Described central processor CPU can be gathered the data of analog quantity input module AI and carry out computing, and operation result to wireless communication module DTU transmission, is transferred to display module OLED simultaneously; Collection is transmitted the limit switch amount status data of returning and is transferred to wireless communication module DTU by switching value input/output module (DI/DO); Reception transfers to switching value input/output module (DI/DO) by the control command of wireless communication module DTU transmission with correct control command; Receive the instruction that DTU transmits, reset server ip address, information such as sampling interval; The photographing instruction that reception is sent by wireless communication module DTU transfers to image capture module CCD with instruction; Reception is by image capture module CCD image transmitted data, and will be sent to wireless communication module DTU after the data compression;

As preferably, CPU adopts Industry Control level micro power-consumption single-chip microcomputer.This single-chip microcomputer has excellent adaptability to site environment, and it is highly stable and reliable to work, and can satisfy the demand of indoor and outdoor wide region operational environment;

Described wireless communication module DTU, instant and service end connects after receiving the data of being come by CPU transmission, with the data penetration transmission received to service specified end (can set the IP address); Wireless communication module DTU is passed to CPU when receiving the instruction that will receive immediately after the note instruction that is transmitted by service end;

Described display module OLED can show the data that collect, and shows with energy saver mode;

Described image capture module CCD, but acquisition of image data;

Described analog quantity input interface AI designs 8 road interfaces, link to each other with transducers such as temperature, humidity, wind speed, after the pick-up transducers data by information such as number bus transmission temperature and humidities to central processing unit;

Select monobus (1 wire) number bus for use as the digit preference bus, it has, and circuit is simple, and hardware spending is few, and is with low cost, is convenient to advantages such as bus expansion and maintenance; That single unit system has is simple in structure, with low cost, use popular characteristics;

Described switching value input/output module (DI/DO): design 8 tunnel input DI, be used for transmission terminal switching value status data; 8 tunnel output DO can control all kinds of electromechanical equipments such as motor, valve, electric light;

Described power module is for terminal equipment provides power supply.

The beneficial effect of this product is: the CPU of terminal adopts the Industry Control level micro power-consumption single-chip microcomputer of advanced technology, and site environment is had excellent adaptability, and it is highly stable and reliable to work, and can satisfy the demand of indoor and outdoor wide region operational environment.Because power consumption is very low, energy-conserving and environment-protective also can be satisfied the system that in the future upgrades to lithium battery power supply; Monobus (1 wire) number bus, it is simple to have a circuit, and hardware spending is few, and is with low cost, is convenient to advantages such as bus expansion and maintenance; That single unit system has is simple in structure, with low cost, use popular characteristics.

The utility model also can be used for other field application such as unattended machine room except that the remote monitoring that can be used for warmhouse booth.
