Control system characteristics of the present invention are as follows:
1, the layout of switch board
With reference to Fig. 6; open electrical control cabinet; can see the three-phase electric leakage protection switch on a row left side topmost; shown in figure three; this is the electric master switch of The whole control cabinet; switch is upwards pulled out; total system is in holding state, and on the right of the three-phase electric leakage protection switch is emergency stop switch, when special circumstances are arranged; can press this button; the The whole control circuit will be cut off power supply this moment, to guarantee the safety of the person. in position, the upper right corner, the core component of remote control control is arranged; the digital remote control circuit board for receiving plays the function that wireless remote control receiving key signal and pilot relay move.
A middle row is the 220V A.C. contactor, the major loop of three-phase or monophase machine and control loop, all finish by them, leftmost two is the A.C. contactor of No. 1 electronic cucurbit of three-phase alternating current of control, three four or two on left sides, a left side are No. 2 single-phase electric gourds of control (just on the iron tower the electronic cucurbit of three-phase alternating current the right which), five six or two on left sides, a left side are control No. 3 single-phase electric gourds (position is on the right of No. 2 electric blocks on the iron tower), two of rightmosts be No. 4 single-phase electric gourds of control (the other end of iron tower independently which).
A bottom row is aviation socket and the terminal row that uses when manually controlling, the aviation socket by a left side to by being No. 1 three-phase electric block respectively, No. 2 single-phase electric gourds, No. 3 single-phase electric gourds, No. 4 single-phase electric gourds, release 1 and release 2 as long as a corresponding handle inserts just can use during use, the 1-4 electric block adopts the aviation plug of 4 cores, and release adopts the aviation plug of 2 cores.
2. using method
1). open electrical control cabinet; the three-phase electric leakage protection switch is upwards pulled out; the position that emergency stop switch is ejecting; system just is in the standby "on" position like this; take out corresponding remote controller; just can control all electric blocks lifting (illustrate, the position of the corresponding electric block of telepilot, 1 correspondence is the three-phase electric block; 2 correspondences be No. 2 single-phase electric gourds; 3 correspondences be No. 3 single-phase electric gourds, No. 4 single-phase electric gourds of 4 correspondences, the button left side is to rising; the right is to decline; one side one row is standby button), it is special that what must note is to pin two keys (except 1 and 2 can press simultaneously to rising) simultaneously.
2). at No. 2 and No. 3 electric block places, one 2 core aviation plug is arranged, corresponding is in the electrical control cabinet release 1 and release 2, when using release, aviation plug is inserted on the aviation socket of release correspondence, plug manual joystick on the aviation socket of switch board place correspondence, press two buttons in lower handle place simultaneously, the just energising of colluding of release is opened, and decontrols button, and just colluding of release closed.
3) if. under special circumstances, when remote control can not be used, we can be inserted into corresponding 4 core joysticks on the 4 corresponding core aviation sockets, so just can control the lifting of electric block with manual.
4). after using, pull up the three-phase electric leakage protection switch, regulator cubicle door and locking closes.
The lifting of electric block adopts the examination of remote control side to realize, the step mode of release adopts manual mode to realize (helping reliable like this and safety).
3. control principle
The electrical control main circuit can be referring to Fig. 7, electrical control control circuit such as Fig. 8, single-phase electric gourd control principle such as Fig. 9, three-phase electric block control chart such as Figure 10, the equivalent circuit diagram of transmitter handle such as Figure 11, receiver equivalent circuit diagram such as Figure 12 are (among the figure, 17 pin of IC PT2272 are for receiving the effective status indication, 10 13 pin of IC PT2272 are decoded four data pin, 18 pin of IC PT2272 are ternary (VSSVDD sky) coding pin, and what the pin of LM358 (RXD) was exported is decoded square-wave signal).
The superregenrative reception module has seven exits, be respectively 10,11,12,13, GND, 17, VCC, wherein VCC is the 5V feeder ear, GND is an earth terminal, and 17 ends are the effective output terminal of decoding, the 10,11,12, the 13rd, 10～13 pin of decoding chip PT2272 (SC2272) integrated circuit, for the four figures certificate latchs output terminal, can export the high level about 5V when signal is arranged, the about 2mA of drive current is that a button is corresponding one by one with four on the transmitter.
Receiver module adopts the manufacturing of SMD paster technique to produce, and is the superregenrative reception mode, and it includes amplifies shaping and decoding circuit, extremely easy to use.
1. antenna input has frequency selection circuit, and does not rely on the frequency-selecting effect of 1/4 wavelength antennas, can cut short even remove external antenna when command range is nearer
2. receiving circuit self radiation is minimum, adds the shielding action of the netted ground connection Copper Foil in the circuit module back side, can reduce the leakage of self-oscillation and the intrusion of external interference signal.
3. the receiver copper core inductance that adopts high precision band skeleton is adjusted to sealing behind the 315M with frequency, and this compares with the circuit that adopts tunable capacitor to adjust receive frequency, and temperature, humidity stability and anti-mechanical vibration performance all have very big improvement.It is lower that tunable capacitor is adjusted precision, have only the setting range of 3/4 circle, and controllable impedance can be accomplished the multi-turn adjustment.Can't sealing after the tunable capacitor adjustment finishes because no matter conductor or insulator, various media near or invade the capacity of electric capacity is changed, and then influence receive frequency.Be subjected to displacement between stator and the moving plate when being subjected to vibrating without the tunable capacitor of sealing in addition; Expand with heat and contract with cold during temperature variation and can make distance change between stator and moving plate; Humidity changes because of media variations change capacity; Long-term work also can change capacity because of the oxidation of stator and moving plate in wet environment, these all can have a strong impact on the stability of receive frequency, and adopt controllable impedance just can address these problems, because inductance can carry out sealing after adjustment finishes, the insulator mounting medium can not make inductance value change, and owing to adopt paster technique, so even sharp pounding also needn't worry to receive the frequency drift, the about 500KHz of reception bandwidth of receiving circuit, centre frequency is adjusted at 315MHz during product export, trimming inductance on the receiving chip has the adjustable extent of 5MHz frequency approximately, and not change easily during use is in order to avoid influence performance.
What should be understood that is: the foregoing description is just to explanation of the present invention, rather than limitation of the present invention, and any innovation and creation that do not exceed in the connotation scope of the present invention all fall within protection scope of the present invention.
