[0026] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are 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 creative work are within the scope of protection of this application.

"And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In the text description of the present application, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0028] The technical solution provided by the embodiment of the present application can be adapted to scenarios such as smart substations, new energy, intelligent power distribution and power plants. In the field of power system control, multiple information acquisition controllers are usually required to communicate with the main information processing controller to report the power data of the power equipment collected by them to the main information processing controller. However, the existing wireless communication methods cannot meet the real-time requirements of delay-sensitive services such as power protection and process control.

[0029] In order to meet the real-time requirements of delay-sensitive services such as power protection and process control, the embodiment of the present application provides a wireless real-time communication system. The wireless real-time communication system provided by the present application will be described in detail through the following specific embodiments. It can be understood that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0030] Figure 1 A schematic diagram of the structure of a wireless real-time communication system provided in an embodiment of the present application, for example, see Figure 1 As shown, the wireless real-time communication system may include a main information processing controller and multiple information collection controllers.

[0031] Among them, each information collection controller is used to report message data to the main information processing controller through the corresponding air interface frequency band; wherein different information collection controllers correspond to different air interface frequency bands, and the message data includes power data of the power equipment collected by the information collection controller.

[0032] The main information processing controller is used to simultaneously perform reception operations on each message data and perform frame splicing through different air interface frequency bands within a preset reception period.

[0033] The value of the receiving period can be set according to actual needs.

[0034] For example, the electrical equipment may be a motor, a switch, a light bulb, etc., and may be configured according to actual needs.

[0035] For example, the power data may include current, voltage, electric energy data, etc., which may be set according to actual needs.

[0036] For example, wireless high-speed synchronous communication may be used between the main information processing controller and the information collection controller.

[0037] It can be seen that in the embodiment of the present application, each of the multiple information acquisition controllers is used to report message data to the main information processing controller through its corresponding air interface frequency band; wherein the air interface frequency bands corresponding to different information acquisition controllers are different, and the message data includes the power data of the power equipment collected by the information acquisition controller; the main information processing controller is used to simultaneously perform the receiving operation for each message data and perform framing through the unprovided air interface frequency band within the preset receiving cycle. In this way, multiple information acquisition controllers report message data including power data to the main information processing controller through their own independent air interface frequency bands, and the main information processing controller simultaneously performs the receiving operation for each message data and performs framing through different air interface frequency bands within the preset receiving cycle, so that the communication delay between the two can be controlled within a relatively short time, effectively reducing the communication delay between the two, and meeting the real-time requirements of delay-sensitive services such as power protection and process control. In addition, it can also effectively solve the problem of heavy workload and difficult communication troubleshooting when the main information processing controller and the information acquisition controller are connected through cables.

[0038] Based on the above Figure 1 In the embodiment shown, for example, in the embodiment of the present application, the message data may also include a unique identification code and a verification code of the information acquisition controller, and the format of the message data is: a unique identification code, power data and a verification code, that is, the information acquisition controller can report its unique identification code and verification code together with the power data to the main information processing controller.

[0039] For example, in the embodiment of the present application, the format of the power data includes: the data type of the power data, the data length of the power data, and the data value of the power data.

[0040] The data type may include a binary bitmap data type, each state occupies 1 bit, and each byte contains 8 bits; the data length may be set according to the number of bytes occupied by the bit.

[0041] When the data value is a character data type, the data length can be fixed at one byte; when the data value is a short integer data type, the data length can be fixed at two bytes; when the data value is an integer data type, the data length can be fixed at four bytes; when the data value is a floating-point data type, the data length can be fixed at four bytes; when the data value is a long integer data type, the data length can be fixed at eight bytes. The specific settings can be made according to actual needs.

[0042] For example, when the message data also includes a unique identification code and a check code of the information collection controller, for example, see Figure 2 As shown, Figure 2 A structural schematic diagram of message data reported by an information acquisition controller provided in an embodiment of the present application, wherein the first two bytes in the message data are the unique identification code of the information acquisition controller, the third byte is the data type, the fourth byte is the data length, the fifth to N+3 bytes are the data values, the third byte to N+3 bytes are the first power data collected, the N+4 byte is the second power data collected, and so on, until the last power data collected, and the last four bytes are the check code.

[0043] The main information processing controller is further used to perform frame splicing based on the reception result after performing the reception operation, including at least the following two possible scenarios: In a possible scenario, the receiving result indicates that message data reported by multiple information collection controllers are all received.

[0044] When the reception result indicates that the message data reported by multiple information collection controllers are all received, for each message data, the message data can be first verified based on the check code in the message data; when the message data passes the verification, the splicing order is determined based on the unique identification code of the information collection controller corresponding to the message data; and based on the splicing order, the power data reported by multiple information collection controllers are spliced. For example, see Figure 3 As shown, Figure 3 A schematic diagram of the structure of target power data obtained by splicing provided in an embodiment of the present application.

[0045] For example, the length of the unique identification code may be 2 bytes by default and pre-configured in the corresponding information collection controller.

[0046] In another possible scenario, the reception result indicates that message data reported by a target information collection controller among the multiple information collection controllers has not been received.

[0047] When the receiving result indicates that there is a message data reported by a target information acquisition controller among multiple information acquisition controllers that has not been received, the message data can be verified based on the check code in the message data for each received message data; when the message data verification passes, the splicing order of the power data in the message data is determined based on the unique identification code of the information acquisition controller corresponding to the message data; for the target information acquisition controller corresponding to the unreceived message data, the pre-configured power data can be determined as the power data reported by the target information acquisition controller, and the splicing order of the pre-configured power data is determined based on the unique identification code of the target information acquisition controller; and based on the splicing order of the power data in each message data and the splicing order of the pre-configured power data, the power data reported by multiple information acquisition controllers are spliced.

[0048] For example, in an embodiment of the present application, the pre-configured power data may be the power data previously reported by the target information acquisition controller, or may be power data filled with bytes of all zero values, etc., and may be specifically set according to actual needs.

[0049] Normally, the power data previously reported by the target information acquisition controller can be determined as pre-configured power data; if there is still no power data reported last time, the power data filled with bytes of all 0 values ​​can be determined as pre-configured power data.

[0050] For example, the length of the power data filled with bytes of all 0 values ​​is consistent with the length of the power data preset by the target information acquisition controller, and the default filling value is 0x00, which can be set according to actual needs.

[0051] Based on any of the above embodiments, when the information acquisition controller is used to report message data to the main information processing controller through the corresponding air interface frequency band, it can first determine the frequency bandwidth used to transmit the message data based on the length of the power data of the message data; and use the bandwidth of the frequency bandwidth in the air interface frequency band to report the message data to the main information processing controller.

[0052] For example, the minimum unit of the frequency bandwidth may be 25 kHz, which may be set according to actual needs.

[0053] In this way, the information acquisition controller uses the bandwidth of the frequency band width in an independent air interface frequency band to report message data to the main information processing controller, thereby improving the real-time performance of power data reporting and realizing full-duplex communication between the main information processing controller and the information acquisition controller. The main information processing controller can simultaneously perform receiving operations for each message data and perform frame splicing through different air interface frequency bands, and the communication delay between the two can be controlled within a relatively short time, effectively reducing the communication delay between the two and meeting the real-time requirements of delay-sensitive services such as power protection and process control.

[0054] Based on any of the above embodiments, for example, in an embodiment of the present application, the main information processing controller is also used to send control messages to multiple information acquisition controllers; correspondingly, each information acquisition controller is also used to control its corresponding power equipment to perform corresponding control operations based on the received control messages, thereby realizing automated control of the power equipment.

[0055] By way of example, in an embodiment of the present application, the main information processing controller is also used to send control messages to multiple information acquisition controllers. It can first determine the sending method of the control messages based on the number of multiple information acquisition controllers; wherein, when the number of multiple information acquisition controllers is greater than a preset number threshold, the sending method is a group sending method, and when the number of multiple information acquisition controllers is less than or equal to the preset number threshold, the sending method is a broadcast method; and based on the sending method, control messages are sent to multiple information acquisition controllers.

[0056] The value of the preset quantity threshold can be set according to actual needs. For example, in the embodiment of the present application, the preset quantity threshold can be 32.

[0057] Taking the preset quantity threshold of 32 as an example, when the number of multiple information acquisition controllers is less than or equal to 32, control messages can be sent to multiple information acquisition controllers by broadcasting; when the number of multiple information acquisition controllers is greater than 32, control messages can be sent to multiple information acquisition controllers by sending.

[0058] For example, in an embodiment of the present application, when the main information processing controller sends control messages to multiple information acquisition controllers by means of a sending method, the multiple information acquisition controllers can be first grouped based on the unique identification codes of the multiple information acquisition controllers to obtain multiple groups; and the control messages corresponding to the groups can be sent to the information acquisition controllers in each group.

[0059] When grouping multiple information acquisition controllers based on the unique identification codes of multiple information acquisition controllers, the number of designated information acquisition controllers contained in each frame of control message can be combined for grouping. Assuming that there are 38 information acquisition controllers, and the number of designated information acquisition controllers contained in each frame of control message is 32, the multiple information acquisition controllers can be sorted and grouped according to the size of the unique identification codes, and the information acquisition controllers corresponding to the first 32 unique identification codes are determined as a group, and the first frame of control message can be sent to the group, and the first frame of message contains the control messages of 32 information acquisition controllers; the information acquisition controllers corresponding to the other 6 unique identification codes are determined as another group, and the second frame of control message can be sent to the group, and the second frame of message contains the control messages of 6 information acquisition controllers. In this way, control messages can be sent to 38 information acquisition controllers in a grouped manner, thereby realizing automatic control of the 38 information acquisition controllers.

[0060] Based on any of the above embodiments, for example, in the embodiment of the present application, the wireless real-time communication system further includes a slave information processing controller, which can be combined with the above Figure 1 As shown, the slave information processing controller and the master information processing controller can use high-speed communication to perform real-time information synchronization.

[0061] Among them, the slave information processing controller is used to serve as a new master information processor when the master information processing controller is in an abnormal state, and is used to execute relevant operations of the master information processing controller. In this way, the stability of the wireless real-time communication system can be guaranteed even when the master information processing controller is in an abnormal state.

[0062] For example, the master information processing controller and the slave information processing controller may be deployed at the same physical location, and use a high-speed communication method to perform real-time information synchronization, which may be a wired method or a wireless method.

[0063] Normally, at the same time, only the main information processing controller communicates with the information acquisition controller, and the communication delay between the two can be controlled within 1ms, meeting the real-time requirements of real-time data transmission and processing. In this way, when the main information processing controller is in an abnormal state, the master-slave switching can be performed, and the slave information processing controller can be used as the new main information processor to execute related operations of the main information processing controller, which can effectively ensure the stability of the wireless real-time communication system.
