Description
Technical field
The present invention relates to the circuit, particularly a kind of medicine equipment image bed control circuit that control for medicine equipment.
Background technology
At present, conventional image bed control circui generally adopts micro-chip processor, because of the concussion frequency that its need of work is certain, this just cannot avoid electromagnetic compatibility relevant issues, especially takes the occasion of orthopaedics film, require higher, very easily occur interference phenomenon, impact film making effect, serious meeting affects the diagnosis effect of doctor, thus affect the therapy rehabilitation of patient, all can cause puzzlement to doctor and patient.
Summary of the invention
The object of the invention is to overcome above deficiency, providing that a kind of structure is simple, practical function, antijamming capability strong, stable performance, be particularly suitable for Electro Magnetic Compatibility and require higher medicine equipment image bed control circuit.
Object of the present invention is achieved through the following technical solutions: a kind of medicine equipment image bed control circuit, comprise power input, for the treatment of the power supply treating apparatus of power input, described power input and decoding device, relay controller is connected, described relay controller and motor, phase inverter is connected, described decoding device and phase inverter, code device is connected, described code device is connected with operating status display apparatus and press key input device, the relay controller of described motor adopts 5V to power, described press key input device provides input for code device.
The present invention compared with prior art has the following advantages:
A. circuit adopts the control circui without program, without clock signal, there is not frequency interferences;
B. unique diode coding circuit is adopted to realize keyboard-coding function;
C. the driving relay of motor adopts 5V to power, and make driving and load isolation, reliability is higher;
D. have keypad lock, duty shows.
accompanying drawing illustrates:
Fig. 1 is theory diagram of the present invention;
Fig. 2 is electrical schematic diagram of the present invention;
Number in the figure: 1-power input, 2-power supply treating apparatus, 3-decoding device, 4-relay controller, 5-motor, 6-phase inverter, 7-code device, 8-operating status display apparatus, 9-press key input device.
embodiment:
in order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 to Fig. 2 shows a kind of embodiment of a kind of medicine equipment of the present invention image bed control circuit:, comprise power input 1, for the treatment of the power supply treating apparatus 2 of power input 1, described power supply treating apparatus 2 and decoding device 3, relay controller 4 is connected, described relay controller 4 and motor 5, phase inverter 6 is connected, described decoding device 3 and phase inverter 6, code device 7 is connected, described code device 7 is connected with operating status display apparatus 8 and press key input device 9, the relay controller 4 of described motor 5 adopts 5V to power, described press key input device 9 provides input for code device 7.
Specific implementation step: (see Fig. 2)
1, DC24V power supply is through F1 short circuit, overcurrent protection, C5, C6 filtering, after the anti-interference suppression of D4,
Deliver to relay drive part, R1, DS1 are power supply instruction, and D1, U1, C7, C8, D7 are
24V turns 5V circuit, for decoding circuit etc. provides power supply;
2, D12-D23 is key encoding circuit, when certain switch is pressed, and coding that can be corresponding different, S1 is keypad lock switch, presses rear unblock, and now, locking pilot lamp is bright, represent and unlock, otherwise button is in the lock state;
3, DAS1, D2, D3, D5, D6, D8-D11 are duty display circuit, and when there being button to press, DAS1 lamp is bright, show that a body is just in action.
4, U2 is button decoding circuit, and R2-R5 is pull-up resistor, and when pressing without button, A-D end is high level, output terminal is high, otherwise when having button to press, corresponding output terminal is low, after U3 phase inverter, export high level, deliver to U4 relay and drive, thus control motor action.
This circuit coding circuit realizes keyboard-coding function, when there being switch order, carries out decoding by coding chip to it, then delivers to driving circuit through phase inverter and controls motor action, thus control the posture of bed body.
Circuit of the present invention adopts the control circui without program, without clock signal, there is not frequency interferences, adopt unique diode coding circuit to realize keyboard-coding function, the driving relay of motor adopts 5V to power, and makes driving and load isolation, reliability is higher, has keypad lock, and duty shows.
The present invention has that structure is simple, practical function, antijamming capability strong, stable performance, humanization designing advantage, be particularly suitable for Electro Magnetic Compatibility and require that higher medicine equipment image bed uses.
The another statement of applicant, the present invention illustrates implementation method of the present invention and apparatus structure by above-described embodiment, but the present invention is not limited to above-mentioned embodiment, does not namely mean that the present invention must rely on said method and structure could be implemented.Person of ordinary skill in the field should understand, any improvement in the present invention, replaces and the interpolation of step, concrete way choice etc., all drop within protection scope of the present invention and scope of disclosure implementation method equivalence selected by the present invention.The present invention is not limited to above-mentioned embodiment, and all employings and analog structure of the present invention and method thereof realize all modes of the object of the invention, all within protection scope of the present invention.
