Casing-1; Ethernet interface-2; Data acquisition control case-3; Fan power supply-4; External computer-5; Fan power supply connection interface-6; Fan detects interface-7; Ethernet-8.
Embodiment
Referring to Fig. 1 and Fig. 2, below in conjunction with accompanying drawing the utility model is described in detail.
Referring to Fig. 1, the data acquisition control case 3 of the present embodiment comprises casing 1 and the master control borad of being located in the casing 1, and casing 1 is provided with the Ethernet interface 2 that is connected with master control borad, and master control borad carries out data communication by Ethernet interface 2 and external computer 5.
Wherein, master control borad is integrated with micro controller unit, ethernet interface circuit, high-speed A/D conversion circuit, fan electrical current signal sample circuit, rotation speed of the fan feedback signal sample circuit, fan control signal output circuit and fan power supply switch.Fan electrical current signal sample circuit, rotation speed of the fan feedback signal sample circuit and high-speed A/D conversion circuit are converted to digital signal with the current signal in the fan test process and speed feedback signal, the microcontroller device unit of master control borad can obtain these digital signals in real time, and these digital signals are transferred to external computer 5 by Ethernet.Master control borad can receive the instruction that external computer 5 sends by Ethernet, and by fan control signal output circuit output pulse signal fan is controlled and according to command content the fan power supply switch is switched according to command content.
Ethernet chip in the ethernet interface circuit of the present embodiment is supported 100Mbps and 10Mbps Ethernet data transfer rate at least, and transmission speed is fast.NI PCI-6220 data collecting card commonly used in traditional electric property of fan test system is as example, and the ADC chip resolution of data collecting card is 16 to the maximum, and its sampling rate is 250Kps to the maximum.Tentation data gathers control box 3 and comes image data with the ADC of 16 bit resolutions and the standard of 250Kps sampling rate equally, and these data transmission are arrived computer, and the bandwidth that need take Ethernet is 4Mbps.And data acquisition control case 3 is supported the Ethernet transfer rate of 100Mbps at least, satisfies the conventional fan electrical performance test system fully to the data transmission bandwidth requirement, and also has significantly room for promotion than traditional scheme on the performance.
Referring to Fig. 2, the electric property of fan test system of the present embodiment, not only comprise data acquisition control case 3, also comprise fan power supply 4, external computer 5, the Ethernet interface 2 of data acquisition control case 3 connects external computer 5 by Ethernet, external computer 5 connects fan power supply 4, and fan power supply 4 connection data gather control box 3.Particularly, external computer 5 connects fan power supply 4 by Serial Port Line.Tested fan can be not limited to one.
The electric property of fan test system performing step of the present embodiment is as follows:
Particularly, data acquisition control case 3 is provided with fan power supply connection interface 6 and fan detects interface 7, fan power supply 4 gathers control box 3 by fan power supply connection interface 6 connection data, and fan detects interface 7 connection data by fan and gathers control box 3.Fan power supply 4 connects fan power supply connection interface 6 by wire, and fan detects interface 7 and connects fan by wire.In the accompanying drawing 1, these two interfaces all are located at the front of casing 1.But be easy-to-connect, avoid wiring chaotic, fan power supply connection interface 6 can be located at the back of casing 1.
Factor data gathers control box 3 inside and does not contain fan power supply 4, must rely on outside fan power supply 4 and could give tested fan power supply.Therefore the power supply mode of tested fan is: external computer 5 sends the Voltage-output instruction to fan power supply 4 by Serial Port Line, and fan power supply 4 arrives data acquisition control case 3 according to command content output specific voltage; External computer 5 then sends instructions to data acquisition control case 3 by Ethernet, data acquisition control case 3 switches the fan power supply switch according to command content, the voltage that obtains from fan power supply 4 just can output to fan detection interface 7 by data acquisition control case 3 internal circuits, and the voltage that fan detects interface 7 acquisitions arrives tested fan by wire transmission.
