Intelligent four-in-one machine

4. Machine tool transfer module

The lowest part of the control cabinet is the machine transfer module. The machine tool transfer module is a cable connection unit between each machine tool and the semi-physical object. There are terminal blocks and aviation plugs on the panel to connect with semi-physical objects.

5, JGWW-GX2.0 networked intelligent wireless communication assessment and identification management system

The assessment system uses the JGWW-GX2.0 networked intelligent wireless communication training assessment management system, written in language, and uses dynamic database linking technology. It can link student information, student grades, test paper management, test plans, fault databases, etc. And queries. Equipped with fault assessment system (LCD display and button unit); start, stop, emergency stop buttons; an AC voltmeter, voltage indication switch and power switch, the computer software uses Visual Basic.

The JGWW-GX2.0 management system can set up to 255 lower computers.

The JGWW-GX2.0 management system uses wizard-style new projects to effectively avoid problems such as tedious data modification or data leakage.

The host computer adopts USB wireless communication mode to exchange information and data with the host computer in real time. The management system software can monitor the working status of each host computer in real time.

The lower computer uses a single-chip microcomputer to control the fault. Students can only judge the fault by the fault phenomenon, and then troubleshoot the fault by entering the fault line number. If the fault line number is entered correctly, the fault is automatically cancelled.

The lower computer can design the fault for evaluation independently from the control of the upper computer. After the evaluation, the final result of the student is displayed on the LCD.

Three-phase power input. After the leakage protector, the contactor is controlled by the start and stop buttons to operate the total power output of the machine tool circuit. The emergency stop button is used as an emergency stop switch when an accident occurs.

The failure assessment system has 20 switches, of which K1 to K20 are used for failure setting. The interface is connected with the host computer, and the fault points can be set at will for fault assessment. In the test, the fault can be set by the instructor, and the students can detect and test to find out the fault. In the experiment, it can be detected through the test points on the panel and the normally open and normally closed contacts of the contactor.
