[0110] 1. Operation monitoring;

[0111] After being powered on, the touch screen 16 enters the operation monitoring screen by default;

[0112] The contents displayed on the operation monitoring screen are as follows:

[0113] (1) Communication status: The current connection status between the touch screen 16 and the controller PLC. When it is flashing red, it means that the touch screen 16 is not connected to the controller PLC or the connection fails. At this time, the device cannot be operated through the touch screen 16; when it is always green, it means that the touch screen 16 is successfully connected to the controller PLC.

[0114] (2) Winding frequency setting HZ: used to set the frequency of the motor reducer 12 when it is working, ranging from 0 to 50HZ.

[0115] (3) Hose outer diameter MM: used to set the outer diameter of the hose; the outer diameter of the hose can be set according to the outer diameter of the actual reeled hose. If you want to have gaps between the arranged hoses, just increase this value.

[0116] (4) Set length M: When using fixed-length coils, fill in the required length here. If not using fixed-length coils, please set it to 0 or a relatively large value; during operation, when the real-time winding length is equal to the set length M, the system automatically stops.

[0117] (5) Real-time winding speed rpm: Displays the real-time speed of the winding core assembly 2.

[0118] (6) Real-time line speed M / S: Displays the real-time line speed of the reeling hose.

[0119] (7) Real-time reel length M: Displays the real-time length of the reeled hose.

[0120] 2. Parameter setting;

[0121] The parameter setting screen is used in the shutdown state; specifically includes:

[0122] (1) Positional expression MM;

[0123] Three proximity switches are installed on the cable arranger 316. The proximity switches at both ends of the cable arranger 316 are limit switches to protect the motor, lead screw, motor reducer 12, etc. from damage. The normal swing range is reciprocating between the two limit switches. The middle proximity switch is the mechanical zero point, also known as the origin switch. When the transmission mechanism mounting seat 4 is at the origin switch, the position is 0.00MM. When the transmission mechanism mounting seat 4 is on the left side of the origin switch, the position information is a negative value; when the transmission mechanism mounting seat 4 is on the right side of the origin switch, the position information is a positive value. Return to origin: Press the return to origin button, the transmission mechanism mounting seat 4 runs, and searches for the origin switch. When the origin switch is detected, the equipment stops automatically and the current position is changed to 0.00MM.

[0124] (2) Left and right wiring positions:

[0125] When the coil core assembly 2 is expressed in position MM, when the coil core assembly 2 is moved to the left position by the left quick move button of the pipe, the current position is stored as the left position by the transfer button. When the coil core assembly 2 is moved to the right position by the right quick move button of the pipe, the current position is stored as the right position by the transfer button. The left position and right position of the cable can also be changed manually. The left position of the cable is a negative value, and the right position of the cable is a positive value. If the position value is filled in incorrectly, the system will not work properly.

[0126] 3. Fault query;

[0127] (1) When an abnormality occurs, the fault query page will describe the cause of the abnormality in detail. After eliminating the abnormality, you can press the abnormality reset button to confirm the current abnormality.

[0128] (2) When there are too many abnormal information displayed, you can click the Clear Record button to clear all current abnormal records.

[0129] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
