Description

A vehicle multi-source information collection and transmission device

technical field

The utility model relates to a vehicle multi-source information collection and transmission device, in particular to a multi-source information collection device capable of comprehensively collecting vehicle driving information and positioning information, and a transmission device for transmitting vehicle information through bluetooth.

Background technique

Vehicle information involves driving information, such as speed, acceleration, fault code, etc., and positioning information, including longitude, latitude, heading, etc. The sources of the above information are different. Vehicle internal information such as speed and fault codes come from inside the vehicle, acceleration information needs to be obtained through external sensors, and positioning information needs GPS (Global Positioning System) and other positioning systems to obtain.

For the internal vehicle information such as speed in the above information, the current collection methods are:

1. Through GPS positioning technology, use GPS receiving equipment to analyze GPS messages and obtain speed information from them. The problem with this method is: the accuracy of the GPS system and the inaccurate collection of speed information caused by time delay. Since the update rate of GPS is generally 1HZ, there is a certain delay in the acquisition of speed information; in addition, the accuracy of the measured speed depends on positioning systems such as GPS; if a positioning system with high positioning accuracy and high update frequency is used, there will be cost issue.

2. Install sensors and acquisition equipment inside the vehicle, and measure the speed of the vehicle through the acquired signals. The problem with this method is that the vehicle needs to be refitted so that sensors and acquisition devices can be installed inside the vehicle, while refitting an existing vehicle not only involves a lot of work, but also involves the willingness of the car owner. Therefore, There is a long way to go in terms of practicability; in addition, this method needs to calibrate the speed of different vehicles, so there is a problem of universality.

3. Perform passive listening directly on the vehicle bus, and obtain the speed of the vehicle through the information in the vehicle bus. The problem with this method is that it needs to enter the vehicle bus system, which will not only have an impact on the electrical characteristics of some vehicle internal bus systems, but also require refitting the vehicle; in addition, there are many internal bus protocols in the vehicle, and it is difficult to realize the control of all types of vehicles. Acquisition of speed information has a generality problem.

For the acquisition of acceleration information and positioning information, an external system, including an acceleration sensor and a positioning system, is usually used for information collection. Application is relatively easy as no modifications to the vehicle are involved. However, whether it is vehicle internal information, or acceleration information and positioning information, the current information collection system is independent, and the application of the above information is also separated and isolated. It lacks comprehensive processing of vehicle information, so it is difficult to achieve more complex, Rich applications.

Take Fig. 8 as an example to describe the workflow of the present utility model:

When this embodiment is connected to the vehicle OBD interface, power is supplied to the entire system through J01, and U01 performs system initialization. The initialization work mainly includes: adjusting the working clock of U01 itself, setting the serial port for communicating with U02, setting the serial port for communicating with U03, setting the CAN controller for communicating with U04, setting the serial port for communicating with U05, setting the serial port for communicating with U08, Set the port for AD sampling on U07, set the port for collecting and controlling U06, and perform initial gravity acceleration settings and AD sampling settings.

U05 acquires satellite signals through cold start or hot start, and analyzes the signals through its own program, generates NMEA0183 format messages and sends them to U01 through the serial port.

After U08 is started, it establishes the RFCOMM service and waits for the connection of the external Bluetooth client. After the RFCOMM service connection with the client, U01 sends the information to U08 through the serial port, and then sends it out through U08. The information received by U08 is sent to U01 through the serial port.

When U01 is initialized, the system enters the running state.

U01 controls U02 to obtain the vehicle speed through the serial port. When initializing the KW protocol (KW protocol includes: KWP2000, ISO9141-2, KWP1281) link, if the reply from the vehicle can be obtained, the vehicle speed will be obtained through the KW protocol. If the reply from the vehicle cannot be obtained, it means that the vehicle does not have the KW OBD diagnostic protocol, and the J1850 protocol search is performed.

U01 controls U03 to obtain the vehicle speed through the serial port. When the J1850 protocol link is initialized, if the reply from the vehicle can be obtained, the vehicle speed is obtained through the J1850 protocol. If the reply from the vehicle cannot be obtained, it means that the vehicle does not have the J1850 OBD diagnosis protocol, and the ISO15765-4 protocol search is performed.

U01 controls U04 through the serial port to obtain the vehicle speed. When initializing the ISO15765-4 protocol link, if the reply from the vehicle can be obtained, the vehicle speed will be obtained through the ISO15765-4 protocol. If the reply from the vehicle cannot be obtained, it means that the vehicle does not have the ISO15765-4 OBD diagnosis protocol, and the application layer protocol packet is sent to the Bluetooth client through U08 if the vehicle OBD protocol search fails. At this point the system stops running and waits to check the connection.

When the system finds an OBD protocol and U05 has been started, the system analyzes the GPS message to obtain the latitude and longitude, direction and UTC clock of the vehicle, converts the UTC clock into the time in the current time zone, and then combines it into an application layer protocol package Send the latitude and longitude, direction and time of the vehicle to the Bluetooth client through U08. At this time, the vehicle speed is acquired through the analysis of the OBD protocol, the acceleration is acquired through the acquisition and control of U06, and the acceleration is corrected through the acquisition of U07, and the vehicle speed information and acceleration information are combined into an application layer protocol packet and sent through U08 to Bluetooth client. The system runs cyclically in this way, using the GPS message as the trigger for the information collection of the system, and using the clock in the GPS message as the time stamp.

When U01 receives the application layer protocol packet for finding error codes through U08, it stops collecting vehicle information. According to the currently used OBD protocol, scan the error code of the vehicle, combine the scanned error code into an application layer protocol packet and send it to the Bluetooth client through U08. If there is no error code, an application layer protocol packet without an error code is sent. After scanning the error code, the system will be re-initialized.
