The invention relates to a monitoring data storing method in a central monitoring management system, which comprises: determining a variational threshold value, a minimum period and a maximal period based on physical characteristics of monitoring data; comparing a ''current collected value'' with a ''latest collected value'', judging whether the change amplitude exceeds the variational threshold value; and finally judging whether reaching the maximal period and the minimum period, so as to select the monitoring data to be stored. In the invention, with reasonable storage period and threshold value setting, the storage of real-time circulated data amount is reduced under huge data storage amount, thereby a high-efficiency data storage effect is realized.

The invention provides a refrigerator temperature control method based on food materials and a computer storage medium. The refrigerator temperature control method based on the food materials includes the steps that the weight of put food materials and the maximum weight of raw food materials in a storage chamber of the food materials are obtained; whether the weight of the put food materials is higher than the maximum weight of the raw food materials in the storage chamber of the put food materials or not is judged; if the weight of the put food materials is higher than the maximum weight of the raw food materials in the storage chamber of the put food materials, the target temperature of the storage chamber of the put food materials is determined according to the best storage temperature of the put food materials and the current target temperature of the storage chamber of the put food materials, and if the weight of the put food materials is not higher than the maximum weight of the raw food materials in the storage chamber of the put food materials, the target temperature of the storage chamber of the put food materials is confirmed to be the obtained current target temperature of the storage chamber of the input food materials; and a refrigerating system is driven to work according to the target temperature. By means of the scheme, the storage effect of the newly-put food materials and the storage effect of the original food materials in the storage chamber can be taken into consideration, and the practical needs of users are met.

The invention relates to a thermoelectric-combined-system distributed scheduling method under an auxiliary service market environment and belongs to the electric power system operation control technology field. In the method, a scheduling model of an electric power system and a scheduling model of a heat supply system are comprehensively considered, and an extra scheduling target under the auxiliary service market environment is also considered so that a thermoelectric-combined-system scheduling model under the auxiliary service market environment is established. Based on a variable direction multiplier algorithm, the electric power system and each heat supply system process scheduling problems of respective jurisdictional areas in a distributed mode. Through interactive iteration of boundary data among different systems, a thermoelectric-combined-system distributed-scheduling optimal solution under the auxiliary service market environment is acquired. By using the thermoelectric-combined-system distributed scheduling method under the auxiliary service market environment, a good convergence speed is possessed; and through a heat storage effect of the heat supply system, flexibility of system operation can be increased.

The invention provides a refrigerator temperature control method based on food materials and a computer storage medium. The refrigerator temperature control method based on the food materials comprises the steps that optimum storage temperature of the food materials put into a refrigerator and current target temperature of a storage compartment where the food materials put into the refrigerator are located are obtained; whether the optimum storage temperature of the food materials put into the refrigerator is lower than the current target temperature of the storage compartment where the food materials put into the refrigerator are located or not is judged; if yes, target temperature of the storage compartment where the food materials put into the refrigerator are located is determined according to the optimum storage temperature of the food materials put into the refrigerator and the current target temperature of the storage compartment where the food materials put into the refrigerator are located, and if not, the target temperature of the storage compartment where the food materials put into the refrigerator are located is determined as the obtained current target temperature of the storage compartment where the food materials put into the refrigerator are located; and a refrigerating system is driven to work according to the target temperature. According to the refrigerator temperature control method based on the food materials and the computer storage medium, the storage effect of the food materials which are newly put into the storage compartment of the refrigerator and the storage effect of the original food materials are both considered, and the actual requirement of a user is met.

The invention provides a super-junction IGBT (Insulated Gate Bipolar Transistor) device. Forbidden bands of semiconductor materials of emitter regions are wider than other semiconductor regions; and base regions and emitters are connected through a diode or two diodes which are connected in series along the same direction or more diodes which are connected in series along the same direction. Forward switch-on voltages of diode accesses between the base regions and the emitters are smaller than the forward switch-on voltages of hetero-junctions formed in the emitter regions. When forward switch-on is carried out, the diodes between the base regions and the emitters are switched on, potentials of the base regions are raised and few carriers injected from collector regions to voltage resistant regions are prevented from being collected, so the storage effect for the carriers in the voltage resistant regions is improved. Compared with a traditional super-junction IGBT, the super-junction IGBT provided by the invention has the advantage of obtaining lower switch-on voltage reduction.

The invention discloses a foam heat storage regenerator and a preparation method thereof. The existing heat storage regenerators are all of direct type network structures or honeycomb structures, thereby having small surface area and non-ideal thermal storage effect, besides, due to the limitation of product forming, the shape of products cannot be too large, which has a higher requirement to application environment, therefore, the existing heat storage regenerators generally have the disadvantages of large difficulty of processing, high cost, low yield and narrow application range. The invention takes kaolin, aluminum oxide, spodumene and organic material as raw materials, the raw materials are first coated and adhered by polymer cavernous mode and then burnt and the finished products are produced. The invention has the advantages of large surface area, which is over 2000m2 / m3, good heat storage effect, large application efficiency, which is more than 90 percent, small product water absorption, which is less than 1 percent, high anti-pressure strength, large heat capacity, wide application, no limitation of system waste gas types, long service life, small processing difficulty and low cost and materials can be fully applied and comply with the environmental protection requirements.
