Latest company news about the inspection of the outdoor advertising machine

At present, the inspection of the outdoor advertising machine is mainly divided into three parts: the chassis, the outdoor LCD high-brightness LCD screen, and the software. The specific inspection process is as follows:

1. Chassis assembly process;

1. The first thing the outdoor advertising player sees is the case, and the product is placed outdoors, so IP65 is a general international standard. Generally, check whether the glass glue on the inner side of the welded shell is uniform, and whether it is leaking in the outdoor welding seam.

2. Check the mounting bracket, whether the nut is tightly attached to the frame, and compare the mounting hole to pull it for a fixed placement.

3. Compare the case of the outdoor advertising machine, fix the nut, and carefully check the gap between the screw hole and the glass glue. If there is separation or water ingress, please disassemble the hole as soon as possible to make the waterproof glue firm.

4. Watch the surface of the whole machine clean and check whether there is dust inside the glass. Touch the inside of the glass to see if it is squeezed and flattened. Use gravity to smooth it and see if there are blisters or bubbles. If there is, it will be unqualified.

5. Open the door frame of the outdoor advertising machine and try to close the door panel with one hand. If the door panel touches the pressure strip, the door cannot be closed with force, indicating that the design of the outdoor advertising machine door frame does not meet the anti-theft standard. One is the structure of the door panel is not good, and the other is the problem with the lock assembly.

6. Look at the running noise of the machine and see whether the insulation wool on the body can insulate the machine. If the air conditioner is noisy, the insulation wool will not reflect at all. First, consider the heat dissipation structure of the air conditioner.

2. Outdoor LCD high-brightness LCD screen inspection standards;

1. According to ordinary wiping, coat the glass with a dust-free cloth to see if there are water drops around the glass. If you find glass and there are water droplets in the screw holes, please fill it with glass glue.

2. Use a caliper to measure the distance between the inside of the glass and the LCD screen. If the rubber strip exceeds 1mm, please pay attention to the air-cooled structure design.

3. Check whether the internal board of the LCD screen is clear, and whether the surface of the LCD screen is guaranteed to be free of dust and stains.

4. Carefully watch the LCD panel and the support frame, according to the direction indicated on the backlight, to see if the LCD screen is placed properly.

5. Check the fan, thermal insulation cotton, and protective net.

6. Check the drive components such as the drive board, decoder board, wiring terminal, power supply, etc., and analyze according to the standard of "Electronic Configuration Table".

3. Software debugging of customized outdoor advertising machine.

If it is a customized outdoor advertising machine, it is also necessary to debug the software of the outdoor advertising machine. For example: electronic newspaper reading software, highway toll display or network remote control, these are the functional requirements of customized outdoor advertising machines. It is different from the acceptance standards of outdoor advertising machines with conventional reserved VGI and HIMD interfaces. It has higher requirements for the reception of WIFI and 4G/5G antenna signals.
