Detailed description of the invention
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
One detecting system, be unable to do without sensor, and general sensor generally uses 24V power supply to be powered.If sensor works the most continuously, then most of electricity of electric power system will be used for working sensor；And in reality, sensor gathers a secondary data every a period of time.Solar energy has the advantages such as safe and reliable, noiseless, low stain, but it is more to be affected by weather impact, should not use separately as electric power system.
A kind of solar powered low-power consumption field detection device, as shown in Figure 1, including power module, power conversion module, sensor, microprocessor and wireless module, power module includes solar panel, lithium battery, voltage reduction module and power supply select module, solar panel carries out being energized or pass through voltage reduction module to lithium battery and directly powers, power supply selects module to select lithium battery power supply and solar panel directly to power in good time, the supply voltage of power module is converted into sensor by power conversion module respectively, microprocessor and the running voltage of wireless module, wherein the power-switching circuit of sensor uses band to control the Switching Power Supply conversion chip of end, it is controlled end and is controlled by microprocessor output I/O port, this I/O port output high level of microprocessor, then sensor obtains electric, data are sampled；This I/O port output low level of microprocessor, then sensor must not electricity, in a dormant state, reduce the energy consumption of main power consumption device sensors of field detection device with this.
In the case of sunny, solar panel is directly system power supply, gives lithium cell charging simultaneously；At rainy weather, lithium battery it is system power supply；The selection of power supply mode is arbitrated by power selection circuit.The voltage of solar panel is bigger with the voltage phase difference of lithium battery, it is therefore desirable to first carry out blood pressure lowering process.
The power-switching circuit of sensor uses band to control the Switching Power Supply conversion chip LT3436 of end, and power supply conversion efficiency own is higher, and in the case of dormancy, electric current only has 11 μ A, and its external wiring diagram is as shown in Figure 2.
