Description

Technical Field

[0001] The utility model belongs to the technical field of smart control terminals, and specifically relates to a smart energy control terminal device used in the new energy field. Background Art

[0002] With the rapid development of the new energy industry, the demand for smart energy control terminal devices is growing. Traditional energy control terminal devices have many shortcomings in time synchronization accuracy, positioning functions, and power supply guarantee, making it difficult to meet the demand for efficient, intelligent, and reliable management in the new energy field.

[0003] First, for new energy application scenarios that require high-precision time synchronization, such as power dispatching, photovoltaic power generation control, etc., the time synchronization performance of traditional terminal devices is difficult to meet the requirements. Furthermore, the positioning function also plays an important role in the field of new energy. For example, in a distributed photovoltaic power generation system, it is necessary to accurately grasp the geographical location information of each photovoltaic component in order to conduct power generation efficiency analysis, troubleshooting, etc. However, as disclosed in the patent number and patent name "CN219812008U_New Energy Site Source Control Terminal Device Based on 5G Communication", traditional terminal devices in the prior art usually do not have high-precision time synchronization and positioning functions, and therefore cannot meet the high requirements of the new energy field for time and positioning functions.

[0004] Furthermore, traditional end-user devices often rely solely on mains power and lack a reliable backup power solution. If the mains fails, the end-user device will not function properly, paralyzing the energy management system. This is unacceptable for renewable energy applications that require continuous operation.

[0005] In summary, traditional energy control terminal devices have significant deficiencies in time synchronization accuracy, positioning capabilities, and power supply assurance, making them unable to meet the demands of the new energy sector for smart energy management systems. Therefore, a new type of smart energy control terminal device is urgently needed to address these issues and improve the efficiency, intelligence, and reliability of new energy management systems.

[0023] The present invention will be further described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] The utility model provides a smart energy control terminal device for the new energy field, such as Figure 1 As shown, it includes a central control unit, a communication unit, a time synchronization and positioning unit and a power module. The communication unit and the time synchronization and positioning unit are respectively connected to the central control unit. In this embodiment, the central control unit adopts Rockchip's self-controllable RK3568J processor.

[0025] The communication unit includes an RS485 / RS232 communication module, a network communication module and a Bluetooth module. The RS485 / RS232 communication module is connected to the central control unit. Figure 2As shown, including RS485 interface, RS232 interface, RS485 / RS232 shared serial port conversion circuit and isolation drive circuit, the RS485 interface and the RS232 interface are respectively connected to the input end of the serial port conversion circuit, the output end of the serial port conversion circuit is connected to one end of the isolation drive circuit, and the other end of the isolation drive circuit is connected to the central control unit; in this embodiment, 4-way RS485 / RS232 communication modules can be set, each of which can only receive RS485 or RS232 signals at the same time, and the 4-way RS485 / RS232 communication modules are independent of each other, including a total of up to 4 RS485 or up to 4 RS232 signal transmission channels. The present embodiment can effectively reduce the use of wires by arranging the RS485 / RS232 serial port conversion circuit, making wiring work more simplified and reducing the complexity of installation and maintenance. By arranging multiple RS485 / RS232 communication modules independently of each other, multiple different communication tasks can be handled simultaneously, improving the communication flexibility of the device.

The Bluetooth module enables the device to exchange data with other external devices with Bluetooth functionality or to perform human-computer interaction via short-range wireless communication via an app.

[0028] The structure of the timing and positioning unit is as follows Figure 3As shown, the system includes a timing and positioning control module. The inputs of the timing and positioning control module are connected to an IRIG-B code signal processing module and a GPS / BD positioning processing module, respectively. The input of the IRIG-B code signal processing module is connected to a high-precision time source via an IRIG-B code timing signal interface. The high-precision time source can be a high-precision clock system based on a satellite navigation system such as GPS or Beidou, or other master clock server. The time signal generated by these systems is processed to generate an IRIG-B code timing signal. The IRIG-B code signal processing module receives and parses the IRIG-B code timing signal transmitted from the high-precision time source. By parsing the IRIG-B code timing signal, the IRIG-B code signal processing module extracts accurate time information and transmits it to the timing and positioning control module.

Among them, the GPS / BD positioning processing module is a mature module in the existing technology, such as the positioning module disclosed in the patent "CN119001776A_A multifunctional Beidou communication terminal and its method"; the time synchronization and positioning control module integrates this information and outputs it to the central control unit, and is finally used to provide accurate time and positioning services for the smart energy control terminal device and external equipment. Among them, the time synchronization and positioning control module is a program that can be set to integrate and output the time positioning information through program settings. It is a program that is easy to implement in the existing technology and is not described here.

[0029] The power supply unit structure is as follows Figure 4 As shown, the power supply unit is connected to the central control unit and the display unit respectively, and the power supply unit can provide uninterruptible power supply to the central control unit and the display unit.

In application, when the mains power supply is selected as the main power supply mode, if the mains power supply is suddenly cut off, the UPS module can immediately switch to providing power through the battery module; when the battery module is selected as the main power supply mode, if the battery power is insufficient, the UPS power module can promptly obtain the power signal of the power detection module and switch the power supply mode from the battery module to the mains power supply.

[0030] It also includes a storage unit, which is connected to the central control unit and is used for storing and reading data.
