The alarm module adopts a contact type limit sensor and is used for limiting the movement limit, namely the stroke, of the double-station mechanical actuating mechanism. The two-machine six-direction control device is controlled by 12 limiting sensors respectively, when the two-machine six-direction control device exceeds a movement limit position, the limiting sensors are disconnected and feed back to a PLC (programmable logic controller) through electric signals, the PLC transmits the signals to a central control system through an altera bus, and the system receives the electric signals, generates alarm information and displays the alarm information on a touch screen.

1. if the collected voltage value is higher than the basic value, the height of the welding gun is reduced according to a certain step length to reduce the voltage value, and the difference between the collected voltage value and the basic value is reduced until the collected voltage value is leveled with the basic value;
2. if the collected voltage value is lower than the basic value, the height of the welding gun is increased according to a certain step length to increase the voltage value, and the difference between the collected voltage value and the basic value is reduced until the collected voltage value is leveled with the basic value;
3. if the collected voltage value is higher than the set maximum value, the PLC transmits an alarm signal to the central control module, the mechanical part and the power part of the equipment stop running, and the PLC sends out the alarm signal to wait for manual processing of personnel;

The laser scanning positioning module converts the distance value from the laser head to the measuring surface into a voltage value through the laser ranging sensor, and outputs a 0-5V voltage signal which linearly corresponds to the measuring range of the laser sensor to be 200-600 mm. The 0-5V analog voltage signal processed by the hardware filtering module is transmitted to the PLC voltage analog quantity acquisition module, the PLC voltage analog quantity acquisition module is converted into a digital signal, the digital signal is transmitted to the central processing unit through the altera bus after being processed by the PLC, and the central processing unit converts the transmitted signal into measurement surface curve information and transmits the measurement surface curve information to the display screen for display through the altera bus. In the displayed curve, the curve 1 is a reference curve, the curve 2 is a wear surface curve of the middle groove after use, and the height difference value of the two curves is the wear loss of the middle groove after use. And then comparing the difference value of the two curves to obtain the abrasion loss of each position of the middle groove, thereby obtaining the height of each position needing plasma surfacing repair. The height value of the middle groove to be repaired and the X, Y axial plane coordinate value are related to the welding parameters through an empirical formula, namely the welding parameters are changed according to the change of the height value to be repaired.
Referring to fig. 2, by comparing the measured curves, an operator can easily determine the wear condition of the middle groove on the display interface, and can determine the coordinates of the start position of the workpiece to be repaired relative to the X, Y axial plane of the repair device according to the curves.

The method for controlling the system for controlling the double-station plasma melting equipment of claim 7, wherein in step S1, the touch display screen or the remote controller transmits the parameters of the melting welding to the upper computer through the ethernet, and the upper computer judges and transmits the parameters of the start time, the melting speed, the melting track and the end time of the melting welding to the motion controller in the form of G codes to identify and perform corresponding actions.
9. The control method of the double-station plasma cladding equipment control system according to claim 7, wherein in step S5, the wear depths of corresponding parts of the middle groove of the scraper conveyor are measured and compared by a laser ranging sensor, and the upper computer calls a corresponding welding parameter program after judging the depths and converts the welding parameter program into a first control signal identified by a servo driver to perform cladding operation.
