Description
Technical field
The utility model relates to a kind of Water-Level Supervising System, specifically SCM Based Water-Level Supervising System.
Background technology
Traditional Water-Level Supervising System, has adopted the method for liquid level machine monitoring substantially.When water level exceedes certain value that liquid level gauge is set, alarm will be triggered, and the monitoring water level of this mode faces several problems:
1. water level approaches alarm value, and alarm does not occur.
2. water level has exceeded alarm value, and alarm occurs, and but can not learn concrete water level value.
3. water level, because environmental factor does not stop to change, cannot judge the current concrete condition of water level.
Utility model content
For the problems referred to above, the utility model proposes a kind of SCM Based Water-Level Supervising System.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of SCM Based Water-Level Supervising System, comprises power supply, also comprises the pressure transducer being connected with power supply, signal amplifier, A/D converter, keyboard, single-chip microcomputer, display, warning horn.Its annexation is: pressure transducer connects the input end of signal amplifier, and the output terminal of signal amplifier connects A/D converter, and A/D converter output terminal connects single-chip microcomputer, keyboard, and display is all connected with microcontroller serial port with warning horn
Compared with prior art, the beneficial effects of the utility model are:
A kind of SCM Based Water-Level Supervising System the utility model proposes has higher sensitivity, can, according to the difference of concrete water level environment, set different alarm values simultaneously, has mobile type.
Accompanying drawing explanation
Shown in Fig. 1, it is the structural representation of this SCM Based water level control supervisory system.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: a kind of SCM Based Water-Level Supervising System, comprise power supply, it is characterized in that: also comprise the pressure transducer being connected with power supply, signal amplifier, A/D converter, keyboard, single-chip microcomputer, display, warning horn, its annexation is: pressure transducer connects the input end of signal amplifier, the output terminal of signal amplifier connects A/D converter, A/D converter output terminal connects single-chip microcomputer, the output terminal of keyboard is connected with single-chip processor i/o serial ports, the input end of display is connected with single-chip processor i/o serial ports, the input end of warning horn is connected with single-chip processor i/o serial ports.
Described pressure transducer is long strip type, water level is when the different position of pressure transducer, and the pressure that pressure transducer is subject to is also inconsistent, simultaneously, if the pressure of pressure transducer output, in change procedure, can judge by the data of output the present case of water level.
Described single-chip microcomputer is selected STC89C52 single-chip microcomputer, inputs water level alarm value by keyboard in single-chip microcomputer, and single-chip microcomputer calculates water level value corresponding to this force value by the force value that completes A/D conversion receiving, and with the comparison of water level alarm value.If the water level value drawing is less than, approach alarm value, send primary alarm, if water level value has exceeded water level alarm value, send second-level alarm, if the water level value drawing increases always, send three grades of alarms.
