Abstract
The invention provides a simple vehicle CAN data display device which comprises an integrated signal processing plate based on an eight-bit single chip microcomputer and an LCD. A single chip microcomputer processing plate is provided with a simple four-line vehicle on-line diagnostics contact pin interface. The single chip microcomputer is used for setting two CAN receiving nodes of a system by programming in advance, one CAN node is used for receiving an instruction of a PC to conduct system configuration, automobile CAN network data needing to be displayed are selected, and configuration is conducted by simple calculation of data. The other CAN receiving node receives the automobile CAN network data to be displayed according to the system configuration. The single chip microcomputer is connected with an automobile diagnostics interface through the simple four-line vehicle on-line diagnostics contact pin interface, the set automobile CAN network data are received, and the automobile CAN network data are processed and then displayed on the LCD in real time.
Description
Affiliated technical field
The present invention is a kind of automobile-used simple and easy CAN data display equpment, for the online of CAN network data on automobile, shows in real time.Background technology
Automotive CAN network data are abundant, and the analysis of its CAN data generally needs special-purpose CAN to gather and display equipment.The CAN collecting device of specialty is because function is too powerful, and its price is higher, and the CAN data acquisition equipment fairly simple with some is the same, and data conventionally all need to connect notebook PC and show.
Summary of the invention
The object of the invention is to carry out real-time display automobile CAN network data with small low-cost equipment, equipment need to carry out the configuration of choosing of CAN data according to chaufeur, and shows in digital form a small amount of CAN data, for example engine coolant temperature data.
Technical scheme of the present invention: equipment mainly comprises micro controller system disposable plates and LPC read-out and easy four line automobile inline diagnosis contact pin interface.Equipment directly connects CAN line slot and the system power supply slot of automobile inline diagnosis interface by four line contact pin interface.The micro controller system disposable plates of equipment can show by CAN the configuration of data, then gathers automotive CAN network data by CAN, sends to LPC read-out and show in real time CAN data after processing.
Equipment of the present invention adopts special-purpose screened housing, and micro controller system disposable plates is placed in screened housing, and LPC read-out is placed in the front end face of screened housing; there is the button switch of an equipment power supply on side; four radiodiagnosis x contact pin interface terminals are placed in the aft end face of screened housing, and compact equipment is convenient to vehicle application.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
In figure, 1.LPC read-out, 2. button switch, 3. micro controller system disposable plates, 4. screened housing, 5. four radiodiagnosis x contact pin interface.
The specific embodiment
The present invention needs to carry out system configuration by CAN before using, and the automotive CAN network data and the data simple computation processing coefficient that need demonstration are set.The VDD-to-VSS line of four radiodiagnosis x contact pin interface 5 of equipment is connected to external 12V power supply, CAN line is linked the computer that is connected to CAN address card, open button switch 2 power supply to the device, computer sends predefined instruction and carries out equipment setting, layoutprocedure can show, by instruction, can preserve configuration result on LPC read-out 1.
After having configured, equipment can directly connect automobile inline diagnosis interface by four radiodiagnosis x contact pin interface 5, is incorporated to automotive CAN network.In car running process, equipment, according to the CAN data that collection needs are set, sends to after treatment LPC read-out 1 and shows in real time.
