Application of Zijinqiao Configuration Software in Scanning Gun
At present, many industrial products often require an identity during production, testing, and logistics. Through this identification, it is convenient to query relevant test data and inventory location of each link of the product pipeline. Barcodes or QR codes are the identifiers of most products because they are simple, reliable, cheap, and convenient. The barcode can be easily scanned to the barcode or QR code to realize the identification of the product.
Scanners can be divided into handheld, platform, etc. The interface of the scanner can be serial port, parallel port, USB port or PS2 port. In practical applications, projects involving barcodes or scanners usually require the use of a relational database to store relevant bar code content and related parameters of the bar code product. At the same time, it may also involve communication and monitoring of industrial products such as PLC. Zijinqiao configuration software can easily communicate with scanners and PLCs, and can communicate with relational databases conveniently. For the projects that the author has done only, the projects using the configuration software and the scanner are mainly used in the workshop assembly line monitoring, product outbound or inbound logistics. Here is a brief summary of some of the points in the application:
When it is matched with the configuration software, the scanner with the serial port is usually selected. Regardless of whether the scanner is infrared or laser, the scanned data is usually transmitted to the PC through the serial port in the form of ASCII code. Different scanners may add some header or trailer identification at the beginning and end of the data. Generally speaking, communication is relatively simple. However, the communication of most scanners is one-way. Scanning guns send data to the PC. The data sent is rarely verified. The PC only passively receives data, and it is difficult to judge whether the data is correct or not.
Generally involved in the project of the scanner, usually use a relational database to save the bar code content and related parameters of the bar code product. There are two aspects to consider here, one is the amount of data, and the other is the data interval. The so-called data refers to the historical record that needs to be saved. On the assembly line, thousands of records are usually generated every day. These records need to occupy a certain space for storage and query. If the storage time is short and the data is small, you can use it. Access database, simple and cheap. If the amount of data per day is large and the storage time is long, you can use a relational database such as SQL sever or Oracle. However, the prices of the two databases are not low. In actual applications, sometimes multiple Access databases are used or saved every day. A method of discounting text or Excel to achieve an inexpensive preservation of data. Of course, when using the compromise method, data query and other operations are not convenient. In addition to the amount of data, in practical applications, sometimes also concerned about the interval between data. The so-called interval of data means that sometimes several fields of a record may have several update operations in a short period of time, and the data that is updated first may affect the data that is updated later. For example, in a production line, two parameters need to be tested. After the current one passes the test, the latter continues the test. In this case, pay attention to the time interval between the two. Because when accessing a relational database through ODBC or OLEDB, it takes a certain amount of time. This time is usually determined by the relational database itself, and when there is more data, it is necessary to pay attention to the setting of indexes and other aspects to speed up the relational database. operating.
In the project of using the scanner, sometimes linkage control is involved. For example, the barcode is scanned by the scanner, the barcode is saved to the PC, and the PC controls the PLC or other instrument to perform tests on the product. In many cases, there is no direct communication between the scanner itself and the PLC. The PLC cannot judge the barcode of the tested product. At this time, the PLC is notified by the PC, and then the test result is saved in the barcode data. In practice, the operation must be strictly regulated.
The above points are some of the experiences of the author when using the Zijinqiao software and the scanner. The current application of scanning guns in the field of industrial control is increasing. I hope to bring you some help here. Please correct me if you are not correct.
2 What are the wooden handicrafts - wine rack
The shelf for placing various drinks can be made of wood. Such a wooden wine shelf is not only beautiful but also very practical. Generally, the drinks to be displayed are very expensive, and many people store them accordingly. The wood used to make the wine rack should consider what kind of wood is best to choose. In fact, the wood used in general is not ordinary, especially in large shopping malls and high-end clubs. The wood for wine racks is very expensive.
3 What are the wooden handicrafts - jewelry box
Most of the boxes used to place jewelry are made of wood, and some gold jewelry is suitable for wooden jewelry boxes. Jewelry is an accessory worn by women. When not wearing it, it is usually placed in a jewelry box. Which jewelry to choose is also taken out from the inside. It is also important to place jewelry. If the material of the jewelry box is not suitable, it will not have a good maintenance effect. The wooden jewelry box is multi-purpose.
4 What are the wooden handicrafts - root carving
Using the root carving method, the self-generated form and distortion behavior of tree roots are used as the artistic creation objects. Through conception and processing, artistic image works such as characters and animals are created. Root carving artworks can be collected, especially the more precious the wood selected, the more valuable the carved artworks. In fact, the root carvings are rarely artificially modified, and the artworks are more natural and beautiful.
5 What are the wooden handicrafts - screen
A screen is a kind of furniture used in traditional Chinese buildings to block the wind. Screens have a long history and are generally displayed in prominent positions in the interior, which can be used to divide, beautify and block. As an inseparable part of Chinese home decoration, it is a good way to present the beauty of nature and tranquility. The screens used in ancient times are made of wood, and there are exquisite pattern carvings on them, which are of great artistic value.
