Analysis of the eight major test items before the industrial all-in-one PC goes on the market


Before a qualified industrial all-in-one PC is delivered to customers, which inspection procedures need to go through? The all-in-one PC has been assembled and assembled. What needs to be done before leaving the factory to ensure that it is flawless and can operate normally?

There are often 3C products on the Internet. Performance tests and unboxing videos, through running the product and showing the effect, explain the new technology and new design of the new product to consumers to achieve the test purpose. These tests are more inclined to the performance test of the product, which is different from the factory inspection of the product.

The industrial all-in-one PC will also perform performance tests. The selected test items are more stringent than those of the commercial C terminal. Common performance test items include high temperature aging, dustproof and waterproof, electromagnetic electrostatic interference, anti-drop and anti-collision, etc. In the field of industrial applications It has another name – product reliability test, which can show the industrial-grade attributes of the product from the side. Different from the performance test, the factory inspection procedure of the industrial all-in-one machine pays more attention to the integrity of the product. Generally, there are the following inspection items.

The first detection content is button function, indicator color, and boot time. The test method is to press the button several times, observe whether the color of the power indicator light is normal, and record the boot time.

The second detection content is the industrial display screen. The screen detection includes: resolution, horizontal and vertical full screen, normal display screen, and symmetrical black border of the display. By observing the screen, adjust the desktop background image, and observe whether it is abnormal.

The third test content is touch test. Here, touch sensitivity test. With the help of the desktop test software eGalax Touch, through clearing and correction, use a touch pen to draw diagonal lines. Click the start bar in the lower left corner and the hidden icon in the lower right corner to observe whether There is a delay.

The fourth system hardware configuration test, check the industrial all-in-one system configuration, CPU model, content inventory, operating system, hard disk properties, and specification partitions.

The fifth LCD screen test is to run the LCD screen test software DisplayX to check whether the red, green, blue, white and black solid colors of the screen are normal.

The sixth network cable test, check whether the network status is connected, open the browser to test.

The seventh interface test, the interface test includes USB interface; VGA, HDMI signal to the terminal, the terminal will automatically display after receiving the signal, whether the picture is clearly displayed and normal; COM port and LPT printer port test. Active identification, clear display, and normal connection are the main requirements.

The eighth sound test is to use the test headphones to test the main audio interface, which requires normal recording and normal playback.

The factory inspection is the last procedure for the listing of the industrial integrated machine. It is a routine inspection. The purpose of the inspection is to find quality problems and ensure that the products can run normally when they are delivered to customers.
