Abstract
A remote multi-channel control system using wireless paging system is composed of a wireless paging system and multiple control terminals. The control signal containing address code and operation code is emitted to sky via telephone and wireless paging system and them received by the RF receivers of all control terminals whose EEPROM contains local address code and more operation codes. After amplified, demodulated and compared, only the control terminal whose local address code and operation codes are matched can generate relative action signal to control electromagnetic switch, resulting in its control part to be actuated.
Description
Current, huge numbers of families have been entered at China's kilowatt-hour meter, gas meter, water meter etc., its amount is big, and making becomes a great system engineering to the management of these meters and the aspects such as charge of expense, for a long time, this management is fully by manually carrying out, not only time-consuming, and aspect charge, need administrative staff to make rounds to each other's home, suffer door and discuss, even cause social concern such as the expense of being in arrears with for a long time.IC-card gas meter, ammeter that existing market occurs, can solve this problem on the one hand, but because the problem of IC-card itself is subject to assault, and can occur forging new problems such as personation in the process of selling circulation, the use of this IC-card has been limited in some places.
The objective of the invention is to: provide a kind of radio paging system that utilizes to realize the system that remote multi-path is controlled, it can make the operator pass through radio paging system transmit operation instruction, control terminal is received instruct and move by instruction, thereby realize Long-distance Control.
Because the radio call service is very fast in China's development, except outlying mountain area, its coverage rate is very big, and the scope of remote multi-path control therefore provided by the present invention can be as small as one family, a community, greatly can be to a county, province even the whole nation, its applicability is very strong.
Its technical scheme is: utilize radio paging system to realize the system of remote multi-path control, control signal is transmitted into the space through radio paging system.All control terminals receive signal that paging system sends after processes such as amplification, demodulation, decodings, afterwards it is compared with this machine address code and in-local sign indicating number, have only corresponding to that control terminal of this machine address code and in-local sign indicating number and control signal just can produce the corresponding action signal by the requirement of control signal, make the control assembly action of control terminal at last, thereby realize Long-distance Control.
In the technical program, the operator needs to the address code of paging number of local paging centers's application as system's control terminal, and all control terminal address codes are completely the same in a control system, so not only can save channel resource but also can not produce any influence to the original business of paging centers.
Further specify the present invention below by embodiment:
The course of work block diagram of Fig. 1 system
Fig. 2 program flow diagram
Fig. 3 control terminal signal processing block diagram
Control system of the present invention is divided the two large divisions, as shown in Figure 1, the one, signal transmitting portions, the 2nd, control terminal (promptly being signal reception, signal processing, control section).The signal transmitting portions is made up of telephone set and radio call dispatching centre, this part can be utilized the armamentarium of existing radio paging system fully, not needing increases any equipment again, only needs during use to get final product to paging centers's called number of application (address code).
Control terminal (signal reception, processing, control section) also as shown in Figure 1, this part is received (comprising frequency conversion, amplification, demodulation), decoding, is known sign indicating number, signal processing, compositions such as control assembly by radio frequency.Decoding, knowledge sign indicating number, signal processing, all be again to work under the instruction of the microprocessor in single-chip microcomputer, as shown in Figure 3, coded stack is that an EEPROM (Electrically Erasable Programmable Read Only Memo) (EEPROM) is mainly used in storage this machine address code and in-local sign indicating number among the figure, before use at first as required, corresponding this machine address code and in-local sign indicating number write memory (in the use, can change).When operating control signal (address code and command code) through phone and above-mentioned a series of process to decoder, under the instruction of microprocessor, at first the address code that deposits in the address code that decoder is sent here and the coded stack is compared, if two address codes are inconsistent, just do not allow follow-up signal (command code) enter, system finishing work, control assembly is failure to actuate; If two address codes are consistent, then allow follow-up control signal (command code) enter, and under the indication of microprocessor, allow it compare with the command code in being stored in coded stack, if the control signal (command code) that comes from decoder is with the command code that is deposited in the coded stack when inconsistent then system's power cut-off again, if it is consistent with a certain command code in being stored in coded stack to come from the control signal (command code) of decoder, then under the indication of microprocessor, produce the corresponding action signal, this signal is after amplifying, remove to drive the control corresponding parts, make the control assembly action, finish the control corresponding function, shown in Fig. 2 program flow diagram.
Utilize this system can realize electricity consumption (as shown in Figure 3), with controls such as gas.For example desire in a certain community, to realize using electric control, at first the operational administrative person is to call number of certain paging centers's application, as application number in 127 paging centers is " 1234567 ", address code as all control terminals in this community, this address code is write in the coded stack of all control terminals in this community, to distinguish the control system of other community.Also the Frequency point of the radio frequency receiving unit of all control terminals in this community to be transferred on the tranmitting frequency of paging centers simultaneously, again the in-local sign indicating number (is set by the operational administrative person afterwards, the corresponding group coding of each control terminal can not repeated code) write in the coded stack.For example the sign indicating number of opening of a certain user power utilization is " 0112345 ", closing short in size is " 1112345 ", after setting up, control terminal is installed in the power line place of registering one's residence (being between power line and user's the electrical equipment), by the connecting and disconnecting between control power line of the relay in the control terminal and the consumer electronics.When the operational administrative person dials 127-1234567 on phone, import a control operation sign indicating number (as 1112345) again after hearing response, all control terminals are just received this signal in this community at this moment, but the in-local sign indicating number that only deposits in coded stack is the p of the control terminal ability of " 1112345 " at single-chip microcomputer
01Hold to produce a pulse voltage, after driving amplification, make the time pulse relay action, power cutoff, similarly, if the operator transmits a command code as " 0112345 " again, control terminal is at the p of single-chip microcomputer
02End produces a pulse voltage, after driving amplification, makes the time pulse relay action, energized.About control to usefulness gas, the control of water and the control of the remote multi-path of other many aspects, method is similar.
