Compared with traditional household, Internet of Things household is except can realizing the basic function of traditional household, people can also be realized be connected with thing with thing, thing, achieve the control and management network of intelligent information, and have the advantage of energy-conserving and environment-protective concurrently, it is farthest efficient, convenient for, comfortable safety to bring.
2014, Chinese energy consumption still occupied first place in the world, and accounted for 21.5% of total worldwide energy consumption; China's energy relative shortage simultaneously, energy dissipation is very serious again.There is the problems such as safety coefficient is low, volume is comparatively large, electric conversion efficiency is low, backward in technique, Consumer's Experience is poor, energy-conserving and environment-protective performance is poor in the common equipment in current household heating market.
PTC electric heater can have the features such as length natural life-span, automatic constant-temperature, the flames of anger, high reliability, energy-saving effect be remarkable due to PTC element, solves the problem well.Its automatic constant-temperature effect shows: when PTC heater element is energized, temperature is lower, and now resistance is little, and power is very large, and can heat rapidly, when temperature rises near Curie temperature gradually, resistance sharply increases 3 ~ 7 orders of magnitude (10
3~ 10
7doubly).Now under constant voltage effect, reduced by the electric current of element, respective element temperature is in equilibrium state, when PTC temperature of heating elements reduces for a certain reason, its resistance value reduces, and then the electric current resulting through thermistor element increases, component temperature raises, and makes temperature reach equilibrium state again.By repeating said process, PTC heater element itself can regulation output power automatically, thus reach temperature automatically controlled object.
Summary of the invention
Invent a kind of PTC intelligent heating system based on technology of Internet of things, solve the problems of existing household heating equipment, there is easy and simple to handle, automatic adjustment, durability be strong, safe and reliable, quiet, volume is little, the advantage such as energy-conserving and environment-protective, user can realize the object of home intelligent heating whenever and wherever possible by native system, can economize energy safely and reliably.
This PTC intelligent heating system based on technology of Internet of things, is characterized in that this system comprises CPU module, control circuit module, PTC heating module (PTC electric heater), wireless communication module, family wireless network, Internet network, smart machine, intelligent software client.Wherein central authorities' process processor module is connected with wireless communication module with control circuit module respectively; Control circuit module is connected with PTC heating module and working power thereof, with the duty of control PTC heating module; Wireless communication module is connected with described household wireless LAN; Household wireless LAN is connected with Internet network; Smart machine is connected to Internet network by Wi-Fi technology or 2G/3G/4G technical battery, and described intelligent software client is arranged on smart machine.
Described PTC intelligent heating equipment can have and is one or morely linked into family lan simultaneously, and user can control one or more PTC intelligent heating equipment simultaneously.
Described control circuit module is for the duty of control PTC heating module.
Described wireless communication module is connected with family lan by Wi-Fi, realizes the secure connection of INTELLIGENT PTC heating equipment and family lan within the specific limits.
Described smart machine can be smart mobile phone, Intelligent flat computer or other smart machines that can surf the Net; And install intelligent software client carry out operation use.
Compared with prior art, outstanding advantages of the present utility model is, the INTELLIGENT PTC heating system based on Internet of Things of invention, enable user controls in family room whenever and wherever possible heating equipment when having and network can being used to connect, due to advantages such as self is easy and simple to handle, durability strong, automatic adjustment, safe and reliable, quiet, volume is little, energy-conserving and environment-protective, under native system can be widely used in various complex environment.The realization of above function, conscientiously for user constructs comfortable, convenient, efficient, a safe wired home heating system.
