Specific embodiment
Appended drawing reference: 1.1 first side plates；1.2 second side plates；1.3 third side plates；1.4 the 4th side plates；1.5 bottom plate；2.1
Top plate；2.2 white frosted glass；2.3 diffusing reflection plates；3.1 first circuit board；3.2 second circuit board；4.1 screw rod；4.2 polished rod；
4.3 sliding block；4.4 plane mirror；5.1 light intensity sensor.
A kind of traffic lights, including controller, wireless communication device, mounting box and tempered glass top plate 2.1, the peace
Mounted box includes the first side plate 1.1, the second side plate 1.2, third side plate 1.3, the 4th side plate 1.4 and bottom plate 1.5, the tempered glass
Top plate closes the top opening of mounting box, and white frosted glass 2.2, the 3.1, second electricity of first circuit board are equipped in the mounting box
Road plate 3.2, first and second circuit board are located at same level height, have bar shaped between first circuit board and second circuit board
Gap, the diffusing reflection plate 2.3 being fixed between first and second side plate above bar shaped gap, the white frosted glass position
Above diffusing reflection plate, multiple red LED lamp beads are installed on the first circuit board, are equipped on the second circuit board more
A green LED lamp bead；It is connected with polished rod between first and second side plate, bearing block, bearing block are installed at first side plate
Place is equipped with bearing, is equipped with motor at second side plate, and screw rod, the screw rod 4.1 are connected between motor shaft and bearing
Sliding block is passed through with polished rod 4.2, sliding block 4.3 has the threaded hole cooperated with screw rod and the smooth hole with polished rod cooperation, the sliding block
It is fixedly connected with plane mirror 4.4, the angle of the plane mirror and vertical direction is 45 degree；First side plate it is interior
Side has blind hole, has light intensity detector 5.1 in the blind hole.
Multiple red LED lamp bead rectangular array distributions, multiple green LED lamp bead rectangular array distributions.It is described unrestrained anti-
Penetrating plate is rectangle, and width is greater than 10cm, is less than 15cm.The first circuit board and second circuit board are rectangle, and width phase
Width Deng, first circuit board is greater than 30cm.The blind hole is cylindrical hole, and the depth of the blind hole is greater than 10cm.
Further, the controller can control the traffic lights and execute fault detection mode, the failure inspection
In survey mode, controller control sliding block moves between the first position and the second position；Controller is controlled in the detection
In mode, when the measured value of light intensity detector is greater than setting duration beyond the duration of Intensity threshold range, make the nothing

Under normal circumstances, the red LED lamp bead on first circuit board light or second circuit board on green LED lamp
Pearl lights, as shown in Fig. 2, the light of LED lamp bead passes through the reflection of diffusing reflection plate, some meeting vertical irradiation is in plane reflection
It on mirror, then is reflexed in blind hole by plane mirror and is detected by light intensity detector, be not that first circuit board is opened, just theoretically
That second circuit board is opened, the measured value of light intensity detector should always in threshold range, during sliding block is mobile, though
The measured value of right light intensity detector, which has, a little to be changed, but all in threshold range.Unless break down, the first and second circuit board
Open simultaneously, or simultaneously close off or the first and second circuit board on the damage of a big chunk LED lamp bead, these failures can all lead
Cause light intensity detector biggish deviation occur, thus and alarm, maintenance is provided.Why Rule of judgment is write as and " works as light intensity
When the measured value of detector is greater than setting duration beyond the duration of Intensity threshold range ", it is because switching in traffic lights
In the process, it is possible that the case where the first and second of short duration circuit board opens or closes simultaneously, such case duration is very
It is short, in order to avoid false alarm, using duration as Rule of judgment, for very short time the case where exceeding Intensity threshold range
It does not alarm.
Although the present invention is illustrated and has been described with regard to preferred embodiment, it is understood by those skilled in the art that
Without departing from scope defined by the claims of the present invention, variations and modifications can be carried out to the present invention.
