Description
Technical field
The present invention relates to locomotive instrumentation field, specially a kind of diesel fork lift truck intelligence instrument.
Background technique
Diesel fork lift truck instrument is essentially all mechanical hand of dial indicating water temperature and oil mass at present, and segment encode screen shows hour meter
And error code, LED light instruction alarm, without network savvy and GPS positioning function.The present invention is a intelligent diesel fork lift truck instrument
Table, this instrument show that water temperature dial plate and oil mass dial plate can be shown in color line screen with software design using 4.3 cun of color/graphics
It in curtain, is indicated without mechanical dial plate, alert icon may be displayed on color/graphics and indicate without LED light tube, hour
Meter, fault code, revolving speed, oil consumption and the description of failure Chinese can be shown in color/graphics, and the content of display interface can
With arbitrary placement, this is that segment encode screen is not accomplished.
Current color screen can realize the display of various pictorial patterns by configuration software, and technology is quite mature.It defends
Star can not position indoors, and people's most of the time is spent indoors again, and related service is not popularized, it may be said that interior is fixed
Position under cover huge commercial opportunities.In business application, according to different application scenarios, indoor positioning technologies divide consumer level and industry again
Grade.Consumption market application has: mall shopping, parking lot reverse car search, family's people's air defense are wandered away, it requires system compatible to popularize
Mobile intelligent terminal.Enterprise market application has: stream of people's monitoring and analysis, intelligence manufacture, emergency relief and personnel's asset management
Deng.The positioning accuracy request of technical grade technology is higher, operation object, individual in crowd etc. is distinguished, with special tags and biography
Sensor matches, and does not consider the compatibility with existing intelligent terminal generally.
It is largely artificial that current high-precision indoor positioning technologies are required to more expensive additional aids or early period
Processing, these all constrain popularizing for technology significantly.The location technology of low cost then needs to improve in positioning accuracy.?
The direction that cost is also indoor positioning is reduced on the basis of offer high accuracy positioning.What GPS positioning was used is satellite-signal,
Indoors, underground garage, traffic tunnel positioning signal will receive influence increase deviations, or even defend in the intensive region of cloud layer
Star signal also will receive limitation so that positioning accuracy is not high or blind location area occur；Mobile positioning technique is logical using wireless mobile
Communication network is measured a certain mobile terminal or individual in sometime locating geographical location according to specific algorithm, with
Just relevant location information service is provided for mobile terminal user, or is monitored and is tracked in real time, but its positioning accuracy is missed
Difference can be at 100 meters or more.
Therefore, existing diesel fork lift truck instrument is improved, is a good problem to study.
Summary of the invention
In the prior art existing insufficient in order to solve, the present invention provides a kind of instruments to be obtained by CAN communication
The water temperature of vehicle, oil mass, oil consumption, revolving speed and various warning messages diesel fork lift truck intelligence instrument.
The present invention is implemented as follows:
Diesel fork lift truck intelligence instrument, including internal combustion vehicle instrument by CAN communication obtain the automatically controlled water temperature of internal combustion vehicle, oil mass, oil consumption,
Revolving speed and various warning messages simultaneously show these information in 4.3 cun of color screens；Be provided in the instrument GPS positioning module and
GPRS module；
The VGUS software development that the soft dial plate of water temperature and oil mass and each alert icon AI software of the color screen are shown in；
GPS module and GPRS module are that the finished product SIM868, SIM868 bought on the market is integrated with GPS and GPRS.MCU control
What device processed was selected is STM32F Series MCU；
The diesel fork lift truck intelligence instrument built-in power module, reverse-connection preventing circuit built in power module, if anti-reverse electricity is not added
Road, if power positive cathode is reversed, circuit board chip can be burned off；
The reverse-connection preventing circuit adds a forward conduction diode S1D in power supply positive input, in this way when B+ inputs electricity
Source anode, conducting diode conducting, circuit work normally, if B+ input power cathode, conducting diode S1D is not turned at this time,
Whole circuit board is out of power not to work, but not burns circuit board, if there is no S1D conducting diode, B+ input power cathode traces
Plate will be burned out.
The method that diesel fork lift truck intelligence instrument realizes positioning, comprising the following steps:
1), GPS module receives latitude and longitude information from satellite, is transferred to MCU controller；
2), GPRS module obtains latitude and longitude information from base station, is transferred to MCU controller；
3), whether controller is effective to data by the longitude and latitude for judging GPS, if effectively, the preferential data for using GPS, and pass through
Information of vehicles and location information are uploaded to cloud platform by GPRS module；If invalid, by the GPRS longitude and latitude data obtained and
Information of vehicles uploads to cloud platform.
4), cloud platform can be communicated by GPRS and send control information to MCU controller, and MCU controller is according to phase
It is automatically controlled that information control internal combustion vehicle should be controlled.
Positive beneficial effect: the present invention is a intelligent diesel fork lift truck instrument, this instrument is aobvious using 4.3 cun of color/graphics
Show, water temperature dial plate and oil mass dial plate can be shown in color/graphics with software design, be indicated without mechanical dial plate, alarm
Icon may be displayed on color/graphics and indicate without LED light tube, in hour meter, fault code, revolving speed, oil consumption and failure
Text description can be shown in color/graphics, and the content of display interface can be with arbitrary placement, this is that segment encode screen is not accomplished.
There are also networkings and positioning function, this instrument GPS positioning module for this instrument, can acquire the latitude and longitude information of vehicle, function of networking
It can be that each parameter of instrument to collect is uploaded to platform by GSM technology, the shape of vehicle can be observed in real time on platform in this way
The long-range control of state and realization to vehicle.It is positioned in terms of positioning using GPS positioning and GPRS base station location complementation,
What GPS positioning was used is satellite-signal, and indoors, underground garage, traffic tunnel positioning signal will receive influence to increase positioning inclined
Difference, or even also will receive limitation so that positioning accuracy is not high or blind location area occur in the intensive region satellite-signal of cloud layer；
GPRS base station location precision depends greatly on the distribution of base station and the size of coverage area, and error can be more than one kilometer；It is single
Pure GPS positioning and simple GPRS base station location are all unable to complete the requirement of a specific requirements environment；So this instrument is fixed
Position is positioned using GPS and GPRS complementation, switches GPRS positioning when GPS can not be positioned.It realizes when to be in GPS signal blind for vehicle
Without the problem of GPS positioning information when area.
