QUESTION
Question 1. The design of the model on the principle of action is similar to smart clothesline on Youtube. Then I just said, my equipment has the advantages prominent than intelligent clothesline.
+ model smart clothesline which we refer on Youtube also be controlled automatically by 2 sensors Optical rainwater and return. When it rains, clothing moved into dry. However the sun back then not be pulled out clothes drying automatically by pressing the control button.
+ model we controlled fully automatic
Verse 2. Installation of this equipment in the proper position consolidation, the safest? Specify 2 sensor placement? A device can be simultaneously control many curtains or not?
+ Students we were always conscious protection of school facilities, however this unit is to ensure safety, we should put it in locations less affected most people, such as the ceiling.
+ sensor should be placed in high positions and direction of sunlight, rain sensor located on the doorframe
+ An additional devices on request we can use to control the installation at the same time a lot of blinds. in the suites is affected by several factors such as sun and rain, we only need to use one rain sensor and optical sensor 1
verse 3. So when problems occur such as a power outage, the device can operate is not ? Indicate forward.
+ When a problem occurs, such as a power outage, we can install 1 hand crank to pull the curtain.
Verse 4. Equipment should be provided continuous power, resulting in power consumption big sale, pay electric. So this may conflict with the above advantages, or not?
+ Because the electronic components power consumption is very low, but continuous use but very low power consumption.
Verse 5. Lay presentation why choose topics
Where we go back to the southeast, the entire door is made of wood frame glasses. Morning and afternoon sun splashing into the room making it difficult for our school children. When it rains, the rain turned into a can to affect durability of wood. These natural phenomena have a large effect on the coming infrastructure of schools as well as to the education of our children. Before this reality, we were thinking how to create a system Roll rain curtain, sunshade automatically without the direct control of the people. Contact the knowledge learned in the physics program 9 of automatic control relay, the knowledge to read on the Internet about control automatic lighting system for night and intelligent clothesline can Self collect clothes when it rains, the team we've put the issue is how to combine the contents of this knowledge to design an automatic device with functions:
+ When the rain or sunshine factor affecting the door Lane classrooms and students sitting in the classroom, the system self-shade down.
+ When conditions outside normal or rainy or sunny, but not affect the classroom, the self-collection system curtain back.
So we came up with the idea of creating "Marquises, rain cover in classrooms is controlled automatically by the electronic sensors" to solve the problems mentioned above.
Question 6. I just mentioned properties New, innovative research project compared himself to other projects similar
equipment shall be fully automatic control by optical sensors and sensor rainwater
Question 7. Presentation of the structure and operation of the Products
+ Components: including rainwater sensors, photoelectric sensors, electromagnetic relays, switches itinerary, the electric motor.
The equipment operates under three circumstances:
* / TH1: When there is no rain, no sunny impact on sensor
elements weathered When not acting on the sensor or the intensity has not reached the required level, the engine operation to pull the curtain all the way down. Then switch on the affected journey as switches, motor stopped.
* / TH2: When the rain sensor impact on rainwater
When rain water acting on the sensor, rain sensor that relays the water rain will operate, affecting the motor relays as engine operation shade down. When the curtain has dropped all the way down to the switch at the same time under the affected journey that interrupts the circuit and motor stopped.
* / TH3: When the sun with appropriate intensity effects on optical sensors
As light Light effects on optical sensor, while the optical sensor relay operation to relay the impact of motor engines do pull the curtain down operations. When the curtain was pulled down all switches simultaneously with the journey as affected as electricity and motor circuit breaker shut.
Sentence 8. Why did you choose to mount the electromagnetic relay system without selecting other relays
+ There are many kinds of roles but we use electricity from the role because of the physical program 9 we have learned to understand the structure and use its principles.
Verse 9. I have identified the potential risks What could happen and proposed safety measures is what?
The risks that we were thinking of are:
+ The engine is operating, the power outage, we will mount a crank to pull the curtain up
+ When the engine is running but Belts were a problem, the engine will operate continuously until burnt. We will overcome by getting the role of time.
+ When wind intensity magnitude large enough to damage the system. We need to install additional wind parts. When the wind is strong enough intensity, will affect as closed circuit switches, motor operation to pull the curtain up.
Question 10. Lay outlining data collection process and content proposed research Experience
+ While studying physics program 9, we have learned about the role and motive power from DC
+ sensors, we've been reading on the Internet
Verse 11. Your product has advantages and What's the downside? How can overcome these disadvantages
- Advantages
+ integration of sensor functions rainwater and optical sensors in the same system.
+ The system is controlled automatically, without need direct control from humans.
+ reasonable price products, circuit stability, can widely.
- Disadvantages
+ If stuck halfway lead to engine fires
+ High Voltage, sudden surge currents, fire engine
+ operating system when the power supply
- Remedy
+ Option relays matching voltage, current and power actually needed in practice.
+ Assemble more assembly manual systems (crank) to prevent the unintended incidents occur.
+ Installing Relays time to redress the engine fire.
