Embodiment
Below in conjunction with accompanying drawing, the communication module of a kind of filter stick proving installation of the present invention is described in detail.
The communication module of a kind of filter stick proving installation as shown in Figure 1, this communication module comprises QTM and starts interface module, QTM-232 communication interface modules, MCU module, PLC-485 communication interface modules and power module, and QTM startup interface module, QTM-232 communication interface modules, PLC-485 communication interface modules are all connected with described MCU module with power module.
As shown in Figure 2, described QTM starts interface module and is connected with the keyboard interface part of QTM monitor station inside, by PLC Long-distance Control QTM monitor station, makes monitor station start detection.PL8 connects the start-up performance key button of QTM monitor station inside, and P16 port is MCU delivery outlet, and PLC is to after MCU mono-order, and the P16 port of MCU exports high level, and now, PL8 is dragged down, and start QTM, LED D5 lights, the startup of instruction QTM.FC-14 is the cable connecting seat of 14, is connected with QTM internal wiring.
As shown in Figure 3, described PLC-485 communication interface modules is connected with the RS232 serial ports of QTM monitor station, receives the parameters value of each batch of filter stick that monitor station detects, and sends MCU module to.Max232 is used to do level conversion, and standard rs232 level is very high, reaches the highest 5V of Transistor-Transistor Logic level that positive and negative 15V. is conventional.Interconnective words, must carry out level conversion, because QTM equipment of serial output voltage is up to 12V, is directly connected can burns out chip with single-chip microcomputer.So carry out level conversion with MAX232.MAX232 chip adopts single+5V Power supply, only needs several external capacitor can complete the conversion of the level from TTL to RS232, altogether two-way.Wherein 13 pin (R1IN), 12 pin (R1OUT), 11 pin (T1IN), 14 pin (T1OUT) are the first data channel.8 pin (R2IN), 9 pin (R2OUT), 10 pin (T2IN), 7 pin (T2OUT) are the second data channel.TTL/CMOS data convert from T1IN, T2IN input RS-232 data to deliver to QTM DP9 plug from T1OUT, T2OUT to; The RS-232 data of DP9 plug export from R1OUT, R2OUT after R1IN, R2IN input converts TTL/CMOS data to.
The difference of UART and the QTM serial ports RS232 in single-chip microcomputer is only the difference of level, QTM serial ports adopts 232 level, single-chip microcomputer UART then adopts Transistor-Transistor Logic level, if do not carry out level conversion, single-chip microcomputer just can not directly communicate with QTM serial ports, RS232 is that a kind of of UART just means that the form of communication protocol is the same, as long as level has been unified, just can directly communicate between the two, as a result this chip of MAX232 is applied, MAX232 to the data communicated between the two without any effect, it is only intermediary, and it is just responsible for level between the two to unify, make there is no the communication barrier between the two.
As shown in Figure 4, described MCU module comprises reset circuit, crystal oscillating circuit, two-way serial ports passage (road is RS232 passage, communicates with QTM, and another road is RS485 passage, communicates with PLC), input and output control port.MCU receives and passes the data of coming by RS232 passage, row relax of going forward side by side, and convert the data layout that PLC can identify and process to, afterwards, MCU passes to PLC the data processed by RS485 passage.
As shown in Figure 5, PLC-485 communication interface modules comprises MAX485 interface chip, and MAX485 interface chip is a kind of RS-485 chip of Maxim company.Adopt single power supply+5 V work, rated current is 300 μ A, adopts half duplex communication mode.It completes function Transistor-Transistor Logic level being converted to RS-485 level.When being connected with single-chip microcomputer, wiring is very simple.Only need the reception of a signal control MAX485 and send.Add build-out resistor, the generally resistance of optional 120 Ω between being held by A and B simultaneously.Wherein RXD1, TXD1 port is connected with MCU, and A, B port is connected with PLC internal circuit, realizes the data transmission between MCU and PLC.
As shown in Figure 6, the 24V electricity of coming from PLC is transformed into 5V supplying module various piece by power module, makes them work reliably.
