Temperature controls module: Because temperature heats with drop in temperature response is slower, reason controls systematic demand to go up in temperature, do not need to use high speed to change processing, on the design relatively compact. On temperature module design, the chooses switch and AD595 temperature of 12 groups of relay compensates by means of circuit, again by A/D change-over circuit hind can by advocate CPU is read take temperature cost. Temperature control output is interrupt program computation to produce Soft PWM with the software of 10ms, send its to positive and negative implement latch, through SSR of drive of smooth coupling interface circuit can reach control output. The software of control module divides temperature to control 2 shares for temperature of automatic PID tuning and PID, among them automatic PID harmonious law is of Ziegler-Nichols of improved for private use pace rank answers test way (Step Response Method) , PID is worth figure program to be as follows: (one) device of the electric heat that start lets heater heat amain. (2) by advocate when CPU computation heats R of the biggest slope (%/min) . (3) cut off heater when temperature reachs the 80% temperature of set point, the time L that computation gives temperature to drop (Min) . (4) value of parameter of PID of cipher out of parameter plan of the R of according to earning, L. 4.
DI/DO module: Normally digital I/O module sets Lv to make cost be designed quite concise, input interface needs to consider smooth coupling segregation and filter wave circuit to inbreak in order to prevent noise, size of the electricity that output interface needs to consider to bear, voltage and prevent advocate because CPU is become device of watchdog of machine generation misoperation (Watch Dog) . 5.
DSP servo controls module: The motivation of whole control system controls mode of control of DSP servo sport trunk, be in so on the design outside the stability of system of do one's best, consider safe control to reach even safeguard character. This systematic place designs servo motion to control module to share 4 movement rod, every movement rod includes interface of a group of 4 quadrantal coder, the speed that 2 groups of A/D regard servo as the axis and torsional monitoring are used, the speed that 2 groups of D/A regard servo as the axis and torsional control command voltage is used, contact of quadruplet I/O number is sent as servo axis can reach condition monitoring to use. The arteries and veins when the DSP of VPC2000E controller tastes a system to Analog Device gives is the ADSP_2101 of 20MHz, tie-in the CPLD that 2 Lattice place manufactures; Make BUS control authority to control interface and decipher to use only among them, another codes as 4 groups tally, I/O, A/D and D/A control interface, watch Dog circuit is controlled by place of a TTL 74LS123, and SRAM 43256 criterion as DSP and advocate CPU data shares an area to exchange control message. Program of software of servo sport control is beg concise, fast, choose assembly language compose so. And fall in safe apprehension circumstance, even is written have function of software Watch Dog in order to avoid advocate CPU falls when machine circumstance servo of happening of out of control is consequently cruel strong issue. Software of servo sport control is to store be in advocate in the ROM DISK DOC2000 of CPU, switch on the mobile phone at the system in checking servo of to load of software of the by means of when ending to control a standard. 6.
The operation shows screen controls module: The function of this module is included show, clavier inputs output. 3, type of full report of Taichun essence machine shoots a forming machine to control systematic framework VPC2000E to make appliance have the following characteristic: ○ uses as compatible as Pentinum CPU to control system and PC_baseD hardware framework, support in system and control software more, and safeguard newlier easily, and the function is more general industrial controller or PLC are powerful. ○ uses DOC2000 DISKRAM to make a system or shape the data stores, because cut off the power,need not worry about a system or cause data prediction of a person's luck in a given year. ○ has interface of network news report, convenient data collect and administrative system build the operation picture that ○ human nature changes, tie-in and large LCD shows, make operate personnel to be held easily accuse. ○ provides PID lukewarm accuse to control module with automatic and harmonious temperature, temperature control can be in ± 0.
Inside 5 ℃ limits. Motion of ○ DSP servo controls module to design, can match driver of much home servo and servo motor are used, fixed position precision (switch model and shoot glue) can achieve ± 0.
01mm limits. Graph 2 for Taichun essence machine full report type shoots a forming machine to control systematic framework to pursue, among them servo motor and driver are tie-in motor of Japanese SINANO servo and driver. Graph type of 2 full report shoots a machine to control systematic framework to pursue 4, the development of epilogue VPC2000E controller pulled open Taichun essence machine and other again not only homebred the technical gap that shoots a mechanism to build a plant, also break through type of Japanese full report to shoot the technical camp of a machine at the same time, fall in the progressively development of function accusing cutting of the feet and function and quality improvement, cut home to be shot gradually shape the market. Because fire forming machine controller,be industrial sex product, and rather than consumes sexual product, be in so the reliability of the product and practical on must special fulfil, prospective PIM report is set except promote continuously existing and electronic-controlled outside quality, face towards at the same time self-correcting, suit or kind research and development of the intelligence such as divine spirit high-ranking control, expectation is in admirable and electronic-controlled on the foundation, it is better to offer a client of quality plastic shoot a forming machine.
