Detailed Description
The technical scheme of the invention is further described in detail through the following specific embodiments.
Example 1
The embodiment provides a power line sequence analysis method, as shown in fig. 1, applied to an analysis slave, where the analysis slave corresponds to an analysis master, respectively operates at two ends of a group of power lines, and is respectively connected with the group of power lines, and includes:
step 1, obtaining the number M of the power lines of the group of power lines.
In the specific implementation, the number of the power lines can be preset and analyzed through program solidification, a keyboard or a communication mode, then whether the number of the power lines is larger than a power line number threshold value is judged, and if not, the step 2 is carried out; otherwise, the new number of power lines is re-acquired, so that the situation that the number is not necessarily misjudged as a broken line is prevented, the consistency of an output result and an analysis power line is ensured, for example, only 10 power lines can be connected between an actual analysis host computer and an analysis slave computer, the number of the analysis power lines is preset to be 11 through program solidification, a keyboard or a communication mode, even if the 10 power lines work normally, the content corresponding to one power line in a data matrix filled according to received carrier data is 0, and the misjudgment as the broken line is caused.
Step 2, after receiving the carrier data sent by the analysis host, arranging the carrier data according to a receiving sequence to form an N.times.M data matrix; the carrier data comprises N data, wherein at least one data is a power line number, and N is the maximum abnormal short circuit number of the host side.
In specific implementation, the carrier data is generated and sent by an analysis host; as shown in fig. 2, the carrier data generation steps are as follows:
the number of power lines to be analyzed is obtained, and each power line is sequentially allocated with a number from 1.
Similarly, in the implementation, the number of the power lines can be preset and analyzed through program solidification, a keyboard or a communication mode, then whether the number of the power lines is larger than a power line number threshold value is judged, and if not, a number is further allocated to each power line.
After receiving an analysis start instruction, detecting whether a short circuit condition exists in a power line of an analysis host side by sequentially sending a self-checking signal mode, and if the short circuit condition exists, for example, 2 and 3 short circuits exist, namely, the maximum abnormal short circuit quantity of the host side is 2, generating carrier data comprising 2 elements, specifically, attaching the number data of the short circuit wire to the number data of the power line to form the carrier data; if the short circuit condition does not exist, carrier data comprising 2 elements is generated, and at the moment, the carrier data oil power line number data and 0 are formed. And then, according to the power line number sequence, sending the carrier data corresponding to different power lines to the analysis slave machine through a power line carrier communication mode.
The problem of data disorder caused by the short circuit condition of the analysis host side can be prevented by detecting whether the short circuit condition exists in the power cable of the analysis host side; in addition, the analysis host inserts the power line number which is short-circuited with the analysis host into carrier data and sends the carrier data to the analysis slave, so that the problem that the analysis slave cannot analyze the short-circuited condition of the analysis host side can be solved.
Specifically, the data matrix includes n×m elements, where N is the number of abnormal connection conditions on the host side, and M is the number of power lines of the set of power lines. But because the carrier data is either a power line number or a power line number and corresponding shorting line number data. Therefore, after the carrier data sent by the analysis host is received, the analysis slave places the received carrier data according to the receiving sequence, and fills the carrier data with empty elements after the data is received, so as to form a data matrix comprising N x M elements. Reference is made in particular to the following table.
Assuming that the number of power lines to be analyzed is 6, if the line number 4 and the line number 5 of the host side are short-circuited, the carrier data sequentially sent by the host side are: (1, 0), (2, 0), (3, 0), (4, 5), (5, 4), (6, 0); wherein, (1, 0) is carrier data transmitted through the power line 1, (2, 0) is carrier data transmitted through the power line 2, (3, 0) is carrier data transmitted through the power line 3, (4, 5) is carrier data transmitted through the power line 4, (5, 4) is carrier data transmitted through the power line 5, and (6, 0) is carrier data transmitted through the power line 6.
The carrier data sequentially received from the machine side are (1, 0), (2, 0), (3, 0), (4, 5), (5, 4), (6, 0); wherein, (1, 0) is carrier data received through the power line 1, (2, 0) is carrier data received through the power line 2, (3, 0) is carrier data received through the power line 3, (4, 5) is first carrier data received through the power line 4, and (6, 0) is carrier data received through the power line 6.
It should be noted that, because the short circuit condition occurs on the incoming line side of the power line 4 and the power line 5, the incoming line side and the outgoing line side of the power line 5 are disconnected, and the outgoing line side of the power line 5 cannot receive carrier data;
therefore, when monitoring the carrier data, if any power line does not receive the carrier data within a period of time, whether the carrier data is received is required to be judged, specifically, whether the carrier data is received is judged according to whether the recorded carrier data is equal to the number M of the power lines, if the recorded carrier data is equal to the number M of the power lines, the carrier data is judged to be received, and if the recorded carrier data is not equal to the number M of the power lines, the carrier data is judged to be received;
when the carrier data is not received completely, triggering a communication timeout mechanism, wherein the maximum timeout time= (M-i) t, i is the number of the recorded carrier data, t is 1/transmission baud rate, and when the timeout time exceeds (M-i) t, the carrier data is not received yet, and the reception is judged completely, the monitoring of the carrier data is stopped, and 0 is used for supplementing, so that a data matrix of N x M elements is formed.
The resulting data matrix comprises 2*6 elements in the following specific form:
| 1 | 0 |
| 2 | 0 |
| 3 | 0 |
| 4 | 5 |
| 6 | 0 |
| 0 | 0 |
after the carrier data is received, searching a data matrix by using a breadth-first algorithm to calculate the wiring state of the power line, and sending the wiring state to an analysis host; and finishing the single analysis, and waiting for acquiring the number of new power lines to be analyzed.
Specifically, the step of searching the data matrix by using the breadth-first algorithm to calculate the wiring state of the power line is as follows:
performing a lateral search and a longitudinal search on each element using a breadth-first search model starting from the first element of the data matrix:
if the transverse search finds that other non-zero elements exist, marking the power line numbers corresponding to the elements and all the non-zero elements as a short circuit at the host side;
if the longitudinal search finds the element identical to the element, marking the element and the power line numbers corresponding to all the elements identical to the element as a slave side short circuit;
if the element which is the same as the element is not found in the longitudinal search, marking the power line label information corresponding to the element as normal wiring;
after the transverse search and the longitudinal search of all elements of the data matrix are completed, judging whether a power line number does not exist, if not, judging that the power line number is disconnected, and marking the power line number as disconnected.
Further, when the elements are searched transversely and longitudinally, the marked power line numbers are skipped and no search is performed any more; therefore, the resource expense of the processor can be effectively saved, the searching speed and efficiency are improved, and even on low-power-consumption processors such as a singlechip and the like, the line sequence result can be rapidly obtained, so that the searching efficiency is greatly improved; the method is more obvious especially when the number of the power lines is large and meanwhile, the fault connection, the disconnection and the short circuit exist, so that the time for operators to wait for results is effectively shortened, and the working efficiency is improved.
Furthermore, after the analysis slave machine calculates the wiring state of the power line, the analysis result can be visually displayed by using a mode of upper computer communication or screen display according to the field condition, so that the efficiency and the accuracy of the analysis process are improved.
Meanwhile, after the analysis slave machine calculates the wiring state of the power line, the calculated wiring state of the power line can be sent to the analysis host machine through a carrier signal, so that the analysis host machine synchronously displays the result, the analysis result is confirmed for the second time through a program, and the testing personnel at the two ends of the master and slave can conveniently check the wiring situation in time under the remote test.
Example 2
This embodiment gives a specific example.
In this embodiment, a wiring process inspection is performed on 10 power lines in the three-phase four-wire low-voltage metering cabinet, wherein the power line 2 and the power line 3 have a short circuit condition on the wire inlet side, and meanwhile, the wire inlet and the wire outlet of the power line 3 are disconnected, the wire inlet and the wire outlet of the power line 6 are disconnected, the power line 9 and the power line 10 are short-circuited on the wire outlet side, and meanwhile, the wire inlet and the wire outlet of the power line 9 are disconnected, as shown in fig. 3.
And (3) leading the analytic host to be connected with the measuring point, leading the analytic slave to be connected with the measuring point, and clicking to start detection after the number of the input measuring lines M=10, wherein the specific detection process is as follows:
the analysis host firstly judges that the short circuit condition exists on the analysis host side, namely the incoming line side, through self-checking, the short circuit power lines are 2 and 3, the information is recorded in an abnormal condition buffer zone, the data length n=2, and the number of abnormal wires is the number of abnormal wires;
after the analysis host side checks, carrier data is transmitted sequentially from the power line 1 through the power line carrier.
In a first preset period, the carrier data transmitted by the power line 1 is (1, 0); after the slave receives the carrier data (1, 0) transmitted by the power line 1, the carrier data (1, 0) is arranged in the first row.
In the second preset period, the carrier data sent by the power line 2 is (2, 3), and after the slave receives the carrier data (2, 3) sent by the power line 2, the carrier data (2, 3) are arranged in the second row.
In the third preset period, the carrier data sent by the power line 3 is (3, 2), and the analysis slave machine does not receive the received carrier data (3, 2) through the power line 3 because the incoming line and the outgoing line of the power line 3 are disconnected, a timeout mechanism is started, when the disconnection timeout time is less than (10-2) t, the carrier data received by the power line 3 is continuously recorded, and when the timeout time is greater than (10-2) t, the recording of the carrier data received by the power line 3 is stopped.
In a fourth preset period, the carrier data transmitted by the power line 4 is (4, 0); after the slave receives the carrier data (4, 0) transmitted by the power line 4, the carrier data (4, 0) is arranged in the third row.
In the fifth preset period, the carrier data sent by the power line 5 is (5, 0), and after the slave receives the carrier data (5, 0) sent by the power line 5, the carrier data (5, 0) is arranged in the fourth row.
In the sixth preset period, the carrier data sent by the power line 6 is (6, 0), and the analysis slave does not receive the carrier data (5, 0) sent by the power line 6 because the power line 6 is broken, and also starts a start timeout mechanism, when the break timeout time is less than (10-4) x t, the carrier data received by the power line 6 is continuously recorded, and when the timeout time is greater than (10-4) x t, the recording of the carrier data received by the power line 6 is stopped.
In the seventh preset period, the carrier data transmitted by the power line 7 is (7, 0); after the slave receives the carrier data (7, 0) transmitted by the power line 7, the carrier data (7, 0) is arranged in the fifth row.
In the eighth preset period, the carrier data transmitted by the power line 8 is (8, 0), and after the slave receives the carrier data (8, 0) transmitted by the power line 8, the carrier data (8, 0) is arranged in the sixth row.
In the ninth preset period, the carrier data sent by the power line 9 is (9, 0), and because the power line 9 and the power line 10 are short-circuited at the outgoing line side, the incoming line and the outgoing line of the power line 9 are disconnected, so that the analysis slave also starts a timeout mechanism, when the disconnection timeout time is less than (10-6) x t, the carrier data received by the power line 9 is continuously recorded, and when the timeout time is greater than (10-6) x t, the recording of the carrier data received by the power line 9 is stopped.
In the tenth preset period, the carrier data sent by the power line 10 is (10, 0), after the slave receives the carrier data (10, 0) sent by the power line 10, the carrier data (10, 0) is arranged in the seventh row, meanwhile, the power line 9 and the power line 10 are short-circuited on the outgoing line side, so that the outgoing line end of the power line 9 also receives the carrier data (10, 0), the disconnection timeout time is less than (10-6) t, the carrier data received by the power line 9 is recorded, the carrier data (8, 0) is arranged in the eighth row, and the recording of the carrier data received by the power line 9 is stopped.
After all timeout mechanisms are completed, only 8 carrier data are found to be received, and 0 is used for supplementing, and finally a data matrix of 2×10 is formed, as shown in the following table.
| 1 | 0 |
| 2 | 3 |
| 4 | 0 |
| 5 | 0 |
| 7 | 0 |
| 8 | 0 |
| 10 | 0 |
| 10 | 0 |
| 0 | 0 |
| 0 | 0 |
After the data matrix is obtained, the analysis slave machine starts to analyze the wiring condition.
Specifically, the analysis slave machine starts to execute breadth search from the first element of the first row of the data matrix, specifically including transverse search and longitudinal search, and the search results are as follows: if the transverse search does not find that other non-zero elements exist, and the longitudinal search does not find the elements identical to the elements, marking the power line reference numeral 1 corresponding to the elements as normal wiring;
performing breadth search on the first element of the second row, wherein the search result is as follows: the transverse search finds that other non-zero elements 3 except 2 are unexpected, the longitudinal search does not find the elements identical to the elements, and then the situation that the power lines 2 and 3 are short-circuited on the analysis host side is judged, and the power line labels 2 and 3 are marked as the short circuit on the host side;
performing breadth search on the first element of the third line, wherein the search result is as follows: if the transverse search does not find that other non-zero elements exist, and the longitudinal search does not find the elements identical to the elements, marking the power line label 4 corresponding to the elements as normal wiring;
performing breadth search on the first element of the fourth line, wherein the search result is as follows: if the transverse search does not find that other non-zero elements exist, and the longitudinal search does not find the elements identical to the elements, marking the power line label 5 corresponding to the elements as normal wiring;
performing breadth search on the first element of the fifth line, wherein the search result is as follows: if the transverse search does not find that other non-zero elements exist, and the longitudinal search does not find the elements identical to the elements, marking the power line reference numeral 7 corresponding to the elements as normal wiring;
performing breadth search on the first element of the sixth row, wherein the search result is as follows: if the transverse search does not find that other non-zero elements exist, and the longitudinal search does not find the elements identical to the elements, marking the power line label 8 corresponding to the elements as normal wiring;
performing breadth search on the first element of the seventh row, wherein the search result is: the transverse search does not find that other non-zero elements exist, the longitudinal search finds that the same element as the element exists in the eighth row, and the power line number corresponding to the element is 10, and since the seventh row element and the eighth row element are data received by the power line received by the slave side in the 10 th preset period, the power line 9 and the power line 10 are not judged to be in a misconnection condition, specifically the power line 10 is normal, the power line 9 is shorted with the power line 10 at the slave side, and the power lines 9 and 10 are marked as being shorted at the slave side.
After the search is completed, the power line 6 is marked as open if the power line number 6 is found to be absent.
After the search is finished, the wiring condition is sent back to the analysis host computer through the power line, so that a person can conveniently check the analysis result through the analysis host computer and the analysis slave computer display screen.
It can be seen that, since the slave side in the present application orders the carrier data according to the receiving order, and the power line state is determined according to the number in the carrier data in the later stage, it is possible to avoid the influence of the confusion of the power line arrangement of the slave side and the slave side.
Taking the wiring process inspection of 10 power lines in the three-phase four-wire low-voltage metering cabinet as an example, wherein the power line 7 of the host side is correspondingly connected with the 8 th port of the slave side, and the power line 8 of the host side is correspondingly connected with the 7 th port of the slave side; since the transmission sequence of the host side is from the power line 1 to the power line 10, when the slave side monitors that the 8 th port receives data in the seventh preset period, it can be determined that the eighth port of the slave side is correspondingly connected with the power line 7 of the host side; when the slave side monitors that the seventh port receives data in the eighth preset period, it can be determined that the power line 8 of the master side is correspondingly connected to the seventh port of the slave side.
So that even if the arrangement of the power lines 7 and 8 on the master side and the power lines 7 and 8 on the slave side is disordered, the implementation of the present application is not affected.
