System and method for monitoring variable parameters out of working parameters of processing machine

A system for monitoring variable parameters out of working parameters of a processing machine includes a selecting module, a frequency updating module, a first communicating module, a central processing unit (CPU), and a value processing module. The selecting module selects a number of variable parameters out of working parameters of the processing machine. The frequency updating module sets an updating frequency of the selected variable parameters according to the number of the selected variable parameters. The first communicating module converts the selected variable parameters into appointed formats. The CPU receives the converted variable parameters at the updating frequency, and gather the values of the received variable parameters. The value processing module receives the values of the selected variable parameters, and transforms the values of the selected variable parameters to display formats for presentation.

BACKGROUND

1. Technical Field

Embodiments of the present disclosure relate to monitoring systems and methods and, particularly, to a system and a method for monitoring variable parameters out of working parameters of a processing machine.

2. Description of the Related Art

For industrial control processes, human machine interfaces (HMIs) are used for monitoring and modifying the working parameters of industrial machines like processing machines, motor etc. The working parameters of a processing machine include variables parameters, such as the rotate speed, the torque of a motor of the processing machine, which are normally monitored by users via a screen of the HMI. Unfortunately, users may not be able to monitor and modify the variable parameters in time if a great number of the variable parameters are being processed and displayed by the HMI, which may cause production problems.

What is needed, therefore, is to provide system and method for monitoring variable parameters, to overcome the above-mentioned shortcoming.

DETAILED DESCRIPTION

Referring toFIG. 1, one embodiment of a system1for monitoring variable parameters of a processing machine (not shown) includes a memory module11, a selecting module12, a frequency updating module14, a first communicating module16, a value processing module18, a central processing unit (CPU)22, and a second communicating module24. The memory module11, the selecting module12, the frequency updating module14, the first communicating module16, and the value processing module18are located in a human machine interface (HMI)10of the processing machine. The CPU22and the second communicating module24are located in a driving device20of the processing machine. The memory module11, the selecting module12, the first communicating module16, the CPU22, the second communicating module24, and the value processing module18are connected in series. An input terminal of the frequency updating module14is connected to the selecting module12. An output terminal of the frequency updating module14is connected to the first communicating module16.

The memory module11stores the variable parameters of the processing machine. The selecting module12is controlled by a user interface of the HMI10, and is configured to select a number of the variable parameters. The frequency updating module14changes or sets an updating frequency of the selected variable parameters via the user interface. A higher updating frequency is obtained upon the condition that the number of the selected variable parameters is decreased. The selected variable parameters are converted into predetermined formats by the first communicating module16. The converted variable parameters are transmitted to the CPU22at the updating frequency set by the frequency updating module14. Values of the selected variable parameters are gathered by the CPU22, and are transmitted to the value processing module18via the second communicating module24. The values of the selected variable parameters are processed by the value processing module18, and are finally displayed on the HMI10.

Referring toFIG. 2, one embodiment of a method for monitoring variable parameters of the processing machine is used to observe and control the variable parameters of the processing machine by a user.

In step100, a user interface is used to control the selecting module to select a number of the variable parameters from all of the working parameters of the processing machine stored in the memory module. The selected variable parameters may be especially important during the processing machine operations.

In step200, the frequency updating module14sets an updating frequency of the selected variable parameters. A higher updating frequency could be set upon the condition that the number of the selected variable parameters is less than before.

In step400, the values of the selected variable parameters are gathered by the CPU22.

In step500, determine whether all of the values of the selected variable parameters are gathered by the CPU22. If the gather of all of the selected variable parameters values has completed, step600is executed. Otherwise, if there is any of the selected variable parameters values has not been gathered, the flow returns to step400.

In step600, values of all of the selected variable parameters are transmitted to the value processing module18from the CPU22via the second communicating module24.

In step700, processing and displaying the values of the selected variable parameters. Processing may, for example, include hexadecimal-to-decimal conversions. The processed values may be displayed on a screen of the HMI10.

In this embodiment, the number of the selected variable parameters can be changed as desired at each time when setting the updating frequency. The number of the selected variable parameters can be unchangeable, therefore, without the need of using the user interface when a higher or lower updating frequency is unnecessary.
