It should be noted that it is active signal that Image Acquisition terminal node, which sends the first upper command signal, saved from control
The second the next command signal that point is sent can be for for the passive of Image Acquisition terminal node the first upper command signal of transmission
Signal, or active transmission feeds back the active signal of specific objective data to main control node under certain circumstances,
The particular condition is generally mechanical disorder situation or pre-set specific condition, e.g., upright lifting excessive height etc..
When the second the next command signal is sent as active signal form, the specific exchange method of signal and step
S3-1 value S3-2 is essentially identical, need to only turn requesting party and feedback side.
In embodiments of the present invention, for main control node, main control node further includes individually to other each nodes
Command signal interaction, comprising: the scheduling of power-on command signal.
The main control node whether be activated according to emergency stop switch dispatch power-on command signal to flat panel detector node,
High pressure generator node, described first are from control node, second from control node, third from control node and Image Acquisition terminal
Any one in node or more than one node, include the following steps:
S4-1, when emergency stop switch is pressed, send power-on command signal to the flat panel detector node and the figure
Picture acquisition terminal node,
When main control nodal test is pressed to emergency stop switch, and needs to boot up command signal scheduling, transmission is opened
Machine command signal accesses quilt to the flat panel detector node and described image acquisition terminal node in the form of scan round
The case where whether emergency stop switch pressed is recovered, is not pressed after emergency stop switch is lifted according to emergency stop switch scheduling is opened
Machine command signal is to each node.S4-2, when emergency stop switch is not pressed, send power-on command signal to the flat panel detector
It is node, high pressure generator node, first whole from control node, third from control node and Image Acquisition from control node, second
End node,
Emergency stop switch does not press two kinds of situations including restoring after not being pressed and being pressed originally, and two kinds of feelings
Power-on command signal dispatching method corresponding to condition is identical.

In embodiments of the present invention, the third judges whether oppressive force is greater than or equal to preset threshold from control node
Step, comprising:
The third obtains the rotation angle of current C-arm by the main control node from control node, is oppressed object
The specification of thickness and press discs；
It obtains the oppressive force measured value of compressing force snesor and goes out reality with object thickness conversion is oppressed according to calibration parameter
Force value is oppressed, practical compressing force value, relational expression are calculated by the corresponding relationship formula of oppressive force measured value and practical compressing force value
It is as follows:
Fn=Kn*X+Bn
Wherein, Fn is practical compressing force value, and X is oppressive force measured value, and Kn is the coefficient obtained by oppressive force calibration, Bn
For the constant obtained by oppressive force calibration, n is the angle state of C-arm.
Wherein, the calibration parameter obtains have according to the specification conversion of the rotation angle and press discs of the current C-arm
Body is the rotation angle threshold of the C-arm to be divided into n angular interval, and obtain at least two press discs specifications；By each angle
Degree section and press discs specification are combined, and obtain assembled state list；It is described group corresponding to obtain the compressing force snesor
The oppressive force measured value of corresponding each assembled state in conjunction state list；The oppressive force measured value is subjected to specified school
Standard obtains the corresponding calibration parameter of each assembled state, and combines to form calibration parameter column with the assembled state list
Table；
In practical applications, C-arm is from control node real-time sampling compression device pressure sensor, using least square method school
Numerical value that is quasi- and calculating oppressive force.Since the angle of C-arm relative level (or column) is different, oppressive force, which suffers oppression, thinks highly of the heart
Offset and rail friction power variation influence and have relatively large deviation.Therefore, oppressive force calibration needs to distinguish different C-arm angles
State is no less than (0 °, 45 °, 90 °, 135 °) the progress least square method oppressive force calibration of 4 angles in n.In practical application mistake
Cheng Zhong carries out geometric corrections to the oppressive force under non-above-mentioned angle.Since the gravity of different size press discs is different, need to carry out
The corresponding oppressive force calibration of two kinds of specifications.
Judge whether the practical compressing force value is greater than or equal to the specified threshold, wherein the specified threshold is
30N。
In embodiments of the present invention, described to obtain the oppressive force measured value for oppressing force snesor and convert according to calibration parameter
The step of practical compressing force value out, comprising:
The oppressive force measured value of compressing force snesor is obtained, and judges whether the oppressive force measured value is legal；
If so, judging whether compression thickness is legal；
If so, obtained from the calibration parameter list respectively angular interval corresponding with the rotation angle of C-arm with
And calibration parameter corresponding with press discs specification, and the practical compressing force value is conversed according to the calibration parameter.
For device embodiment, since it is basically similar to the method embodiment, related so being described relatively simple
