Description
Technical field
The present invention relates to a kind of smart classroom Energy Saving Control and status inquiry system, belong to school's auxiliary equipment and automation field.
Background technology
The classroom of current school scarcely has function and the equipment of Energy Saving Control and inquiry, thus cause waste and the inconvenience of energy: 1, classroom state is failed to understand, search inconvenience: find self-study classroom, particularly in the stage of preparing for the examination, a lot of classmate's association spends long time to solve searching self-study classroom, or wasting a lot of time also can not find available classroom, because some classrooms are less than open, in open classroom, also there is full situation; 2, waste of energy is serious: classroom without thin and weak man's but light yellow, or in the daytime that light is enough strong the lamp also light yellow in classroom, then or classroom in review one's lessons but full light yellow of lamp etc. in classroom several individual with regard to certain region memory.Also have in recent years and can carry out the simple equipment controlled to classroom, as application number be 201210293214.3 and application number be the patent of 201420076465.0, the former passes through the lamp dimmer in classroom and the wireless connections of ipc monitor device, thus controls the switch of religion indoor lamp; By master controller, the latter judges that switch lamp is carried out as idle or room for individual study in classroom; Information issued is carried out by information delivery apparatus.These two kinds of technical schemes are all unify to control to the lamp in whole classroom, can not need to carry out switch lamp for the light personnel of zones of different in classroom, cause the waste of electric energy; And all can not effective strength in real-time statistics classroom, reliable tutorial message cannot be provided for the classmate finding classroom.
In order to solve the problem, allow classmates save time, simultaneously economize energy, needing one badly can real-time query classroom state, and can control religion indoor power supply, the system of economize energy.
Summary of the invention
The object of this invention is to provide a kind of smart classroom Energy Saving Control and status inquiry system, this system can according to the switch of the distribution of people in classroom and bright strength control lamp, and statistics religion occupancy and light opening and closing situation, saved the energy; This system can realize, by mobile phone or the PC terminal real-time query to religion occupancy, having saved student's time, having improve the utilization factor in classroom; And this system cost is low, low in energy consumption, reliable.
The present invention realizes the technological means that its goal of the invention takes: a kind of smart classroom Energy Saving Control and status inquiry system, comprising:
Be arranged on the infrared two-way emission type sensor of the inside and outside both sides in each, classroom respectively, the output pin of infrared two-way emission type sensor is connected with the input pin of Zigbee main control chip one, forms classroom number monitoring means;
Pyroelectric infrared sensor is distributed in the relay place of classroom lighting, the output pin of infrared thermal releasing sensor is connected with the input pin of Zigbee main control chip two, the output pin of Zigbee main control chip two is connected with the control signal input pin of relay, forms local, classroom light control unit;
Light sensor is arranged in classroom, and the output pin of light sensor is connected with the input pin of Zigbee main control chip three, forms classroom brightness monitoring unit; Described Zigbee main control chip three carries out Wireless Data Transmission by Zigbee protocol and Zigbee main control chip two;
Zigbee main control chip four is connected with ARM microprocessor, and ARM microprocessor is connected with wireless network card simultaneously, configuration information state transmitter unit; Described Zigbee main control chip four carries out Wireless Data Transmission with Zigbee main control chip one and Zigbee main control chip two by Zigbee protocol simultaneously;
The wireless data information that wireless network card transmission in the wireless network card reception information state transmitter unit of director server comes, sets up also more new database, for mobile phone or PC terminal inquiry.Also can apply for system development mobile phone, realize user and log in, after being connected with director server, classroom number information can be inquired about.
Zigbee main control chip used in the present invention combines Zigbee protocol stack, can carry out ZigBee wireless telecommunications, and a kind of chip that can store data, process, transmit simultaneously, as the cc2530 chip of IT company.Zigbee protocol is a kind of low-power consumption territory fidonetFido, and the technology specified according to this agreement is the wireless communication technology of a kind of short distance, low-power consumption.
Principle of work of the present invention is:
By judging the induction order being arranged on the infrared two-way emission type sensor of the inside and outside both sides in each, classroom, judge that people enters classroom or leaves classroom, thus the counting realized religion occupancy and monitoring, and by Zigbee main control chip one, number information in classroom is radioed to Zigbee main control chip four by Zigbee protocol, and and then be transferred to director server for inquiry.
The brightness in light sensor monitoring classroom, and by Zigbee main control chip three, monochrome information in classroom is radioed to Zigbee main control chip two by Zigbee protocol; When classroom monochrome information is greater than setting threshold value (namely bright daytime), the relay that main control chip two controls local, classroom light control unit is in off-state all the time.Corresponding pyroelectric infrared sensor is distributed in each relay place of classroom lighting, and (relay is on average scattered in the regional of classroom, the switch of the light of each Control region), the religion room brilliancy come when transmission is less than setting threshold value (namely when night and dark weather), and pyroelectric infrared sensor detects in region when having people, then Zigbee main control chip two-way is crossed relay and is turned on lamp in this region, otherwise by the lamp in this region of cut-off; The opening and closing situation of the lamp of region is radioed to Zigbee main control chip four by Zigbee protocol by Zigbee main control chip two simultaneously.
Zigbee main control chip four by the data information transfer after collecting to ARM microprocessor, and further by wireless network card wireless transmit to director server; The wireless network card of director server receives the transmission of information state transmitter unit and carrys out wireless data information, sets up also more new database, for mobile phone or PC terminal inquiry; Staff is by classroom personnel distribution and light opening and closing situation in mobile phone or the whole teaching building of PC terminal inquiry, and student by mobile phone or PC terminal inquiry religion indoor occupant distribution situation, thus determines to review one's lessons place.
Compared with prior art, the invention has the beneficial effects as follows:
One, by classroom brightness monitoring unit and local, classroom light control unit, control the opening and closing of local light in classroom, when available light is enough, do not turn on light; And when available light is inadequate, and when having the regional area of people near lamp, just turn on the lamp in this region; Thus both met the lighting requirement of Students ' Learning, avoid again the waste of the energy to greatest extent, good energy-conserving effect.
Two, number monitoring means in classroom is by the correlation infrared sensor service condition in each classroom in real-time statistics teaching building or even in school simply and easily, is convenient to student and selects room for individual study more quickly, saved student's time, improve the utilization factor in classroom.
Three, adopt the wireless connections that the Zigbee wireless network based on Zigbee protocol realizes in classroom between each unit, install and use cost low, power consumption is few, and reliable.
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
