The invention relates to a device and method for simultaneously monitoring flue gas particles and polluted gases on line. A spectrometer (16) is fixed with a flue (17) via a flange (18), and a flue gas emission parameter measuring unit (14) is fixed with the flue (17) via the other flange (18). The measurement signal of the flue gas emission parameter measuring unit (14) and the measurement signal of the spectrometer are connected to an AD converter (13) through cable conductors and are sent to a computer (15). The method of the invention is the extension of a DOAS method, namely absorbing the rapid change components in the spectrum for online analysis of the polluted gases and absorbing the slow change components in the spectrum for online analysis of the particles after correcting slow change absorption of the polluted gases. The invention solves the technical problem of using the same light path to simultaneously monitor the polluted gases and the particles on line and reduces the system cost. Meanwhile, the probe inlets cut on the flue are lessened, thus the workloads of field installation, debugging and system maintenance in the future can be lightened.

The invention discloses an implementing method of protecting an IEGT (injection enhanced gate transistor) based on a relay protection tripping signal, belonging to the field of control. The implementing method comprises the steps of: introducing a 'tripping' control signal of a breaker into logic trigger conditions of a blocking IEGT triggering pulse module to form a mode of new logic trigger conditions of the blocking IEGT triggering pulse module together with original logic trigger conditions, outputting a 'blocking IEGT triggering pulse' signal through the blocking IEGT triggering pulse module after a microcomputer protection device outputs the 'tripping' control signal, before the 'tripping' mechanical action of the breaker, shielding/blocking the triggering pulse of the IEGT in a frequency convertor so as to turn off the IEGT and avoid the impact on the IEGT caused by a di/dt current mutation value impact, and to protect the IEGT. The protection action mechanism of the implementing method is cleverly set and easily achieved, and according to the protection action mechanism, the needed time of an on-site repair process is shortened greatly, the production can be resumed quickly and the production/maintenance cost can be lowered.
