Specific embodiment

Specific embodiment of the present utility model is described in further detail below.

Color lamp water circulation system Intelligent anti-freezing control circuit described in the utility model, applied to color lamp water as shown in Figure 3 It further include being connected to high-order pipeline and low including water pump and the low level pipeline being connect with water pump and high-order pipeline in the circulatory system Anti-icing fluid add-on system between the pipeline of position, the anti-icing fluid add-on system includes blending tank, at the top of the blending tank with it is described High-order pipeline connection, the blending tank top are also connected with anti-icing fluid supplement pipe and water supply pipe, the anti-icing fluid supplement pipe and benefit The first solenoid valve and second solenoid valve are respectively arranged on water pipe, it is vertical to be connected between high-order pipeline below the blending tank The pressure measuring tube of setting, the pressure measurement bottom of the tube are connected with pressure sensor；The water circulation system further includes measurement The temperature sensor of water temperature and the liquid level sensor for checking water level inside.

Above-mentioned temperature sensor, pressure sensor, liquid level sensor and solenoid valve etc. are used as control described in the utility model Signal acquisition in circuit and the component controlled.

Above-mentioned color lamp water circulation system antifreeze based on the principle that antifreezing agent to be added to the antifreezing agent formed in water water-soluble The freezing point of liquid is related to solution concentration, and solution concentration determines the density of aqueous solution, by detecting solution density, can obtain Antifreeze concentration into aqueous solution increases antifreeze concentration according to detection density, can reduce water to obtain freezing point at this time The freezing point of solution.

The water flow of normal circulation generates power by water pump, by low level pipeline, high-order pipeline, water pump and anti-icing fluid addition It is flowed on the water flow circuits of system composition.

The pressure sensor signal of pressure measurement bottom of the tube setting as shown in Figure 1 is tested and analyzed by control circuit, and is pressed Power is proportional to solution density, i.e. the signal of pressure sensor transmitting is practical to characterize solution density, and control circuit can be using such as Under the first logic control mode, realize that the physical circuit of which is as shown in Figure 1.

If finding that temperature sensor detects that temperature is below or near to freezing point temperature simultaneously, and density is lower than threshold value, then Control system controls the first solenoid valve and opens, and starts to fill anti-icing fluid, anti-icing fluid is uniformly mixed by blending tank with water, at this time water Solution density rises, until density rises to higher than threshold value, then control system closes the first solenoid valve.If temperature raising or dense Degree is higher than threshold value, then can close the first solenoid valve.

If liquid level sensor discovery needs to beat since aqueous solution volatilization leads to water shortage in entire water-flow circuit It opens second solenoid valve and carries out moisturizing, individually carrying out water-refilling operation necessarily causes to decline in antifreezing agent solution concentration, therefore can be When detecting temperature below or near to freezing point temperature, carry out opening the first solenoid valve progress antifreezing agent while water-refilling operation at this time Supplement can make the supplement speed of antifreezing agent and the benefit of water by the pipeline for selecting the solenoid valve or caliber of different size different It is appropriate to fill speed proportional, not only will not excess inject antifreezing agent, but also will not make moisturizing that antifreeze concentration be caused to decline rapidly.

It is that high level is effective in each sensor output signal, that is, exports high level signal, control system when being higher than threshold value The above-mentioned control mode of system can realize that the control is that circuit includes first and door using control system as shown in Figure 2, the Two pass through converter connection first and door with door and/or door, the output end of the temperature sensor and pressure sensor respectively The output end of two input terminals, the temperature sensor and liquid level sensor passes through converter connection second and the two of door respectively A input terminal, two with the output end of door respectively with or two input terminals of door connect, described or door output end and described the The output end of the connection of one solenoid valve control, the liquid level sensor is connected by converter and second solenoid valve control.

Converter is used to convert the analog signal of each sensor to the digital level that can be identified by digital logic gate Signal realizes temperature detection and Density Detection with door, and temperature detection and water trigger logic while detection, and foregoing circuit can To realize the first previously described control mode, when carrying out water-refilling operation, only can just be prevented simultaneously under low-temperature condition Freeze the complement operation of agent.

In another specific embodiment of the control circuit as shown in Figure 2, provide it is a kind of for low temperature more preferably The mode of make-up solution, for the form using storage tank in Fig. 3, as shown in figure 3, in the mixing pot bottom and low level pipeline Between be connected with storage tank, third solenoid valve is provided between the storage tank and low level pipeline, in the control system and Fig. 1 Third solenoid valve control connection.

The make-up solution under low-temperature condition can prestore the antifreeze solution for the ratio of having regulated using storage tank, Water level preferentially supplements antifreeze solution when reducing from storage tank, so that direct moisturizing and antifreeze be avoided to cause whole solution concentration Decline.

The difference of second of control mode and the first control mode is: when low temperature and liquid level is lower requires supplementation with When, it opens third solenoid valve and is directly supplemented to low level pipeline, open simultaneously the first solenoid valve and second solenoid valve starts to circulation System supplement.When liquid level is lower but is not in low-temperature condition, then opens second solenoid valve and carry out simple water-refilling operation.

The control system of second of control mode can be achieved as shown in Fig. 2, but output signal essentially identical with Fig. 1 connect pass System is different, including first and door, and second passes through respectively with door and/or door, the output end of the temperature sensor and pressure sensor The output end of two input terminals of converter connection first and door, the temperature sensor and liquid level sensor passes through AD respectively Converter connection second and two input terminals of door, two with the output end of door respectively with or two input terminals of door connect, institute It states or the output end of door is connect with first solenoid valve control, the described second output end with door and the third solenoid valve control The output end of system connection, the liquid level sensor is connected by converter and second solenoid valve control.

In circuit specific embodiment shown in Fig. 1 and 2, alarm signal W can also be exported, it can be with color lamp shown in Fig. 3 Alarm device is installed in water circulation system and heater, the heater are mounted on pipeline and/or valve, the heater and police It reports the output end of device and timer to control to connect.Mainly for due in anti-icing fluid bottle 4 antifreezing agent prestore insufficient or the first electromagnetism Although the blocking of valve failure or pipeline are endured cold, blocking causes control system to issue the instruction that the first solenoid valve is opened, without enough anti- Freeze the case where agent is added.

Control circuit uses circuit as shown in Figure 1 or 2 at this time, using timer to the opening time of the first solenoid valve It is detected, timer itself can set a monitoring duration, such as 300 seconds, after 300 seconds, density detector detected value It still is below threshold value, then cannot issue reset signal, timer exports alarm signal at this time, while starting heating device, such as The heater strip 11 wound on low level pipeline shown in Fig. 3, avoids water flow from freezing, if density detector monitors to be higher than threshold value, Then output reset signal, timer time zero, no longer output alarm and starting heating function.
