Position:(9) electric power monitoring
Power supervisory system changes to channel the moving condition of electric place and box type transformer substation undertakes monitoring, the parameter such as temperature of element of power of the working condition that basically monitors ark of tall, low-pressure switch, switch condition of each breaker, breakdown, electric current, voltage, frequency, have rendered great service, power, transformer, undertake monitoring to offerring distribution system equipment and return of ventilated, illume, implementation shows, call the police, statistic, safeguard wait for a function.
(10) channel fire alarm
Cent of fire alarm means is moved for the hand call the police pushbutton and fire are automatic detector two kinds.
The hand is moved call the police pushbutton, move by hands of every 50 meters of a setting inside channel call the police pushbutton. Fall in emergency by press artificially move call the police pushbutton, send signal channel monitoring center.
Automatic fire alarm is explored can use distributed fiber-optic sense lukewarm automatic detector, inside channel coping lays feeling lukewarm fire explores cable, successive to undertaking inside channel temperature detects. Fine of consumed of this system interest regards linear feeling as lukewarm detector, this detector is based on fiber-optic and backward play graceful scattering effect, produce a longer than illuminant wavelengh light, weigh Situokesi (Stokes) is smooth, grow short light than illuminant wave with, the Situokesi after calling (Anti-stokes) is smooth, fiber-optic the modulation that suffers exterior temperature makes fiber-optic turn over Situokesi mediumly (Anti-stokes) light intensity produces change, the ratio of Anti-stokes and Stokes provided the absolutely instruction of temperature, those who use this one principle to be able to realize pair of fiber-optic temperature field is distributed measure, accordingly, it is fiber-optic and OK to feel lukewarm show environmental temperature with successive linear means. Should explore the exact position that the system locates temperature happening changes well and truly, fixed position accuracy can amount to 10cm.
Fire alarm system accepts channel inside, change the alarm signal that electric place, pump room and equipment use the fire detector inside the room, when fire produces inside channel, issue alarm signal, issue sound, smooth alarm signal, show the specific place of fire alarm, show accident location automatically through video supervisory system go up in corresponding workstation and big screen, start corresponding control beforehand case, if start the establishment such as put out a fire of lash-up illume, ventilated, fire control, release liaison man revulsive information, attemper breakdown lorry and personnel, so that the car inside channel of dredge of can fast, orderly ground is mixed personnel, safeguard channel and department take the life property security of personnel.
