Description

Centralized measuring system

Technical Field

The utility model relates to a universal meter field, in particular to utilize polylith universal meter simultaneous measurement object's different signals and concentrate measurement system that gets up with the measuring result respectively.

Background

The multimeter is a magnetoelectric instrument with a rectifier and capable of measuring a plurality of electrical parameters such as alternating current, direct current, voltage, resistance and the like. For each electrical quantity, there are typically several ranges. Also called a multipurpose meter or simply a multipurpose meter. The multimeter is composed of a magnetoelectric system ammeter (meter head), a measuring circuit, a selection switch and the like. By changing the selection switch, various electrical parameters can be conveniently measured. The main basis for the circuit calculation is closed circuit ohm's law. Multimeters are of various types and can be selected according to different requirements when in use.

IN order to simplify the operation of the multimeter, a multimeter operated by sound control is provided IN the industry, and the Chinese utility model authorized bulletin document No. CN 205158054U discloses a control circuit of the sound control multimeter, which comprises a battery pack, a microphone, a triode, a singlechip, a level control circuit, a coupling capacitor and a backlight source circuit, wherein the output end of the battery pack is respectively connected with the microphone, the collector of the triode, the input end of the level control circuit and the VDD port of the singlechip, one end of the coupling capacitor is connected with the microphone, the other end of the coupling capacitor is connected with the base of the triode, the CDS port of the singlechip is connected with the output end of the level control circuit, the IN port of the singlechip is connected with the collector of the triode, the emitter of the triode is grounded, one end of the backlight source circuit is connected with the OUT port of the singlechip, and the other end of the backlight circuit and the GND port of the singlechip are both grounded.

The control circuit of the acoustic control multimeter can control the multimeter to be started and shut down, so that the multimeter is more convenient to operate.

However, when a multimeter is used at present, each meter can only measure one parameter at the same time, although a plurality of multimeters can be used for measuring a plurality of same or different parameters of a measured object at the same time, for example, one multimeter is used for measuring the total input current of a device, one multimeter is used for measuring the total voltage of the device, one multimeter is used for measuring the resistance of a certain part of the device, and a plurality of multimeters are used for measuring the current, the voltage and the like of other parts of the device.
