In 3 embodiment, first signal of telecommunication can be made as to voltage signal or current signal, the second electricity to go forwardSignal correspondence is made as current signal or voltage signal, and so, second signal of telecommunication can adopt the default electricity of softwareStream constant, as 1V or its multiple, or 1A or its multiple, also can be by default auxiliary circuit, from auxiliaryCircuit obtains current signal or voltage signal as second signal of telecommunication; In embodiment 3, non-electrical sensor producesRaw is not the analog electrical energy signals such as direct voltage, electric current or resistance, but frequency signal, so,By software approach, first, by frequency numerical value, convert the non electrical quantity of detection by corresponding reduction formula toSignal---stress signal numerical value, then, adopts the conversion of direct unit, indirect this non-electric charge quantity signalling numerical valueBe converted to voltage value; In embodiment 4, another non-electrical sensor inspection of particular suitable relation will be there isSurvey the non-electric charge quantity signalling coming and be converted to current signal or voltage signal as second signal of telecommunication.
Non-electric charge quantity signalling provided by the invention gathers monitoring method, gathers to be checked by non-electrical sensor is setSurvey non-electric charge quantity signalling, for example temperature data, pressure data, light data, humidity data or pressure data,Then, directly or indirectly convert non-electric charge quantity signalling to electric quantity signal, and produce power signal by processing,Then carry out integration and obtain energy class parameter, thereby non electrical quantity is detected and converts each time period energy class parameter toDetect, be conducive to early stage small-signal in various transient state hidden danger to accumulate amplification, in occurring in hidden dangerEarly stage monitoring is in time found, avoids hidden danger seriously to change, thereby avoids loss, reduces risk.
The above, be only preferably detailed description of the invention of the present invention, but not office of protection scope of the present inventionBe limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in, according to thisThe technical scheme of invention and inventive concept thereof are equal to replaces or changes, and all should be encompassed in protection of the present inventionWithin scope.
