When 5, adopting solid-state relay can reduce the lifting motor break-make to the interference of other circuit parts.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
As shown in Figure 1, the utility model is a kind of vibration compaction test apparatus controller, and it comprises frequency converter 9 and display device, and frequency converter 9 is used for controlling the vibration frequency of the vibrating motor 10 of vibration compaction test apparatus.Described display device adopts common liquid crystals screen 7, and frequency converter 9 is electrically connected with singlechip control panel 6.Singlechip control panel 6 is as the core control section of system, respectively be used for input parameter and instruction function button 5, be used for the acquisition instrument position signalling near switch 8, be electrically connected as the Switching Power Supply 4 and the above-mentioned liquid crystal display 7 of entire controller power unit.The utility model adopts singlechip control panel 6 and common liquid crystals screen 7 to replace the programmable controller (PLC) and the dedicated display of available technology adopting, has reduced cost of products significantly; The utility model combines with function button 5 by liquid crystal display 7, makes things convenient for parameter regulation, the operational factor of setting directly perceived of liquid crystal display 7 menu modes and display system.
Wherein, the communication between function button 5 and the singlechip control panel 6, all can adopt photoelectric isolating circuit, can improve the antijamming capability of system, assurance system operation safe and reliable near the communication between switch 8 and the singlechip control panel 6.
Adopt the RS485 communication mode between singlechip control panel 6 and the frequency converter 9, communication is reliably convenient.
Switching Power Supply 4 is electrically connected with solid-state relay 2, and the lifting button 1 of vibration compaction test apparatus connects the rotating of solid-state relay 2 control lifting motors 3.When adopting solid-state relay 2 can reduce lifting motor 3 break-makes to the interference of other circuit parts.
The course of work of the present utility model is as follows:
1, after system powers on, by lifting button 1 can control instrument lifting motor 3 rotating, thereby regulate the position of vibrating device.The user arrives singlechip control panel 6 by the control data or the command signal of function button 5 input systems.
2, after the user sent the command signal of control vibrating motor 10, singlechip control panel 6 and frequency converter 9 carried out the RS485 communication, the startup of control vibrating motor 10, stopped and operation such as frequency conversion.
3, according to user's selection, singlechip control panel 6 is according to user's setting logic, through after a while timing or near the actuating signal of switch 8, control of conversion device 9 stops the running of vibrating motor 10.
