Abstract
The present invention discloses a contactless intelligent instrument setting method and a device thereof. The contactless intelligent instrument setting method adopts the principle of magnetic induction to control the magnetic switch keyboard of an explosion-proof intelligent instrument in a completely sealed body to complete setting and switching the system. The intelligent instrument is provided with a casing, wherein the rear end of the casing is provided with connecting tubes and is connected with a sensor, the front end of the casing is provided with a panel, explosion-proof panel glass and an instrument cover plate, a display and a magnetic control switch keyboard are arranged on the panel, and a circuit board is arranged in the casing. The present invention has the advantages of simple structure, convenient use, safety, reliability, etc.
Description
The present invention relates to instrument method to set up and device, relate in particular to non-contact type intelligence instrument method to set up and device.
The safety requirements instrument and meter for automation exists various inflammable, explosion hazard gasess in many occasions such as oil, chemical industry, in order to have explosion-proof performance.Along with the increasing instrument of the development of microelectric technique realizes intelligent.The formula smart instrumentation is battery-powered on the spot, can only adopt the flame proof method for explosion-proof.Intelligence instrument function more, its setting, it is very difficult to switch the explosion-proof treatment process of keyboard, general technology is sealed in intelligence instrument in the instrument housing, setting and switch must uncap, not only dangerous but also inconvenient.The purpose of this invention is to provide a kind of non-contact type intelligence instrument method to set up and device simple in structure, esy to use, safe and reliable,
To take following measures non-contact type intelligence instrument method to set up be to adopt magnetic induction principle in the present invention in order to achieve the above object, and flame-proof intelligent instrument magnetic switch keyboard in the complete seal is controlled, and finishes the setting and the switching of system.Its device has instrument housing, the housing rear end is provided with connecting pipe and links to each other with sensor, the housing front end is provided with panel successively, explosion-proof face glass, the instrument cover plate, panel is provided with display, the magnetic switch keyboard is provided with wiring board in the housing, the circuit of said circuit is: sensor produces the charge signal of pulse change, amplify through amplifying circuit, filtering is sent into microprocessor and is calculated, and operation result is delivered to the display demonstration, receives setting and switching from the magnetic switch keyboard, battery-powered, the circuit each several part should be accomplished little power consumption.
Advantage of the present invention be simple in structure, with low cost, set and switch with contactless the finishing of magnet, esy to use, safe and reliable, cooperates the function that can realize each and complexity with microprocessor.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is that non-contact type is provided with the intelligence instrument structural representation;
Fig. 2 is that non-contact type is provided with intelligence instrument surface structure synoptic diagram;
Fig. 3 is that non-contact type is provided with intelligence instrument wiring board circuit block diagram;
Non-contact type intelligence instrument method to set up is to adopt magnetic induction principle, flame-proof intelligent instrument magnetic switch keyboard in the complete seal is controlled, finish the setting and the switching of system, the general magnet that adopts, tongue tube keyboard to flame-proof intelligent instrument in the complete seal is controlled, and finishes the setting and the switching of system.Intelligence instrument is an intelligent thermometer, intelligent manometer, intelligent flow table.Its device has instrument housing, the housing rear end is provided with connecting pipe and links to each other with sensor, the housing front end is provided with panel successively, explosion-proof face glass 4, instrument cover plate 1, panel is provided with display 2, magnetic switch keyboard 3, be provided with wiring board 5 in the housing, the circuit of said circuit is: sensor 6 produces the charge signal of pulse change, amplifies through amplifying circuit 7, filtering is sent into microprocessor 8 and is calculated, and operation result is delivered to display show, receive setting and switching, by battery 9 power supplies from the magnetic switch keyboard.The magnetic switch keyboard is the tongue tube keyboard.Sensor force temperature, pressure, flow sensor.Keyboard F/ ∑ is used to switch various function computings ,+,-being used for setting numeral, S is used for setting item and switches.
