For strengthening versatility and realizing the concurrent sequential of multi-path, the personal safety testing mechanism (9) of the utility model design comprises the regularly setting of constant, the programming of path, and the contact discharges the setting of sequential.
Operation principle of the present utility model is as follows:
(with the contact adhesive of relay or the mechanical contact of release is example, same down will control being switched on or switched off of contact to the control of control object by single-chip microcomputer/DSP and RAM (1).Be instantiated as electronic type contact such as controllable silicon also can) control level output to decoding and preserve with latch units (2).These control levels are after electrical level match unit (3), and the break-make of delivering to the contact drives and Overvoltage protecting unit (4), become drive current from its 1～n end output, the adhesive of control relay or release.Electrical level match unit (3) guarantees that relay is in release conditions at single-chip microcomputer/DSP and RAM (1) reseting period.
The on off operating mode of each contact becomes 01 data signal by output point fault detection unit (8) and arrives parallel, serial conversion unit (5), delivers to single-chip microcomputer/DSP and RAM (1) with serial input line again.
Adaptability of the present utility model is strong.The number of path, the number of time sequence status in the path, the precedence of the actuating of relay; the timing of each relay; the personal safety protection is set in which state, all can on-the-spotly set or revise, and the energy long preservation is in house dog and EEPROM unit (6).The setting of these parameters both can be by the keyboard of guidance panel, keyboard input in display interface/serial communication interface (7), the serial port (as RS232C, RS485 etc.) that also can pass through in keyboard, the display interface/serial communication interface (7) downloads in the utility model after host computer (or the long-distance user passes through INTERNET) is with data edition, modification.
The utility model has good safeguard protection and error detection function.For the big occasion of working strength, the staff has some operation against ruless unavoidably, and as cutting, pressing mold etc. are if industrial accident can take place untimely abort actions.The utility model is in sequential working, regularly (as every 1ms) detects the personal safety line, in the state of setting, security exception is arranged,, and go among the EEPROM in house dog and EEPROM unit (6) state recording for future reference with regard to abort process in case find (get rid of and disturb the back).House dog is responsible for the monitoring to the program out of control of the power down of power supply and single-chip microcomputer.Abnormity of power supply or interference can cause that SCM program is out of control, and house dog can in time detect unusual and take measures, and effectively prevents accident.
The sequential of mistake or the damage of contact (making permanent logical or permanent the breaking in contact as relay adhesive spring failure) may damage valuable machinery.Relay is one of device that is easy to damage, and the utility model can detect automatically in running and locate which relay misoperation.If misoperation arranged, can abort process, prevent device damage or industrial accident, and the misregistration state is for future reference in the EEPROM.In addition, because the interference at Industry Control scene is strong, the utility model has the peripheral circuit of eliminating positive negative interference high pressure.
For example, commonly used to various bottles in packaging industry, as Coke bottle, mineral water bottle etc., they are by bottle blowing machine, injection machine manufacturing.Present embodiment is that one 2 tunnel bottle blowing machine sequential is carried out control, the time program process be:
In this example, matched moulds is personal safety detection state with sealing, and the infrared detection line of safety device detects the staff activity of producing in the groove.At this moment, if staff is arranged in interior activity, if mechanical action does not stop, industrial accident can appear.And under other state, need the activity (can not cause industrial accident) of hand, detect so need not carry out the personal safety detection line.High pressure blow-gas or low pressure are blown, and the contact of high pressure gas is non-maintenance, and all the other are for keeping.Before high pressure gas began, all high pressure blow-gas must finish, thereby the last end person of high pressure blow-gas 1 and high pressure blow-gas 2 is the precursor of high pressure gas.Before whole process finished, matched moulds must disconnect at last, and other then can disconnect simultaneously.In this example, be provided with 3 path L1, L2 and L3.
The content of path 1 (L1) is followed successively by: 0 (no precursor) → matched moulds: keep, safety detection → seal: keep, safety detection → put bar 1: keep, non-safety detection → low pressure blows 1: do not keep, non-safety detection → high pressure blow-gas 1: do not keep non-safety detection → end mark.
The content of path 2 (L2) is followed successively by: seal (precursor) → put bar 2: keep, non-safety detection → low pressure blows 2: do not keep non-safety detection → high pressure blow-gas 2: do not keep non-safety detection → end mark.
The content of path 3 (L3) is followed successively by: high pressure blow-gas 1 (or high pressure blow-gas 2) (precursor) → high pressure gas: do not keep non-safety detection → soft contact 1 (connectionless empty contact is used to fill the interval that the contact disconnects) → soft contact 2 → end mark.
Other path: end mark (precursor for " end mark " represent this path need not)
The content of contact turn-off sequence table is: soft contact 1 → put bar 1 → put bar 2 → seal → end mark → soft contact 2 → matched moulds → end mark → end mark.
The single-chip microcomputer AT89C52 that this example is used, the 11MhZ clock, the shortest 5ms of timing, precision is in two one thousandths.
Compared with prior art, the utility model has following advantage:
1, can control many sequential circuits (being multi-path) simultaneously, the product of energy processed complex operation, Be specially adapted to improve class and the output of product;
2, highly versatile adapts to wide, simple to operate. The utility model can at any time define at the scene many and lead to The time sequence status on road; Also can increase, delete, change existing path or time sequence status;
3, the utility model has used technology such as electronic filtering, makes circuit simple, and interference resistance is strong, and device is common, and Resistor-Capacitor Unit is few, be easy to integrated, with low cost (for existing PLC 1/10th or following).Integrated back can replace PLC in most of SECO occasions.Almost control section of the present utility model can be integrated into a chips, become new " single-chip microcomputer " series.After integrated, only need add a spot of peripheral cell and just can work;
4, personal security protection and fault detect and positioner are arranged, the reliability height, easy to maintenance; And parameter and running state information record arranged;
5, network interface is arranged, long-range (host computer) communication/networking function is arranged.
