Cascade socket control system based on local area network

Abstract

The invention discloses a cascade socket control system based on a local area network. The cascade socket control system comprises a single-chip microcomputer, a relay module group, a displayer, a power supply module, a safety lock module, a Zigbee communication module and a timer. The single-chip microcomputer is connected with the power supply module, the safety lock module, the timer, the displayer, the relay module group and the Zigbee communication module. The relay module group is connected between 220VAC and the socket. The intelligent socket has the following advantages that 1, the one-to-many problem is solved by the gateway so that one terminal can simultaneously control multiple intelligent sockets; 2, the intelligent socket uses a zigbee low power consumption protocol and uses AES-128 encryption communication without data security risk; 3, the safety lock function is added in the intelligent socket so that the socket power supply can be automatically turned off when the human body approaches and thus people can be protected from the damage of electric shock; and 4, independent timing control can be performed on the socket by using mobile phone side software, and the work time of each switch is set so as to achieve the objective of multi-control.

Description

technical field [0001] The invention relates to an intelligent socket, in particular to a cascaded socket control system based on a local area network. Background technique [0002] ZigBee is a low-power LAN protocol based on the IEEE802.15.4 standard. According to international standards, ZigBee technology is a short-distance, low-power wireless communication technology. This name (also known as Zigbee Protocol) comes from the eight-character dance of bees, because bees (bee) use the "dance" of flying and "buzzing" (zig) to shake their wings to communicate with their companions the location information of pollen. That is to say, bees rely on this method to form a communication network in the group. It is characterized by close range, low complexity, self-organization, low power consumption, and low data rate. It is mainly suitable for the fields of automatic control and remote control, and can be embedded in various devices. In short, ZigBee is a cheap, low-power short-...
