Variable monitoring system and method

The present invention relates to a monitoring system and method, and more particularly to a variable monitoring system and method for monitoring a variable parameter of a processing machine.

In the industrial application field, it is often necessary to transmit the current work information of the processing machine to a human-machine interface, so that the operator can understand the working state of the processing machine, determine whether the manipulation of the processing equipment is in place, and make appropriate adjustments. Generally, the working information of the processing machine includes plural variable parameters, such as motor speed, torque, load rate, etc., when the number of variable parameters to be processed is too large, the update frequency of the work information displayed on the human-machine interface is reduced. The operator is unable to timely process the parameters that need to be adjusted according to the displayed information, resulting in problems such as low processing accuracy and poor working efficiency of the processing equipment.

A variable monitoring method for monitoring a working state of a processing machine includes the steps of: selecting a certain number of variable parameters of the processing machine; and setting an update frequency of a corresponding variable parameter according to the selected number of variable parameters; Converting the selected variable parameter into a specific format information packet, and transmitting the information packet of the variable parameter to a central processing unit according to the update frequency; the central processing unit collects the value of the selected variable parameter; determining whether to collect After completing the values of all the selected variable parameters, if the collection of the values of all the selected variable parameters is not completed, the step of converting the variable parameters into information packets is returned; if the values of all the selected variable parameters are completed, Displays the values of all selected variable parameters.

The variable monitoring system and method of the present invention avoids the problem of low update frequency caused by processing all variable parameters by selecting the variable parameters of the processing machine and setting the update frequency of different variable parameters according to the number of selected variable parameters. Improve the working efficiency of the processing machine.

Referring to FIG. 1, a preferred embodiment of the variable monitoring system of the present invention includes a variable selecting unit 12, a frequency adjusting unit 14, and a first communication pass. The output unit 16, a numerical processing unit 18, a central processing unit 22 and a second communication transmission unit 24, the variable selection unit 12, the frequency adjustment unit 14, the first communication transmission unit 16, and the numerical processing unit 18 are all disposed in one In the human machine interface 10 of the processing machine, the central processing unit 22 and the second communication transmission unit 24 are all disposed in one of the processing machines 20, the variable selection unit 12, the first communication transmission unit 16, and the central processing The unit 22, the second communication transmission unit 24, and the numerical processing unit 18 are sequentially connected, and the frequency adjustment unit 14 is connected to the variable selection unit 12 and the first communication transmission unit 16. The variable monitoring system can be controlled through an operation interface disposed in the human machine interface 10.

By operating the operation interface, the variable selecting unit 12 can select any number of variable parameters from all the set variable parameters, and the frequency adjusting unit 14 sets the corresponding parameter update frequency according to the selected number of variable parameters, and selects the variable parameter. The smaller the number, the higher the update frequency of the variable parameter, the first communication transmission unit 16 converts the selected variable parameter into a specific format information packet, and according to the update frequency set by the frequency adjustment unit 14, the information is used. The packet is transmitted to the central processing unit 22, which collects the value of the selected variable parameter and transmits it to the numerical processing unit 18 via the second communication transmission unit 24, which processes and displays all of the The value of the variable parameter is selected for reference by the operator, and the operator can further process and update the selected variable parameter according to the value of the displayed variable parameter.

Referring to FIG. 2, the variable monitoring method of the present invention is applied to the variable monitoring system of FIG. 1. The preferred embodiment includes the following steps: Step 100: By operating the operation interface, the variable selection unit 12 selects a certain number of variable parameters from all the set variable parameters.

Step 200: The frequency adjustment unit 14 sets an update frequency of a corresponding variable parameter according to the selected number of variable parameters.

Step 300: The first communication transmission unit 16 converts the selected variable parameter into an information packet of a specific format, and transmits the information packet to the central processing unit 22 according to the update frequency. For example, when the frequency adjustment unit 14 sets the update frequency to 1/3 times per second, the communication transmission unit 16 transmits an information packet of a variable parameter to the central processing unit 22 every 3 seconds.

Step 400: The central processing unit 22 collects the value of the selected variable parameter.

Step 500: Determine whether the values of all the selected variable parameters are collected. If the collection of the values of all the selected variable parameters is not completed, return to step 300.

Step 600: If the acquisition of the values of all the selected variable parameters has been completed, the second communication transmission unit 24 transmits the values of all the acquired variable parameters to the numerical processing unit 18.

Step 700: The value processing unit 18 processes and displays the values of all the selected variable parameters. For example, the value processing unit 18 can convert the received hexadecimal digits into decimal digits that can be easily observed by the operator and display On the screen of the human machine interface 10.

In this embodiment, the operator can select a smaller number of important variable parameters from all the set variable parameters, so that a faster update frequency can be obtained. Rate, to monitor the selected variable parameters, and the number of variables selected by the operator each time can be different, so the update frequency of the variable parameters can be appropriately adjusted according to the number of selected variable parameters, when it is not necessary to speed up the update frequency, The variable parameter may not be selected, and the values of all the set variable parameters are displayed to the operator at a preset frequency.
