Description
Technical Field
The utility model relates to a portable power source production detects technical field, especially relates to an pilot lamp automatic testing arrangement.
Background
The portable power source, also known as a power bank, is a portable charger which can be carried about, can store electric energy and charge electronic products of handheld mobile equipment, and is particularly applied to occasions without external power supply. The main components of the device comprise: a built-in battery for electric energy storage, a circuit for stabilizing an output voltage, and a charging circuit for charging the built-in battery. In order to facilitate the user to know the residual capacity of the mobile power supply, an LED indicating lamp or a digital display screen is generally arranged on the mobile power supply, and the quantity of the residual capacity is displayed through the luminous quantity of the LED indicating lamp or the number displayed by the digital display screen. However, in the current production test process of the mobile power supply, the working state detection of the LED indicator and the digital display screen can only be observed and screened by naked eyes of a tester. Because manual detection is tired easily to lead to the testing result probably to have the error, rely on the lamp that naked eye can't accurate judgement pilot lamp and digital display screen to show degree of consistency, luminance and light colour moreover, lead to the testing result to have great not enough.
Accordingly, the prior art is deficient and needs improvement.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art, provide an pilot lamp automatic testing arrangement.
The technical scheme of the utility model as follows: provided is an automatic test device for an indicator light, comprising: the automatic testing computer is provided with a computer interface, and the testing device interface and the computer interface are connected through a connecting wire, so that the information transmission between the MCU and the automatic testing computer is realized.
Furthermore, the MCU is connected with an ADC sampling circuit, and the ADC sampling circuit is connected with an ambient light sensor and a color sensor.
Furthermore, the testing device interface and the computer interface both adopt USB interfaces.
Furthermore, the testing device interface and the computer interface both adopt UART interfaces.
Further, a darkroom is arranged on the testing device, and the ambient light sensor and the color sensor are both arranged in the darkroom.
According to the above technical scheme, the utility model discloses an environment light sensor and color sensor collect each item illumination information to pass through MCU transmission to automatic test computer with illumination information, so that operating personnel observes and judges whether there is harmfully by the operating condition of surveyed portable power source's LED pilot lamp or digital display screen, thereby replaces traditional artifical the measuring, improves the accuracy and the stability that detect, satisfies the demand that mass production detected.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the present invention provides an automatic testing device for an indicator light, including: the automatic testing computer is provided with a computer interface, and the testing device interface and the computer interface are connected through a connecting wire, so that the information transmission between the MCU and the automatic testing computer is realized. During testing, the portable power source is placed in the testing device, the testing device is started, and the MCU sends a corresponding instruction, so that the ambient light sensor and the color sensor are in an activated state. And starting the mobile power supply to enable an LED indicating lamp or a digital display screen of the mobile power supply to be lightened. When the ambient light sensor detects illumination emitted by the LED indicator lamp or the digital display screen, a corresponding electric signal is sent to the MCU. After receiving the electric signal transmitted by the ambient light sensor, the MCU calculates the corresponding illumination intensity through the electric signal, and transmits the illumination intensity information to the automatic test computer through the connecting wire for displaying and recording. Similarly, the color sensor detects the color of illumination emitted by the LED indicator light or the digital display screen, and sends corresponding electric signals to the MCU according to different detected colors. And after receiving the electric signals transmitted by the color sensor, the MCU calculates corresponding color information through the electric signals and transmits the color information to the automatic test computer through the connecting line for displaying and recording. And the automatic test computer receives the illumination intensity information and the color information transmitted from the MCU, displays the detection result in a display screen connected with the automatic test computer, and compares the detection result with a preset parameter value so as to judge whether the brightness and the light color of the LED indicator lamp or the digital display screen of the tested mobile power supply are normal or not. Simultaneously, detect simultaneously through a plurality of ambient light sensor, can judge the lamp of LED pilot lamp or digital display screen and show the degree of consistency.
The MCU is connected with an ADC sampling circuit, and the ADC sampling circuit is connected with an ambient light sensor and a color sensor. The ADC sampling circuit samples and collects electric signals sent by the ambient light sensor and the color sensor and sends the electric signals to the MCU, so that the accuracy of information acquisition is improved, and the accuracy of a test result of the testing device is ensured.
The testing device interface and the computer interface both adopt USB interfaces. The USB connection has the advantages of hot plug, unified standard, capability of connecting a plurality of devices and the like, is convenient to detect by adopting a plurality of sets of testing devices simultaneously, and improves the detection efficiency.
The testing device interface and the computer interface can also adopt UART interfaces. UART communication has the advantages of no need of clock signal, one parity check bit, changeable data packet structure, etc., and is favorable to ensure the accuracy of data transmission and the accuracy of detection result.
The testing device is provided with a darkroom, and the ambient light sensor and the color sensor are arranged in the darkroom. The detected mobile power supply is placed in a darkroom for detection, so that the influence of ambient light on a detection result is avoided, and the accuracy of detection data is ensured.
To sum up, the utility model discloses an environment light sensor and colour sensor collect each item illumination information to pass through MCU transmission to automatic test computer with illumination information, so that operating personnel observes and judges whether there is harmfully by the operating condition of survey portable power source's LED pilot lamp or digital display screen, thereby replaces traditional artifical the measuring, improves the accuracy and the stability that detect, satisfies the demand that mass production detected.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
