Problems solved by technology

[0004] Although this scheme can achieve the purpose of safe use under certain conditions, there are still potential safety hazards in the field of use with high requirements
For example, in outdoor applications, leakage and short circuit problems often occur
[0005] In addition, the existing safety power socket only considers the potential safety hazard caused by the human body touching the socket socket, and does not consider the safety problem caused by the problem of the electrical appliance
At present, the way to deal with this problem is to protect it through the fuse in the socket. The overload current of the fuse is much greater than the load itself. When the load equipment has a large current overshoot, the insurance will work. damaged

Abstract

The invention relates to a high safety intelligent power socket. A control switch is connected between the AC input voltage and the plug electrodes of the socket. The control switch is used for controlling the AC input voltage to be outputted to the plug electrodes of the socket to empower the voltage. The I / O interfaces of a microprocessor are electrically connected with the control interfaces of the control switch. The microprocessor controls the control switch through the interface control. The microprocessor test the output signals in-place state test unit through input interfaces, the in-place state test unit comprises a micro range detection unit, a human proximity detection unit, and an occlusion detection unit. Not only a safety test stage is added to the in-place state test unit, but also an overload detecting unit, a leakage detecting unit, a wireless network unit are added to the in-place state test unit to fully guarantee the safety of touching the electrodes by people. The electrical appliances can be protected when accidents occur, besides a wireless network unit is added in the intelligent power socket to make the electrical appliances smart.

Description

technical field [0001] The invention relates to a power socket, in particular to an intelligent power socket with high safety. Background technique [0002] Chinese patent discloses a kind of safety power socket, it designs a photoresistor and light-emitting tube under the corresponding power plug, when the power plug is inserted into the corresponding hole of the socket, the resistance of the photoresistor increases, and the external power supply (such as AC 220V or AC 110V) is electrically connected to the plug to power the device. However, when the electrodes in the power socket are directly touched by human hands or the electrodes in the power socket are touched by metal, the opening of the photoresistor cannot be completely covered, and the value of the photoresistor is low. The power is disconnected to achieve the purpose of safe use. [0003] When the light is dark, in order to achieve the purpose of safety, a light-emitting device is installed on the side of the ph...
