Accompanying drawing explanation
A kind of solid state hard disc automatic tester electrical block diagram detecting test voltage and decline that Fig. 1 provides for the present embodiment.
Embodiment
Be described further below with reference to accompanying drawing 1 pair of the utility model, but protection domain of the present utility model should do not limited with this.For convenience of description and understand the technical solution of the utility model, below illustrate that the orientation that the noun of locality used all is shown with accompanying drawing is as the criterion.
As shown in Figure 1, what the present embodiment provided a kind ofly detects the solid state hard disc automatic tester that test voltage declines and receives the power supply of input power, and can download firmware testing solid state hard disc from test computer automatically.Wherein, this tester comprises voltage detecting circuit, microprocessor, SATA connector and response apparatus, and microprocessor is connected with voltage detecting circuit, SATA connector, response apparatus respectively.Wherein, microprocessor is also connected with test computer, and microprocessor can download test firmware toward test computer, and test result is back to test computer display.Microprocessor can be single-chip microcomputer or arm processor.Microprocessor effect is herein the control module as solid state hard disc automatic tester, controls test process.Therefore microprocessor also can be replaced by the circuit structure with above-mentioned functions effect.
From input power, voltage detecting circuit detects that the voltage now supplying tester is lower than early warning value, voltage detecting circuit can produce pulse signal toward microprocessor, this pulse signal of microprocessor processes, and trigger response apparatus generation information action, to warn user.When such as response apparatus is hummer, microprocessor continues to send pulse toward hummer, makes buzzer call low-voltage be detected to point out user.When response apparatus is two LED, microprocessor continues to send pulse to the first LED, makes the first LED flashing light low-voltage be detected to point out user; Microprocessor continues to send pulse to the second LED, makes the second LED flashing light be failed to point out this test value.Therefore, the solid state hard disc value that this solid state hard disc automatic tester meeting automatic-prompting is tested by this test port is inaccurate, so that test man knows, thus provides the yield of product turnout.
As shown in Figure 2, voltage detecting circuit comprises voltage comparator U1, two resistance, voltage stabilizing diode ZD1 and diode D1, input power P1 is connected with the negative terminal of voltage comparator U1 by the first resistance R1, input power P1 is connected with the anode of voltage comparator U1 by the second resistance R2, the negative pole of voltage stabilizing diode ZD1 is connected with the anode of voltage comparator U1, the positive pole of voltage stabilizing diode ZD1 is connected to ground, the output terminal of voltage comparator U1 is connected with the positive pole of diode D1, and the negative pole of diode D1 is connected with microprocessor U2.Wherein, the rated voltage of voltage stabilizing diode ZD1 is 3.6V.The input power that the present embodiment provides is the power supply of 5V, 30A.When input power toward certain test port input voltage lower than 3.6V time, voltage detecting circuit can send pulse to microprocessor, and concrete principle is described above, is not repeated herein.The Cleaning Principle of voltage detecting circuit is introduced: in input power P1 normal power supply situation herein, the magnitude of voltage at the negative terminal place of voltage comparator U1 is be greater than 3.6V's, the magnitude of voltage at the anode place of voltage comparator U1 is 3.6V, namely preset the magnitude of voltage of 3.6V at the anode place of voltage comparator U1, externally do not export pulse due to the unilateral conduction of diode D1.When input power P1 occurs abnormal suddenly, the magnitude of voltage at the negative terminal place of voltage comparator U1 is lower than 3.6V, and therefore the output terminal of voltage comparator U1 produces positive pulse, thus produces pulse signal toward microprocessor U2.
