The sensor transmits and monitors the data to the data repeater by the collision detection and the radio frequency hopping technology.
Transmitting the real-time monitoring data processing result back to the data repeater through the radio frequency signal based on the sensor; after the data forwarder preprocesses the monitoring data, the data forwarder packages the processing result data and transmits the processing result data back to the server through a wireless network; the server is used for providing decision support according to the data. Therefore, accurate and effective mass data support is provided for an analysis system, and the functions of branch load data comparison, branch line updating plan, branch peak-valley operation record, line load ratio analysis, zero-sequence fault, non-zero-sequence fault, transient non-fault parameter anomaly analysis and the like have good operation effects.
During assembly, the head part one d10 of the male head d00 moves towards the position of retracting the hollow opening a40 until the supporting sheet b00 is not prevented from entering the hollow opening a30, then the supporting sheet b00 is fed into the hollow opening a30, the male head d00 is released, under the drive of reduction of the helical beryllium bronze wire c00 for return, the head part one d10 of the male head d00 is inserted into the positioning opening b10, the wall one d12 of the male head d00, which maintains an included angle larger than zero in the same horizontal direction, and the wall one b12, which maintains an included angle larger than zero in the same horizontal direction, of the positioning opening b10 move cooperatively, so that the server b0 is connected with the metal cooling sheet a00, in addition, under the drive of reduction of the beryllium bronze wire c00 for return, the active interval between the metal cooling sheet a00 and the server b0 can be achieved, the situation that the server b0 is damaged due to the situation of an operator, the server b0 and the return of the server can not be connected with the metal cooling sheet 00, so that the cooling effect is poor. Can also be favorable to avoiding lead screw or retaining member to link to each other and appear rocking not firm after certain cycle, can ensure firm meeting under the not short cycle.
The mode that the data repeater sends the data after the fast Fourier transform to the server, run on the data repeater, the said mode includes the following measures:
a1: the sensor sends the sensed data to the data repeater, and the data repeater receives the data and then obtains the sensed data;
the sensor sends the sensed data to the data repeater, and the data repeater receives the data and then obtains the sensed data;
a2: the method comprises the steps that a plurality of data sensed in a set time period are traversed periodically after the set time period, the same information segment which continuously appears subsequently is determined, the determined same information segment which continuously appears subsequently is processed by a deflate algorithm to reduce the size of the data, and the data are organized again to form initial information;
the set period of time is less than 8s;
at a2, the reducing the size of the data, and reorganizing the data to form initial information, includes:
constructing a first information piece and a second information piece which correspond to the same information segment which continuously appears subsequently, wherein the first information piece is the capacity of the same information segment which continuously appears subsequently, and the second information piece is the information of the position of the first byte of the same information segment which continuously appears subsequently in the data;
replacing the same information segment which continuously appears subsequently with the information piece I and the information piece II in the data so as to obtain the data with reduced size;
establishing a third message piece corresponding to the same subsequent continuously-appearing message segment, wherein the third message piece is used for indicating the position of a head message piece in the data after the size reduction, the head message piece is one of the first message piece and the second message piece, and the other message piece is positioned behind the head message piece;
and packaging the data after the size reduction and the information piece III to organize the data into the initial information, wherein the information piece III is positioned behind the data after the size reduction.
To clarify the above, the following practical examples are given:
the periodic traversal of the plurality of data sensed during the set period of time includes:
“15、16、17、18、19、20、21、16、17、18、19、2022, 24, 15, 17, 16, 18, … ", wherein the pause number represents a value of one byte before, and it can be determined by checking that" 16, 17, 18, 19, 20 "indicated by italics is the same information segment that continues to appear subsequently, and the processing is performed on the same information segment that continues to appear subsequently: namely, a first information piece and a second information piece which correspond to the same information segment which continuously appears subsequently can be constructed, the first information piece is the capacity of the same information segment which continuously appears subsequently, the second information piece is the information of the position of the first byte of the same information segment which continuously appears subsequently in the data, namely the numerical value of the first information piece is five, the numerical value of the first information piece represents the number of bytes of the same information segment which continuously appears subsequently, the numerical value of the second information piece is eight, and the information of the position of the first byte of the same information segment which continuously appears subsequently in the data, namely the numerical value of the first information piece is five "16"the eighth byte is located in the data, so that only one piece of information is required to correctly represent the location of the first byte of the same information segment that continues to appear subsequently in the data, and it is further clarified that only a single mode of identifying a piece of information is given here, and after the guidance of such a mode, for less simple data comprising several pieces of information that continue to appear subsequently and a single piece of information that continues to appear several times, a mode of locating the same information segment that continues to appear subsequently can be identified with another mode, and such a mode obtained after the guidance should not exceed the design of the technical solution. Replacing the same information segment that continues to appear subsequently with the value five and the value eight, and obtaining the data with reduced size: "15, 16, 17, 18, 19, 20, 21, 5, 8, 22, 24, 15, 17, 16, 18, …"; therefore, the positions of the first information sheet and the second information sheet can be replaced with each other, so that the subsequent execution is not hindered; garmentThe server must give the corresponding method for restoring the data by virtue of the association between the positions of the first information piece and the second information piece, and the method is not subject to the scope of the technical scheme and is not described. In addition, a third information piece is constructed, the third information piece is used for representing the position of a header information piece in the data after the size reduction, the header information piece is one of the first information piece and the second information piece, the other information piece is positioned behind the header information piece, in detail, the third information piece is used for representing that the position of the header information piece in the data after the size reduction can be that the first byte of the header information piece is positioned on the number-th byte in the data after the size reduction, so that the value of the third information piece is eight, it is stated that because the actual examples of the third information piece are not large, a single mode for identifying the third information piece is given, and after the guidance of the mode, the simpler data containing a plurality of same information pieces which continue to appear subsequently and a plurality of information pieces which continue to appear subsequently is obtained, the mode of the third information piece can be identified by other modes, and the mode obtained after the suggestion is not beyond the related scope of the technical scheme.
Then packaging the data with reduced size, namely '15, 16, 17, 18, 19, 20, 21, 5, 6, 22, 24, 15, 17, 16, 18, …' and the information piece three with the value of eight to organize the initial information; when the third server receives the initial information and performs data restoration, and when the third server determines the location of the first information piece, it is understood that the information piece immediately following the first information piece is another information piece, not data.
A3: the headend sends an initial message to the server.
According to the method, the sensor sends the sensed data to the data repeater, the data repeater receives the data and then obtains the sensed data, the data repeater periodically traverses the data sensed in the set time period, recognizes the same information segment which continuously appears subsequently, processes the recognized same information segment which continuously appears subsequently to reduce the size of the data, organizes the data again to form initial information, and compared with the data which does not reduce the size of the data on the same information segment which continuously appears subsequently, the size of the information capacity is greatly reduced, so that the capacity transmitted to the server is reduced, the cost is reduced, and the cost is reduced more easily.
In addition, the capacity of the data is not small, the initial data is directly transmitted to the server in the current mode, information blockage of a communication network is formed on one hand, the server acquires the data with the small capacity, resource waste is not small, and realization of other functions is not facilitated, so that the method can greatly reduce the amount of the information transmitted to the server, reduce the blockage and reduce the resource waste of the server, and further enhance the functions of the server.
