting the plurality of independently operated signal processing units, so as to realize accurate and individualized control of each energy storage equipment and improve the working efficiency of the energy storage equipment group.
It should be further noted that, if the energy storage device is provided with a movable universal wheel and a motor for providing power for the universal wheel, the terminal control device 30 and the energy storage device corresponding thereto can be adjusted in position by controlling the central control device 10 located indoors, so that the positions of the energy storage devices can be reduced, the working conditions for manually positioning the energy storage devices and manually carrying the energy storage devices can be reduced, and the installation efficiency of the energy storage device group control system and the energy storage devices can be improved.
Fig. 2 is a schematic structural diagram of a control output module according to an embodiment of the present invention. Optionally, referring to fig. 1 and fig. 2, the control output module 302 provided in this embodiment may further include a signal conversion circuit 312, a charging control switch 322, a discharging control switch 332, and a motion control switch 342; an input terminal of the signal conversion circuit 312 is connected to the terminal communication port 303, and an output terminal of the signal conversion circuit 312 is connected to the charge control switch 322, the discharge control switch 332, and the motion control switch 342, respectively.
Specifically, the signal conversion circuit 312 is configured to receive a control instruction from the terminal control port 303 and convert the control instruction into a signal for controlling the charging control switch 32, the discharging control switch 332, or the motion control switch 342 to be opened or closed. For example, if the command from the terminal control port 303 is a command for controlling the charging of the energy storage device, the signal conversion circuit 312 may generate a command for controlling the circuit where the charging control switch 322 is located to form a path, so as to start charging the corresponding energy storage device; if the command from the terminal control port 303 is a command for controlling the discharge of the energy storage device, the signal conversion circuit 312 may generate a signal for controlling the circuit where the discharge control switch 332 is located to form a path, so as to start the discharge of the corresponding energy storage device; if the command from the terminal control port 303 is a command for controlling the movement of the energy storage device, the signal conversion circuit 312 may generate a command for controlling the circuit forming path of the motion control switch 342, so that the energy storage device and the terminal control apparatus 30 may be adjusted in position by a universal wheel or the like.
Optionally, with continued reference to fig. 1 and 2, the charge control switch 322 comprises a first normally open relay; the discharge control switch 332 includes a second normally open relay; the motion control switch 342 includes a third normally open relay.
Specifically, when no control signal is applied, the normally open relay is normally in an off state, taking the charging control switch 322 as an example, the circuit where the charging control switch 322 is located is in an off state at this time, and the energy storage device cannot receive the electric energy generated by the power generation device and cannot store the electric energy, so that the energy storage device cannot be charged. After the terminal control port 303 receives the charging control instruction, the normally open relay is in a closed state, the circuit where the charging control switch 322 is located at this time is in a connected state, the energy storage device can receive electric energy generated by the power generation device, and the electric energy can be stored, so that the energy storage device can be charged. Similarly, for the discharge control switch 332 or the motion control switch 342, the normally open relay also has similar technical effects, and is not described in detail. It should also be understood that, when describing the normally open relay, the present embodiment is assisted by the words "first", "second", and "third", and these words are used for convenience of description only and do not represent the differences of the normally open relay itself; in fact, the relay is normally opened to first normally open relay, second and the third normally open relay can be the same normally open relay, also can be the normally open relay of difference, and this embodiment does not do specific restriction to this.
Alternatively, the signal processing module 103 may include a micro control unit or a single chip microcomputer.
Specifically, a Micro Controller Unit (MCU) is a technically mature microprocessor, and has the advantages of powerful function, wide application, fast processing speed, low power consumption, and the like. The single chip microcomputer has the advantages of small volume, light weight, high cost performance, convenience in development and application and the like. Therefore, in the present embodiment, a micro control unit or a single chip microcomputer may be used as a core component of the signal processing module 103 to perform data analysis processing. In addition, the signal processing module 103 provided in this embodiment may also include other devices besides a micro control unit or a single chip, which is not specifically limited in this embodiment.
Optionally, the first communication port 101 may include a first wireless communication unit; the second communication port 102 may include a second wireless communication unit; the terminal communication port 303 may include a third wireless communication unit.
It should be noted that, in fig. 1, the first communication port 101 is connected to the cloud server 30 by a dashed line with a double-headed arrow, which indicates that the first communication port 101 communicates with the cloud server 30 in a wireless manner. This configuration has an advantage that it is possible to avoid the installation location of the central control device 10 where the first communication port 101 is located from being limited by the location of the cloud server 20, and thus flexibility in installation of the central control device 10 can be improved. However, it should be understood that the first communication port 101 and the cloud server 30 may communicate with each other in other communication manners if conditions allow. Similarly, in fig. 1, the dashed lines with double arrows of the terminal communication port 303 and the second communication port 102 also indicate that the terminal communication port 303 and the second communication port 102 communicate wirelessly. This arrangement has the advantage that the installation positions of the central control device 10 and the terminal control device 20 can be more flexible, and the working range of the central control device 10 and the terminal control device 303 can be increased. Similarly, the terminal communication port 303 and the second communication port 102 may communicate with each other by other methods such as a wire. It should be noted that, in describing the wireless communication unit, the present embodiment uses the concepts of "first", "second", and "third", which are only for the purpose of description and do not represent the difference of the wireless communication unit itself, and actually, the first wireless communication unit, the second wireless communication unit, and the third wireless communication unit may be the same or different wireless communication devices, and the present embodiment does not specifically limit this.
Alternatively, the position information collecting unit 311 may include a position sensor; the temperature information acquisition unit 321 may include a temperature sensor; the electricity amount information collecting unit 331 may include an electricity amount sensor.
Specifically, as a core component of the position information collecting unit 311, the position sensor may be configured to obtain position information, so as to locate the positions of the energy storage device and the terminal control device 30. Similarly, as a core component of the temperature information collecting unit 321, the temperature sensor may be configured to obtain temperature information of the energy storage device and the terminal control apparatus 30, and further detect whether the energy storage device and the terminal control apparatus 30 operate in a normal temperature range. As a core component of the electric quantity information acquisition unit 331, the electric quantity sensor is configured to acquire electric quantity information of the energy storage device, and the central control device 10 controls the energy storage device to operate in a reasonable charging mode or a reasonable discharging mode according to the electric quantity information provided by the electric quantity information acquisition unit 331.
It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
