Fig. 2 is that native system is arranged on the structural representation on flowerpot.

In figure: 1-single-chip microcomputer; 2-key-press module; 3-clock module; 4-power supply; 5-pressure transducer; 6-display module; 7-relay; 8-flowerpot; 9-water pipe; 10-chassis; 11-reseting module.

Embodiment

As illustrated in fig. 1 and 2, the SCM Based intelligent flower watering system of the utility model, comprises pressure transducer 5, single-chip microcomputer 1, power supply 4, relay 7, display module 6, clock module 3, reseting module 11 and key-press module 2; Pressure transducer 5, power supply 4, relay 7, display module 6, clock module 3, reseting module 11 and key-press module 2 are all connected with single-chip microcomputer 1.

Single-chip microcomputer 1 adopts AT89S52 single-chip microcomputer.AT89S52 is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontrollers, has 8K at system programmable Flash storer.Use the manufacture of Atmel company high-density nonvolatile memory technology, completely compatible with the instruction of industrial 80C51 product and pin.On sheet, Flash allows program storage at system programmable, is also suitable for conventional programming device.On single-chip, have 8 dexterous bit CPUs and at system programmable Flash, AT89S52 is used widely in numerous embedded Control application systems.

Pressure transducer 5 has several, the ASDX series pressure transducer of employing.ASDX series is a kind of enhancement mode kind of the ICT representative products of Sensym company assay approval, is also a kind of SDX series sensor that industrial level is leading.The physical dimension of enhancement mode ASDX sensor is slightly larger than SDX, can provide the output voltage of high level (4.0 V measurement range), low price.This series is used an ASIC who is arranged on circuit board to calibrate completely and temperature compensation.This class sensor is applicable in the non-ionic working fluid of non-aggressive as in air and dry gas.Sensor can be used for measuring absolute value differences and manometric pressure limit from 1 psi (ASDX01DN) to 100 psi (ASDX100).Absolute pressure sensor has an inner vacuum reference, and its output voltage is directly proportional to absolute pressure.Differential pressure pick-up allows pressure to be applied to the both sides of detecting diaphragm, can be used in the measurement of tensimeter or differential pressure.The precision of all ASDX series pressure transducers is all in ± 2.0%.
