Intouch offers a variety of powerful features that can be configured to meet the specific requirements of the user for operation, display and recording. In addition, in addition to its own database, Intouch also supports SQL language encounters, which can be easily connected to other databases. With the powerful features of Intouch, we can easily improve the program and design a more powerful and fault-tolerant PC monitoring system.
Preparation for the transformation situation 1. In order to make the entire process of the ingredients data from the raw material tank to the production site, it can be completely traced, and each batch of data needs to be unique. For this purpose, a variable is set: the batch number, which is a combination of the year, month, and day plus the number of the day's preparation. The batch number is automatically generated during the batching and is written into the database along with the ingredient data and passed down to the brewing tank and storage tank. In this way, from the brewing tank to the storage tank, the batching process can be determined according to the batch number, and the management program can be conveniently processed to facilitate the staff to check the fragrance preparation.
2. Distribute the smoked card to the brewing tank and storage tank. When cleaning, change the cigarette to “cleanedâ€, which is convenient for the operator to determine whether the tank has been cleaned or not. State makes some judgments. 3. Create a corresponding report in the database, write all important raw data into the database, including the state of the tank (for raw material tanks, for 24 hours, this state is also reflected in the historical trend of Intouch; for the modulation tank and storage tank , record in the batching and discharging.), important button information (such as ingredient start button, water button, sewage button, etc.), ingredient information (including raw material tank data for static scale measurement, mass flow meter discharge data, etc.), For later traceability of the production process.
Fault-tolerant aspect: Preventive handling of erroneous operations from the entire production process: (1) In the case of ingredients, the raw material tank should not be in the suction state: in the application script, when the program is running, the raw material tank capacity is checked every second, if the capacity Increase, then set the flag. At the time of discharge, check the status of the flag to determine if it can be discharged. Code: IFYW_Y1>TEMP_Y1+1.0THENFlag_JL.00=1; TEMP_Y1=YW_Y1; ID_Y1=0; ELSEID_Y1=ID_Y1+1; IFID_Y1>5THENFlag_JL.00=0; ID_Y1=0; ENDIF; if the raw material tank can be discharged, according to the selected smoke The quantity of the corresponding raw material tanks retrieved in the card pop-up database should be convenient for the operator to check and confirm. Next, check if the selected preparation tank is available. If it is detected that the status is not the empty tank that has been cleaned (if the tank 1A is selected, the script is: IFPH_1A=="Cleaned" ANDYW_1A<23, the grade setting is used here), the alarm prompts, confirmation can be performed (the same The grade of material may not be cleaned.) Finally, when the leaf material is hydrating, check whether there is cleaning tank operation (because the spice kitchen water and washing water of our factory are the same pipeline), to avoid mistakes in water supply. When a batch of spices is not formulated, the next batch of perfume cannot be formulated.
Ease of use: It is possible to implement some functions that are convenient for the operator to operate and prevent the wrong operation to a certain extent. (1) Store the name of the raw materials stored in the raw material tank in the database, and provide the modification function according to the operation authority in the window, so that the management personnel can modify the name of the raw material in time according to the situation. (2) Automatic shift change, which is convenient for inquiring about the ingredients of each class. (3) The data of each tank can be set to automatically control the amount of water added, so as to avoid the waste of water caused by negligence when cleaning the tank.
Conclusion This transformation mainly uses Intouch's easy-to-use, powerful conditional script or data value change script and linked action script to generate various alarm information, such as pop-up alarm window or voice prompt; and convenient to put various data through Intouch Write to the database. Through this transformation, the functions of the system are greatly enriched, and the system has higher performance and stability. Due to the high cost of spices, this transformation is also beneficial to the economic benefits.
