The specific embodiment
Below in conjunction with accompanying drawing, further describe the specific embodiment that the present invention is used for the non-contact anti-collision device of medical X-ray equipment, but be not used for limiting protection scope of the present invention.
Referring to Fig. 1, Fig. 2 and Fig. 3.The non-contact anti-collision device that is used for medical X-ray equipment of the present invention, comprise the outer housing 1 that is installed in crashproof zone, be installed in electric machine control system 5 and host computer 6 that electric capacity in the outer housing 1 is surveyed amplification module 2 and equipment, electric capacity is surveyed on the amplification module 2 and is connected with capacitive sensing device 3.When electric capacity is surveyed amplification module 2 and is installed to crashproof zone, note on the module light emitting diode D1 and adjustable potentiometer end outwardly, and 3 core shielding lines are stretched over outside the crashproof zone interface of connection device system and electric capacity detecting module outwardly.
Wherein capacitive sensing device 3 is the exploring electrode lead, and it is used to respond to the capacitance signal in the crashproof zone, can according to equipment might bump at the volley the part shape come its shape of specific design.See Fig. 1: during use, 1 central authorities have the hole with outer housing, are sleeved on the crashproof zone of the C shape arm end of X-ray equipment, the exploring electrode lead just be looped around the hole around, be used for closely responding to the variation of crashproof area capacitance.Capacitive sensing device 3 can also be selected other the device that can inductance capacitance changes for use.
The effect that electric capacity is surveyed amplification module 2 is that the small capacitance of surveying in the crashproof zone changes, and signal is amplified, and is converted to direct current signal, then this signal is sent to the electric machine control system of equipment, makes motor produce corresponding action.Because signal is very little, must be installed in the electric capacity most proximal end to this module nearby.Electric capacity is surveyed the electric capacity detecting module that amplification module 2 can adopt Shanghai rope energy automated system company limited.
Referring to Fig. 4.Survey electrode cable 3 among the present invention twines a circle along crashproof zone and is welded on the electric capacity input that electric capacity is surveyed amplification module 2, and earth terminal and crashproof regions shield layer that electric capacity is surveyed amplification module 2 link together; The signal of electric capacity detection amplification module 2 reaches the electric machine control system 5 of equipment through photoelectric coupling pipe V1.R1 in the circuit, R2 are used for current limliting, and photodiode D1 is used for show state.
The adjustment of detectivity is crashproof region distance adjustment: according to the size of the electric capacity two electrode capacitance amounts of changing, by adjusting the adjustable potentiometer in the amplification module, the triggering opportunity of the switching value signal of telecommunication can be adjusted, thereby the distance in people or the approaching crashproof zone of object can be adjusted.
Energising debugging: connect the 24V dc source that electric capacity is surveyed amplification module 2, when light emitting diode D1 is bright on the module, represent crashproof effective.Allow foreign bodies such as hands or metal object near crashproof region surface, survey the adjustable resistance of amplification module 2, adjust a proper detection range by adjusting electric capacity.
Referring to Fig. 4 and Fig. 5.The realization of crashproof control: after electric capacity is surveyed amplification module 2 output signals process photoelectric coupling pipe V1, be connected to equipment electric machine control system 5, when electric capacity when changing, output signal is a high level, and the signal that is input to electric machine control system 5 is a high level, and is crashproof invalid; When electric capacity was surveyed amplification module 2 and detected capacitance variations, output signal was 0V, and the signal that is input to electric machine control system is a low level, crashproof effectively, electric machine control system 5 allows the motor stop motion or the counter-rotating of current motion.And notice host computer 6 shows " crashproof effective " information, the warning of sounding on display screen.If the effectively back counter-rotating of crashproof signal, equipment directly break away from crashproof zone automatically; If stop motion can allow equipment break away from crashproof zone by motion in the other direction.In a word, when the close crashproof zone of object, the variation that capacitive sensing device 3 inductance capacitances take place, electric capacity is surveyed amplification module 2 and is detected the changes in capacitance signal, convert the electric machine control system that the signal of telecommunication outputs to equipment to, the electric machine control system of equipment receives the signal of telecommunication, moves.
Existing anticollision device, collision-prevention device be foreign body such as people or other objects and crashproof zone is actual takes the technology control method of protective measure after bumping; And the non-contact anti-collision device that is used for medical X-ray equipment of the present invention just can be taked the technology control method of protective measure when being foreign bodies such as people or other objects near crashproof zone; The latter more has superiority aspect the time lead than the former.
The present invention compares than other existing noncontact avoiding collisions, and is simple and reliable for structure.The hardware of device is formed fairly simple, and volume is little, does not need to add new structure when the location is installed, only need on original outer housing, to change slightly, and quick and easy for installation, during installation structure there is not specific (special) requirements yet.The present invention can carry out crashproof detection from a plurality of directions, the crashproof detection basic skills of other noncontacts has usually: visible light, infrared, ultrasound wave, laser, electromagnetism etc., its physical characteristics: straight line and cone are surveyed and all are not suitable for crashproof to large tracts of land and irregular shaped region, especially are fit to the use of medical X line equipment under the room temperature.No matter common in addition contact anticollision device, collision-prevention device, still other non-contact anti-collision devices usually, cost of the present invention is obviously on the low side.
More than be preferred forms of the present invention, according to content disclosed by the invention, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into the scope of protection of the invention.
