[0036] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] The present application embodiment discloses a schematic diagram of a positioning system for port equipment. Figure 1 The positioning system includes port equipment 1, differential base station 2, positioning server 3 and positioning satellite 4.

[0038] A positioning terminal is installed on the port equipment 1. The port equipment 1 includes at least one of a bridge crane, a gantry crane, a rail crane, a forklift, a reach stacker and a container truck. The port equipment 1 obtains its own positioning information through the positioning satellite 4 and sends the positioning information to the positioning server 3.

[0039] The differential base station 2 is a device for improving positioning accuracy. Exemplarily, the differential base station 2 stores its own accurate position. After the differential base station 2 calculates the positioning position through the information sent by the positioning satellite 4, it will calculate the positioning error of the positioning satellite 4 through the difference between the accurate position and the positioning position, and send the positioning error to the port area device 1. The port area device 1 will correct its own positioning information through the positioning error of the differential base station 2.

[0040] The positioning server 3 is used to collect and manage the positioning information of the port equipment 1. Optionally, a positioning platform is running on the positioning server 3, and the positioning platform is a system platform that provides positioning services. Exemplarily, the port equipment 1 will periodically provide its own positioning information to the positioning server 3.

[0041] The positioning satellite 4 is used to send information to the port area equipment 1 and the differential base station 2, so that the port area equipment 1 and the differential base station 2 can obtain their own positioning information.

[0042] The present application embodiment discloses a method for detecting a positioning fault of a port equipment. Figure 1 . Reference Figure 2 , the method comprising: Step S201: Detect the network status of the port area equipment.

[0043] The network status includes offline status and online status. The offline status means that the port equipment has not established a communication connection with the positioning platform, and the online status means that the port equipment has established a communication connection with the positioning platform.

[0044] Exemplarily, the positioning platform sends query information to the port area equipment; if the positioning platform receives information returned by the port area equipment, it means that the port area equipment is online; if the positioning platform does not receive information returned by the port area equipment, it means that the port area equipment is offline.

[0045] Exemplarily, the port area equipment periodically reports its own positioning information to the positioning platform. If the positioning platform can periodically obtain the positioning information reported by the port area equipment, it means that the port area equipment is online; if the positioning platform does not obtain the positioning information reported by the port area equipment, it means that the port area equipment is offline.

[0046] Step S202: If the port area device is in an offline state, the reconnection frequency and moving path of the port area device are obtained according to the log information of the port area device on the positioning platform.

[0047] Log information refers to various records generated by the positioning platform during operation. In this application, the log information includes at least one of the positioning information reported by the port equipment, the reporting time of the positioning information, the task of the port equipment, and the moving path of the port equipment.

[0048] When the port state is in an offline state, the port state will try to re-establish a communication connection with the positioning platform. The reconnection frequency refers to the frequency of establishing a communication connection between the port device and the positioning platform. Exemplarily, the number of communications between the port device and the positioning platform within a preset period of time is obtained through log information; the reconnection frequency is calculated based on the aforementioned number of communications.

[0049] Step S203: Generate the positioning failure cause of the port equipment according to the reconnection frequency and the moving path.

[0050] When the port equipment is offline, the positioning platform cannot obtain the positioning information of the port equipment, so the positioning platform will regard the port equipment as a positioning failure. At this time, it is necessary to promptly determine the cause of the positioning failure of the port equipment.

[0051] Step S204: If the port area equipment is in an online state, it is determined whether the positioning information of the port area equipment is in an available state.

[0052] If the positioning information of the port area equipment is in an available state, executing steps S205 to S206; If the positioning information of the port equipment is not in an available state, step S207 is executed.

[0053] It should be noted that even if the port equipment has established a communication connection with the positioning platform, it cannot be guaranteed that the port equipment will upload positioning information. Therefore, it is necessary to further determine whether the positioning information of the port equipment is in an available state.

[0054] In some embodiments, the port information only reports heartbeat information but does not report positioning information. In this case, it should be considered that the port equipment is not in an available state.

[0055] Step S205: If yes, obtain the positioning status corresponding to the positioning information.

[0056] The positioning state is used to describe the accuracy of the positioning information and the generation method of the positioning information. In this embodiment, the positioning state includes INIT, SINGLE, DGPS, PPS, FIX, FLOAT, ESTIMATED, MANUAL, SIMULATED and UNKWOWN.

[0057] INIT indicates that the port equipment is in the initialization state. The positioning satellite has not locked the port equipment yet, or the positioning terminal on the port equipment has just started.

[0058] SINGLE means that the positioning information of the port equipment is generated based on a single receiver receiving information from a positioning satellite, and the positioning accuracy is low. For example, the accuracy of the positioning information is between several meters and tens of meters.

[0059] DGPS means that the positioning information of the port equipment is corrected using a differential base station, and the positioning accuracy is relatively high. For example, the positioning accuracy is several meters or higher.

[0060] FIX means that the positioning information of the port equipment accurately indicates the actual location of the port equipment, and the positioning accuracy is high.

[0061] FLOAT indicates that the positioning information of the port equipment has been corrected using a differential base station, but its positioning accuracy is within a large range and the positioning accuracy is poor.

[0062] ESTIMATED indicates that the location information of the port equipment is obtained through estimation.

[0063] MANUAL means that the location information of the port equipment is entered manually.

[0064] SIMULATED means that the positioning information of the port equipment is obtained through simulation data, and the positioning accuracy is unreliable.

[0065] UNKWOWN indicates that the location information of the port equipment cannot be obtained.

[0066] Step S206: When the positioning state does not match the preset normal positioning state, a positioning failure cause is generated according to the positioning information and the positioning state.

[0067] Optionally, the preset normal positioning states include the above-mentioned INIT, DGPS and FIX.

[0068] Step S207: If not, generate and locate the cause of the fault according to the log information of the port equipment.

[0069] When the positioning information of the port equipment is unavailable, it is necessary to obtain the cause of the positioning failure through logs.

[0070] In summary, when a port equipment fails, the cause of the failure can be quickly located through the positioning information and log information of the port equipment, and the port equipment can be repaired in time.

[0071] In the following embodiment, a method for generating a positioning fault cause according to positioning information and positioning status is described. Figure 2 . Reference Figure 3 , the method comprising: Step S301: Count the reported location points of other port equipment except the port equipment.

[0072] The reported location point refers to the location point of other port equipment on the map.

[0073] Other port area equipment refers to all or part of the port area equipment in the port area except the current port area equipment.

[0074] Step S302: Determine whether the position deviation between the reported position point and the actual position points of other port equipment is less than a preset deviation.

[0075] If the position deviation between the reported position point and the actual position points of other port equipment is less than the preset deviation, step S303 is executed; If the position deviation between the reported position point and the actual position points of other port equipment is not less than the preset deviation, step S304 to step S306 are executed.

[0076] The preset deviation is a preset empirical value, which is not specifically limited in the present application embodiment.

[0077] In some embodiments, other port area equipment may be fixed equipment, that is, the position of the port area equipment will not change. In this case, the position deviation can be calculated by comparing the reported position point with the actual position point.

[0078] Step S303: If yes, a first positioning fault cause is generated according to the positioning antenna and the positioning terminal of the port equipment, where the first positioning fault cause is used to indicate that the positioning fault of the port equipment is related to the positioning antenna or the positioning terminal.

[0079] If the position deviation between the reported position point and the actual position point of other port equipment is less than the preset deviation, it means that other port equipment has no positioning failure problem, and the positioning failure is unique to the current port equipment. Therefore, the cause of the positioning failure of the port equipment comes from the current port terminal. Therefore, in this case, the first positioning failure cause is related to the positioning-related components on the port equipment, which include positioning antennas or positioning terminals.

[0080] Step S304: If not, then detect the working status of the differential base station.

[0081] Exemplarily, a detection signal is sent to the differential base station. If the differential base station returns a first return signal, it indicates that the differential base station is in a normal working state. If the differential base station returns a second return signal, it indicates that the differential base station is in an abnormal working state.

[0082] Step S305: When the differential base station is in a normal working state, a second positioning fault cause is generated according to the differential configuration of the port equipment, and the second positioning fault cause is used to indicate that the positioning fault of the port equipment is related to the differential configuration.

[0083] The differential configuration refers to the configuration parameters used for differential positioning on the port equipment.

[0084] When the differential base station is in normal working state, the cause of the positioning failure of the port area equipment comes from the current port area equipment. Therefore, in this case, the first positioning failure cause is related to the differential configuration of the port area equipment.

[0085] Step S306: When the differential base station is in an abnormal working state, a third positioning fault cause is generated according to the abnormal working state, and the third positioning fault cause is used to indicate that the positioning fault of the port equipment is related to the differential base station.

[0086] When the differential base station is in an abnormal working state and other port equipment also has positioning failures, the positioning failure of the port equipment is caused by the differential base station.

[0087] In summary, the cause of the failure of the port area equipment can be quickly found out, and the cause of the failure is related to the positioning antenna or the positioning terminal, or to the differential configuration, or to the differential base station.

[0088] In the following embodiment, if it is determined that the differential base station has a fault, the differential parameters of the differential base station can be updated. Therefore, the embodiment of the present application discloses a flow chart of a method for updating a differential base station. Figure 4 , the method comprising: Step S401: Count the offset directions of the position offsets corresponding to other port area equipment.

[0089] The offset direction is the direction from the actual position point to the reported position point.

[0090] Step S402: performing clustering operation on the offset directions to obtain offset direction clustering results.

[0091] In some other embodiments, the same offset directions are grouped into the same group of offset direction clustering results to obtain the offset direction clustering results.

[0092] In some other embodiments, if the first offset direction and the second offset direction are both located within the same preset angle interval, it is considered that the first offset direction and the second offset direction are the same within an error.

[0093] Step S403: obtaining the target offset direction clustering result having the most port equipment in the offset direction clustering result, and the total number of directions corresponding to the target offset direction clustering result.

[0094] Exemplarily, the offset direction clustering results are sorted according to the number of port equipment, so as to be arranged from large to small, and the target offset direction clustering results are obtained.

[0095] Step S404: when the total number of directions is greater than a preset number, the differential parameters of the differential base station are corrected according to the target offset direction and the target offset distance corresponding to the target offset direction clustering result.

[0096] The preset number is a preset empirical value, and the embodiment of the present application does not specifically limit the preset number.

[0097] The differential parameter is used to indicate the deviation between the actual position of the port equipment and the satellite positioning information.

[0098] Exemplarily, the positioning information of the port equipment is generated by the differential parameters provided by the positioning base station and the satellite positioning information received by the port equipment itself. For example, assuming that the satellite positioning information is longitude and latitude, and the differential parameters include the deviation distance and the deviation direction, then the point represented by the longitude and latitude is taken as the origin, and the length of the deviation distance is calculated in the deviation direction to obtain the actual position of the port equipment, which is the positioning information of the port equipment.

[0099] Furthermore, a first directed line segment is generated according to the deviation distance and deviation angle of the differential parameter, so that the first directed line segment points from the position corresponding to the satellite positioning information to the actual position. A second directed line segment is generated according to the target offset distance and target offset direction, so that the second directed line segment points from the current positioning information of the port area equipment to the actual position. The vector sum of the first directed line segment and the second directed line segment is calculated, and the differential parameters of the differential base station are corrected.

[0100] In summary, when a differential base station fails and causes a large number of port equipment to drift in the same direction, the differential base station can be corrected to make the positioning information of each port equipment normal.

[0101] In the following embodiments, when large-scale collective drift occurs in the port equipment, the fault may also be caused by the presence of an obstruction in the antenna receiving direction of the differential base station receiving antenna, thereby affecting the accuracy of the differential parameters of the differential base station. The present application embodiment discloses a flow chart of a method for updating the antenna receiving direction. Figure 5 , the method comprising: Step S501: Execute a first updating step, which includes updating the antenna receiving direction of the differential base station.

[0102] Optionally, the antenna receiving direction of the differential base station is rotated toward a preset direction by a preset angle.

[0103] Step S502: Execute the second updating step, which includes updating the location information of the port equipment.

[0104] After the antenna receiving direction rotates through a preset angle, the location information of the port equipment is updated according to the differential parameters of the differential base station.

[0105] Step S503: Repeat the first updating step and the second updating step until the rotation angle of the antenna receiving direction is greater than a preset angle.

[0106] The preset angle is a preset empirical value, for example, the preset angle is 360 degrees.

[0107] Exemplarily, after the antenna receiving direction of the differential base station is rotated toward a preset direction by a preset angle, the position information before the update and the position information after the update are compared. If the position information before the update is better than the finer position information after the update, the antenna receiving direction is controlled to continue to rotate toward the preset direction; if the position information before the update is worse than the position information after the update, the antenna receiving direction is controlled to rotate in the opposite direction of the preset direction.

[0108] Step S504: during the rotation of the antenna receiving direction, searching for optimal position information in the position information, and determining the optimal antenna receiving direction corresponding to the optimal position information.

[0109] The optimal position information is the position information that is closest to the actual position during the rotation of the antenna receiving direction.

[0110] In some other embodiments, during the mth rotation of the antenna receiving direction, the mth position information is updated to the m+1th position information, and it is detected that the mth position information is inferior to the m+1th position information, and during the m+1th rotation of the antenna receiving direction, the m+1th position information is updated to the m+2th position information, and it is detected that the mth position information is better than the m+1th position information. Then the mth position information is used as the optimal position information.

[0111] Step S505: Update the antenna receiving direction to the optimal antenna receiving direction.

[0112] Using the optimal antenna receiving direction as the antenna receiving direction of the differential base station can ensure that the differential parameters of the differential base station are as accurate as possible, so that the error of the positioning information of the port equipment is small.

[0113] In summary, the antenna receiving direction of the differential base station is adjusted so that the adjusted optimal antenna receiving direction can obtain positioning information as much as possible.

[0114] The present application also discloses a method for detecting a fault in a port area. Figure 3 . Reference Figure 6 , the method comprising: Step S601: Compare the reconnection frequency with the preset frequency.

[0115] The preset frequency is a preset empirical value, and the embodiment of the present application does not specifically limit the preset frequency.

[0116] When the reconnection frequency is less than the preset frequency, executing steps S602 to S604; When the reconnection frequency is greater than the preset frequency, step S605 to step S606 are executed.

[0117] It should be noted that when the port equipment loses communication connection with the positioning platform, the port equipment will try to re-establish communication connection with the positioning platform. Therefore, the log information on the positioning platform will record the number of times the port equipment reconnects within a certain period of time and calculate the reconnection frequency within the period of time.

[0118] Step S602: when the reconnection frequency is less than the preset frequency, the road surface smoothness of the moving path is obtained.

[0119] When the reconnection frequency is lower than the preset frequency, it means that the disconnection between the port equipment and the positioning platform is not a common situation, but an occasional situation. At this time, the cause of the positioning failure is most likely caused by external factors rather than the port equipment itself.

[0120] Exemplarily, a camera is installed in the port area, and a road surface image of the moving path is captured by the camera, and the road surface flatness is obtained through the road surface image.

[0121] Step S603: If the road surface flatness is greater than the preset flatness, a fourth positioning fault cause is generated, and the fourth positioning fault cause is used to indicate that the positioning fault of the port equipment is related to the road surface flatness.

[0122] When the road surface flatness is greater than the preset flatness, the disconnected area of ​​the port equipment is obtained. The disconnected area refers to the location of the port equipment when the port equipment is disconnected from the positioning platform. The problem area on the moving path where the road surface flatness is greater than the preset flatness is obtained. If the disconnected area is consistent with the problem area, the fourth positioning fault cause is generated. At this time, it means that the port equipment is disconnected from the positioning platform because the bumpy road surface affects the normal operation of the positioning terminal on the port equipment.

[0123] Step S604: If the road surface flatness is less than the preset flatness, obtain the buildings on the moving path. In the case where the building blocks the port equipment, generate a fifth positioning fault cause, which is used to indicate that the positioning fault of the port equipment is related to the building.

[0124] When the road surface flatness is less than the preset flatness, obtain the disconnected area of ​​the port equipment. Obtain the inspection area where the building height on the moving path is greater than the preset height. If the disconnected area is consistent with the inspection area, generate the fifth positioning fault cause. At this time, it means that the port equipment and the positioning platform are disconnected from the communication connection because the obstruction of the building affects the normal operation of the positioning terminal on the port equipment.

[0125] Step S605: When the reconnection frequency is greater than the preset frequency, the connection port of the port area equipment is detected.

[0126] When the reconnection frequency is greater than the preset frequency, it means that the port equipment is disconnected from the positioning platform, which is a common situation. In this case, the cause of the positioning failure is most likely due to the port equipment itself, rather than external factors.

[0127] Step S606: when the connection port does not belong to the preset port, a sixth positioning fault cause is generated, and the sixth positioning fault cause is used to indicate that the positioning fault of the port area equipment is related to the connection port.

[0128] The connection port is the port on the port equipment to which the antenna is connected.

[0129] Exemplarily, the port terminal is provided with an antenna port and a radio port, and the signal line of the positioning antenna can be connected to the two ports and the antenna can work normally. However, when the positioning antenna is connected to the radio port, the data transmission efficiency of the positioning antenna is low, and error codes and bit errors may occur, resulting in positioning information errors. Therefore, when it is detected that the positioning antenna is not connected to the antenna port, a sixth positioning fault is generated.

[0130] In summary, the cause of the failure of the port area equipment can be quickly identified, and the cause of the failure is related to the flatness of the road surface, or to the building, or to the connection port.

[0131] In the following embodiment, if the positioning failure of the port terminal is caused by the obstruction of the building, the movement route of the port equipment in the obstruction area of ​​the building can be predicted to supplement the log information on the positioning platform, which is beneficial for the relevant personnel to maintain the positioning platform and organize the positioning information. Therefore, the embodiment of the present application discloses a flow chart of a method for updating positioning information. Figure 7 , the method comprising: Step S701: Determine the signal blocking area formed by the building according to the shape and position of the building.

[0132] Exemplarily, the projection shape of the building on the ground is determined according to the shape of the building, and the signal blocking area is obtained according to the position and projection shape of the building.

[0133] Step S702: When the port equipment enters the signal blocking area, the predicted positioning information of the port equipment in the signal blocking area is generated according to the moving speed and mission objectives of the port equipment, and the entry time is recorded.

[0134] The predicted positioning information includes the location of the port area information and the correspondence between the location and time.

[0135] Exemplarily, according to the mission objectives of the port equipment, the destination of the port equipment is determined. The entry point of the port equipment into the signal blocking area is obtained. According to the entry point and the destination, the moving path of the port equipment in the signal blocking area is predicted. The moving speed and the moving path are used to generate the predicted positioning information.

[0136] Step S703: When it is detected that the port equipment leaves the signal blocking area, the leaving time is recorded.

[0137] Exemplarily, cameras in the port area are used to determine whether the port equipment leaves the signal blocking area, and the departure time is recorded.

[0138] Exemplarily, when it is detected that the port area equipment establishes a communication connection with the positioning platform, it is determined that the port area equipment leaves the signal blocking area, and the departure time is recorded.

[0139] Step S704: Correct the predicted positioning information according to the entry time and the exit time.

[0140] Exemplarily, the duration of the port equipment's passage in the signal blocking area is obtained based on the difference between the entry time and the exit time; the moving path in the predicted positioning information is extracted. The actual moving speed of the port equipment in the signal blocking area is obtained based on the moving path and the communication duration. The predicted positioning information is corrected based on the actual moving speed and the moving path.

[0141] Step S705: Fill the predicted positioning information into the log information.

[0142] In summary, after the port area equipment enters the signal blocking area, the predicted positioning information can be generated and written into the log information to ensure that the positioning information of the port area equipment can be obtained at any time.

[0143] In the following embodiments, after the port equipment passes through the bumpy area, the port on the positioning terminal may become loose, thereby affecting the subsequent reporting of positioning information. Therefore, the present application embodiment discloses a flow chart of a positioning prompt method. Figure 8 , the method comprising: Step S801: Filter target moving paths whose road surface flatness is greater than a preset flatness.

[0144] The preset flatness is a preset empirical value.

[0145] Exemplarily, a road surface image of the moving path is acquired through a camera, and the road surface flatness is identified through the road surface image.

[0146] Step S802: After the port area device passes through the target moving path, a detection signal is sent to the port area device, and the detection signal passes through the connection port of the port area device.

[0147] After the port equipment passes through the target moving path, due to the poor flatness of the road surface of the target moving path, the port equipment will be bumpy, which may cause the port on the positioning terminal to loosen, thereby causing positioning failure. Therefore, it is necessary to detect the port to determine whether it is loose.

[0148] Exemplarily, the port area equipment needs to receive the detection signal through the antenna, and the detection signal needs to pass through the connection port to be read by the port area equipment. At this time, the port area equipment can record the signal strength of the detection signal transmitted to the port area equipment.

[0149] Step S803: Detect the signal strength of the detection signal.

[0150] Exemplarily, the signal strength of the detection signal of the port equipment is detected.

[0151] Step S804: When the signal strength is less than the preset strength, a prompt signal is sent to the port area equipment.

[0152] The preset strength is a preset empirical value, and the embodiment of the present application does not limit the specific value of the preset strength.

[0153] Optionally, the port area equipment generates a prompt voice after the prompt signal, and the prompt voice is used to prompt the operator of the port area equipment.

[0154] In some embodiments, when the signal strength is less than a preset strength, the port area device generates an alarm signal. The port area device sends the alarm signal to the positioning platform. After acquiring the alarm signal, the port area device sends a prompt signal to the port area device.

[0155] In summary, after the port equipment passes through the target moving path, it will determine whether it is necessary to send a prompt signal based on the signal strength of the return signal. The prompt signal can prompt relevant personnel to adjust the port equipment.
