Detailed Description
The following detailed description of embodiments of the invention is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the invention is not limited to the specific embodiments. It will be understood by those skilled in the art that in the present invention, the use of the letters "a", "B", "C", "D" is intended to distinguish between different technical terms, e.g., two terms wireless terminal a and wireless terminal B are intended to indicate that the two are different terminals, but at the same time, wireless terminal a and wireless terminal B may have the same product model.
The power system inspection is a standard operation in the running process of the power plant. Aiming at the requirement of high-quality development, a plurality of power plants, power stations and power system enterprises are provided with automatic inspection methods and systems, and most of the systems rely on meters which automatically collect data and have wireless transmission functions or rely on self-propelled inspection robots to achieve the inspection purpose. In the daily use process, short-range LAN data transmission often encounters some channel fading problems, for example, when some instruments are installed inside metal pieces, the signal transmission distance of the instruments is greatly reduced, for example, when the inspection robot travels to some positions, the signal transmission of the inspection robot is greatly blocked, and at the moment, the signal transmission distance of the inspection robot is also greatly reduced.
FIG. 1 is a flow chart of a method according to an embodiment of the invention. As shown in the figure, the method for transmitting the monitoring and management information of the power system based on the Internet of things technology comprises the following steps:
step 11: the wireless terminal A sends a resource request message A to the wireless terminal B; in one embodiment, the resource request message a may include an amount of resources required by the wireless terminal a for the wireless terminal a to transmit data, and in one embodiment, if the wireless terminal a is able to monitor the reference signal transmitted by the power system center server, the resource request message a may include a signal quality of the reference signal monitored by the wireless terminal a; it should be understood by those skilled in the art that in the resource request message a, information of the amount of resources required for the wireless terminal a to transmit data and the signal quality of the reference signal, which are required by the wireless terminal a, is a payload portion of the resource request message a;
step 12: after receiving the resource request message a, the wireless terminal B simultaneously transmits an updated version of the resource request message a and the resource request message B to the power system center server, wherein the updated version of the resource request message a has an identity identifier a and a forwarding identifier, and the resource request message B has an identity identifier B; in one embodiment, the resource request message a sent by wireless terminal a to wireless terminal B includes an identity of wireless terminal a, which may be a device identifier of wireless terminal a, and thus the length of the identifier may be long; in one embodiment, after receiving the resource request message a sent by the wireless terminal a, the wireless terminal B may only establish an association table inside the wireless terminal B to associate the resource request message a with the wireless terminal a, and then, if the wireless terminal B receives the resource allocated for the resource request message a, the wireless terminal B can send the allocated resource to the wireless terminal a based on the association table; in one embodiment, the updated version of the resource request message a includes the payload portion of the resource request message a, and the identifier a may be a short identifier negotiated by the wireless terminal B with the power system central server, for example, in a power system central server controlling 1000 monitoring terminals (the monitoring terminals include smart meters, inspection robots, etc., and the 1000 monitoring terminals include all monitoring terminals such as the wireless terminal a and the wireless terminal B), where the aforementioned identifier a may be a certain random number (the random number length is obviously smaller than the serial number of the device) randomly selected by the wireless terminal B between the ranges (0, 299), there are 1000 terminals, but the reason that the random number is only selected between 0-299 is that there are rarely 1000 terminals that need to send data to the power system central server at the same time, and of course, in other embodiments, the random number may be selected from 0-99,0-199 or 0-49, etc.; in one embodiment, wireless terminal B may decode the resource request message a received from wireless terminal a to determine the payload of the resource request message a, and then wireless terminal B combines the payload of the resource request message a with the identity identifier a and the forwarding identifier into one data packet for transmission to the power system center server. In one embodiment, the forwarding identifier may be represented by a bit in the updated version of the resource request message a, e.g., when the bit is 0, indicating that the updated version of the resource request message a is a forwarded resource request message. It will be appreciated by those skilled in the art that since both identifiers a and B are selected by wireless terminal B, the identifiers a and B should not be the same random number;
step 13: after sending the updated version of the resource request message a and the resource request message B to the power system center server, the wireless terminal B attempts to receive the resource request response message a and the resource request response message B sent by the power system center server, wherein the resource request response message a includes header information a, and the resource request response message B includes header information B; within the current power monitoring framework, one power system center server may control thousands of monitoring terminals, and assuming that one power system center server controls 1000 monitoring terminals, then wireless terminal B and wireless terminal C (wireless terminal C is the third terminal different from wireless terminals a and B) may use identifiers a and B when sending a resource request message, wireless terminal C may randomly select another identifier C, and thus the server only needs to copy the received identifier in the header portion of the resource request response message, and then wireless terminal B and wireless terminal C can determine whether the response message is a message sent to itself according to the header information in the resource request response message;
step 14: after receiving the resource request response message a, the wireless terminal B determines whether header information a included in the resource request response message a carries an identity identifier a;
step 15: if the header information A included in the resource request response message A is determined to carry the identity identifier A, the wireless terminal B continues to determine the resource allocation information A carried in the resource request response message A;
step 16: after determining the resource allocation information A carried in the resource request response message A, the wireless terminal B sends the resource allocation information A to the wireless terminal A; in one embodiment, the resource allocation information a indicates not only time-frequency resources for transmitting data, but also information such as transmission power, modulation and coding scheme, which are payloads of the resource allocation information;
step 17: after receiving the resource allocation information a, the wireless terminal a transmits power system monitoring and management information to the wireless terminal B or the power system center server.
In a preferred embodiment, the method comprises:
after receiving the resource request response message B, the wireless terminal B determines whether the header information B included in the resource request response message B carries an identity identifier B;
if the header information B included in the resource request response message B is determined to carry the identity identifier B, the wireless terminal B continues to determine the resource allocation information B carried in the resource request response message B;
after determining the resource allocation information B carried in the resource request response message B, the wireless terminal B sends power system monitoring and management information to the power system center server on the resource indicated by the resource allocation information B.
Further, the method for transmitting the monitoring and management information of the power system based on the internet of things technology comprises the following steps: after receiving the updated version of the resource request message a, the power system center server configures resource allocation information a based on the forwarding identifier in the updated version of the resource request message a, wherein a time difference of a first time length exists between a time position of the resource indicated by the resource allocation information a and a time position of the updated version of the resource request message a received by the power system center server; in one embodiment, the starting time position of the resource indicated by the resource allocation information a is, for example, time point 1 (the resource necessarily has a certain time span in time, the starting time position of the resource is time point 1, the ending time point may be named as time point 1'), the time position when the power system central server receives the updated version of the resource request message a is, for example, time point 2, then the time difference between time point 1 and time point 2 has a first time length;
after receiving the resource request message B, the power system center server configures resource allocation information B based on the resource request message B, wherein a time difference between a time position of the resource indicated by the resource allocation information B and a time position of the power system center server receiving the resource request message B has a second time length, and wherein the first time length is at least twice as long as the second time length. In one embodiment, the starting time position of the resource indicated by the resource allocation information B is, for example, time point 3, and the time position at which the power system center server receives the resource request message B is, for example, time point 4, then the time difference between time point 3 and time point 4 has a second time length.
Further, the method for transmitting the monitoring and management information of the power system based on the internet of things technology further comprises the following steps: after receiving the resource allocation information a, the wireless terminal a determines whether a reference signal transmitted by the power system center server can be received; if the reference signal sent by the power system center server cannot be received, the wireless terminal A sends power system monitoring and management information to the wireless terminal B; it should be understood by those skilled in the art that the inability of the wireless terminal a to receive the reference signal transmitted by the power system center server means that the wireless terminal a cannot resolve the reference signal from noise with reasonable likelihood, at which point the wireless terminal a considers that it is not listening to the reference signal; after receiving the power system monitoring and management information transmitted by the wireless terminal a, the wireless terminal B transmits the power system monitoring and management information received from the wireless terminal a to the power system center server on the resource indicated by the resource allocation information a.
Example 2
Further, the method for transmitting the monitoring and management information of the power system based on the internet of things technology further comprises the following steps: if the reference signal sent by the power system center server can be received, the wireless terminal A continues to judge whether the receiving quality of the reference signal is larger than a receiving quality threshold; in one embodiment, the receiving quality threshold may be set to a signal-to-noise ratio level, where the signal-to-noise ratio level may be determined based on a data receiving error rate, and in general, the higher the signal-to-noise ratio, the lower the transmission error probability such as a packet loss rate; if the receiving quality of the reference signal is less than the receiving quality threshold, the wireless terminal A sends power system monitoring and management information to the power system center server on the resources indicated by the resource allocation information A, and meanwhile, the wireless terminal A sends power system monitoring and management information to the wireless terminal B; after receiving the power system monitoring and management information transmitted by the wireless terminal a, the wireless terminal B transmits the power system monitoring and management information received from the wireless terminal a to the power system center server on the resources indicated by the resource allocation information a; in one embodiment, wireless terminal B must transmit power system monitoring and management information received from wireless terminal a according to the transmit power, modulation and coding scheme, etc. indicated by the payload in resource allocation information a, whereby the server side receives the identical two sets of data transmitted by wireless terminals a and B, which can facilitate demodulation of the server at the server (considering that the geographical area of the power plant is limited, wireless terminals a and B are necessarily two terminals in close proximity, so that the data phases transmitted to the server by both are almost identical, which, in view of the server side, is equivalent to transmitting some data at double the transmit power, which can facilitate correct decoding of the data by the server); if the receiving quality of the reference signal is judged to be greater than the receiving quality threshold, the wireless terminal A sends power system monitoring and management information to the power system center server on the resources indicated by the resource allocation information A, and meanwhile, the wireless terminal A does not send power system monitoring and management information to the wireless terminal B.
Further, the method for transmitting the monitoring and management information of the power system based on the internet of things technology further comprises the following steps: if the resource request response message A is not received or if the header information A included in the resource request response message A is determined not to carry the identity identifier A, the wireless terminal B resends the updated version of the resource request message A to the power system center server, wherein the updated version of the resource request message A has the identity identifier A and the forwarding identifier; after resending the updated version of the resource request message a to the power system center server, the wireless terminal B attempts to receive a resource request response message C sent by the power system center server, wherein the resource request response message C includes header information C; after receiving the resource request response message C, the wireless terminal B determines whether the header information C included in the resource request response message C carries an identity identifier a; if the header information C included in the resource request response message C is determined to carry the identity identifier A, the wireless terminal B continues to determine the resource allocation information C carried in the resource request response message C; after determining the resource allocation information C carried in the resource request response message C, the wireless terminal B sends the resource allocation information C to the wireless terminal A; after receiving the resource allocation information C, the wireless terminal a transmits power system monitoring and management information to the wireless terminal B or the power system center server.
Further, the method for transmitting the monitoring and management information of the power system based on the internet of things technology further comprises the following steps: after receiving the updated version of the resource request message a again, the power system center server configures resource allocation information C based on the forwarding identifier in the updated version of the resource request message a, wherein a time difference between a time position of the resource indicated by the resource allocation information C and a time position of the updated version of the resource request message a again is provided with a third time length, wherein the third time length is at least twice the second time length.
Example 3

In one embodiment, if the wireless terminal a receives the transmission identifier, the wireless terminal a still determines whether the reference signal transmitted by the power system center server can be received; if the reference signal sent by the power system center server cannot be received, the wireless terminal A sends power system monitoring and management information to the wireless terminal B; if the reference signal transmitted by the power system center server can be received, the wireless terminal a continues to determine whether the reception quality of the reference signal is greater than the reception quality threshold, and even if the wireless terminal a determines that the reception quality of the reference signal is greater than the reception quality threshold, the wireless terminal a transmits the power system monitoring and management information to the wireless terminal B based on the reception of the transmission identifier, and in one embodiment, when the wireless terminal a determines that the reception quality of the reference signal is greater than the reception quality threshold, the wireless terminal a transmits the power system monitoring and management information to the wireless terminal B, and the wireless terminal a simultaneously transmits the redundant identifier to the wireless terminal B.
