In traditional fan vibration test macro, be that digital signal is transferred to computer again by the pci data capture card with needing analog signal conversion to be processed in the fan vibration test process, computer is made subsequent treatment to these signals again.But, the pci data capture card of conventional fan vibration test system and special-purpose data line thereof, production cost is all very high; And the pci data capture card can only be installed in the computer with the PCI slot, can't be installed in the portable computer, also must support the use with the data line of special use, and this is portable poor so that whole fan vibration test macro is very heavy.
Summary of the invention
The purpose of this utility model is to overcome shortcoming and defect of the prior art, and a kind of fan vibration test macro based on the Ethernet data acquisition technique is provided.
To achieve these goals, the utility model adopts following technical scheme:
The fan vibration test macro, comprise computer, vibration-testing case and the acceleration transducer that is connected tested fan, acceleration transducer connects the vibration-testing case, the vibration-testing case comprises casing and is located at the interior master control borad of casing, casing is provided with the Ethernet interface that is connected with master control borad, and master control borad connects computer by Ethernet interface.
Wherein, described master control borad is integrated with micro controller unit, ethernet interface circuit, analog to digital conversion circuit and acceleration transducer signals sample circuit.
Wherein, described sensor comprise be located at tested fan rotate the X-axis sensor of radial direction and be located at tested fan rotation axis to the Y-axis sensor.
Wherein, also comprise for the vibration-testing tool of fixing tested fan.
Wherein, also comprise be used to the acceleration transducer signals transmission line that connects described acceleration transducer and described vibration-testing case.
Wherein, described computer also comprises display device.
The beneficial effects of the utility model: acceleration transducer gathers the vibration signal in the fan vibration test process, and is sent to the vibration-testing case, and the vibration-testing case is transferred to computer by Ethernet interface after vibration signal is converted to digital signal.Computer is processed digital signal, and then obtains the supplemental characteristic of every needs.Ethernet technology relies on the many merits such as transmission bandwidth is high, stability is high, long transmission distance, is widely used in the communications industry, thereby makes cost of development and production cost based on the equipment of ethernet technology become quite cheap.The utility model has used the Ethernet data acquisition technique, and cost of development and production cost are lower compared to existing technology; And computer no longer is confined to and need only needs all can be applicable to native system with the computer of Ethernet interface with the computer of PCI slot, comprises the notebook computer of good portability, thereby has greatly improved the portability of whole system.
Description of drawings
Fig. 1 is the functional-block diagram of embodiment.
Fig. 1 comprises following Reference numeral:
Computer-1; Vibration-testing case-2; Acceleration transducer-3.
Embodiment
Referring to Fig. 1, below in conjunction with accompanying drawing the utility model is described in detail.
The fan vibration test macro, comprise computer 1, vibration-testing case 2 and the acceleration transducer 3 that is connected tested fan, acceleration transducer 3 connects vibration-testing case 2, vibration-testing case 2 comprises casing and is located at the interior master control borad of casing, casing is provided with the Ethernet interface that is connected with master control borad, and master control borad connects computer 1 by Ethernet interface.
Ethernet technology relies on the many merits such as transmission bandwidth is high, stability is high, long transmission distance, is widely used in the communications industry, thereby makes cost of development and production cost based on the equipment of ethernet technology become quite cheap.The utility model has used the Ethernet data acquisition technique, and cost of development and production cost are lower compared to existing technology; And computer 1 no longer is confined to and need only needs all can be applicable to native system with the computer of Ethernet interface with the computer of PCI slot, comprises the notebook computer of good portability, thereby has greatly improved the portability of whole system.
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 macro 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.Suppose that vibration-testing case 2 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 1, the bandwidth that need take Ethernet is 4Mbps.And vibration-testing case 2 is supported the Ethernet transfer rate of 100Mbps at least, satisfies the fan vibration test macro fully to the data transmission bandwidth requirement, and also has significantly room for promotion than traditional scheme on the performance.
The master control borad of vibration-testing case 2 is integrated with micro controller unit, ethernet interface circuit, analog to digital conversion circuit and acceleration transducer signals sample circuit.The acceleration transducer signals sample circuit is used for gathering the output signal of fan vibration test process acceleration transducer 3, and is sent to analog to digital conversion circuit.Analog to digital conversion circuit is digital signal with the analog signal conversion that collects.Micro controller unit can Real-time Obtaining after the analog to digital conversion circuit conversion digital signal and be transferred to computer 1 by Ethernet.Acceleration transducer 3 output signals that computer 1 can collect by the vibration-testing case by the Ethernet Real-time Obtaining, and this signal processed, and then obtain the supplemental characteristic of every needs.
Because being vibrated to the skew that I haven't seen you for ages produces both direction, so sensor comprises that being located at tested fan rotates X-axis sensor radially and be located at the axial Y-axis sensor of tested fan running, can accurately collect vibration signal.Also comprise for acceleration transducer 3 signal transmssion lines that connect acceleration transducer 3 and vibration-testing case 2.
Consider the convenience of vibration signals collecting, also comprise the vibration-testing tool for fixing tested fan.
