Abstract
The utility model discloses a general outer accuse lamp array detection circuit of examining test table of four car combination meter in state, branch road more than being provided with at least all the way, parallelly connected forming between each branch road, route fuse, toggle switch establish ties and form, fuse one end warp restraint to connect the outer accuse lamp interface in the circuit that awaits measuring, and toggle switch's stiff end is connected to the other end, toggle switch's normally closed contact ground connection, toggle switch's normally open contact connection 24V power. The advantage lies in: adopt hand switch to carry out the artificial detection that the lamp was controlled outward to the instrument, artificial hourglass detects at present when having avoided original automatic control switch, has strengthened the stability that the system detected, has increased the detecting reliability of instrument to a certain extent. Adopt manual toggle switch, replaced relay before, practiced thrift the design cost. Control the lamp outside each way on, the retrieval fuse of having established ties to prevent that the instrument from controlling the lamp short circuit outward and causing occurence of failures such as system power supply damage.
Description
Technical field
This utility model relates to a kind of testing circuit, particularly relates to the state four general monitor station of automobile combination meter
External control lamp array detection circuit.
Background technology
Automobile instrument detecting system mainly can simulate automobile and send to automobile instrument in true driving process
Various signals, thus drive the various display devices of instrument to realize corresponding display, it is right thus to reach
The function of instrument and performance carry out the purpose detected.In state four commercial vehicle combination instrument, often it is provided with
Substantial amounts of external control LED (by gauge internal control, therefore can not claim external control lamp) shows for vehicle-state
Show, as left and right turn display lamp, exhaust brake indicator lamp, parking checking STOP display lamp, headlamp and
Rear lamp etc., it is controlled by the hand switch on vehicle body mostly.For this type of external control lamp on combination instrument
Detection, needs to be provided for instrument the switching signal of external control switch by detector.Original instrument external control lamp array
Detection is realized electrical switch by Micro Controller Unit (MCU) driving relay, by comparison and detection platform and the instruction of instrument to be detected
The concordance of lamp on/off judges that instrument function is the most normal.This type of method has certain Aulomatizeted Detect, but
It is that detection person is easily caused some display lamp missing inspection often due to energy is not concentrated during detection.
Utility model content
It is an object of the invention to provide a external control lamp array detection electricity for state four automobile instrument monitor station
Road, for providing the switching signal of external control switch for instrument to be detected, manually toggle switch implements instrument
The detection of status lamp.
The technical solution of the utility model is:
The external control lamp array detection circuit of the general monitor station of state four automobile combination meter, it is characterised in that include
It is provided with the branch road on more than at least one tunnel, is formed in parallel between each branch road；Described route electric fuse, stirs
Switch is in series, described electric fuse one end external control lamp interface in wire harness connects circuit under test, the other end
Connecting the fixing end of toggle switch, the normally-closed contact ground connection of toggle switch, the normally opened contact of toggle switch connects
24V power supply.
The utility model has the advantage of:
1. use the hand switch to carry out the artificial detection of instrument external control lamp, it is to avoid during original automatic control switch
Artificial missing inspection occurs, enhances the stability of system detection, adds the detection of instrument to a certain extent
Reliability.
2. use manual toggle switch, the relay before instead of, save design cost.
3., on the external control lamp of each road, resettable fuse of having connected, to prevent instrument external control lamp short circuit from causing
The accidents such as system power supply damage occur.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model；
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be readily apparent from effect
Understand, below in conjunction with diagram and specific embodiment, this utility model is expanded on further.
Testing circuit includes the branch road being provided with more than at least one tunnel, is formed in parallel between each branch road；Described
Route electric fuse, toggle switch are in series, and described electric fuse one end is outside wire harness connects in circuit under test
Control lamp interface, the other end connects the fixing end of toggle switch, the normally-closed contact ground connection of toggle switch, stirs out
The normally opened contact closed connects 24V power supply.
Instrument external control lamp array detection circuit, can be different because meter status lamp quantity to be detected is different, and one
As up to 50 external control lamps of instrument, combination instrument detector achieves 60 paths of LEDs external controls altogether, each
It is connected in parallel to each other between road and forms.As it is shown in figure 1, list 5 tunnel instrument external control lamp array detection electricity therein
Road, it is by resettable fuse F1, F2, F3, F4, F5, toggle switch S1, S2, S3, S4, S5
Constitute.
Wherein, F1-F5 all uses the resettable fuse of the 20mA/60V of 0603 encapsulation, for external control
Lamp detection branch provides overcurrent protection.
S1-S5 all uses 3 ends 102 toggle switch (simply connected) of 6A 125V to turn round son switch, is used for detecting
Member's manual operation switch, it is achieved the manual detection of external control lamp.
The normally opened contact of switch S1-S5 connects 24V power supply, normally-closed contact ground connection, and its fixing end is by recovering
Electric fuse F1-F5 is respectively connected to LED1-LED5, LED1-LED5 and is connected to instrument to be detected by rat tail
The corresponding external control lamp interface of table.For the negative control external control lamp lamp of instrument to be detected, (gauge internal is this paths of LEDs
Lamp provides positive supply), then toggle switch gets to normally-closed contact, then this negative control lamp is lighted, and toggle switch is got to often
Open contact, then this negative control lamp extinguishes；In like manner, for the just control external control lamp lamp (gauge internal of instrument to be detected
Ground is provided for this paths of LEDs lamp), then toggle switch gets to normally opened contact, then this negative control lamp is lighted, and stirs out
Normally-closed contact is got in pass, then this negative control lamp extinguishes.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.
Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-described embodiment
With description described in principle of the present utility model is simply described, without departing from this utility model spirit and model
On the premise of enclosing, this utility model also has various changes and modifications, and these changes and improvements both fall within requirement and protect
In the range of this utility model protected.
