DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Figures 2 to 3 The load control system and method provided by the embodiment of the present application with direct information connection between the concentrator and the orderly charging piles are described in detail.

[0029] Please refer to Figure 2 , which is a load control system provided by an embodiment of the present application in which a concentrator is directly connected to orderly charging piles. The load control system 1 includes a concentrator 11 and an orderly charging pile group 13 connected to the concentrator 11 via an optical fiber communication network 12. The orderly charging pile group 13 includes multiple orderly charging piles 131. The orderly charging piles 131 include at least one of AC charging piles and DC charging piles. The orderly charging piles 131 can dynamically adjust the charging sequence or automatically reduce the output power according to the load of the power grid, thereby ensuring that the electricity demand of residents is met first during peak hours. At the same time, autonomous charging is performed during periods of low electricity prices, reducing costs for car owners and saving waiting time.

[0030] The concentrator 11 includes a communication adapter module 111 and a data processing module 112, which are interconnected. This module integrates a built-in software package into the concentrator 11's hardware to optimize the configuration of the relevant software modules. For example, a Type I concentrator 11 has greater storage capacity and supports more communication methods, such as downlink 485 communication and uplink carrier communication. In actual use, the communication adapter module 111 parses messages sent by each ordered charging station 131 and, based on these messages, establishes a communication connection between the ordered charging station 131 and the concentrator 11 using the optical fiber communication network 12. These messages include the communication protocol and charging data. This configuration offers compatibility with multiple communication protocols used by ordered charging stations 131, such as the 698 protocol, ensuring efficient and stable data exchange between the concentrator 11 and ordered charging stations 131 of different brands and models. Test results show that connection establishment time has been reduced from an average of 1-2 minutes to less than 30-40 seconds, significantly improving the response speed and connection efficiency of ordered charging.

[0031] The data processing module 112 can perform real-time analysis on charging data, such as charging data including but not limited to charging status, power demand and power information, and generate charging control instructions corresponding to the charging data according to the preset charging strategy, and then send the charging control instructions to the orderly charging pile 131. For example, the preset charging strategy is to adjust the charging power when the charging power is greater than the preset threshold, and the corresponding charging control instruction is to reduce the charging power until charging is stopped. The advantage of this setting is that it can accurately control the charging process of the orderly charging pile 131, improve charging efficiency, avoid problems such as overcharging and undercharging, and extend battery life. Test results show that the charging efficiency is improved by an average of 15% to 20%.

[0032] In some embodiments of the present application, the concentrator 11 further includes a device management module 113, which is capable of remotely and in real time monitoring the charging load and operating status of each ordered charging pile 131. The advantage of this configuration is that all ordered charging piles 131 connected to the concentrator 11 can be uniformly managed, and device information and operating status can be recorded, facilitating rapid diagnosis and fault location. Maintenance personnel can thus remotely monitor and maintain the ordered charging piles 131 through the built-in software package of the concentrator 11, eliminating the need to conduct on-site inspections one by one. This significantly reduces maintenance difficulty and cost, and improves operation and maintenance efficiency. Furthermore, the device management module 113 can also group and manage the ordered charging piles 131. Different groups of ordered charging piles 131 have different charging permissions. For example, some groups of ordered charging piles 131 can be fast charged, while other groups of ordered charging piles 131 can be charged at a normal rate. Charging permissions can be assigned to different vehicles, adapting to the local networking environment of charging pile groups within residential communities and meeting diverse usage needs.

[0033] In some embodiments of the present application, the optical fiber communication network 12 includes a plurality of conversion modules 121 connected in series via optical fibers. The conversion modules 121 correspond one-to-one to the ordered charging piles 131. The RS-485 interface of the conversion module 121 is connected to the RS-485 interface of the ordered charging pile 131 via a 485 line. The two conversion modules 121 at the edge of the communication network are connected to the concentrator 11 via an optical fiber. The power consumption of the conversion module 121 is 0.1 to 0.2 watts. For example, the optical fiber is a plastic optical fiber. The advantage of such a setting is that on the one hand, the plastic optical fiber is transmitted by the principle of total reflection. The light propagates inside the optical fiber in the form of a visible light signal rather than an electrical signal. The optical signal is not affected by electromagnetic interference. Even in an environment with strong electromagnetic interference such as near large motors, transformers and radars, the optical signal in the plastic optical fiber can still be transmitted normally without problems such as signal distortion, attenuation or bit errors. At the same time, in the plastic optical fiber communication network, the plastic optical fiber is transmitted by visible light. The light source of the visible light is an LED green light emitting tube with a central wavelength of 520 nanometers. The transmission distance of the signal is less than or equal to The distance is less than 300 meters, and it has the advantages of high communication quality, reliability, anti-interference and real-time performance, which meets the needs of stable communication between the concentrator 11 and the orderly charging piles 131. On the other hand, in the single-core half-duplex closed-loop communication network architecture based on plastic optical fiber, each orderly charging pile 131 shares the plastic optical fiber network and is connected to the concentrator 11. The communication of other charging piles will not be affected by the failure or fiber break of a single charging pile, which greatly improves the reliability of network transmission and simplifies the wiring structure. Test results show that the wiring length can be shortened by 40% to 60%, and the procurement and construction costs of access units and related equipment are eliminated.

[0034] In some embodiments of the present application, the load control system 1 also includes an electricity consumption information collection system 14 connected to the concentrator 11 via a remote wireless public network, for example, the wireless public network includes but is not limited to 4G communication network and 5G communication network.

[0035] The load control system provided by the embodiment of the present application has a direct information connection between the concentrator and the orderly charging piles. In terms of hardware, the concentrator and the orderly charging pile group including multiple orderly charging piles are directly connected through an optical fiber communication network, which improves the quality of information transmission. There is no need to use access units and redundant carrier transmission channels, which can simplify the wiring structure and effectively reduce construction costs. At the same time, in terms of software, the communication adapter module of the concentrator can parse the message sent by each orderly charging pile, which includes a communication protocol and charging data, thereby quickly connecting the orderly charging piles and the concentrator, and the data processing module of the concentrator can analyze the charging data and generate charging control instructions corresponding to the charging data according to a preset charging strategy. The charging control instructions are then sent to the orderly charging piles, thereby accurately controlling the charging process of the orderly charging piles, improving charging efficiency, and ensuring the orderly operation of the charging piles. The combination of software and hardware realizes efficient and reliable information exchange between the concentrator and the orderly charging piles.

[0036] Based on the above embodiments, the present invention provides a load control method, which can be used to Figure 2 The load control system 1 of the corresponding embodiment.

The two conversion modules 121 at the edge of the communication network are connected to the concentrator 11 through optical fibers. The optical fibers are plastic optical fibers, which have the advantages of high communication quality, reliability, anti-interference and real-time performance, and also simplify the wiring structure.

Maintenance personnel can thus remotely monitor and maintain the orderly charging piles 131 through the built-in software package of the concentrator 11 without having to go to the site to check one by one, which greatly reduces the difficulty and cost of maintenance and improves operation and maintenance efficiency.
