Abstract
The utility model provides a water level and precipitation rain fall data collector. The collector is composed of a shell, a water level and precipitation rain fall collector interface on the shell, a RS-232 interface, a telephone interface, a display screen, a keyboard, an inside power supply, a MODEM, singlechips, a clock and a memorizer. As the double singlechips have respective responsibility, and the 6V power supply to supply power and reasonable method of voltage reduction and rise are adopted, the collector shows obvious effects in energy saving and consumption reducing; and as a telephone wire energy conversion device is added, a 6V / 4A accumulator can supply power for over 6 months; in addition, a watchdog is arranged in a CPU-2, the capacity of the interference resistance of the colletor can be monitored in the real-time and improved, thereby the system has higher reliability.
Description
The utility model relates to a kind of water level, rainfall data collector, belongs to the water conservancy monitoring instrument, is particularly suitable for the monitoring of water level, rainfall.
A kind of water level, rainfall data collector generally all is placed on the field, there is the remote data transmission, long-time storage etc., power supply inconvenience simultaneously, the basic storage battery power supply that adopts, this just requires instrument is the low-power consumption type, to prolong the power-on time of battery, and the 12V storage battery power supply is all adopted in the udometric data acquisition of existing water level, the normal voltage of 12V accumulator is 11.6～14V, and the display screen of instrument internal, clock, the RS232 interface, the water level interface, the rainfall acquisition interface, CPU, storeies etc. generally all are the 5V power supply, having only the water level acquisition interface is the 12V power supply, and promptly the operating voltage of most device is 5V; And with the water level acquisition device of water level acquisition interface, only adopt the 12V power supply,, the bigger energy of loss as if being the power supply of 5V voltage with the 12V power source conversion in the moment of image data (acquisition time is less than 30Ms); Simultaneously a large amount of the employing is single CPU control, and its less stable, energy consumption are also bigger, as Chinese patent 00237501.X etc. above-mentioned shortcoming arranged all.
The purpose of this utility model provides a kind of water level, the rainfall data collector that a kind of energy consumption is low and stable performance is good.
The purpose of this utility model realizes as follows: a kind of water level, rainfall data collector is by housing and be fixed on water level acquisition device interface (17) on the housing, rainfall collector interface (18), RS-232 interface (11), telephony interface (19), display screen (9), keyboard (8), and inner power supply, MODEM (12), single-chip microcomputer, clock (10), storer (15,16) constitute, MODEM is provided with telephone line interface (19), water level acquisition device interface, rainfall collector interface, RS-232 interface, display screen, clock, keyboard, power supply, MODEM, storer all links with single-chip microcomputer, power supply and water level acquisition device interface, rainfall collector interface, display screen, clock, MODEM, storer links; It is characterized in that: single-chip microcomputer has 2, the CPU-1 of one (13) is system's control, the CPU of rainfall counting and power management, its CPU-2 of two (14) handles CPU for high-speed data, CPU-1 plays supervisory function bit to CPU-2, power supply adopts the 6V accumulator, power after DC-DC voltage changer (3) conversion of water level acquisition device interface employing 6V commentaries on classics 12V, CPU-2, storer (15,16), rainfall collector interface (18), clock (10), display screen (9), RS-232 interface (11), MODEM (12) all adopts through the power supply of the DC power supply after the 5V voltage stabilizing (2), and CPU-1 (13) adopts the DC power supply power supply after the 3.3V voltage stabilizing (1); Through the DC power supply behind the 5V voltage stabilizer, under CPU-1 (13) control, supply with through power control circuit; Keyboard (8), RS-232 interface (11), display screen (9) all link with CPU-1 (13), CPU-2 (14), and storer is subjected to CPU-2 (14) control, and CPU-1 (13) is also controlling rainfall collector interface (18).
Above-mentioned a kind of water level, rainfall data collector is characterized in that also being provided with at the telephone line interface place telephone wire energy converter (7), its two ends respectively with the linking of telephone connection mouth and 6V accumulator.
Above-mentioned a kind of water level, rainfall data collector is characterized in that CPU-2 is connected with a supply voltage pick-up unit.
In conjunction with the accompanying drawings and embodiments the utility model is described further.
