Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
As depicted in figs. 1 and 2; The utility model hydraulic headstock gear phonetic alarm device comprise with hydraulic power unit on the PCL controller 2 that is connected respectively of relay and sensor in the hydraulic headstock gear electrical control cubicles 1; The signal output part of PCL controller 2 is connected to the signal input part of single-chip microcomputer 4 after through photoelectricity coupled circuit 3; The signal output part of single-chip microcomputer 4 is connected to the signal input part of speech chip 5, and the signal output part of speech chip 5 is connected to playback loudspeaker 7 through audio amplifier circuit 6.As shown in Figure 4; The control signal of single-chip microcomputer 4 outputs is sent in the second photoelectricity coupled circuit after impact damper 7407 amplifies; The second photoelectricity coupled circuit adopts the TLP521 photoelectric isolating device; The input end of the second photoelectricity coupled circuit is connected with the input current-limiting resistance, and its output terminal connects the signal input part of speech chip 5.
Too high from the DC12V voltage signal that the relay contact of hydraulic headstock gear electrical control cubicles is next, should not be as the input of single chip computer AT 89C51.So between single-chip microcomputer and relay contact, added a photoelectricity coupled circuit 3, both can protect single-chip microcomputer, can play Signal Spacing again; Improve system reliability; Photoelectricity coupled circuit 3 adopts the TLP521 photoelectric isolating device, and the input end of photoelectricity coupled circuit is connected with input current-limiting resistance R, and is as shown in Figure 3; The input current-limiting resistance makes that led current is limited in 10～20mA in the photoelectricity coupled circuit.Input end leans on the light signal coupling, on electric, has accomplished to isolate fully.Simultaneously, light emitting diode forward impedance value is lower, and the internal resistance of external interference source is generally higher, and according to voltage divider principle, it is very little that interference source can be fed to the input end interference noise, can not produce that ground wire disturbs or other are crosstalked, and has strengthened the circuit antijamming capability.
Single-chip microcomputer is selected AT89C51 for use; AT89C51 is the single-chip microcomputer by the complete compatible MSC-51 of atmel corp's production; 1 its maximum characteristics are that Flash EEPROM and 80C51 kernel are combined; Still adopt general structure and the order set of C51, the erasable program storage of Flash can reduce development cost effectively, and single-chip microcomputer is repeatedly used.It has 4 * 8 I/O mouths, 1 serial communication interface, 5 interrupt sources, ROM (EPROM) 4KB in the ram in slice 128KB, sheet.
Single-chip microcomputer output control signal is sent into the photoelectricity coupled circuit after impact damper 7407 amplifies.Resistance R 2 among Fig. 4 is the second photoelectricity coupled circuit output transistor load, and choosing of its size and performance should guarantee that its output transistor is reliably saturated when the conducting of photoelectricity coupled circuit; And when the photoelectricity coupled circuit ended, triode can be reliably saturated.But, limited its frequency of utilization because photoelectricity coupled circuit response speed makes switching delay time lengthening slowly.
Speech chip is selected the ISD4004 chip for use, and the ISD4004 speech chip is the new product of being released by American I SD company, monolithic recording playback voice time 8-16min, and simple to operate, tonequality is good.Chip includes oscillator, the anti-wave filter that mixes; The many level flash storages of smoothing filter, automatic silencing, note amplifier and high density array.Chip design is based on all operations must be by microprocessor controls, and operational order is sent into through serial communication interface (SPI or Microwire).Chip adopts many level direct modeling amount Storage Techniques; Each sampled value directly is stored in the flicker memory in the sheet; Therefore unusual true nature ground realize voice, music, tone and effect sound again avoided general being installed with of solid recording circuit and compressed quantizing noise and the metallic sound that causes.ISD4004 works in the SPI serial line interface, and according to the SPI agreement of synchronous serial data transmission, all serial data transmission start from the chip selection signal SS negative edge that the single-chip microcomputer primary controller sends to ISD4004.SS must remain low level during the transmission, between two instructions, then remains high level.Data from serial data input end MOSI pin are latched at serial synchronous clock rising edge, and the data of ISD4004 serial data output terminal MISO pin are moved out of at the negative edge of SCLK.Any one recording and playback operation (containing F.F.) of ISD4004 are all undertaken by sectional address, and every section comprises several rows, and every row is equivalent to storage unit, carries out the storage administration of recorder information under the control of the address clock signal RAC that is expert at.The RAC signal period is 200ms, and the high level dutycycle is 3/4.When recording and playback operation arrive the end of internal storage unit address; Can produce an OVF or EOM end mark signal; If run into EOM or OVF, then produce a low level effective I NT look-at-me, this interruption status is eliminated when the next SPI cycle begins.
Speech chip ISD4004 is connected as shown in Figure 2 with single chip computer AT 89C51.The chip selection signal SS pin of ISD4004 is connected with the I/O mouth P1.0 of AT89C51 single-chip microcomputer, produces effective low level signal by programmed instruction.Serial data input MOSI pin is connected with P1.3 with P1.1 respectively with serial data output MISO pin, and the data message of serial transmitting-receiving is latched by sheet internal shift register under the control of programmed instruction, and its synchronizing clock signals SCLK is controlled by single-chip microcomputer P1.2.Row address clock RAC is connected with P3.3 (INTO) with P3.2 (INT1) respectively with interrupt request singal INT.
The suggestion voice that the hydraulic headstock gear phonetic alarm device sends like information such as " oil level is low, asks repairing ", " oil level are high, please overhaul ", is cured to the storage unit of the inner E2PROM of ISD4004 by the address segmentation through specialized equipment.Under programmed control, corresponding speech signal, is sent into the low noise power amplification circuit and is amplified through coupling capacitance C4 shown in Fig. 2 and volume control potentiometer RW by the AUOUT output of ISD4004, promotes the loudspeaker sounding.For making the output voice noise reach minimum, the simulation ground of system and cabling are separately digitally linking to each other near the feeder ear place as far as possible, and are guiding to respectively on the VSSA and VSSD pin of ISD4004 chip, and decoupling capacitance also should be as far as possible near chip.
The utility model is inquired about through the alerting signal that PLC controller 2 is sent in real time, judges accurately whether signal is effective, and reliably searches the pairing voice memory address of signal, and taking-up information is carried out real-time broadcasting.Control program comprises powering on and the power down program of primary control program, signal polling routine, voice broadcast program, data convey program, ISD4004, repeatedly uses time delay subroutine, simple in structure, highly versatile in the program.
