The range finding director circuit diagram that Fig. 1 provides for the utility model;
Embodiment
Power module input 9～24V DC voltage, output 5V and 3.3V each one the tunnel, 5V voltage is supplied with bus interface RS485,3.3V provides working power for single-chip microprocessor MCU, RS232, laser ranging module and laser tube module; The RS485 Bus Interface Chip is transmitted data between bus and single-chip microprocessor MCU; RS232 receives the data that the laser ranging module transmits under the level control of control line PWR and CTR; Driving circuit provides working power for the laser tube module under the control of single-chip microprocessor MCU; Single-chip microprocessor MCU is responsible for parsing, the processing of bus data as the main intelligent chip of control module, with the state of control laser tube module.
The state of range tube instrument is described below.
1, holding state
After powering on, single-chip microprocessor MCU provides power supply by driving circuit for the laser tube module, and the laser tube module is sent a branch of visual red laser; The RD that is connected with single-chip microprocessor MCU is that low level, PWR and CTR are high level.
2, duty
Self querying command of receiving by RO that monitoring host computer transmits when single-chip microprocessor MCU, CTR becomes high level again by the time that high level becomes low level continuous Query order request, the laser ranging module spreads out of measurement data (if MCU does not receive the data that the laser ranging mould transmits, the low pulse of PWR output, open the laser ranging module, repeat the front and receive querying command step afterwards), RD becomes high level, by RX connecting line MCU the data that receive are repacked, again data are passed to RS485 by the DI connecting line, RS485 issues monitoring host computer by bus, and the RD value is in accepting state for low level.
Those skilled in the art can also carry out various modifications to above content under the condition that does not break away from the definite spirit and scope of the present utility model of claims.Therefore scope of the present utility model is not limited in above explanation, but determine by the scope of claims.
