Embodiment
As shown in Fig. 1 ~ Fig. 5, the removable LED hydrologic monitoring system of integration, comprise the level sensor for detecting the excess surface water degree of depth, described level sensor connects mainboard CPU by RS-485 bus, described mainboard CPU connects LED display by LED drive circuit, described mainboard CPU connects LED alarm lamp by alarm lamp driving circuit, and described LED drive circuit, LED display connect lithium battery by power converting circuit.Described level sensor is YLN-Z1058T type throw-in type level sensor.
As shown in Figure 2, in figure, IC2.IC3 is exactly Three-State driving gate to LED drive circuit figure, for driving LED display screen refresh data.In figure, SPI1_SCK, SPI2_SCK, SPI3_SCK signal is just used to the CPU IO port of simulating LED driver' s timing.
Alarm lamp driving circuit figure as shown in Figure 3, when the water level value that host CPU collects is greater than the alarm water level value of setting, the EX_POWR2 pin of CPU just exports high level, and corresponding EX_FMQ_VCC pin exports 12V power drives alarm lamp, produces sound and light alarm effect.
As shown in Figure 4, Li_Po_Bat is 12V lithium battery source to power converting circuit, LM2678 high efficiency 5A step-down voltage voltage stabilizer.Its inside is integrated with a fixing oscillator, seldom just need only can form a kind of mu balanced circuit efficiently by peripheral components, greatly can reduce the volume of heat radiator, and in most of the cases not need heat radiator; There is perfect protection circuit inside, comprises current limit and Thermal shutdown circuit etc.; 5V power supply supply motherboard circuit is transformed to by inner copped wave concussion.
The utility model system detects the excess surface water degree of depth by YLN-Z1058T type throw-in type level sensor, in system, mainboard CPU sends by RS-485 bus the Modbus order that reads data every 1000 milliseconds, after level sensor receives corresponding director data, verification also, after successfully decoded, returns to mainboard CPU the water level value of correspondence by Modbus bus.Mainboard CPU is when Communications failure, and maximum retry reads water level instruction three times, ensures the integrality of data.After waterlevel data reads and, water level numerical value also just will can be sent in LED display through code conversion and show.Mainboard CPU is built-in with the dot array data of a set of Chinese character and ASC code, and these dot array datas pass through in the FLASH storage space of programmable device programming in CPU when programming.During data conversion, mainboard CPU after reading water level numerical value extracts the ASC of the numerical value of correspondence, by the order at ASC code table, navigates to the dot array data that corresponding A SC numerical value is extracted in corresponding numerical value position.LED display adopts 12 interfaces of market standard, makes numerical monitor in LED display by not stopping scanning dynamically.Mainboard CPU is by arranging the timer that timing is 20ms, and refreshing per second 50 times, this can reduce the flicker of picture.
After mainboard CPU collects water level value, carry out numerical value judgement, as exceed setting alarm water level value after, export high level by an IO pin and drive a power MOS pipe conducting, after metal-oxide-semiconductor conducting, 12V electricity is just carried in the LED alarm lamp on masthead, now LED alarm lamp is lighted, inner 12V motor is also energized rotations, and two reflectors that motor shaft is installed are rotation and then, LED light line reflection is gone out, to reach the visual effect of flicker, to cause the attention of pedestrian.
The mainboard cpu system of the utility model system adopts 32 high-performance arm processor CPU to be core, is read the water level information of throw-in type level sensor collection by 485 communication chips.These two kinds of chips of IC2 (74HC245), IC4 chip (74HC245) are typical CMOS type Three-State gate circuits, for shaping, the amplification of signal.Because the data/address/control bus port of single-chip microcomputer or CPU has certain load capacity, if load exceedes its load capacity, generally driver should be added.) promote LED display show the water level information and some other information that collect.
The utility model system can the tipping-bucket rain-gauge of outside connected switch amount type, is input to CPU external interrupt mouth, carries out the counting of tipping bucket rainfall after signal isolation being amplified by photoelectrical coupler IC6.
The display brightness of the utility model system can the power of environmentally light automatically adjust, this automatic adjustment be according to R7 in circuit the intrinsic standoff ratio of R9 two resistance carry out, in circuit, R9 is one piece of photoresistance, this resistance is assemblied on the transparent window of chassis shell body case, for the change of perception extraneous light.Light is stronger, and the resistance of R9 is larger, and the voltage of PH_AD point is also larger, after CPU detects change in voltage, just regulates the refresh rate of LED display, the luminance adaptation external environment condition of screen is changed.
The utility model system adopts lithium battery power supply, lithium battery is full of electricity at 15.8V, cut-off voltage is at about 11.2V, to point out in LED display when undertension, in circuit, R8/R10 resistance carries out voltage detecting, by the dividing potential drop to cell voltage, the AD acquisition port sending into CPU carries out AD conversion, obtains cell voltage.When CPU runs, thousand magnitudes of voltage of one direct sum setting judge, after being less than settings, just carry out display reminding, electricity is not enough, needs to charge.
In order to adapt to the user demand of different user unit, the utility model Operation system setting serial port module, the renewal carrying out information data arranges use.By host computer, start-up picture and some other prompting text message are arranged.Host computer also can arrange systematic parameter and check.
