P2C technology: a milestone in the opening, interconnection and civilianization of smart homes
What is P2C technology? P2C technology, also known as power pulse communication and control technology, is a new type of non-carrier power line communication technology. It uses AC power supply line as the communication transmission carrier, and uses the half-wave pulse of AC as the signal source of communication. The on-time of the half-wave pulse is controlled according to a specific coding mode, thereby realizing the transmission of data information. Simply put, the combination of the traditional thyristor dimming pulse pulses at different brightness levels is used as the basic signal for information transmission, and is directly supplied to the power device that can decode the pulse combination through the power line. At the same time as the power is supplied, control information is also transmitted. 220VAC AC half-wave conduction angle clipping pulse signal P2C technology is a low-speed, short-data, high-reliability and low-cost communication technology. It is suitable for power supply switches, simple adjustment and basic control of lighting and home appliances. It has low communication transmission speed and bandwidth requirements, and achieves reliability and reliability. Real-time requirements require high control and connectivity. Compared with the long-established power carrier communication technology, P2C technology has higher reliability, longer transmission distance, lower product cost and simpler application development. Compared with various wireless connection technologies that are currently widely used, P2C technology has obvious advantages of no barrier to the partition wall, no high-frequency radiation, and large signal and high anti-interference. P2C technology is part of the China Smart Home Industry Alliance (CSHIA) Control Free program and is the first hardware open source interoperability technology standard. P2C technology has complete Chinese independent intellectual property rights, and its core patent technology is shared freely by alliance members. It is the basic connection technology of smart home industry, especially for the popular application of lighting control, smart lamps, smart small appliances and super switches. Is a key technology with a milestone. The P2C technology was developed and promoted by the China Smart Home Industry Alliance (CSHIA) P2C Working Group. The working group was formally established in Jiaxing University in Zhejiang in July 2015. The sponsors and affiliates include Shenzhen Botu Kangzhuo Intelligent Technology Co., Ltd. and Xiamen. ABB Zhenwei Electrical Equipment Co., Ltd., Zhejiang Zhengtai Electric Co., Ltd., Zhejiang Dahua Technology Co., Ltd., Guangdong Ruide Intelligent Technology Co., Ltd., Shanghai Op Lighting Co., Ltd., Ningbo Duya Electromechanical Co., Ltd., Beijing Tiancheng Xinyu Companies such as Science and Technology Co., Ltd. officially launched the P2C1.0 version of the protocol standard with lighting control as the main body in April 2016. Application characteristics of P2C technology The most prominent application feature of P2C technology is that all intelligent devices fully realize high-reliability and low-cost wiring-free installation, that is, products using P2C technology, such as smart lamps, smart appliances , super switches, etc. Under the premise of any wiring, only need to access the 220VAC mains to automatically achieve interconnection. For example, the wall switch can be directly replaced by the super switch, or the smart lamp can be directly replaced with the original ordinary lamp, or the smart home appliance can be inserted into the 220VAC socket, or the gateway type control device can be directly installed on the distribution box rail, etc. Automatic connection of switch panels, smart lights, smart home appliances and local area networks.
