Description

Technical Field

[0001] The present invention belongs to the technical field of load control, and in particular relates to an information management method and device for load control. Background Art

[0002] Load control is to take appropriate measures to limit and adjust the power load in a planned manner according to the power supply capacity of the power grid, so as to ensure the balance between power supply and demand and minimize the losses and impacts caused by limiting the power load.

[0003] In terms of load control, the existing technical solution with patent publication number "CN113300464B" is often used to perform load control, which includes a nearby collection station that is communicatively connected to the load control terminal. The load control terminal is used to transmit status information and data information to the nearby collection station. The nearby collection station is used to generate terminal information elements based on the status information and data information. The status information or data information is the information for load control.

[0004] The way the load control terminal transmits the load control information to the nearest aggregation station is mainly through the DTLS standard method. The DTLS standard is not expensive and is suitable for small bandwidth scenarios. However, the DTLS standard does not have the characteristics of security and bandwidth control, which makes the transmission of load control information without security barriers. Summary of the invention

[0005] In order to solve the defects in the prior art, the present invention proposes an information management device and method for load control, wherein the load control terminal performs segmented processing on the load control information based on the recognized form information, and then transmits it to the nearest collection station via the transmission pipe PIPE. The nearest collection station analyzes the information and returns the recognition header to the load control terminal. The load control terminal removes the information of the transmission pipe PIPE after receiving the recognition header. This method ensures that the information can be transmitted completely in scenarios with small bandwidth and unstable communication channels.

[0006] The present invention uses the following technical solutions.

[0007] A method for information management of load control, comprising:

[0008] The load control terminal transmits the status information and data information to the nearest collection station, and the nearest collection station generates terminal information elements based on the status information and data information. The status information or data information is the information of load control;

[0009] The method for the load control terminal to transmit the status information and data information to the nearest collection station includes:

[0010] Step 1, the load control terminal and the nearest collection station identify the form information of the sub-segment information;

[0011] Step 2: The load control terminal processes the load control information in sections to form sub-section information that conforms to the format information;

[0012] Step 3: The load control terminal sends the sub-segment information to the transmission pipeline PIPE and transmits it to the nearest collection station;

[0013] Step 4: The nearest collection station analyzes the sub-segment information, decomposes the identification information and transmits it back to the load control terminal;

[0014] Step 5: After receiving the identification information, the load control terminal removes the initial sub-segment information through the transmission pipe PIPE.

[0015] Furthermore, in step 1, the format information of the sub-segment information includes a sub-segment message header and an information body.

[0016] Furthermore, the sub-segment message header includes: identification header + total capacity of load control information + number of sub-segments + sequence code of sub-segments + sub-segment information capacity; the information body is the valid value of the sub-segment.

[0017] Furthermore, in step 2, the condition of the segment processing is that the information capacity of the load control is higher than five hundred characters.

[0018] Furthermore, in step 3, the load control terminal sends the sub-segment information into the transmission pipeline PIPE and transmits it to the nearest collection station, comprising:

[0019] The load control terminal maintains a transmission pipe PIPE, the transmission pipe PIPE starts with NULL, and when transmitting information, the segmented information is sent to the transmission pipe PIPE. The information transmission process repeatedly obtains information through the transmission pipe PIPE and transmits it to the nearest collection station.

[0020] Furthermore, the information transmission process repeatedly obtains information through the transmission pipe PIPE, and transmits it to the nearest collection station after a delay of several ms.

[0021] Furthermore, in step 4, the method in which the nearest aggregation station analyzes the sub-segment information, decomposes the identification information and transmits it back to the load control terminal includes:

[0022] After receiving the information, the nearest collection station reconstructs the information based on the sub-segment message header, and then returns the identification header to the load control terminal.

[0023] Furthermore, the information management method for load control also includes: if the load control terminal does not receive the identification information, the load control terminal will re-transmit the sub-segment information in the transmission pipeline PIPE to the nearest collection station until the load control terminal receives the identification information, and then remove the initial sub-segment information through the transmission pipeline PIPE.

[0024] An information management device for load control, comprising:

[0025] The nearest collection station is connected to the load control terminal in communication. The load control terminal is used to transmit the status information and information to the nearest collection station. The nearest collection station is used to generate terminal information elements based on the status information and information. The status information or information is the load control information.

[0036] Figure 2 It is a partial structural diagram of the information management device for load control in the present invention. DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely expressed in combination with the drawings in the embodiments of the present invention. The embodiments expressed in this application are only some embodiments of the present invention, not all embodiments. According to the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the protection scope of the present invention.

[0038] like Figure 1 As shown, a load control information management method according to the present invention comprises:

[0039] The load control terminal transmits the status information and data information to the nearest collection station, and the nearest collection station generates terminal information elements based on the status information and data information. The status information or data information is the information of load control;

[0040] The method for the load control terminal to transmit the status information and data information to the nearest collection station includes:

[0041] Step 1, the load control terminal and the nearest collection station identify the form information of the sub-segment information;

[0042] Step 2: The load control terminal processes the load control information in sections to form sub-section information that conforms to the format information;

[0043] Step 3: The load control terminal sends the sub-segment information to the transmission pipeline PIPE and transmits it to the nearest collection station;

[0044] Step 4: The nearest collection station analyzes the sub-segment information, decomposes the identification information and transmits it back to the load control terminal;

[0045] Step 5: After receiving the identification information, the load control terminal removes the initial sub-segment information through the transmission pipe PIPE.

[0046] The load control terminal performs segmented processing on the load control information based on the identified format information, and then transmits it to the nearest collection station through the transmission pipeline PIPE. The nearest collection station analyzes the information and returns the identification header to the load control terminal. The load control terminal removes the information on the transmission pipeline PIPE after receiving the identification header. This method ensures that the information can be transmitted completely in scenarios with small bandwidth and unstable communication channels.

[0047] The DTLS specification is a non-link, secure transmission specification for information, which has two problems:

[0048] 1. Information is often lost;

[0049] 2. Information messages are out of order; to ensure their security and application within a small bandwidth, several modes must be achieved.

[0050] Just as: information message recognition rule: when the nearest collection station receives information, it feeds back the recognition header to perform recognition; retransmission rule: the nearest collection station analyzes the information and recognizes it to the load control terminal. When the load control terminal recognizes that the nearest collection station has received the information, it removes the information of the transmission pipeline PIPE. If the load control terminal does not receive the recognition information transmitted by the nearest collection station, it performs repeated transmission. Only when the recognition information is received, the information of the transmission pipeline PIPE is removed; sequence code rule: the load control terminal and the nearest collection station must first recognize the format information of the sub-segment information to ensure that both parties can reasonably analyze the information and can use the counting system to set the format.

[0051] In a preferred but non-limiting embodiment of the present invention, in step 1, the format information of the sub-segment information includes a sub-segment message header and an information body.

[0052] In a preferred but non-limiting embodiment of the present invention, the sub-segment message header includes: identification header + total capacity of load control information + number of sub-segments + sequence code of sub-segments + sub-segment information capacity; the information body is the valid value of the sub-segment.

[0053] The load control terminal and the nearest collection station must first identify the form of the sub-segment information to ensure that they can analyze the information reasonably. Here, the form of Hex number system is used as an example;

[0054] Just as: 3781010D24C628670F54160E24C62846….

[0055] Here, 3781010D24C628670F54 is the sub-segment message header, followed by the information body.

[0056] In a preferred but non-limiting embodiment of the present invention, in step 2, the condition of the segmentation processing is that the information capacity of the load control is higher than five hundred characters.

[0057] In actual application, if the information message exceeds the maximum transmission unit size, which is 1,500 characters, the DTLS specification will automatically segment the information message, causing information loss. The maximum transmission unit size set in different communication channels is different. The standard maximum transmission unit size on the channel is 576 characters. Therefore, before transmitting information, the transmitted information must be actively segmented and the information message capacity must be controlled below 500 characters.

[0058] In a preferred but non-limiting embodiment of the present invention, in step 3, the load control terminal sends the sub-segment information into the transmission pipeline PIPE and transmits it to the nearest collection station, comprising:

[0059] The load control terminal maintains a transmission pipe PIPE, the transmission pipe PIPE starts with NULL, and when transmitting information, the segmented information is sent to the transmission pipe PIPE. The information transmission process repeatedly obtains information through the transmission pipe PIPE and transmits it to the nearest collection station.

[0060] The load control terminal meteorology must perform segmented processing on the information to be transmitted, process it into a pre-set format, and then send the information into the transmission pipeline PIPE; the pipeline PIPE is just like: PIPE = {information one, information two, information three,.....}, and the information is obtained through the pipeline PIPE and transmitted to the nearest collection station.

[0061] In a preferred but non-limiting embodiment of the present invention, the information transmission process repeatedly obtains information from the transmission pipe PIPE and transmits it to the nearest collection station after a delay of several ms.

[0062] The load control terminal must maintain a transmission pipe PIPE, which starts with NULL. When transmitting information, the load control terminal sends the segmented information into the pipe PIPE. The information transmission process repeatedly obtains information through the pipe PIPE and transmits it to the nearest collection station, which reduces the possibility of message loss due to the nearest collection station's untimely processing of information, and can delay the transmission by 1ms.

[0063] In a preferred but non-limiting embodiment of the present invention, in step 4, the method in which the nearest aggregation station analyzes the sub-segment information, decomposes the identification information and transmits it back to the load control terminal includes:

[0064] After receiving the information, the nearest collection station reconstructs the information based on the sub-segment message header, and then returns the identification header to the load control terminal.

[0065] After receiving the information, the nearest collection station analyzes the information according to the set format, and then transmits the confirmed information back to the load control terminal.

[0066] After receiving the returned information, the load control terminal removes the information to be transmitted from the pipeline PIPE; if the returned information is the identification header of information 2, the pipeline PIPE is like: PIPE = {information one, information three,...}, and transmits the information one by one until the information transmission is completed. To prevent excessive information transmission from causing information congestion, the load control terminal will constrain the capacity of the transmission pipeline PIPE based on the channel performance.

[0067] In a preferred but non-limiting embodiment of the present invention, the information management method for load control also includes: if the load control terminal does not receive the identification information, the load control terminal will re-transmit the sub-segment information in the transmission pipeline PIPE to the nearest collection station until the load control terminal receives the identification information, and then remove the initial sub-segment information through the transmission pipeline PIPE.

[0068] like Figure 2 As shown, the information management device for load control described in the present invention includes:

[0069] The nearest collection station is connected to the load control terminal in communication. The load control terminal is used to transmit the status information and information to the nearest collection station. The nearest collection station is used to generate terminal information elements based on the status information and information. The status information or information is the load control information.

[0070] The information management device for load control also includes:

[0071] Identification module, which is used for the load control terminal and the nearest collection station to identify the form information of the sub-segment information;

[0072] The segmentation module is used for the load control terminal to segment the load control information to form sub-segment information that conforms to the formal information;

[0073] The transmission module is used for the load control terminal to send the sub-segment information into the transmission pipeline PIPE and transmit it to the nearest collection station;

[0074] Decomposition module, which is used to analyze sub-segment information at the nearest collection station, decompose the identification information and transmit it back to the load control terminal;

[0075] The removal module is used for the load control terminal to remove the initial sub-segment information through the transmission pipe PIPE after receiving the identification information.

[0076] In a preferred but non-limiting embodiment of the present invention, the load control terminal and the nearest collection station are both computers.

[0077] The beneficial effects of the present invention are that, compared with the prior art, the technical effects of the present invention include:

[0078] The load control terminal performs segmented processing on the load control information based on the identified format information, and then transmits it to the nearest collection station through the transmission pipeline PIPE. The nearest collection station analyzes the information and returns the identification header to the load control terminal. The load control terminal removes the information on the transmission pipeline PIPE after receiving the identification header. This method ensures that the information can be transmitted completely in scenarios with small bandwidth and unstable communication channels.
