Electronic product solution development smart home management and control solutions
1. Intelligent management and control
Electronic product solution development smart home management method control refers to the housing as a service platform, build both engineering construction, communication network, information appliances, machinery and equipment automation technology, set system software, structure, service items, management methods as one of the high efficiency, comfortable, safe, convenient, environmental protection of the settlement of the natural environment, according to the technology of the Internet of things All kinds of equipment in the home are connected together to show a variety of functions and ways, such as home appliances control, lighting control, curtain cloth control, telephone remote control, indoor and outdoor remote control, anti-theft alarm system, and its programmable controller timing execution control, etc., to help maintain smooth information communication between the home and the outside world, improve everyone's living habits, and assist the family We should arrange our time reasonably to improve the safety factor of our living.
2. Lighting socket control, market products in the program is divided into two kinds
The structure of wired control is that the controller is placed in the strong current box, and the switch and the central control host are controlled through the weak current control line respectively
The advantage is safety and stability
The disadvantages lie in the high requirements of the scheme design, the high requirements of the line erection, and the difficulty of the later expansion and modification.
This way is more used in the early development of smart home, which is transformed from industrial control.
It is mainly suitable for large-scale commercial places with centralized management by special personnel
The structure of wireless control and wireless control is basically the same as the traditional wiring mode of home decoration. The remote control switch directly controls the light, and the central control host transmits the wireless signal to control the working state of the switch.
Advantages: simple installation and wiring, almost no difference compared with the traditional way
Disadvantages: domestic 315 / 433 RF wireless switch, signal coverage and other issues
The indoor distance is 100 meters, the open distance is 2000 meters, if the villa needs to add signal transfer amplification. ZigBee 2.4G wireless products do not have the above problems, but because the core technology relies on imports, we have not successfully developed similar products. The current 2.4G equipment has a short signal transmission distance (generally 10-30 meters, reliable communication distance 10 meters) and the price is the same as other domestic RF switches. The distance is shorter. I will explain in detail in the following product selection section. 2.4G ZigBee is not for civil use, but for industrial technology and low flow WiFi. However, with the large-scale application of WiFi, ZigBee is not only a hyped concept in China, but also less and less used abroad. Note: both ZigBee and WiFi are based on 802.
3. Background music system
Background music system can be roughly divided into two types, one is central background music, the other is split background music
The structure of the central background music is similar to the background music in our unit or business place, that is, a power amplifier host is connected with multiple speakers, except that the professional central background music can be controlled by zones, and each zone will have a weak current panel, which can independently control the playing of different music in the zone.
The advantages are: good sound quality, wide coverage area, easy to control, unified play, also can play in different areas.
The disadvantage is that the circuit is complex and the cost is high, so it is suitable for big houses or customers with higher requirements.
The structure of split background music is equivalent to a number of small central background music units, and each area is independent.
The utility model has the advantages of simple installation structure, low cost, suitable for regional transformation and small house type.
The disadvantage is that the power is limited, the number and power of speakers are limited, and it can't be played uniformly in all areas, but I think it's more suitable for most families.
4. Electric curtains, electric doors and windows, etc
Electric curtains and doors and windows belong to black electrical appliances, that is, electrical equipment that only needs to control the power on and off and polarity. In terms of control, they belong to a relatively simple type. They only need to lay a good power line and leave the installation site of the controller. The wireless signal connection between the central control host and the controller is OK.
5. Security system
Security system, can be divided into two basic blocks, 1, is the monitoring video, 2, anti intrusion alarm.
There are two kinds of structure: wireless and wired.
I personally think that the security system, which is related to safety, has higher requirements than the control system in terms of stability and reliability. Therefore, I recommend the use of wired structure here. In terms of scheme design, I suggest consulting relevant professionals, so I will not elaborate here.
In the connection between security system and intelligent host, many customers will choose the intelligent host with security function. I think this way is improper. In fact, security and central control equipment are two concepts. Security is just a subsystem of intelligent control. As long as it is a standard professional intelligent central control host, it can be connected and controlled, and most of the devices with security function on the market The main engine appears because most manufacturers are engaged in security equipment before, which highlights security and weakens intelligent central control. So I suggest giving priority to the intelligent central control system, and then supporting professional security equipment, because professional security equipment in addition to higher requirements, manufacturers will insure the system, so your family property is equivalent to double insurance, that is, protection before something happens, and compensation after something happens.
So in the global security industry, rf433 and 315 are widely used, so RF is a technology that has been widely used and verified.
6. AV system, generic cabling system
Audio video system is a complex system in the family weak current, and it is also closely related to generic cabling, so I will put them together to explain.
In fact, we have been using the AV system. What are the differences between the wiring of the AV system in smart home and ours?
First of all, video server can be divided into video editing server integrated and video editing server split, commercial level and household level.
In terms of structure, set top box, TV, DVD and computer work independently. In short, the integrated wiring of smart home is to put all the audio-visual equipment together for centralized distribution and management. The benefits are resource sharing, large space for later transformation and expansion, and centralized equipment placement behind the cabinet, which is conducive to fire safety. The TV set is dry and clean, and there is no need to install Set up a TV cabinet to save space. Each TV can switch between set-top box, DVD, computer and monitoring screen by one button. The mode of generic cabling is changed by the above requirements, so I will only explain its characteristics here. If you are interested in purchasing intelligent central control equipment, you can ask the merchant to design the scheme.
