Abstract
The utility model provides a controller for a motor of a fire preventing rolling shutter door machine, which comprises a standby power source, a power source, a rolling shutter motor and a clutch. The utility model is characterized in that through a power source transforming device, the power source and the standby power source are used for controlling the clutch. When the alarm occurs, or the power source of the rolling shutter machine is out of work, a three-phase power source is probably completely lacked, or the three-phase power source is lack of phases. Thus, the controller can be used for charging up a rapid discharge control device and controlling the rapid discharge control device to generate sufficient pushing (pulling) force or strokes; a braking mechanism (an electromagnetic clutch) of the rolling shutter door machine is started to make a rolling shutter drop depending on the self weight. In addition, the controller can be used for controlling the rolling shutter to stop at the presetting position (namely, the braking mechanism of the rolling shutter door machine is closed.).

When having the condition of a fire to take place, controller is in " condition of a fire is arranged " state, and controller sends sound and light alarm, transmits fire signal to the fire-fighting center.To being used for the roller shutter of fire separation, controller controls roller shutter automatically and descends until cutting out, and prevents that the condition of a fire from stretching.To being used for the roller shutter of fire escape, if a thoughts smoke signal or fire-fighting center signal partly falls, controller is controlled roller shutter decline automatically or is risen to (1.8 ± 0.1 meters apart from ground of predeterminated positions, meta is called for short in this position), when treating the high-fall signal at temperature-sensitive signal or fire-fighting center, controller controls roller shutter automatically and descends until cutting out, and prevents that the condition of a fire from stretching.No matter the fire curtain of which kind of purposes; insert the anxious control that stops at its three manual buttons of all available controller of process " unlatching ", " closing " and " stopping " that descend automatically; when controller is received emergent stop signal; controller is controlled roller shutter automatically and is paused at meta; at preset timed intervals after (30～300 seconds adjustable) time-delay; automatically drop to again and close, suddenly stop or in stop the escape that delay function is used for personnel.
Rolling door body and roller shutter motor are electronic product, and the manufacturing technology maturation is drought, and existing national standard is carried out standard to product, and the control technology of fire curtain then develops hysteresis, and four developing stage are roughly arranged, and the technical characterictic in each stage is as follows.
Phase I: controller all is made of low-voltage electrical apparatus, and the function of controller is few, poor reliability, volume are big, and aforementioned basic function can not all realize.This stage does not have national standard and industry standard.
Second stage: introduce electronic technology, adopt discrete electronic component and a small amount of small scale integration to constitute the controller logic circuit, the function of controller increases to some extent, but reliability and volume still do not have much improvement, and aforementioned basic function can realize substantially.The related product of " 96203754.0 " patent is the product in this stage.This stage does not have national standard and industry standard.
Phase III: introduce microelectric technique, adopt microcontroller chip to constitute the logic circuit of controller, the function of controller improves a lot, product has certain intellectuality, reliability and volume have bigger improvement, if AC power does not have fault, aforementioned basic function can realize all that technology is than the first two stage complexity.Kylin company produces the product that old type fire curtain controller belongs to this stage.This stage does not have national standard and industry standard.
Prior art shown in Figure 1, system architecture is simple, there is not standby electric power, also just there are not a series of problems relevant, are connected the single power supply mode that need not selective system of detection, backup power source voltage sampling, AC power detection of power loss, system power supply with standby electric power, need not to carry out battery maintenance as charging circuit, charger with charging.Do not have fast playing function, the power supply of roller shutter motor and brake coupling thereof needn't separate, thereby does not aim at the device of brake power supply, as electric power conversion apparatus, clutch power supply switch circuit, also need not detect the clutch coil fault.In addition, system intelligent is also lower, can not carry out fault self-checking to fire detector surveys, only to building fire-fighting center feedback fire signal and roller shutter meta signal, five luminous tube indicator lamps are only arranged, be respectively upper limit indication, lower limit indication, condition of a fire indication, three phase mains indicating fault, the indication of control power supply.
Prior art does not have standby electric power and fast releasing apparatus, because fire happens suddenly when giving birth to, often follows the disappearance of AC power, if do not have standby electric power and " speed is put control device ", in case during the AC power disappearance, controller descends uncontrollable roller shutter, does not have the effect that fire prevention is isolated.
