The invention relates to a desk cleaning method which is particularly applicable to cleaning of surfaces and bellies of university campus desks and realized through a desk cleaning device. The method aims at campus indoor environments and desk structure characteristics, and fixed-point cleaning is performed on garbage on the surfaces and in the belies of the desks in the form of an inner fixed rail driving cleaning mechanism. The method is high in intelligent degree and capable of positioning the garbage, cleaning the desks and pouring the garbage in a full-automatic manner without manual intervention. The method is particularly suitable for cleaning of the campus desks, and the input and the labor intensity of cleaners are greatly reduced.

The invention discloses a distributed low-cost energy consumption monitoring system for university campuses, which comprises a universal PC (personal computer), a monitoring host, gateways and four types of energy consumption nodes, wherein the universal PC, the monitoring host and a plurality of gateways are connected to a university campus network through an Ethernet, and the plurality of gateways are connected with the plurality of energy consumption nodes through a wireless sensor network. The system disclosed by the invention is low in construction and maintenance costs of a backbone network, convenient and agile; a small core ZigBee module is developed in the system, and embedded into the existing energy consumption detecting instrument, therefore, the energy consumption nodes with a communication networking function are formed, and the existing investment is protected, so that the system is easy to apply and promote; and the gateways of the system are embedded into a Webserver, and release energy consumption data in a webpage form, so that a distributed low-cost energy consumption monitoring system is formed, thereby improving the reliability of the system and facilitating the management and the participation of teachers and students.

A method and associated system for monitoring electrical demand performance in a building, industrial complex or university campus is disclosed. According to a preferred method, historical data is initially complied and statically analyzed to determine demand forecast for a baseline day. Further according to the method, electrical demand is plotted with another indication, more particularly outside air temperature. Additionally the invention provides an electronic alert to building engineers when demand falls outside the expected demand range. Still further a control chart is provided with the expected electrical load range. Outside air temperature is also optionally considered historically and in real time in the method. The invention further contemplates commissioning building engineers to reduce demand when a real time demand is higher than an expected energy demand. A system is also disclosed herein having instrumentation and electronic devices controlled by software and transmitting data.

The invention discloses a bacteriophage for preventing and treating a prawn vibrio parahaemolyticus disease and an expanding culture method thereof. Vibrio parahaemolyticus infected by South American white prawn are used for successfully screening out a strong lytic bacteriophage in seawater, titer of the bacteriophage is up to 1010 to 1012pfu / mL, fermentation period is 8 to 12h, treatment effects are obvious, and the bacteriophage for preventing and treating the prawn vibrio parahaemolyticus disease is of great significance for treatment of diseases causes by the vibrio parahaemolyticus and development of bacteriophage microecological preparations. A storage unit code of the bacteriophage is China Center for Type Culture Collection, address is China Center for Type Culture Collection in Wuhan University Campus, Wuchang Luojia Mountain, Wuhan City, preserved date is December 9, 2016, preservation number is CCTCC NO: M 2016740, a preservation test result is survival, name is vibrio parahaemolyticus bacteriophage VP11, and classification is named as Vibrio parahaemolyticus bacteriophage VP11.

The invention relates to a system for detecting students' late returning and climbing a window into a dormitory of a university campus dormitory building and a detection method thereof. The system comprises a Bluetooth connection end, a student mobile phone end, a teaching staff end, a camera device, a control terminal and a number of persons calculating device. Among them, the teaching staff is located in the duty room of the dormitory building, which is used to record the entrance and exit of students in the teaching building. A Bluetooth connected end is used for connecting that Bluetooth connection to the mobile phone end of students, and a number count device is arranged at the door of each dormitory to record the number of students in each dormitory, and whether the students return late or enter the dormitory by special means is judged by the number of Bluetooth connections and the number of students in the current dormitory building, and the number counting device is sent to theteacher end in time.

The invention discloses a distributed control method for large-scale heating and ventilation air-conditioning systems in university campus buildings. Coordinated operation of the heating and ventilation air-conditioning systems in all regions in a plurality of buildings is achieved by adopting a model predictive control and alternating direction multiplier method, and the sum of the energy cost and the heat energy non-comfort cost is minimized under the constraint that the total input power and the acceptable temperature range of all the regions are not violated. The distributed control methodparticularly comprises the following working procedures that (1) a local controller of the heating and ventilation air-conditioning system in each region is used for predicting the electricity pricein a prediction interval, the external temperature and the user comfort degree preference temperature; (2) optimal input power decisions for a plurality of time slots in the future are given by all the local controllers according to a control algorithm; (3) the input power decision of the first time slot is made to act on actual operation of the heating and ventilation air-conditioning system; and(4) the prediction interval rolls back to one time slot, and the above three steps are repeatedly conducted. The method has the advantages of being high in expandability, high in flexibility, capableof protecting the privacy of a user and the like.
