Accompanying drawing explanation
Fig. 1 is the block diagram of servocontrol board checking device of the present utility model.
Embodiment
To develop simultaneously embodiment below in conjunction with accompanying drawing, the utility model is described in detail.
Pick-up unit of the present utility model comprises 6 modules altogether:
1, power module: power supplies all in testing process is provided, power supply comprises+27V, ± 15V ,+5V; 220V alternating current is converted to+27V, ± 15V direct supply through AC-DC power module, and+27V direct supply is through DC-DC power module conversion+5V power supply.(AC: exchange, DC: direct current)+27V, ± 15V DC power supply master control board; + 27V DC power supply power board; + 5V DC power supply pot.
2, indicating module: power light, whether powered by power light display power supply normal, the bright explanation of pilot lamp, pilot lamp does not work and illustrates and do not power if powering;
3, link block: each analog channel in the connecting test device of connector one end, other end connecting circuit board, sets up the connection of analog channel and circuit board; The physical connection of pick-up unit and circuit board (master control board, power board) is set up by rectangular electric connector.
4, position module: the output terminal of rotary transformer is by the station acquisition Path Setup physical connection of link block and circuit board, by rotating rotary transformer knob, change rotary transformer output end voltage, the output voltage of rotary transformer changes, and corresponding change also occurs the value of this analog quantity of station acquisition channel acquisition of master control board; Rotating transformer exciting power supply in ± 15V power supply control plate, excitation power supply produces the sine wave of 10kHz, is input in rotary transformer, rotary transformer outgoing position restituted signal S1, S2, S3, S4, in master control board, master control board goes out current location information according to S1 ~ S4 signal receiving.
Acceleration module: adopt pot, by rotating potentiometer knob, change pot output end voltage, with analog rate size, the gyro acquisition channel for master control board gathers.
