[0071] Please refer to Figure 2 , shows a flow chart of an embodiment of the data collection method proposed in the present application. The embodiment of the present application can acquire and process relevant data based on artificial intelligence technology.

[0072] The data acquisition method provided in the embodiment of the present application is used in a data acquisition system, wherein the data acquisition system includes a monitoring device and a server. The data acquisition method provided in the embodiment of the present application includes the following steps:

[0073] S210, the monitoring device sends a communication request to the server.

[0074] In an optional application scenario, the monitoring device may be a vehicle-mounted device, and the vehicle-mounted device may be a vehicle-mounted camera, a vehicle-mounted video recording device, etc., which is not specifically limited here.

[0075] In this step, the monitoring device sends a communication request to the server, wherein the communication request carries a first key corresponding to the monitoring device.

[0076] S220, the server establishes a communication connection with the monitoring device when the first key matches the second key corresponding to the server. It should be noted that the server can generate the second key.

[0077] In this step, the server generates a second key based on the pre-stored information related to the monitoring device, matches the first key with the second key, and establishes a communication connection with the monitoring device when the first key matches the second key. For specific implementation methods of how to generate the second key, please refer to the subsequent embodiments.

[0078] S230, the monitoring device classifies the collected monitoring data, and sends the classified monitoring data to the server through different communication channels.

[0079] In an optional application scenario, the monitoring device is a vehicle-mounted monitoring device, which collects audio and video data in the vehicle and coordinate data of the vehicle in real time to form monitoring data.

[0080] In this step, the monitoring device collects monitoring data in real time, classifies the collected monitoring data, and sends the classified monitoring data to the server through different communication channels. Different communication channels correspond to different network transmission speeds.

[0081] Generally speaking, the network transmission speed supported by the channel for transmitting audio and video data is higher than the network transmission speed supported by the channel for transmitting text data.

[0082] S240, the server receives the classified monitoring data, and distributes and stores the monitoring data according to data categories.

[0083] In this step, after receiving the classified monitoring data, the server distributes and stores the monitoring data according to the data categories of each monitoring data, that is, the monitoring data of different data categories are stored in different databases. For specific implementation methods, please refer to the subsequent embodiments.

[0084] In the embodiment of the present application, the monitoring data is classified and sent to the server through different communication channels. The network speeds required for the above different communication channels are different, thereby reducing the requirements for network speed during the transmission of monitoring data, reducing packet loss, and thus improving the success rate of data collection. In addition, during the data collection process, the first key sent by the monitoring device and the second key corresponding to the server are compared. Only when the first key matches the second key, a communication connection between the monitoring device and the server is established, thereby ensuring communication security.

[0085] Optionally, the monitoring device sends a communication request to the server, including:

[0086] The monitoring device generates a first key name according to a device type mark and a device unique mark of the monitoring device;

[0087] The monitoring device generates a first key password according to a device type mark, a device unique mark, a device unique password, a device serial number, and a random value of the monitoring device;

[0088] The monitoring device generates a first key based on the first key name and the first key password;

[0089] The monitoring device sends a communication request carrying the first key to the server.

[0090] It should be understood that the parameters of the monitoring device include the device type mark (productKey), the device unique mark (deviceName), the device unique password (deviceSecret), the device serial number (clientID) and the random value (timestamp) and the encryption algorithm (hmacsha1).

[0091] Optionally, the device type flag can be represented by the field pK, the device unique flag can be represented by the field device, the device unique password can be represented by the field secret, the device serial number is the device SN number, and the random value is usually the time when the monitoring device requests communication.

[0092] In this embodiment, the monitoring device generates a first key name according to the device type flag and the device unique flag. Optionally, the field representing the device type flag is combined with the field representing the device unique flag to generate the first key name; for example, the generated first key name is: pk-device.

[0093] In this embodiment, the monitoring device calculates the device type mark, the device unique mark, the device unique password, the device serial number, and the random value through an encryption algorithm to generate a first key password.

[0094] For example, the hmacsha1 algorithm is used to calculate the fields representing the device type flag, device unique flag, device unique password, device serial number, and random value. The relevant pseudo code is as follows:

[0095] hmacsha1("secret","clientId12345deviceNamedeviceproductKeypktimestamp789").toHexString()

[0096] Among them, the above timestamp789 is a field representing a random value, and the above clientId12345 is a field representing a device serial number.

[0097] After the first key password and the first key name are generated, the first key password and the first key name are aggregated to obtain the first key, and the first key is carried in the communication request sent to the server. In this embodiment, the monitoring device generates the first key according to its own relevant parameters, so that in the subsequent communication connection with the server, the identity of the monitoring device can be verified by the first key, thereby improving the network security of the communication connection.

[0098] Optionally, before the server establishes a communication connection with the monitoring device when the first key matches a second key corresponding to the server, the method further includes:

[0099] The server parses the first key to obtain a first key name; the first key name includes a device type mark and a device unique mark of the monitoring device;

[0100] The server queries the unique device identifier of the monitoring device in a preset mapping table to obtain the unique device password, device serial number, and random value of the monitoring device; the mapping table stores the mapping relationship between the unique identifier and the unique password, serial number, and random value;

[0101] The server generates a second key name according to the device type mark and the device unique mark of the monitoring device, and generates a second key password according to the device type mark, the device unique mark, the device unique password, the device serial number, and the random value of the monitoring device;

[0102] The server generates a second key based on the second key name and the second key password.

[0103] In this embodiment, after receiving the first key, the server parses the first key to obtain a first key name. As described above, the first key name is obtained by combining the device type mark and the device unique mark.

[0104] The server is pre-set with a mapping table, which stores the mapping relationship between the unique mark and the unique password, serial number, and random value. In this embodiment, the server inputs the device unique mark obtained by parsing the first key into the mapping table for query to obtain the device unique password, device serial number, and random value of the monitoring device.

[0105] Furthermore, the server generates a second key name based on the device type mark and the device unique mark, and generates a second key password based on the device type mark, device unique mark, device unique password, device serial number, and random value of the monitoring device; the specific implementation method is consistent with the way the monitoring device generates the first key name and the first key password, and will not be repeated here.

[0106] After obtaining the second key name and the second key password, the second key name and the second key password are combined to obtain the second key.

[0107] In this embodiment, the server generates a second key based on the received first key and related information stored in itself, so that in the subsequent process of communicating with the monitoring device, the identity of the monitoring device can be verified by the second key, thereby improving the network security of the communication connection.

[0108] Optionally, after the server establishes a communication connection with the monitoring device when the first key matches a second key corresponding to the server, the method further includes:

[0109] The monitoring device sends a discovery message to the server at intervals of a first preset time length;

[0110] The server, upon receiving the exploration message sent by the monitoring device, sends feedback information generated based on the exploration message to the monitoring device;

[0111] The server re-establishes the communication connection with the monitoring device after a second preset time interval when the server does not receive the exploration message sent by the monitoring device;

[0112] The second preset duration is shorter than the first preset duration.

[0113] In this embodiment, after the monitoring device establishes a communication connection with the server, the monitoring device sends a discovery message to the server at intervals of a first preset time. Optionally, the discovery message is a PING message.

[0114] If the server receives the exploration message sent by the monitoring device, it sends feedback information to the monitoring device. Optionally, the feedback information is a PONG message.

[0115] If the server does not receive the discovery message sent by the monitoring device, the server re-establishes the communication connection with the monitoring device after a second preset time interval.

[0116] The second preset time length is shorter than the first preset time length. Optionally, the first preset time length is 10 seconds and the second preset time length is 5 seconds.

[0117] In this embodiment, when the monitoring device establishes a communication connection with the server, the monitoring device is controlled to periodically send exploration messages to the server to monitor the communication status between the monitoring device and the server and ensure the communication quality between the monitoring device and the server.

[0118] Optionally, after the server establishes a communication connection with the monitoring device when the first key matches a second key corresponding to the server, the method further includes:

[0141] In an embodiment of the present application, the monitoring device uses different communication channels to send monitoring data of different data types to the server. The network speeds required for the above-mentioned different communication channels are different, thereby reducing the requirements for network speed during the transmission of monitoring data, reducing packet loss, and thereby improving the success rate of data collection.
