Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a multi-channel magnification control method based on physical keys of a machine tool keyboard, and as shown in fig. 1, the method of the embodiment may include:
101, triggering any one of a plurality of channels as a current channel to a PLC through a machine tool keyboard physical key, wherein the plurality of channels correspond to respective numbers;
102, the PLC sends the number corresponding to the current channel to a numerical control system and caches the data corresponding to the previous channel;
103, the numerical control system receives the number corresponding to the current channel and displays the current channel through a human-computer interaction interface of the numerical control system;
104, sending a speed adjustment value to the PLC through a multiplying power switch, receiving the speed adjustment value corresponding to the multiplying power switch by the PLC, and adjusting the speed of the current channel according to the cache data and the speed adjustment value;
105, the PLC sends the speed information of the current channel adjusted by the multiplying power switch to a numerical control system;
and 106, receiving the speed information by the numerical control system, and displaying the speed information of the current channel on a man-machine interaction interface of the numerical control system.
Specifically, as shown in fig. 2, the multi-channel magnification control method for the physical keys of the machine tool keyboard in the embodiment is to solve the problem that the magnification value of the specified channel is controlled by quickly switching the magnification button in the multi-channel mode of the GNC numerical control system. The machine tool keyboard physical keys (K keys) are a group of function keys reserved on a function keyboard of a GNC numerical control system device, and are used for reserving function buttons for carrying out some later development, generally, four K0-K3 are provided, the K keys are associated with a PLC program, the PLC can monitor the states of the K keys, the PLC scans the states of the K keys, when one of the K keys is pressed down, a certain port of the PLC is triggered, and the PLC can generate corresponding actions. On the basis, the K keys are associated with one of the channels, the PLC sends a signal for specifically activating the multiplying power control of the channel to the CNC system and the HMI by pressing the K keys, when the multiplying power control knob is used, the currently activated channel multiplying power value is controlled, and the data of the previous channel is cached, so that other contents of the channel of the current system are not changed, and only the multiplying power of the current channel is modified.
Each K key is provided with a status indicator light, when the K key is pressed down, the indicator light on the key is lightened, the indicator light on the K key pressed down before is extinguished, so that the user can judge that the multiplying power control of the channel is activated by looking at the indicator light, and if all the K keys are not pressed down, the current system uses the multiplying power control of the current channel.
After each channel control is switched, there is a delay (5 seconds in this embodiment), and the user can modify the magnification of the specified channel through the magnification control knob in this time, and the system starts to use the magnification after the delay.
The selection of channel multiplying power control can be reset through resetting, all indicator lights of all K keys are turned off, and the multiplying power control of the current channel is enabled to take effect. As shown in fig. 3, the channel of the current system is channel 1, the key switch is channel 2 magnification control using the K2, the indicator light on the K2 button is turned on, and the HMI looks to see whether the switch is successful.
The invention switches the multiplying power of the appointed channel controlled by the multiplying power control knob on the numerical control system keyboard through the preset physical key K key, thereby not only being convenient and fast, but also avoiding HMI restart and data refresh, and bringing great freedom for subsequent development and operation of the numerical control system.
