2, the collection site data send through simply dealt image data to main frame;
Host function: 1, handle slave and send up sampled data and send execution command to slave;
2, the animation process of the demonstration of color page and the page;
3, the collection of data and preservation constantly;
4, warning output function.
Main frame adopts the color touch screen, makes things convenient for interactive operation, and the part instruction of its transmission can be kept in the middle of the slave, and sends data constantly without main frame, as long as the data fill order that the slave reading and saving is got off just can be moved efficiently.Have failover control, slave is taken over control by meeting under the situation that main frame damages, and makes machine can continue operation.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is that the hardware of the utility model main frame is formed structural representation;
Fig. 2 is that the hardware of the utility model slave is formed structural representation.
The specific embodiment
Electric precipitation microcomputer-based intelligent color screen touch controller described in the utility model comprises main frame and slave two large divisions, and two parts interconnect by host interface circuit and slave interface circuit.Fig. 1, Fig. 2 have provided the hardware of main frame and slave respectively and have formed structural representation, main frame is formed the host CPU treatment circuit by a host CPU and data storage circuitry, this host CPU treatment circuit periphery is connected with slave interface circuit, host computer communication interface circuit and color touch screen drive circuit respectively, color touch screen drive circuit is connected to the color touch screen, and the handled easily person finishes mutual and monitors; The slave interface circuit is responsible for and the communicating to connect of this intelligent controller slave; The host computer communication interface circuit can carry out uploading of entire controller system data, realizes further integrated and the long-range supervision and the control of system.
Slave comprises the treatment circuit from CPU, should be from the CPU treatment circuit by constituting from CPU, data storage circuitry and hostdown testing circuit, and the hostdown testing circuit can be taken over control from chance under the situation that main frame damages, make machine can continue operation.The part that main frame sends refers to that the present can be kept in the middle of the slave data storage circuitry, and sends data constantly without main frame, as long as the data fill order that the slave reading and saving is got off just can be moved efficiently.
Be connected with the external signal Acquisition Circuit from the same respectively host interface circuit in CPU treatment circuit periphery, thyristor gating circuit, fault detect warning circuit, host interface circuit is responsible for and the communicating to connect of this intelligent controller main frame; The external signal Acquisition Circuit is used for gathering parameters such as voltage, gas density, temperature in the electric field, processing by the master-slave cpu treatment circuit, pass through thyristor gating circuit, thereby the control thyristor operating angle changes the transformer primary voltage and changes depressor secondary voltage size indirectly, makes judgement by transformer from the obtained controller that feeds back signal to of electric cleaner builtin voltage.If overtension discharges in the electric field, controller can reduce by the voltage of control controllable silicon by voltage inside, slowly voltage is being raise afterwards, allows the secondary voltage of electric field inside always work in peak, thereby increases dust removing effects.The fault detect warning circuit can be done the judgement of being out of order by the signal that transformer feedback is returned, and carries out sound and light alarm thereby trigger peripheral circuit.
