Specific implementation mode
The present invention is described in further detail with reference to the accompanying drawings of the specification:
The present invention relates to a kind of water paddy irrigation water effective utilization coefficients Auto-Test Systems for miniature irrigation area, including set
It sets and acquires sub-control system, data acquisition master control system and pc client, sensor and data acquisition in the sensor in farmland, data
Sub-control system is connected, and data acquire sub-control system and send data to data acquisition master control system, data by radio frequency network
Acquisition master control system sends data to PC machine client by gsm module.As shown in Figure 1, the sensor includes field water
Level sensor, soil humidity sensor, channel water level sensor, the water level and soil moisture data that sensor measurement obtains pass through
Wireless data transmission module sends data acquisition master control system to, and data acquisition master control system leads to the data being aggregated into and this point data
It crosses gsm module and sends Terminal Server Client to.System uses MSP430 super low power consuming single chip processors, and additional hardware timer wakes up and item
Part, which wakes up, realizes suspend mode, wake-up states switching.When water level reaches given threshold, triggering master control system work, all sub-control systems
For system by synchronized wake-up, sub-control system carries out sampling or suspend mode program under the control of master control system.Sub-control system and master control system
Principle it is as shown in Figures 2 and 3, sub-control system includes CPU, on CPU connect flash chip, AD conversion module, communication management
Module and power module, AD conversion module connect sensor, and communication management module connects radiofrequency emitting module, also set on CPU
Set power supply sleep management module, power module includes solar cell and rechargeable lithium battary, solar cell and lithium battery
It is connected in charge management module, it is system power supply usually to rely on solar energy, while solar cell can also carry out lithium battery
Charging, when no sunlight irradiates, system relies on lithium battery power supply.Master control system includes equally CPU, is connected on CPU
Flash chip, communication management module and power module are connect, the difference is that communication management module connection radiofrequency emitting module and and PC
The GSM transmitting modules of main-machine communication.The wake-up of master control system and sub-control system is all made of hardware timer wake-up, avoids with single
Easily there is the problem of program fleet in itself timing routine wake-up of piece machine.Hardware timer wake-up circuit is as shown in Fig. 4, integrates electricity
Road U1 is CMOS integrated circuit CD4060, coordinates the crystal oscillator of 32.768KHz, exports 2Hz pulses in frequency dividing end Q14, is sent to next
A integrated circuit U2, is further divided, at the end Q9, Q10, Q11, Q12, Q13, Q14 of U2, respectively export the period be 64 seconds,
128 seconds, 256 seconds, 1024 seconds, 2048 seconds square waves.Metal-oxide-semiconductor V2, realization is driven to power on again with the driving of this square wave metal-oxide-semiconductor V1, V1
Control.V2 uses the switch metal-oxide-semiconductor APM4953 of low internal resistance, when conducting there was only 0.08 Ω, hardly pressure drop is brought to be lost.Wire jumper
J1 is used for square wave frequency selected to use.If daily sampling frequency be twice, between be divided into 12 hours, most using foregoing circuit
It is divided into waking up certainly the time for 2048s between length, inquired first by SCM program from after waking up and records from awake number, when counting reaches
At 12h/2048s=21 times, just starts and sample primary.If increasing acquisition frequency, as long as the counting decision content of reprogramming
.When field adjustable, wire jumper J1 can be used to change Wakeup interval, such as Wakeup interval 64s, the sampling period becomes about 22
Minute, facilitate field adjustable and observation data acquisition situation.
When data acquisition is completed to need suspend mode, a high level is provided by microcontroller control and is sent to integrated circuit U1 and U2
RST reset terminals on, so that whole outputs of U1 and U2 is all become low level, the therefore all cut-offs of field-effect tube V1, V2 are all to adopt
The power supply of sample circuit stops.Since U1 and U2 is to restart to count from zero after reset, so timing also restarts from zero, etc.
It waits for the arrival of square wave next time, starts a new power up cycle.The Q14 feet of U1 are connected to a light emitting diode, with 2Hz
Frequency scintillation, be used to refer to the work of oscillator.The differential circuit that R1 and C1 is constituted, the signal of service life 2Hz, in upper jump
Along lighting, to reduce the power consumption of battery.Since cmos circuit has the characteristics that low-power consumption, this partial circuit at work,
The only power consumption of 10uA.
It is synchronous from control of waking up, during work upon awakening, if because certain program fleets or principal point branch it
Between from time irreversibility of waking up, no response can all occur so lead to that principal point continuous Query or branch can not receive sleep command and
It is constantly in working condition.There is such case, this system can work 40 points with self-healing, under the control of U1 and U2
Terminated various mistakes, including crash mistake after clock by forced interruption.This is that the oscillator output square wave formed by U1, U2 determines
, at the end of 40 minutes high level, enters low level state naturally and realize power-off.Go out if it is during work upon awakening
Existing program fleet or branch do not have response, and the timings in 40 minutes for being not necessary to waiting timer terminate, under the control of sleep command,
Order is sent out by principal point CPU, U1, U2 is made to reset, is re-powered after realizing power-off.
