A kind of intelligence socket, comprises with the front panel for electric jack, the housing with power supply pedestal and rly.; Described intelligence socket also comprises: comprise one-chip computer module, GPRS communicates module, current and voltage signals gathering device and overheat protector module; Described one-chip computer module is by micro-chip chip, clock chip and DC voltage-stabilizing electric power generating composition; Described overheat protector module comprises hummer and temperature sensor.

Described intelligence socket, the input and output circuit of common socket 220v part is received rly., and then by mobile phone sending signal, GPRS communication module Received signal strength also passes to micro-chip, sending high lower level after micro-chip processing signals, relay break-make realizes the remote on/off to electrical appliance. Temperature sensor is arranged on rly., and when rly. surface temperature is more than 60 degrees Celsius, micro-chip output signal disconnects rly. and starts hummer alarm, it is achieved to the overheat protector of circuit. Voltage and current signal gathering device is connected to and exports on electric wire, and real time data is sent on micro-chip to be sent to mobile phone terminal via GPRS communication module again realize detection, and during over-voltage and over-current, micro-chip control rly. disconnects.

The beneficial effects of the utility model are: energy consumption is low, it is possible to the problem that the point of contact temperature effectively preventing socket from causing because of loose contact is too high. There is long-distance remote control simultaneously, the function of monitoring electrical appliance. Greatly facilitate transformation and the upgrading of intelligence household house, improve the quality of the life of people.

Embodiment

Below in conjunction with specific embodiment the utility model is further explained explanation.

In figure: 1-housing, 2-front panel, 3-jack, 4-one-chip computer module, 5-current and voltage signals gathering device, 6-overheat protector module, 7-GPRS communicates module.

As shown in the figure, a kind of intelligence socket, comprises with the front panel 2 for electric jack 3, the housing 1 with power supply pedestal and rly.; Also comprise: comprise one-chip computer module 4, GPRS communicates module 7, current and voltage signals gathering device 5 and overheat protector module 6; Wherein one-chip computer module 4 is by micro-chip chip, clock chip and DC voltage-stabilizing electric power generating composition; Overheat protector module 6 comprises hummer and temperature sensor.

Select PIC16F877A single-chip minimum system plate, battery-powered. The fast volume low in energy consumption of PIC16F887A travelling speed is little; RB4RB7 port has saltus step and interrupts function, conveniently receives keyboard input signal; There are 10 multi-channel a/d converters; Separately can enter dormancy pattern, reduce power consumption. RA0 and RA1 is respectively as socket voltage and electric current signal A/D input terminus, RB0 is as the input terminus of temperature signal, RB4RB7 receives keyboard input when being used for test in advance, RC0RC2 is used for and the communicating of clock chip DS1302, RC3 is used for the switching over of relay, and RC7 is for controlling hummer.

Digital temperature sensor DS18B20 is selected in the collection of temperature signal, and it has three pin TO-92 small volume packing forms, and temperature measurement range is (-55 ,+125), is programmed for 9-12 position A/D conversion accuracy, surveys temperature resolving power and can reach 0.0625. Due to DS18B20 only 1 serial communication interface, very simple with the junction circuit of micro-chip, only need the RB0I/O port with micro-chip to connect, for read-write and temperature transition can obtain energy from data line itself.

Rly. is the switch utilizing magnet control pull up circuit break-make, here 5V rly. HRS4-S-DV5V is adopted, driving electric current is 70mA, the maximum changeable electric current of normal-closed end can reach 10A because of rly. electric current and be greater than PIC single chip microcomputer I/O maximum drive current (25mA), the triode 8050 of NPN is accessed at RC3 output terminal, strengthen its driving force, IN termination micro-chip RC3, DC+ DC-connect power supply.
