Embodiment
In FIG, this practicality relates to a kind of sensor, more specifically to a kind of soil temperature sensor, comprise temperature-sensing probe I, temperature-sensing probe II, become and send plate, toggle switch, power supply I, single-chip microcomputer, RS232 interface, hummer and power supply II, spot measurement and multilayer measurement can be carried out to the soil moisture, reduce the impact of the factors such as structure, encapsulation and metering system, and there is warning function.
Temperature-sensing probe I, for carrying out single-point detection to the soil moisture, is responded to temperature in soil and temperature signal is converted into current signal and transmit.The temperature-sensing probe that temperature-sensing probe I selects Ya De promise Semiconductor Co., Ltd to produce, its model is ADT7420.The measuring accuracy of ADT7420 temperature-sensing probe is lower, when carrying out spot measurement to the soil moisture and required measuring accuracy is less demanding, utilize ADT7420 temperature-sensing probe to carry out the collection of temperature signal, the temperature signal that ADT7420 temperature-sensing probe collects is converted to corresponding current signal transfer and send plate to becoming.
Temperature-sensing probe II transmits for responding to temperature in soil and temperature signal being converted into current signal.The sensor that temperature-sensing probe II selects Mei Xin Semiconductor Co., Ltd to produce, its model is DS18B20.The measuring accuracy of DS18B20 temperature-sensing probe is higher, when needs carry out multilayer measurement to the soil moisture and measuring accuracy requires high, selects DS18B20 temperature-sensing probe to carry out the collection of temperature signal.Temperature signal is converted to current signal transfer and send plate to becoming by DS18B20 temperature-sensing probe.
Toggle switch is as becoming the switch sending board parameter to arrange.Stir toggle switch, then people can send plate to arrange to change, to switch the duty of ADT7420 and DS18B20.Stir toggle switch, people, to becoming the short circuit and open fault setting of sending plate to carry out temperature-sensing probe I and temperature-sensing probe II, when corresponding failure appears in temperature-sensing probe I, temperature-sensing probe II, become after sending plate will process signal and send alerting signal to single-chip microcomputer.
Power supply I send plate to power for change.Become and send plate to provide operating voltage into temperature-sensing probe I and temperature-sensing probe II, carry out to the received signal changing and sending out simultaneously.Become the change sending plate to select company limited of peace Germany and Britain to produce and send plate, its model is AD100.AD100 change exports the current signal of 4 to 20MA after sending plate to carry out linearization process to the received signal.Utilize AD100 to become and send plate that surge and voltage also can be prevented along becoming, prevent temperature-sensing probe I and temperature-sensing probe II are subject to high-voltage impact and damage.
Single-chip microcomputer is used for Received signal strength and exports steering order after processing signal.Single-chip microcomputer select Philips Radio&Video Co. to produce single-chip microcomputer, its model is 80C552.RS232 interface for connecting peripheral hardware, so that data are transmitted remote port.Hummer receives the drive singal sounding of single-chip microcomputer.Power supply II is powered for single-chip microcomputer.80C552 single-chip microcomputer receives the temperature signal becoming and send plate to transmit, and after processing temperature signal, signal is transferred to peripheral hardware through RS232 interface.When temperature is reduced to the limit value of single-chip microcomputer, single-chip microcomputer Received signal strength also drives hummer sounding alarm, reminds relevant staff to process, and simultaneously alerting signal is transferred to peripheral hardware through RS232 interface and shows by single-chip microcomputer.
Certain above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing; the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belong to protection domain of the present utility model.
