Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.
The network taxi appointment is short for network taxi appointment. The network appointment vehicle may include a taxi, a tailgating vehicle, a express vehicle, a special vehicle, and the like. In the network car appointment scenario, after a passenger loses a used device on a car, the passenger usually contacts a platform customer service after finding that the device is lost, the platform helps to judge the position of the device by checking the positioning position reported by the device, and then a caller driver asks whether the device for picking up the passenger exists. However, on one hand, since the Positioning accuracy is not accurate enough in general, it is difficult to describe the accurate position of the device by using Positioning, and the device relies on GPS (Global Positioning System) for Positioning, and may not obtain the Positioning position due to network reasons, resulting in Positioning failure; on the other hand, the passenger can contact the platform after finding the device is lost by himself, and the time for finding the device is possibly long after the device is lost, so the timeliness is poor.
In the embodiment of the invention, the second client sends out a wireless communication signal in the order established by the first client and the second client, the first client receives the wireless communication signal, if the first client receives the wireless communication signal sent by the second client after the order is finished, the equipment where the passenger side is located is considered to be possibly lost on the vehicle, and the first client sends a loss notification to the server, so that whether the equipment where the passenger side is located is lost can be detected more timely and more accurately.
The first client is one of the passenger end and the driver end, and the second client is the other of the passenger end and the driver end. The passenger end can be an APP (application) used by the passenger, and can also be an APP used by the passenger to establish a related order with the tour taxi after the passenger signs the taxi to get on. The driver end can be an APP used by the driver, and can also be a vehicle-mounted intelligent taxi end of a tour taxi. The server can be the corresponding server of the APP and the vehicle end. The device where the passenger end is located can be a mobile phone, a tablet computer, a wearable device and the like.
The following examples are provided for the purpose of illustrating the present invention.
Referring to fig. 1, a flowchart illustrating steps of a device loss detection method according to an embodiment of the present invention is shown. The device loss detection method shown in fig. 1 is performed at the second client.
As shown in fig. 1, the device loss detection method may include the steps of:
And 102, the second client sends out the wireless communication signal.
And establishing an order between the first client and the second client, enabling the driver to arrive at the starting point, enabling the passenger to get on the bus, enabling the order to start, enabling the driver to arrive at the terminal point, and enabling the order to end.
In the embodiment of the present invention, it is noted that after the order is finished, whether the first client receives the wireless communication signal sent by the second client, so that the second client may start to generate the wireless communication signal and send the wireless communication signal at a preset time point after the order is finished. For example, the second client may start generating and sending out the wireless communication signal when the order is finished, or the second client may start generating and sending out the wireless communication signal when the preset time length is reached after the order is finished, and so on. Any suitable value may be set for the specific value of the preset duration according to practical experience, which is not limited in the embodiment of the present invention.
In the embodiments of the present invention, any suitable wireless communication signal may be used. For example, the Wireless communication signal may be an ultrasonic signal, a WIFI (Wireless Fidelity) signal, a bluetooth signal, or the like.
Referring to fig. 2, a flowchart illustrating steps of a device loss detection method according to an embodiment of the present invention is shown. The device loss detection method shown in fig. 2 is performed at the first client.
As shown in fig. 2, the device loss detection method may include the steps of:
The first client may start receiving the wireless communication signal at a preset time point after the order is finished, corresponding to the wireless communication signal generated and sent by the second client. For example, the first client may start receiving the wireless communication signal when the order is finished, or the first client may start receiving the wireless communication signal when a preset time period is reached after the order is finished, and so on. The preset time duration may be the same as the preset time duration corresponding to the time when the second client generates and sends the wireless communication signal.
The wireless communication signal received by the first client may not be from the second client. For example, if the wireless communication signal is an ultrasonic signal, the first client may also receive the ultrasonic signal sent from the outside due to external noise interference and other influences. Therefore, after the order is finished, if the first client receives the wireless communication signal, it needs to determine whether the wireless communication signal is sent by the second client. After the wireless communication signal is sent by the second client, it may be considered that the distance between the second client and the first client is short, and the device where the passenger is located may be lost on the vehicle, so the first client may send a loss notification to the server, where the loss notification is used to indicate that the device where the passenger is located may be lost. After receiving the loss notification, the server may perform corresponding processing.
Referring to fig. 3, a flowchart illustrating steps of a device loss detection method according to an embodiment of the present invention is shown. The device loss detection method shown in fig. 3 is performed at the server.
As shown in fig. 3, the device loss detection method may include the steps of:
And after receiving the loss notification sent by the first client, the server acquires the result of whether the equipment where the passenger side is located is lost. For example, the server may determine that the device where the passenger is located is lost after receiving the loss notification sent by the first client, or the server may perform further verification operation after receiving the loss notification sent by the first client, and obtain a more accurate result of whether the device where the passenger is located is lost according to the verification result.
In the embodiment of the invention, based on the network car booking scene, the first client and the second client are both positioned in the network car booking and have close distances, so that the first client and the second client can receive and transmit wireless communication signals. If the passenger does not lose the equipment where the passenger end is located on the vehicle after the order is finished, the first client does not receive the wireless communication signal sent by the second client after the order is finished, therefore, if the first client receives the wireless communication signal sent by the second client after the order is finished, the equipment where the passenger end is located is considered to be possibly lost on the vehicle, and the first client sends a loss notification to the server, so that whether the equipment where the passenger end is located is lost can be detected more timely and more accurately.
Next, the method for detecting device loss according to the embodiment of the present invention is introduced based on the whole interaction process of the driver side, the passenger side, and the server side, in view of the situation that the first client side is the driver side and the second client side is the passenger side.
Referring to fig. 4, a schematic diagram of a device loss detection process according to an embodiment of the present invention is shown. As shown in fig. 4, the device loss detection process may include: after the order begins, the passenger side requests a verification code, and the driver side also requests a code; after the order is finished, the passenger end starts to send the wireless communication signal, the driver end starts to receive the wireless communication signal, and the driver end judges whether the equipment where the passenger end is located is lost.
Referring to fig. 5, a flowchart illustrating steps of another device loss detection method according to an embodiment of the present invention is shown. As shown in fig. 5, the device loss detection method may include the steps of:
in step 501, the passenger side obtains the verification code from the server side.
The passenger side can send the verification code acquisition request to the server side at any time point from the beginning of the order to the end of the order. The identification of the passenger terminal and the like can be carried in the verification code acquisition request sent by the passenger terminal.
The driver side can send a verification code acquisition request to the server side at any time point from the beginning of the order to the end of the order. The verification code acquisition request sent by the driver end can carry the identifier of the driver end and the like.
The server side receives the verification code acquisition request sent by the passenger side and the verification code acquisition request sent by the driver side respectively, then generates verification codes and sends the verification codes to the passenger side and the driver side respectively.
In an optional implementation manner, the service end respectively analyzes the verification code obtaining request to obtain an identifier of the passenger end and an identifier of the driver end, and then queries the corresponding orders of the passenger end and the driver end to obtain a timestamp generated by the orders. And performing Hash calculation based on the identifier of the passenger end, the identifier of the driver end and the timestamp generated by the order to obtain the verification code.
Fig. 6 is a schematic diagram of a procedure for generating a verification code according to an embodiment of the present invention. As shown in fig. 6, first, raw data is acquired: id of the passenger side (i.e. identification), driver id (i.e. identification) and order generation timestamp, the raw data needs to be guaranteed to be unique for each order. Then, a 4 to 8-bit PIN (Personal Identification Number) authentication code is calculated using a hash algorithm on the original data. The PIN verification codes calculated by the Hash algorithm are distributed uniformly, the repetition probability is low, and two adjacent orders of the same driver do not have the same verification codes.
In step 504, the passenger end starts sending out the wireless communication signal after the order is finished.
The passenger end can start to generate the wireless communication signal at a preset time point after the order is finished and send the wireless communication signal. In the embodiment of the invention, the passenger terminal generates a wireless communication signal containing the verification code and sends out the wireless communication signal containing the verification code. For the specific process of generating the wireless communication signal containing the verification code, the generation of the related codes can be performed according to practical experience, and the embodiment of the present invention is not discussed in detail herein.
In step 505, the driver starts receiving the wireless communication signal after the order is finished.
The terminal of the driver can start to receive the wireless communication signal at a preset time point after the order is finished.
In an alternative embodiment, the determining whether the wireless communication signal is sent by the second client comprises: analyzing the wireless communication signal, and judging whether the wireless communication signal contains the verification code; and after the verification code is judged to be contained in the wireless communication signal, determining that the wireless communication signal is sent out by the passenger terminal.
Considering that the ultrasonic communication technology is mature, the ultrasonic communication technology is characterized by good cross-platform performance and proper distance transmission, and the transmission distance is about 0-20 m. Ultrasonic wave is because the communication that transmission distance's restriction ratio is fit for more private scene, and in the net car appointment scene, the driver passenger all is in the car, is a more private scene, consequently is comparatively fit for carrying out ultrasonic communication, and most net car appointments all have the recording function moreover, are fit for ultrasonic signal's discernment more. Therefore, the wireless communication signal in the embodiment of the present invention may be an ultrasonic signal.
The ultrasonic analysis process firstly needs to convert an analog signal into a digital signal, and then obtains the loudness and frequency of the ultrasonic through Fourier transform. Generally, ultrasonic analysis is used to identify the signal with the highest loudness, which is considered as the target information of the current communication. The defects are that the ultrasonic wave identification method is easily interfered by noise, real information cannot be found, and particularly, the external noise is large in a network car reservation scene, so that the ultrasonic wave identification rate is reduced.
Fig. 7 is a schematic diagram of an ultrasonic resolution process of the prior art. As shown in fig. 7, assuming that a noise band of 23kHz to 25kHz is identified, 20kHz is noise, if only a signal with the highest loudness is identified, a group of signals circled in an ellipse in fig. 7 is identified, and therefore the identified signal is only noise, and ultrasonic waves cannot be identified.
In view of the above problem, in the case that the wireless communication signal is an ultrasonic signal, the embodiment of the present invention proposes that the judgment on the loudness correlation is added in the ultrasonic analysis process, and not only the frequency with the highest loudness is selected. In an implementation, the analyzing the wireless communication signal and determining whether the wireless communication signal includes the verification code may include: converting the wireless communication signal to obtain the frequency and loudness of the wireless communication signal; selecting a starting signal with loudness greater than preset loudness, selecting a target signal which is behind the starting signal and has loudness difference with the starting signal smaller than a preset difference value, and dividing the starting signal and the target signal into a group of signals; judging whether each group of signals contains the verification code or not; determining that the authentication code is included in the wireless communication signal when the authentication code is included in at least one set of signals. For the specific values of the preset loudness and the preset difference, any applicable value may be selected according to practical experience, which is not limited in the embodiment of the present invention.
Fig. 8 is a schematic diagram of an ultrasonic analysis process according to an embodiment of the invention. As shown in fig. 8, fourier transform is performed on the ultrasonic signals in the 3 time periods t0, t1, and t2, and corresponding frequencies and loudness are obtained. Starting from the frequency and the loudness in the time period t0, selecting a starting signal with the loudness greater than the preset loudness (for example, the preset loudness is 30), and selecting a signal corresponding to (25khz, 65) as the starting signal; selecting a target signal from the t1 time period and the t2 time period, wherein the difference between the loudness of the start signal (25kHz, 65) and the loudness of the start signal is smaller than a preset difference value (for example, the preset difference value is 10), selecting a signal corresponding to (23kHz, 70) from the t1 time period as the target signal, and selecting a signal corresponding to (24kHz, 73) from the t2 time period as the target signal; dividing (25kHz, 65) in the time period t0, (23kHz, 70) in the time period t1 and (24kHz, 73) in the time period t2 into a group of signals; selecting a starting signal with loudness greater than a preset loudness (for example, the preset loudness is 30) from the frequency and the loudness in the t1 time period, and selecting a signal corresponding to (25khz, 34) as the starting signal; selecting a target signal with the loudness difference with the starting signals (25kHz, 34) smaller than a preset difference value (for example, the preset difference value is 10) from the t2 time period, and selecting a signal corresponding to (23kHz, 36) from the t2 time period as the target signal; (25kHz, 34) in the t1 time period and (23kHz, 36) in the t2 time period are divided into a set of signals.
Fig. 9 is a schematic illustration of ultrasonic loudness and frequency relationship according to an embodiment of the present invention. As shown in fig. 9, the circled portion in the rectangular frame is a selected group of signals, the difference between the loudness of the group of signals is small, and the selected signals are more accurate.
And step 507, after judging that the wireless communication signal is sent by the passenger end, the driver end sends a second loss notification to the server end.
After judging that the wireless communication signal is sent by the passenger end, the driver end considers that the equipment where the passenger end is located is possibly lost on the vehicle, so the driver end can send a second loss notification to the server end, and the loss notification is used for indicating that the equipment where the passenger end is located is possibly lost. After the driver end judges that the wireless communication signal is not sent by the passenger end, the driver end considers that the equipment where the passenger end is located is not lost on the vehicle, so the driver end does not need to send a loss notice to the server end.
And step 508, after receiving the second loss notification, the service end sends a prompt instruction to the passenger end.
And after receiving the second loss notification, the server responds to the second loss notification to obtain the result of whether the equipment where the passenger side is located is lost. Alternatively, the service end may confirm that the device where the passenger end is located is lost after receiving the second loss notification sent by the driver end, or the service end may perform further verification operation after receiving the second loss notification sent by the driver end.
In case the server performs a further verification operation, the second loss notification is used to instruct the server to send a prompt instruction to the passenger. Therefore, after receiving the second loss notification sent by the driver, the server sends a prompt instruction to the passenger end, wherein the prompt instruction is used for instructing the passenger end to display prompt information for the passenger to confirm whether the device is lost.
And 509, after receiving the prompt instruction sent by the server, the passenger side displays the prompt information.
If the passenger operates the prompt message and confirms that the equipment is not lost, an unremoved event is triggered and confirmed; if the passenger does not operate the prompt message and the unconfirmed device is not lost, the unconfirmed event is not triggered. And after receiving the event of confirming that the prompt message is not lost triggered, the passenger side sends a command of confirming that the prompt message is not lost to the server side, otherwise, the passenger side does not send the command of confirming that the prompt message is not lost to the server side. In the embodiment of the invention, the prompt message can continuously show the first preset time at the passenger end so as to provide the time for the passenger to confirm.
Fig. 10 is a schematic diagram illustrating a display prompt according to an embodiment of the present invention. As shown in fig. 10, the message "please confirm that the mobile phone is not lost" is displayed in the pop-up prompt box of the passenger end, and a "confirm" button is provided. After clicking the 'confirmation' button, the passenger triggers the prompt message to confirm the non-loss event, and after receiving the confirmation non-loss event triggered by the prompt message, the passenger sends a confirmation non-loss instruction of the prompt message to the server.
If the server receives the instruction of confirming that the prompt message is not lost, which is sent by the passenger end, within the first preset time, the server can confirm that the equipment where the passenger end is located is not lost. If the server does not receive the instruction of not losing the prompt message confirmation sent by the passenger terminal within the first preset time, the server informs the passenger service to make a call to the passenger terminal so as to inquire whether the passenger equipment is lost.
In step 511, the service end determines that the device where the passenger end is located is lost when the call is not answered.
When the call is not answered, the server can confirm that the equipment where the passenger side is located is lost. The server can contact the driver to inform the driver to store the passenger's equipment, and subsequent passengers seek for convenient repayment. When the call is answered, if the passenger answering device is not lost, the server can confirm that the device where the passenger end is located is not lost.
And step 512, the passenger end stops sending the wireless communication signal when the order is finished and the second preset time length is reached.
For the specific values of the first preset time length and the second preset time length, any applicable value may be set according to practical experience, which is not limited in the embodiment of the present invention. The first preset time length is less than the second preset time length.
FIG. 11 is a schematic diagram of an apparatus for receiving ultrasound without loss of the apparatus, in accordance with an embodiment of the present invention. As shown in fig. 11, when the passenger gets off the vehicle, that is, when the order is finished, the driver starts the ultrasonic recognition, and after the order is finished for a minutes (a minutes represents a second preset time period), the driver ends the recognition. During the identification period, the ultrasonic wave emitted by the passenger end is not identified, and the equipment where the passenger end is located is confirmed not to be lost.
FIG. 12 is a schematic diagram of an apparatus for receiving ultrasound in the event of loss of the apparatus in accordance with an embodiment of the present invention. As shown in fig. 12, when the passenger gets off the vehicle, that is, when the order is finished, the driver starts the ultrasonic recognition, and after the order is finished for a minutes (a minutes represents a second preset time period), the driver ends the recognition. During the identification period, the ultrasonic waves sent by the passenger end are identified, a loss notification is sent to the server end after the ultrasonic waves sent by the passenger end are identified, the server end carries out verification, the user confirmation time of b minutes (b minutes represents a first preset time) exists, and whether the equipment where the passenger end is located is lost or not is confirmed after the verification.
According to the embodiment of the invention, the loss of the equipment of the passenger can be sensed in time, the method is more accurate than positioning, the identification of the ultrasonic wave in a noise environment can be enhanced, and the accuracy of the detection of the loss of the equipment is improved.
Next, the method for detecting device loss according to the embodiment of the present invention is introduced based on the whole interaction process of the driver side, the passenger side, and the server side, in view of the situation that the first client side is the passenger side and the second client side is the driver side.
Referring to fig. 13, a flowchart illustrating steps of another device loss detection method according to an embodiment of the present invention is shown. As shown in fig. 13, the device loss detection method may include the steps of:
In step 1302, the server obtains the verification code from the server.
And step 1303, the server generates verification codes and respectively issues the verification codes to the passenger side and the driver side.
In step 1304, the driver starts sending wireless communication signals after the order is finished.
In step 1305, the passenger end starts to receive the wireless communication signal after the order is finished.
In step 1306, after the passenger end finishes the order, if the wireless communication signal is received, it is determined whether the wireless communication signal is sent by the driver end.
After the passenger end judges that the wireless communication signal is sent by the driver end, the passenger end considers that the equipment where the passenger end is located is possibly lost on the vehicle, so that the passenger end can display prompt information for the passenger to confirm whether the equipment is lost. The prompt message may be continuously presented at the passenger for a first predetermined duration to provide time for passenger confirmation. After the passenger end judges that the wireless communication signal is not sent out by the driver end, the passenger end considers that the equipment where the passenger end is located is not lost on the vehicle, so the passenger end does not need to display prompt information.
When the passenger side does not receive the event of confirming that the passenger side does not lose within the first preset time length, a first loss notification is sent to the server side; otherwise, the passenger end does not send the first loss notification to the server end.
In step 1309, the service end receives the first loss notification and then makes a call to the passenger end.
And after receiving the first loss notification, the server responds to the first loss notification and acquires the result of whether the equipment where the passenger side is located is lost. Alternatively, the service end may confirm that the device where the passenger end is located is lost after receiving the first loss notification sent by the passenger end, or the service end may perform further verification operation after receiving the first loss notification sent by the passenger end.
In the case where the server performs a further authentication operation, the first loss notification is used to instruct the server to place a call to the passenger. Therefore, the service end makes a call to the passenger end after receiving the first loss notification sent by the passenger end.
In step 1310, the service end confirms that the device where the passenger end is located is lost when the call is not answered.
In step 1312, the passenger end stops receiving the wireless communication signal when the second preset time length is reached after the order is finished.
For the specific process of each step in fig. 13, the specific description of each step in fig. 5 may be referred to.
