The invention discloses a video data processing method and a video data processing device. The video data processing method includes: converting one or more channels of original video data acquired currently into video data in a preset format by means of image signal processing; according to channel number of a to-be-outputted video bitstream, adopting a Resize module in an OMAP (open multimedia application platform) processor to subject each branch of video data in the preset format to scaling for one or more times; coding and packaging the scaled video data to output a multi-channel video bitstream. According to the technical scheme, bitstream data in different demands can be generated, and low-resolution real-time video previewing on a remote network platform and local high-resolution videorecording of the same channel of data can be realized efficiently and simultaneously.

The invention discloses a gas outburst sensor based on a sound wave principle and belongs to a gas sensor. The gas outburst sensor comprises a casing, a frontal sound cavity, an ultrasound piezoelectric film, lateral sound cavities, metal films, fixing electrode plates and a lead, wherein the frontal sound cavity is arranged in front of the casing, the lateral sound cavities are arranged on the side of the casing, the ultrasound piezoelectric film is connected in the frontal sound cavity, the metal films and the fixing electrode plates are sequentially connected in the lateral sound cavities, the lead and the ultrasound piezoelectric film are connected at the back of the casing, at the same time, the lead, the metal films and the fixing electrode plates are arranged, the frontal sound cavity and the ultrasound piezoelectric film form an ultrasonic detector, the number of the lateral sound cavities, the metal films and the fixing electrode plates is respectively two, the lateral sound cavities, the metal films and the fixing electrode plates form two low-frequency acoustic detectors, and by the aid of detection of high-frequency sound waves and low-frequency sound waves, sound waves produced by gas jet which is ejected out of seams of coal layers can be analyzed. The gas outburst sensor has the advantages that high-frequency sound wave signals and low-frequency sound wave signals which are ejected out by the high-pressure gas in the coal layers through seams of the coal layers can be detected, and real-time monitoring for mine gas outburst is achieved.

The invention discloses a non-contact real-time monitoring system and method for surrounding rock and face deformation in model tests, comprising: a laser emitting device is fixed on a balance support through a support, and the laser emitting device and a data transmission module are respectively connected to a power supply module The laser emitting device includes a laser emitting device body and an internal data acquisition module, a front laser cannon and a rear laser cannon are respectively arranged on the front and rear two end faces of the laser emitting device body, and several Circumferential laser cannon. Beneficial effects of the present invention: through the angle-adjustable laser emitting device and the circular laser cannon, the problem of simply using multiple monitoring elements embedded in the model and the survival rate of the elements cannot be guaranteed is overcome, and the simulation effect of a large number of embedded monitoring elements is also reduced It also solves the problem of real-time monitoring of multiple cross-sections at all angles.

The invention discloses a 10kV wireless communication distribution network microcomputer protection device, including: distribution network terminal equipment, a distribution network communication device connected to the distribution network terminal equipment through RS485, and a client, the client includes a distribution network communication device information receiving center and customers Terminal mobile phones, among which, the distribution network communication device adopts a circular question-and-answer method for remote monitoring, and obtains the remote signal volume and telemetry of at least 5 sets of distribution network terminal equipment in the switching station; the distribution network communication device uses GPRS wireless network, 230MHz VHF The radio station and short message upload the remote signaling amount and remote measurement of the distribution network terminal equipment in the 10kV switching station to the client; the distribution network terminal equipment uses the radio station as a backup communication channel, and the communication system adopts a hot backup dual channel. This solution can solve the problem of real-time monitoring of battery capacity because the remote terminal in the existing distribution automation system is equipped with a battery that is DC and has not been maintained in deep discharge for a long time, and its performance will decline rapidly over time.

The invention discloses a remote access method for displaying multi-source data in the same picture, comprising the following steps: 1) the graphic browser of the main access system parses the graphic file, and obtains keyword information of the system equipment to be accessed; 2) data refresh The client will classify the same graphic file according to the keyword information to be accessed by different system devices; 3) The data refresh server will establish a data cache; Send a data request, the system graphics gateway machine gets the request, and sends the data to the data refresh server; 5) The data refresh server of the main access system detects that the cached data has changed, and returns the changed data to the data refresh client; 6) The graphical browser of the main access system refreshes the corresponding equipment data information, shortens the time for dispatchers to find problems, improves the security of the power grid, and has a good application prospect.
