The invention discloses a fully-mechanized coal mining face equipment cooperative automatic control system and method. A coal mining machine-mounted module, a scraper conveyor-mounted module and a crusher-mounted module are connected with one another through electric signals of wireless receiving and transmitting modules so as to acquire real-time parameters of each set of equipment and transfer the parameters to one another, and the controllers of the equipment circularly and automatically adjust the parameters of the equipment, and therefore, the automatic control system can achieve an optimal operation state; and when the coal carrying capacity of a scraper conveyor is too high or too low, the automatic control system of the invention can automatically adjust the parameters of a coal mining machine, the scraper conveyor and a crusher so as to prevent the blockage of a fully-mechanized coal mining face and improve the coal mining efficiency of the fully-mechanized coal mining face. With the system and method of the invention adopted, on the one hand, the physical labor of workers can be reduced, the personal safety of the workers can be ensured, humanized and unmanned mechanized mining requirements can be satisfied, and on the other hand, delay and misjudgment can be eliminated, the device will not always be in a maximum power output state; and therefore, high yield, high efficiency and low energy consumption can be achieved.

The invention discloses an idle speed monitoring method based on data of the internet of vehicles. The idle speed monitoring method comprises the following steps of (1) collecting driving data of a vehicle from the beginning of the new vehicle to the preset driving mileage from the internet of vehicles, and obtaining a normal range of the idle speed of the vehicle according to the driving data; (2) collecting driving data of the vehicle after the preset driving mileage from the internet of vehicles, and judging whether the idle speed of the vehicle is within the normal range according to the following driving data; and (3) detecting whether relevant parameters of the idle speed of the vehicle are normal in sequence if the idle speed of the vehicle is not within the normal range, and finding faulty parts of the vehicle according to detection results. According to the idle speed monitoring method, whether the idle speed of the vehicle is normal can be monitored in real time, and the failure of the idle speed of the vehicle can be identified and diagnosed.

A human-machine interaction method based on visual stimulations. The method can be applied to multiple new technical fields of display, which comprise but are not limited to the fields of virtual reality (VR), augmented reality (AR), mixed reality (MR), holographic projection and glasses-free 3D. The system consists of three parts: a human body biological collection apparatus, a software client for human-machine interaction and a display terminal. Input ports of the software client are connected to a human body physiological signal collection device (in a wired or wireless manner); a user wears the collection device, and communication ports of the client are respectively connected to communication ports of a display module by means of a multichannel communication module. Firstly, the system is initialized, and then starts to run based on a control method of visual stimulations (an object flicker or distortion). If a target is a text input target, an interface is switched to a text input interface, and texts are inputted by using a physiological signal detection algorithm for a human body. If the target is not a text input target, the type of information is determined by using a detection algorithm of a specific physiological signal and visual stimulation feedback information, so as to complete the interaction. Search and switching can be performed among text input boxes, selection options and multiple directories, and a bottom layer of the directories can be reached, so as to select a target.

The invention relates to a wearable device and a method for performing a registration procedure therein. The wearable device comprises a light source, a light sensor and a microcontroller for performing the method. In the method, the light source is started to emit detection light, and then the light sensor senses reflected light. The light intensity of the reflected light is then calculated. At this time, a registration value is generated according to the light intensity, and particularly, detection light of a frequency is registered as the registration value as a basis for determining whether the wearable device is properly worn on the human body. For example, when a wearable device may be worn on a person's wrist, the registration value is used to detect whether the wearable device has been distanced from the person's wrist.

A sterility test method includes: selecting strain and culture medium, preparing bacterial cultures, transcribing fingerprint characteristics in thermograms as indices to verify the characteristics, drawing the thermodynamic parameters of the thermogram, determining the positive judgment index and performing sterility test for the samples. A fully-enclosed bacteria collecting ampoule incubator includes bacteria collecting ampoule system, sample and liquid feeding system and peristalsis liquid discharge system. The sample and liquid feeding system is connected with the bacteria collecting ampoule system by the liquid intake tube; and the bacteria collecting ampoule system is connected with the peristalsis liquid discharge system by the liquid drainage tube. The invention is characterized by short inspection time, high sensitivity, high automation and accurate test results on microbial contamination. It can also provide the overall process curve on the growth conditions. Such curve is provided with relatively favorable fingerprint, which enables qualitative analysis on the microbial contamination conditions.
