Description
The invention belongs to the supervisory system technical field of being inquired substation by central station in order, ICL is G08B26/00(IPC the 4th edition).
This system is made up of a central station main control computer, the on-the-spot station group of multichannel and signal transmission apparatus.Wherein on-the-spot station can be a warehouse, as military storehouse, national treasury etc., also can be a buildings such as museum, bank etc.The central station controller is a microcomputer, and it is the core part of total system.It can gather all kinds of switching values at each on-the-spot station, the output signal of analog sensor, also can order various actuating units in each on-the-spot station, as gamma camera, thermo hydrograph regulator, electronic password lock, Electrically operated gate, defence topworks etc., program behavior is in accordance with regulations realized thus to the monitoring at the on-the-spot station of a group and the purpose of control.
The technology relevant with the present invention has: self-actuated controller, supervising device, warning device.ICL is respectively G05B11, G08C25, G08B(IPC the 4th edition).Retrieving the technology close with the present invention in Patent Office of the People's Republic of China document shop is U.S Pat 4361832, approval on November 30 nineteen eighty-two, its patent name is " centralized monitoring system automatically ", and international Patent classificating number is G08B29/00, the H04M11/04(third edition).
The various supervisory systems of prior art (comprising No. 4361832 patents of U.S Pat) exist following significantly not enough:
1. each road signal wire of system can only hold 1 or several, also is 15 on-the-spot station extension sets at the most.For the monitoring capacity that enlarges system must increase the monitoring way, promptly to increase signal wire.For remote monitoring system, increase way, it is a lot of that the signal wire cost is improved, sometimes or even unacceptable.The increasable way of system also has certain limitation in addition, so under monitoring occasion capacious, these systems seem powerless.
2. usually, each on-the-spot station requires the information of detection a lot, but each on-the-spot station extension set input signal channel of these systems is few, in order to finish the information detection task, must arrange station, a plurality of scene extension sets.
3. the central station controller is distributed in the touring working method that detects of each sensor employing at each on-the-spot station.More for a long time, the touring sense cycle of system is long in number of sensors, thereby has reduced the reaction velocity of system to anomalous event.Such as, when number of sensors is 10,000, system is 5 minutes to the reaction time of station, scene anomalous event, then the reaction time is 50 minutes as if 100,000 sensors.Obviously this can not make us accepting.Here each input channel of on-the-spot station extension set is only shared by a detector.
4. existing supervisory system all is custom-designed for a certain purpose mostly, thereby the versatility of system is not strong.
5. existing supervisory system does not have to be equipped with effectively the control circuit of the actuating unit of effect in real time, thereby anti-damage performance is poor.
The objective of the invention is to utilize a kind of new design philosophy, monitoring system is worked in a kind of brand-new mode. Compare with existing system: this system cost is low, and the monitoring capacity is big, and is fast to the anomalous event reaction speed, the highly versatile of system, and system also is equipped with the executing agency of effective real-time effect, has improved the protection capability of system.
The present invention realizes its goal of the invention by the following technical solutions:
The one, central station controller is a microcomputer, and the central station computing machine carries out multifunctional monitoring to the on-the-spot station of a group that is articulated on the bus respectively by multiple bus.What system communication adopted is bus type communication structure and counting frequency division formula communication rule.Therefore can articulate large numbers of on-the-spot stations extension sets (can above 256) on each road bus of drawing from central station and can shorten the system communication contact time, the raising system is to the reaction velocity of station, scene incident, the reduction system cost.
Each on-the-spot station extension set of the 2nd, has a nearly hundreds of signal input channel.So not only can survey more information, and the sensor that can adopt several cheapnesss and have a different operating principle surveys the complementary detection mode of same information, reduced the rate of false alarm and the rate of failing to report of system widely.
The 3rd. the information that each sensor at same on-the-spot station sends at first forms on-the-spot station owner's state through local or door voting circuit.During supervisory system work, the touring detection of central station is also stored all on-the-spot station owner's status signals, then these major state signals are analyzed, when finding that some on-the-spot station owner's state takes place when unusual, then, serve successively to determine the character of anomalous event according to these on-the-spot station service class height.After whole services finish, carry out the next round polling period again.The service class at on-the-spot station is by the software definition of microcomputer.
The 4th. explanation of each on-the-spot station detector's status is by the software definition of microcomputer, this just allows to use various possible detectors at each on-the-spot station of system, each the on-the-spot station character that is system is arbitrarily, can be arm store, national treasury, timber field, museum, hotel etc.
The 5th. each on-the-spot station extension set of system is provided with the defence actuator controller, can control defence topworks in real time effectively.This mechanism is subjected to the dual control of on-the-spot station owner's sensor and main control computer.When station, scene aiding sensors detects anomalous event (steal, destroy) when being about to take place, main control computer is removed three roads insurance to topworks (open circuit, short circuit, power supply open circuit) immediately, makes defence topworks enter armed state.At this moment, in case when master reference detected anomalous event, defence topworks acted on immediately, has played defense function effectively.
Because defence topworks can be equipped in the system for field station, for the sake of security, system is divided into following four duties.
1. safe condition: the system that is in a safe condition, only play supervisory function bit to the station, scene.Generally when the competent person entered on-the-spot station, this station, scene should be in a safe condition.At this moment, the defence topworks at this station, scene is in a safe condition, and can never act on.
2. first-degree alert state: be in the station, scene of first-degree alert state, only have warning function, do not have defense function.
3. the secondary state of alert: the technical program five is described to be exactly the situation that on-the-spot stations are in the secondary state of alert.This is a basic duty, other each duty all thus state derive from.
4. three grades of states of alert: very important on-the-spot station should be in three grades of states of alert.Be characterized in that after the system chambers external signal line is destroyed still with not destruction is preceding the same in its defence topworks, has defense function.Each on-the-spot station studies carefully to compete to be in what state, can be defined by software.
The 6th. the on-the-spot station owner's state of supervisory system is should the station, scene during extension set by the central station computer addressing, is formed by the address of this station, scene extension set.
The 7th. the addressing instruction that computing machine sends not only can addressing, and can monitor whether communication line is unimpeded.If break down or cut off in the circuit somewhere, central station can be indicated place, problem place immediately.
The present invention has compared following remarkable advantage with prior art:
The one, quantity of standing at the scene is big, distance, and detector quantity is many, and it is little to be tied to form this increase rate under the type complicated situation.
The reaction velocity of the 2nd, system is fast.System can hold thousands of on-the-spot station extension sets, and every extension set can hold up to a hundred sensors, and in 2 seconds station, scene anomalous event is reacted.
The 3rd. system's highly versatile.Because the meaning of central station display station signal lamp can arbitrarily be changed, system software also is easy to change, thereby applicable to various occasion.
The 4th. system has very strong defense function, and self has certain survivability.
The 5th. duty, service class, the COS at the explanation of on-the-spot station owner's state, each sensor states, each on-the-spot station define by computer software.
The embodiment of the invention is as follows by description of drawings:
Figure one is a system chart.System adopts a microcomputer 1 as the central station controller, and central station is drawn four road communication buses 3,4,5,6 by interface circuit 2, and each road bus is made up of a pair of twisted-pair feeder or a pair of optical cable; Can articulate 333 on-the-spot station extension sets 11 on each road bus, each on-the-spot station extension set has 100 switching value signal input channels, 10 analog signals input channels, tens switching value signal output channels.
Figure two is block diagrams of on-the-spot station extension set 11.It is made up of signal driving/receiver 12, addressing device 13, data looger 14, spot sensor 15, actuator controller 16, topworks 17 etc.
When system began to patrol and examine beginning, at first computing machine 1 sent the zero clearing synchronizing signal by the on-the-spot station of all on four tunnel buses of interface circuit 2, signal driving/receiver 7,8,9,10 extension set 11.Then, computing machine sends first addressing pulse by four tunnel buses to all station, scene extension set addressing devices 13.At this moment, have only and chosen simultaneously by separately first on-the-spot station extension set on four tunnel buses of hardware agreement in advance.Then, read and store these four on-the-spot station extension sets, data looger 14 from this four tunnel bus simultaneously, the major state signal, then send second addressing pulse, at this moment, four major state signals that read are from separately second on-the-spot station extension set on four tunnel buses.Then send the 3rd, the 4th addressing pulse again ..., up to all on-the-spot station extension set gatings and read the major state signal that has stored them till.Then these major state signals being analyzed, whether have anomalous event take place, if do not have if distinguishing, then enter the next round polling period, otherwise, the station, scene that anomalous event is arranged to be served, SO service order is according to being undertaken by the height of the service class of software definition in advance.
Figure three is theory diagrams of on-the-spot station extension set addressing device 13, is made up of reset circuit 20, counting/frequency divider 19, decoding/latch 18 etc.Its function is that the address from central station is deciphered, if address code that should station, scene extension set then orders the electronic switch between this station, scene extension set and communication bus to be opened, cuts off getting in touch between other on-the-spot station extension set and the bus.Addressable controller is basic engineering with the frequency-dividing counter, when step-by-step counting reaches predetermined value, the gating output signal can be arranged, and under the situation of other value, all do not have gating signal to export, She Ji advantage is to reduce system response time like this, not only improve system operation time, and reduced system cost.
Figure four is on-the-spot station data looger 14 theory diagrams.When the strobe pulse of central station computing machine was in low level, to be high level formed data looger or a voting state by 10 2 inputs or door and 10 2 input rejection gates to clear circuit output terminal R, and this voting state is exactly the major state of this station, scene extension set.Be in or during door voting state,, 100 switching value signal input channel K be described then in system if signal output part does not have signal
0-K
99Middle neither one passage has the signal input.Otherwise, have at least an input channel that the signal input is arranged.In order to distinguish that those passages have the signal input, microcomputer must send the strobe pulse of a regulation to this detecting device, and making clear circuit output terminal R is low level, allows the frequency-dividing counter counting, sends strobe pulse then successively.Input channel of every gating just reads and stores the signal of a signal output part, and the signal that is read is exactly the signal of this input channel.At last all output signals are differentiated, known that promptly that passage has the signal input.
