Realizing Industry 4.0 requires a high degree of industrialization and automation, and it is a long journey. Regardless of the extent to which smart manufacturing is developed, data collection is the most practical and high-frequency requirement in production and a prerequisite for Industry 4.0. The collection and management of industrial data plays a significant role in improving machine efficiency.
Option 1: Internet of Things Industrial Field Data Acquisition System
This project belongs to the sensor system of the Internet of Things terminal. It collects the working information of the PLC of the specified machine through the wireless module installed on the machine, uploads it to the host, and the host processes the data and uploads it to the cloud server. The user can be on the mobile phone, tablet or computer. View machine work information and set machine operating parameters to a limited extent.
Option 2: Data acquisition module for solar charging
The bottom slot of the finished product can be embedded in the industrial standard din35 guide rail for easy installation; it has two digital inputs, two analog inputs and eight IO outputs. The solution also adopts the solar charging mode, integrated GPRS module, and can be automatically reset after disconnection, to avoid the problem that the external external DTU needs to send SMS after the offline is disconnected.
Solution 3: U disk data transfer, paperless recorder solution
The paperless recorder is a new paperless recorder that uses the latest U disk data storage and data dump technology. According to user requirements, its data storage capacity can be configured up to 32G, which can meet the data storage requirements of any industrial site. In particular, the data retrieval method recorded by the U disk is superior to other methods such as an IC card, and has the advantages of large data storage capacity, convenient and reliable use, and is suitable for actual use on site.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
In addition to SCSI, IDE is also a very common interface. From the point of view of ease of use, IDE is more suitable for ordinary users. In addition, personal computer users not only need to configure a few peripherals, but also do not require high speed. Therefore, it is more appropriate to choose IDE interface. In addition, IDE also has the characteristics of high performance price ratio and wide application. Although the SCSI interface has many incomparable characteristics, the price of the interface and its peripherals is too expensive to be borne by ordinary users, which determines the limitation of its actual use range.
1. The working mode of IDE requires the whole process participation of CPU. When the CPU reads and writes data, it can't perform other operations. In this case, in the multitask operating system of Windows 95 / NT, the system reaction will be greatly slowed down. The SCSI interface controls the data reading and writing operation completely through the independent high-speed SCSI card, so the CPU does not have to waste time to wait, which obviously can improve the overall performance of the system. However, IDE interface has also made great improvements to improve this problem. DMA mode can be used instead of PIO mode to read and write data. DMA channel is responsible for data exchange, which greatly reduces the CPU consumption. However, comparing the CPU utilization of SCSI and IDE, we can find that SCSI still has considerable advantages.
2. The scalability of SCSI is larger than that of IDE. Generally, each ide system can have two IDE channels, with a total of four IDE devices. The SCSI interface can connect 7-15 devices, much more than IDE, and the cable connected is far longer than ide.
3. Although the price of SCSI device is higher, compared with IDE, the performance of SCSI is more stable, durable and reliable.
