The utility model is applicable to the field of industrial control and provides a touch screen control circuit in an embroidery machine system. The touch screen control circuit comprises a touch control circuit which is connected with a touch screen of an embroidery machine, a communication interface circuit which is connected with a main control board of the embroidery machine, a single chip microcomputer with an AD conversion function and a power supply circuit which supplies power to the above three circuits. The single chip microcomputer with the AD conversion function is connected with the touch screen control circuit through an AD acquisition pin of the single chip microcomputer, and is also connected with the communication interface circuit. According to the touch screen control circuit, through the employment of an STC12C5A08AD single chip microcomputer, a 10-bit AD carried by the single chip microcomputer is taken as a touch screen acquisition port, and the single chip microcomputer sends acquired touch information or button information to a main control system through a standard RS485 interface. The whole scheme has the characteristics of fast response, high sensitivity, low cost and strong versatility.
