Abstract

The utility model relates to a network playing connector of which the circuit is formed by connecting a microprocessor MCU, a cache memory RAM which can be read and written, and a signal treating circuit, wherein, the microprocessor is connected with the cache memory RAM through a twenty-bit address line, an eight-bit data line, a chip selection line and a reading and writing control line; the output of the signal treating circuit is connected with a network port; the signal treating circuit can comprise 8019 type chips, and can also comprise modulation demodulation chips. The utility model can carry out explanation and packing for signals in the RAM through the TCP/IP protocol packet under the control of the MCU, and can treat the signals in the RAM through the 8019 type chips. Then, the signals in the RAM are connected with an ethernet through an ether mouth. The signals in the RAM can also be connected with the network through telephone lines after converted into acoustic frequency signals through the modulation demodulation device. When the network playing connector is connected, the network playing connector can be used for playing the network. The utility model has the advantages of convenient operation, portability, low cost and strong special performance. When the network playing connector is provided with household furniture or work control software, the utility model can achieve the goals of meter copying on a network or remotely and automatically controlling a household electric apparatus. The utility model is really a modern network product with advanced technology which can realize the automatization management scheme.

Description

Internet link

Technical field

The utility model relates to a kind of device that utilizes the chip microcontroller function of surfing the Net, is specifically related to a kind of Internet link that is used to realize digitlization household automation Managed Solution.

Background technology

In existing login technique, special software systems explanation procotol is arranged, people adopt mostly and directly link the purpose that personal computer reaches online on networks, and the hardware cost of support and operating software system is very high.And a kind of digitlization household automation Managed Solution, realize reading automatically the reading of ammeter, gas meter and water meter and calculate the expense that each resident family should pay, can also control the break-make of appliance switch in the user family and control power supply, coal gas, water and cable TV and reach burglar alarm and purpose that emergency medical is sought help.If use network access in the past, its cost is very high, uses also inconvenience, the Internet device that need a kind ofly conveniently surf the Net, cost is low and specificity is strong.

The utility model content

The utility model provides a kind of Internet link that utilizes the single-chip microcomputer online, and this Internet link can reach the purpose of network meter reading or remote automation control household electric appliances, thereby realizes the household automation Managed Solution.

The utility model provides following technical scheme, a kind of Internet link, its circuit links read-write buffer memory RAM by microprocessor MCU and signal processing circuit is formed, microprocessor is by 20 bit address lines and eight bit data line and chip select line and read-write control line binding buffer memory RAM, the output connected network port of signal processing circuit.

Described signal processing circuit can comprise 8019 chips, there are five bit address lines to connect the address wire of 8019 chips in the 20 bit address lines of microprocessor, the eight bit data line of 8019 chips links the eight bit data line of microprocessor, and 8019 chips also link microprocessor MCU by control line.

Described signal processing circuit can comprise modem chip, and modem chip has data communication line to link microprocessor MCU, and modem chip also links signal transfer circuit.

Owing to adopted above technical scheme, in use if the telephony interface that the network interface of Internet link is received Ethernet interface or the Internet just can surf the Net, operation is carried all very convenient, cost is low, specificity is strong, household or industrial control software are installed in Internet link can be reached just that special-purpose checking meter paid dues or the purpose of remote automation control household electric appliances on the net, real for a kind of technological precedence and can realize the modernized networking products of household automation Managed Solution.
