How much do you know about data collectors?
First of all, we need to understand what is a portable data collector. According to the different uses of data collectors, they can be broadly divided into two categories: online data collectors and portable data collectors. Online data collectors can be divided into desktop and wired data collectors, most of which are directly powered by AC power.
First, we need to understand what is a portable data collector.
According to the different uses of data collectors, they can be broadly divided into two categories: online data collectors and portable data collectors.
Online data collectors
Online data collectors can also be divided into desktop and wired, most of them are directly powered by AC power supply, generally non-independent use, and the data is transmitted by cable connection between the collector and the computer, which cannot be used offline.
There are two general ways to transmit data from this scanner to the computer: one is keyboard emulation; the other is to transmit data to the computer through the communication port. For the former, no separate power supply is required, and the power is drawn from the computer internally; the latter requires a separate power supply.
Therefore, the online data collector must be installed in a fixed position and the barcode symbol needs to be taken to the scanner for reading. At present, some logistics enterprises have started to use it in the inlet and outlet management. Due to some limitations in the scope and usage of online data collector, it cannot be applied to the occasions that need to be used offline, such as inventory counting, scanning of large items and so on. In order to make up for the shortcomings of online data collectors, portable data collectors have come into being.
Portable Data Collector
Portable data collector is designed to adapt to some on-site data collection and scanning of barcode symbols of bulky objects, and is suitable for offline use. When reading, contrary to online data collector, it brings the scanner to scan in front of the barcode symbols, therefore, it is also called handheld terminal and inventory machine.
It is battery-powered and does not communicate with the computer at the same time as scanning. It has its own internal storage for a certain amount of data, which can be transferred to the computer at the right time. Almost all portable data collectors have certain programming capabilities, and with the application programs they can become highly functional specialized equipment, which can meet the needs of different applications.
More and more logistics enterprises are turning their attention to portable data collectors, and some domestic logistics enterprises have already used portable data collectors for warehouse management, transportation management and item implementation tracking.
1 Scope of application
Users should choose different portable data collectors according to their different situations.
If users apply portable data collectors in relatively large, three-dimensional warehouses, we should choose collectors with large scanning depth of field, long reading distance and high first reading rate due to the high storage position of some items and far from the operator.
For users of small and medium-sized warehouses, the requirements in this area are not very high, so they can choose some collectors that are fully functional and easy to operate.
For users to purchase portable data collectors, the most important point when choosing is "enough", that is, to buy the one applicable to their own needs, rather than blindly buying expensive and highly functional collection systems.
2 Decoding range
The decoding range is an important indicator for choosing a portable data collector.
Each user has its own range of barcode code system, and most portable data collectors can recognize several or even a dozen different code systems such as EAN codes and UPC codes, but there are great differences.
In logistics enterprise applications, EAN128 code, Sanjiu code, Cudeba code, etc. are also considered. Therefore, users should take into full consideration the range of codes in their actual applications when purchasing to select the right collector.
3 Interface requirements
The interface capability of the collector is another important indicator for evaluating its function, and is also a key consideration when choosing a collector.
When purchasing, users should first clarify the operating environment and interface mode of their original system, and then choose a portable data collector that adapts to that operating environment and interface mode.
4 Requirements for the first reading rate
The first reading rate is a comprehensive index of the data collector, which is related to the printing quality of the barcode symbol, the design of the decoder and the performance of the scanner.
The higher the first reading rate, the more time saving, but accordingly, the price is also higher than other portable data collectors. During the inventory (stocktaking) of items, the barcode symbols can be manually controlled to be repeatedly scanned with portable data collectors.
Therefore, the requirement of first reading rate is not strict, it is just a measure of work efficiency. However, in the automatic sorting system, the requirement for the first read rate is very high.
Of course, the higher the first read rate of portable data collector will inevitably lead to the increase of its BER, so users should purchase a collector that meets the system requirements according to their actual situation and economic ability when choosing a collector, and balance between the first read rate and BER.
With the general promotion of barcode technology, the rapid development of modernization, the level of electronic business management has been greatly improved, and the market for portable data collectors has been formed and has greater demand.
In fact, the application of data collection system can not only save time, reduce workload, reduce management costs and effectively improve inventory structure, but also establish data collection system in logistics enterprises and use portable data collectors is very feasible.
1 Less difficult to implement
Logistics enterprises only need to purchase portable data collection systems on the basis of the original MIS system, without making a big effort.
With the development of science and technology, the functions of portable data collectors are becoming more and more perfect, and the general system comes with application software so that users can connect with the original system, which will not make the operation of the enterprise and the operation of the original system produce loopholes.
It can be said that the use of portable data collectors is a useful supplement to the original system in terms of inventory (stocktaking).
2 Easy installation, simple operation and applicability of the equipment
It does not need to increase the site, and is not limited by time and space, and is flexible and practical, which is convenient to realize the inventory (inventory) and item tracking management in time.
3 Equipment investment is not high, but achieve significant results
For example, it improves work efficiency, saves working time, reduces manual workload, reduces various management costs, and improves inventory structure in time.
The most important thing is that the use of portable data collectors can shorten the inventory cycle and the time used for each inventory, truly realize the non-stop inventory, and reduce the errors of on-site management to a minimum level.
4 Management, the development of technology is more mature
At present, there are many successful examples in China and abroad that can be learned from. All kinds of portable data collection system application software on the market is practical, easy to operate, good stability, effectively improve the accuracy of inventory data, the reliability of data communication, solve the drawbacks of the slow speed of manual inventory, prone to error.
5 constantly to miniaturization, intelligent, multi-functional development
After the enterprise purchases the equipment, the operator can master the use quickly, without special training or hiring professionals in this area.
With the promotion of barcode technology, the proportion of general merchandise using barcode increases year by year, and the application of logistics barcode becomes more and more extensive, all of which provides sufficient data sources for logistics enterprises to ensure the smooth use of portable data collection system.
