Example 2
The present embodiment is different from embodiment 1 in that,
step S22, acquiring product information of a machined workpiece of the current production equipment, includes the following steps:
s221, after transmitting the specific machining program to the device address corresponding to the current production device, obtaining the model of the product based on the specific machining program.
S222, acquiring the number of times the specific machining program is loaded to obtain the number of products.
S223, cumulatively recording the model and quantity of the product, and updating the product information.
Specifically, the server 1 recognizes the machining program in the control panel 2 to know the model of the workpiece currently being machined by the production equipment. Meanwhile, the server 1 obtains the loading times of the processing programs in the control panel 2 so as to obtain the number of the workpieces of the current model; namely, the production equipment can produce a workpiece with the current model after loading the machining program once. The server 1 accumulatively records the model and number of the work pieces and updates the product information.
For example, after the server 1 sends the processing program a1 to the control panel 2, the server 1 obtains that the model of the product is a 1; meanwhile, the server 1 acquires that the machining program a1 is loaded N1 times to obtain the number of products N1. At this time, the product information is product a1 for N1 pieces. Then, the server 1 sends the processing program a2 to the control panel 2, and the server 1 obtains the product model a 2; meanwhile, the server 1 acquires that the machining program a2 is loaded M1 times to obtain the number of products M1. At this time, the server 1 updates the product information to N1 pieces of product a1 and M1 pieces of product a 2.
Step S40, after sending the specific machining program to the device address corresponding to the current production device, further includes the following steps:
and S50, acquiring the loading state of the specific machining program.
Specifically, the loading state is normal loading, no loading or loading interruption.
And S60, judging the running state of the current production equipment based on the loading state.
And under the condition that the loading state is normal loading, judging that the running state of the current production equipment is normal.
And under the condition that the loading state is not loaded, judging that the running state of the current production equipment is possibly abnormal, and sending out a warning after the unloaded state is maintained for a preset time.
And under the condition that the loading state is loading interruption, judging that the running state of the current production equipment is abnormal, and immediately sending out a warning.
S70, recording abnormal data when the loading state is loading interruption; the abnormal data comprises an equipment address, a specific processing program and an abnormal time.
And the loading state is the current moment of loading interruption, namely the abnormal moment.
S80, based on the abnormal data, a first abnormal frequency corresponding to the same equipment address and a second abnormal frequency corresponding to the same machining program are calculated.
And S90, acquiring the first abnormal frequency and/or the second abnormal frequency, and sending out prompt information based on a preset prompt mechanism.
In one embodiment, the first abnormal frequency is the number of load interrupts at the production device corresponding to the same device address within a preset time period. For example, if 3 loading interruptions occur in the current production equipment within one month, the first exception frequency is 3. And the machining programs in which the loading interruption occurs may be the same or different. The second abnormal frequency is the frequency of loading interruption corresponding to the same machining program in a preset time period.
At this time, the prompting mechanism is as follows: the first abnormal frequency is larger than a threshold value; the second anomaly frequency is greater than a threshold. Meanwhile, in the case where the first abnormality frequency is greater than the threshold value, the server 1 outputs device information corresponding to the device address as the prompt information. In the case where the second abnormal frequency is greater than the threshold, the server 1 outputs workpiece information corresponding to the machining program as prompt information, such as: product a1 program exception.
In another embodiment, the first exception frequency is the time interval between 2 load interrupts occurring at a production device corresponding to the same device address. For example, if the current production device has a first load interrupt in month 3 and 9, and then the current production device stably operates, and the current production device has a second load interrupt in month 3 and 19, the first abnormal frequency is 10 days. The second anomaly frequency is the time interval between 2 load interruptions corresponding to the same process.
At this time, the prompting mechanism is as follows: the first abnormal frequency is less than a threshold value; the second anomaly frequency is less than the threshold. Meanwhile, in the case where the first abnormality frequency is less than the threshold, the server 1 outputs the device information corresponding to the device address as the prompt information. In the case where the second abnormality frequency is less than the threshold, the server 1 outputs workpiece information corresponding to the machining program as prompt information, such as: product a1 program exception.
The implementation principle of the embodiment 2 is as follows: recording the model and the quantity of the produced products based on the loading state of a specific processing program; meanwhile, whether the production equipment has an unobvious problem or not is judged or not, whether the machining program is carefree or not is judged based on the loading state of the specific machining program, and then the production equipment is maintained in time or the machining program is updated in time, so that safe and efficient production is guaranteed.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
