[0031] Embodiment 1

[0032] Figure 1 This is a flow chart of a method for generating an alarm trajectory provided in Embodiment 1 of the present invention. The embodiment of the present invention is applicable to the case of generating an alarm trajectory, and the method can be executed by an alarm trajectory generating device, and the alarm trajectory generating device can be implemented in the form of hardware and / or software.

[0033] See also Figure 1 The alarm trajectory generation method shown includes:

[0034] S101. Obtain at least one personnel coordinate determined based on a communication positioning device carried by a nuclear power plant personnel.

[0035] The nuclear power plant personnel may be personnel within the nuclear power plant location area. The communication positioning device may be a device for positioning and tracking the nuclear power plant personnel. The personnel coordinates may be the location coordinates of the nuclear power plant personnel within the nuclear power plant.

[0036] Specifically, the nuclear power plant personnel and the communication positioning equipment correspond one to one. The communication positioning equipment is carried by the nuclear power plant personnel. The personnel coordinate collection frequency and coordinate collection time can be preset. For example, the coordinate collection time can be the time when the nuclear power plant personnel obtain the communication positioning equipment. Starting from the coordinate collection time, the communication positioning equipment starts to collect the coordinates of the moving position of the nuclear power plant personnel according to the preset personnel coordinate collection frequency, and obtains at least one personnel coordinate. At the same time, each time a personnel coordinate is collected, the time when the personnel coordinate is collected is recorded at the same time. The personnel coordinates correspond to the time when the personnel coordinates are collected. Each personnel coordinate and the collection time corresponding to each personnel coordinate are stored in the database corresponding to the nuclear power plant personnel identification.

[0037] S102: When it is detected according to the coordinates of each person that a nuclear power plant personnel enters an unauthorized alarm area, at least one acquisition coordinate is obtained by screening according to the coordinates of each person.

[0038] The collected coordinates may be the coordinates of the personnel obtained after screening the coordinates of each personnel.

[0039] Specifically, some environments in nuclear power plants are not friendly to the health of nuclear power plant personnel, and are usually divided into supervision areas, control areas, and non-control areas according to radiation doses. The radiation doses in different areas are different. Among them, the supervision area requires personnel to conduct regular radiation dose assessments; the control area usually requires personnel to wear protective equipment and follow specific processing procedures before entering; although the radiation dose in the non-control area is low, personnel still need to abide by the corresponding safety rules. There are various types of people entering nuclear power plants, which can be patrol personnel or temporary visitors. Different people can enter different areas. For example, temporary visitors cannot enter the supervision area. When it is detected that the nuclear power plant personnel enter the alarm area where they are not authorized to enter according to the coordinates of each person, it is necessary to obtain the walking trajectory of the nuclear power plant personnel and control the walking route of the nuclear power plant personnel, but it is not necessary to generate walking trajectories for all the personnel coordinates corresponding to the nuclear power plant personnel. The screening conditions can be preset according to the needs, and the coordinates of each person of the personnel can be screened to obtain the collection coordinates.

[0040] S103: De-duplicate the collected coordinates to obtain at least one warning coordinate.

[0041] The deduplication process may be an operation of deleting the same or similar coordinates in each collected coordinate. The warning coordinates may be the collected coordinates of the nuclear power plant personnel used to generate the trajectory.

[0042] Specifically, when nuclear power plant personnel walk in the nuclear power plant, they may move back and forth in a small area, or stay still in a small area for a long time, then the communication positioning device will collect at least one acquisition coordinate with a close distance. Only one acquisition coordinate with a close distance in the area can be selected for retention, and the rest of the acquisition coordinates can be deleted to reduce duplicate coordinates, so that the generated alarm trajectory is more accurate.

[0043] S104: Generate an alarm trajectory according to each alarm coordinate.

[0044] Among them, the alarm trajectory can be the walking route of the nuclear power plant personnel generated according to the alarm coordinates.

[0045] Specifically, the three-dimensional map data of the nuclear power plant is obtained, and at least one map coordinate is generated in the three-dimensional map data of the nuclear power plant according to each alarm coordinate. According to the collection time corresponding to each alarm coordinate, a connection line between each map coordinate is established in chronological order to generate an alarm trajectory corresponding to the nuclear power plant personnel.

[0046] The technical solution of the embodiment of the present invention obtains at least one personnel coordinate determined based on the communication positioning equipment carried by the nuclear power plant personnel; when it is detected according to the coordinates of each personnel that the nuclear power plant personnel enter the alarm area where they are not authorized to enter, at least one collection coordinate is obtained by screening according to the coordinates of each personnel; each collection coordinate is deduplicated to obtain at least one alarm coordinate; an alarm trajectory is generated according to each alarm coordinate, and the personnel coordinates are screened through multi-dimensional data, thereby reducing the amount of data to be processed, improving the efficiency of obtaining the personnel coordinates, performing different operations on different coordinates, and improving the accuracy of alarm trajectory generation.

[0047] Embodiment 2

[0048] Figure 2 This is a flow chart of a method for generating an alarm trajectory provided by Embodiment 2 of the present invention. Based on the above embodiments, this embodiment of the present invention optimizes and improves the alarm trajectory generation operation.

[0049] Further, "detecting that nuclear power plant personnel have entered an alarm area where they have no permission to enter based on the coordinates of each personnel" is refined into "obtaining at least one nuclear power plant alarm area and the regional alarm level corresponding to each nuclear power plant alarm area; obtaining the current personnel coordinates and personnel authority level corresponding to the nuclear power plant personnel; comparing the current personnel coordinates corresponding to the nuclear power plant personnel with each nuclear power plant alarm area to obtain an area comparison result; comparing the personnel authority level corresponding to the nuclear power plant personnel with the regional alarm level corresponding to each nuclear power plant alarm area to obtain a level comparison result; determining the alarm area where the nuclear power plant personnel have no permission to enter based on the area comparison result and the level comparison result" to improve the operation of generating the alarm trajectory.

[0050] It should be noted that for the parts not described in detail in the embodiments of the present invention, reference may be made to the descriptions of other embodiments.

[0051] See also Figure 2 The alarm trajectory generation method shown includes:

[0052] S201. Obtain at least one personnel coordinate determined based on a communication positioning device carried by a nuclear power plant personnel.

[0053] S202: Obtain at least one nuclear power plant alarm area and the regional alarm level corresponding to each nuclear power plant alarm area.

[0054] The nuclear power plant alarm area may be a dangerous monitoring area within the nuclear power plant, and an alarm will be issued if there are nuclear power plant personnel who have no authority to enter the area. The regional alarm level may be used to describe the authority level for entering the nuclear power plant alarm area.

[0055] Specifically, the nuclear power plant includes at least one supervision area, at least one control area and at least one non-control area. Each area can be divided by an electronic fence. One nuclear power plant alarm area corresponds to one regional alarm level. The regional alarm level of the nuclear power plant alarm area is determined by the radiation dose in the nuclear power plant alarm area. If the radiation dose in the nuclear power plant alarm area is more, the regional alarm level of the nuclear power plant alarm area is higher; if the radiation dose in the nuclear power plant alarm area is less, the regional alarm level of the nuclear power plant alarm area is lower. Electronic fences with different regional alarm levels can be set for different nuclear power plant alarm areas. Once the coordinates of unauthorized nuclear power plant personnel are in the area surrounded by the electronic fence, an alarm will be triggered and an alarm trajectory of the nuclear power plant personnel will be generated, thereby improving the traceability of nuclear power plant personnel control. Alarm methods include but are not limited to: pop-up alarms, SMS alarms, sound alarms or flash alarms.

[0056] S203, obtaining the current personnel coordinates and personnel authority levels corresponding to the nuclear power plant personnel.

[0057] The current personnel coordinates may be the personnel coordinates of the nuclear power plant personnel collected by the communication positioning device at the current moment. The personnel authority level may be the authority level of the nuclear power plant personnel to enter the nuclear power plant alarm area.

[0058] Specifically, different nuclear power plant personnel correspond to different personnel types, and different personnel types correspond to different personnel authority levels. If the personnel type is a tourist type, the personnel authority level is low, and if the personnel type is an inspection personnel, the personnel authority level is high. The correspondence between different personnel types and personnel authority levels can be preset, and according to the personnel type of the nuclear power plant personnel, the personnel authority level corresponding to the nuclear power plant personnel can be searched according to the personnel type. The search method includes, but is not limited to: sequential search algorithm, block search algorithm, tree table search algorithm or hash search algorithm, etc., and the embodiment of the present invention does not limit this.

[0059] S204, comparing the current personnel coordinates corresponding to the nuclear power plant personnel with the alarm areas of each nuclear power plant to obtain an area comparison result.

[0060] The area comparison result may be a result of comparing the current personnel coordinates corresponding to the nuclear power plant personnel and the alarm areas of each nuclear power plant.

[0061] Specifically, the coordinate data of the contour of each nuclear power plant alarm area is obtained. When a nuclear power plant personnel enters an area without permission, an alarm will be triggered. The communication positioning device collects the personnel coordinates of the nuclear power plant personnel in real time and obtains the personnel coordinates of the nuclear power plant personnel at the current moment. The current personnel coordinates are compared with the coordinate data of the contour of each nuclear power plant alarm area to obtain the area comparison result, which can determine whether the nuclear power plant personnel have entered the nuclear power plant alarm area.

[0062] S205. Compare the personnel authority levels corresponding to the nuclear power plant personnel and the regional alarm levels corresponding to the alarm areas of each nuclear power plant to obtain a level comparison result.

[0063] Specifically, when the personnel authority level of the nuclear power plant personnel is greater than or equal to the regional alarm level corresponding to the nuclear power plant alarm area, it indicates that the nuclear power plant personnel have the authority to enter the nuclear power plant alarm area; when the personnel authority level of the nuclear power plant personnel is less than the regional alarm level corresponding to the nuclear power plant alarm area, it indicates that the nuclear power plant personnel do not have the authority to enter the nuclear power plant alarm area. Therefore, according to the personnel authority level corresponding to the nuclear power plant personnel and the regional alarm level corresponding to each nuclear power plant alarm area, the level comparison result is obtained to determine whether the nuclear power plant personnel have the authority to enter the nuclear power plant alarm area.

[0064] S206. When determining the alarm area that the nuclear power plant personnel have no right to enter according to the area comparison results and the level comparison results, at least one acquisition coordinate is obtained by screening the coordinates of each person.

[0065] Specifically, if the area comparison result is that the nuclear power plant thermal personnel enter the nuclear power plant alarm area, and the level comparison result is that the nuclear power plant personnel have the authority to enter the nuclear power plant alarm area, then no alarm is issued and no alarm trajectory is generated; if the area comparison result is that the nuclear power plant thermal personnel enter the nuclear power plant alarm area, and the level comparison result is that the nuclear power plant personnel do not have the authority to enter the nuclear power plant alarm area, then an alarm is required and an alarm trajectory needs to be generated. If the alarm trajectory of the nuclear power plant personnel needs to be generated, at least one collection coordinate is obtained according to the coordinates of each person of the nuclear power plant personnel.

[0066] S207: De-duplicate the collected coordinates to obtain at least one warning coordinate.

[0067] S208: Generate an alarm trajectory according to each alarm coordinate.

[0068] The embodiment of the present invention obtains at least one nuclear power plant alarm area and the regional alarm level corresponding to each nuclear power plant alarm area; obtains the current personnel coordinates and personnel authority level corresponding to the nuclear power plant personnel; compares the current personnel coordinates corresponding to the nuclear power plant personnel with each nuclear power plant alarm area to obtain a regional comparison result; compares the personnel authority level corresponding to the nuclear power plant personnel with the regional alarm level corresponding to each nuclear power plant alarm area to obtain a level comparison result; and determines the alarm area that the nuclear power plant personnel have no authority to enter based on the regional comparison result and the level comparison result.

[0069] Optionally, at least one acquisition coordinate is obtained based on the coordinate screening of each personnel, including: obtaining the current acquisition time and coordinate screening time corresponding to the current personnel coordinates of the nuclear power plant personnel; calculating the screening time range based on the current acquisition time and coordinate screening time; obtaining the acquisition time corresponding to each personnel coordinate; comparing the acquisition time corresponding to each personnel coordinate with the screening time range, and determining at least one acquisition coordinate.

[0070] The current acquisition time may be the time when the communication positioning device acquires the coordinates of the current personnel. The coordinate screening time may be a preset time length for screening the coordinates of each personnel of the nuclear power plant personnel. The screening time range may be a time range for screening the coordinates of each personnel of the nuclear power plant personnel.

[0071] Specifically, the current acquisition time and coordinate screening time corresponding to the current personnel coordinates of the nuclear power plant personnel are obtained, and the coordinate screening time is subtracted from the current acquisition time to obtain the starting time of the calculated time range. The end time of the time range is determined according to the current acquisition time. The screening time range is determined according to the starting time and the end time. The acquisition time corresponding to each personnel coordinate corresponding to the nuclear power plant personnel is obtained. The acquisition time corresponding to each personnel coordinate is compared with the screening time range respectively to determine at least one acquisition coordinate.

[0072] By obtaining the current collection time and coordinate screening time corresponding to the current personnel coordinates of the nuclear power plant personnel; calculating the screening time range according to the current collection time and coordinate screening time; obtaining the collection time corresponding to each personnel coordinate; comparing the collection time corresponding to each personnel coordinate with the screening time range, determining at least one collection coordinate, and reducing the data volume of personnel coordinates through multi-dimensional data screening, the accuracy of alarm trajectory generation is improved.

[0073] Optionally, each acquisition coordinate is deduplicated to obtain at least one alarm coordinate, including: obtaining a preset deduplication distance; sorting each acquisition coordinate according to the acquisition time corresponding to each acquisition coordinate to obtain an acquisition coordinate sequence; screening the target acquisition coordinates in the acquisition coordinate sequence; calculating the micro-movement area according to the preset deduplication distance and the target acquisition coordinates; deleting the acquisition coordinates in the micro-movement area except the target acquisition coordinates in the acquisition sequence; reselecting the target acquisition coordinates in the acquisition coordinate sequence, deduplicating the acquisition coordinate sequence, until all the acquisition coordinates in the acquisition coordinate sequence are traversed to obtain at least one alarm coordinate.

[0074] The preset value of the deduplication distance is used to calculate the movement range of the nuclear power plant personnel. The acquisition coordinate sequence can be a sequence of acquisition coordinates generated in the order of acquisition time. The target acquisition coordinates can be acquisition coordinates prepared for deduplication processing. The micro-movement area can be a small range of movement area corresponding to the target acquisition coordinates.

[0075] Specifically, during the movement, the personnel of the nuclear power plant may stay in a small area for a long time, or move within a smiling range. Then, the communication positioning device will collect at least one coordinate with a small distance. If the left and right coordinates of the area are used to generate the alarm trajectory, the amount of coordinate data processed is large, and the route is not clear enough. Therefore, the preset deduplication distance is obtained, and each acquisition coordinate is sorted according to the acquisition time corresponding to each acquisition coordinate to obtain an acquisition coordinate sequence. The target acquisition coordinate is screened in the acquisition coordinate sequence. The target acquisition coordinate is selected in sequence according to the order of each acquisition coordinate in the acquisition coordinate sequence. If the acquisition coordinate is deleted during deduplication, the next acquisition coordinate is selected as the target acquisition coordinate according to the order of the acquisition coordinate sequence. According to the preset deduplication distance as the radius and the target acquisition coordinate as the center of the circle, a circular area is calculated as the micro-movement area. The acquisition coordinates remaining in the micro-movement area except the target acquisition coordinate in the acquisition sequence are deleted. The target acquisition coordinate is reselected in the acquisition coordinate sequence, and the acquisition coordinate sequence is deduplicated until all the acquisition coordinates in the acquisition coordinate sequence are traversed to obtain at least one alarm coordinate.

[0076] By obtaining a preset deduplication distance; sorting each acquisition coordinate according to the acquisition time corresponding to each acquisition coordinate to obtain an acquisition coordinate sequence; screening the target acquisition coordinates in the acquisition coordinate sequence; calculating the micro-movement area according to the preset deduplication distance and the target acquisition coordinates; deleting the acquisition coordinates in the micro-movement area except the target acquisition coordinates in the acquisition sequence; reselecting the target acquisition coordinates in the acquisition coordinate sequence, deduplicating the acquisition coordinate sequence, until all the acquisition coordinates in the acquisition coordinate sequence are traversed to obtain at least one alarm coordinate, and screening similar acquisition coordinates to improve the accuracy of alarm trajectory generation.

[0077] Optionally, at least one personnel coordinate determined based on a communication positioning device carried by nuclear power plant personnel is obtained, including: obtaining at least one positioning base station and the base station position corresponding to each positioning base station; obtaining the sending signal time of the communication positioning device and the receiving signal time of each positioning base station; and calculating at least one user coordinate corresponding to the nuclear power plant personnel based on each receiving signal time, sending signal time and each base station position.

[0078] The positioning base station may be a device for locating the position coordinates of a person. The base station position may be the position coordinates where the positioning base station is installed. The signal sending time may be the time when the communication positioning device sends the signal. The signal receiving time may be the time when the positioning base station receives the signal sent by the communication positioning device.

[0079] Specifically, at least one positioning base station and the base station position corresponding to each positioning base station are obtained, the sending signal time of the communication positioning device and the receiving signal time of each positioning base station are obtained, and the ultra-wideband technology (Ultra Wide Band, UWB) technology is used to determine the position of the communication positioning device based on the time difference (Time Difference of Arrival, TDOA) between the signal arrival at different receiving points according to the receiving signal time, the sending signal time and the position of each base station, and calculate at least one user coordinate corresponding to the nuclear power plant personnel.

[0080] By obtaining at least one positioning base station and the base station positions corresponding to each positioning base station; obtaining the sending signal time of the communication positioning equipment and the receiving signal time of each positioning base station; and calculating at least one user coordinate corresponding to the nuclear power plant personnel according to each receiving signal time, sending signal time and each base station position, positioning information can be obtained in dense multipath places such as indoors, with high positioning accuracy, and it is not affected by the electromagnetic radiation inside the nuclear power plant, which improves the accuracy of alarm trajectory generation.

[0081] Optionally, before obtaining at least one personnel coordinate determined based on the communication positioning device carried by the nuclear power plant personnel, it also includes: collecting image features of the nuclear power plant personnel when the nuclear power plant personnel enter the nuclear power plant; providing corresponding authority cards to the nuclear power plant personnel based on the image features of the nuclear power plant personnel, and serving as a communication positioning device, the communication positioning device sends signals to the outside, and the positioning base station receives the signals sent by the communication positioning device.

[0082] The image feature may be feature information of the nuclear power plant personnel identified from the collected image of the nuclear power plant personnel. The authority card may be a card with a positioning tag installed.

[0083] Specifically, a permission library is obtained in advance, and the permission library stores at least one identification of a nuclear power plant personnel, facial feature information corresponding to each identification, and personnel authority level corresponding to each identification. When the nuclear power plant personnel enter the nuclear power plant, the image features of the nuclear power plant personnel are collected, and the personnel authority level of the nuclear power plant personnel is obtained based on the image features of the nuclear power plant personnel. The permission card corresponding to the nuclear power plant personnel is queried based on the personnel authority level, and the corresponding permission card is provided to the nuclear power plant personnel, and the communication positioning device is used as a communication positioning device for the nuclear power plant personnel. The communication positioning device sends a signal to the outside, and the positioning base station receives the signal sent by the communication positioning device.

[0084] By collecting image features of nuclear power plant personnel when they enter the nuclear power plant, providing corresponding authority cards to the nuclear power plant personnel based on their image features, and using the cards as communication and positioning devices, the communication and positioning devices send signals outward, and the positioning base station receives the signals sent by the communication and positioning devices. Different operations are performed for different nuclear power plant personnel, which refines the operations for generating alarm trajectories and improves the accuracy of generating alarm trajectories.

[0085] Optionally, at least one nuclear power plant alarm area and the regional alarm level corresponding to each nuclear power plant alarm area are obtained, including: obtaining at least one nuclear power plant equipment type and the equipment alarm level corresponding to each nuclear power plant equipment type; obtaining the safety radius corresponding to the equipment alarm level according to the equipment alarm level query; for each nuclear power plant equipment type, determining the alarm area corresponding to the nuclear power plant equipment type according to the nuclear power plant equipment type, the equipment alarm level corresponding to each nuclear power plant equipment type and the safety radius corresponding to the equipment alarm level.

[0086] Among them, the nuclear power plant equipment type can be the type of nuclear power plant equipment in the nuclear power plant. For example, the nuclear power plant equipment type can be nuclear island equipment, conventional island equipment and BOP (Balance of Plant) equipment. The equipment alarm level can be the alarm level corresponding to the nuclear power plant equipment type. The higher the equipment alarm level, the greater the radiation dose of the nuclear power plant equipment. The safety radius can be the radius of the alarm area corresponding to the preset equipment alarm level, which can be used to calculate the alarm area to ensure that the radiation dose of nuclear power plant personnel outside the alarm area does not affect the safety of nuclear power plant personnel.

[0087] Specifically, the pre-safety radius of nuclear power plant equipment types corresponds one to one. Obtain at least one nuclear power plant equipment type and the equipment alarm level corresponding to each nuclear power plant equipment type, and the acquisition method can be preset through industry experience. According to the equipment alarm level query, the safety radius corresponding to the equipment alarm level is obtained. The higher the equipment alarm level, the larger the safety radius, and the smaller the equipment alarm level, the smaller the value of the safety radius. Obtain the location coordinates of the nuclear power plant equipment, take the location coordinates of the nuclear power plant equipment as the center of the circle, and the safety radius as the radius, and calculate the alarm area corresponding to the nuclear power plant equipment type.

[0088] By obtaining at least one nuclear power plant equipment type and the equipment alarm level corresponding to each nuclear power plant equipment type; obtaining the safety radius corresponding to the equipment alarm level according to the equipment alarm level query; for each nuclear power plant equipment type, according to the nuclear power plant equipment type, the equipment alarm level corresponding to each nuclear power plant equipment type and the safety radius corresponding to the equipment alarm level, determining the alarm area corresponding to the nuclear power plant equipment type, dividing different areas for different types of nuclear power plant equipment, ensuring maximum land utilization and protecting personal safety.
