A fuel cell system includes a cell stack, a temperature sensor which detects a temperature of the cell stack, an outside air temperature sensor which detects an outside air temperature, and a CPU which controls a process in the fuel cell system. When the temperature of the cell stack is lower than a predetermined temperature, the fuel cell system performs a temperature raising operation of the cell stack by making the concentration of aqueous methanol solution in an aqueous solution tank higher than in a normal operation and by making an output of an aqueous solution pump greater than in the normal operation. The CPU sets a run time for the temperature raising operation based on a detection result from the outside air temperature sensor, a detection result from the temperature sensor, and a run time setting table which is stored in a memory. The fuel cell system is capable of raising a temperature of the fuel cell quickly and stably to the predetermined temperature.

The invention discloses a method and an apparatus for controlling spinning yarn breakage. When a fan starts, a ring rail moves to the spinning starting line and continuously moves upwards; when the ring rail moves to the spinning line, the main motor starts running at a low speed, and the ring rail moves downwards from the spinning line to the starting spinning line, and then spins at the low speed. When the running time is equal to Pd, a position sensor sends signal for spinning in the middle. The ring rail moves upwards to the spinning line and then moves downwards to the starting spinning line, and then balloons are opened timely, so that the balloon wavelength is shortened, the yarn tension is reduced, and the spinning yarn breakage is dramatically reduced. The running time of the ring rail motor can also be set to 5 seconds from the beginning of the fan start, and if the starting spinning position sensor is out of order, the ring rail motor moves upwards and stops in five seconds.

The invention discloses a method and device for simulating natural wind. The method circularly executes the following steps: at least one first rotating speed datum is red at random from a preset normally-distributed rotating speed database, and corresponding running time of each first rotating speed datum through the preset algorithm is determined; according to the at least one first rotating speed datum and the corresponding running time of each first rotating speed datum, a motor is arranged, and the motor can run according to set rotating speed value and the running time; when the technical scheme is periodically executed, the first rotating speed data meeting normal distribution are red continuously at random, on the basis of the rotating speed value, the motor is arranged, and drives a fan to generate the wind speed meeting the normal distribution, the running time corresponding to each rotating speed is kept, and therefore the natural wind can be simulated as much as possible, and the use experience of a user is improved.

The control method is characterized by comprising a starting step, a step for spinning small yarns, a step for spinning medium yarns, a step for spinning large yarns, a yarn feeding step and a high-speed halfway stopping step. When a fan is started, a ring plate moves upwards to an initial spinning position and moves upwards continuously; the ring plate moves upwards to an appropriate spinning position; a main motor is operated at a low speed; the ring plate moves downwards to the initial spinning position from the appropriate spinning position; the spinning is carried out at a low speed; if the operating time is equal to Pd, the step for spinning the medium yarns is started; the ring plate moves upwards to the appropriate spinning position first and then moves downwards to the initial spinning position; an air ring can be opened in time; the wavelength of the air ring is shortened; the tension of the yarn is reduced, and the broken end rate of yarns when the small yarns are spun can be greatly reduced; in order to protect the ring plate motor, the operating time of the ring plate motor can be set to start five seconds later after the fan is started, and if an initial spinning position sensor is in malfunction, the ring plate motor can be stopped when moving upwards for five seconds at most.

Reduces energy consumption by running hands only when needed. By pressing down the mode changeover switch, the second hand can be selectively moved to the position of the pointer running start time setting mode (wake-up), the position of the pointer running stop time setting mode (sleep) and the position of the alarm time setting mode (alarm) . With the second hand at each setting mode position, set the hour / minute hand to the desired time by pressing the time setting switch, thereby setting the hand stop time, hand start time, and alarm time. When the pointer operation stop time is reached, the operation of the pointer is stopped, and when the pointer operation start time is reached, the time pointer is rapidly advanced to the normal time, and then the normal time display is performed. In the case that the pointer operation stops, within a predetermined period of time before the alarm time is reached, the pointer operates in a manner similar to the above, returning to a normal operating state, and then an alarm is generated when the alarm time is reached.
