Computer Key Device-Safety Management and Control-Unitech-Industrial Security and Intelligence Solutions Provider

Computer Key Device

In the microcomputer anti-misoperation interlock system, the computer key device acts as the core handheld terminal connecting the main unit with field equipment, undertaking critical execution functions. Its main role is to receive operation tickets issued by the intelligent anti-misoperation main unit and strictly perform operations on various on-site locks according to the ticket, thereby preventing misoperation risks at the source. The Unitech computer key device integrates intelligent voice playback, speech recognition, and fingerprint identification technologies, achieving advanced functions such as intelligent voice ticket-reading, voice prompts, and multi-level authorization. The product has been comprehensively upgraded in performance, functionality, and quality, better meeting user demands in real-world applications.
