Abstract
The utility model discloses a novel control device of a solar water heater measuring and controlling instrument. The control device is integrated into an integral circuit board, and comprises a CPU (Central Processing Unit) controller which is connected with an LED multi-color display circuit, a voltage detection circuit, a key detection circuit, an electric leakage detection circuit and a temperature and water level measuring circuit, wherein the temperature and water level measuring circuit is connected with a sensor through a two-wire and four-wire compatible interface. The novel control device can be compatible with ordinary commercially-available two-wire and four-wire water temperature and water level sensors in an automatic identifying way without requiring any other setting operation, so that a user can replace the sensor conveniently without worrying about matching of a purchased sensor with the measuring and controlling instrument; and elements which are required to be partitioned into two circuit boards originally are integrated onto one circuit board, so that great convenience is brought to work such as production assembly, maintenance, installation and the like.
Description
Technical field:
The utility model relates to a kind of solar water heater measurement and control instrument, and is especially relevant with a kind of new control device of solar water heater measurement and control instrument.
Background technology:
Under the industry background that country saves energy and reduce the cost, the solar water heater industry of China just develops at expansion type.Present increasing family installs and uses solar water heater.The solar water heater measurement and control instrument can be measured the water-temperature water-level of water heater, is water on the water tank automatically, under the not enough situation of water temperature, heats for water tank automatically.So there is the family that solar water heater is installed all can select to increase now the solar water heater measurement and control instrument is installed.
Present solar water heater measurement and control instrument on the market is most because device area is bigger, so the project organization that uses power panel to separate with control panel had so both increased production cost, maintenance and installation is inconvenient again; Aspect the LED demonstration, product on the market uses solid color to show mostly, seems that color is single inflexible; Aspect sensor compatible, most products can only select a kind of installation between the sensor of two wires or four lines, and promptly enabling compatible two kinds also is to be provided with or to use specific control chip in addition.
The utility model content:
The utility model purpose is to solve above problem, provides a kind of adaptation different tame reload requests, low, the convenient production installation and maintenance of production cost, the viewability of increase product, the new control device that has more the solar water heater measurement and control instrument of modern sense bright in luster.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
The new control device of solar water heater measurement and control instrument, the circuit board of described integrating of control device comprises: cpu controller; It connects the colorful display circuit of LED respectively; Voltage detecting circuit, key press detecting circuit, electric-leakage detection circuit; Temperature level measuring circuit, described temperature level measuring circuit connects sensor through the interface of two wires and four-wire compatible.
Adopt technique scheme, the utility model can be discerned compatible general on the market two wires and four line water-temperature water-level sensors automatically, and does not need other any setting operations.Make things convenient for user's emat sensor and need not to worry that sensor and the measurement and control instrument bought do not match more voluntarily.LED adopts high pin LED, below devices such as relay are covered, has promptly saved circuit board space, and is elegant in appearance again; Thereby can the element that need be divided into two circuit boards originally be focused on the circuit board, for work such as production assembling, maintenance, installation bring very big convenience.LED has adopted three kinds of colors of RGB to show, has abandoned monochromatic LED commonly used on the market, lets measurement and control instrument seem that color is more bright-coloured, be more suitable for modern house.Reach save production cost, convenient production installation and maintenance, increase the viewability of product, the purpose that has more modern sense bright in luster.
Description of drawings:
Below with accompanying drawing the utility model is specified:
Fig. 1 is the utility model structural representation;
Fig. 2 is the circuit connecting relation sketch map of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is detailed:
Like the embodiment of Fig. 1, the utility model shown in Figure 2, the new control device of solar water heater measurement and control instrument, the circuit board of described integrating of control device; Comprise: cpu controller 1, it connects the colorful display circuit 2 of LED, voltage detecting circuit 5 respectively; Key press detecting circuit 3; Electric-leakage detection circuit 6, temperature level measuring circuit 4, described temperature level measuring 4 circuit connect sensor 7 through the interface of two wires and four-wire compatible.
The utility model can be discerned compatible general on the market two wires and four line water-temperature water-level sensors automatically, and does not need other any setting operations.Make things convenient for user's emat sensor and need not to worry that sensor and the measurement and control instrument bought do not match more voluntarily.LED adopts high pin LED, below devices such as relay are covered, has promptly saved circuit board space, and is elegant in appearance again; Thereby can the element that need be divided into two circuit boards originally be focused on the circuit board, for work such as production assembling, maintenance, installation bring very big convenience.LED has adopted three kinds of colors of RGB to show, has abandoned monochromatic LED commonly used on the market, lets measurement and control instrument seem that color is more bright-coloured, be more suitable for modern house.Reach save production cost, convenient production installation and maintenance, increase the viewability of product, the purpose that has more modern sense bright in luster.
The above only is the preferred embodiment of the utility model, so all according to the described structure of the utility model patent claim, the equivalence that characteristic and principle are done changes or modifies, and includes in the utility model patent claim.
