Abstract
The indoor heating temperature control equipoment includes chip micro processor. LCD, miniature printer, signal line, digital temp. sensor, electrically-operated ball valve and drive circuit. At the same time, it is equipped with telephone interface and temp. alarm, fault diagnosis, fault location and pipeline deicing and block-resisting programs.
Description
The present invention relates to a kind of control device, specifically a kind of room heater attemperating unit.
According to the knowledge of the applicant, China's heat supply in winter facility mainly is made up of radiator and caliduct at present, has ball valve or gate valve on the radiator.The adjusting of repairing inspection and heat of radiator all is that manual artificially ball valve is realized.The indoor temperature height is turned off valve; Indoor temperature is low, opens valve.If people forget or have little time manually-operated gate that the non-heat of indoor temperature is promptly cold.The frequent switch of valve is easy to damage, and causes damage, and operating not only bothers but also inconvenient.
Order of the present invention is exactly in order to overcome the deficiency of above-mentioned prior art, provide a kind of safe and reliable, cost is low, easy to use, can realize time opening, close, multi-functional room heater attemperating unit such as adjusting.
For achieving the above object, a kind of room heater attemperating unit of the present invention, it comprises single-chip microcomputer, LCD, mini-printer, holding wire, digital temperature sensor, electric-controlled ball valve, it is characterized in that it also is provided with drive circuit, this circuitous resistance R2 and capacitor C 1 series connection back are in parallel with resistance R 3, the colelctor electrode of transistor T 1 is connected to the intermediate connection point of resistance R 2 and capacitor C 1, the base stage of transistor T 1 and T2 couples together by resistance R 5 and resistance R 4 respectively, resistance R 3 one terminations+5V, a terminated signal lines.
The present invention is energy-conservation, safety, and cost is low, and is easy for installation, the unfailing performance height.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structured flowchart of the present invention.Fig. 2 is the circuit diagram of drive circuit of the present invention.
As can be seen from Figure 1, a kind of room heater attemperating unit of the present invention, it comprises single-chip microcomputer, button, LCD, mini-printer, holding wire, digital temperature sensor, electric-controlled ball valve, drive circuit.Push button signalling is handled by single-chip microcomputer, is transferred to electrically-controlled valve and control device with the command signal form by holding wire.LCD and mini-printer are by Single-chip Controlling, and realization information shows and prints.The feedback information that digital temperature sensor is sensed is given single-chip microcomputer, single-chip microcomputer by setting send instruction by holding wire to electrically-controlled valve and control device, electrically-controlled valve and control device work, working condition is shown by the LCD circulation.Electric-controlled ball valve only need provide when action and not be higher than 48 volts of power supplys, need not power at ordinary times, can keep original state.Electric-controlled ball valve not only has only unlatching, closes two states, also can be by the time length of control electric-controlled ball valve action, define big flow, intermediate flow, three kinds of states of less flow again, amount to five kinds of states, thereby realize the thick control of low-cost flow size, finally reach the order of the rising or the reduction of temperature.The historical data or the current state data that need to understand all can be printed by mini-printer.For the point more than long lines of controlling, the present invention also is provided with drive circuit, as shown in Figure 2 except adopting a line interface technology and device.This drive circuit resistance R 2 and capacitor C 1 series connection back are in parallel with resistance R 3, the colelctor electrode of transistor T 1 is connected to the intermediate connection point of resistance R 2 and capacitor C 1, the base stage of transistor T 1 and T2 couples together by resistance R 5 and resistance R 4 respectively, resistance R 3 one terminations+5V, a terminated signal lines.Wherein transistor T 2, resistance R 4, resistance R 3 are the basic driver circuit, and transistor T 1, resistance R 2, capacitor C 1 are capacitor compensating circuit.By the capacitance compensation measure, can shorten the charging interval of electric capacity on the transmission line, can make the reliable transmission range of a line reach 800 meters, be 3-4 times of general transmission range.The field by using digital data transmission, anti-interference, effective, save wire rod.The present invention also is provided with telephony interface, and the user can control the opening and closing of heating installation by telephone remote, operates conveniently, saves trouble.Also can be provided with temperature alarming, fault diagnosis, fault location simultaneously, prevent the pipe freezeup supervisor.
The present invention holds multiple function in one, can automatically again can be manual, and reliable effect, cost is low, and is easy to use, is convenient to operation, is suitable for heating such as dwelling house and office building and uses.
