Element symbols quoted in the following description will be regarded as the same or similar elements when the same element symbols appear in different drawings. These examples are only a part of the invention and do not disclose all possible embodiments of the invention. Rather, these embodiments are merely exemplary of apparatus and methods within the scope of the present invention.

Please refer to FIG. 1 , which is a schematic diagram of an apparatus for monitoring equipment performance according to an embodiment of the present invention. In this embodiment, the device performance monitoring apparatus 100 is coupled to the devices E1 and E2 to monitor the devices E1 and E2. The equipment E1, E2 may be any manufacturing equipment or production equipment. In this embodiment, the device performance monitoring device 100 includes a monitoring module 110 , an analysis module 120 and a control module 130 . The monitoring module 110 communicates with the devices E1 and E2. The monitoring module 110 obtains the status of the equipment E1 and E2 through the operation status of at least one device of the equipment E1 and E2, and provides operation status information SI1 and SI2 related to the equipment E1 and E2 according to the status of the equipment E1 and E2. For example, apparatus E1 includes devices D1-D3. The devices D1 to D3 may be input devices or human-machine interfaces. The device D1 is, for example, a button, the device D2 is, for example, a keyboard or a mouse, and the device D3 is, for example, a human-machine interface. The corresponding operation message IF1 will be provided when the devices D1 to D3 are operated or not. The monitoring module 110 will continue to receive the operation message IF1 to know the status of the equipment E1, and accordingly provide the operation status message SI1 of the equipment E1. Therefore, the operation state information SI1 is related to the operation information IF1 of the devices D1 to D3. Similarly, the monitoring module 110 will continue to receive the operation message IF2 to learn the status of the equipment E2, and accordingly provide the operation status information SI2 of the equipment E2. The operation status message SI2 is related to the input device of the equipment E2 or the operation message IF2 of the man-machine interface.

For convenience of description, this embodiment takes two devices E1 and E2 as an example. The device performance monitoring apparatus 100 of the present invention can monitor one or more devices, and the number of devices in this embodiment is not limited.

In this embodiment, the analysis module 120 is coupled to the monitoring module 110 . The analysis module 120 receives the operation status messages SI1 and SI2. The analysis module 120 generates the performance information EE1 corresponding to the equipment E1 according to the operation status information SI1, and generates the performance information EE2 corresponding to the equipment E2 according to the operation status information SI2. For example, the analysis module 120 integrates the operation status information SI1 of a specific time length (one day, one week, one month, one season or one year) to generate the performance information EE1 corresponding to the equipment E1. The analysis module 120 also integrates the operation status information SI2 to generate the performance information EE2 corresponding to the equipment E2. In this embodiment, the performance information EE1 may be an Overall Equipment Effectiveness (OEE) report related to the equipment E1 or information displayed on an output device (not shown) of the equipment performance monitoring device 100 . The performance information EE2 may be a report of the overall equipment efficiency related to the equipment E2 or information displayed on the output device of the equipment performance monitoring device 100 .

It is worth mentioning here that the device performance monitoring device 100 can know the device E1 through the actual operation status of at least one input device (such as the device D1, D2) and at least one man-machine interface (such as the device D3) of the devices E1 and E2 , E2 status, so as to provide corresponding operation status information SI1, SI2. In this way, the device performance monitoring apparatus 100 can obtain the real performance information EE1 and EE2 according to the operation status information SI1 and SI2.

In this embodiment, the control module 130 is coupled to the analysis module 120 and the devices E1 and E2. The control module 130 receives the operation status messages SI1 and SI2. The control module 130 controls the equipment in the idle state to enter the production state according to the operation state information SI1, SI2 and the intervention script ITSC. Through the intervention of the control module 130, the performance of the devices E1 and E2 can be improved.

In this embodiment, the monitoring module 110 and the control module 130 can respectively perform wired communication or wireless communication with the devices E1 and E2.

In this embodiment, the operation status messages SI1 and SI2 respectively include idle messages. The intervention script ITSC records at least one script that allows the control module 130 to perform an intervention operation on the device in the idle state. For example, the analysis module 120 will determine the idle state of the equipment E1 according to the display message related to the human-machine interface (such as the device D3 ) and the operation status that the confirmation operation has not been performed for a long time, so as to know the idle reason of the equipment E1, and The idle message corresponding to the equipment E1 is provided according to the idle reason of the equipment E1. Therefore, the control module 130 knows that the equipment E1 has entered the idle state through the idle information of the operation state information SI1, and can use an input operation to enter the production state. The above-mentioned idle state is confirmed to be the suspended state of the operation in which the equipment E1 is ready to enter the next stage, and the above-mentioned confirmation operation is an input operation to enter the next stage. The above idle state corresponds to one of the scenarios in the intervention scenario ITSC. Therefore, the control module 130 provides the control signal CS1 to complete the input operation to the equipment E1. Equipment E1 enters the production state. As a result, the efficiency (or availability) of the equipment E1 will increase. In addition, through the intervention operation of the control module 130, the equipment performance monitoring apparatus 100 can also prevent the misoperation of the equipment E1 and E2.

In this embodiment, the monitoring module 110 , the analysis module 120 , and the control module 130 are, for example, electronic devices, components (eg, a microprocessor (Microprocessor), a digital signal processor (DSP) with computing functions ), programmable controllers, Application Specific Integrated Circuits (ASICs), Programmable Logic Devices (PLDs), or other similar devices or combinations of these devices) or devices with similar computing functions program.

Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 2 is a schematic diagram of the overall equipment efficiency of the equipment. The time length T10 is represented as the total available time length. The time length T10 includes time lengths T20, T21, and T22. The time length T20 is represented as the planned working time length. The time length T21 is represented as the maintenance time length. The length of time T22 is represented as the length of downtime. The time lengths T21, T22 are the planned time lengths for which the equipment is expected to stop production. The time length T20 includes time lengths T30 and T31. The time length T30 is represented as the net working time length. The length of time T31 is expressed as the length of time for the loss of availability, eg, the length of time it takes for the operator of the equipment to be handed over, to change the shift. That is, the net working time length is the result of the planned working time length minus the length of time lost in availability. The time length T30 includes the time lengths T40 and T41. The time length T40 is represented as the gross production time length. The length of time T41 is represented as the length of time lost in performance, for example, the length of time it takes for the operator to eat or rest. That is, the gross production time length is the result of the net work time length minus the performance loss time length. The time length T40 includes the time lengths T50 and T51. The time length T50 is represented as the net production time length. The length of time T51 is expressed as the length of time for quality loss, eg, the length of time that the equipment waits for confirmation from the operator during production.

It should be noted that the time lengths T31, T41, T51 may be extended due to unforeseen circumstances. The extension of time lengths T31, T41, and T51 is an invisible loss that cannot be detected by current equipment performance monitoring. The actual operating conditions of the input device or human-machine interface of the equipment E1 and E2 will faithfully reflect the real usability loss, the real performance loss and the real quality loss of the equipment E1 and E2. Therefore, the equipment performance monitoring apparatus 100 can obtain the real performance information EE1 and EE2.

In this embodiment, after obtaining the performance information EE1 and EE2, the analysis module 120 can analyze the defects of the production process of the equipments E1 and E2. The analysis module 120 updates the production process of the equipment E1 and E2 according to the performance information EE1 and EE2, thereby optimizing the efficiency of the equipment E1 and E2. In some embodiments, the analysis module 120 can also update the intervention script ITSC of the control module 130 according to the performance information EE1 and EE2.

Messages SI1, SI2. In step S120, the equipment performance monitoring apparatus 100 generates performance information EE1, EE2 corresponding to the equipment E1, E2 according to the operation status information SI1, SI2. In step S130, the device performance monitoring apparatus 100 determines whether the devices E1 and E2 enter an idle state. When the equipment E1 and E2 are not in the idle state, it means that the equipment E1 and E2 are both working (in production). Therefore, it returns to step S110.

On the other hand, for example, when the equipment E1 enters the idle state, the equipment performance monitoring apparatus 100 controls the idle equipment E1 to enter the production state according to the operation state information SI1 and the intervention script ITSC.

The equipment performance monitoring method of this embodiment can be applied to the equipment performance monitoring apparatus 100 . Steps S210 to S240 in the second embodiment can be sufficiently taught in the embodiments of FIGS. 1 and 3 , and therefore will not be repeated here. In this embodiment, the device performance monitoring apparatus 100 determines whether the status or production capacity of the devices E1 and E2 is abnormal in step S250. The equipment performance monitoring device 100 can determine whether the status or production capacity of the equipment E1 and E2 is abnormal through the display of the performance information EE1 and EE2 and/or the human-machine interface. For example, when the state of the equipment E1 is determined to be abnormal (eg, the raw material is about to be insufficient or the object is damaged, etc.), the equipment performance monitoring apparatus 100 will provide a state alarm in step S260. For another example, when the production capacity of the equipment E2 is determined to be abnormal (eg, the production capacity is lower than a threshold or the performance is lower than a preset performance), the equipment performance monitoring apparatus 100 provides a production capacity alarm in step S270. For another example, when the equipment E1 and E2 are not abnormal, the equipment performance monitoring apparatus 100 will return to the operation in step S210.
