Control and Monitoring System in Garment Section

Application part is the interface between master controller and receiver controller with a computer. It is software which saves routine data of machines in a text or excel file. Excel File will contain all machines start time and working hours in a day. One sheet of excel file will contain complete one-month data of nth machines. One excels file will contain twelve months of data. The application software will appear in Quick lunch. Date and time will update through RTC automatically. When the next day comes, curser will move automatically to next tab. Similarly, when next month comes data will save into the next sheet automatically. Communication starts when receiver reply, then master sends the machine data. If the receiver not reply may be its power off or receiver not responding due to some problem that’s why master saves data to memory and when receiver replays then master send it to receiver. Program is running behind the front-end application part. First time applicationneeds to install. After installing application icon appears at Quick launch. Application continually checks the USB terminal and when the data come its save into excel file. Excel file contains the working time of workers. Rows contain worker number and columns contain the worker time. One sheet contains one day working data in excel file. When next day comes data will save into next column. When next month will come, data will into the next sheet of excel file. Data Rate of transmission is slow, it can increase using high baud rate transmitter and receiver. Application part is compatible for windows XP. It can be improved for other windows and operating systems

CURRENT SENSING MECHANISM USING MICRO CONTROLLER Microcontroller is a mandatory requirement because we are using MAX RS485 for master slave purpose; wireless regenerative transmitter and receiver as well as data also need to save. All those reasons, we shifted towards the microcontroller. Moreover, our circuit area is also reduced. We can use delay using microcontroller which is more reliable.A.Slave Working Main supply to comparator circuit is same which elaborate above. Comparator output goes to microcontroller pin. Controller continually checks the P0.4 pin. When the output of the comparator will high, then the controller will give signal to P1.6 pin at the base of the transistor 2222 switch. Transistor gives the signal to 5V relay and relay will turn on the light. When the lights turn ON, it means worker start working and starting status is sent to master using MAX485. Whenever the machine turns off, the output of comparator gets low. But controller continually gives a signal to relay according to delay. Delay is adjusted according to desire. When delay finishes, the controller checks the status of the machine and if the machine still not operating then relay signal get low and light will turn off. When the lights turn off then controller again send a signal towards master using RS485.Master Working Master requests the machine status from slaves after every adjustable time. Slaves send its status to respective master through serial communication MAX485. Master saves machine status and its time using RTC (DS307). Then every master sends data towards the single master on the requested time. Single master sends data to receiver end using R.F (super regenerative module) transmitter and receiver, Data receives through R.F receiver and send data to computer through USB terminal and saves data to excel sheet. If single master didn’t respond then master save data into its memory then transmit upon ask, similarly, if the receiver doesn’t respond, then the master will save data into its memory.

After getting results, now the complete sewing machine hall station lights and optional fan will automatically turn ON when machine starts. When workers are not working according to settable time, then lights will turn off automatically. Master will save the working time of the machine. Master sends the machine working time to the receiver then the receiver sends it to the computer through RS232 USB terminal, application program running there. Data will save automatically to excel sheet. Authors like to thank the competitive authority of Master Textile Industries Pvt. Limited for its corporation as it allows the working and building the system for the sewing machines. Special thanks to Head of Sewing Machine Department and Senior Faculty Members of the Electrical Engineering Department who guide throughout this process .https://www.vssewingmachine.in/
