[0003] As for the land management in towns based on GIS, the commonly used method at present is the method mentioned in the patent publication number "CN111639707B", which is to manage the land in towns based on GIS. Specifically, the GIS system is connected to the management terminal through communication. The GIS system is used to collect GIS data of the monitoring area of ​​the town and transmit it to the management terminal. The management terminal is used to obtain multiple land information based on the collected GIS data, so as to obtain data to be analyzed; the data to be analyzed is analyzed to obtain land analysis results, and control instructions are generated based on the land analysis results. In this way, the purpose of land management in towns based on GIS is achieved.

[0004] However, if there is a problem with the architecture between the GIS system and the management terminal, data transmission will often be hindered, which is not conducive to the effectiveness of land management in towns based on GIS. Summary of the invention

[0005] In order to solve the defects in the prior art, the present invention provides a GIS three-dimensional town management system, which can accurately lock the transmission channel where the transmission obstacle occurs, and verify the identification conclusion. It uses 4 transmission channels to execute in a transmission sequence, which can effectively prevent the accumulation of obstacle performance and is suitable for accurate identification of obstacle conditions. Based on this, the stability and credibility of the transmission channel can be continuously ensured, thereby ensuring the correct and stable transmission and control of GIS data, and improving the effect of land management of towns based on GIS.

[0006] The present invention uses the following technical solutions.

[0007] A GIS three-dimensional town management method, comprising:

[0008] The GIS system collects GIS data of the monitoring area of ​​the town and transmits it to the management terminal. The management terminal obtains multiple land information based on the collected GIS data to obtain the data to be analyzed; the data to be analyzed is analyzed to obtain the land analysis results, and control instructions are generated based on the land analysis results. In this way, the purpose of managing the town's land based on GIS is achieved. The GIS system and the management terminal use transmission channels to transmit GIS data;

[0009] When the GIS system transmits GIS data to the management terminal, it includes:

[0010] Step 1: Determine the number of flexible transmission channels according to the transmission requirements;

[0011] Step 2: Define the conversion frequency, use the additional transmission channel for GIS data transmission according to the conversion frequency, and extract 4P transmission channels from the transmission channels still in use as additional transmission channels;

[0012] Step 3: Verification service interface 1 is set at the two corresponding ends of the transmission channel, that is, in one of the GIS system and the management terminal, and verification service interface 2 is set in the other, and the newly recognized additional transmission channel is transformed into verification service interface 1 and verification service interface 2 are communicated and connected, so as to use verification service interface 1 and verification service interface 2 to perform credibility verification on the additional transmission channel;

[0013] Step 4: If the verification is up to standard, the GIS data will be transmitted. If the verification is not up to standard, the transmission channel that does not meet the standard will be replaced with the backup channel.

[0014] Preferably, the number of mobile channels=the number of transmission channels required by the transmission requirement+the number of additional channels, and the number of additional transmission channels=4P, where P is a natural number.

[0015] Preferably, the number of transmission channels required by the transmission requirement is the minimum number of transmission channels that can meet the current transmission requirement.

[0016] Preferably, the additional transmission channels are a set number of transmission channels that are additionally reserved when the transmission requirements are met.

[0017] Preferably, step 2 specifically includes: using the current additional transmission channels for GIS data transmission, and selecting 4P transmission channels previously in use to stop transmitting GIS data, and using the selected 4N transmission channels as additional transmission channels of a new cluster.

[0018] Preferably, in step 3, the credibility verification method includes:

[0019] Step 3-1: Divide the additional transport channels into P clusters. In the same cluster, verify that service interface 2 identifies the transport sequence of the four transport channels.

[0020] Step 3-2: Verify that service interface 1 transmits multiple detection messages through the first transmission channel (channel 1) over verification service interface 2 in accordance with the transmission sequence. The message header of the detection message carries identification code 1, and the message tail carries identification code 2. According to the transmission sequence of the detection message, the identification code 1 of the subsequent adjacent detection message is the same as the identification code 2 of the previous adjacent detection message.

[0021] Preferably, in step 3, the credibility verification method further includes:

[0022] Step 3-3: Verify that the second service interface performs copy caching on each detection message according to the sequence of receiving the detection messages, and connects the message header of the subsequent adjacent detection message with the message tail of the previous adjacent detection message to form a combined message. If the identification code 1 of the subsequent adjacent detection message is the same as the identification code 2 of the previous adjacent detection message, the pair of detection messages is connected, otherwise the connection is terminated.

[0023] Step 3-4: Verification service interface 2 transmits the combined message to verification service interface 1 via the second transmission channel according to the transmission sequence.

[0024] Preferably, in step 3, the credibility verification method further includes:

[0025] Step 3-5: If the header of the combined message received by the verification service interface 1 contains the missing detection message, the verification fails.

[0026] If the combined message received by the verification service interface 1 contains the missing detection message, the verification fails.

[0027] Step 3-6: After receiving the combined message, the verification service interface 2 performs verification on each detection message in the combined message according to the detection message in the copy cache in step 3-3, and selects the detection message in which the identification code 1 and the identification code 2 in the combined message do not correspond in full. The verification service interface 2 corrects the identification code 1 of the detection message in which the identification code 1 and the identification code 2 do not correspond in full to the same data as the copy cache.

[0028] Step 3-7: Verification service interface 2 transmits the corrected combined message to verification service interface 1 via the fourth transmission channel according to the transmission sequence. Verification service interface 1 compares the combined message corrected in step 3-5 with the combined message received this time, and extracts identification code 1 and identification code 2 of the different detection messages in the combined message received this time. The detection message transmitted by verification service interface 1 in step 3-2 corresponding to the extracted identification code 1 and identification code 2 is the detection message.

[0029] Preferably, in step 3, the credibility verification method further includes:

[0030] Step 3-8: Reverse the order of the sequence in the transmission sequence and perform credibility verification again according to the new transmission sequence.

[0036] The verification module is used to set a verification service interface 1 in one of the two corresponding ends of the transmission channel, that is, a verification service interface 2 in the other end of the GIS system and the management terminal, and transform the newly recognized additional transmission channel into a communication connection between the verification service interface 1 and the verification service interface 2, so as to perform credibility verification on the additional transmission channel using the verification service interface 1 and the verification service interface 2;

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Figure 1 It is a partial flow chart of the GIS three-dimensional town management method described in the present invention;

[0040] Figure 2 It is a schematic diagram of the module structure of the GIS three-dimensional town management system described in the present invention. DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely expressed in combination with the drawings in the embodiments of the present invention. The embodiments expressed in this application are only embodiments of a part of the present invention, not all embodiments. According to the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0042] like Figure 1 As shown, a GIS three-dimensional town management method according to the present invention comprises:

[0043] The GIS system collects GIS data of the monitored area of ​​the town and transmits it to the management terminal. The management terminal obtains multiple land information based on the collected GIS data to obtain the data to be analyzed; the data to be analyzed is analyzed to obtain land analysis results, and control instructions are generated based on the land analysis results. In this way, the purpose of managing the town’s land based on GIS is achieved. The GIS system and the management terminal use a transmission channel to transmit GIS data; the management terminal can be a computer.

[0044] When the GIS system transmits GIS data to the management terminal, it includes:

[0045] Step 1: Determine the number of flexible transmission channels according to the transmission requirements;

[0046] In a preferred but non-limiting embodiment of the present invention,

[0047] Number of mobile channels = number of transmission channels required for transmission requirements + number of additional channels,

[0048] The number of additional transmission channels = 4P, where P is a natural number.

[0049] In a preferred but non-limiting embodiment of the present invention, the number of transmission channels required by the transmission requirement is the minimum number of transmission channels that can meet the current transmission requirement. The transmission requirement can be an immediate requirement, an average determined based on usage conditions over a period of time, or a maximum amount determined based on usage conditions over a period of time.

[0050] In a preferred but non-limiting embodiment of the present invention, the additional transmission channels are a set number of transmission channels that are additionally reserved when the transmission requirements are met.

[0051] Step 2: Define the conversion frequency, use the additional transmission channel for GIS data transmission according to the conversion frequency, and extract 4P transmission channels from the transmission channels in use and use them as additional transmission channels again;

[0052] In a preferred but non-limiting embodiment of the present invention, step 2 specifically includes: using the current additional transmission channels for GIS data transmission, and selecting 4P transmission channels from the previously used transmission channels to not transmit GIS data, and using the selected 4N transmission channels as a new cluster of additional transmission channels. That is, the additional transmission channels will also change with the subsequent changes in time points, which is not only suitable for temporary dormancy of the transmission channels, reducing the probability of GIS data delay, but also suitable for performing credibility verification on the transmission channels one by one. Here, the change frequency can be flexibly changed according to specific conditions and requirements.

[0053] Step 3: Set verification business interface 1 at the corresponding ends of the transmission channel, that is, in one of the GIS system and the management terminal, and set verification business interface 2 in the other, and transform the newly recognized additional transmission channel into connecting verification business interface 1 with verification business interface 2, and use verification business interface 1 and verification business interface 2 to perform credibility verification on the additional transmission channel; that is, when performing credibility verification, the channel connection of the additional transmission channel is transformed into connecting verification business interface 1 and verification business interface 2.

[0054] Step 4: If the verification is up to standard, the GIS data will be transmitted. If the verification is not up to standard, the transmission channel that does not meet the standard will be replaced with the backup channel. In this way, it can be ensured that the additional transmission channels are stable and reliable. After the transformation is performed according to the transformation frequency, the stable and reliable transmission channel can bear the GIS data transmission and ensure the correct and stable data transmission. By repeatedly performing steps 1 to 4, the unreliable transmission channels can be continuously replaced, thereby ensuring the correctness and reliability of the entire GIS data transmission.

[0055] In a preferred but non-limiting embodiment of the present invention, in step 3, the method for credibility verification includes:

[0056] Step 3-1: Divide the additional transmission channels into P clusters. In the same cluster, verify that service interface 2 recognizes the transmission sequence of the four transmission channels. For example, taking a cluster of additional transmission channels as an example, the four transmission channels are channel 1, channel 2, channel 3, and channel 4, and the transmission sequence is: channel 1 to channel 2, then to channel 3, and then to channel 4.

[0057] Step 3-2: The verification service interface 1 transmits a plurality of detection messages via the first transmission channel (channel 1) to the verification service interface 2 according to the transmission sequence. The message header of the detection message carries the identification code 1, and the message tail carries the identification code 2. According to the transmission sequence of the detection message, the identification code 1 of the subsequent adjacent detection message is the same as the identification code 2 of the previous adjacent detection message. For example, the verification service interface 2 transmits five detection messages to the verification service interface 2 via channel 1 in sequence. From the first to the last, the identification codes 1 and 2 of the detection messages are: B1 (identification code 1) and B2 (identification code 2), B2 (identification code 1) and B3 (identification code 2), B3 (identification code 1) and B4 (identification code 2), B4 (identification code 1) and B5 (identification code 2), B5 (identification code 1) and B6 (identification code 2). The number of detection messages can be flexibly changed according to specific requirements. This is an exemplary description and should not be used as a specific limitation.

[0058] In a preferred but non-limiting embodiment of the present invention, in step 3, the method for credibility verification further includes:

[0059] Step 3-3: Verify that the second service interface performs copy caching (i.e., copies and stores each detection message) on each detection message according to the sequence of receiving the detection messages, and connects the message header of the subsequent adjacent detection message with the message tail of the previous adjacent detection message to form a combined message. If the identification code 1 of the subsequent adjacent detection message is the same as the identification code 2 of the previous adjacent detection message, the pair of detection messages is connected, otherwise the connection is terminated; just as the sequence of receiving the detection messages by the verification service interface 2 is B1-B2, B2-B3, B3-B4, B4-B5, B5-B6 (all transmitted), the detection messages can be successfully combined as a whole, and the combined message is B1-B2 B2-B3 B3-B4 B4-B5 B5-B6. If the sequence of detection messages received by the second verification service interface is B1-B2, B2-B3, B3-B4, B5-B6, B4-B5 (detection message B4-B5 is delayed in transmission), then the identification code 2 of the third detection message B3-B4 is different from the identification code 1 of the fourth detection message B5-B6. Therefore, the third detection message is connected and then the connection is terminated. The combined message is B1-B2 B2-B3 B3-B4. If the sequence of detection messages received by the second verification service interface is B2-B3, B3-B4, B4-B5, B5-B6 (detection message B1-B2 is lost), then the four detection messages can be successfully connected. The combined message is B2-B3 B3-B4 B4-B5 B5-B6, if the sequence of detection messages received by the verification service interface 2 is B1-B2, B2-B3, B3-B4, B4-B5 (detection messages B5-B6 are missed), then the 4 detection messages can be successfully connected, and the combined message is B1-B2 B2-B3 B3-B4 B4-B5.

[0060] Step 3-4: Verification service interface 2 transmits the combined message to verification service interface 1 via the second transmission channel (channel 2) according to the transmission sequence.

[0061] In a preferred but non-limiting embodiment of the present invention, in step 3, the method for credibility verification further includes:

[0062] Step 3-5: If the header of the combined message received by the verification service interface 1 contains the missing of the detection message, just as the combined message is B1-B2 B2-B3 B3-B4 B4-B5 (the header is missing B5-B6), B2-B3 B3-B4 B4-B5 B5-B6 (the header is missing B1-B2), B3-B4 B4-B5 B5-B6 (the header is missing B1-B2 and B2-B3, etc.), then the verification fails. The occurrence of this missing is often caused by the failure of the first transmission channel (channel one) causing an error in the transmission of the detection message, and is also often caused by the failure of the second transmission channel (channel two) causing the missing of the combined message. It is also often caused by the failure of both the first transmission channel (channel one) and the second transmission channel (channel two). In this case, it means that the first transmission channel (channel one) and the second transmission channel (channel two) corresponding to the transmission sequence often have transmission risks;

[0063] If the combined message received by the verification service interface one contains missing detection messages, such as the combined message is B1-B2 B2-B3 B4-B5 B5-B6 (B3-B4 is missing), B1-B2 B5-B6 (B2-B3, B3-B4, B4-B5 are missing), etc., then the verification fails, and it means that the second transmission channel (channel two) corresponding to the transmission sequence is blocked, and the second transmission channel (channel two) has transmission risks; since the verification service interface two cannot connect and combine the missing combined message, it is only caused by the blockage of the second transmission channel (channel two).

[0064] To verify the accuracy of the fault identification conclusion of the second transmission channel (channel two), take the combined message B1-B2 B2-B3 B4-B5 B5-B6 (B3-B4 is missing) as an example. Verification service interface one corrects the identification code two (B3) of the previous adjacent detection message (that is, B2-B3) of the missing position to be the same as the identification code one (B4) of the subsequent adjacent detection message (that is, B4-B5) of the missing position. The corrected combined message becomes B1-B2 B2-B4 B4-B5 B5-B6 (B3-B4 is missing), that is, the original detection message B2-B3 is corrected to B2-B4. Then, the corrected combined message is transmitted to verification service interface two via the third transmission channel (channel three) according to the transmission sequence.

[0065] Step 3-6: After receiving the combined message, the verification service interface 2 performs verification on each detection message in the combined message according to the detection message copied and cached in step 3-3, and selects the detection message in which the identification code 1 and the identification code 2 in the combined message cannot all correspond. Since A2-A4 was not previously carried, the original verification service interface 2 only stores B2-B3 and B3-B4, and the identification code 1 and the identification code 2 of B2-B4 cannot all correspond. The verification service interface 2 corrects the identification code 1 of the detection message (B2-B4) in which the identification code 1 and the identification code 2 cannot all correspond to the same as the data in the copy cache, that is, to keep the identification code 2 B4 constant, and perform correction on the identification code 1 B2; since the original detection message with the identification code 2 of B4 is B3-B4, B2-B4 is corrected to B3-B4, and the combined message becomes B1-B2 B3-B4 B4-B5 B5-B6;

[0066] Step 3-7: Verification service interface 2 transmits the corrected combined message (B1-B2 B3-B4 B4-B5 B5-B6) to verification service interface 1 via the fourth transmission channel (channel 4) according to the transmission sequence. Verification service interface 1 compares the corrected combined message (B1-B2 B2-B4 B4-B5 B5-B6) in step 3-5 with the combined message (B1-B2 B3-B4B4-B5 B5-B6) received this time, and extracts the combined message (B1-B2 B3-B4 B4-B5 B5-B6) received this time. The extracted detection message sent by the verification service interface 1 corresponding to the extracted identification code 1 and identification code 2 in step 3-2 is the detection message (B3-B4), which is exactly the missing segment in the combined message received by the verification service interface 1 in step 3-5. At the same time, it can be determined that the verification service interface 2 has successfully received the detection message B3-B4 in step 3-3, which also verifies that it is indeed the second transmission channel (channel 2) that has the transmission risk.

[0067] Through this, the transmission channel where the transmission failure occurs can be accurately locked and the identification conclusion can be verified.

[0068] Here, the use of four transmission channels in a transmission sequence can effectively prevent the accumulation of fault performance and facilitate accurate identification of fault conditions.

[0069] In step 3-5, if the combined message received by the verification service interface 1 does not contain any missing detection message, the first and second transmission channel verifications corresponding to the transmission sequence are qualified, and the first and third transmission channel sequences corresponding to the transmission sequence are swapped, and the second and fourth transmission channel sequences corresponding to the transmission sequence are swapped, and the credibility verification is performed again according to the new transmission sequence.

[0070] Therefore, after eliminating the obstacle probability of the first and second transmission channels, the transmission sequence of the third and fourth transmission channels is moved up, which is suitable for performing verification on the third and fourth transmission channels and suitable for performing obstacle verification. The first and second transmission channels that have eliminated the obstacle probability can efficiently ensure the credibility of the verification conclusion.

[0071] In a preferred but non-limiting embodiment of the present invention, in step 3, the method for credibility verification further includes:

[0072] Step 3-8: Reverse the sequence in the transmission sequence and perform credibility verification again according to the new transmission sequence. That is, after executing step 3-7, the transmission sequence is reversed and then steps 3-2 to 3-7 are performed, so that reverse transmission verification of the four transmission channels can be achieved. That is, during this period, the transmission direction of GIS data is reversed in each transmission channel, so forward transmission risks and reverse transmission risks can be screened out.

[0073] like Figure 2 As shown, a GIS three-dimensional town management system according to the present invention comprises:

[0074] The GIS system is connected to the management terminal through communication. The GIS system is used to collect GIS data of the monitoring area of ​​the town and transmit it to the management terminal. The management terminal is used to obtain multiple land information based on the collected GIS data, so as to obtain the data to be analyzed; the data to be analyzed is analyzed to obtain the land analysis results, and the control instructions are generated based on the land analysis results. In this way, the purpose of managing the town's land based on GIS is achieved. The GIS system and the management terminal use a transmission channel to transmit GIS data;

[0075] GIS three-dimensional town management system also includes:

[0076] A determination module, which is used to determine the number of mobile transmission channels according to the transmission requirements;

[0077] A definition module is used to define a conversion frequency, and to use an additional transmission channel for GIS data transmission according to the conversion frequency, and to extract 4P transmission channels from the transmission channels still in use and use them as additional transmission channels again;

[0078] The verification module is used to set a verification service interface 1 in one of the two corresponding ends of the transmission channel, that is, a verification service interface 2 in the other end of the GIS system and the management terminal, and transform the newly recognized additional transmission channel into a communication connection between the verification service interface 1 and the verification service interface 2, so as to perform credibility verification on the additional transmission channel using the verification service interface 1 and the verification service interface 2;

[0079] The transmission module is used to transmit the GIS data if the verification is up to standard, and replace the transmission channel that does not meet the standard with a spare channel if the verification is not up to standard.

[0080] The beneficial effect of the present invention is that, compared with the prior art, the present invention can accurately lock the transmission channel where the transmission obstacle occurs, and verify the identification conclusion. The four transmission channels are used in a transmission sequence, which can effectively prevent the accumulation of obstacle performance and is suitable for accurate identification of obstacle conditions. Therefore, the stability and credibility of the transmission channel can be continuously ensured, thereby ensuring the correct and stable transmission and control of GIS data, and improving the effect of land management of towns based on GIS.

The GIS three-dimensional town management method according to claim 4, characterized in that: Step 2 specifically includes: using the current additional transmission channels for GIS data transmission, and selecting 4P transmission channels from the previously used transmission channels to stop transmitting GIS data, and using the selected 4N transmission channels as the additional transmission channels of a new cluster.

6. The GIS three-dimensional town management method according to claim 5, characterized in that: In step 3, the credibility verification method includes: Step 3-1: Divide the additional transport channels into P clusters. In the same cluster, verify that service interface 2 identifies the transport sequence of the four transport channels. Step 3-2: Verify that service interface 1 transmits multiple detection messages through the first transmission channel (channel 1) over verification service interface 2 in accordance with the transmission sequence. The message header of the detection message carries identification code 1, and the message tail carries identification code 2. According to the transmission sequence of the detection message, the identification code 1 of the subsequent adjacent detection message is the same as the identification code 2 of the previous adjacent detection message.

7. The GIS three-dimensional town management method according to claim 6, characterized in that: In step 3, the credibility verification method further includes: Step 3-3: Verify that the second service interface performs copy caching on each detection message according to the sequence of receiving the detection messages, and connects the message header of the subsequent adjacent detection message with the message tail of the previous adjacent detection message to form a combined message. If the identification code 1 of the subsequent adjacent detection message is the same as the identification code 2 of the previous adjacent detection message, the pair of detection messages is connected, otherwise the connection is terminated. Step 3-4: Verification service interface 2 transmits the combined message to verification service interface 1 via the second transmission channel according to the transmission sequence.

8. The GIS three-dimensional town management method according to claim 7, characterized in that: In step 3, the credibility verification method further includes: Step 3-5: If the header of the combined message received by the verification service interface 1 contains the missing detection message, the verification fails. If the combined message received by the verification service interface 1 contains the missing detection message, the verification fails. Step 3-6: After receiving the combined message, the verification service interface 2 performs verification on each detection message in the combined message according to the detection message in the copy buffer in step 3-3, and selects the detection message in which the identification code 1 and the identification code 2 in the combined message do not completely correspond, and the verification service interface 2 corrects the identification code 1 of the detection message in which the identification code 1 and the identification code 2 do not completely correspond to each other to be the same as the data in the copy buffer; Step 3-7: Verification service interface 2 transmits the corrected combined message to verification service interface 1 via the fourth transmission channel according to the transmission sequence. Verification service interface 1 compares the combined message corrected in step 3-5 with the combined message received this time, and extracts identification code 1 and identification code 2 of the different detection messages in the combined message received this time. The detection message transmitted by verification service interface 1 in step 3-2 corresponding to the extracted identification code 1 and identification code 2 is the detection message.
