介绍
In today’s technological age, automatic monitoring devices have penetrated into all aspects of our lives, from factory workshops to greenhouses to traffic intersections. These “smart eyes” silently guard our safety and efficiency.
However, there is a question you may never have thought about: how do these monitoring devices display complex data to us intuitively? The answer is single color LED screens.
目录
1. What is an automatic monitoring device?
An automatic monitoring device is a high-tech “smart eye” that can automatically see, hear, and feel various things, and then turn the information it sees into data and transmit it back.
For example, it can measure air quality, traffic flow, and even the temperature of the machine, and it does not require people to stay by the side all the time; it can do it by itself.
Generally, the automatic monitoring device and the LED display screen are put together, just like putting a “simple coat” on the data.
For example, environmental monitoring data is directly converted into numbers or charts through the LED屏幕, which everyone can understand at a glance, which it convenient and worry-free.
One of the great benefits of this combination is “real-time update”. Just like traffic flow monitoring, the monitoring device quickly transmits the latest data to the LED screen, and the information on the screen is refreshed immediately.
Traffic managers and drivers can adjust strategies in time according to the latest information to make travel smoother.
For managers, LED display screens are like a “powerful assistant”. Through the display screen, managers can understand the “health status” of the equipment in real time.
Find problems and make decisions in time, and can also monitor remotely to make management easier.
In terms of environmental monitoring, displaying data in public places can allow residents to intuitively understand the environmental conditions and stimulate their environmental awareness.
In the field of public safety, fire monitoring data is displayed on LED screens to remind everyone to pay attention to safety, and can also provide evacuation information at critical moments, making everyone feel more secure.
2. Application scenarios of single color LED screens in automatic monitoring devices
1). Environmental monitoring
In the field of environmental monitoring, single color LED screens are like “little environmental guards”. It can show key data such as temperature, humidity, and gas concentration in real time.
For example, in a factory workshop, workers can take a look at the display screen to know whether there are any harmful gases exceeding the standard in the air and whether the temperature is appropriate.
If it is placed in a greenhouse, farmers can easily control the temperature and humidity in the greenhouse, and heat and ventilate when necessary.
So that crops can grow comfortably. This display is simple and clear, and can be understood at a glance, which is very convenient.
2). Industrial production
In industrial production, a single color LED screen is very powerful; it is simply the “health report card” of the equipment.
It can clearly display the operating status of the equipment, and parameters such as the speed and temperature of the machine can be updated in real time.
If there is a minor problem with the equipment, the display will immediately sound an alarm and flash the fault information, so that the maintenance personnel can immediately find the problem and repair it in time.
In addition, it can also display the production progress, so that managers can clearly know the operation of the production line, adjust the production plan in time, and ensure the smooth progress of production.
3). Safety monitoring
Speaking of safety monitoring, the single color LED screen is a “safety sentinel”.
It can display the status of each monitoring point in real time, such as whether the access control system is normal and whether the fire escape is blocked.
Once there is an abnormal situation, such as the fire alarm being triggered, the display will immediately display the alarm information, reminding everyone to take measures to ensure safety.
This timely reminder can avoid many safety accidents.
3. How to choose a single color LED screen suitable for automatic monitoring devices?
1). Clear 观看距离 and bright environment
You have to first figure out how far the audience is from the display. If the audience is close, such as in the workshop, use a display with a small dot pitch (such as P10, P8) to see clearly.
If the audience is far away, such as on the side of the road, you have to use a large dot pitch (such as P16, P20) so that people far away can also see clearly.
Ambient light is also critical. The indoor brightness is 300cd/㎡ to 800cd/㎡, and the outdoor 亮度 must be at least 5000cd/㎡, otherwise you can’t see anything when the sun shines.
It would be better if the brightness could be adjusted automatically, so that it can be adjusted according to the light, which is both energy-saving and clear.
2). The screen size and 解决 must be appropriate
The screen size and resolution must be based on the content to be displayed. If the content is simple, such as temperature and humidity data, a small screen will do.
If the content is complex, such as detailed parameters of the equipment’s operating status, a large screen is required so that all information can be displayed clearly.
Although single color LED screens do not require particularly high resolution, the resolution cannot be too low, otherwise the displayed text and numbers will be blurred.
Generally speaking, the smaller the dot pitch and the higher the resolution, the better the display effect.
3). Waterproof and dustproof are important
If the display is to be placed outdoors or in a humid and dusty place, waterproof and dustproof functions are very important.
The waterproof level must be at least IP55, which can prevent rain and dust from running into the display, affecting the display effect and even damaging the equipment.
If the environment is particularly harsh, such as the seaside or a chemical plant, a higher protection level may be required, such as IP65 or IP67.
In addition, the display must be able to work normally in a temperature range of -25°C to +65°C; otherwise, it is easy to have problems in extreme weather.
4. 注意事项
First, find a suitable place to install the display. If it is installed outdoors, you have to choose a place that can be sheltered from wind and rain, and it is best to avoid direct sunlight。
Otherwise, the screen will be too bright and dazzling, and it will also waste electricity.
If it is installed indoors, don’t install it in a humid or water-filled place, such as near the bathroom.
Also, ensure that the display screen is ventilated; otherwise, the heat cannot be dissipated, and it is easy to break.
Be careful when wiring. The power cord and signal cable cannot be connected incorrectly, otherwise the display screen or monitoring device may be burned.
It is best to connect the wires according to the instructions, and the joints must be tightened and not loose; otherwise, poor contact will cause problems.
If you don’t understand, it is best to ask a professional for help; don’t mess around by yourself.
If the display screen is installed outdoors or in a dusty place, waterproof and dustproof features are very important.
When installing, you can add a waterproof cover or a dust cover to the outside of the display screen.
If the display screen itself is not waterproof and dustproof enough, you must regularly clean the dust and rain to prevent water from entering or too much dust from accumulating inside.
After installation, be sure to test carefully. First, check whether the display screen can display data normally and whether the displayed content is accurate.
Then, test whether the brightness adjustment function of the display screen is normal under different ambient light conditions.
If you find a problem, adjust or repair it in time; don’t wait until it is officially used to find the problem.
5. 结论
Through today’s introduction, I believe you have a deeper understanding of the application of single color LED screens in automatic monitoring devices.
This seemingly simple display screen actually has great power. It not only makes data display intuitive, but also improves our work efficiency and quality of life.
