[0023] The utility model provides a photovoltaic and energy storage two-in-one farmland power system with charging identification, including a power supply device 10, an AC power supply plug 211, a DC power supply plug 212, an identification module 22, a photovoltaic module 30, and an energy storage module 31;

[0024] The power supply device 10 is provided with an AC power supply socket 111 , a DC power supply socket 112 , an AC power supply control module 121 , a DC power supply control module 122 and a DC / AC module 13 ;

[0025] The photovoltaic module 30 is connected to the DC / AC module 13 and the DC power supply socket 112 respectively through the energy storage module 31; the DC / AC module 13 is connected to the AC power supply socket 111;

[0026] The AC power supply control module 121 is connected to the AC power supply socket 111; the DC power supply control module 122 is connected to the DC power supply socket 112;

[0027] The AC power socket 111, the DC power socket 112 and the AC power plug 211, the DC power plug 212 are all provided with a CC terminal and a CP terminal, and communicate through the CC terminal and the CP terminal;

[0028] The CC ends of the AC power plug 211 and the DC power plug 212 are respectively provided with an identification module 22;

[0029] The AC power plug 211 and the DC power plug 212 are used to connect to the irrigation device 20 .

[0030] When implementing it specifically, Figure 1-3 As shown, the utility model provides a photovoltaic and energy storage two-in-one farmland power system with charging identification, including a power supply device 10, an AC power supply plug 211, a DC power supply plug 212, an identification module 22, a photovoltaic module 30, and an energy storage module 31;

[0031] The power supply device 10 is provided with an AC power supply socket 111 , a DC power supply socket 112 , an AC power supply control module 121 , a DC power supply control module 122 and a DC / AC module 13 ;

[0032] The photovoltaic module 30 is connected to the DC / AC module 13 and the DC power socket 112 through the energy storage module 31; the DC / AC module 13 is connected to the AC power socket 111; the solar energy is stored through the energy storage module 31 and supplies power to the DC power socket 112 and the AC power socket 111, thus achieving AC and DC power supply;

[0033] The AC power supply control module 121 is connected to the AC power supply socket 111; the DC power supply control module 122 is connected to the DC power supply socket 112;

[0034] like Figure 2 As shown, the AC power socket 111, the DC power socket 112 and the AC power plug 211, the DC power plug 212 are all provided with a CC terminal and a CP terminal, and communicate through the CC terminal and the CP terminal;

[0035] The CC terminals of the AC power plug 211 and the DC power plug 212 are each equipped with an identification module 22. The AC power plug 211 and the DC power plug 212 are used to connect to the irrigation device 20. The CC terminal of the AC power control module 121 communicates with the CC terminal of the inserted AC power plug 211 and identifies the identification module 22 of the irrigation device 20 through the CC terminal. Only when the identification is successful can power be transmitted (the identification method for DC and AC is the same and will not be repeated here).

[0036] During use, the photovoltaic solar energy laying unit installs the AC power plug 211 or the DC power plug 212 and the identification module 20 on the farmer's irrigation device 20 .

[0037] The existing national standard AC charging pile plug is usually equipped with a CC identification terminal. Currently, this line is connected to the ground wire in the market, and the identification function is not activated. In this embodiment, by connecting the identification module 22 to the CC identification terminal, the use of components can be reduced while realizing the identification function, thereby saving costs.

[0038] The internal circuit structure and principles of the plug and socket can adopt the charging pile and plug structure disclosed in Chinese Patent Publication No. CN104029604A. The AC and DC power supply control modules are turned on and off by existing methods, including but not limited to internal relays, and their structures are commonly used in this field. In this embodiment, the AC power socket 111, DC power socket 112, AC power control module 121, DC power control module 122, DC / AC module 13, AC power plug 211, DC power plug 212, irrigation device 20, photovoltaic module 30, and energy storage module 31 all utilize existing commercial modules and will not be described in detail here.

[0039] The photovoltaic and energy storage two-in-one farmland power system with charging identification provided by the embodiment of the present invention achieves the purpose of AC and DC power supply to farmland in remote areas through the design of the power supply device 10, AC power plug 211, DC power plug 212, identification module 22, photovoltaic module 30, energy storage module 31, AC power socket 111, DC power socket 112, AC power supply control module 121, DC power supply control module 122 and DC / AC module 13; and, by identifying the irrigation device 20 through the identification module 22, the problem that photovoltaic solar energy laying units in remote areas cannot effectively and timely identify rechargeable irrigation devices is solved, and the utility model can be widely used in agricultural power supply.

[0040] Furthermore, a DC / DC module is provided between the energy storage module 31 and the DC power supply socket 112 .

[0041] In specific implementations, a DC / DC module (not labeled in the figure) is provided between the energy storage module 31 and the DC power socket 112. The DC / DC module can be an existing product based on output requirements. The DC / DC module converts voltage and stably outputs the electrical energy in the energy storage module 31 to the DC power socket 212, ensuring the safety of DC charging.

[0042] Furthermore, the identification module 22 is a resistor R1.

[0043] Furthermore, the resistance of the resistor R1 is one of 4.55K, 4.85K, and 5.25K.

[0044] When implementing it specifically, Figure 2As shown, the identification module 22 is a resistor R1; the resistance value of the resistor R1 is one of 4.55K, 4.85K, and 5.25K. When the plug 21 is inserted into the socket 11, the power supply control device 12 detects and identifies the resistor R1 connected to the CC detection port. If the detected resistance value is within the value or value range stored in its internal program, it is judged as legal electricity use and normal power supply output is started; otherwise, no power is supplied. By combining the resistor R1 with the CC detection port structure, the circuit composition is simple and practical, which can greatly reduce production costs. In addition, the resistor R1 adopts a special resistance specification. For example, in this field, 4.55K, 4.85K, and 5.25K are special resistance values ​​that are not easy to purchase and some need to be customized. Therefore, the recognition error can be reduced and the recognition accuracy can be improved.

[0045] Furthermore, the identification module 22 is an ID chip.

[0046] In a specific implementation, the identification module 22 is an ID chip. This embodiment uses an I / O port of the detection circuit chip within the existing power supply control device 12 to sample and determine the CC detection point. When the identification module 22 is an ID chip, the power supply control device 12 checks the pulse signal passing through the CC detection port to make a determination. Using an ID chip increases the difficulty of circuit analysis.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
