Description
Technical Field
The invention relates to the technical field of power sockets, in particular to an intelligent socket.
Background
Since the eighties of the twentieth century, the incidence of electrical fire in China has been high, and huge losses are caused to national economy and people's life. The data show that over 80% of electrical fires occur at a higher than safe voltage or current than that required by the circuit breakers in the electrical outlets. The traditional power socket does not have the function of automatically detecting the electric energy parameters, and the power socket cannot automatically cut off the power supply because the voltage and the current which can be provided by the power socket are not enough to meet the requirements of the current electrical equipment. The electric energy parameters such as voltage, current and the like of the current electric equipment in the working state can not exceed the maximum voltage and current values which can be provided by the power socket so as to carry out early warning treatment, and the electric energy parameters can be reported to power users in time so as to prevent the occurrence of electric fire accidents.
Meanwhile, in China, thousands of children touch the power socket every year to cause electric shock or burn accidents. The reason for this is mainly because the conventional power socket has power supplied to its jacks regardless of whether the electrical equipment is connected to the power socket. Aiming at the defects and the defects of the traditional power socket in function, the intelligent power socket with the protection function is urgently needed by most of power users. Patent CN104917002B "intelligent power socket based on thing networking" adopts RFID radio frequency identification technology to realize detecting whether there is electrical equipment to insert, just gives the socket power supply when electrical equipment inserts the socket, but this kind of scheme requires RFID identification circuit to work always, and stand-by power consumption is great, and because RFID identification circuit and control circuit work for a long time, leads to the life-span of product to shorten.
The fire caused by the existing socket usually has the following reasons:
1. the lead and the electrode on the socket are not tightly fixed, poor contact is caused, and heat is generated;
2. the overload uses a high-power electric appliance, exceeds the allowable current of a socket and causes heating;
3. the socket is soaked or damped, the insulation is reduced, electric leakage and even short circuit are caused, and fire is caused;
4. the socket itself is of poor quality, internal damage, causing short circuits, etc.
The conventional power socket in the market only has a simple overheat protection function, and the temperature sensor has a single temperature measurement mode (cannot well measure the temperature of all reeds of the power socket) or is irreversible due to overheat deformation (or fusing), or has an unadjustable temperature overheat protection threshold value, and is single in function and cannot well meet the actual requirement.
Therefore, by adopting the intelligent power socket, not only can the lives of thousands of people be saved, but also the people can be prevented from being injured by fire for thousands of times, and in addition, huge property loss can be avoided. The intelligent power socket can be widely applied to various fields such as families, offices, factories and the like. Worldwide, hundreds of millions of such smart power outlets are required. Therefore, the intelligent power socket has huge market application prospect and social demand.
