Controller 13, is connected with first control circuit 11 and second control circuit 12, for controlling alarm lamp 10；
Wherein, first control signal is sent to first control circuit 11 and sent to second control circuit 12 in controller 13
During second control signal, alarm lamp 10 is lighted.
Alarm lamp 10 in the embodiment of the present disclosure can be arbitrarily can be by applying in both ends (first end and second end)
Control signal, the device for lighting it, for example, alarm lamp 10 can be light emitting diode, etc..Each component of vehicle can be with
An alarm lamp 10 is corresponding with, for example engine is corresponding with an alarm lamp 10, storage battery is corresponding with alarm lamp 10, etc.,
Corresponding alarm lamp 10 can be lighted in corresponding component failure.
Controller 13 in the embodiment of the present disclosure can be the controller that can arbitrarily send binary-level signal, example
Such as, it can be MCU (Microcontroller Unit, micro-control unit) of RH850 series of auspicious Sa, etc..Controller 13
Can have multiple control signal delivery outlet, using different delivery outlets respectively with first control circuit 11 and second control circuit 12
Connection, just can send two path control signal to first control circuit 11 and second control circuit 12 at the same time.Controller 13 can obtain
Know that the fault condition of various vehicle components, such as vehicle can carry out vehicle self-test when powering on, controller 13 can according to the result of self-test
To know either with or without trouble unit, and which component failure is.When vehicle is there are during trouble unit, controller 13 can
Alarm lamp 10 corresponding with trouble unit is controlled to light by exporting first control signal and second control signal.
For example, after vehicle is via power up self-test, it is found that oil level is too low, controller 13 can be too low to instruction oil level
Alarm lamp 10 exports first control signal and second control signal, and then the alarm lamp 10 for controlling oil level too low is lighted.
Alternatively, alarm lamp 10 can be light emitting diode, then first end is the cathode of alarm lamp 10, and second end is report
The anode of warning lamp 10.First control circuit 11 includes first switch component 110, and first switch component 110 is in first control signal
Under the action of so that the cathode of alarm lamp 10 is low level；Second control circuit 12 includes second switch component 120, second switch
Component 120 is under the action of second control signal so that the anode of alarm lamp 10 is high level.
That is, controller 13 controls lighting for alarm lamp 10 by controlling the level at light emitting diode both ends, and the disclosure is real
Apply in example, alarm lamp 10 sends first control signal, to second control circuit to first control circuit 11 at the same time in controller 13
It is lit during 12 transmission second control signal, therefore, adds the condition for lighting alarm lamp 10, preferably avoid 10 quilt of alarm lamp
The situation that mistake is lighted.
Alternatively, first switch component 110 is triode or field-effect tube, and the second switch component 120 is triode
Or field-effect tube.Certainly, first switch component 110 and second switch component 120 can also be other switch blocks, as long as energy
Enough have the function that switch.
Triode can be PNP type triode, or can also be NPN type triode；Field-effect tube can be N-type field effect
Ying Guan, or can also be p-type field-effect tube, the embodiment of the present disclosure is not construed as limiting this, below will be to possible first switch
The situation of component 110 and second switch component 120 is illustrated.
Alternatively, first switch component 110 and second switch component 120 are NPN type triode.
The collector (C poles) of first switch component 110 is connected with the cathode of alarm lamp 10, the hair of first switch component 110

Close component 120 and send second control signal, C poles and the E poles of control second switch component 120 are ended, so that the sun of alarm lamp 10
Extremely high level.
Circuit connecting relation as shown in Figure 2,13 delivery outlet GPIO_1 of controller are connected with first control circuit 11, control
13 delivery outlet GPIO_2 of device is connected with second control circuit 12, then controller 13GPIO_1 can be made to export high level signal
(first control signal) is so that the C poles of first switch component 110 are turned on E poles, so that the cathode of alarm lamp 10 is low electricity
It is flat.Meanwhile controller 13GPIO_2 is made to export low level signal (second control signal) so that the C poles of second switch component 120
End with E poles, second switch component 120 is in cut-off state, and the anode of alarm lamp 10 is in high electricity because of access power supply+at this time
It is flat.That is, when controller 13GPIO_1 exports high level and GPIO_2 output low levels, alarm lamp 10 is lighted.As it can be seen that controller 13
Need output two path control signal to control lighting for alarm lamp 10, avoid because of 13 1 delivery outlet failures of controller and point
The generation of the phenomenon of bright alarm lamp 10.
Alternatively, vehicular meter alarm lamp control system further includes sample circuit 14, with controller 13 and alarm lamp 10

Voltage between pole and E poles (is applied to the current value I of C poles in the disclosureCFor a fixed value, the voltage between C poles and E poles can
By searching for ICWith VceqBetween correspondence obtain).
Due to R in practical applications2、R3、VF、VceqValue be probably a scope, for example the Standard resistance range of a resistance is
± 2 Ω of 100 Ω, therefore, pass through R3×(VF+Vceq)/(R2+R3) value that calculates is there is also value range, therefore, if collection
The voltage V of circuit collectionadIn the value range, it is believed that sampled data meets preset condition, and alarm lamp 10 works normally；
, whereas if VadNot in the value range, it is believed that sampled data is unsatisfactory for preset condition, alarm lamp 10 or alarm lamp 10
Place circuit may break down.In this way, controller 13 can know that alarm lamp 10 whether there is failure, realize to alarm lamp 10
The monitoring of working status.

One switch block, for example be triode or field-effect tube, Fig. 2 is by taking NPN type triode as an example.When controller 13 monitors A/D ends
When the use data that mouth receives are unsatisfactory for preset condition, GPIO_3 mouthfuls of output high level signals (the 3rd control letter can be passed through
Number), and then alarm components 150 are lighted, to prompt driver's alarm lamp 10 failure.In this way, in alarm lamp 10 or alarm lamp 10
During the fault of place, driver can also be known in time, be conducive to further overhaul alarm lamp 10, while also improve vehicle
Security.
Alternatively, first switch component 110 and second switch component 120 are N-channel field-effect tube.
The drain electrode (D poles) of first switch component 110 is connected with the cathode of alarm lamp 10, the source electrode of first switch component 110
