Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobiles, and in particular to a screen projection information processing method and device, an equipment and a storage medium. BACKGROUND

[0002] Automobiles are important means of transportation in modern society. When using an automobile to travel, a user often projects a mobile phone onto a car machine to better use the applications on the mobile phone, increase the safety and convenience of driving, and take advantage of the large screen and convenient operation of the car machine. For example, the car machine can display the interface of the navigation software in the mobile phone more clearly, or use the music, telephone and other applications in the mobile phone more conveniently after screen projection.

[0003] The mobile phone can search for the signal of the car machine by using Bluetooth and the like, and then establish a connection with the car machine for screen projection. At present, the process of manually projecting the mobile phone onto the car machine is relatively cumbersome, and automatically outputting a screen projection message after detecting the Bluetooth signal of the car machine will cause repeated notifications and waste of resources. Therefore, how to efficiently output the screen projection message while reducing resource waste to guide the user to project the screen has become a problem to be solved. SUMMARY

[0004] One purpose of the present application is to provide a screen projection information processing method, device, equipment and storage medium. In a case where it is determined that the time difference between the current searched device and the search time of the historical searched device is greater than a preset threshold, the device identifier is added to the screen projection candidate table, and the screen projection message is output. The advantage is that in the case where the rejection screen projection instruction for the device is received, and the signal of the device is searched again within a short time (less than the preset threshold), the screen projection message can not be output repeatedly, the number of repeated notifications is reduced, and the occupied resources are saved.

[0005] Another purpose of the present application is to provide a screen projection information processing method, system, device and storage medium.

[0023] The embodiments of the present application provide a screen projection information processing method, system, device and storage medium. In order to more clearly describe the scheme of the present application, the method provided by the present application will be introduced below in combination with the drawings. Please refer to Figure 1 , Figure 1 A flowchart of a screen projection information processing method provided by an embodiment of the present application. As shown in Figure 1 , the method includes but is not limited to the following steps:

[0024] Step 110, obtaining a first device identifier of a first device searched currently and a first search time;

[0025] The step can be performed by a terminal of a user, which can be a mobile phone, a tablet computer, or the like portable device. The first device can be a car machine of a vehicle, or the like. The terminal and the first device both open Bluetooth functions, the terminal searches for a Bluetooth signal existing around, and the first device sends a Bluetooth signal and can be searched. The first device can be any one of one or more than one device searched by the terminal. After the terminal searches for the Bluetooth signal sent by the first device, a first device identifier of the first device is acquired, and a first search time when the first device is searched is acquired. Specifically, the first device identifier can be a Bluetooth device name of the first device. For example, if a brand of a vehicle where the first device is located is A brand, the first device identifier can be "CAR A".

[0026] In step 120, a historical search table is acquired, which is used to record device identifiers of devices searched historically.

[0027] The terminal has recorded and stored the device identifiers of the devices searched historically in the historical search table before a current time. After the first device is searched currently, the historical search table is acquired. As shown in Table 1, the historical search table can record the device identifiers of the devices searched historically by the terminal and corresponding historical search times.

[0028] Table 1

[0029] Device ID Historical search time Device ID 1 Historical search time 1 Device ID 2 Historical search time 2 "CAR B" 20201103 8:25:41 … …

[0030] In step 130, it is judged whether a second device identifier matching the first device identifier exists in the historical search table.

[0031] The terminal compares the device identifier in the historical search table with the first device identifier, judges whether the second device identifier matching the first device identifier exists in the historical search table, that is, judges whether the first device is a device searched historically by the terminal.

[0032] In step 140, if the second device identifier exists, a second search time corresponding to the second device identifier is acquired, and it is judged whether a time difference between the first search time and the second search time is greater than a preset threshold.

[0033] Specifically, when the second device identifier matching the first device identifier exists in the historical search table, the second search time corresponding to the second device identifier is obtained from the historical search table. Then, it is judged whether the time difference between the first search time and the second search time is greater than a preset threshold. That is, when it is determined that the first device is a device searched by the terminal in history, the time when the first device is searched by the terminal currently and in history is compared, and it is judged whether the time difference is greater than the preset threshold. The preset threshold can be preset, and the preset threshold can be set to be greater than the search time interval of the terminal for signal searching. For example, the terminal searches every 10 seconds, the search time interval is 10 seconds, the preset threshold can be set to 5 minutes, or can be set to other values greater than 10 seconds, which is not limited in the present application.

[0034] Further, after obtaining the second search time corresponding to the second device identifier, the second search time corresponding to the second device identifier in the historical search table can also be updated to the first search time. That is, the historical search time corresponding to the device identifier in the historical search table is updated, so as to ensure that the historical search time saved in the historical search table is the time when the device is searched last time from the current time. In this way, when the terminal and the device both start Bluetooth, if the terminal searches the signal of the device at a fixed time interval, the time difference between the search time when the device is searched this time and the search time when the device is searched last time is a fixed value, which is equal to the search time interval of the terminal, and the time difference is less than the preset threshold, the device identifier of the device will not be added to the screen projection candidate table, that is, the terminal will not output the screen projection message for indicating projecting the display interface of the terminal to the display of the device. Or, the time difference between the search time when the device is searched this time and the search time when the device is searched last time is not a fixed value, but the time difference is still less than or equal to the preset threshold, so the device identifier of the device will not be added to the screen projection candidate table, that is, the terminal will not output the screen projection message. In this way, if the screen projection message has been output once and the rejection of screen projection instruction is received when driving, the terminal searches the signal emitted by the device again after a certain time interval (the time interval is less than the preset threshold), and the screen projection message is no longer output repeatedly, thereby reducing the number of repeated output of the notification and saving the occupied resources.

[0035] Step 150, if greater, the first device identifier of the first device is added to the screen projection candidate table;

[0036] Specifically, if the time difference between the first search time and the second search time is greater than the preset threshold, the first device identifier of the first device is added to the screen projection candidate table. The screen projection candidate table is used to record the device identifier of the candidate device, and one of the candidate devices can be projected to display the display interface of the terminal.

[0037] Furthermore, if the time difference between the first search time and the second search time is less than or equal to a preset threshold, the first device identifier of the first device will not be added to the screen projection candidate table, that is, for the same device that is searched multiple times in a short period of time (within the preset threshold duration), repeated output of screen projection messages for the device is avoided.

[0038] Optionally, if there is no second device identifier that matches the first device identifier in the historical search table, that is, the first device is searched for the first time by the terminal, then the first device identifier of the first device can also be added to the screen projection candidate table as a candidate device. If the terminal only searches for the signal of the first device, then the device can be determined as the target screen projection device, and the screen projection message can be automatically output, so that after the vehicle-related signal is searched for the first time, the screen projection message can be automatically output to avoid manual operation, so as to guide the user to perform screen projection, thereby improving the efficiency of screen projection. Furthermore, when the first device identifier is added to the screen projection candidate table, the historical search table can also be updated, that is, the first device identifier and the search time for the first device are added to the historical search table, and the search record of the first device is saved, so as to avoid repeated output of the screen projection message for the device when the device is searched again within a short time (within the preset threshold time).

[0039] Optionally, adding the first device identifier of the first device to the screen projection candidate table includes: obtaining the signal strength of the first device; when the signal strength is greater than the signal strength threshold, adding the first device identifier and the signal strength to the screen projection candidate table. The greater the signal strength of the first device, the closer it is to the location of the terminal. At this time, the greater the possibility that the first device will become a candidate device, and the first device identifier and signal strength can be added to the screen projection candidate table. When the signal strength of the first device is small (less than or equal to the signal strength threshold), the first device identifier and signal strength are not added to the screen projection candidate table, that is, the device identifier and signal strength information of the device with smaller signal strength do not need to be saved, which can save resources. Among them, the signal strength threshold can be pre-set according to the distance. For example, the signal strength value of the device within 2 meters of the terminal can be determined as the signal strength threshold, and this application does not impose any restrictions on this. As shown in Table 2, the device identifier and corresponding signal strength of the candidate device can be recorded in the screen projection candidate table, wherein the signal strength recorded in the table is greater than the signal strength threshold.

[0040] Table 2

[0041] Device ID Signal strength Device ID 3 Signal strength 1 Device ID 4 Signal strength 2 "CAR C" -60 dBm … …

[0042] Step 160: Determine the target screen projection device according to the screen projection candidate table and output the screen projection message.

[0043] The screen projection message output by the terminal is used to indicate whether the display interface of the terminal is allowed to be projected to the target screen projection device, and thus the target screen projection device is one of the candidate devices, and the target screen projection device can be determined from the screen projection candidate table.

[0044] Specifically, the process of determining the target screen projection device according to the screen projection candidate table can include: obtaining a historical screen projection table, the historical screen projection table being used to record device identifiers of historical screen projection devices.

[0045] The screen projection candidate table is matched with the historical screen projection table, that is, it is determined whether the candidate devices in the screen projection candidate table are historical screen projection devices.

[0046] In a case where there is a matched device identifier between the screen projection candidate table and the historical screen projection table, the target screen projection device is determined according to the number of the matched device identifiers, that is, there is a historical screen projection device in the candidate devices, and thus the device is more likely to be the target screen projection device, and the number of the historical screen projection devices in the candidate devices can be one or more than one, and the manner of determining the target screen projection device can be different in the case where the number is different.

[0047] Further, the process of determining the target screen projection device according to the number of the matched device identifiers can include:

[0048] In a case where the number of the matched device identifiers is one, the device indicated by the matched device identifier is determined as the target screen projection device, that is, there is only one historical screen projection device in the candidate devices, and thus the device is more likely to be the target screen projection device, and the device can be determined as the target screen projection device. In this way, when a plurality of device signals are searched, the only historical screen projection device in the plurality of devices can be determined as the target screen projection device, that is, the vehicle of the user can be accurately found among the vehicles corresponding to the plurality of devices (the vehicle of the user is more likely to be the historical screen projection device compared with other vehicles), the user is quickly guided to perform screen projection, and the screen projection efficiency is improved.

[0049] In a case where the number of the matched device identifiers is greater than 1, a device indicated by a third device identifier in the matched device identifiers is determined as the target screen projection device, the third device identifier being a device identifier corresponding to the largest historical screen projection time in the matched device identifiers. That is, in a case where there is more than one device in the candidate devices that has a historical screen projection, the device with the largest historical screen projection time, i.e., the device that has performed screen projection most recently, is more likely to be the target screen projection device, and the device can be determined as the target screen projection device. In this way, in a case where signals of multiple devices are searched, and at least two devices in the multiple devices have historical screen projection, the device with the most recent historical screen projection can be determined as the target screen projection device, i.e., in the multiple devices, the vehicle corresponding to the device with the most recent historical screen projection can be accurately found (compared with a vehicle corresponding to a device that is not frequently used recently, the vehicle corresponding to the device that is used recently has a historical screen projection time closer to the current time), and the user is quickly guided to perform screen projection, thereby improving the screen projection efficiency. As shown in Table 3, the historical screen projection table can record the device identifier of the device with historical screen projection and the corresponding historical screen projection time.

[0050] Table 3

[0051] Device ID Historical casting time Device ID 5 Historical casting time 1 Device ID 6 Historical casting time 2 "CAR D" 20201103 8:26:05 … …

[0052] Optionally, in a case where the screen projection candidate table and the historical screen projection table do not have matched device identifiers, a device indicated by a fourth device identifier in the screen projection candidate table is determined as the target screen projection device, the fourth device identifier being a device identifier corresponding to the largest signal strength in the screen projection candidate table. That is, in a case where none of the candidate devices has historical screen projection, the device with the largest signal strength is generally closest to the location of the terminal, and the device is more likely to be the target screen projection device, and the device can be determined as the target screen projection device.

[0053] After the target screen projection device is determined and the screen projection message is output, the terminal receives a feedback instruction of the user for the screen projection message, and the feedback instruction includes one of an allow screen projection instruction and a reject screen projection instruction. If the allow screen projection instruction is received, the terminal projects the display interface to the target screen projection device, and updates the historical screen projection table. The process of updating the historical screen projection table can include: in a case where the device identifier of the target screen projection device does not exist in the historical screen projection table, the device identifier of the target screen projection device and the screen projection time are added to the historical screen projection table. In a case where the device identifier of the target screen projection device exists in the historical screen projection table, the historical screen projection time corresponding to the device identifier of the target screen projection device in the historical screen projection table is updated to the screen projection time. In this way, the historical screen projection time recorded in the historical screen projection table is always the latest, thereby improving the accuracy of finding the target screen projection device, and further improving the screen projection efficiency. If the reject screen projection instruction is received, the terminal closes the screen projection message display window and does not perform screen projection.

[0054] The following takes a specific application scenario as an example to introduce the specific process of implementing the screen projection information processing method provided in the application embodiment.

[0055] After the user gets into the car and ignites, the car machine in the user's car is turned on with Bluetooth, and the user's terminal is also turned on with Bluetooth. The terminal automatically starts searching for the Bluetooth signals emitted by the car machines around. In this scenario, the car machines of other cars around the user's car also emit Bluetooth signals. Then, the terminal acquires the device identifier M of the car machine of the user's car and the device identifier N of the car machine of the other car, as well as the current time P, and acquires the historical search table to determine whether there are device identifiers matching the device identifiers M and N in the historical search table. Next, in different situations, corresponding operations are performed. The following introduces two possible situations:

[0056] 1) In one situation, there is the device identifier M in the historical search table, but there is no device identifier N. Then, the historical search time Q corresponding to the device identifier M is acquired, and it is determined whether the time difference between the current time P and the historical search time Q is greater than a preset threshold. If it is determined that the time difference is greater than the preset threshold, the device identifier M is added to the screen projection candidate table, and the device identifier N is also added to the screen projection candidate table. Then, the historical screen projection table is acquired, and the screen projection candidate table is matched with the historical screen projection table. It is determined that there is a device identifier matching the device identifier M in the historical screen projection table, but there is no device identifier matching the device identifier N. Then, the device indicated by the device identifier M, i.e., the car machine in the user's car, is determined as the target screen projection device, and a screen projection message is output to prompt the user whether to allow the display interface of the terminal to be projected to the display of the car machine in the user's car.

[0057] 2) In another situation, there are both the device identifier M and the device identifier N in the historical search table. Then, the historical search time Q corresponding to the device identifier M and the historical search time R corresponding to the device identifier N are acquired. It is determined whether the time difference between the current time and the historical search time is greater than a preset threshold. If it is determined that the time difference between P and Q is greater than the preset threshold, and the time difference between P and R is also greater than the preset threshold, the device identifier M is added to the screen projection candidate table, and the device identifier N is also added to the screen projection candidate table. The historical screen projection table is acquired, and the screen projection candidate table is matched with the historical screen projection table. It is determined that there are device identifiers matching the device identifiers M and N in the historical screen projection table. Then, the historical screen projection times corresponding to the device identifiers M and N are acquired. If the historical screen projection time corresponding to the device identifier M is greater, the device indicated by the device identifier M, i.e., the car machine in the user's car, is determined as the target screen projection device, and a screen projection message is output to prompt the user whether to allow the display interface of the terminal to be projected to the display of the car machine in the user's car.

[0058] In the above two situations or other possible situations, the terminal determines the target screen projection device and outputs a screen projection message to guide the user to cast the screen. However, if a screen projection rejection instruction is received, it means that the user does not need to project the terminal's display interface to the car display in his car at this time. Then, after the terminal searches for the signal of the device again at a fixed search time interval, it determines that this device is a historically searched device, obtains the time when the device was searched this time and the time when the device was searched historically, and determines whether the time difference between the two is greater than a preset threshold. Since this time difference is equal to the search time interval, it can be determined that the time difference is less than the preset interval, and this device will not be added to the screen projection candidate table, so the screen projection message for the device will not be output. That is, after receiving the screen projection rejection instruction for the previously output screen projection message, the terminal continuously searches for the signal sent by the car display in the car. Implementing the screen projection information processing method provided in the embodiment of the present application can reduce the number of times screen projection messages are output and save occupied resources. As Figure 2 As shown, Figure 2 This is a schematic diagram of the scenario, where terminal 210 is the user's terminal and device 220 is the target projection device.
