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.
A kind of field detection device of low-power consumption, as shown in Figure 1, including power module, power conversion module, sensor, microprocessor and wireless module, the supply voltage of power module is converted into the running voltage of sensor, microprocessor and wireless module by power conversion module respectively, 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, samples data；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.
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.
According to the design principle of low-power consumption, described microprocessor uses 16 single-chip microcomputer MSP430F247 of super low-power consumption equally, and its dominant frequency is when 1MHz/2.2V, and running voltage only has 270 μ A；Under standby mode, current drain is only 0.8 μ A.
Further, described wireless module uses remote wireless transmission module KYL-320L of band park mode, the dormancy pin of wireless module is controlled by another output I/O port of microprocessor, wireless module will be when receiving terminal sends data, after the dormancy pin of wireless module is set high 150ms by microprocessor, wireless module enters duty；After data are sent completely, the dormancy pin of wireless module is dragged down by microprocessor, and wireless module enters park mode.
When the low power operation flow chart of system is not as it is shown on figure 3, system works, single-chip microcomputer to be made is operated in bursty state, and the most of the time is under low-power consumption mode；System electrification, after single-chip microcomputer completes to initialize, enter low-power consumption mode, third before, the power supply of sensor is disconnected, wireless module is in a dormant state, after only timer interruption wakes up MSP430F247 up, just triggering CPU and run, probe power is unlocked, wireless module is waken up, and carries out data acquisition and transmission.Sampling period is the longest, and the system low-power consumption time is the longest, saves energy the most.
The above, only specific embodiment of the utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
