Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Embodiment
A kind of wireless remote camera shooting meter system terminal as shown in Figure 1, it is made up of electric battery, power module, flashlamp, OV7725 camera module, XC6221A332MR 3.3V LDO, SI4463 wireless module, C8051F920 main control module, DSP control module, and its course of work is as follows:
System is sent and Received signal strength by SI4463 wireless module, and electric battery is made up of the dry cell of 3 joint 1.5v, through XC6221A332MR 3.3V LDO from electric battery power taking, converts out 3.3V voltage for SI4463 wireless module and C8051F920 main control module.
C8051F920 main control module and SI4463 wireless module are connected by SPI interface (Serial Peripheral Interface), when SI4463 wireless module receive check meter order time, C8051F920 main control module reads data, confirms that the machine is the need of collection water meter information.
If confirm that needs gather, by the enable control pin of C8051F920 main control module opening power module, XC6221A332MR, XC6221B18AMR and XC6221B132MR tri-submodules start from electric battery power taking, convert out 3.3V, 1.8V and 1.3V voltage, be combined into two groups of power supplys and supply camera module and DSP control module use respectively.
DSP control module is started working by reset, obtains operational order by serial ports from C8051F920, lights LED flashlamp, passes through I
2c bus sends shooting order to OV7725 camera module, and the view data passed back via parallel port reception camera module, data receiver is complete closes LED flashlamp again.
Data are for data processing by DSP control module after arriving, then pass C8051F920 main control module back by serial ports.C8051F920 receive after data through by serial ports by SI4463 wireless module by data upload, data transmission terminates rear C8051F920 powered-down module with system under reducing holding state to the energy ezpenditure of electric battery, prolongation service time of battery.
Due to the picture comparatively large (the gray scale picture of 320*240 pixel) taken based on OV7725 camera, if so large picture is directly uploaded through wireless, the time of needs is longer, to being kind of a challenge serviceable life of battery.Here adopt, through DSP control module, compression cutting and binary conversion treatment are carried out to picture, greatly reduce the quantity of information of picture.
