In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Example one
Fig. 1 is a schematic flow chart of an implementation of a voice navigation method based on bluetooth communication according to an embodiment of the present invention, as shown in the figure, the method may include the following steps:
and step S101, establishing Bluetooth connection between the navigation equipment and the Bluetooth voice equipment.
In this embodiment, the navigation device may be an electronic device with a navigation function, for example, a vehicle-mounted navigator, or a portable mobile device such as a mobile phone, a tablet computer, and an electronic watch. The navigation device can be used for navigation in the process of driving, and also can be used for navigation in the processes of walking, running, riding a bicycle, a motorcycle and the like. The user inputs parameters of departure place, destination, departure time and the like on the navigation equipment. The navigation equipment sends the parameters to a server through a network, an optimal navigation path is obtained through calculation of the server and is issued to the navigation equipment, and the navigation equipment generates voice navigation data according to the navigation path. The bluetooth voice device can be, for example, a bluetooth headset, a bluetooth speaker, or a vehicle-mounted system with a bluetooth module and a voice playing module, the bluetooth headset and the bluetooth speaker can be used for receiving a voice navigation signal of the navigation device, and the vehicle-mounted system can receive the voice navigation signal of the navigation device and GPS positioning information, and then displays the positioning of the user on a map interface of the vehicle-mounted system.
Step S102, in the navigation process, the navigation equipment detects whether the voice navigation data has abnormal playing in real time.
In this embodiment, a user needs to use a navigation function during driving, first sets a destination through a mobile phone, then plans a driving route, and plays a navigation voice through a bluetooth voice device during driving, for example, "turn right 200 meters ahead", "go straight", "turn around", and the like. And in the navigation process, detecting whether the voice navigation data has abnormal playing in real time. Because the navigation equipment and the Bluetooth voice equipment are communicated through Bluetooth, certain data loss or delay exists when data transmission is carried out through Bluetooth. For example, the voice that should be broadcasted is: "200 meters ahead turn", because appear losing the phenomenon through bluetooth transmission for the data of several words in the front are lost, and the pronunciation of reporting on bluetooth speech equipment as a result is: "turn". Thereby possibly causing the user to drive wrongly or to be overwhelmed when there is no intersection to turn. Certain driving safety hidden dangers are brought to users. Therefore, in the navigation process, whether the navigation data has abnormal playing can be judged by detecting the data transmission between the navigation equipment and the Bluetooth voice equipment. The details of how to determine whether the navigation data has the playback abnormality through data transmission will be described later.
And step S103, if the abnormal playing is detected, sending a prompt to the user.
In this embodiment, if it is determined that the voice navigation data is abnormally played by detecting data transmission between the navigation device and the bluetooth voice device, a prompt is sent to the user. For example, the reminding text containing abnormal types, such as 'delayed current navigation voice' and 'lost current navigation voice', is output on the display screen of the navigation device.
Optionally, the navigation device may vibrate the navigation device when performing the text alert, and set the background color of the display screen of the navigation device to red, or flash at a certain frequency after setting the background color to red, so as to prompt the user that the current navigation voice is incorrect. Thereby drawing the attention of the user. In the embodiment, whether the voice navigation data is abnormally played or not is detected in real time in the navigation process, and a prompt is sent to the user when the voice navigation data is detected to be abnormally played, so that the situation that the user runs according to wrong voice broadcast and unnecessary loss is caused to the user is avoided.
Example two
Fig. 2 is a schematic flow chart illustrating an implementation of a voice navigation method based on bluetooth communication according to a second embodiment of the present invention, which is based on the first embodiment. The real-time detection of whether the voice navigation data has abnormal playing specifically comprises:
step S201, the navigation equipment divides voice navigation data into a plurality of data packets;
step S202, adding serial numbers to the data packets according to a time sequence and then sending the data packets to the Bluetooth voice equipment through Bluetooth;
in this embodiment, in the navigation process, in the current position of the user, when the navigation device detects that a voice prompt, for example, "turn right 200 meters ahead", needs to be sent to the user, the navigation device splits a voice signal for outputting "turn right 200 meters ahead" into a plurality of data packets suitable for bluetooth communication. And then adding sequence numbers to the split data packets according to the time sequence. So that the Bluetooth voice device can check the integrity of the data packet after receiving the Bluetooth data packet of the voice navigation data.
Step S203, checking the continuity of the serial numbers of the received multiple data packets, and determining whether the voice navigation data is lost.
In this embodiment, when the bluetooth voice device receives a data packet sent by the navigation device, the bluetooth voice device may check the sequence number of the data packet, and when the sequence number of the received data packet is discontinuous, it is considered that a packet loss event occurs in the process of transmitting data through bluetooth. For example, the complete packet sequence number should be 1, 2, 3, 4 … … N, where N is a natural number greater than 1. If the serial numbers of the data packets received by the bluetooth voice module are 1, 2 and 4 … … N, since no 3 exists in the serial numbers, it is determined that a packet loss event occurs in data transmission. Since bluetooth can transmit hundreds of thousands of data packets when transmitting data, the occurrence of individual packet loss events does not affect the understanding of the user on the voice signal. Therefore, optionally, the number of times of the packet loss event occurring when a certain number of data packets are transmitted may be calculated, and when the number of times of the packet loss event occurring is greater than the threshold, the data is considered to be lost. If the times of the packet loss events are smaller than the threshold value, the data are not considered to be lost, and the voice navigation can be played to the user normally.
And step S204, if the voice navigation data is judged to be lost, sending a reminding signal to the navigation equipment.
In this embodiment, when it is determined that the voice navigation data is lost, the voice navigation apparatus sends a reminding signal for reminding that the data is lost to the navigation apparatus. And sending a prompt to the user after the navigation equipment receives and analyzes the prompt signal. For example, "there is a loss of current speech".
Optionally, after detecting that the voice navigation data is lost, the method further includes: and stopping sending the voice navigation data to the Bluetooth voice equipment within preset time.
In this embodiment, as described above, the voice that should be broadcasted is: "200 meters ahead turn", because appear losing the packet phenomenon through bluetooth transmission for the data of several preceding words are lost, and the pronunciation of reporting on bluetooth speech equipment is as a result: "turn". Therefore, a user may make a driving error, and since the lost data is difficult to recover, in this embodiment, if it is detected that the voice navigation data is lost, the navigation device stops sending the data packet within a preset time, so as to completely shield the incomplete voice, or the bluetooth voice device may pause playing within the preset time when it is detected that the voice signal is lost, for example, the volume of the bluetooth voice device is reduced to mute. Thereby avoiding the error of the user caused by the wrong navigation voice driving. The preset time is set by a system, and may be 5 seconds, for example. Since the playing frequency of the voice is not high during the voice navigation, and the time length of each voice segment does not exceed 5 seconds, the preset time is preferably set to 5 seconds. Thereby effectively masking the missing speech. Preventing the user from being misled by the wrong speech signal.
EXAMPLE III
Fig. 3 is a schematic flow chart illustrating an implementation of a voice navigation method based on bluetooth communication according to a third embodiment of the present invention, which is based on the first embodiment. The real-time detection of whether the voice navigation data has abnormal playing specifically comprises:
step S301, the navigation device splits the voice navigation data into a plurality of data packets.
In this embodiment, step S301 is the same as step S201 in the second embodiment, and specifically, refer to step S201.
Step S302, recording a transmission time for transmitting a first data packet of the plurality of data packets.
Step S303, after the bluetooth voice device receives the first data packet, sending a receipt signal of successful reception to the navigation device.
And step S304, recording the receipt signal receiving time when the navigation equipment receives the receipt signal.
In this embodiment, the navigation device may utilize a timing module to record the transmission time for transmitting the first data packet when the navigation device transmits the first data packet. And the Bluetooth voice equipment sends a receipt signal of successful receiving to the navigation equipment while receiving the first data packet. And when the navigation equipment receives the receipt signal, the timing module records the receipt signal receiving time. Thereby completing the recording of the signal transmission time length.
Step S305, calculating whether a time difference between the receipt signal receiving time and the sending time is greater than a preset value, and if so, determining that the voice navigation is delayed.
In this embodiment, when the time difference between the receipt signal receiving time and the sending time is small, it can be determined that the data transmission time is short, and the user can be correctly navigated. If the time difference between the receipt signal receiving time and the receipt signal sending time is large, the data transmission time is long, and voice navigation delay is likely to occur. Navigation errors may occur. Therefore, in this embodiment, by calculating the time difference between the receipt signal receiving time and the receipt signal sending time, when the time difference is greater than the preset value, it is determined that the voice navigation is delayed, and a prompt is sent to the user.
Optionally, after detecting that the voice navigation data has a delay, initiating an inquiry request for whether to reconnect the bluetooth voice device.
In this embodiment, when it is detected that the voice navigation data is delayed, a prompt may be sent to the user through the navigation device, and the user is asked whether to restart the bluetooth connection between the navigation device and the bluetooth device. The navigation device may receive voice commands from a user using a voice-controlled interface. For example, the user sends "good", "restart", etc., the navigation device automatically restarts the bluetooth connection with the bluetooth voice device. Connection of the Bluetooth equipment is restarted in a voice control mode, manual operation of a user is not needed, so that the delayed Bluetooth connection can be conveniently restarted when the user drives, and user experience of the navigation equipment is improved.
Optionally, after the initiating the inquiry request of whether to reconnect the bluetooth voice device, the method includes: if a user sends a Bluetooth connection instruction between the navigation equipment and the Bluetooth voice equipment, the navigation equipment records a current navigation task; ending the current navigation task and disconnecting the Bluetooth connection between the navigation equipment and the Bluetooth voice equipment; after the Bluetooth module is restarted, Bluetooth connection is reestablished with the Bluetooth voice equipment; and starting navigation and continuing to execute the recorded current navigation task.
In this embodiment, after the navigation device receives a voice command to restart the bluetooth connection from the user, the navigation device records the current navigation task, such as the destination, the departure point, the initial recommended route, and the like of the navigation. Then ending the current navigation task and Bluetooth connection with the Bluetooth voice equipment, and reestablishing Bluetooth connection with the Bluetooth voice equipment after the navigation equipment restarts the Bluetooth module; and then starting navigation and continuously executing the recorded current navigation task, so that after the Bluetooth connection is restarted, a user does not need to set the navigation task again, and the navigation equipment is more intelligent.
Optionally, the method further includes obtaining a position where the voice navigation data is abnormally played and a type of the abnormality; transmitting the location and the type of the anomaly to a navigation server.
In the embodiment, in order to facilitate the navigation device provider to accurately investigate the reason of the abnormal voice navigation playing. And sending the position where the abnormal playing of the voice navigation data occurs and the type of the abnormal playing to a navigation server so that a navigation equipment provider can search the position where the abnormal playing of the navigation is easy to occur according to the data provided by the user, thereby being capable of solving the problem of the abnormal navigation in a targeted manner.
