Improvement of automatic performance of double liquid mixing machine system　

Mixing machine is a shaft with a blade rotating in a cylinder or groove, mixing a variety of raw materials to make it a mixture or a machine suitable for consistency. There are several types of mixer, a compulsory mixer, single horizontal shaft mixer, twin shaft mixer etc.. Attention: mixer and automatic feeder, must be cleaned inside, especially in winter, this can extend the life. Mixer is the mixer, because the mixer is usually the role of mixing and mixing all kinds of dry mortar, it is commonly known as mixer.

The use of single chip microcomputer in the double liquid mixing machine system greatly improves the automation performance of the system, realizes the flexible juice setting, and realizes the filling of different objects. However, the dual liquid glue machine system which works in the field environment will be disturbed by many external interference sources, which leads to the confusion of the SCM system: the mistake of the glue filling rhythm and the waste products. In order to improve the anti-interference ability, the combination of hardware and software of the double liquid mixing machine system is used to enhance the reliability of the mixing machine.

The power supply adopts the correct shielding and filtering techniques, suppress the interference signal isolation power series in the end. Between the primary and secondary isolation transformer with shielding layer isolation, reduce capacitance and improve the ability of anti common mode interference; because the power interference is the most harmonic, so the low-pass filter is used to filter the harmonic and improve power waveform second, the double liquid glue machine system to eliminate the interference by double T filter.

Add the power voltage monitor and the watchdog circuit at the same time. When the microcontroller system power supply undervoltage occurred transient, transient pulse Ding Raoshi, power supply voltage monitor can automatically detect the interference pulse, a reset signal to the SCM system in a timely manner, so that reliable reset chip. For other interference caused by single chip microcomputer "crash" phenomenon. The system uses "watchdog" circuit to single chip microcomputer from the dead cycle or flying out of the note. Into the normal mixing process.
