The vehicle-mounted driving data recorder is provided with a single chip, wherein the single chip is connected with a memory unit circuit and a data display unit circuit; the vehicle-mounted driving data recorder is characterized in that the single chip and a CAN (Controller Area Network) driving unit circuit are in communication connection, an signal output end of the single chip is connected with a wireless sending unit circuit, and the single chip is further connection with an USB (Universal Serial Bus) interface unit circuit.
Description
Technical field
The utility model relates to a kind of vehicle-mounted bicycle data logger.
Background technology
Visible bicycle data logger on the market is merely able to record the information such as some speed mileages, can't accurately locate the reason of fault when automobile breaks down.The drive recorder of more complicated requires the extraneous many sensors of register instrument, has increased like this car load wire harness, brings negative effect may on the contrary the security of car load.And existing bicycle data logger does not have the function of wireless transmission data.
The utility model content
Goal of the invention of the present utility model is to provide a kind of vehicle-mounted bicycle data logger, record data as required, and need not external wire harness, simultaneously can the wireless transmission data.
Realize the technical scheme of the present utility model purpose:
A kind of vehicle-mounted bicycle data logger, has single-chip microcomputer, single-chip microcomputer is connected to storage unit circuit and data display unit circuit, it is characterized in that: single-chip microcomputer is connected with the communication of CAN driver element circuit, the signal output part of single-chip microcomputer connects the wireless transmission element circuit, and single-chip microcomputer also is connected to the usb interface unit circuit.
Single-chip microcomputer is selected the MC9S12 processor.
The beneficial effect that the utlity model has:
The utility model is equivalent to original car load high-speed CAN network increases a node, thereby realizes collection and the record of various data.The data volume that can record is large, data that can not select the person to record according to the actual needs, and can record the inner parameter of TCU, ECU dispatch control system, can help like this us accurately to locate driving faults.And the utility model is provided with the wireless transmission element circuit, data in time can be sent to long-range client service center.
Description of drawings
Fig. 1 is the utility model circuit principle structure block diagram.
Embodiment
As shown in Figure 1, single-chip microcomputer (selecting the MC9S12 processor) is connected to storage unit circuit (selecting the FLASH storage chip) and data display unit circuit, single-chip microcomputer is connected with the communication of CAN driver element circuit, the signal output part of single-chip microcomputer connects the wireless transmission element circuit, and single-chip microcomputer also is connected to usb interface unit circuit (selecting CH375).
Single-chip microcomputer is realized reading of data by car load CAN network, and the computer expert crosses USB interface and realizes reading of data, simultaneously, can send data to long-range client service center by the wireless transmission element circuit.
