Description

 Productivity calculation method for application line

 Technical field

 The method of the present invention is a solution to the productivity of computing devices in the semiconductor industry. Specifically, the production line of the packaging production line monitors the production of multiple devices. Some of the multiple devices are not produced around the clock, but are sometimes produced and sometimes idle. Therefore, the present invention is to count the production and idleness of these devices.

 Background technique

 At present, semiconductor manufacturing plants are becoming more and more automated, and the use of semiconductor manufacturing equipment has always been highly valued by semiconductor manufacturing plants because of the plant's capacity and output. The packaging line host can communicate with each device in the production line in real time to obtain the production status change data reported during the production process. However, these data are changes in the production status of the recording equipment, and the data is very scattered. How to calculate the equipment productivity data that the factory managers want from these state change data becomes a major difficulty.

 Summary of the invention

 In view of the communication characteristics of the main line and equipment of the packaging production line, the present invention provides a software solution for realizing the productivity calculation of the packaging production line, and provides a very specific calculation method for the productivity of the packaging production line.

 Step 1, the packaging production line host establishes an initial connection with the device;

 Step 2: When the connection is successful, record the real-time time and the current production status of the device;

 Step 3: When the production status of the device changes, the time of the previous production state is counted;

 Step 4: Modify the start time and production status of the new production state of the device in the memory;

 detailed description

 A productivity calculation method applied to a packaging production line, which analyzes and processes the production status change event message reported by the device, and calculates the productivity during the work process for each device.

 Includes the following steps:

 Step 1, the packaging production line host establishes an initial connection with the device;

 Step 2: When the connection is successful, record the real-time time and the current production status of the device;

 Step 3: When the production status of the device changes, the time of the previous production state is counted;

 Step 4: Modify the start time and production status of the new production state of the device in the memory;

 Step 5: Calculate the ratio of each production state to the total time of the statistics.

 In the step 1, the package production line host establishes an initial connection with the device; the package production line host performs a series of initialization settings on the device, for example, enabling device event message reporting; ensuring that the package production line host can normally communicate with the device, and the device The data required to package the production line host can be provided normally. If the initial connection fails, the encapsulated production line host repeatedly tries to connect to the device until the device goes online and counts the time for the Offline state.

 In the step 2, after the package production line host establishes an initial connection with the device, the current time and the current device production status are stored in the memory.

 In the step 3, when the production state of the device changes, the duration of the previous production state is counted; the duration is the difference between the current time and the start time of the previous production state stored in the memory.

In the step 4, the device new production state start time and the production state are modified in the memory; the memory is stored in the memory The start time of the previous production state and the previous production state are modified to the current time and the current production state.

 In the step 5, calculating the ratio of each production state in the total time of the statistics; dividing the time accumulation result of each production state counted in step 3 by the total time of the statistics, and obtaining the ratio of each production state .

 When the production status of the device changes, it is sent to the package production line host as an event message. The packaging production line The host can know the current production status of the current equipment. There are four production states for the device: NotReady, Ready, Executing, Offline When the device is in the NotReady and Ready states, the device is not producing. When the device is in the Executing state, it indicates that the device is in production. When the device is in the offline state, it indicates that the device is not managed by the packaged production line host. The calculation result of the present invention is the ratio of these four states in the total time of the statistics.

 When the package line host and device initialization connection is successful, the variable is set to record the current production state initial time and the current production state, after which each of the production state changes will update these two variables. When the production status of the device changes, an event message indicating the change of the production status is reported, and the time of the previous production state is recorded. The real-time time when the production line change information is received by the packaging line host minus the start time of the previous production state is the duration of the previous production state, and then the duration of the same state is accumulated.

 As shown in Figure 1: The host of the packaging production line is initialized with the device. If the connection is successful, the real-time time is recorded and the current production status of the device. When the production status of the equipment changes, the previous production status duration is recorded. Modify the new production status of the device and the start time of the production status in memory. The ratio of each production state to the total time of the statistics is counted. If the connection fails, the time is accumulated for the Offline state.

 As shown in Figure 2: The package production line host and the device are initially connected. If the connection is successful, the current time and current production status are stored in the variable. When the production status of the device changes, if the previous production status is the Executing state, the current time is compared with the previous Executing state initial time, and the result is added to the Executing state time. If the previous production status is not Executing, it is the other production status. Accumulate time. If the connection fails, the time is accumulated for the Offline state.

 As shown in Figure 3: The package production line host and the device are initially connected. If the connection is successful, the package production line host records the current time and the current production status. When the production status of the device changes, if the previous production status is NotReady or Ready, the current time is compared with the last time of the previous NotReady or Ready state, and the result is added to the NotReady or Ready state time, if the previous When the production status is not the NotReady or Ready status, the time is accumulated for other production states. If the connection fails, the offline state is accumulated.
