Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of on-vehicle information display device of the utility model, comprising: power module 1, CPU2, signal processing module 3, signal input module 4, button 5 and alarm display module 6.Power module 1 comprises DC power supply 11 and power management module 12, and DC power supply 11 adopts 24V powered battery, is whole display device power supply.DC power supply 11 connects power management module 12, and power management module 12 comprises power management chip, and 24V voltage transitions is become to 3.3V voltage, offers CUP2 and is connected with it.CPU2 is connected 6 with signal processing module 3 with alarm display module respectively, and signal processing module 3 is connected with button 5 with signal input module 4 respectively, wherein, signal input module 4 comprises multi channel signals input port, in the present embodiment, comprise 32 channel signal inputs, wherein, 20 logic low limit, road inputs, 12 tunnel logic flash inputs, the other end of these signal input ports is connecting respectively the electronic monitoring equipment on vehicle, as brake shoe plate abrasion sensor, engine bin temperature sensor, storage room temperature sensor, retarder temperature sensor or rear fog lamp switch sensor.Button 5 signals carry out logical process by CPU2 and realize correlation function, can be used for the mode of operation of whole display device to switch, such as selecting to enter Auto-Sensing Mode or number of times display mode or sense channel configuration mode, in sense channel configuration mode can to the detection of some passage wherein and warning shields or.After signal entering signal processing module 3, export CPU2 to and detect, in CPU2 inside, signal is judged, and carry out logic control.
In the present embodiment, also comprise wake-up signal input end 7, connect respectively power module 12 and CPU 2.The VACC of wake-up signal input end 7 inputs, is wake-up signal, and the power management chip in power module 1 is waken up to effect; CPU2 detects VACC simultaneously, realizes the power supply of whole display device is controlled.When wake-up signal not detected, CPU starts to enter dormancy power-down mode, carries out power management.
As shown in Figure 2, be the workflow schematic diagram of the present embodiment.
First after energising, carry out self check, self check state is as follows: the LED lamp in LED warning circuit flashes successively by red, green, and every kind of color is lighted 1s; In hummer 1S, pipe after three times and close; LCD display circuit shows " start " printed words; Subsequently, enter circular wait state.
At circular wait state, the LED lamp in LED warning circuit is green Chang Liang, and indication power supply is normal; Hummer is sounding not; LCD display circuit shows " each road is normal " printed words; CPU is the signal of cycle detection signal input module and button always, if there is signal input, enters mode of operation supervisor status.
In mode of operation supervisor status, after CPU judges input signal, different according to input signal, and enter alarm mode, Auto-Sensing Mode, number of times display mode, sense channel configuration mode or dormancy power-down mode.
At alarm mode, state is as follows: the LED lamp in LED warning circuit becomes red Chang Liang; Hummer is long to be rung; LCD display circuit shows relevant warning message; DO output terminal output alarm signal, provides the running status alarm of operational vehicle critical component to backstage dispatching platform.In the present embodiment, due to LCD display circuit show limited, main display channel number, signal name and alert content.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; within not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
