The invention relates to the field of kitchen appliances, and discloses a food heating control method, food heating control equipment, and a cooking utensil with the food heating control equipment. The food heating control method comprises the following steps: detecting a temperature change rate curve of a heated food along with the heating time; comparing the temperature change rate curve with a preset temperature change rate curve; and judging whether to stop heating `the food or not according to the comparison result. According to the food heating control method, when a temperature sensor has certain error, the operation of cooking equipment can be controlled accurately, and the cooking effect is guaranteed.

The present invention belongs to the technical field of intelligent control system and relates to a function elevator control method and a system with a video monitoring device. The existing elevator control system usually relies on weight information to determine whether the elevator is full, when the elevator is filled with an object with large size and light weight, even if the elevator space is filled fully, the elevator control system cannot determine the elevator is full because of light weight and continues to stop on unnecessary floor so that elevator operation efficiency is reduced and elevator operation cost is increased. The system provided by the present invention can gain real-time image with the video monitoring device and compare the real-time image with empty elevator image shot previously so that when the system finds out that most part of the image is different from the empty elevator image, the elevator can be determined to be full. With load and space service condition of the elevator, the present invention can control the elevator more efficiently and improve operation efficiency of the elevator.

The invention relates to an intelligent sleeping air conditioner control method and an intelligent wearable device and system. The method includes the following steps that S1, the wearable device detects sleeping data of human bodies in the air-conditioner season to obtain a sleeping data detecting value; S2, the wearable device compares the sleeping data detecting value with a sleeping data reference value of human bodies in the non-air-conditioner season to obtain a comparison result and sends a control instruction to an air conditioner according to the comparison result; S3, the air conditioner runs according to the control instruction. The sleeping data detecting value, collected by the wearable device, of the human bodies is compared with the preset sleeping data reference value, the wearable device can regulate and control the running state of the air conditioner according to the sleeping states of human bodies in different seasons, and people can be effectively prevented from influenza and other unwell symptoms when sleeping in the air-conditioner season.

The invention discloses an energy-saving heat pump humidity removing drying room and a control method of the drying room. The drying room comprises a room body, a heat pump assembly, a circulating fan assembly, a humidity removing assembly, a main control unit and a temperature and humidity sensor, wherein the humidity removing assembly comprises a heat exchanger, an air inlet fan and a humidity removing fan, and the air inlet fan and the humidity removing fan are respectively connected with an air regulator. When humidity removal is performed in the drying room, external air is turned into dry cold air through a heat pump host, the dry cold air enters the heat exchanger and is conveyed back into the room body after having non-direct-contact heat exchange with high-temperature and high-humidity air pumped out of the room body, and therefore energy is saved. The actual measured temperature and the actual measured humidity are compared with preset stage values, particularly, the preset stage values are divided into preset values in a shutting down stage and preset values in a starting stage, the starting stage is subdivided into a plurality of segments, firstly, the stage or the segment where the actual measured humidity is located is judged through the current humidity, then, according to the current temperature, the actual measured temperature is compared with the set temperature value in the stage or the segment, the humidity removing assembly is controlled to operate at low speed or to operate at full speed or to shut down, and therefore drying efficiency is improved, and energy consumption is reduced.

Provided are a Stirling engine and a control unit used therein. The purging unit and the power cylinder can be arranged separately from each other, thereby increasing the degree of freedom in the layout of the Stirling engine. In the case of a separate arrangement of the purging unit and the power cylinder unit, the purging unit compression chamber is connected to the operating chamber of the power unit via a pressure line. A control actuator connected to the purge piston enables the arbitrarily controlled purge piston of the purge unit.

The invention relates to a method and a device for controlling an air conditioner and a server. The method comprises the following steps: acquiring sleep state information of a user; determining control parameters of the air conditioner according to the sleep state information; controlling the air conditioner to run according to the control parameters. According to the method, the air conditioner is controlled to run according to the sleep state information of the user, so that the problems that the air conditioner continuously runs based on the control parameters preset by the user after the user enters the sleeping state, such as large wind speed, low temperature and wind facing the user which lead to cold of the user, can be solved.

The invention discloses an air conditioner control method which comprises the following steps of enabling a fingerprint collecting device set by a controller to be started to collect fingerprint information of a user when the user starts an air conditioner by means of the controller; determining a control parameter for controlling the air conditioner by applying a stored historical record of the air conditioner controlled by the user; and sending the determined control parameter to the air conditioner to control the air conditioner to operate. The invention also discloses an air conditioner control device and system and a computer readable storage medium. By means of the air conditioner control method, device and system and the computer readable storage medium, operation of the air conditioner can be controlled accurately and reasonably, and the comfort of the air conditioner is improved.

The invention discloses a compressor exhaust gas temperature frequency limit control method, an air conditioner and a readable storage medium. In the compressor frequency rising process, the limited frequency is dynamically adjusted according to exhaust gas temperature; if the exhaust gas temperature reaches a first temperature threshold value in the current frequency rising process, new limited frequency is generated, the new limited frequency needs to be lower than the limited frequency of the current frequency rising, and thus the situation that the frequency of a compressor rises to the limited frequency of last frequency rising during next frequency rising, and consequently a frequency reducing temperature threshold value is triggered again is avoided; and therefore frequent limited frequency fluctuations caused by the cyclical fluctuation of the exhaust gas temperature are reduced, system fluctuations are reduced, and the reliability of air conditioning system operation is improved.
