Description
Technical field
The present invention relates to medical Instrument field, particularly the dynamo-electric road of an a kind of bond switching of telepilot main control system.
Background technology
One bond switching machine of general curative instrument field telepilot main control system, actual is a bond switching machine of Remote software simulation, but whole main frame and telepilot are still in electriferous state, namely single-chip microcomputer and each chip charged.
Whole equipment is just in electriferous state, and the result that may cause is that equipment works in beyond thought situation, and does not reach the function of shutdown, and such work may meet accident.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, the on/off circuit that safety and stability is higher.
For solving the problems of the technologies described above, on/off circuit of the present invention, comprises interconnective host control panel and telepilot control panel; Integrated switch voltage stabilizing chip on described host control panel, integrated main control singlechip and power supply of remote controller on described telepilot control panel; The I/O2 end of wherein said main control singlechip is connected with the Enable Pin of described switching regulator IC; The I/O1 end of described main control singlechip is connected with the base stage of triode Q1, and the collector of described triode Q1 is connected between the I/O2 end of described main control singlechip and the Enable Pin of described switching regulator IC, the grounded emitter of described triode Q1; Button is connected between the I/O2 end of described main control singlechip and the Enable Pin of described switching regulator IC; Described switching regulator IC is connected with described power supply of remote controller; Power supply, described power supply is connected with described switching regulator IC and by the Enable Pin of resistance with described switching regulator IC respectively.Described power supply is direct supply.
On/off circuit of the present invention can the opertaing device break-make of powering completely, realizes that it is simple, safety and stable function.
Accompanying drawing explanation
Fig. 1 is on/off circuit schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, on/off circuit of the present invention is described in further detail.
As shown in Figure 1, on/off circuit of the present invention, comprises host control panel and telepilot control panel.On host control panel, the Enable Pin of switching regulator IC controls switching regulator IC and normally works and quit work, when the Enable Pin pin of switching regulator IC be height at ordinary times, switching regulator IC does not work, when the Enable Pin pin of switching regulator IC is low level, switching regulator IC normally works; The voltage that the output terminal of switching regulator IC exports is that host control panel and telepilot control plate are powered.Wherein switching regulator IC can select LM2575 series or LM2576S serial etc.
When off-mode, button is pressed, and make the Enable Pin pin of the switching regulator IC on host control panel be in low level, switching regulator IC normally works; The Enable Pin pin of switching regulator IC can be made to be in high level and to quit work when button S unclamps, in order to overcome this point, the I/O1 pin of the main control singlechip on telepilot master control borad sends high level before unclamping makes triode Q1 conducting, after such button unclamps, the Enable Pin pin of switching regulator IC is still in low level state, thus can normally work, keep the power supply to main frame and telepilot master control borad, complete power up function.
When open state, button S presses, the I/O2 pin senses of telepilot master control borad main control singlechip is to low level, the I/O1 pin of main control singlechip is made to set low level, triode Q1 is in cut-off state, after button S unclamps, the Enable Pin pin of switching regulator IC is high level, closes integrated regulator chip and quits work, namely close the power supply of integrated regulator chip to main frame and telepilot to disconnect, complete shut-off function.
On/off circuit of the present invention can the opertaing device break-make of powering completely, realizes that it is simple, safety and stable function.
Below the preferred embodiment of the invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
