Abstract
A two-line type water level controller comprises a water level detecting unit for water towers, a signal transformation unit, a two-line transmission unit, a main control unit, a water pump control unit, a water pump interface unit, an alternating current input unit and a direct current supply unit. The two-line type water level controller is characterized in that the water level detecting unit for water towers is connected with the signal transformation unit; and the output of the alternating current input unit is divided into two ways, wherein one way is connected with the main control unit through the direct current supply unit, and the other way is connected with the water pump interface unit through the water pump control unit. The water level detecting unit for collecting water level signals inside the water towers is connected with the input end of the main control unit through the signal transformation unit and the two-line transmission unit. The output end of the main control unit is connected with the water pump interface unit through the water pump control unit. The water level controller has a simple and compact structure, low cost, easy operation and stable and reliable performance and is capable of being assembled easily and transmitting signals by two lines.
Description
Technical field
The utility model relates to a kind of Level Control of Water Towers device, refers in particular to a kind of twin wire water level controller.
Background technology
Water level controller is a kind of rural area and city secondary water-supply control device of being widely used in, and the Level Control of Water Towers device mainly contains float-ball type, Weight type, electromechanical, electronic type etc. at present.Wherein electronic type is commonplace in actual applications.Common electronic type water level controller, its one-piece construction are complicated, comprise transformer, auxiliary reclay, A.C. contactor, water level detection part and control circuit etc.Exist inlet wire, outlet many, and no-load power consumption big, install complicated, safeguard difficult, the life-span is short, use problems such as inconvenience.Common water level controller adopts three signal wires to finish the signal transmission mostly, and inconvenience is installed, and is difficult to promote.Thereby design the water level controller that a kind of employing two lines come transmission signals, and not only save line, the convenient installation also realized water level detecting accurately and reliably simultaneously.
The utility model content
The purpose of this utility model is to overcome the problem that prior art exists and a kind of simple in structure, with low cost, reliable and stable, twin wire water level controller of being convenient to install is provided.
The utility model is to adopt following proposal to realize: the twin wire water level controller, comprise water tower level detecting unit, signal conversion unit, two line transmission units, main control unit, water pump control module, water pump interface unit, AC input cell, dc power supply unit, it is characterized in that: described water tower level detecting unit links to each other with signal conversion unit; The output of described AC input cell divides two-way, and the dc power supply unit of leading up to links to each other with main control unit, and another road links to each other with the water pump interface unit by the water pump control module.The water level detecting unit that is used for gathering water tower middle water level signal links to each other with the main control unit input end through signal conversion unit, two line transmission units, and the output terminal of main control unit links to each other with the water pump interface unit by the water pump control module.
Principle of work of the present utility model is summarized as follows: be positioned over level sensor in the water tower and do not detect when having the full signal of water or water in the water tower and utilize two line transmission units to deliver to main control unit by signal conversion unit, main control unit does not output a control signal to the opening and closing of water pump control module control water pump according to having water, water to expire after signal compares analysis, thereby has realized that the water level in the water tower remains between the peak level and lowest water level of setting.The utility model adopts two lines to come the water level controller of transmission signals, not only saves link material, and convenient the installation also realized water level detecting accurately and reliably simultaneously.In sum: the utlity model has advantage of installing simple and compact for structure, with low cost, reliable and stable, convenient.
