Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-2, in the embodiment of the utility model, an intelligence digital campus information system, including display terminal and a plurality of portable equipment, display terminal includes controller, display module, power module and wireless receiving module are connected respectively to the controller, display terminal is used for receiving the information that portable equipment sent and shows, the last customized customer end that carries of portable equipment for type information and give display terminal, display terminal just so can come out information display, can be used for announcing score, the three good student's lists etc. of each class, and intelligent speech degree is high, very big reduction the human cost, also provide the basis for paperless official working.

The power supply module comprises a capacitor C1, a resistor R1, a rectifier bridge Q, a relay J and a diode D1, one end of the capacitor C1 is respectively connected with a live wire of 220V alternating current commercial power, a diode D2 and a first input end of the rectifier bridge Q, the other end of the capacitor C1 is respectively connected with an anode of a diode D1 and an anode of a diode D3, a cathode of a diode D1 is respectively connected with a null wire of the 220V alternating current commercial power, a capacitor C2 and a second input end of the rectifier bridge Q, the other end of the capacitor C2 is respectively connected with an anode of a diode D2 and a cathode of a diode D4, an anode of a diode D4 is respectively connected with an anode of a diode D3, an anode of a diode D5 and a resistor R1, a cathode of the diode D5 is connected with a capacitor C3, the other end of the capacitor C3 is respectively connected with an anode of a diode D6, a relay J contact J-1, a base of a triode VT1 and an output end Vo, the other end of the capacitor C4 is connected with the cathode of the diode D6, the collector of the triode VT1 is connected with the other end of the resistor R1, and the other end of the J contact J-1 of the relay is connected with the second output end of the rectifier bridge Q and is grounded. The output end Vo is connected with the controller and supplies power to the controller. The J contact J-1 of the relay is a normally closed contact. The controller adopts a PIC series single chip microcomputer. The portable equipment is a smart phone or a tablet computer.

The half-wave rectification formed by the capacitor C1, the diode D1, the diode D3 and the capacitor C3 has large output current and small ripple because of full-wave rectification, and the full-wave rectification circuit is formed by adding the capacitor C2, the diode D2 and the diode D4 on the basis. Because the diode D5, the capacitor C3 and the output end Vo form a parallel loop, the desired output voltage can be obtained at the output end Vo by setting the values of the voltage stabilizing diodes D5 and D6; the triode VT1, the resistor R1 and the relay J form an overvoltage protection module, when the voltage of the output end Vo exceeds a set value, the triode VT1 is conducted, and the relay J works, so that the normally closed contact J-1 of the relay J is disconnected from the output end Vo, and the protection effect is achieved.
