Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, a kind of reservoir level remote supervision system, comprise: central processing unit, level sensor, power module, communication module, described power module comprises power supply and feed circuit, power supply is connected to central processing unit, level sensor, communication module by feed circuit, described level sensor is connected to central processing unit by A/D change-over circuit, amplifier is provided with between A/D change-over circuit and level sensor, be provided with real time clock circuit between A/D change-over circuit and central processing unit, central processing unit is also connected with communication module.
Described level sensor adopts piezoelectric sensor, and in piezoelectric sensor, the main piezoelectric used includes quartz, sodium potassium tartrate tetrahydrate and phosphoric acid dihydro amine.Wherein quartz (silicon dioxide) is a kind of mineral crystal, piezoelectric effect finds in this crystal, within certain temperature range, piezoelectric properties exist always, but after temperature exceedes this scope, piezoelectric properties disappear completely (this high temperature is exactly so-called " Curie point ").Due to along with stress changing electric field change small (also just saying that piezoelectric modulus is lower), so quartz gradually substitute by other piezoelectric crystal.And sodium potassium tartrate tetrahydrate has very large piezoelectric susceptibility and piezoelectric modulus, but it can only apply under room temperature and the lower environment of humidity ratio.Phosphoric acid dihydro amine belongs to artificial crystal, can bear high temperature and quite high humidity, so be widely used.
Described central processing unit adopts AT89C51, AT89C51 is a kind of low-voltage of band 4K byte flicker programmable and erasable ROM (read-only memory) (FPEROM-Flash Programmable and ErasableRead Only Memory), high-performance CMOS 8-bit microprocessor.This device adopts ATMEL high density nonvolatile memory manufacturing technology to manufacture, with the MCS-51 instruction set of industrial standard and output pin mutually compatible.
Described A/D change-over circuit employing TLC2543 is 12 bit serial analog to digital converters of TI company, uses switching capacity Approach by inchmeal technology to complete A/D transfer process.Owing to being serial input structure, 51 series monolithic I/O resources can be saved; And moderate, resolution is higher, therefore has in instrument and meter and applies comparatively widely.
Described communication module adopts MC55 chip, and this wireless module is three frequency modules that on current market, size is minimum.The end to end connection device of MC55 is connected to chip application platform by the pin that 50 pin 0.5mm are wide.50 pins, for controlling each logical block, transmit data and sound signal, and supply power provide queue.MC55 functionally sees primarily of four parts formations: GSM baseband processor, GSM radio frequency part, power unit and FLASH memory.There are two lack of balance asynchronous serial ports (ASC0, ASCl), can transmitted in both directions AT instruction and data, data-interface is configured to 8 bit data positions and 1 position of rest, and no parity check position, works in CMOS level.
The utility model system can timing acquiring waterlevel data, and to be converted to by waterlevel data after voltage data is transferred to single-chip microcomputer at sensor, single-chip microcomputer needs to process data be reduced into waterlevel data and send.Master routine, never stops, until power down from start just in continual circulation.Program can not be stopped in various piece and be waited for the result of certain part, but continues to run until next circulation inquires about whether obtain accordingly result again, is then process at once, otherwise continues circulation.This operating mechanism ensure that program performs accurately and reliably, especially for the system needing periodic samples.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
