Portable SOE system checking device

Abstract

The invention discloses a portable SOE system checking device. The portable SOE system checking device comprises a core control unit, an output unit, a communication unit, a display unit, a button operation unit, and a storage battery power supply unit. The output unit comprises an output control circuit and an output safety circuit. The output control circuit is connected with the corresponding port of the core control unit by the output safety circuit, and the communication unit and the button operation unit are respectively in a bidirectional connection with the corresponding port of the core control unit. The output end of the core control unit is connected with the input end of the display unit, and the power supply end of the storage battery power supply unit is connected with the power supply end of the display unit, the power supply end of the button operation unit, the power supply end of the output unit, the power supply end of the communication unit, and the power supply end of the core control unit. The portable SOE system checking device is advantageous in that the checking effect of the SOE system is guaranteed, and at the same time, the investment cost of the checking device is reduced; no external power supply is required, and workload of connection with a power line is saved, and working difficulty is reduced.

Description

technical field [0001] The invention belongs to the field of thermal automation measurement and control, and relates to a portable SOE system calibration instrument, in particular to a portable SOE event sequence recording system calibration instrument. Background technique [0002] The SOE system is a subsystem used for abnormal records in various automatic control systems. It records the event occurrence time, the first event and the interval sequence of chain events, which are the most important basis for system failure and abnormal analysis. As such an important subsystem, it is very necessary to verify the accuracy of SOE records during system maintenance. The traditional SOE system calibration instrument is bulky and heavy, while the SOE system is usually located in the high-level equipment electronics room, and the heavy instrument is very inconvenient to carry; the wiring is complicated and inflexible, and only continuous trigger channels can be selected; 220V is re...

Problems solved by technology

The traditional SOE system calibration instrument is bulky and heavy, while the SOE system is usually located in the high-level equipment electronics room, and the heavy instrument is very inconvenient to carry; the wiring is complicated and inflexible, and only continuous trigger channels can be selected; 220V is required The AC power supply can only work. There is often no 220V AC power supply near the SOE system, and it needs to lead from other power interfaces, which increases the difficulty of the work of the calibration personnel, reduces the work efficiency, and causes great inconvenience to the on-site calibration work.
