Abstract
The utility model relates to an automobile flasher flash frequency detection device which comprises a timer, a counter, a flasher, a flashlight, an alternating current power supply and an adjustable voltage stabilization power supply. The timer, the counter, the flasher and the flashlight, are electrically connected in order. The timer and the counter are respectively connected with the alternating current power supply. The flasher and the flashlight are respectively connected with the adjustable voltage stabilization power supply. In the working process of the flasher, the alternating current power supply is turned on, and the timer and the counter are started at the same time. When the timer reaches a set time, a normally closed contact of the timer is disconnected, the counter is cut off, and the channel of the voltage on both ends of the flashlight is detected. Timing counting is carried out, and the flash frequency is detected. Compared with the prior art, the automobile flasher flash frequency detection device provided by the utility model has the advantages of high detection accuracy, easy operation and the like.
Description
Technical field
The utility model relates to a kind of pick-up unit, especially relates to a kind of automobile flasher flashing rate pick-up unit.
Background technology
Flasher has important effect for automobile, and it can accurately convey to human pilot on every side with the intention of travelling of human pilot, if flasher breaks down, then will bring very big hidden danger to safe driving.At present, the employed flasher model of central electrical box is pressed the voltage classification on the passenger vehicle, mainly contains 12V, 24V; Can be divided into by control mode: monolateral control, bilateral control.For flasher, country has formulated relevant criterion.At present, my department has formulated the examination criteria of flasher according to the flasher GB.Because my department adopts manual timing to the detection of flasher at present, the judgement that is in the flasher of critical value for flashing rate is then made troubles.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of Detection accuracy high, easy to operate automobile flasher flashing rate pick-up unit for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of automobile flasher flashing rate pick-up unit, this device comprises timer, counter, flasher, flashlamp, AC power and adjustable stabilized voltage supply, described timer, counter, flasher are connected with flashlamp and are connected, described timer sum counter connects respectively AC power, and described flasher and flashlamp connect respectively adjustable stabilized voltage supply.
Described flashlamp is provided with a plurality of, and a plurality of flashlamp are connected in parallel.
The timing time that described timer is set is 60s.
Compared with prior art, the utlity model has following advantage:
(1) Detection accuracy is high: old detection method needs manually timing, and error is large.The utility model has been realized the self-clocking counting to the flasher flashing rate.
(2) the monitor station interface adopts the product repacking of this department, plug when being convenient to detect.
Description of drawings
Fig. 1 is the electrical structure schematic diagram of the utility model pick-up unit.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of automobile flasher flashing rate pick-up unit, this device comprises timer 1, counter 2, flasher 3, flashlamp 4, AC power and adjustable stabilized voltage supply, described timer 1, counter 2, flasher 3 are connected with flashlamp successively and are connected, described timer 1 sum counter 2 connects respectively AC power, and described flasher 3 is connected with flashlamp and is connected respectively adjustable stabilized voltage supply; Described flashlamp 4 is provided with a plurality of, and a plurality of flashlamp are connected in parallel.
The principle of work of above-mentioned automobile flasher flashing rate pick-up unit is: in the flasher course of work, connect AC power, timer and counter start simultaneously, 60s when timer reaches the timing time of setting, the normally closed contact of timer disconnects, cut off the path of counter detection flashbulb both end voltage, timer counter detects flashing rate.
