Another technical matters to be solved by this invention is: a kind of mold protecting method under closed loop control mode is provided.
In order to solve the problems of the technologies described above, the method that the present invention adopts comprises following steps:
A) place sensor at the detected position of mould;
B) signal of pick-up transducers induction and amplification;
C) amplifying signal is coupled in the single-chip microcomputer, and as data-storing;
D) data with storage compare processing with the numerical value of presetting;
E) whether basis reaches predefined requirement generation result relatively;
F) if comparative result is for reaching predefined requirement, then to equipment input processing instruction, the mould closure, if comparative result is not for reaching predefined requirement, repeating step b then) to e).
Wherein the described default numerical value of step d) is variable value.
The present invention has following advantage compared with prior art: this system comprises the logical program in hardware cell and the embedding single-chip microcomputer; after amplifying in the collection of signal on the mould; the signal at the controlled position of mould is passed to single-chip microcomputer; computing feeds back to the result control system of equipment through logical program; thereby the topworks that makes opertaing device moves according to the variation of signal in the mould; realize mould closed-loop control in process of production; solve mould protective effect in process of production, with the minimizing that realizes the various wastings of resources and the solution of existing problem.
In addition, the guard method of mould according to the present invention, whether make equipment can perceive mould normal, thus whether judgment task carries out.Just, handle, become the mode of mould closed-loop control, thereby realize mould protective effect in process of production through the protection system of this invention the mode of conventional mould open loop control.

Embodiment
As shown in Figure 2; the present invention is the signal at the controlled position of mould; logical operation through the mould protecting program feeds back to the control system of equipment to the result, thereby the topworks that makes opertaing device moves according to the variation of signal in the mould, realizes mould closed-loop control in process of production.
As shown in Figure 3, the present invention includes: be installed in mould 2, sensor 3, signal pickup assembly 4 and control device 5 in the equipment 1.
Described sensor 3 is installed in the detected position (step 100) of mould 2, described signal pickup assembly 4 is by signal picker 41, signal amplifier 42, amplifying signal follower 43 is formed, sensor 3 electrically connects with signal picker 41, signal picker 41 electrically connects with signal amplifier 42, signal amplifier 42 electrically connects with amplifying signal follower 43, be transported to signal amplifier 42 after signal process signal picker 41 collections by sensor 3 inductions, after amplification enters amplifying signal follower 43 through amplifier, be transported into control device 5 (step 101).
Described control device 5 is made up of signal input unit 51, single-chip microcomputer 52, signal output device 53 and driver 54.Single-chip microcomputer 52 mainly comprises memory 521 and microprocessor 522, the signal that amplifying signal follower 43 is sent by signal input unit 51 is coupled in the single-chip microcomputer 52, whether entering by Signal Monitor 511 of synchronous signal shows, the signal of coupling is stored in as data in the random memory ram of single-chip microcomputer 52 (step 102), in read-only memory ROM, depositing control program, control program can be according to the structure and the equipment difference of mould, simply program is made an amendment, to adapt to different logic requirements, promptly this control program can be a variable program.Microprocessor 522 in the single-chip microcomputer 52 reads the information among ROM and the RAM, the instruction that executive control program sends, the signal data that control program will before have been gathered is as input variable x, computing is carried out according to predetermined in advance function formula Y=f (x) in the input back, compare processing (step 103) with default numerical value, whether reach predefined requirement with the situation that detects present mould, whether basis reaches predefined requirement generation operation result Y (step 104) after the computing, signal output device 53 becomes operation result Y into control signal and sends instruction to driver 54, and the signal of the having no way of Output Display Unit 531 that has of output signal shows simultaneously.If reach predefined requirement, illustrate that the mould As-Is is good, driver 54 is received the instruction back to equipment 1 input processing instruction, then the mould closure is carried out one program in back (step 105); If do not reach predefined requirement, after then driver 54 is received instruction, send the instruction of bright lamp to signal lamp, go to fix a breakdown to remind the operator in the position of indication fault, acquired signal (step 106) again after fault is got rid of.Described default numerical value can be to immobilize, also can be according to the structure and the equipment difference of concrete real work demand, mould, and sample acquisitions under the mould normal operating conditions, and be stored in the single-chip microcomputer 52, promptly Yu She numerical value is variable value.
The present invention is by after amplifying in the collection of signal on the mould, under predefined function condition, the result is fed back to the control system of equipment through computing, thereby the topworks that makes opertaing device moves according to the variation of signal in the mould, realizes mould closed-loop control in process of production.
The present invention not only can use at the mould of plastic cement industry, and also can use in punching press industry, die casting industry etc.Simultaneously can develop new program according to customer requirements, native system can be realized the automatic control to others under new procedure operation, uses more extensive.
