Introduction of DORLAND Industrial Explosion-proof Handheld Terminal, Ex PDAs

PDA handheld terminal integrates barcode scanning, RFID reading and writing, fingerprint recognition, face recognition and other functions, especially the RFID reading and writing function is widely used. Let us briefly understand the working principle of the RFID system structure:

The RFID portable handheld terminal integrates the antenna, the reader, and the host computer. After the RFID tag enters the magnetic field, it receives the radio frequency signal sent by the reader and transmits the product information stored in the chip with the energy obtained by the induced current. Or, the tag actively sends a signal of a certain frequency, the reader reads the information and decodes it, and sends it to the central information system for related data processing.

Let's take a look at the major application scenarios of PDA handheld terminals.

Warehouse management

The PDA handheld terminal is used to make clear database records of the types, quantities, production attributes, stacking positions and other information of the goods in the warehouse, to obtain accurate goods data and supply chain information at each stage of the logistics chain.

Logistics management

By Connecting to the host computer through wireless network, the staff of the receiving department can scan the barcode of the goods with a PDA handheld terminal, confirms the item number, and then enters the quantity of the goods to see whether the goods meet the order requirements.


The PDA handheld terminal can be used to query the patient-related information in the ward, making ward management easier and more agile, and can quickly query the patient's diagnostic records, treatment procedures, and customized ward maintenance.

Production line management

Enterprises can rely on the information system ("one object, one code") established by PDA handheld terminal to improve the management efficiency of production, distribution and warehousing. This helps managers to easily control the real-time production situation of the enterprise and improve the convenience of management.

Cargo inventory

The tally clerk only needs to use the handheld terminal, go to the shelf number according to the instructions, scan the barcode of the designated product, check the product after confirming it, and then upload the information to the background management system in real time through the handheld terminal for data analysis.

In order to help enterprises to create a safe and efficient working environment, DORLAND independently developed and manufactured a special industrial-grade intelligent explosion-proof PDA.

The difference between explosion-proof PDA and ordinary PDA is that, the former has passed the national explosion-proof certification, while the later do not have. Explosion-proof PDA has undergone special explosion-proof treatment. It is designed with explosion-proof batteries and explosion-proof circuits. Explosion-proof PDAs have less current and will not cause an accident even if one circuit node is short-circuited. At the same time, the shell of the explosion-proof handset is made of anti-static, insulating and flame-retardant materials.

DORLAND explosion-proof PDA can be widely used in flammable, explosive, and hazardous chemical environments, such as explosive gas and dust sites in petroleum and petrochemical, natural gas, chemical, smelting, and other industries. On the premise of ensuring the safety of the production environment, it brings great convenience to the realization of applications such as inspection, chemical management, on-site storage and exit management, and on-site material management.
