The main controller and branch controller are coupled with optoelectronic isolators. Each branch controller can control 16 emergency lamps and each lamp has one optical sensor with one end connected to control terminal of branch controller.
Description
The present invention is the equipment that a kind of situation that is used for each fire emergency lamp in the building detects automatically, belongs to the fire-fighting electronic apparatus technology.
Fire emergency lamp is widely used in each main thoroughfare mouth of skyscraper or other heavy construction and needs the place of illumination.For these emergency lights can normally be used in mains failure, just must often carry out the situation inspection to the emergency light of being installed, and carry out this work at present all by manually checking one by one, not only take a lot of work, time-consuming, and it is very inconvenient, especially work as emergency light and be installed in the local time that people are difficult for touching, just check inconvenience more.In addition, owing to, be easy to take place the problem of omission with manually checking one by one, if the emergency light of omission is out of joint, when needs used, the emergency light that is installed in herein just can not be brought into play its effect, even brings harm for fire-fighting work and people's life security.
Purpose of the present invention just provides a kind of controller for automatic detecting status of emergency lamp that can detect and control each emergency light automatically.
Controller for automatic detecting status of emergency lamp of the present invention mainly is made up of three parts, i.e. primary controller (1), iversion controller (2), transfer bus (3).Primary controller (1) is connected with the transfer bus (3) that iversion controller (2) is made up of four lines, and this four transmission lines is+the 24V power supply ground wire, signal reception line B, signal transmission line A, primary controller (1).Only need one, iversion controller (2) can have a plurality of according to the occasion of controlling, but all adopts photoisolator to be coupled between primary controller and the iversion controller.Signal output part in the primary controller (1) is that " OUT " end of scrambler U4 joins by the base stage of a phase inverter U7B and transistor T 1, it is that line A is connected that the collector of transistor T 1 sends line with signal in the control bus (3), the signal input part of iversion controller (2) connects the collector that photoelectricity is isolated transistor part among the SI01, and the negative pole of light emitting diode meets the line A in the transfer bus (3) among the photoisolator SI01.Signal output part in the iversion controller (2) connects the base stage of transistor T 2, its collector is connected with the negative pole of light emitting diode among the photoisolator IS02, the emitter of transistor part is connected on signal in the transfer bus (3) to receive line is on the line B among the photoisolator IS02, the signal input part of primary controller (1) is pin " 3 " end that " IN " of demoder U5 terminates at U22A, and transistorized collector is that pin " 6 " terminates on the line B of transfer bus (3) among its pin " 1 " end and the photoisolator U2B.Its course of work is: send a direct impulse signal by primary controller (1), its rising edge makes transistor T 1 conducting, cause the photoisolator IS01 luminotron on the iversion controller (2) to be lighted, triode in the photoisolator is led time, and the input end of iversion controller this moment (2) is that transistorized collector produces a signal of jumping the edge down among the photoisolator IS01.When the following jumping of the direct impulse signal that sends at primary controller (1) along the time, transistor T 1 ends, luminotron in the photoisolator on the iversion controller extinguishes, triode ends, its collector produces one and goes up the jumping edge, so the direct impulse signal on the primary controller (1) is delivered on the iversion controller (2) with anti-phase form.Equally, when iversion controller (2) sends a direct impulse signal, also can be transferred on the receiving end of primary controller (1) with the inversion signal form.So just, finished by primary controller (1) and sent control signal, received by iversion controller (2), and the feedback signal of sending by iversion controller (2), also be transferred to overall process in the primary controller by transfer bus (3) by transfer bus (3).
Coding on the primary controller (2) (START) is start end by 14 ends of U4, U4 just starts work when low level occurring, 17 ends (OUT) output set of pulses signal wherein contains 1-8 end (A0-A7) and puts fixed address information and 10-13 end (D0-D3) control command information.This group pulse signal by four buses be transported on the iversion controller address information and control command information by single-chip microcomputer 8031 programmings by two latch U8, U9(74LS573) supply with.The address code of address information is corresponding with the different address code that each iversion controller has alone, so that carry out addressing, that is: the iversion controller that the address code of having only its address and primary controller to send is identical just has response, and receives the primary controller command information of sending simultaneously.Do not have response with the different iversion controller of address code that primary controller sends, can not receive the control command information of primary controller yet.
Demoder U3F on the iversion controller (2) has decided a fixing address code by eight bit switch S1 to itself putting, and each iversion controller of this address code is to have nothing in common with each other.On 14 ends (IN), transmit the set of pulses signal that primary controller sends, when the address code that wherein contains and fixing address code itself are identical, 17 ends (V.T) will the high jump level, after U4A is anti-phase, make the U8F(YYH26 on the iversion controller) startup work, identical with the YYH26 on the primary controller, it also can send set of pulses signal at 17 ends (OUT), wherein contain intrinsic address code (1-8 end) and response message (10-13 end) itself, same by four bus transfer, turn back to primary controller, and by the U5(YYH27 in the primary controller (2)) 14 ends (IN) receive, YYH27 role on the primary controller and the YYH27 on the iversion controller roughly the same, so primary controller has just received the answer signal that iversion controller is beamed back.
Each iversion controller (2) can be controlled 16 emergency lights, 16 control line L1~L16 are promptly arranged, (D0~D3), therefore the condition information of 16 lamp positions will send back to primary controller on iversion controller, must just can send through 4 times because YYH26 on the iversion controller and YYH27 have only 4 information bits.When emergency light is lighted, low level occurring on the corresponding LX line, is high level when extinguishing, L1~L8 is controlled by U7F in 16 control lines, and L9~L16 is controlled by U11F, and the output of U7F and U11F is divided into two groups respectively on U6F and U10F, every group of 4 lines, which group output is by U6F and U10F control.
The invention has the advantages that: this automatic test controller can be regularly or at any time the emergency light of The whole control scope is carried out the situation test, and the scene shows test results, need not manually the emergency light that is in various places to be checked one by one, saved a large amount of time, alleviated labour intensity, find that indivedual emergency lights go wrong, in time repair, guarantee the serviceability rate of emergency light.In addition, in the process that detects, whole lamps position of can certain iversion controller of control detection being controlled by primary controller, also can be to detect the lamp position that whole iversion controller is controlled, so just can directly detect the situation that certain iversion controller is controlled each lamp position as required, to indivedual easily places of generation problem, carry out the detection of repeated multiple times.The present invention be advantageous in that the transfer bus connection of only being made up of four lines between each iversion controller and the primary controller connects, this not only makes the structure of total system greatly simplify, and has brought convenience for construction and use, has more practicality.
