Jinan, China Merchants headquarters intelligent home

 Smart home implementations A, wired this way all control signals must be connected by cable, controller end of the signal line is a little more scary, but encountered a troubleshooter is also very difficult. Wired very prominent drawback, wiring complicated, heavy workload, the high cost and difficult to maintain, easy networking. These shortcomings eventually led wired intelligent home only at the concept and pilot phase, it can not be large-scale promotion. So be sure that the smart home to scale and popularize the use of wireless technology is bound to have a market. B, wirelessly currently in the country to see the smart home wireless technologies are: RF 315M and 433M, X-10, z-wave, zigbee, smartroom like. 1, RF, 315M / 433M / 868M / 915M, these radio frequency technology widely used in vehicle monitoring, remote control, telemetry, small wireless networks, industrial data acquisition systems, wireless tags, identification, contactless RF and other places, there are vendors Its introduction of smart home system, but because of its weak anti-jamming capability, networking inconvenience, reliability in general, application results in unsatisfactory in the smart home, good to Chen Pan, and ultimately abandoned mainstream manufacturers, no success stories. 2, power line carrier: x-10 is a control signal a power line carrier (plc) agreement spread through the existing power line communication, China's power grid fluctuations, access to dry more noise and no good Pseudo system, long-distance transmission cause signal weak, bad or slight leakage can cause signal degradation, the most important is that some appliances have the ability to absorb X-10 signal, large screen TV, computer search can be called the X-10 signal killer, which have led to X-10 in the country to promote it difficult, 3, z-wave: supports a mesh topology patterns, home automation applications as the goal, supports up to 232 nodes, a single source chip, only SigmaDesigns a supplier, limited business adoption, not scale, weak stamina will be like Symbian phone system has become as dust swept into history. 4, Zigbee: use the 2.4GHz frequency band, can be run on 2.4GHz, 915MHz and 868MHz lower frequency, etc., supports three topologies shape, mesh, star (Star), the tree can support more than 65,000 nodes, wide range of applications. Zigbee smart home has a two-way communication, free routing, mobile and flexible, and easy to expand and so, no professional installation, users can control their own home on their own combination of installation instructions, to experience the fun of homemade. Automatic networking, to achieve a smooth upgrade, it can add unlimited smart devices, plug and play, quick and easy. Also Zigbee chip and module supplier of many, and because of the relationship between competition, barriers to entry are getting lower and lower, completely open applications, it has attracted many companies to adopt things. All these will make the industry understand the zigbee smart home is to achieve the best wireless communications technology. 5, SmartRoom: the technology is Nanjing IOT Sensor Technology Co., Ltd., set hundreds of technical personnel took decades to zigbee modeled combines the advantages of including WiFi, RF, Bluetooth and other wireless technologies, breaking the many limitations ZigBee Technology while fully downward compatible ZigBee, a communication protocol is a completely Chinese people themselves intellectual property rights, let us go out in the field to get the outside of things to say "no" to the right. The whole point of wisdom home infrared repeater _CNPB_I020, using ZigBee / SmartRoom technology, comprehensive multi-angle design, the ZigBee / SmartRoom radio signals and infrared wireless signal is more closely associated with them, to control the TV, air conditioning, electric curtains mobile intelligent terminals using an infrared remote control device. In addition to the wisdom of the home, this product because of their high intelligence, widely used in smart hotels, wisdom hospitals, intelligent buildings and other places. 1, support ZigBee / SmartRoom agreement; 2, installation is simple, convenient manipulation; please call for inquiry 15,58,88,52,061 3, intelligent design, signal transmission more stable and reliable. Communication IEEE802.15.4 (ZigBee / SmartRoom) communication distance 100m (under visual conditions) Power Requirements 110 ~ 240V Operating temperature -10 ℃ ~ + 55 ℃ Jinan smart home company China Merchants headquarters
