Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, a kind of bus remote control based on long-distance meter-reading system M--bus, it comprises PC terminal management device (employing PC), M--bus concentrator (model can be BCZJ--2), M--bus repeater (model can be BCJZ--3), N heat (cold) scale, and N and identical M--bus bus level modular converter and the valve positioner of hot (cold) scale quantity, the control signal output ends of described PC terminal management device links to each other with the signal input end of M--bus concentrator by the RS232 transmission line, the control signal output ends of M--bus concentrator links to each other with the signal input end of M--bus repeater, each control signal output ends of M--bus repeater links to each other with a plurality of M--bus bus level modular converters respectively, each M--bus bus level modular converter respectively with corresponding heat, the cold epiphase connects, each heat, the output of cold table connects the corresponding valve controller respectively.
PC links to each other with the M--bus interface by the RS232 port, and M--bus concentrator thermotropism, cold table are bus voltage (36V) when sending data " 1 ", and bus voltage is (24 V) when sending data " 0 ".Heat, cold table are confirmed the data that receive by the variation of judging the high low-voltage of bus.
Heat, cold table send by changing the M--bus bus when the M--bus concentrator sends confirmation signal.Bus voltage (36V) the drain bus electric current when heat, cold table send " 1 " that remains unchanged be (<1.5) mA, and the drain bus electric current is (11-20) mA when heat, cold table transmission data " 0 ".The M--bus concentrator is confirmed the data that receive by the variation that detects electric current.
Because calorimeter adopts is that therefore the powered battery of 3.6V need be the Transistor-Transistor Logic level signal of 3.6V with the M--bus conversion of signals.This just needs a M--bus bus level modular converter.As shown in Figure 2, M--bus bus level modular converter can be TSS721A by voltage transitions chip U1(model) and the peripheral circuit formation.
Valve positioner of the present utility model is made of valve and actuator, and as shown in Figure 3, T06 and W04 form current driving circuit.
Valve sends control signal by the I/O pin of MCU of heat (cold) scale, and (P6.6 P6.7) controls the both forward and reverse directions running of DC micromotor, to reach out valve or to close the purpose of valve.Whether MCU also will real-time detection valve turns round and puts in place when driving valve or closing valve, and by P6.4, the P6.5 pin detects low level and thinks to open or close and put in place.
In order to increase the driving force of DC micromotor, except increasing drive current, also will mechanically take the principle of gear change.Gear ratio is 1:1000.Be immersed in the problem the design of easily getting rusty in the water for a long time and take copper to mould accessory structure combining mode in order to prevent to control ball valve, promptly the ball valve that rotates adopts casting in bronze to make, and the department's clothes pad in the valve pocket adopts high temperature resistant hard plastic injection molding to form.Also the time switch valve is once turbid with the rust of eliminating on the ball valve weekly for MCU simultaneously.
During concrete enforcement:
PC terminal management device links to each other with the M--bus concentrator by PC RS232 port, and the M--bus concentrator is opened up structure by the repeater benefit and linked to each other with regional each interior ultrasonic calorimeter.Thereby can realize the LAN of PC Long-distance Control instrument.
When the user need arrive PC terminal management department and handles the subscriber data typing and pay pre-cost of use, PC just passes through M--bus bus remote transmission load value data in ultrasonic calorimeter, and ultrasonic calorimeter determines whether Open valve by the value of judging surplus heat after receiving load value data.Instrument will be sent automatically and close valve signal by the valve positioner valve-off when surplus heat in the customer meter is not enough, and the user need arrive and can continue after administrative authority continues to pay dues to use.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
