Abstract
The utility model relates to novel multimeter which includes a charging circuit, a super capacitor, a time delay switch, a single-chip microcomputer, a display screen, a sound and light alarm, a memory, an overload value selection module, an operation button, an A/D converter and a measuring probe. The time delay switch, the display, the sound and light alarm, the memory, the overload value selection module, the operation button and the A/D converter are all electrically connected with the single-chip microcomputer. The charging circuit is electrically connected with the time delay switch via the super capacitor. The measuring probe is electrically connected with the single-chip microcomputer via the A/D converter. The novel multimeter can store and display measurement data, and take out the saved data as needed; can send out automatic alarm prompt in overload measurement; and can conduct automatic shutdown to save energy after being idle for more than a set time.
Description
Technical field
The utility model relates to multimeter.
Background technology
Multimeter is widely applied in electric measurement field, and it is also a conventional indispensable instrument and equipment of Electrical Engineering and Its Automation specialty simultaneously.It is a kind of multi-functional, multiple range electronic instrument, can be used for measuring the physical quantitys such as DC current, voltage, alternating current, voltage, resistance.
Traditional multimeter can only read for disposable, this just requires user conscientiously to watch measurement result with eyes, therefore gauger will watch while measuring when measuring, also will record the data of each measurement, as long as gauger diverts one's attention to cause a little, measurement data is forgotten, misregister so simultaneously.When the data measured when needs are more or densely distributed, the accuracy of measurement will be had a greatly reduced quality, and measurement efficiency also will be greatly affected.No matter be in the study experimentation of electric automatization or in staff's execute-in-place process, all to user, bring very large inconvenience.
Utility model content
The purpose of this utility model is to propose a kind of Novel universal table, and it can solve problem that cannot storage of measurement data.
In order to achieve the above object, the technical scheme that the utility model adopts is as follows:
Novel universal table, it comprises charging circuit, super capacitor, delay switch, single-chip microcomputer, display screen, audible-visual annunciator, storer, overload values selection module, operation push-button, A/D converter and measuring sonde, delay switch, display screen, audible-visual annunciator, storer, overload values select module, operation push-button and A/D converter to be all electrically connected with single-chip microcomputer, charging circuit is electrically connected by super capacitor and delay switch, and measuring sonde is electrically connected by A/D converter and single-chip microcomputer.
Preferably, described display screen is LCD display.
Preferably, described storer is FLASH storer.
The utlity model has following beneficial effect:
Can store, display measurement data, and can take out when needed the data of preservation; While measuring overload, prompting capable of automatic alarm; The idle certain hour that surpasses, automatic shutdown, saves electric energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Novel universal table of the utility model preferred embodiment.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further.
As shown in Figure 1, a kind of Novel universal table, it comprises charging circuit, super capacitor, delay switch, single-chip microcomputer, display screen, audible-visual annunciator, storer, overload values selection module, operation push-button, A/D converter and measuring sonde, delay switch, display screen, audible-visual annunciator, storer, overload values select module, operation push-button and A/D converter to be all electrically connected with single-chip microcomputer, charging circuit is electrically connected by super capacitor and delay switch, and measuring sonde is electrically connected by A/D converter and single-chip microcomputer.
The display screen of the present embodiment is LCD display, and storer is FLASH storer.
Shown in overload values select module to be formed by several pull-up resistors and several pull down resistors.
During use, first connect civil power, make super capacitor charging, be full of after electricity, just can disconnect civil power.By operation push-button, start shooting, choose measurement gear, by overload values, select module to set overload values, by measuring sonde, measure, single-chip microcomputer is analyzed the signal from measuring sonde, and data are saved to storer, and shows by display screen, when signal overloading from measuring sonde, start audible-visual annunciator.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
