In the present embodiment, described primary scene PLC31, secondary scene PLC32, the 3rd on-the-spot PLC33, the 4th on-the-spot PLC34 and the 5th on-the-spot PLC35 all select siemens PLC 226CNDC type PLC.
In the present embodiment, described 5th on-the-spot PLC35 also with a run-coal bin coal position jam detection equipment connection.
In the present embodiment, described upper computer 1 is connected with center PLC2 by remote I/O system, and described remote I/O system comprises remote I/O master station module, remote I/O substation module, transmits terminal+I/O relay terminal, transmits I/O terminal, delivery module and link adapter.
In the present embodiment, described primary scene PLC31, secondary scene PLC32, the 3rd on-the-spot PLC33, the 4th on-the-spot PLC34 and the 5th on-the-spot PLC35 are connected with the first travelling apron 41, second travelling apron 42, the 3rd travelling apron 43, the 4th travelling apron 44 and the 5th travelling apron 45 respectively by input/output module.
In the present embodiment, described input/output module comprises DC switch amount load module, exchanges load module, direct current output module, relay signal output module, Analog input mModule, analog output module.
As shown in Figure 2, be 1-4 conveyer PLC schematic circuit diagram.Native system comprises five travelling aprons, and because relay-type PLC is more suitable for field condition, therefore on-the-spot PLC all selects siemens PLC 226CNDC type PLC, and due to its position reason, other interlock circuits of 1-4 conveyer and I/O distribute substantially identical.The Main Function of on-the-spot PLC is the start and stop directly controlling corresponding travelling apron, when breaking down in travelling apron operational process, on-the-spot PLC must send control command in time makes associated components action, with quick effectively handling failure, breakdown signal is sent to center PLC simultaneously, and the control signal of receiving center PLC.
As shown in Figure 3, the reason that on-the-spot PLC5 is different from front 4 on-the-spot PLC is the end that its corresponding travelling apron is positioned at whole system to on-the-spot PLC5 schematic diagram, will consider the blockage problem of run-coal bin during design in addition.Therefore need separately to add a run-coal bin coal position jam detection equipment.
The basic element of character of remote I/O system comprises remote I/O master station module, remote I/O substation module, transmits terminal+I/O relay terminal, transmits I/O terminal, delivery module and link adapter etc.Remote I/O main website and its structure of substation module are as shown in Figure 4.
Transmitting these parts of terminal+I/O relay terminal is a combiner, and the function class transmitting terminal is similar to I/O substation module, I/O master station module can be connected, completes I/O info-communication function; I/O relay function provides relay input and output function, and by transmitting terminal and I/O state sent to CPU or receive the output state instruction that CPU sends, completes the I/O input of terminal, output function.These parts are with 16 for base unit, and each parts take a passage.Its structure as shown in Figure 5.
Transmitting I/O terminal, to transmit I/O terminal substantially identical with structure with the Transport terminal function in above-mentioned parts, as shown in Figure 5, is that it configures I/O parts and differs that to establish a capital be relay array, has different configurations according to the product of different model.Delivery module is exclusively used in and is connected with sensor controller, completes the data exchange between sensor and CPU.
Input/output module is the link between PLC and on-the-spot I/O equipment or other peripheral hardwares.PLC reads in main frame by load module the state of commercial unit or production process or information, and main frame exports to actuating unit result by output module.Load module is used for carrying out filtering, isolation, level conversion etc. to signal, and the logical value of incoming signal is delivered to PLC inside safely and reliably.Output module is used for the logic operation result of user program to output to PLC outside.Output module has the effect of isolation PLC internal circuit and outside power element, also has the effect of power gain.
Be illustrated in figure 6 24V direct current load module.In figure, HD74HC373 is No. 8 latch, and SN74HC139 is two-four decoders, and SN74HC244 is bus driver controller.These devices grouping on time will deliver to CPU for information about.Through the dividing potential drop of 2.5k Ω and resistance 1.3k Ω after the switch S of external 24V direct supply closes, the filtering of 1.3k Ω resistance and 100 μ F electric capacity, the burning voltage that 1.3k Ω resistance and stabilivolt 2CW52 form about 3V supplied the light-emitting diode of isolator again after a light-emitting diode, by crossing switching information that isolator secondary side photistor exports again through the filtering of 150k Ω resistance and 22nF electric capacity, form the standard information that suitable CPU needs, receive the input end of HD74HC373 latch, when and how this information deliver to CPU, by CPU and SN74HC139 decoder and the process of SN74HC244 driving governor.Decoder has two terminals to receive address bus AB0, AB1 bis-(4, No. 6 terminals) of system bus, selects latch thus, outer signal is delivered to the data bus DB of system by 1, No. 11 Terminal control.Obtain the contact with CPU by driving governor, and start decoder work, reach the object of the information of reading in.
Fig. 8 is the schematic diagram of direct current output module.In module, electric wiring is made up of two parts substantially, and left-half is control part; Right half part is power output part.The composition structure of control part and input template similar, but here the flow direction of data be export.Therefore contact information used is different.For power output part, when the signal of energy disperser allows to export, first through PC890 optoisolator, through FZL4141 analog line driver, control power transistor 92V powering load through light-emitting diode 90V.Wherein light-emitting diode 90V shows non-loaded output; 820F is overcurrent protection fusion tube, and stabilivolt IN4055 and IN4005 keeps the constant voltage of power supply and mouth to prevent over voltage to the destruction of output module and peripheral hardware respectively.
Fig. 9 is the schematic diagram of relay output module.Principle of work is as follows: when module disables is defeated, no matter the output of buffer register is " 0 " signal or " 1 " signal, the defeated light-emitting diode of optoisolator all can not conducting, so internal output enable signal can not affect the state of mouth, when module allows to export, if buffer register exports as " 0 " signal, optoisolator input diode can not conducting, optoisolator output transistor is in by state, output transistor 10V is caused also to be in by state, output relay coil does not have electric current to be passed through, so output relay contact disconnects.If buffer register exports as " 1 " signal, the conducting of optoisolator input diode, and by the mouth of photoelectric coupling to optoisolator, make output transistor 10V conducting, thus it is electric to make output relay obtain, the output relay closing of contact, output relay coil obtain electric while, light-emitting diode (indicator lamp) 13V branch road also has electric current to flow through, and 13V luminescence represents relay contact closure.Access 2CW65 stabilivolt is the safety method taked to prevent relay coil from producing over voltage when transistor 10V ends power-off.IN4006 diode prevents external 24V vdc reverse.The pizo-resistance of mouth prevents over voltage between relay contact.
Analog input interface circuit structure as shown in Figure 10.Be input to the analog quantity of PLC, first will carry out pretreatment, in this course, by various for outside physical quantity or multiple analog amount signal, become the 0-5V d. c. voltage signal being suitable for A/D conversion.Then the entrance of multiple way switch is delivered to.The analog quantity that the effect of multiple way switch will be changed exactly, by the control of control circuit, receives on A/D.Because in PLC, A/D only has one, and the analog quantity that need sample may by multiple.So just by the continuous switching of multiple way switch, the analog quantity that will change is received on A/D.But in order to monitor the connection of external sensor and Analog input mModule in the PLC of reality, between multicircuit switch and A/D converter, add judgement identification circuit.It is generally before input sample value carries out A/D conversion, has inside modules to send a constant current to input end, and makes this constant current keep the regular hour; Detect the voltage that causes thus simultaneously and compare with certain threshold voltage, if external sensor or connecting cable are bad continuously, then this voltage exceedes threshold voltage, at this moment just thinking that broken string exists.A/D converter is then translated into this input sample value " 0 ".If do not break instruction, A/D converter is translated into signed binary number this.
Digit speech recognition, this is owing to not being all by signed binary number representation in the process of PLC internal data, and be represent with complement code or binary-coded decimal etc. sometimes, and the digital quantity that A/D converter exports generally is signed binary code, therefore, suitable number should be converted to before it participates in computing or be processed.
The data entering data drive unit can be sent in bus driver by the control overflow of system, then deliver on internal system data bus; Also can be sent in intermediate relay, reading in of waiting for CPU module.
