Abstract
The present invention relates to the control method of dualistic coding in the warning system, belong to the warning device class.In micro-processor controlled warning system, each alarm is joined a code sender, and each ten of alarm and code senders are one group, module of every assembly and a demoder.After alarm equipment alarm, triggering this pack module sends first address code and makes code sender send control code, the corresponding decoder decode of this yard quilt touches corresponding module again and sends second address code, and these two address codes are synthetic in main frame just can to draw the warning position.This method can make warning system reduce by 90% coding module, and the main frame consumption of control module also can reduce 80%, makes system cost cheap, and promotional value is arranged.
Description
The present invention relates to the control method of dualistic coding in the warning system, belong to the warning device system class.
In the existing security alerting system, alarm all is with the geocoding module, and the mode of installation then adopts bus system (two lines), and address code is to pass to main frame with the serial code form, or passes on main frame through extension set, and warning system is Control System of Microcomputer fully.For a big system, for example, there are 10,000 of alarms in a system, module of each alarm band, and that just needs 10,000 block coding modules.In addition, main frame has certain capacity to the control of address code, if its max cap. is 2000 address codes, controlling 10,000 address codes will 4～5 main frame.Below as can be seen concerning a big system,, can make involving great expense of system with a large amount of modules and main frame.
The objective of the invention is to avoid the above-mentioned weak point of prior art, and a kind of control method of dualistic coding is provided, make the present invention reduce the quantity of module widely.Along with the minimizing of module, the consumption of main frame has also reduced naturally, thereby reaches the purpose that reduces cost.
Principle letter of the present invention is chatted as follows:
Fig. 2 is that the control system of a dualistic coding is the block diagram of backup system BH.This control system is assisted microsystem work.It is that intrasystem each alarm is mixed control device, i.e. a code sender.And whole alarms are one group and organize into groups (can enlarge every group quantity as needs by ten.But require the number of contacts of some structure such as relay and the bar number of control bus etc. to adjust accordingly), only join a module and a demoder for every group.Code of demoder (scale-of-two) and module numbering (decimal system) should meet, and the code (scale-of-two) of code sender that alarm is joined and the numbering (decimal system) of alarm itself should meet.Here the alarm of saying comprises fire-alarm and burglar alarm, but both alerting signals of output are similar.Only be that example describes below with the fire-alarm.See Fig. 2.
There is not under the situation of reporting to the police module by signal line X
1Y
1On electric current depend mainly on terminal resistance R
f, as alarm F
11After the warning, start code sender N simultaneously
11With the FN of topworks
11(as relay) moves, and makes the signal wire X of module
1Y
1With a resistance R
6(as 330 Ω) form path, promptly with terminal resistance R
F1In parallel.Cause X
1Y
1On electric current increase, the testing circuit in the module (as voltage comparator etc.) is measured this variation, sends address code just touch module, module M
1Send address code (M
1), it is a serial code.Meanwhile, code sender also sends a control code (string, parallel sign indicating number, voltage code or hybrid code etc.), passes to each demoder by control bus.But have only the code of demoder and the corresponding demoder of this control code that signal output is just arranged.This signal triggers FE(of topworks in this demoder such as relay etc. again) action, thus cause the module M that this demoder joins
2Also can send address code (M
2), Here it is so-called dualistic coding.Successively twice signaling just formed generated code (M
1M
2), and the sign indicating number that successively sends for twice is all by computer communication bus, passes to main frame (or by extension set pass on main frame) respectively and handles there.
For ease of management, generally big system is all adopted burst partition way, constitute the Multistage Control system.As total system being divided into 100 each front ends of alarm front end H(can be house, a building or a courtyard), the several front ends of each district's administration.Also distribute 100 alarms as each front end,, synthesize by ten modules: (M by top said dualistic coding method
1M
1) (M
1M
2) ... (M
10M
1) (M
10M
2) ... (M
10M
10) just can obtain 100 new sign indicating numbers.Therefore can both code of dispensing to 100 alarms.The marshalling at first representation alarm place of generated code (to join module No. identical with alarm) can be described as row, and second representation alarm can be described as row in * number (identical with the numbering of alarm itself) of this group.
The control mode of dualistic coding is divided the dualistic coding of parallel sign indicating number control, the dualistic coding of hybrid code control, the dualistic coding of serial code control again.
The present invention implements with following method:
The micro-processor controlled warning system of a kind of usefulness (as shown in Figure 1), it is made up of alarm, master control system and supplementary controlled system BH.Master control system comprises host A, extension set B, geocoding module M and connects their computer communication bus C
1D
1And C
2D
2Supplementary controlled system BH is arranged on each alarm front end, and it adopts the method for dualistic coding control to assist master control system work.The block diagram of supplementary controlled system BH is seen Fig. 2.It comprises the FN of topworks of code sender N, demoder E, alarm, the FE of topworks, the control bus AB of demoder, module by signal line X, Y.Each geocoding module M one end and computer communication bus C
2D
2Connect, the other end is drawn signal wire XY, terminal resistance R in parallel on it
f, the FN(of topworks such as relay contact etc.) and the FE(of topworks of demoder starting such as relay contact etc.).Each alarm is all put a code sender N, and alarm and code sender are organized into groups, and each ten is one group, and control bus AB connects with each code sender and each demoder again, sees Fig. 2.A module is being administered a group alarm device and a demoder (can expand 15 to from ten for a group as needs), and the code of demoder conforms to the module numbering, and the code of code sender then conforms to the numbering of alarm.When alarm sends alerting signal, make the FN of topworks action, send first address code thereby touched institute's gang mould piece.Simultaneously, the signaling mechanism of code sender sends control code, and this control code is passed to each demoder by control bus.But the demoder that has only the demoder code to conform to control code just has signal output.This signal starts the FE of topworks action again, and the module that this demoder is connected is triggered, and this module is just sent second address code.Supplementary controlled system is finished dualistic coding by this method, the generated code of dualistic coding is divided successively and twice this two part code to be passed to main frame by computer communication bus, synthesize there, retrieve according to generated code, take out from internal memory then that relevant data data (as the alarm position, its title, numbering etc.) shows and printing etc.

The dualistic coding of embodiment 2. hybrid codes control
Hybrid code control is exactly to utilize two-lines to transmit " leading to " and " breaking " (i.e. " 1 " and " 0 ") signal of four kinds of varying levels.Therefore, from encoding characteristics, it is the combination of voltage code and binary code.Four kinds of varying levels respectively have 01,10 and 11 3 state again, so integrate totally 12 kinds of states.The state of these yards is issued demoder with parallel mode again.Thereby it can be called parallel sign indicating number again.It has the advantage of easy decoding.With the identical place of parallel sign indicating number control, just do not repeat.Here mainly introduce the generation circuit of hybrid code and the production method of hybrid code.Fig. 5 is the hybrid code code sender.Relay J

The hybrid code decoding is that code sender becomes the parallel sign indicating number of four same level to the parallel code conversion of two varying levels by the hybrid code control bus, and gives 16 and select 1 analog switching ic to decode for the decoding device.The module that output signal is touched this demoder again and connected after the decoding that code conforms to is sent second address code, thereby finishes the dualistic coding of hybrid code control.If D

2,3,5,7End, the level that end product is received as can be seen is that 01 yard of 6V is transformed into demoder input end A, B, C, D and has just become 0001 four bit parallel sign indicating numbers, so the hybrid code of 12 kinds of states in the table 1 all can become four bit parallel sign indicating numbers after being transformed into A, B, C, D, transfer principle is with top identical, undoubtedly after the different conditions decoding, can connect corresponding passage and common port, now these characteristics are incorporated into table 2.

13Principle of work identical.This external Fig. 6 has also utilized contact J
2-2Sent to the noble potential of 24V for hybrid code control bus b, this just is equivalent to 11 states in the table 2.Decoding device in the dualistic coding system of hybrid code control is not provided with the decoding output channel of this state, so can not give rise to trouble.
The dualistic coding of embodiment 3. serial code control
If what the code sender among Fig. 2 sent is serial code, demoder also is to decode at serial code, just constituted the dualistic coding technology of serial code control like this.Now adopt the ZH8901 integrated circuit.(its duty not only can be changed to send mode but also can be changed to receive mode) constitutes serial code signaling device and decoding device device.ZH8901 has 12 input ends, and each input end has " 0 " or " 1 " this two states.Dualistic coding only needs 10 states, so adopt four code switchs to encode.All resets of input end of signaling device and decoding device 5～12, i.e. ground connection.When the code switch of signaling device is identical with the code switch set of decoding device, could link up between them.Be that the serial code that the signaling device sends has only corresponding decoding device to decode, when the code sender signaling, the T/R end output low-potential signal of decoding device.The T/R of corresponding demoder automatically resets after the signaling device stops signaling, the output high potential signal.The coupling method that ZH8901 is operated in send mode and is operated in receive mode as shown in Figure 7.Fig. 8 is the serial code code sender, signaling device 17 termination control line TR.18 ends and 15 ends join, and pass through D
