The invention discloses a portable plant station accident linkage alarm system which comprises a housing and an accident linkage alarm circuit. The accident linkage alarm circuit comprises a controller, a DC-DC power supply circuit, a switching value detecting circuit, an Ethernet communication circuit, an alarm circuit, an LED display screen and a watchdog circuit. The switching value detecting circuit, the Ethernet communication circuit, the alarm circuit, the LED display screen and the watchdog circuit are all connected with the controller. The DC-DC power supply circuit supplies power to each circuit. The plant station accident linkage alarm system based on signal acquisition and logic control circuits is achieved. It can be guaranteed that maintaining personnel can be rapidly informed of the current running state of a plant station in emergency. The power supply maintaining safety can be thus effectively improved. The personal safety of on-site workers and the power supply reliability can be further guaranteed.
