Everyone is definitely familiar with the small, exquisite and powerful smart used in architectural automation, which is smart sensors? They are indispensable key components in our smart buildings now… If you say it wrong, they are key components! These little guys are everywhere, silently in various types – such as commercial office buildings, large shopping malls, residential buildings, and even factory buildings. Smart sensors for building automation play a particularly active and irreplaceable role in the efficiency, energy saving, comfort and safety of the entire building.
To put it simply, an intelligent sensor is a kind of information that can feel or be tested – whether it is temperature, humidity, or physical quantities such as light, slight changes in chemical composition, biological existence, or states such as motion and non-movement, converting these strange information into electrical signals that we can process according to certain rules, or even? After preliminary calculation and processing, it can be directly transmitted to the subsequent control system to make judgments and reactions, and meet certain reliability requirements and must be added to the accuracy. This requires a modern, highly integrated special… special equipment module that also has a microprocessor. Provide global procurement services for weak current intelligent products! They are the biggest difference compared to traditional old-style sensors that are so ordinary that they are. What's the biggest thing… they have their own brains, can partially process information, and can actively transmit data. They are no longer the kind of dull and wait for others to ask.
So what does intelligent sensor play in such a large building automation system… what are the main practical roles and key applications? I'll talk to you about some core points:
The first part is environmental…environmental monitoring and regulation. Like temperature sensors, humidity sensors, air quality – such as PM2.5, carbon dioxide concentration – sensors, and light sensors, they always stare at the indoor climate data and collect them without blinking. These data are given to the building control system, so that the HVAC system (that is, the kind of air conditioner ventilation) can be automatically adjusted according to the actual situation, so that the room temperature is always just right, the humidity is also comfortable, and the air quality can also be quainted; the lighting system can also be opened and closed according to the brightness of the natural light outside or adjust the brightness of the house. In this way, the comfort is not mentioned, and it can save a lot of unnecessary electricity bills!
Another big guy has to calculate how energy is effective… Effective management and energy conservation and consumption reduction. How much current is used and the voltage is stable and the power sensor is stable! How much gas, how many water, gas, electricity, and water meter are intelligently connected to the network, accurately counting the specifics of each area and each different equipment in the building, which really depends on the energy usage status of the finger. By analyzing these data, the system uncovers the areas that are very wasteful with electricity, gas, water, and then optimizes the switching time and operating power of the equipment, and moves quickly towards the energy-saving goal!
They are also indispensable for security protection. Thermal imaging probe, detector of smoke, sensors for whether doors and windows are locked normally, and the sound sensing of glass breaking all play an important role. Whenever there is any suspicious situation, such as sudden temperature rises, it may catch fire, or if the window is pried open, the sensor will immediately send an alarm message to the security system.
There is another special but quite common one left, which is (whether anyone is there). Infrared motion sensing or ultrasonic presence sensors can tell whether there are people in the room, conference room, or in the corridor and aisle, and about how many people are in the room. This information is so useful. It can make the air conditioner and lights work only when someone needs it. Why are you still on without anyone? At the same time, it can also help property managers understand what they are…, understand the real use of building space, and optimize how to arrange the space more reasonably.
Some friends may be confused and want to know more about the details? I'll try to answer a few questions:
Q: Smart sensors with different interfaces, like RS485? Or, KNX, and wireless, for example, these are really troublesome when choosing. How to choose?
Answer: This mainly depends on what kind of overall communication protocol standards and requirements are used in your building automation system, as well as the on-site tooling and wiring environment. If the wire is not so easy to pull, then wireless is definitely the first choice, right? In addition, how much data is in communication, how much data is transmitted once, how far a signal can be transmitted without interrupting data packet loss, whether there are particularly high requirements for data security, etc., these factors are considered comprehensively. Generally speaking, wiring is convenient and not short of money (can be used for dozens of meters), and wired is the most stable; don’t you want to make a big move? Temporary small areas need to be arranged flexibly? In some scenarios with small data volume, wireless solutions are very fast to install, but they are fast and fast. The stability may be discounted in complex environments. We must weigh the pros and cons! It is best to find professional and knowledgeable people, such as system integrators, and help evaluate and choose the most suitable one at once.
Q: Is it troublesome to install these small smart sensors for a long time to use and maintain them? Do they need a particularly professional technician to do it?
Answer: Nowadays, smart sensor design is becoming more and more intelligent and user-friendly. If installed, some of them are magnetically sucked, and some have hole-punched brackets that can fix the wall. Most of them should… in most cases, they can fix and wiring without complex professional skills. After installation, most of them support remote configuration parameters, remote software updates and data viewing. Pay attention to whether there are any problems with the power supply in daily life, and whether the surface of the sensor is dirty will affect performance: By the way, we provide global procurement services for weak current intelligent products! If the signal suddenly disappears or the data is inaccurate, don’t panic. First check… Check whether the connection is loose or not. If the signal is not clear, please contact the manufacturer’s technical hotline (see the 400 phone number printed above to try) and ask. Generally, minor problems can be solved. Relatively speaking, it is much easier to worry and trouble than the old-fashioned pure analog output!
My own opinion is that this kind of intelligent sensor will become more and more powerful in future building automation, and will become more and more…intelligent! They will become smaller, delicate and inconspicuous, with low power consumption that can be as low as one or two years without changing the battery, have a stronger perception of the surrounding more refined environments, and will also become a small link in the waves of the Internet of Things… The waves are surging in the intelligent ocean, making our buildings truly become a space that can perceive self-adjustment of living giant trees, which is generally flexible and green and healthy.
