Description
Technical field
The utility model relates to a kind of automatic meter number recorder, particularly a kind of embedded intelligence flow harvester that carries out real-time communication.
Technical background
Present dwelling house comprises that with flow meter table tools such as water meter, ammeter, gas meter, heat energy table mostly are mechanical type table tool, does not possess the function of data remote, can only manual metering.Automatic meter reading system appearred from 1992, but kilowatt meter reading-out system is the mode that adopts centralized automatic meter-reading: in the table tool electron impulse generator is installed, the mechanical rotation conversion of signals of mechanical counter is become electric impulse signal, at premises the pulse collection device is installed, in collector, count, and realize the teletransmission of data.Also having gas alarm and valve interlock function in some system, also all is by alarm signal wire and the long distance of valve driving circuit being guided on the acquisition controller, being handled by the acquisition controller of concentrating.
This mode lasts till the main flow mode that remains centralized automatic meter-reading now, and this mode has the open defect of following several aspects: there is not counting assembly in the table, if it is the pulse outlet line goes wrong, that occurrence count is inaccurate; Collector adopts the mode of the UPS power supply of concentrating, in case ups power breaks down, will cause the inaccurate phenomenon of large-area data; When system installed, building was not also debugged fully generally speaking and is finished, so the electric power system less stable, has the situation of long-time power failure sometimes, takes place thereby cause counting inaccurate situation; Because amount is more in the building, the circuit and the interface on the control terminal for data acquisition at each family are one to one, the therefore phenomenon that causes circuit to fasten one person's story upon another person easily, and difficult timely the discovery; Acquisition control device is arrived in the circuit teletransmission of alarm, pass the valve operation circuit back each family again, caused the warning link too much, circuit is long, causes alarm linkage pass valve unreliable; System does not possess pre paid functionality, and intelligentized degree is high not enough, and charge still has difficulties, and does not thoroughly deal with problems; Because the manufacturer of table tool is not the manufacturer of system, the phenomenon that can occur arguing back and forth over trifles when the inaccurate problem of occurrence count.
Because there are above-mentioned problems in present centralized kilowatt meter reading-out system, therefore, has proposed the notion of intelligent flow table, battery, digital electronic unit, control device and table tool integrator are formed the intelligence table, thereby solve the above problems.Electronics acquisition controller in the table can increase pre paid functionality, and realizes liquid crystal display, thereby has both thoroughly solved charging problem, can utilize the centralized automatic meter-reading network advantages to realize other functions again.
But, because this electronics acquisition controller module is by lithium battery power supply, and, need frequently inquire about communication as supervisory system, all the time all in communication, the electric current during communication will reach about 5mA on the system bus.Because system is the system of bus form, also can wake this table up to the operation of other tables, that is to say that this table does not just have the time of dormancy at all, its minimum working current is exactly 5mA.The lithium battery of 1300mAh can only continuous firing 260 hours, and just 10 days more time, such system can not drop into actual motion at all.

Description of drawings
Fig. 1 is the inner function module catenation principle figure of the utility model embedded intelligence flow harvester.
Fig. 2 is the circuit diagram of the utility model embedded intelligence flow harvester.
Embodiment
As shown in Figure 1, flow harvester adopts the circuit of double processing unit structure.First processing unit 11 is connected with alarm 14, metrical pulse generator 15 and valve 16.First processing unit 11 provides electric energy by internal electric source 18, and in the present embodiment, internal electric source 18 adopts lithium battery.Second processing unit 12 is connected with first processing unit 11 by link block 13.Communication interface 17 is connected with second processing unit 12, and external system can be connected with harvester by this communication interface 17, so that this harvester is provided with and controls.
With the normal domestic use gas meter, flow meter is example, and every month consumption generally is no more than 200m
3, produce 100 pulses if whenever flow through 1m3, then just produced 20000 pulses in one month.Wakeup time when first processing unit 11 whenever is subjected to a pulse is approximately 10ms, and all electric currents when waking up are added up less than 5mA, and then every month is because the electric energy that pulse measurement exhausts is 0.27mAh.Total power consumption in 10 years is 33.3mAh.
The situation of water meter similarly.If ammeter adopts the method for getting pulse at the step motor drive end, suppose that every month consumption is 200kWh, every kilowatt hour is sent 100 pulses, and 10 years because the total power consumption of pulse measurement is E1=34mAh.
Certain operation (when making valve closing as having used up owing to prevalue) takes place when harvester is inner, first processing unit 11 reports a state value by second interface 132 to second processing unit 12, second processing unit 12 system bus during by these harvesters of communication interface 17 inquiry just with this state value reporting system, and no longer expend the electric energy of internal electric source 18.The general several months of this situation takes place once, perhaps takes place never., took place once in every month as hypothesis with harsher condition, each wakeup time was less than 3 seconds, and electric current is not more than 200mA (valve 16 driving times and electric current), and each electric energy that consumes is 0.17mAh.The electric energy that exhausts owing to this situation in 10 years is E2=20mAh.
When system operates be provided with by 17 pairs of these harvesters of communication interface, controlled valve 16 etc., earlier data are write in second processing unit 12, second processing unit 12 connects by the 3rd gives first processing unit 11, complete operation with data transfer.This situation seldom takes place, and takes place 10 times in the period of 10, each power consumption 0.17mAh statistics, power consumption E3=1.7mAh altogether.
When second processing unit 12 powered on, when just bus was connected, second processing unit 12 sent to first processing unit 11 and reads the total data order, and first processing unit 11 is given second processing unit 12 with all data transfer, finishes synchronous operation.Only in maintenance, circuit is destroyed this situation, perhaps takes place under the situation about powering on again behind the mains failure.Each wakeup time was less than 3 seconds, and electric current is not more than 5mA, every day once statistics took place with worst situation, and the electric energy that consumed in 10 years is: E4=15.2mAh.
Have only aforesaid operations first processing unit 11 to participate in, under other situations, first processing unit 11 is in dormant state, and quiescent current is 0.5uA only, even under the situation of sensor (tongue tube closure), power consumption also only is 3uA, Zong power consumption in 10 years is E5=262.8mAh.
Five additions, total power consumption E=E1+E2+E3+E4+E5=34+20+1.7+15.2+262.8=333.7mAh.Power consumption is just less than 1/1000 (power consumption of former mode is 438Ah) of original mode like this.For guaranteeing the life-span, the long-life lithium battery of selecting 1500mAh is as internal electric source 18, and harvester can be guaranteed to use 10 years.
As shown in Figure 2, the A of U6, B end is used to connect communication bus, and the GNN of U6, VCC end connects 5V input power supply.The pulse input and the input of reporting to the police respectively insert processing unit U1 by a resistance, and U1 exports control signal to valve by U3.OP1, OP2, OP3 are that the optocoupler type first that is used for first processing unit 11 and 12 signal transmission of second processing unit connects 131, second connection the 132 and the 3rd connection 133.
