According to the embodiment, there is provided a power inspection system based on internet of things and flight communication, the system comprising: the plurality of internet of things edge devices 100, the plurality of power inspection units 200, the communication satellite 300, the master station device 400 and the cloud server 500, wherein the plurality of internet of things edge devices 100 comprise: a small station module 120, and wherein the plurality of internet of things edge devices 100 are communicatively connected with the power inspection unit 200, configured to receive parameter information related to the power devices from the plurality of power inspection units 200; the small station modules 120 in the plurality of internet of things edge devices 100 are in communication connection with the master station device 400 through the communication satellite 300 and are configured to transmit parameter information related to the power devices to the master station device 400 in a time division multiple access manner; and the master station device 400 is connected to the cloud server 500 and configured to transmit parameter information related to the power device to the cloud server 500 based on a message queue telemetry transmission protocol.
As described in the background art, the application level of the modern network technology is gradually improved, the application degree of the network technology is expanded to various fields in social life, the internet of things technology is a novel identification detection technology developed on the basis of the internet information transmission technology, and the application of the internet of things technology in the power equipment inspection can improve the quality of power inspection, can also reduce the working pressure of inspection personnel, and realizes the normal operation of a power industrial application system.
Therefore, at present, the internet of things technology is widely applied to the inspection process of power equipment. The internet of things system comprises a sensor for detecting parameter information of the power equipment and internet of things edge equipment for transmitting the parameter information of the power equipment.
And because the parameter information of the power equipment collected by the edge equipment of the internet of things needs to be transmitted to the cloud server through the internet, the edge equipment of the internet of things is in communication with the cloud server through wired access or through a mobile network.
However, if the parameter information of the power equipment is transmitted to the cloud server by using a wired access mode, the internet of things edge equipment cannot be accessed to the internet by using a wired connection mode in a remote complex field environment; if the parameter information of the power equipment is transmitted to the cloud server by using the mobile communication mode, the internet of things edge equipment cannot be accessed to the internet in a field environment where the mobile network is not covered.
In view of the above, the present disclosure provides a power inspection system based on the internet of things and satellite communication. Fig. 1 is an overall schematic diagram of an electric power inspection system based on internet of things and satellite communication according to an embodiment of the application. Fig. 2 is a schematic block diagram of a power inspection system based on internet of things and satellite communication according to an embodiment of the present application. Fig. 3 is a schematic diagram of a communication transmission link of the power inspection system according to an embodiment of the present application. Referring to fig. 1, 2 and 3, the power inspection system includes a plurality of internet of things edge devices 100, a plurality of power inspection units 200, a communication satellite 300, a master station device 400 and a cloud server 500. The plurality of internet of things edge devices 100 further include a small station module 120.
First, the power inspection unit 200 collects parameter information of the power devices, and transmits the parameter information of the plurality of power devices to the plurality of internet of things edge devices 100 based on the lorewan protocol (i.e., the instant messaging protocol). Each of the plurality of internet of things edge devices 100 may be connected to the plurality of power inspection units 200, and each of the plurality of power inspection units 200 may also be connected to the plurality of power devices. That is, the plurality of power devices, the plurality of power inspection units 200, and the plurality of internet of things edge devices 100 are in fact "star-shaped structures". Thus, the plurality of internet of things edge devices 100 can transmit parameter information of the plurality of power devices to the communication satellite 300.
The small station module 120 in the plurality of internet of things edge devices 100 is then communicatively connected to the communication satellite 300 as a VSAT small station based on the VAST (i.e., time division multiple access) communication standard. That is, in the technical solution of the present disclosure, the plurality of internet of things edge devices 100 are "connection bridges" between internet of things communication and satellite communication. The plurality of internet of things edge devices 100 not only act as an internet of things gateway, receive parameter information of the plurality of electric devices based on the LoraWan protocol, but also act as VSAT small stations, and transmit the parameter information of the plurality of electric devices to the communication satellite 300 in a time division multiple access data frame manner based on the VSAT standard (i.e., a time division multiple access standard). And the parameter information of the plurality of electric devices is transmitted between the plurality of internet of things edge devices 100 and the communication satellite 300 by means of satellite communication, so that the parameter information of the plurality of electric devices is not required to be transmitted to the master station device 400 by means of wired access, and the parameter information of the plurality of electric devices is not required to be transmitted to the master station device 400 by means of mobile communication, and the defect that the parameter information of the plurality of electric devices is transmitted to the master station device 400 by means of wired access and the parameter information of the plurality of electric devices is transmitted to the master station device 400 by means of mobile communication can be effectively avoided.
Further, after the communication satellite 300 transmits the parameter information of the plurality of electric devices to the master station device 400, the master station device 400 acts as a network server of the internet of things, and transmits the parameter information of the plurality of electric devices to the cloud server 500 through the internet based on the MQTT protocol (i.e., message queue telemetry transport protocol). Thus, the transmission of the parameter information of the plurality of electric devices is completed in the above manner.
The power inspection system in the technical scheme of the present disclosure is provided with a communication satellite 300 which is respectively in communication connection with a plurality of internet of things edge devices 100 and a master station device 400. Since the small station modules 120 are disposed in the plurality of internet of things edge devices, when the parameter information of the power device is transmitted to the communication satellite 300, the communication satellite 300 can be used for communicating with the master station device 400 in a time division multiple access manner, and the parameter information of the power device is transmitted to the master station device 400 through the communication satellite 300, so that the parameter information of the power device does not need to be transmitted to the master station device 400 in a wired connection manner, and the parameter information of the power device does not need to be transmitted to the master station device 400 in a mobile communication manner between the plurality of internet of things edge devices and the master station device 400. Therefore, the product structure can transmit the parameter information of the power equipment to the master station equipment 400 in any environment, and further ensure that the master station equipment 400 can normally receive the parameter information of the power equipment. Further, the problem that in the prior art, if the parameter information of the power equipment is transmitted to the cloud server 500 by using a wired connection mode, the internet of things edge equipment cannot be connected to the internet in a remote complex field environment by using the wired connection mode is solved; if the parameter information of the power equipment is transmitted to the cloud server 500 by using the mobile communication method, the internet of things edge equipment cannot be accessed to the internet in a field environment where the mobile network is not covered.
Optionally, the method further comprises: the master station device 400 transmits acknowledgement information indicating that parameter information related to the power device has been received to the plurality of power inspection units 200 through the internet of things edge device 100.
Specifically, referring to fig. 3, the master station device 400, as a network server of the internet of things, generates ACK messages (i.e., ACK messages in fig. 3) corresponding to parameter information of a plurality of power devices after receiving the parameter information of the plurality of power devices based on the LoraWan protocol. And as a VAST master station, transmits the ACK message to the plurality of internet of things edge devices 100 in a TDM manner (i.e., time division multiplexing manner) based on the VAST standard.
Further, according to the standard of the LoraWan protocol, the plurality of internet of things edge devices 100 serve as VSAT small stations, receive the ACK message sent by the master station device 400 through the communication satellite 300, and then the plurality of internet of things edge devices 100 serve as the internet of things gateway to send the ACK message to the terminal processing device 220 in the plurality of internet of things edge devices 100.
Thus, in the Class a mode, after sending out the parameter information of the plurality of power devices, the terminal processing device 220 receives the acknowledgement message of the network server module 420 in the master station device 400 about receiving the parameter information of the plurality of power devices, that is, the ACK message in fig. 3, in the first receiving window after 1s and the second receiving window after 2 s.

The terminal processing device 220 collects parameter information related to the plurality of power devices and transmits the parameter information related to the plurality of power devices to the plurality of internet of things edge devices 100. Therefore, the plurality of internet of things edge devices 100 can receive the parameter information of the plurality of electric devices in the internet of things manner.
Optionally, the terminal processing device 220 includes: an IO interface 221, a terminal processor 222, and a first transceiver 223, wherein the IO interface 221 is connected to the plurality of sensors 210; the terminal processor 222 is connected with the IO interface 221, and is configured to process parameter information of the power device received through the IO interface 221, and generate a first data packet according to the parameter information of the power device, where the first data packet is a data packet of an instant messaging protocol; and a first transceiver 223 coupled to the terminal processor 222 and configured to generate a second data packet based on the internet of things modulation technique.

Then, the MAC layer generates a LoraWAN packet (i.e., a first packet) according to the received parameter information of the plurality of power devices. Specifically, first, the MAC layer generates a frame header of a data frame in the following format. Table 1 shows the frame format of the data frame.

TABLE 4 Table 4
Finally, the first transceiver 223 performs the physical layer and generates a LoRa modulated data packet (i.e., a second data packet). Table 5 shows the data structure of the LoRa modulated data packet.

Specifically, referring to fig. 4, an internet of things network management module 110 is further disposed in the internet of things edge device 100.
First, after the internet of things gateway module 110 receives the LoRa modulated data packet (i.e., the second data packet) transmitted by the terminal processing device 230, it performs an operation of the internet of things gateway based on the LoraWAN standard, and transmits the LoRa modulated data packet (i.e., the second data packet) to the small station module 120.
Then, after receiving the LoRa modulated data packet, the station module 120 performs an operation related to the VSAT station in the VSAT standard, generates a TDME data frame (i.e., a first data frame) according to the LoRa modulated data packet, and then transmits the TDME data frame to the communication satellite 300.
Therefore, the technical effect that the data packet (namely, the second data packet) after the LoRa modulation can be converted into the TDME data frame (namely, the first data frame) containing the parameter information of a plurality of electric equipment is achieved through the product structure.
Optionally, the gateway module 110 of the internet of things includes: a second transceiver 111, a gateway processor 112 and a first communication interface 113, wherein the second transceiver 111 is connected to the first transceiver 223 and is configured to receive the second data packet via the first transceiver 223 and extract the first data packet from the second data packet; the gateway processor 112 is connected to the second transceiver 111 and configured to receive the first data packet; and a first communication interface 113 is coupled to the gateway processor 112 and configured to transmit the first data packet to the small station module 120.

Thus, the cell processor 122 generates a TDMA data frame (i.e., a first data frame) containing the LoRaWAN data packet through the data link control layer.
Fig. 5 is a schematic diagram of the operation of the VSAT system according to an embodiment of the present application. Referring to fig. 5, after the cell processor 122 generates a TDMA data frame (i.e., a first data frame) containing the lowwan data packet through the data link control layer, the TDMA data frame is transmitted to the first FEC modem 122.
