A hard disk recorder (HDR) is a system that uses a high-capacity hard disk to record digital audio or digital video. Hard disk recording systems represent an alternative to reel-to-reel audio tape recording and video tape recorders, and provide editing capabilities unavailable to tape recorders. Audio HDR systems, which can be standalone or computer-based, typically include provisions for digital mixing and processing of the audio signal.

A water leakage intelligent protection and image flame monitoring integrated device for a plasma ignition system
This invention discloses an integrated device for intelligent water leakage protection and image flame monitoring in a plasma ignition system, relating to the field of plasma ignition safety monitoring in thermal power boilers. The device consists of a PLC intelligent water leakage protection module, a plasma generator group, a high-definition image flame probe group, a multi-channel hard disk recorder, and a wall temperature monitoring system. The PLC collects the cooling water inlet and outlet pressure, flow rate, and arc current and voltage of each corner of the plasma generator. A two-level algorithm identifies cathode leakage and anode burnout, cutting off the arc power supply and closing the cooling water valve at the faulty corner within 3 seconds, while maintaining operation in the remaining corners. The high-definition probes are equipped with independent cooling air circuits, and the video signals are centrally recorded and displayed. Wall temperature monitoring uses TCK-type thermocouples with an over-temperature alarm threshold of 400℃. All signals are integrated into a DCS system. This invention integrates water leakage protection, flame image monitoring, and wall temperature monitoring into one unit, improving the comprehensiveness and response speed of plasma ignition safety monitoring.
