Embodiment
Below in conjunction with accompanying drawing, the technical scheme of invention is elaborated:
In swimming pool temperature of the present utility model and liquid level monitoring and alarm, first, second single-chip microcomputer all selects STC89C51 single-chip microcomputer as controller, controls water temperature and liquid level, and can alarm liquid level and alarm temperature.
As shown in Figure 1 and Figure 2, this device comprises host computer and slave computer, slave computer comprises power module, temperature collect module, liquid level acquisition module, the first single-chip microcomputer, LCD display module, temperature control modules, liquid level warning module and the first wireless module, described power module, temperature collect module, liquid level acquisition module are connected with the first single-chip microcomputer, the output terminal of the first single-chip microcomputer is connected with the input port of LCD display module, temperature control modules, liquid level warning module, and the first wireless module is connected with the first single-chip microcomputer by communication interface circuit; Host computer comprises second singlechip, keyboard circuit, the second wireless module and liquid crystal display circuit composition, the output terminal of second singlechip is connected with the input end of liquid crystal display circuit, the output of keyboard circuit is connected with second singlechip input interface, and the second wireless module is connected with second singlechip by communication interface circuit; Upper with and slave computer communicate to connect by first, second wireless module.
Temperature collect module adopts digital temperature sensor DS18B20 to be used for collecting temperature signal, and its volume is little, and precision is high, is suitable for voltage wide, and antijamming capability is strong.The rotation of two motors of Control, correspondence is controlled hot water valve and cold valves respectively, thereby realizes the real-time control of water temperature.Liquid level acquisition module adopts wireless ball float water level sensor, and the voltage signal that the temperature signal detecting and liquid level signal is converted to standard is input to A/D interface change-over circuit; The digital signal of A/D interface change-over circuit output enters the first single-chip microcomputer; The first single-chip microcomputer compares then pilot relay according to the signal of the digital signal of input and setting and exports corresponding signal, the demonstration of go forward side by side trip temperature and liquid level.
Power module provides electric energy for whole system; In native system, will adopt intelligent temperature sensor.Its major advantage is to adopt digitizing technique, can directly export in digital form dut temperature value, has that temperature measurement error is little, resolving power is high, antijamming capability is strong.Can remote transmission data, user can design temperature upper and lower limit, there is out-of-limit auto-alarm function, carry the advantages such as serial bus interface, adaptive various microcontrollers, containing microprocessor and single-chip microcomputer, it is the requisite core devices of temperature control system of new generation that development and exploitation have high performance-price ratio.
What native system temperature collect module adopted is the DS1820 type single line intelligent temperature sensor of being produced by DALLAS semiconductor company of the U.S., belong to the intelligent temperature sensor of adapt trickle processor of new generation, can be widely used in temperature survey and the control instrument in industry, the field such as civilian, military, in TT&C system and main equipment.The surrounding that liquid level is captured in swimming pool is respectively put four contacts, in the time that water level reaches contact, just sends a signal to single-chip microcomputer.The advantage of this mode is highly sensitive, and circuit is simple, convenient and swift.
For making the human-computer interaction interface of system better, liquid level warning module is provided with two-way alerting signal, is respectively the light emitting diode of two-way redness, for showing off-limit alarm and erroneous input warning.The ceiling temperature setting higher than staff when water temperature or lower than set lower limit temperature time, think to have occurred out-of-limitly, off-limit alarm lamp (LED1) is lighted, having there is off-limit alarm in prompting operation, reminds staff to note.In the time that swimming pool temperature starts to rise from low temperature, all can there is off-limit alarm to system before lower limit temperature.In the time there is off-limit alarm, staff should note being this kind of situation, and this situation can be ignored.Erroneous input report to the police (LED2) be mainly used in Keyboard management, if in the time carrying out constant temperature setting, upper and lower limit Temperature Setting with keyboard staff by desired step in explanation, to operate be not exactly so-called maloperation.In the time there is maloperation, erroneous input alarm lamp is lighted, and now staff should carry out input checking, checks and illustrates and correct.Off-limit alarm and erroneous input are reported to the police and are drawn by P2.5 and the P2.6 mouth of the first single-chip microcomputer respectively, and the resistance connecing on it is current-limiting resistance, for preventing that electric current light emitting diode excessive and that cause from burning.Liquid level is that wireless ball float water level sensor detects by liquid level acquisition module, then adopts LCD dynamically to show water temperature, starts immediately pit alert system once exceed the liquid level of setting.
