As population constant growth, city changes a process to accelerate, and climate change becomes people the problem of principal attention, increase ceaselessly to energy-saving architectural demand, also increasing ceaselessly to intelligent architectural demand. Be in the United States only, commerce builds the sources of energy that waste to occupy the 19% above of American total the sources of energy. 27% what HVAC system occupies the sources of energy to use an amount, illume is occupied 31% , because this utmost ground reduces commercial architectural the sources of energy,make dosage can produce very big effect.

Be in the United States, commerce builds the sources of energy that waste to occupy the 19% above of total the sources of energy, because this utmost ground reduces commercial architectural the sources of energy,make dosage can produce very big effect.

? It is OK to build and transform a project through carrying out " intelligence " the technology will save the sources of energy. Among them a technology isTake up sensor. Take up sensor is used increasingly at saving illume gentle to connect the sources of energy of air conditioning system, the easy that raises habitant is measurable. And they also are installed easily, use and safeguard.

But how to use take up sensor will save the sources of energy? What is their practical effect? Will they bring into unique structure or be worth in the project? Next we will be discussed in detail take up sensor is what, their advantage, defect or safe problem, they are economic how many the sources of energy and they save the sources of energy actually.

? WhatBe to take up sensor?

Take up sensor (also call athletic sensor, existence sensor or empty buy sensor) it is surveillant physics space in order to decide this space is medium whether the sensor of somebody. Wh some of which still has number statistic function (computation sensor and athletic sensor) . Take up sensor can receive architecture system repeatedly, and according to the space in whether somebody will open or shut illume or warm an air conditioning (HVAC) . If be willing, illume also can be moved according to taking up the circumstance undertakes dark (depend on the lamp is adjustable smooth) .

For example, so called two class attune is in a parking lot solely extraordinary popularity, because shut lamplight completely in such space not to manage,think, but tone still can help a parking lot save the sources of energy solely. Substantially, two class attune is to show acquiescent circumstance falls to be lamplight setting low brightness solely, but should detect when motion, the brightness of the lamplight in the space can increase.

Take up sensor is used at detecting to build a system to whether should be opened not only, shut or adjust, still use at data to collect. When taking up sensor collects data, if these data get be usinged correctly, it also can use a help people improves productivity and efficiency. For example, take up sensor data can be used at founding purge time watch according to use frequency of the space. Such, the room that uses everyday (like the bathroom) can get more frequent, more complete cleanness, and the space that uses scarcely can reduce clean frequency (if ask for leave the office of employee) .

Take up sensor can be carried out in build and transforming a project, add the intelligent function such as automation with opening air conditioning system to illume gentle.

People may think only new construction project ability becomes intelligence to build, but the fact is not such. Take up sensor is carried out easily in build and transforming a project, add the intelligent function such as automation with Xiang Zhaoming and HVAC system. This is a good news, because transform existing structure,than demolish and changing the building provides cost effectiveness more and can last.

Take up the type of sensor: Different take up the working principle of sensor

There are a variety of different kinds on the market take up sensor, the type of specific choice depends on the end that we mean to come true.

Passive and infra-red (PIR) sensor

This is the commonnest take up sensor type, the reason is its detect the simple sex of existence and faceless (and safe) method. It is a kind " passive " sensor, through detecting warm object (like person or animal) when to enter its examination to come monitoring space takes up circumstance. These sensor still can be used at generating faceless heat to pursue. Nevertheless, when PIR sensor is held back by the fraise such as vitreous wall, they will not work.

Ultrasonic sensor

These " active " (is not passive) sensor can give out the mankind and animal unheard high frequency sound, and they have a microphone will detect echo. Arrive at the time that microphone place needs according to reflexing sound, sensor can be judged whether somebody is in its " eye shot " in mobile. Ultrasonic sensor can cover larger area than PIR sensor, but they are more sensitive also, accordingly their classics regular meeting is sparked erroneously by the element such as wind or ventilated change.

Microwave sensor

Microwave sensor has a few advantages than PIR sensor: They can detect consistently below all temperature motion, and cover range be 360 degrees (and PIR sensor enclothes limits to be 90 degrees normally) . However, because they can cross wall to feel motion, they may be too accordingly sensitive, cannot accurate in lesser interior space use. Microwave sensor works through transmitting microwave signal (but need not worry, they are complete safety) , accordingly they are considered as " active " sensor. The time that they return sensor place to need through measuring signal to reflex (call echo time) will feel motion. The working pattern of this and ultrasonic sensor is similar, but microwave sensor does not use sound wave, use electromagnetic wave however.

Other sensor

Acoustic sensor is the sensor of another kind of type, but they often are not used, because they also allow easy false triggering. They pass surveillant sound (for example clavier is inputted) will detect the personnel in the space, but they can be disturbed by background noise normally, for example the ambulance is outside the building travel. A few sensor are " mix " sensor, this means what they use a variety of types to detect technology. This kind of sensor relies on great majority of at least two kinds of types detect will decide whether the space is taken up, but they need those who affirm a kind of type to detect only can carry the lamp " open " .

The choice is wired wireless still take up sensor

Sensor also can be wired or wireless. Wired sensor is thought to compare wireless sensor faster, more reliable, because wired sensor does not suffer the effect of distance or wireless interference. This conduces to the rate that raises data to collect and consistency. However, they are costlier also and installation is complex. The cost of wired sensor may rise, specific depend on receive its architecture system repeatedly (be like illume or warm an air conditioning) requires electrical wiring amount. In addition, the cost in inviting eligible professional to receive them the building repeatedly is potential also very tall.

On the other hand, the batteries of wireless sensor needs to change regularly, but the progress of wireless equipment technology makes the battery life of most sensor achieves 10 years of above. The main good point of wireless sensor is installation cost is very low, installation resembles coming off and stickup euqally simple on wall or ceiling, undertake long-range process designing to sensor next, its and illume or HVAC system in group.

Take up the application of sensor: Save the sources of energy and improve productivity

Take up the induction can save the sources of energy, but in commercial structure installation takes up sensor still has a lot of other benefit. Our society is casting off the influence of craze, people begins to return the office, so now is moment the physical space that understands us better is how use. Take up sensor can pass the data that collects building, room and desk utilization rate to help us accomplish this. Can analyse these data to wait in order to form the watch of intelligent purge time, office position that fits productivity.

Apply one: Energy-saving

In a research 2011, lab of Home Ke Liguo released American fatigue Lun Sibai to build illume to control energy-saving assemble to analyse to commerce, discovery takes up the induction can save the sources of energy of about 24% in illume application. The specific power consumption that takes up sensor still conduces to the illume in maintaining commerce to build and HVAC system accords with code of the sources of energy; "When most commerce builds code of the sources of energy to ask to be not being used, be shut or reduce illume " . Take up the response can save the sources of energy through a few kinds of different methods; Include to pass demand pilot ventilated with illume.

? Demand control is ventilated (DCV)By take up sensor supports. According to the space medium the largest living number decides the dimensions of HVAC system, but its had be notted achieve between high above in the sky most when high capacity, do not need this kind of the greatest performance, this is the ground of the use force of DCV. Take up through using sensor and number statistic sensor, can collect the real time data that uses a case about the space, make HVAC system automation, make its are being offerred only proper and ventilated the job below the condition that requires with ideal temperature place.

Indoor environment quality (it is better that IEQ) sensor makes DCV becomes, it can collect the data of the temperature related the indoor environment with the space and air quality and other parameter. For example, in close the large party that holds inside the space may become very warm. If use IEQ sensor to feel,measure temperature, criterion this data can be used at enhancing a space automatically inside ventilated with air conditioning, make its restore ideal temperature. This how with take up sensor cooperates to use? Can take up through automation system basis the circumstance undertakes HVAC is controlled, the member that with be in the space mies wife relatively a long time increases ventilated with air conditioning, vice versa.

In fact, what take up through the basis the circumstance adjusts a structure actually is ventilated, can decrease every year 10% to the energy cost of 40% . Principle of job of demand control illuminative is same; When the space is taken up, illume can be opened automatically, should detect no longer in the space when somebody, illume can be shut automatically.

Because take up sensor can save the sources of energy, apply actually can carry for LEED attestation add cent, and can obtain more integral through DCV.

Take up sensor can raise illume gentle to connect the efficiency of air conditioning system not only, still can help the work efficiency that improves people. Make us thorough be discussed next.

Apply 2: Improve habitant, tenement or staff experience

So far, we had introduced to take up how sensor is used at detecting when and control illume and ventilated. Next administrative levels is to use their data to collect a function to make the person of the space that take up is benefited.

Imagine: The employee of the enterprise begins to return the office after craze, employer already ready-made, distributinged in whole floor of a few faceless, safety take up sensor, the hope understands people how to use the office intuitionisticly. Pass such doing, OK and corresponding ground adjusts the office and assembly room, adjust desk and conference more comfortable to employee position. We know, people is more comfortable, the interference that they get is less, their work efficiency can rise. So, is this how run?

PIR takes up sensor can collect faceless, safe data, send its digital twin (construction manager can be examined take up visibly data, trend, even the potential and feasible view that artificial intelligence technology makes. Next, the position that these information can use at optimizing a building) space in order to improve productivity, provide the data of real time usability of assembly room and desk.

Pass usability data, employee can understand what room, desk to wait to already took up with leisure, use in order to go to the lavatory. Use this kind to take up data can improve conference experience to people works in the space or live, still can help those who spot a structure what part is uncomfortable, and can pass DCV undertake optimizing quality of condition of core of room of overall improvement.

Apply 3: Optimized cleanness plans

Most building is expressed according to consistent date or time set purge time. These clean plans are very simple, but efficiency is normally low. Purge time watch is a basis the building is the busiest day in a year normally (namely the building needs clean time most) will make. According to this schedule, when cleaner everyday or when weekly cleanness, they will be clean every room, resembling this is the busiest in a year a day same.

Dynamic and clean plan resembles pressing require pilot ventilated or illume, but with Yu Qingjie. Use take up sensor, people can make the clean plan of the building according to whether needing clean and specific room or floor. For example, the bathroom is room of generous of stream of people, maintain very hard sometimes sanitation and primitive. If those who use faceless, security is in in the bathroom,take up sensor, the data of the busiest time in can collecting concerned bathroom one day, can arrange clean job directly after this time. Using such dynamic schedule is the more effective method that maintain bathroom cleanness and reduces resident to complain to the greastest extent.

Use take up data

If think to take up sensor can make administrative building is benefited really, needing main main issue so is, The primitive data that can not handle opinion is no-good to most person. Take up sensor suits to collect data very much, but besides, people still needs a kind of method to come monitoring data, examine visible trend (wait for a form in order to heat up graph, chart) , obtain exercisable opinion from inside this data. Apply through will taking up sensor receives the cloud repeatedly (best as compositive as digital twin) , data can transmit applied process through wireless and meshy network, use the software on applied process to have analysis and explanation next.

Cloud application can undertake an analysis, it is to show compositive software can examine sensor data the dependency between the dot, causal with the trend, can make exercisable view according to these trends. For example, if decide the person flow of assembly room is very large (the likelihood has 10 people or more person, specific depend on how is software defined " person flow is large " ) , apply a program to be able to inform an user the room needs cleanness, or the day with the busiest when generating dynamic cleanness to plan account and time.

Take up through using sensor comes the use circumstance of real knowledge space, can raise the sources of energy to use thereby, office layout and the efficiency that cleanness plans. For example, when clean plan becomes more efficient, can use effectively defend the time with clean personnel. Dynamic cleanness plans to still will make habitant more comfortable, and press need pilot illume gentle to connect air conditioning system to be able to save the sources of energy.
