[detailed description of the invention]
Below in conjunction with accompanying drawing, the invention will be further described, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Each multiline controller in the present invention is made up of input/output signal processing module, driver module and outside relay module three part.
Wherein, input/output signal processing module is is main formation with the microcontroller U1 of a high-speed computation, and the model of microcontroller U1 is PIC16C54, and its function is:
1. the state of couple control button KEY1, KEY2 detects;
2. the voltage signal VX1 that sends here of pair driver module and current signal IX1 carries out digitized processing;
3. send startup and Polarity Control voltage signal to driver module;
4. drive corresponding LED light.
Driver module is main formation with some bipolar transistors, and its function is:
1. accept startup that input/output signal processing module A sends here and Polarity Control voltage signal, externally relay module and external module C send or plus or minus have the driving voltage of enough power after treatment;
2. accept the voltage and current feedback signal that outside relay module is sent here, after suitable pretreatment, give input/output signal processing module carry out digitized processing.
Outside relay module is with two relays for main formation, and its function is:
1. the polarity of the driving voltage sent here according to driver module B is an action in two relays;
2. the AC regeneration voltage that controlled plant sends, be transformed to DC low-voltage signal, give driver module B.
Operation principle of the present invention is:
When original state, when SWO1 is low level, T5 ends, and causes V1 to end; When PST1 is high level, cause T4 and T1 conducting, T1 conducting thus make T7 conducting.At this moment 24v can only transfer to the outside relay module C of acceptance by R17, T7 and T4 at M1+ and M1-line.Because RL1 coil resistance and R17 in outside relay module C form a divider, make the voltage <3v of M1+ line, this voltage can not make RL1 action.
When nonserviceabling, as RL1 does not connect or coil open circuit, then the voltage >4v of M1+ line.Flow to the U1 of input/output signal processing module A through VX1, through digitized processing, namely U1 makes the judgement of relay open circuit, lights the malfunction indicator lamp LED2 of modules A.
As RL1 coil short, then the voltage <1v of M1+ line, through digitized processing, namely U1 makes the judgement of relay short circuit, also can light the malfunction indicator lamp LED2 of modules A.
When starting state, after in input/output signal processing module A, U1 detects that KEY1 presses, U1 lights the startup indicator lamp LED3 of modules A.SWO1 pin becomes high level from low level, and now T5 conducting causes V1 conducting, so 24v exports M1+ line to through the T7 of conducting.M1-line receives the ground wire of 24v power supply through the T4 of conducting.Relay R L1 in so outside relay module C obtains electric and action, and its contact can be used to startup external equipment.
On FB1 and FB2, the feedback information of 220v alternating voltage as its state is provided after an external device start, the photoelectricity of photoelectric coupled device U2 is made to accept transistor turns through step-down current limliting, add by M1-electric current, thus the voltage of M1-line is increased, the U1 of input/output signal processing module A is flowed to through IX1, through digitized processing, namely U1 makes the judgement of outside controlled plant action, lights the action indicator LED1 of modules A.Unlike this, start indicator lamp LED3 and just represent that start button is pressed.
As LED1 lights, though LED3 does not work, expression external equipment starts is not that KEY1 presses initiation;
Represent that external equipment presses startup by KEY1 as LED1 and LED3 lights.
When halted state, after U1 detects that KEY2 presses in input/output signal processing module A, extinguish and start indicator lamp LED3.Meanwhile, PST1 pin becomes low level from high level, causes T1 to end, thus T7 cut-off, T4 ends, and T3 ends thus T2 conducting, T8 conducting; T6 conducting.The SWO1 pin of U1 becomes high level from low level, and now T5 conducting causes V1 conducting, so 24v exports M1-line to through the T8 of conducting.M1+ line receives the ground wire of 24v power supply through the T6 of conducting.Relay R L2 in so outside relay module C obtains electric and action, and its contact can be used to remove the self-locking of the external equipment started and stops.The high level of SWO1 only maintains 0.1 second and has just cancelled.Now external equipment FB1 and FB2 provides 220v alternating voltage also to disappear.IX1 recovers initial value, flows to the U1 of input/output signal processing module A, and through digitized processing, namely U1 makes the judgement that outside controlled plant is failure to actuate, and extinguishes the action indicator LED1 of modules A.

D. halted state: after U1 detects that KEY2 presses in input/output signal processing module A, extinguishes and starts indicator lamp LED3; PST1 pin becomes low level from high level simultaneously, causes T1 to end, thus T7 cut-off, T4 ends, and T3 ends thus T2 conducting, T8 conducting; T6 conducting; The SWO1 pin of U1 becomes high level from low level, and now T5 conducting causes V1 conducting, so 24v exports M1-line to through the T8 of conducting; M1+ line receives the ground wire of 24v power supply through the T6 of conducting; Relay R L2 in so outside relay module C obtains electric and action, and its contact can be used to remove the self-locking of the external equipment started and stops, and the high level of SWO1 only maintains 0; Within 1 second, just cancelled, now external equipment FB1 and FB2 provides 220v alternating voltage and also disappear, IX1 recovers initial value, flow to the U1 of input/output signal processing module A, through digitized processing, namely U1 makes the judgement that outside controlled plant is failure to actuate, and extinguishes the action indicator LED1 of modules A.
7. a kind of method about the multi-thread control device of fire fighting linkage equipment as claimed in claim 6, is characterized in that the method for input/output signal processing module is:
A. the state of control button KEY1, KEY2 is detected,
B. the voltage signal VX1 sent here driver module and current signal IX1 carries out digitized processing,
C. startup and Polarity Control voltage signal is sent to driver module,
D. corresponding LED light is driven.
8. a kind of method about the multi-thread control device of fire fighting linkage equipment as claimed in claim 6, is characterized in that the method for driver module is:
A. accept startup that input/output signal processing module A sends here and Polarity Control voltage signal, externally relay module C sends or plus or minus have the driving voltage of enough power after treatment,
B. accept the voltage and current feedback signal that outside relay module C sends here, after suitable pretreatment, give input/output signal processing module A, carry out digitized processing.
9. a kind of method about the multi-thread control device of fire fighting linkage equipment as claimed in claim 6, is characterized in that the method for relay module is:
The polarity of the driving voltage a. sent here according to driver module B determines an action duty in two relays,
B. AC regeneration voltage transformation controlled plant sent is DC low-voltage signal, gives driver module B.
