Many details are stated.It may be evident, however, that these embodiments can also be realized in the case of these no details.
In other examples, for the ease of describing one or more embodiments, known structure and equipment are shown in block form an.
Fig. 1 shows the principle of the control system of the deck test device of the embodiment of the present invention.
As shown in figure 1, the control system of deck test device provided in an embodiment of the present invention includes six major parts, point
Wei not power initiation part, the collection amplifier section of pull pressure sensor analog signal, stay-supported displacement encoder and grating scale
Orthogonal signalling collecting part, motion control portion, power drive portion and the industrial computer part of displacement transducer, it is right separately below
This five part is described in detail.
First, industrial computer part
Industrial computer installs XP or WIN7 operating systems, and the basic demand of industrial computer is：It is more than double-core, 2G internal memories, with extremely
Few 3 PCI slots.PCI slot inserts AD analog data acquisitions card, encoder data capture card and motion control card respectively, this
Specifically using PCI8018 models as AD analog data acquisition cards in invention, adopted using PCI2394 models as encoder data
Truck, using PCI1010 models as motion control card.

Connecting to neutral line.QF1 is power switch, is spaced apart for 16A.When pressing SB2 buttons, KM1 adhesives, KM1 auxiliary contact are short by SB2 both ends
Road, form self-insurance.KM1 main contacts adhesives, whole control system are powered.When pressing SB1 buttons, KM1 coil blackouts, KM1 is auxiliary
Help and disconnected with main contacts, whole control system power-off.The advantages of this Power Management Design, is：Under power-off condition, control system is not
Can be auto-power on.Ensure electricity safety thereon.
3rd, pull pressure sensor analog signal amplifier part
It is respectively 100N, 500N, 1000N, 3000N, 10000N that the present invention is configured with five pull pressure sensor altogether, according to
Corresponding pull pressure sensor is installed in the requirement of measurement range.
Pull pressure sensor mounting means is：One end is connected to the output end of electric cylinder, and the other end is connected to tested part
On.The excitation power supply of pull pressure sensor is direct current ± 5V, is converted to force value after pull pressure sensor stress corresponding
Voltage signal exports.This voltage signal and force value linear change.Because this signal is very faint (mv magnitudes).And industrial computer PCI numbers
It is ± 5V data inputs according to capture card.Therefore before industrial computer is sent into, it is necessary to perform Linear Amplifer to signal.Pull pressure sensor
The signal of collection is acquired by the PCI8018 capture cards being inserted in industrial computer.

The gain design of the differential amplifier of the second level is 1 by the present invention, that is, only does the additive operation of two voltage.And instrument is put
The gain of big device is by resistance RgainTo determine.
The gain of circuit is：
The amplifier of rightmost, resistance mark R2And R3It is the differential amplifier-chain of standard, Rgain=R3/R2, and it is differential defeated
Enter resistance=2*R2；Two, left side amplifier is then the buffering of input；Work as RgainWhen being removed (opening loop), two buffer stages are only
It is unity gain buffer；Under this state, gain is equal to R3/R2, and buffer stage provides high input impedance.Buffer
Gain can increase because the negative-feedback of shunting caused by the electric current being placed between negative input and ground connection.It is and reversely defeated at two
Enter to be put into a resistance RgainThe advantages of be：Increase the difference mode gain of buffer stage, and common-mode gain is equal to 1.
If have same gain during individualism, it will increase the common mode mutual exclusion ratio (CMRR) of circuit, can to delay
Bigger common-mode signal can be handled by rushing device.RgainAnother advantage be only with a resistance to carry more gain, rather than one
Right, the problem of can avoiding resistors match, is (although two R1Need the gain matched), gain, which can pass through, only changes Rgain's
Value, and the gain for changing amplifier need not change other resistors match.
