[0025] Example 1

[0026] Figure 1 This is a flow chart of a dual positioning inspection method provided by the first embodiment of the present invention. This embodiment can be applied to a dual positioning inspection device for execution. The device can be implemented by software and / or hardware and can generally be integrated into a dual positioning inspection system. The dual positioning inspection system of this embodiment includes an inspection device, which includes a first positioning module and a processor, and a second positioning module connected to the inspection device via wired or wireless communication. Accordingly, if Figure 1As shown, the method includes the following operations:

[0027] S110: Obtain low-precision positioning data and / or high-precision positioning data.

[0028] In this embodiment, the first positioning module is used to obtain low-precision positioning data, and the second positioning module is used to obtain high-precision positioning data. In one embodiment, the first positioning module includes at least two satellite navigation systems, such as GPS, GLONASS, Galileo, BeiDou, etc. The first positioning module can simultaneously receive signals from at least two satellite navigation systems to generate high-precision positioning data; or the first positioning module uses differential GPS (DGPS) / RTK (real-time kinematic) technology to generate high-precision positioning data. In this embodiment, the second positioning module determines the approximate location of the inspection device by identifying the unique identifier of the cellular base station to which the inspection device is connected, thereby generating low-precision positioning data; or it estimates the location by scanning the signal strength (RSSI) of Wi-Fi access points (APs) around the inspection device and matching them with a known Wi-Fi fingerprint database to generate low-precision positioning data; or the second positioning module estimates the distance based on the signal strength of Bluetooth beacons received from the external environment, and infers the location based on this to generate low-precision positioning data.

[0029] S120: Select and upload low-precision positioning data and / or high-precision positioning data according to a preset working scenario.

[0030] In one embodiment, the working scenario includes rough inspection and detailed inspection, and the selection of uploading low-precision positioning data and / or high-precision positioning data according to the preset working scenario includes: if the working scenario is rough inspection, uploading low-precision positioning data; if the working scenario is detailed inspection, uploading high-precision positioning data.

[0031] Specifically, in one embodiment, the inspector's task is to conduct inspections along the railway. Different preset work scenarios correspond to different work areas, and the different work areas include at least the railway line area and the platform area. When the inspector conducts inspections in the railway line area, the inspector's main task is to conduct a rough inspection while moving from one platform to another. That is, during the movement, the inspector observes the rails, contact network, and environment along the railway and records whether there are any dangers or damage. Therefore, under normal circumstances, there is no need to record the movement process in detail. In this case, only low-precision positioning data needs to be uploaded. When an abnormality occurs and needs to be confirmed, the specific location information or problems of the inspection need to be recorded in a timely manner. At this time, high-precision positioning data can be uploaded.

[0032] Once inspectors enter the platform area, they must perform inspections including, but not limited to, turnout inspections, fire safety checks, signal light inspections, platform door and slit light status checks, and platform environment inspections. The inspection area is large and complex, requiring timely recording of specific locations and any issues discovered. High-precision positioning data is then uploaded.

[0033] In one embodiment, the inspection device receives high-precision positioning data from the second positioning module via wireless communication. The second positioning module periodically reports the high-precision positioning data it has acquired to the inspection device according to a preset period. If the second positioning module fails to acquire high-precision positioning data, it reports null value data to the inspection device. The inspection device determines whether the positioning data is valid based on the received data. If it is confirmed that the received data is high-precision positioning data, the data is marked and temporarily stored. If it is confirmed that the received positioning data is null value data, the corresponding positioning data is set to invalid. Preferably, during a rough inspection, the inspection device only uploads or uses low-precision positioning data; during a detailed inspection, the inspection device uploads or uses valid high-precision positioning data and replaces the null value data with low-precision positioning data. This ensures the continuity of the inspection and positioning function during the detailed inspection, and prevents frequent interruptions of the inspection task due to the lack of high-precision signals.

[0034] In one embodiment, the inspection device pre-identifies the data type or data source of the uploaded high-precision positioning data so that different inspection tasks can be executed in a timely manner according to the data type during data upload or use.

[0035] In one embodiment, the operating scenario includes a high-performance mode and a low-power consumption mode, and the selecting to upload low-precision positioning data and / or high-precision positioning data according to the preset operating scenario includes: if the operating scenario is the low-power consumption mode, uploading low-precision positioning data at a lower frequency or not uploading any positioning data; if the operating scenario is the high-performance mode, uploading high-precision positioning data at a higher frequency.

[0036] Specifically, in one embodiment, the task of the inspector is to conduct inspections along the railway, and different preset work scenes correspond to different work areas, and the different work areas include at least the area along the railway and the platform area. When the inspector conducts inspections in the area along the railway, the inspector's main task is to conduct inspections while moving from one platform to another, that is, to observe the rails, contact network and environment along the railway during the movement and record whether there are any dangers or damage. Since the distance between the two platforms is relatively far, it is necessary to ensure that the inspector's location information can be obtained in real time during the inspection process, and to avoid safety problems. Considering the limited power of the inspection equipment, the working scene for inspections along the railway is a low-power mode. At this time, the inspection equipment is controlled to receive and upload low-precision positioning data at a lower frequency (data can be uploaded every 1-5 seconds, for example, once every 2 seconds), to minimize power loss and ensure that the inspector can successfully complete the inspection task. In an alternative embodiment, if the power level of the inspection device is lower than a preset threshold, a super standby mode can be activated. At this time, both the first positioning module and the second positioning module stop working to reduce power consumption. The inspection device does not need to obtain or upload any positioning data to ensure that the inspection device has the minimum power level for emergency contact communications.

[0037] In this embodiment, when the inspector enters the platform area, the inspector can charge the inspection equipment through the charging device, or use the backup battery of the inspection equipment stored in advance on the platform. Therefore, in order to efficiently complete a large number of inspection tasks in the platform area, the working scene of the inspection equipment is set to high-performance mode. At this time, the inspection equipment receives the high-precision positioning data generated by the second positioning module, and receives and uploads the high-precision positioning data to the corresponding server at a higher frequency (data can be uploaded 10-20 times per second, for example, 15 times per second) to complete more complex inspection tasks.

[0038] Compared with the prior art, in the dual positioning inspection method of this embodiment, low-precision positioning data and / or high-precision positioning data can be obtained according to the working scenario, and low-precision positioning data and / or high-precision positioning data can be uploaded according to the working scenario, thereby avoiding the problem that the inspection equipment itself cannot perform high-precision inspection tasks well when the positioning accuracy is low. At the same time, the external independently powered second positioning module can also independently provide high-precision positioning data, thereby avoiding the power consumption of the inspection equipment when the positioning function is always turned on, extending the working time of the inspection equipment, and ensuring the smooth execution of the inspection task. In addition, the method of the present application can also adjust the frequency of uploading positioning data according to different inspection tasks, further reducing the power consumption of the inspection equipment and improving the user experience of the equipment.

[0040] Figure 2This is a flow chart of a dual positioning inspection method provided by the second embodiment of the present invention. This embodiment can be applied to a dual positioning inspection device for execution. The device can be implemented by software and / or hardware and can generally be integrated into a dual positioning inspection system. The dual positioning inspection system of this embodiment includes an inspection device, which includes a first positioning module and a processor, and a second positioning module connected to the inspection device via wired or wireless communication. Accordingly, if Figure 2 As shown, the method includes the following operations:

[0041] S110: Obtain low-precision positioning data and / or high-precision positioning data.

[0042] S120: Select and upload low-precision positioning data and / or high-precision positioning data according to a preset working scenario.

[0043] S130: Generate fence warning information, where the warning information is generated based on the low-precision positioning data or the high-precision positioning data.

[0044] Specifically, after selecting to upload low-precision positioning data and / or high-precision positioning data to the server based on a preset work scenario, the server calculates whether the inspection work is within the normal range based on the received data and the preset electronic fence information of the inspection task. If the current position of the inspection device exceeds the normal range, a fence alarm message is generated and sent to the inspection device. In an alternative embodiment, the inspection device pre-receives the electronic fence information sent by the server based on the inspection task, and determines whether the current position of the inspection device exceeds the normal range based on the low-precision positioning data or high-precision positioning data. If so, a fence alarm message is generated to prompt the inspector to return to the inspection range in a timely manner to avoid getting lost during the inspection and causing safety accidents.

This embodiment can be applied to a dual positioning inspection device for execution.

Accordingly, if Figure 3 As shown, the method includes the following operations:

[0047] S110: Obtain low-precision positioning data and / or high-precision positioning data.

[0048] S120: Select and upload low-precision positioning data and / or high-precision positioning data according to a preset working scenario.

[0049] S140: Generate inspection task prompt information, where the inspection task information is generated based on the low-precision positioning data or the high-precision positioning data.

[0050] Specifically, after selecting to upload low-precision positioning data and / or high-precision positioning data to the server based on a preset work scenario, the server calculates the currently completed inspection task and the next best inspection task based on the received positioning data and the preset inspection task. It then generates prompt information for the next best inspection task and sends it to the inspection device, thereby improving the inspector's task execution efficiency. In one embodiment, the inspection device pre-receives the inspection task location issued by the server based on the inspection task, and determines whether the inspection device's current position is close to the target inspection task based on the low-precision positioning data or high-precision positioning data. If so, a first inspection task prompt is generated; if not, a second inspection task prompt is generated.

[0052] Figure 4 This is a flow chart of a dual positioning inspection method provided by the fourth embodiment of the present invention. This embodiment can be applied to a dual positioning inspection device for execution. The device can be implemented by software and / or hardware and can generally be integrated into a dual positioning inspection system. The dual positioning inspection system of this embodiment includes an inspection device, which includes a first positioning module and a processor, and a second positioning module connected to the inspection device via wired or wireless communication. Accordingly, if Figure 4 As shown, the method includes the following operations:

[0053] S110: Obtain low-precision positioning data and / or high-precision positioning data.

[0054] S120: Select and upload low-precision positioning data and / or high-precision positioning data according to a preset working scenario.

[0055] S150: Generate inspection navigation information, where the inspection navigation information is generated based on the low-precision positioning data or the high-precision positioning data.

[0056] Specifically, after selecting to upload low-precision positioning data and / or high-precision positioning data to the server based on a preset work scenario, the server calculates the optimal navigation information for the current inspection task based on the received positioning data and the preset inspection task, and sends it to the inspection device to improve the inspector's mobility efficiency. In one embodiment, the inspection device pre-receives the inspection route issued by the server based on the inspection task, and determines whether the current position of the inspection device deviates from the inspection route based on the low-precision positioning data or high-precision positioning data. If so, it generates inspection navigation information to facilitate the smooth execution of the inspection task, or adjusts the execution order of the inspection tasks and generates inspection navigation information corresponding to the updated task order to avoid inspection task failure.

The device 500 can be implemented by software and / or hardware, and can generally be integrated into a dual positioning inspection system, such as Figure 5 As shown, the device 500 includes: a data acquisition module 510 and a data upload module 520.

[0059] The data acquisition module 510 is used to acquire low-precision positioning data and / or high-precision positioning data.

[0060] In this embodiment, the data acquisition module 510 includes a first acquisition module and a second acquisition module. The first positioning module is used to acquire low-precision positioning data, and the second positioning module is used to acquire high-precision positioning data. In one embodiment, the first positioning module includes at least two satellite navigation systems, such as GPS, GLONASS, Galileo, and BeiDou. The first positioning module can simultaneously receive signals from at least two satellite navigation systems to generate high-precision positioning data.

In this embodiment, the first acquisition module receives data from the first positioning module, and the second acquisition module receives data from the second positioning module.

[0061] The data uploading module 520 is used to select and upload low-precision positioning data and / or high-precision positioning data according to a preset working scenario.

[0062] In one embodiment, the working scenario includes rough inspection and detailed inspection. If the working scenario is rough inspection, the data upload module 520 uploads low-precision positioning data; if the working scenario is detailed inspection, the data upload module 520 uploads high-precision positioning data.
