Abstract

The invention discloses an electronic controller of an electric pulsation milking machine. The controller not only comprises a power supply circuit, an electronic switch circuit and a load short circuit protection circuit, but also comprises a 12V working power supply protection circuit composed of a fifth not gate of an IC1, a sixth not gate of the IC1 and a field effect transistor BG1. According to the electronic controller, the integrated circuit with the six not gates is used as the IC1, a square-wave generator is composed of the first not gate of the IC1, the second not gate of the IC1, a resistor R3, a resistor R4, a charging and discharging capacitor C3 and a charging and discharging capacitor C4, the third not gate of the IC1 is used as an isolation level, the fourth not gate of the IC1 is used as a phase inverter to complete the alternate pulsation signal output of another circuit, the working power supply protection circuit is composed of the fifth not gate of the IC1, the sixth not gate of the IC1 and the field effect transistor BG1 and protects a three-end voltage stabilization power supply L7812 and a resistor R1, and therefore the problem that a circuit board of the whole machine is burnt due to the fact that the temperature of the three-end voltage stabilization power supply L7812 and the temperature of the resistor R1 are kept excessively high can be effectively solved, and both working performance and working efficiency of the controller can further be ensured and improved.

Description

technical field [0001] The invention relates to milking equipment, in particular to an electronic controller for an electric pulsation milking machine. Background technique [0002] The electric pulsation milking machine has a market advantage because of its stable pulsation frequency, fast milking speed and high milk production, and the electronic controller is an essential key component of the electric pulsation milking machine equipment, but the current market The electric pulsator milking machine has a complicated control circuit and no load short-circuit protection. When the pulsator has a short-circuit fault, it cannot automatically cut off the power and cause damage to the controller, which not only affects normal milking, but also increases costs. [0003] The Chinese patent number is 200920101007.7, and the load short-circuit protection circuit designed in the utility model patent named "Electronic Controller for Electric Pulsation Milking Machine" protects the circ...
