The invention discloses a software and hardware operation information monitoring method based on a domestic CPU and an operating system environment, including a client and a server connected to each other, setting an agent program on the client to monitor software and hardware operation information data; performing active collection, and the client's The agent program actively collects the software and hardware status information of the security host and sends it to the server; for passive collection, the client agent program passively receives the software and hardware status information key sent by the server, and starts the corresponding acquisition program or The collection script collects the corresponding security host status information, and then sends the collected information to the server. Compared with the existing technology, the software and hardware operation information monitoring method based on domestic CPU and operating system environment can realize the monitoring of software and hardware operation information based on domestic CPU and operating system, and the monitoring method is efficient, concise and has good scalability , you can add new monitoring information items with simple configuration.

The invention discloses a method capable of eliminating signal interference generated by mobile phone signals to radio telescopes. The system defaults to configuring the latitude and longitude of each radio telescope (i=1, 2,...,n); the mobile phone and each radio telescope are to be shut down to specify a silent zone Range and number (usually set to three restricted areas, core area, and quiet area); calculate the user's current latitude and longitude with the latitude and longitude of each radio telescope, and the calculated distance is Distance uti (i=1, 2,..., n); Use the distance algorithm to determine the distance between the user and the nearest radio telescope Distance ut ;Determines whether the user is within the quiet zone range of a radio telescope. The beneficial effect of the invention is that it can reduce the signal interference caused by the mobile device to the radio telescope, so as to obtain more real observation data, thereby providing more reliable data guarantee for the experiment.

The invention relates to a dual loop collecting and tripping interface device. The dual loop collecting and tripping interface device comprises two collecting and tripping circuits arranged redundantly; each collecting and tripping circuit comprises an input module and an interface processing module connected with the input module; the interface processing module is also connected with a processing module and an export module for outputting control signals for splitting and closing the circuit breaker; the dual loop collecting and tripping interface device also comprises a GOOSE input interface module connected with the processing module; each input module comprises a plurality of interface units, and the interface processing module controls the corresponding interface unit; and the dual loop collecting and tripping interface device comprises an optical fiber interface module and a GOOSE output interface module. The dual loop collecting and tripping interface device accesses multiple identical data sources and makes logical discrimination, therefore, the device is upgraded again on the basis of enhanced reliability; the data source and protection tripping of the device are designedinto two loops with independent collecting and independent tripping, therefore, the malfunction of the project can not be caused by the damage of a single device or single loop; the reliability of the system is improved, and the normal operation of the system is ensured.

The invention discloses a Beidou satellite communication technology-based method for intelligently detecting and processing acquired electric energy data. According to the method, the current actual value of the acquired electric energy data of a Beidou satellite is compared with a historical value and an integral electric quantity, and then wrong data caused by the distortion during the transmission process can be automatically identified and processed. If the current actual value is larger than the historical value, the interval time and the difference value between the current actual value and the historical value are further calculated. Meanwhile, the reasonable quantity of generated electric energy within the difference value and the interval time is compared with the integral electric quantity. After that, whether the anomaly of data jump caused by the distortion during the transmission process occurs to the current actual value or not can be judged. According to the technical scheme of the invention, the intelligent detecting and handling problem of abnormal data during the transmission process of the acquired electric energy data of the Beidou satellite to a scheduling main station via a satellite channel can be solved. Meanwhile, the related alarm function for suspicious data is provided at the same time, so that the operation and maintenance personnel can check the data in the timely manner. The operation and maintenance efficiency is improved, while the accuracy and the availability of the acquired data of the Beidou satellite are significantly increased at the same time.

The invention provides a writing track sampling method and device applied to a writing brush. Wherein, the method includes: extracting samples of strokes from calligraphy and painting inscriptions; imitating the writing track of said strokes through a handwriting input device, and reading the writing track data from when the handwriting input device is pressed to write to when it is lifted to stop writing; Wherein, the writing track data includes the coordinates and time of each writing point; the turning point of the writing track data is determined according to the chronological order of each writing point and the coordinates of the writing point; The data is divided into a plurality of stroke segments; the writing track data of the plurality of stroke segments are respectively sampled according to the set sampling method and the samples of the strokes; and the sampling data corresponding to the samples are recorded in the stroke sample database. Through the present invention, the practicability of the stroke sample library is improved.
