Abstract
The invention discloses a water-saving type metering device. The water-saving type metering device comprises an MCU (Micro-programmed Control Unit), an A/D (Analogue/Digital) converter, a signal processor and a heating radiator, wherein the MCU is connected with the A/D converter and the signal processor in sequence; the heating radiator is further connected with a water inlet pipe, a water returning pipe and an alarm at the same time; a solenoid valve is further connected between the water inlet pipe and the heating radiator; a flow meter A is connected between the water inlet pipe and the A/D converter; a flow meter B is connected between the water returning pipe and the A/D converter; a temperature sensor A is connected between the water inlet pipe and the signal processor; a temperature sensor B is connected between the water returning pipe and the signal processor; the MCU is further connected with an LCD (Liquid Crystal Display); and a filter is further connected between the water inlet pipe and the solenoid valve. With the adoption of the principle, the consumption condition of heat can be accurately metered, conditions that a user illegally uses hot water, water is lost suddenly and the like can be controlled, and an abnormal condition of the heating radiator can also be found in real time, so that resource wastes are avoided at maximum and a metering heat meter can stably work for a long period.
Description
Technical field
The present invention relates to heating equipment, be specifically related to water-saving metering device.
Background technology
District heating system is generally made up of 3 parts, i.e. thermal source, heat supply network and heat user.Thermal source, also known as the production of heating power, is primarily referred to as the boiler room or the steam power plant that produce and prepare certain parameter (temperature, pressure) heating agent.Heat supply network is the outdoor heat supplying pipeline system of conveying heating agent, is the tie that is connected with heat user of thermal source, plays a part to carry and distribute thermal source.Heat user refers to and directly uses or consume the indoor heating of heat energy, air conditioner, hot water supply and production technology hot systems etc..Urban heat supplying is basis instrument, and the heating problem that resident normally passes the winter concerns the lives of the people.Nowadays area of heat-supply service charge is pressed, it is impossible to accurately draw the consumption degree of heat, can only obtain big probable value, be unfavorable for energy-conservation, easily cause the waste of resource；Simultaneously conventional metering hotlist cannot use the situation such as hot water and dehydration to be suddenly controlled to user is violating the regulations, additionally also cannot find in time when radiator occurs abnormal, causes the waste of resource.And calorimeter and adjustment equipment are installed now, and implement to have become as, by the work of table meterage, the focus that central heating industry is paid close attention to.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, water-saving metering device is provided, this metering hotlist can the Expenditure Levels of accurate measurement heat, the situation such as hot water and dehydration suddenly is used to be controlled to user is violating the regulations, the abnormal conditions of radiator can also be found in time, maximized avoid the wasting of resources, it is ensured that the long-term stable operation of metering hotlist.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: water-saving metering device, including MCU controller, A/D converter, signal processor and radiator, described MCU controller is sequentially connected with A/D converter and signal processor, radiator is also simultaneously connected with water inlet pipe, return pipe and alarm, electromagnetic valve it is also connected with between water inlet pipe and radiator, connection traffic meter A between water inlet pipe and A/D converter, connection traffic meter B between return pipe and A/D converter, temperature sensor A is connected between water inlet pipe and signal processor, temperature sensor B is connected between return pipe and signal processor, MCU controller is also connected with LCD display, filter it is also connected with between water inlet pipe and electromagnetic valve.This metering hotlist can measure at a point family, mounting temperature sensor and effusion meter while of on water inlet pipe and return pipe also, temperature difference and flow information is passed in and out for monitor in real time hot water, and be converted to, by signal processor and A/D converter, the signal that MCU controller is able to receive that, the heating time that clock unit on recycling MCU controller is collected simultaneously, the caloric value that heating equipment distributes can be calculated, and shown by LCD display, only need to formulate expenses standard below, be charged by caloric value.Compared with adopting area of heat-supply service charge, this kind of charge method is more accurate, better can realize energy-conservation purpose by paying price in use, it is to avoid cause the waste of resource in the past.And hot water flow can be played control action by the setting of electromagnetic valve, and at user's supplying hot water that uses violating the regulations, or the unexpected dehydration caused by other reasons is controlled, and suppresses the generation of wasting phenomenon further.And the alarm connected on radiator, then it is the working condition for monitoring radiator, once occurring extremely sending chimes of doom in time, it is to avoid owing to the reason of radiator causes the damage of other parts.The filter arranged between water inlet pipe and electromagnetic valve can filter out the impurity in water, it is to avoid impurity blocking water pipe, affects the normal operation in later stage.
Described MCU controller is also connected with EEPROM.
The model of described MCU controller is MC9S12G128MLL.The controller function of this kind of model is stable, and cost performance is high.
The model of described signal processor is TDA7402.
Described electromagnetic valve is rustless steel electromagnetic valve.Durable in use, it is especially suitable for the local use being arranged on Long Term Contact water.
Compared with prior art, the invention has the beneficial effects as follows:
1, this programme by measure flow through the hot water volume of heating equipment, inflow temperature, return water temperature measure heat consumption, realize heat accurate measurement, monitor the flow of water inlet pipe and outlet pipe also by effusion meter simultaneously, find that flow injustice MCU controller then can make corresponding prompting, make adjustment in time, it is ensured that its stable normal operation.
2, hot water flow can be played control action by the setting of electromagnetic valve, and at user's use violating the regulations supplying hot water, or the unexpected dehydration caused by other reasons is controlled, and suppresses the generation of wasting phenomenon further.
3, the alarm connected on radiator, then be the working condition for monitoring radiator, once occurring extremely sending chimes of doom in time, it is to avoid owing to the reason of radiator causes the damage of other parts.
