Multi-working mode double screen notebook computer system and operating control method

The invention relates to a multi-working mode double screen notebook computer system and a method for operating and controlling the system. The system consists of a host, a first display screen and a second display screen. The notebook computer system has two full-specification display screens, and at least the second display screen is a touch screen. When the system is operated and controlled, a detection control unit controls the system to automatically work in multiple working modes such as single screen, double screen, panel computer and the like, and in standard or energy-saving states according to opening conditions of a first switch and a second switch and a power using condition. When the system is in the working mode of the panel computer, screen display signals output by a double-path display unit are reverse screen display signals. The multi-working mode double screen notebook computer system has the advantages of not only providing the two full-specification display screens to obtain larger display screen visual area, but also having the multiple working modes such as the single screen, the double screen, the panel computer and the like and the standard or energy-saving state so as to bring convenience to users for operation and use in various environments with different using requirements.

Method for detecting four-way valve of air-conditioner

The invention relates to air-conditioner intelligent detection technique, and discloses a method for detecting a four-way valve of an air-conditioner. The method for detecting the four-way valve of the air-conditioner can automatically detect and judge whether the four-way valve is normal or abnormal, and timely displays faults, so that convenience is provided for failure predication and after-sales repair. The method comprises the following steps: judging a work pattern when the air-conditioner is switched on; timing operation time of the air-conditioner when the air-conditioner is operated in a heating or a cooling mode; collecting present working frequency of a compressor when the operation time achieves a preset time threshold value; detecting and calculating a difference value of indoor environment temperature and indoor heat exchanger coil pipe temperature and a difference value of outdoor heat exchanger coil pipe temperature and outer environment temperature according to a specific working mode of the air-conditioner when the present working frequency of the compressor achieves a preset frequency threshold value; and judging the four-way valve is abnormal when setting conditions are met, and carrying out alarm reminding for the failure. The method for detecting the four-way valve of the air-conditioner is suitable for being used for intelligently detecting failure of the four-way valve of the air-conditioner.

Method for evaluating simulation imaging of multi-mode synthetic aperture radar

The invention discloses a method for evaluating the simulation imaging of a multi-mode SAR (Synthetic Aperture Radar), which mainly solves the problems of poor adaptability to different operating modes, complex experiment process and long experiment time in the prior art. The method comprises the following steps of: firstly, selecting an operating mode, inputting the parameters of a radar and the motion parameters of a carrier, loading a simulation scene and setting coordinates; secondly, setting a simulation radar echo signal according to a system environment; thirdly, imaging the radar echo signal to obtain a slant-range image; fourthly, geometrically correcting the slant-range image by using a three-dimensional geometric correction method to obtain a ground-range image; and finally, evaluating the quality of the ground-range image, and feeding back and correcting system parameters according the evaluation results so as to provide a feasible basis for a latter semi-physical simulation experiment. The method is applicable to three operating modes including a side looking mode, a slant looking mode and a scanning mode; only a plurality of parameters need to be input during operation, so that the experiment process can be simplified, the experiment time is saved, and the method can be used in a ground simulation experiment of SAR system design.
