Description

Technical Field

[0001] The present disclosure relates to the technical field of map data processing, and in particular to a method for merging warning information with three-dimensional map coordinate information, a two-dimensional map warning display method, and a corresponding system. Background Art

[0002] Displaying warning information on a 3D map is one of the important functions of a 3D map application system. It can intuitively and quickly let monitoring personnel know relevant information when an alarm occurs (for example, high temperature, fire, thick smoke, harmful gases, etc.), so that monitoring personnel can respond in time. At present, some 2D map application system developers hope to be able to receive access to the 3D map application system and receive warning information from the 3D map application system so as to display the warning information on the 2D map.

[0003] In actual applications, it is found that the current three-dimensional map application system and the two-dimensional map application system are configured with a coordinate transmission channel (used to realize the three-dimensional coordinate data transmission from the three-dimensional map application system to the two-dimensional map application system), but there is no warning information transmission channel. Therefore, it is necessary to develop a new data transmission channel (i.e., develop a new interface) between the three-dimensional map application system and the two-dimensional map application system for transmitting warning information. However, due to all the differences in the system framework structure, interface protocol, etc. of different two-dimensional map application systems, when developing a new data transmission channel for transmitting warning information, the manufacturers of each two-dimensional map application system need to carry out various independent adaptation developments, resulting in a large amount of workload and debugging costs.

It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present invention, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined as such herein.

[0060] Figure 1 This is a systematic structural block diagram of the application scenario involved in this disclosure. Figure 1 As shown, the application scenarios involved in the present disclosure include the following two types of independent objects: a three-dimensional map application system and a two-dimensional map application system, wherein the number of the three-dimensional map application system and the two-dimensional map application system can be one or more, and the present disclosure does not limit this.

[0061] In addition, the warning information in the present disclosure is generated by the front-end sensing device, which refers to the sensing device arranged in the real physical space according to the monitoring needs, such as high temperature sensing device (monitoring temperature and generating corresponding warning information when the temperature exceeds the threshold), smoke sensing device (monitoring smoke concentration and generating corresponding warning information when the smoke concentration exceeds the threshold), harmful gas sensing device (monitoring the concentration of harmful gases, such as formaldehyde gas, sulfur dioxide gas, ammonia gas, etc., and generating corresponding warning information when the concentration of harmful gases exceeds the threshold), etc. Among them, the warning information is information used to prompt that the sensing index at the corresponding position exceeds the corresponding preset range, that is, there is an alarm. The warning information generally includes several items of alarm data, which refers to data information used to describe the alarm status, such as alarm code, alarm type, alarm time, alarm severity, etc.

[0062] In the present disclosure, the location, quantity, specific type, etc. of the deployed front-end sensing devices, as well as the specific warning data included in the early warning information, are not limited.

[0063] Figure 2The present invention provides a flowchart of a method for combining early warning information with three-dimensional map coordinate information. Figure 2 As shown, the information merging method includes: applied to a three-dimensional map application system, the information merging method includes:

[0064] Step S101: Acquire warning information generated by the front-end sensing device, and acquire original three-dimensional coordinate information of the three-dimensional coordinate point corresponding to the front-end sensing device in the three-dimensional map.

[0065] The original three-dimensional coordinate information includes: original two-dimensional plane coordinate data and original one-dimensional elevation coordinate data. The original three-dimensional coordinate information can be expressed in coordinate form as (x org ,y org , z org ), the original two-dimensional plane coordinate data can be expressed in coordinate form as (x org ,y org ), x org and org Represents the first dimension coordinate data and the second dimension coordinate data respectively, z org Represents the original one-dimensional elevation coordinate data.

[0066] When a certain front-end sensing device arranged in the real physical space detects an alarm, it will generate corresponding warning information and send the warning information to the three-dimensional map application system. In some embodiments, when the three-dimensional map application system receives the alarm information sent by the front-end sensing device, it will perform data integrity, validity, and real-time verification on the alarm information, and eliminate invalid data, such as expired, unreasonable values, false alarms and other unreasonable data. After the alarm information is verified, the original three-dimensional coordinate information of the three-dimensional coordinate point corresponding to the front-end sensing device that generated the alarm information in the three-dimensional map is determined from the system.

[0067] Step S102: merge the warning information with the original one-dimensional elevation coordinate data, and obtain a corresponding merged information decimal number.

[0068] Step S103: Use the decimal number of the merged information as new one-dimensional elevation coordinate data to replace the original one-dimensional elevation coordinate data in the original three-dimensional coordinate information to obtain new three-dimensional coordinate information.

[0069] Since the one-dimensional elevation coordinate data are all represented by decimal numbers, the warning information and the original one-dimensional elevation coordinate data are merged and processed, and then converted into the merged information decimal number, so that the data format of the merged information is exactly the same as the data format of the one-dimensional elevation coordinate data. Therefore, the merged information decimal number can be directly used as the new one-dimensional elevation coordinate data to replace the original one-dimensional elevation coordinate data in the original three-dimensional coordinate information, and the data format of the obtained new three-dimensional coordinate information is exactly the same as the data format of the original three-dimensional coordinate information. At this time, the new three-dimensional coordinate information not only contains the original three-dimensional coordinate information and the warning information, but also the new three-dimensional coordinate information can be directly transmitted to other two-dimensional map application systems using the existing coordinate transmission channel.

[0070] In the embodiment of the present disclosure, the warning information is merged with the elevation coordinate data of the three-dimensional coordinate points in the three-dimensional map, and the merged information is converted into a decimal number, and then the decimal number of the merged information is used to replace the elevation coordinate data in the original three-dimensional coordinate information to obtain the corresponding new three-dimensional coordinate information; the new three-dimensional coordinate information not only contains the original three-dimensional coordinate information but also carries the warning information; the three-dimensional map application system can transmit the new three-dimensional coordinate information to other two-dimensional map application systems through the existing coordinate transmission channel to realize the transmission of three-dimensional coordinate information and warning information. Therefore, the manufacturers of each two-dimensional map application system do not need to develop an additional separate data transmission channel for the warning information, which can effectively reduce the workload and debugging costs brought about by the demand for obtaining warning information.

[0071] Figure 3 FIG. 1 is a flow chart of an optional implementation method of step S102 in the embodiment of the present disclosure. Figure 3 As shown, in some embodiments, the warning information includes several items of warning data; in this case, step S102 includes:

[0072] Step S1021, converting each warning data and original one-dimensional elevation coordinate data into binary codes with corresponding preset numerical bits.

[0073] A corresponding binary encoding algorithm (such as an encoding algorithm used in a common binary converter) may be designed in advance for each item of alarm data to convert the real value of the corresponding alarm data into a binary code with a corresponding preset number of bits. A corresponding data value-binary encoding correspondence table may be designed in advance for each item of alarm data, and the data value-binary encoding correspondence table records the binary codes corresponding to different data values ​​(the data types may be strings, Chinese characters, numbers, etc.).

[0074] The true value of the one-dimensional elevation coordinate data is generally a decimal number, so the decimal-to-binary conversion process can be used to obtain the binary code corresponding to the one-dimensional elevation coordinate data.

[0075] The specific values ​​of the preset numerical bits of the binary code corresponding to each warning data and the original one-dimensional elevation coordinate data can be pre-designed and adjusted according to actual conditions, and this disclosure does not limit them.

[0076] Step S1022: Arrange and merge the binary codes corresponding to all the alarm data and the binary codes corresponding to the original one-dimensional elevation coordinate data in a preset arrangement order to obtain a merged information binary codeword.

[0077] Step S1023: convert the combined information binary codeword from binary to decimal to obtain a corresponding combined information decimal number.

[0078] In some embodiments, the plurality of items of alarm data include: a plurality of items of alarm description data and alarm level weights pre-configured for the front-end sensing device; wherein the alarm level weights configured for different front-end sensing devices corresponding to the same original two-dimensional plane coordinate data are different.

[0079] The alarm level weight is used to represent the importance (severity) of the alarm, where the more important (serious) the alarm is, the greater the corresponding alarm level weight. The value-taking rules of the alarm level weight, such as how many different values ​​are included and how many specific values ​​are taken, can be pre-designed and adjusted according to actual needs, and this disclosure does not limit it.

[0080] In some embodiments, the plurality of items of alarm description data include at least one of: alarm number, alarm type, and alarm time.

[0081] The following will describe step S102 in conjunction with an example. Take the case where the warning information includes two alarm description data and one alarm level weight, and the two alarm description data are the alarm number and the alarm type, respectively. The preset numerical bits of the binary code corresponding to the alarm number, alarm type, and alarm level weight are all 4 bits, and the preset numerical bits of the binary code corresponding to the original one-dimensional elevation coordinate data are 8 bits.

[0082] As an example, the actual value of the alarm number in the warning information (data type is a string) is "01", the alarm type (data type is Chinese) is "dense smoke warning", the alarm level weight (data type is a decimal number) is "1", and the original three-dimensional coordinate information is "(128,64,160)".

[0083] Assume that the binary encoding results obtained by step S1021 are as follows: the 4-bit binary code "0001" corresponding to the true value "01" of the alarm number, the 4-bit binary code "0001" corresponding to the true value "dense smoke warning" of the alarm type, the 4-bit binary code "0001" corresponding to the true value "1" of the alarm level weight, the 4-bit binary code "10100000" corresponding to the true value "160" of the original one-dimensional elevation coordinate data

[0084] Figure 4 A schematic diagram of merging the binary codes corresponding to all the alarm data and the original one-dimensional elevation coordinate data to obtain a combined information binary codeword in the embodiment of the present disclosure. Figure 4 As shown, in step S1022, assuming that the preset arrangement order of the binary code is from front to back: the binary code corresponding to the alarm number, the binary code corresponding to the alarm type, the binary code corresponding to the alarm level weight, and the binary code of the original one-dimensional elevation coordinate data, then through step S1022, a 20-bit merged information binary code word "00010001000110100000" can be obtained; the binary code "0001" of the 1st to 4th bits of the merged information binary code word represents the alarm number, the binary code "0001" of the 5th to 8th bits represents the alarm type, the binary code "0001" of the 9th to 12th bits represents the alarm level weight, and the binary code "10100000" of the 13th to 20th bits represents the original one-dimensional elevation coordinate data.

[0085] In step S1023, the merged information binary code "00010001000110100000" is converted from binary to decimal to obtain the corresponding merged information decimal number "70048", which is used as the new one-dimensional elevation coordinate data, thereby realizing the merging of the original one-dimensional elevation coordinate data and the warning information.

[0086] In step S103, the original one-dimensional elevation coordinate data "160" in the original three-dimensional coordinate information "(128, 64, 160)" is replaced with "70048" to obtain new three-dimensional coordinate information "(128, 64, 70048)".

[0087] It should be noted that the two-dimensional map application system in the present disclosure adopts the existing display method to display warning information in the three-dimensional map. This part is not the invention point of the present disclosure and will not be elaborated in the present disclosure.

[0088] Figure 5 This is a flow chart of a two-dimensional map warning display method provided by an embodiment of the present disclosure. Figure 5 As shown, the two-dimensional map warning display method is applied to the two-dimensional map application system end, and the two-dimensional map warning display method includes:

[0089] Step S201, obtaining new three-dimensional coordinate information.

[0090] Among them, the new three-dimensional coordinate information includes: the original two-dimensional plane coordinate data of the three-dimensional coordinate point corresponding to the front-end sensing device in the three-dimensional map and a new one-dimensional elevation coordinate data. The new one-dimensional elevation coordinate data is a merged information decimal number. The merged information decimal number is used to represent the information after the warning information generated by the front-end sensing device is merged with the original one-dimensional elevation coordinate data of the three-dimensional coordinate point.

[0091] Step S202: Decode the decimal number of the merged information and obtain at least part of the content of the warning information.

[0092] In step S202, by decoding the decimal number of the combined information, the true value of at least part of the warning data in the warning information can be obtained.

[0093] As an example, the real value of part of the warning data in the warning information can be obtained through step S202.

[0094] As another example, the true values ​​of all warning data in the warning information can be obtained through step S202.

[0095] As another example, the true value of part of the warning data and the true value of the one-dimensional elevation coordinate data in the warning information can be obtained through step S202.

[0096] As another example, the true values ​​of all warning data and the true values ​​of one-dimensional elevation coordinate data in the warning information can be obtained through step S202.

[0097] Step S203: Determine a display scheme corresponding to at least part of the content in the obtained warning information.

[0098] In step S203, a corresponding real solution may be determined based on at least part of the content in the obtained warning information.

[0099] As an example, assume that the obtained warning information includes: the true value of the alarm type and the true value of the alarm level weight; the display scheme includes two parts: 1) determining the display logo shape; 2) determining the display color. In the present disclosure, a warning type-display logo shape correspondence table can be designed in advance for the alarm type, and a level weight-display color correspondence table can be designed for the alarm level weight, wherein the warning type-display logo shape correspondence table records the display logo shapes corresponding to different alarm type values, and the level weight-display color correspondence table records the display logo shapes corresponding to different alarm level weights.

[0100] As an example, the real value of the alarm type is "dense smoke warning", and the real value of the alarm level weight is "1". In step S203, by querying the alarm type-display logo shape correspondence table and the level weight-display color correspondence table, the display logo shape corresponding to the alarm type "dense smoke warning" and the display color corresponding to the alarm level weight "1" can be queried. Thus, the display scheme is determined.

[0101] As an example, the display logo shape corresponding to the alarm type "dense smoke warning" is an inverted triangle ▽, and the display color corresponding to the alarm level weight "1" is red. In this case, the display scheme is a red inverted triangle ▽. When the monitoring personnel see a red inverted triangle somewhere on the two-dimensional map, it means that there is a dense smoke warning at that place and the alarm level weight is 1.

[0102] In actual applications, the corresponding rules between different warning information and display plans can be set in advance according to actual needs. In step S203, the rules are matched according to at least part of the content in the warning information obtained in step S202 to determine the display plan, which can reflect at least part of the content of the warning information.

[0103] Step S204: display the original two-dimensional plane coordinate data at the corresponding position in the two-dimensional map using a display solution.

[0104] In the embodiment of the present disclosure, the two-dimensional map application system decodes the decimal number of the merged information and obtains at least part of the content in the warning information, and then determines the display scheme corresponding to at least part of the content in the obtained warning information, and finally displays the original two-dimensional plane coordinate data at the corresponding position in the two-dimensional map with the display scheme, thereby realizing the display of the warning information on the two-dimensional map.

[0105] In some embodiments, the combined information decimal number is obtained by converting the combined information binary codeword from binary to decimal by the three-dimensional map application system, and the combined information binary codeword is obtained by arranging and merging the binary codes corresponding to all the alarm data and the binary codes corresponding to the original one-dimensional elevation coordinate data in a preset arrangement order. For details, please refer to the embodiment shown in the above.

[0106] Figure 6 FIG. 2 is a flow chart of an optional implementation method of step S202 in the embodiment of the present disclosure. Figure 6 As shown, step S202 includes:

[0107] Step S2021, convert the decimal number of the merged information into binary number to obtain the corresponding binary codeword of the merged information.

[0108] Step S2022: perform an AND operation on the preset mask and the combined information binary codeword, and obtain a binary code corresponding to at least one item of alarm data according to the AND operation result.

[0109] Step S2023: Decode the binary code of the obtained alarm data to obtain the true value of the alarm data.

[0110] Among them, several items of alarm data include: several items of alarm description data and alarm level weights pre-configured for the front-end sensing device; the alarm level weights configured for different front-end sensing devices corresponding to the same original two-dimensional plane coordinate data are different.

[0111] In some embodiments, the at least one item of alarm data obtained in step S2031 includes: at least one item of alarm description data and an alarm level weight. Further optionally, the plurality of items of alarm description data include: at least one of an alarm number, an alarm type, and an alarm time.

[0112] Still taking the case where the warning information includes two alarm description data and one alarm level weight, and the two alarm description data are the alarm number and the alarm type respectively, the preset numerical bits of the binary code corresponding to the alarm number, alarm type, and alarm level weight are all 4 bits, and the preset numerical bits of the binary code corresponding to the original one-dimensional elevation coordinate data are 8 bits.

[0113] Assume that the two-dimensional map application system receives new three-dimensional coordinate information "(128,64,70048)". At this time, the original two-dimensional plane coordinate data is (128,64) and the new one-dimensional elevation coordinate data is "70048".

[0114] By converting the combined information decimal number "70048" into binary, a combined information binary code word "00010001000110100000" with a numerical position of 20 bits is obtained.

[0115] As an example, when only the police incident number needs to be obtained, the binary code corresponding to the police incident number is the 1st to 4th bits in the combined information binary codeword. At this time, a preset mask "111100000000000000000" can be designed in advance for extracting the police incident number, that is, a total of 20 bits, and the first 4 bits are all 1, and the last 16 bits are all 0. By performing an AND operation with the combined information binary codeword "00010001000110100000", the AND operation result is "00010000000000000000", and then extracting the first 4 bits of the code "0001", it can be determined that the binary code of the police incident number is "0001", and then by binary decoding "0001" (for example, decoding using a binary decoder corresponding to the police incident number or a pre-designed correspondence table), the police incident number corresponding to "0001" is "01".

[0116] As another example, when only the alarm type needs to be obtained, the binary code corresponding to the alarm type is the 5th to 8th bits in the combined information binary codeword. At this time, a preset mask "00001111000000000000" can be designed in advance for extracting the alarm type, totaling 20 bits, and the 5th to 8th bits are all 1, and the other 16 bits are all 0. By performing an AND operation with the combined information binary codeword "00010001000110100000", the AND operation result is "00000001000000000000", and then extracting the 5th to 8th bit code "0001", it can be determined that the binary code of the alarm type is "0001", and then by binary decoding "0001" (for example, decoding using a binary decoder corresponding to the alarm type or a pre-designed correspondence table), the alarm type corresponding to "0001" is obtained as "dense smoke warning".

[0117] That is to say, when the number of bits of the preset mask is the same as the number of bits of the binary codeword of the merged information, the corresponding preset mask can be designed according to the alarm data and the original one-dimensional elevation coordinate data required by the two-dimensional map application system. That is, in the 20-bit preset mask, the positions corresponding to the alarm data or the original one-dimensional elevation coordinate data that need to be extracted are all set to 1, and the positions corresponding to the alarm data or the original one-dimensional elevation coordinate data that do not need to be extracted are all set to 0.

[0118] As a case, the two-dimensional map application system needs to extract all the alarm data and the original one-dimensional elevation coordinate data (generally, the two-dimensional map application system does not need the elevation coordinate data). At this time, the preset mask can be pre-designed as "1111111111111111111111", and the AND operation is performed with the merged information binary code word "00010001000110100000", and the AND operation result is "00010001000110100000", and then according to the merged information binary code word encoding rule, it can be concluded that the binary code "0001" of the 1st to 4th bits in the merged information binary code word represents the alarm number, the binary code "0001" of the 5th to 8th bits represents the alarm type, the binary code "0001" of the 9th to 12th bits represents the alarm level weight, and the binary code "10100000" of the 13th to 20th bits represents the original one-dimensional elevation coordinate data.

[0119] Then, according to the binary coding rules of each alarm data and the original one-dimensional elevation coordinate data, the binary codes of each alarm data and the original one-dimensional elevation coordinate data are decoded to obtain the true value corresponding to the 4-bit binary code "0001" of the alarm number is "01", the true value corresponding to the 4-bit binary code "0001" of the alarm type is "dense smoke warning", the true value corresponding to the 4-bit binary code "0001" of the alarm level weight is "1", and the true value corresponding to the 8-bit binary code "10100000" of the original one-dimensional elevation coordinate data is "160".

[0120] It should be noted that in the present disclosure, a preset mask is used to extract the information required by the two-dimensional map application system, which can realize on-demand extraction of the two-dimensional map application system on the one hand, and effectively protect the merged information on the other hand.

[0121] In actual applications, it is found that due to the existence of elevation coordinates in three-dimensional maps, the same original two-dimensional plane coordinate data will correspond to multiple front-end sensing devices, and different warning information will correspond to the same original two-dimensional plane coordinate data. For example, a multi-story building is equipped with a corresponding smoke sensing device on each floor. The two-dimensional plane coordinate data of the three-dimensional coordinate points corresponding to these smoke sensing devices in the three-dimensional map are the same, but the one-dimensional elevation coordinates are different. In the two-dimensional map, since the one-dimensional elevation coordinates are removed, these different smoke sensing devices located on different floors of the same multi-story building will correspond to the same two-dimensional plane coordinate data. At this time, when the warning information is displayed in the two-dimensional map, multiple warning information will be stacked and displayed at the same position (that is, the position represented by the corresponding same two-dimensional plane coordinate data), affecting the monitoring personnel's viewing of the warning information. In order to effectively improve the above technical problems, the present disclosure provides corresponding solutions.

[0122] Figure 7 FIG. 1 is a schematic diagram of using the alarm level weight to display the warning information in a dispersed manner in the embodiment of the present disclosure. Figure 7 As shown, in some embodiments, step S204 includes:

[0123] Step S2041, adjusting the original two-dimensional plane coordinate data according to the alarm level weight to obtain corresponding new two-dimensional plane coordinate data.

[0124] In some embodiments, the original two-dimensional plane coordinate data includes: first-dimensional coordinate data x org and the second dimension coordinate data y org ;

[0125] The new two-dimensional plane coordinate data includes: the first dimension coordinate data x new and the second dimension coordinate data y new ;

[0126] x new =x org +AlarmWeight

[0127] y new =y org +AlarmWeight

[0128] Among them, AlarmWeight represents the weight of the alarm level.

[0129] Of course, the above-mentioned situation of directly adding each dimension of the original two-dimensional plane coordinate data to the weight of the alarm level to obtain the new two-dimensional plane coordinate data is only an optional implementation scheme in the present disclosure, which will not limit the technical scheme of the present disclosure. For example, in the present disclosure, each dimension of the original two-dimensional plane coordinate data can also be subtracted from the weight of the alarm level, or other algorithms can be designed based on the weight of the alarm level.

[0130] Step S2042: Display the new two-dimensional plane coordinate data at the position represented by the two-dimensional map using a display scheme.

[0131] In the disclosed embodiment, the alarm level weight is represented by a decimal number, which can be directly calculated with the coordinate data in the original two-dimensional plane coordinate data.

[0132] In the present disclosure, the alarm level weights are reused, and the alarm level weights of the front-end sensing devices are pre-designed, that is, different front-end sensing devices corresponding to the same original two-dimensional plane coordinate data are configured with different alarm level weights, and the original two-dimensional plane coordinate data are adjusted by the alarm level weights of each front-end sensing device to obtain corresponding new two-dimensional plane coordinate data, so that the warning information of different front-end sensing devices corresponding to the same original two-dimensional plane coordinate data forms scattered points when displayed in the two-dimensional plane, thereby avoiding the problem of stacking during the display of the warning information.

[0133] It should be noted that in the present disclosure, the alarm level weight will be reused to adjust the original two-dimensional plane coordinate data. In order to avoid the new two-dimensional plane coordinate data being too far away from the original two-dimensional plane coordinate data, resulting in low position accuracy, the value of the alarm level weight does not need to be designed to be too large.
