Purple light FPGA solves the mask problem! Boost the overall speed-up of mask production

With the domestic COVID-19 gradually under control , All walks of life are returning to work in an orderly manner , The demand for masks has soared , In recent days, , Ziguang Tongchuang jointly launched " built-in 2 Nuclear processor FPGA" Architecture , It can effectively improve the production capacity of mask machine , And ensure quality while improving production efficiency , Greatly save wiring and troubleshooting time , Save time , Meet the sharply increased demand for masks during the epidemic .

According to the report of prospective industry Research Institute , At present, if the full resumption of production , Per person per day 1 Only mask calculation , At least every day 5.3 Million masks , At home 2019 The maximum annual production capacity of masks is 2000 Ten thousand only / God , Unable to meet , In addition, it is difficult to resume work due to the epidemic , The production capacity of each link of the mask machine industry chain is extremely short , It seriously restricts the timely supply of masks , Many enterprises have switched to masks , To meet the needs . Semiconductor enterprises are also actively taking responsibility , Make breakthroughs and innovations in their respective fields , Join the ranks of solving the production problem of masks , Ziguang Tongchuang has made great efforts , It took the lead in launching a technical solution that can effectively improve the production capacity of the mask machine .

At present, the masks on the market mainly include medical surgical masks and N95 masks , There are some differences in production process , From the principle point of view , It's all about using PLC、 Servo motor and other program control realize automatic production , As the production of masks involves tension control 、 Slitting compound 、 Cutting 、 forming 、 welding 、 Vertical packaging and other processes , Therefore, the production equipment control system is required to have high response 、 High speed communication 、 High precision and high synchronization , To meet the high-speed and stable production demand of mask machine .

In order to ensure the high-speed operation of the mask machine , Ziguang Tongchuang jointly launched " built-in 2 Nuclear processor FPGA" Architecture , The scheme has IEC61131 Standard and external communication processing engine , Real time motion control drive engine 、 High speed synchronous communication engine between modules , It USES the EMMC SD USB3.0 DDR3 Speed up memory , built-in 32 Highway IO（16in/16out）, In order to realize the PAC High speed communication of operation controller . In the scheme , Purple light co creation Compact Series low power consumption CPLD Play a IO The key role of expansion , The communication speed and synchronization accuracy of each instruction are greatly improved .

besides , Want to achieve maximum productivity , It is also necessary to carry out multi axis high-speed synchronous control of the servo motor of the mask machine . Compared with the traditional pulse scheme , be based on EtherCAT High speed Ethernet scheme based on , Multi axis synchronous control , In addition to increasing the production quantity of masks per minute , It also has high response positioning characteristics , It can greatly improve the precision of mask cutting and double ear belt welding , Ensure quality while improving production efficiency . Besides , Use all EtherCAT Multi axis connection , It can also greatly save wiring and troubleshooting time , Save time , Meet the demand for large-area masks during the epidemic .

Based on Ziguang Tongchuang FPGA Of EtherCAT Communication scheme , Have an accurate master station DC, The synchronous output of the slave station reaches 40 Nanosecond synchronization accuracy , More prominent EtherCAT Synchronization performance and efficiency of Fieldbus , Greatly reduce the burden of the processor .

It is reported that , At present, enterprises in the industrial control industry are actively evaluating the scheme , This scheme will soon be used in the automatic mask machine . Ziguang Tongchuang said , It will cooperate with the upstream and downstream of the industrial chain , Coordinate a large number of R & D and technical resources , With the help of FPGA Flexible and customizable features of chip products , Fully support customers to optimize product solutions , Provide efficient detection for epidemic prevention and control 、 distinguish 、 Analysis and protection support .
