Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in Figure 1, full-automatic power supply comprehensive detector, comprises three-phase four-wire system power supply, U2 elementary sources, load, relay K, MCU processor, power module, oscillograph, hummer BZ, computing machine.The input end of described U2 elementary sources, load, MCU processor and power module is all connected with three-phase four-wire system power supply, oscillograph and load outputs are all connected with power supply to be measured, the positive pole of U2 elementary sources output terminal is connected with relay input end, negative pole is connected with power supply to be measured, relay K output terminal is connected with power supply to be measured, output loop is connected with MCU processor, MCU processor output terminal is connected with hummer BZ, and MCU processor turns 485 communication modules by a RS-232 and is connected with load.
Computing machine turns 485 communication modules by the 2nd RS-232 and is connected with MCU processor.Oscillograph output terminal is connected with computing machine by USB line.The negative pole of U2 elementary sources and load outputs is connected to the first shunt and the second shunt, and described first shunt and the second shunt output terminal turn 485 communication modules with the 2nd RS-232 respectively and MCU processor is connected.
Detector also includes input current table, output current table, input voltage table, and the RS485 bus that described input current table, output current table, input voltage table all turn 485 communication modules by the 2nd RS-232 is connected with MCU processor with the first shunt.
Detector comprises the fan control circuitry containing temperature sensor.
During concrete enforcement: respectively get out of phase AC220V in three-phase four-wire system power supply respectively to U2 elementary sources, MCU processor, power module and load supplying, U2 elementary sources, power module provide direct supply respectively to power supply to be measured, oscillograph, and load simultaneously can consume the electric current of power supply to be measured.
Computing machine turns 485 communication modules by a RS-232, the 2nd RS-232 turns 485 communication modules and MCU processor establishes a communications link, and send the duty of the equipment such as instruction pilot relay, U2 elementary sources, load and power supply to be measured, input current table, output current table, input voltage table, the each detection data of in good time collection as exported overshoot, no-load power consumption, output voltage, output voltage precision etc., and are uploaded to computing machine.Computing machine controls oscillograph by usb bus and collects figure.The sound that qualified situation in power supply test process is sent by hummer BZ shows.The I/O port of the MCU processor of hummer BZ use is here PC13, use GPIO_SetBits (GPIOC, GPIO_Pin_13) instruction makes hummer BZ sounding, uses GPIO_ResetBits (GPIOC, GPIO_Pin_13) instruction to make hummer BZ stop sounding.If in test process wherein one be judged to be abnormal, the short sound of hummer BZ tri-sound; If tested power supply feature all by time, hummer BZ short sound one sound; When wherein having any one and more than one abnormal, hummer BZ two sound is long to be rung.
Detector has fan control circuitry in addition, user in use, temperature sensor detection system interior environment temperature, and temperature information is transferred to the single-chip microcomputer on fan control circuitry plate, if when temperature is higher than setting value, single-chip microcomputer sends instruction and allows relay adhesive, makes blower fan work (AC220V powers), each circuit devcie can be prevented to damage because of temperature overheating, ensure that full-automatic power supply comprehensive detector reliably works.
