A system equipment management-based negative pressure wound therapy system comprising a system equipment management device (9) for use in detecting working parameters of equipment in the system, in processing and storing a processing result, and in judging whether an aging or abnormality alarm command has been issued, a display device (10) for use in displaying the processing result stored by the system equipment management device, and an alarm device (11) for use in issuing alarm on the basis of the alarm command. The wound therapy system is capable of detecting the working parameters of the equipment, such as the usability, temperature, humidity, voltage, airway, and other system status, and capable of processing and recording the data. When the corresponding working parameter is judged to be abnormal or have aged, the alarm command is issued and the processing result is displayed. The user is provided with a real-time and comprehensive knowledge of the equipment operation status to handle equipment aging and irregularity, thus improving system stability and safety.

The present invention relates to temperature measurement systems. The metal wall temperature measurement system of the rotary air preheater is composed of an online continuous temperature measurement device and a receiver. The online continuous temperature measurement device is installed at the lower part of the metal heat storage body of the rotary air preheater and rotates with the metal heat storage body. The online continuous temperature measurement device is composed of a temperature measuring probe, a compensation wire, a wireless temperature sensor and an incubator. The patch thermocouple is connected to the wireless temperature sensor through the compensation wire. The wireless temperature sensor is placed in the incubator to keep the wireless temperature sensor within the operating temperature range. Inside, the wireless temperature sensor is connected to the receiver through a wireless signal, and the receiver is installed within the transmission distance of the wireless temperature sensor. The use of this device will enable power plant operators to keep track of the operating status of the air preheater, avoid low-temperature acid corrosion, ash blocking, secondary combustion, etc., and ensure safe operation. At the same time, it can also control the operating parameters of the air heater and the exhaust gas temperature according to the measurement data, so as to realize economical operation.

A video anomaly detection method based on machine learning, comprising the following steps: 1) video file reading: read the video file as bmp image data frame by frame; 2) video anomaly detection: detect the decomposed image , the process is as follows: a) the picture is too bright, the picture is too dark; b) the gain is disordered; c) blurred and blocked; d) striped interference and scrolling; e) snowflake interference; f) jitter; g) color cast; h ) freeze; i) blue, black screen; 3) machine learning: compare the similarity of the video judged as abnormal with the same type of misjudged video in the database according to the abnormal code, and judge whether the current video is misjudged. The invention has comprehensive detection, self-learning and improving ability, and high accuracy.

The invention relates to a divisional application of an invention with the application number being 202010752659.8. The invention discloses an online monitoring method for key process parameters of a drying cylinder of a paper machine, which comprises the steps of establishing a quaternary partial differential equation set process model which takes the temperature (Tp) and the humidity (u) of paper at a monitoring part of a drying part and the temperature (Ta) and the humidity (AHa) of air in a bag area at the monitoring part as unknown quantities through conservation of materials and energy in the drying process, then taking process data which is easily acquired in real time in the actual papermaking drying production process as a known quantity, an initial value and a boundary condition, and solving the quaternary partial differential equation set process model established in the invention to obtain real-time data of key process parameters of a papermaking drying part, thereby achieving online monitoring of the paper drying process, avoiding black box operation, being capable of accurately mastering the operation condition of the drying part of the paper machine, and providing possibility for evaluation of the drying capacity and the energy efficiency level of the drying part of the paper machine.

The invention relates to a comprehensive loss-reducing and energy-saving distribution network big data system. The check range extend to electricity user terminals, which is different from the existing power system which stipulates that the check range only extends to 10kV high-voltage distribution rooms and 0.4kV low-voltage distribution rooms. Data collectors are arranged at user terminals to collect a variety of electricity data, including dynamic data and static data, of the user terminals, the collected data is managed hierarchically, data gatherers gather the data of the user terminals, the data of the gathers is gathered to sub-stations arranged in region (area) management centers, and the data of the regional (area) management centers is gathered to master stations arranged in branch management centers. The comprehensive loss-reducing and energy-saving distribution network big data system employing the structure has the advantage that the system can provide accurate and detailed data for distribution network planning and designing, improve the level of distribution network management, and improve the reliability and safety of power supply and the timeliness of accident handling.

The present invention provides a data processing method and system, the method is: acquiring the switch information of the access switch connected to the core switch of the data center, and acquiring the server information of the server connected to the access switch; using the specified monitoring system, Acquiring the first flow transmission information between the access switch and the core switch, and obtaining the second flow transmission information between the server and the access switch; responding to the user's operation instruction, displaying the corresponding information of the access switch on the front-end display interface The switch information and the first traffic transmission information, and the server information and the second traffic transmission information corresponding to the presentation server. According to the information displayed on the front-end display interface, network engineers can fully grasp the operation status of the data center, and do not need to set up network traffic collection adapters, reducing the maintenance cost of the data center.

A provided distribution line tour-inspection system based on GIS and GPS consists of a tour-inspection terminal and a background server, data is transmitted between the tour-inspection terminal and the background server through a front-end processor; the background server is provided with an tour-inspection task management module, a tour-inspection task query statistics module, an identification management module and a database module; and the tour-inspection terminal is provided with a GIS module, a GPS module, a tour-inspection image management module, a tour-inspection task operation module, a tour-inspection equipment query module, a defect information module and a scanning synchronization module. After a line patrol person arrives at a demanded inspection tour point, the tour-inspection terminal automatically records the geographical position information of the person and the current time. The line patrol person also can fill in inspection tour information on the tour-inspection terminal. Therefore, the working efficiency is improved while the cost is effectively reduced.
