Description

Technical Field

[0001] The present invention relates to the technical fields of vehicle-mounted TBOX wireless communication and vehicle-mounted hotspots; in particular, to the technical field of vehicle-mounted WiFi channel selection, and more specifically, to a method and system for systematic automatic channel selection of vehicle-mounted WiFi. Background Art

[0002] With the development of Internet of Things and smart Internet technology, cars, as a popular consumer product, no longer simply serve the basic function of transportation. Consumers have more demands for the practical functions of cars in work and life.

[0003] At present, the in-vehicle AP hotspot is a special Internet access device launched for new energy vehicles. The in-vehicle AP hotspot brings more convenient services to users, allowing consumers to enjoy the convenience and changes brought to life by technological development.

[0004] However, since the automatic channel scanning and selection process before turning on the AP takes a long time, which affects the AP startup time, the user terminal device needs to wait for a long time before being able to access the AP hotspot and provide network services to the terminal device, resulting in a poor user experience. Summary of the Invention

[0005] In view of this, the present invention aims to provide a systematic automatic channel selection method and system for in-vehicle WiFi. This method pre-scans the quality of in-vehicle WiFi channels in the current environment and location, statistically evaluates the busyness and interference level of each channel in the current environment, selects a channel as a preset channel, and then, based on the vehicle's current status, directly selects the preset channel in the corresponding configuration as the working channel when the vehicle activates the WiFi hotspot, and directly activates the access point (AP). This method solves the existing problem of AP channel scanning first, which affects the AP startup time and causes the AP automatic selection process to be too time-consuming. This method improves AP startup efficiency and enhances the user experience.

[0006] The present invention provides a method for automatically selecting a vehicle-mounted WiFi system channel, comprising the following steps:

[0007] S1. Write an application APP_X for channel scanning and install the application APP_X in the background system.

[0008] S2. When the vehicle is stationary and the vehicle computer or TBOX is not in sleep mode, the application APP_X runs in the background and its related threads are started. The channel scan is performed every N seconds to calculate the interference and channel quality of the relevant channels in the current environment.

[0009] S3. Set the number of pre-scans for the channel scan to three times, and record the optimal channel results obtained each time, namely OC1, OC2, and OC3; if the number of optimal channel results OC1, OC2, and OC3 of the three scans that are the same channel is greater than or equal to 2, record the same channel as the preset channel PresetChannel;

[0010] If the optimal channels OC1, OC2, and OC3 obtained from the three scans are all different, two more channel scans are performed, with the results of these two scans being Optimal Channel 4 and Optimal Channel 5 respectively. If the same channel exists in the five scans, this same channel is used as the preset channel. If the optimal channels obtained from the five scans are still different, the channel with the best signal quality among these five channels is used as the preset channel.

[0011] Set the preset channel as the current working channel of the vehicle WiFi;

[0012] S4. Storing the preset channel and recording the vehicle position and time information at that time;

[0013] For example, the format of a single vehicle location and time information record is: location (e.g., home) + current time + Preset Channel 1;

[0014] Vehicles often have fixed parking locations, such as home, work, school, frequently visited shopping malls, and hospitals. For example, if a vehicle has recently parked at "home" multiple times, then there will be preset channel records selected from multiple time points at the "work" location. In other words, a location may have multiple preset channels (e.g., preset_ch1, preset_ch2, ​​preset_ch3) at multiple time points, meaning that the information records for that location will correspond to multiple times and preset channels.

[0015] S5. When the vehicle computer or TBOX enters the dormant state, the application APP_X is exited and channel scanning is stopped to control the power consumption during dormancy. The present invention realizes the process of automatically selecting the working channel and quickly starting the AP with low power consumption.

[0016] The in-vehicle WiFi systemized automatic channel selection method of the present invention can automatically calculate and select the optimal channel for the user when the user uses the AP function of the in-vehicle WiFi, thereby accelerating the AP function activation speed, shortening the AP function activation time, and improving the user experience.

[0017] Furthermore, after step S5, if the vehicle computer or TBOX exits the dormant state but the vehicle is still stationary, the application APP_X is activated again to perform regular channel scanning and setting.

[0018] Furthermore, after the step S5, if the vehicle enters the driving state and the vehicle position changes at any time, the application APP_X is exited and the regular channel scan is no longer performed.

[0019] The application APP_X in the present invention can be activated or exited in real time according to the vehicle scenario status, does not occupy too many system resources, and can achieve accurate working channel selection and AP startup at a low operating cost.

[0020] Furthermore, when the AP is turned on for the first time and then turned on for the next time, the method for selecting the working channel includes:

[0021] If the background system can obtain the vehicle's current location information at this time, and the preset channels of multiple records of the current vehicle location within a certain time period are the same, it means that the optimal channel for this location during this period is relatively fixed. The preset channel is extracted as the working channel to directly turn on the AP without channel scanning, thereby shortening the AP function taking effect and improving the user experience.

[0022] Furthermore, when the AP is turned on for the first time and then turned on for the next time, the method of selecting the working channel further includes:

[0023] If the background system can obtain the current location information of the vehicle at this time, but the preset channels of multiple records of the current vehicle location within a certain time period are different, it means that the optimal channel for this location during this period is not fixed, and the preset channel recorded most recently is selected as the AP's working channel.

[0024] Furthermore, when the AP is turned on for the first time and then turned on for the next time, the method of selecting the working channel further includes:

[0025] If the background system cannot obtain the current vehicle's location information at this time, and the vehicle has not moved from the time of the most recently recorded preset channel to the current time, the most recently recorded preset channel will be selected as the working channel to start the AP.

[0026] Furthermore, when the AP is turned on for the first time and then turned on for the next time, the method of selecting the working channel further includes:

[0027] If the difference between the generation time of a preset channel and the current time exceeds the set time of X hours (taking into account the possibility of significant changes in the surrounding WiFi environment), the preset channel is no longer reliable. The channel pre-scan mechanism is triggered before the AP is turned on, and the scan information is saved to the storage area. The relevant historical data is updated, and the preset channel calculated by this scan is used as the pre-configuration for AP operation.

[0028] In summary, the systematic automatic channel selection method for in-vehicle WiFi of the present invention selects a relatively optimal channel as the working channel when a user uses the AP function of the in-vehicle WiFi, thereby accelerating the activation of the AP function and shortening the activation time of the AP function.

[0029] When you turn on the AP for the first time and then turn it on again, if it is a situation other than the above, for example, the background system cannot obtain the current location information of the vehicle, and the vehicle has moved between the time of the most recently recorded preset channel and the current time, then according to the original strategy, first perform channel scanning, and then select the optimal channel as the working channel to turn on the AP.

[0030] The present invention also provides a vehicle-mounted WiFi systematized automatic channel selection system, which executes the vehicle-mounted WiFi systematized automatic channel selection method as described above, including:

[0031] Create an application module: used to write an application APP_X for channel scanning, and install the application APP_X in the background system;

[0032] Start application module: When the vehicle is stationary and the vehicle computer or TBOX is not in sleep mode, the application APP_X is run in the background, the relevant threads of the application APP_X are started, and a channel scan is performed every N seconds to calculate the interference and channel quality of the relevant channels in the current environment.

[0033] Select working channel module: used to set the number of pre-scans of the channel scan to three times, and record the results of the optimal channel Optimal Channel obtained each time, namely OC1, OC2, and OC3; if the number of values ​​of the optimal channel results OC1, OC2, and OC3 of the three scans that are the same channel Channel is greater than or equal to 2, then the same channel is recorded as the preset channel Preset Channel; if the results of the optimal channels OC1, OC2, and OC3 of the three scans are all different, then two more channel scans are performed, and the results of these two scans are respectively Optimal Channel 4 and Optimal Channel 5; if the same channel exists in the five scan data, then the same channel is used as the preset channel Preset Channel; if the optimal channels of the five scans are still different, then the channel with the best signal quality among the five channels is selected as the preset channel Preset Channel; and the preset channel Preset Channel is set as the current working channel of the in-vehicle WiFi;

[0034] Storage and recording module: used to store the preset channel Preset Channel and record the vehicle position and time information at that time;

[0035] Exit application module: used to exit application APP_X when the vehicle computer or TBOX enters sleep mode and stop channel scanning to control power consumption during sleep mode.

[0036] The present invention also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the above-mentioned method for automatic channel selection of a vehicle-mounted WiFi system.

[0037] The present invention also provides a computer device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, the steps of the above-described method for automatic channel selection for a systematized vehicle WiFi are implemented.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] The method and system for systematic automatic channel selection of in-vehicle WiFi provided by the present invention pre-scans the quality of in-vehicle WiFi channels in the current environment and location, statistically evaluates the busyness and interference level of each channel in the current environment, selects a channel as a preset channel, and, based on the current state of the vehicle, directly selects the preset channel in the corresponding configuration as the working channel and directly starts the AP when the vehicle starts the WiFi hotspot. This effectively solves the existing problem of AP channel scanning affecting AP startup time and causing the AP automatic selection process to be too time-consuming, thereby improving AP startup efficiency. While the user uses the WiFi AP function to select the relatively optimal channel as the working channel, the AP function startup time is shortened, thereby improving the user experience.

[0049] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0050] The embodiment of the present invention provides a method for automatically selecting a vehicle-mounted WiFi channel system. Figure 3 As shown, the following steps are included:

[0051] S1. Write an application APP_X for channel scanning and install the application APP_X in the background system.

[0052] S2. When the vehicle is stationary and the vehicle computer or TBOX is not in sleep mode, the application APP_X runs in the background and its related threads are started. The channel scan is performed every N seconds to calculate the interference and channel quality of the relevant channels in the current environment.

[0053] S3. Set the number of pre-scans for the channel scan to three times, and record the optimal channel results obtained each time, namely OC1, OC2, and OC3; if the number of optimal channel results OC1, OC2, and OC3 of the three scans that are the same channel is greater than or equal to 2, record the same channel as the preset channel PresetChannel;

[0054] If the optimal channels OC1, OC2, and OC3 obtained from the three scans are all different, two more channel scans are performed, with the results of these two scans being Optimal Channel 4 and Optimal Channel 5 respectively. If the same channel exists in the five scans, this same channel is used as the preset channel. If the optimal channels obtained from the five scans are still different, the channel with the best signal quality among these five channels is used as the preset channel.

[0055] Set the preset channel as the current working channel of the vehicle WiFi;

[0056] S4. Storing the preset channel and recording the vehicle position and time information at that time;

[0057] In this embodiment, the format of a single vehicle location and time information record is: location + current time + PresetChannel1;

[0058] S5. When the vehicle computer or TBOX enters sleep mode, the application APP_X is exited and channel scanning is stopped to control power consumption during sleep mode. This reduces power consumption during the entire process of automatically selecting the working channel and starting the AP function.

[0059] Figure 1 The specific process of automatic channel selection of the in-vehicle WiFi system in this embodiment is shown.

[0060] This embodiment automatically calculates and selects the optimal channel for the user when the user uses the AP function of the in-vehicle WiFi, thereby accelerating the activation of the AP function, shortening the activation time of the AP function, and improving the user experience.

[0061] When the AP is turned on for the first time and then turned on for the next time, if the background system can obtain the current location information of the vehicle and the preset channels of multiple records of the current vehicle location within a certain time period are the same, it means that the optimal channel for this position during this period is relatively fixed. The preset channel is extracted as the working channel to directly turn on the AP without channel scanning, thereby shortening the AP function taking effect time and improving user experience.

[0062] At this time, the background system can obtain the current location information of the vehicle, but the preset channels of multiple records of the current vehicle location within a certain time period are different, which means that the optimal channel for this period of time is not fixed. The preset channel recorded at the most recent time is selected as the working channel to start the AP, and the optimal channel at the current time is selected as the switching channel alternative (execute as shown below). Figure 2 strategy shown).

[0063] When the background system cannot obtain the current vehicle's location information at this time, and the vehicle has not moved from the time of the most recently recorded preset channel to the current time, the most recently recorded preset channel is selected as the working channel to start the AP.

[0064] When the difference between the generation time of a preset channel and the current time exceeds the set X hours (considering that the surrounding WiFi environment may change significantly), the Preset Channel is no longer trustworthy. The Preset channel recorded most recently is selected as the working channel to start the AP. At the same time, the following steps are executed: Figure 2 The strategy shown selects the optimal channel at the current time as the switching channel candidate.

[0065] In this embodiment, when a user uses the AP function of the in-vehicle WiFi, a relatively optimal channel is selected as the working channel, thereby accelerating the activation of the AP function and shortening the activation time of the AP function.

[0066] When the vehicle computer or TBOX exits sleep mode, but the vehicle remains stationary, application APP_X is reactivated to perform regular channel scanning and configuration. When the vehicle enters driving mode and its location changes moment by moment, application APP_X is exited, and regular channel scanning is discontinued. In this embodiment, application APP_X is activated and exited in real time based on the vehicle's context, minimizing system resource consumption and reducing the operational costs of in-vehicle WiFi channel selection and AP startup.
