Description

The fully automatic wire winding machine control protection electric circuit

Technical field

The utility model relates to the coiling that is used to make coil, relates in particular to the control and the protection of fully automatic wire winding machine electric-control system.

Background technology

The host computer control part technology of existing automatic coil winding machine is improved inadequately and is advanced, mainly shows following several aspect, at first, lacks self check, protective circuit on the monoblock circuit board, has increased difficulty to failure judgment in maintenance, that is has been difficult to search fault; Secondly, CPU working power and driving power are supplied with by a power supply, cause the control spread of voltage, and the drive part short circuit also can influence the CPU power supply; Erasable in addition button does not add the DIP functional switch, and mechanical oscillation or faulty operation all cause being wiped free of of program and data easily; And the PLD logical circuit do not plug defectives such as socket, caused difficulty all for the safe handling of coil winding machine.

Summary of the invention

The purpose of this utility model is, a kind of control protection electric circuit of fully automatic wire winding machine is provided, and is intended to the main control computer wiring board is improved on the existing structure basis, makes it have more stability and practicality on function.

The technical solution of the utility model is achieved in that

A kind of fully automatic wire winding machine control protection electric circuit, comprise CPU2 central controller, PLD logic control circuit and LCD display, it is characterized in that comprising CPU1, protection and self-checking circuit that is used for System self-test and the independent current source circuit that is separated with original driving and control power supply, wherein said CPU1 is connected with CPU2 by MOSI, MOSO, SGFZ, SGZD pin, be connected with overvoltage protection, overcurrent protection and electromagnetic braking circuit with the ZD pin by its ZZ, FZ, be connected with serial interface circuit by RXD, TXD pin; Simultaneously, described CPU1 also is connected with PLD logic control circuit and/or LCD display circuit respectively by FX1, FX2, FX3 and FX4 and SIN, SCKL, SCLR and RCK pin with CPU2.

The package design of described PLD comprises the compatibility to three kinds of encapsulation of PLCC/DIP/QFP.

Compared with prior art, the utility model has the advantages that conspicuously, mainly show:

(1) the original product program pushbutton is added pulls out a yard lock function.

(2) fly part, fly line etc. on original mainboard and make the mainboard overall appearance bad, cause the mainboard poor stability.After improving, mainboard has expansions such as chip and exclusion, wire jumper pin to be reserved, and can be used in multiple model coil winding machine mainboard control system, makes the mainboard overall appearance regular, has improved stability.

(3) be added with independently-powered and master control two cover power supplys, guaranteed the error checking function of CPU, make it have each road input, output short-circuit, open circuit detection and warning function, make the mainboard more stable work.
