Description

The calorimeter of a kind of intelligence consumption reduction economize on electricity

(1), technical field:

The utility model relates to a kind of calorimeter, particularly relates to the calorimeter of a kind of intelligence consumption reduction economize on electricity.

(2), background technology:

Along with the intelligent development of residential housing, adopted water, electricity, gas in succession, the intelligent acquisition system of three table unifications, along with the reform of heating structure, the heating system of the northern area of China gradually adopts the measurement instrument of calorimeter as household based heat metering.Under the national policy guiding and the market demand, calorimeter has arisen at the historic moment.

In order to adapt to market developing trend, the production that a lot of producers have all dropped into calorimeter, and the calorimeter of former most of manufacturer production, a lot of various problems have appearred in practice, compare the failure rate height with the intellectual water meter of widespread use, its main cause is that intellectual water meter is the intermittent work mode because the mode of operation of calorimeter and water meter is different, the sands are running out of general user's water every day, frequency is not high; And in a single day calorimeter enters 24 hours every days of heating period and is all gathering flow signal and temperature and then real-time calculating calorie value, so the power consumption of calorimeter is bigger, and the power supply mode of calorimeter mostly adopts lithium battery, because the electric energy of lithium battery is limited, power consumption is excessive, and the life-span of battery shortens with regard to corresponding.Because battery can't continue as the calorimeter power supply, calorimeter will be in paralyzed state, can't work on.

Water meter, ammeter are using long time on the market, its mode of operation has obtained to a great extent perfect, and calorimeter is just at the early-stage, and the mode of operation of calorimeter is different with the mode of operation of water meter, ammeter, and this just need do further to improve to calorimeter.

Present calorimeter, technology is more backward, especially the collection of flow, most of analog transmission that adopts is given assembling, measures and is used, all make troubles, a little less than the antijamming capability, function singleness is owing to mostly adopt dry cell power supply, the entire circuit power consumption that makes backward in technique increases, and makes serviceable life of battery shorten and shorten the serviceable life of calorimeter.

(3) utility model content

The technical problems to be solved in the utility model is: overcome the defective of prior art, the calorimeter of the energy-conservation of consumption reduction that a kind of power consumption is little, reliability is high is provided.

The technical solution of the utility model:

Intelligence consumption reduction power-saving technique cooperates novel detection technique---and wireless digital is intercepted the sampling apparatus technology of measuring, make that micro computer can be according to the automatic control of the size of discharge functional module wherein, when in the pipeline during no current, the automatic control function module of micro computer is closed, micro computer is in " sleep " state, thereby it is minimum that power consumption is dropped to, and improves the serviceable life of battery.

Micro computer is connected with flow metering module, system battery and other peripheral circuits respectively, and the flow metering module connects base table, system battery connection traffic metering module and other peripheral circuits.

Disposable lithium battery is adopted in the power supply of the inner microelectronic component of calorimeter, it is to want power consumption that micro computer is gathered flow signal by excitation, and what of power consumption are relevant with the frequency that encourages: when the flow of water big, when flow velocity is fast, the frequent degree of micro computer acquired signal is just high, and power consumption is just big; When the flow of water is little, when flow velocity was slow, the frequent degree of micro computer acquired signal was just low, and power consumption is just little; When in the pipeline during no current, micro computer least in power-consuming is in " sleep " state, and power consumption has only several microamperes.Among 1 year, the calorimeter most of the time is idle, be in idle condition, therefore at non-heating period, we can allow calorimeter be in dormant state, the temperature measurement circuit of calorimeter stops thermometric, the LCD display module also stops video data, and the frequency of the flow detection of calorimeter is adjusted into minimum, in case discovery can in time respond when flow is arranged, return to normal operating conditions again, the power consumption of total system is just very low like this.The frequency of our flow detection is according to the flow conversion, and the power consumption that detects the high more system of frequency is big more.Effective like this flow velocity intelligence of utilizing water in the pipeline is the change detection frequency automatically, thereby it is minimum that the loss of battery is dropped to, the serviceable life of having improved battery greatly.

The beneficial effects of the utility model:

1, the microprocessor of calorimeter can reach the purpose that intelligence reduces system power dissipation according to the inner functional module of cutting out of the speed intelligence of current, and is fast when water velocity in the pipeline, when flow is big, and the power consumption of system has tens microamperes; Slow, the flow of water velocity hour in pipeline, the power consumption of system has only 12 microamperes; When in the pipeline during no current, the power consumption of system only has about seven microamperes.Micro computer is in " sleep " state under the situation of no current in pipeline, and this moment, the power consumption of battery was microampere order, and the electric weight of consumption is minimum, has improved the serviceable life of battery greatly.

2, because the calorimeter most of the time all is idle, be in " sleep " state at the non-heating period micro computer, it is minimum that the power consumption of system is dropped to, the serviceable life of raising battery.When moving towards winter by summer, calorimeter begins to enter the heating phase, and at this moment, ducted current increase suddenly, and calorimeter can in time respond, and enters duty, reaches accurate continuous data, can not leak the purpose of adopting data.

3, the utility model is made of the components and parts of low-power consumption, and its supply voltage is between 3V～5.5V, and the supply voltage of entire circuit is low, power consumption is little, its to power supply require low, thereby can prolong serviceable life of supplying cell.

Fig. 1 is the theory structure block diagram of calorimeter intelligence energy-conservation of consumption reduction.

(5), embodiment:

As shown in Figure 1: system battery is powered to system, and the microprocessor of calorimeter is regulated the sample frequency of flow metering module according to the flow velocity of the water that listens to.

Intelligence consumption reduction power-saving technique makes that micro computer can be according to the automatic control of the size of discharge functional module wherein, when in the pipeline during no current, functional module can be closed automatically, micro computer is in " sleep " state, that power consumption is dropped to is minimum thereby reach, improve the serviceable life of battery, reached the purpose of intelligent consumption reduction economize on electricity.

It is to want power consumption that the micro computer of calorimeter is gathered flow signal by excitation, and what of power consumption are relevant with the frequency of excitation, and when the flow of water is big, when flow velocity was fast, the frequent degree of micro computer acquired signal was just high, and power consumption just greatly; When the flow of water is little, when flow velocity was slow, the frequent degree of micro computer acquired signal was just low, and power consumption is just little; So the micro computer of calorimeter can be according to the inner functional module of cutting out of the speed intelligence of current, reach the purpose that intelligence reduces system power dissipation, micro computer is in " sleep " state under the situation of no current in pipeline, this moment, the power consumption of battery was microampere order, the electric weight that consumes is minimum, the serviceable life of having improved battery greatly.Thereby reach the purpose of energy-conservation of consumption reduction.
