Recently, ubiquitous (Ubiquitous), which provides information and communication that allows users to freely connect to a network regardless of a network or a computer, has been put into practical use. When such ubiquitous becomes popular, information technology can be utilized not only in the home but also in the outside and remote areas. However, in order to achieve ubiquitous network, advancement of information technology such as generalization of broadband communication and convergence technology, and low price of information technology equipment should be premised. Ubiquitous is not yet common due to these limitations, but there is a global development competition not only because of portability and convenience, but also because of the advantages of accessing the network regardless of time and place.

With this ubiquitous, the Zigbee standard is slowly emerging as the next generation of near field communication to replace Bluetooth. ZigBee is a technology suitable for the ultra-small, low-power, low-cost market that requires simple functions. It is estimated that ZigBee can replace power line communication, which has been delayed by standard, and Bluetooth, which is becoming less commercialized. It is applied to the field.

ZigBee is one of the IEEE 802.15.4 standards supporting near field communication. It is a technology for near field communication and ubiquitous computing within 10m ~ 1km in wireless networking field such as home and office. Data can be transmitted at a speed of 250Kbps within a radius of 1km. With this mesh network structure, about 255 devices can be connected to one wireless network. In addition, it is economical and easy to manage because it can be used for several months to two years with only two AA alkaline batteries used in real life. Unlike other wireless communication technologies, ZigBee has low power consumption and low-cost products, which can be applied to various ubiquitous environments such as intelligent home network, building and industrial device automation, logistics, environmental monitoring, human interface, telematics, and military.

In particular, ZigBee is considered suitable for simple wireless control such as lighting control, heating control and gas valve shut-off in home networking.

The home automation using the Zigbee communication module is to remotely control the home appliances in the home to develop and commercialize repeatedly. In the early stages of home automation, each device was controlled separately using a telephone or an infrared ray, and no connection was made between each device, but now, a communication network is used to establish a network between home appliances and control the network. We are using a method that allows integrated management.

In addition, a newly built apartment or house can adopt a home network system to enjoy a convenient and safe life. In particular, by establishing a heating system to control the heating temperature in each room required time, it is possible to save 25-30% of the heating cost compared to the existing heating system. However, in an apartment apartment or a house, a separate power line or communication line must be installed in order to construct a home network, but it has a limitation in constructing a home network because of the high cost and difficulty in construction.

As described above, there is a need to develop an access point and a wireless repeater using a Zigbee method suitable for a ubiquitous environment, and to develop a Zigbee type wireless data communication system constructed by them.

The present invention has been invented to solve the above-mentioned requirements, the object of the present invention is to detect the presence of residents in the room, temperature and humidity, detect the presence of fire, determine the presence of residents in the room, and detect the detection signal Intelligent integrated heating and heating switch using the ZigBee wireless communication method that can intelligently determine the temperature of lighting and heating, control gas circuit breakers, fans, humidifiers and home appliances, and provide comprehensive services in connection with existing home network systems. Its purpose is to. Also, it is a product that can be installed immediately after removing the existing switch box, and it is designed to supply the power of the switch circuit stably with the power line leakage current of the switch 1 line when the power is turned off without using a complicated battery. There is this.
