In one embodiment, a kind of fault detection and diagnosis method of computer tomography equipment, comprising:

CT control system 30 receives electronic component fault-signal, and sends electronic component to fault detection and diagnosis unit 20 Fault diagnosis request signal；

The fault detection and diagnosis unit 20 is according to the electronic component fault diagnosis request signal to the component control Unit 10 processed or the electronic component carry out fault detection and diagnosis, and send the fault detection to the CT control system 30 And the result of diagnosis.

Fig. 3 is referred to, in one embodiment, CT control system 30 receives electronic component fault-signal, and examines to failure It surveys and diagnosis unit 20 sends electronic component fault diagnosis request signal；The fault detection and diagnosis unit 20 is according to the electricity Subassembly fault diagnosis request signal carries out fault detection and diagnosis to the component control unit 10 or the electronic component, and To the CT control system 30 send the fault detection and diagnosis as a result, step includes:

S111, the CT control system 30 receives hospital bed fault-signal, and examines to sickbed control unit 110 and the failure It surveys and the hospital bed fault detection and diagnosis module 210 of diagnosis unit 20 sends hospital bed fault diagnosis request signal；

S112, it is described that the hospital bed fault detection and diagnosis module 210 judges whether the CT control system 30 receives The response of hospital bed fault diagnosis request signal；

S113, it is described if the CT control system 30 does not receive the response of the hospital bed fault diagnosis request signal 210 diagnostic result of hospital bed fault detection and diagnosis module is that the CT control system 30 is communicated with the sickbed control unit 110 Failure, the hospital bed fault detection and diagnosis module 210 send communication failure signal to the CT control system 30.

In the step S111, the sickbed control unit 110 is mobile for controlling hospital bed.When the CT control system 30 when detecting that hospital bed is not moved by actual instruction, can determine hospital bed failure.At this point, the CT control system 30 receives disease Bed fault-signal, and hospital bed failure is sent to the sickbed control unit 110 and the hospital bed fault detection and diagnosis module 210 Diagnose request signal.

When the CT control system 30 sends the hospital bed fault diagnosis request signal to the sickbed control unit 110 Afterwards, if the CT control system 30 communicates normally with the sickbed control unit 110, the CT control system 30 can be received To the response of the hospital bed fault diagnosis request signal sent from the sickbed control unit 110.If the CT control System 30 processed and 110 communication failure of sickbed control unit, then the CT control system 30 can not receive the hospital bed event The response signal of barrier diagnosis request signal.At this point, the hospital bed fault detection and diagnosis module 210 detects CT control system The response that system 30 does not receive the hospital bed fault diagnosis request signal, then be diagnosed as communication failure, and by communication failure signal To the CT control system 30.

In one embodiment, the fault detection and diagnosis method of the computer tomography equipment further include:

S114, it is described if the CT control system (30) receives the response of the hospital bed fault diagnosis request signal Hospital bed fault detection and diagnosis module 210 judge the sickbed control unit 110 whether failure；

S115, if 110 failure of the sickbed control unit, the hospital bed fault detection and diagnosis module 210 sends disease Bed control unit fault-signal is to the CT control system 30；

S116, if the sickbed control unit 110 does not break down, the hospital bed fault detection and diagnosis module 210 Driving motor fault-signal is sent to the CT control system 30.

In the step S114, when the CT control system 30 communicates normal with the sickbed control unit 110, then Hospital bed fault-signal may be due to caused by the sickbed control unit 110 or driving motor failure at this time.

Wherein, 110 failure of sickbed control unit is broadly divided into output control signal fault and input feedback signal event Barrier.Input feedback signal failure refers to the feedback signal failure for being input to the motor of the sickbed control unit 110.When the hospital bed When control unit 110 receives the signal of Mobile sickbed, control signal can be exported rotate motor.But when the hospital bed When control unit 110 breaks down, when can not export control signal, then it can not start motor, will lead to motor at this time can not be just Often rotation, can not Mobile sickbed.Also, when the sickbed control unit 110 breaks down, when input feedback signal failure, The state that motor can then be reported by mistake, also results in mistake.

For output control signal, the sickbed control unit 110 output when can inform the hospital bed fault detection and The state of the output control signal of diagnostic module 210.Meanwhile the hospital bed fault detection and diagnosis module 210 can real-time online prison Control output control signal.When output controls signal fault, the judgement of hospital bed fault detection and diagnosis module 210 described first is at this time Whether the output control signal condition of output control signal and advance notice is identical.If identical, the sickbed control unit 110 is normal.If it is different, then 110 failure of sickbed control unit.

Specifically, the sickbed control unit 110 can inform the hospital bed fault detection and diagnosis module 210 in output Output control signal is low level or high level.Meanwhile the hospital bed fault detection and diagnosis module 210 can real-time online monitoring Output control signal, if whether the low level or high level of output control signal and advance notice are identical at this time.If identical, Then the sickbed control unit 110 is normal.If it is different, then 110 failure of sickbed control unit.

For input feedback signal, when a failure occurs it, input feedback signal is disconnected, and certainly by input feedback signal access Diagnose loop.The hospital bed fault detection and diagnosis module 210 judges whether input feedback signal link is normal.If normal, then 210 diagnostic result of hospital bed fault detection and diagnosis module is driving motor failure.If abnormal, the hospital bed fault detection And 210 diagnostic result of diagnostic module is 110 failure of sickbed control unit.

Specifically, it is formed by switching switch, input feedback signal interface link and output control signaling interface link Self diagnosis loop.Self diagnosis loop is the pumping signal circuit to input feedback signal.It is diagnosed when to input feedback signal When, input feedback signal corresponds to a diagnosing sequence signal at this time.The hospital bed fault detection and diagnosis module 210 passes through control Input feedback signal link is accessed self diagnosis loop by switching switch, and loops back to output control signaling interface link.At this point, The hospital bed fault detection and diagnosis module 210 obtains input feedback signal corresponding diagnosing sequence letter after self diagnosis loop Number, and the corresponding diagnosing sequence signal of input feedback signal when with without self diagnosis loop compares.When by autodiagnosis It is when corresponding diagnosing sequence signal is identical when corresponding diagnosing sequence signal is with without self diagnosis loop behind abscission ring road, then described Sickbed control unit 110 is normal.If it is different, then 110 failure of sickbed control unit.

Therefore, by the step S111 to the step S113, may be implemented to the CT control system 30 with it is described Sickbed control unit 110 communication whether the detection of failure.By the step S114 to the step S116, may be implemented to institute State sickbed control unit 110 whether failure detection and to driving motor whether the detection of failure.To pass through the step S111 realizes the fault detection to entire hospital bed controlling system to the step S116.Also, extremely by the step S111 The step S116 improves fault location the reason of can specifically navigating to which component malfunction and break down Efficiency, can quickly help user or maintenance personal explicitly to prompt, improve work efficiency.

Meanwhile by the step S111 to the step S116, by the hospital bed fault detection and diagnosis module 210 The detection and diagnosis to entire sick bed system can be realized, it can be independently of the failure of the computer tomography equipment itself Detection system.By the step S111 to the step S116, the CT control system 30 can solve due to data service The problems such as measuring fault misdescription caused by the reasons such as heavy, failure cause is complicated or failing to report.

Fig. 4 is referred to, in one embodiment, CT control system 30 receives electronic component fault-signal, and examines to failure It surveys and diagnosis unit 20 sends electronic component fault diagnosis request signal；The fault detection and diagnosis unit 20 is according to the electricity Subassembly fault diagnosis request signal carries out fault detection and diagnosis to the component control unit 10 or the electronic component, and To the CT control system 30 send the fault detection and diagnosis as a result, step includes:

S211, the CT control system 30 receive high pressure generator fault-signal, and to the fault detection and diagnosis list The high pressure generator fault detection and diagnosis module 220 of member 20 sends high pressure generator fault diagnosis request signal, the high pressure Generator fault detection and diagnosis module 220 obtains high pressure generator wrong data；

S212, the high pressure generator fault detection and diagnosis module 220 judge that the high pressure generator wrong data is No exception；

S213, if the high pressure generator wrong data is abnormal, the high pressure generator fault detection and diagnosis module 220 abandon the high pressure generator wrong data.

In the step S211, when high pressure generator, which reports an error, to break down, the high pressure generator fault detection and Diagnostic module 220 reads the high pressure generator wrong data in the error register of the high pressure generator control unit 120.

In the step S212 and the step S213, the high pressure generator fault detection and diagnosis module 220 is right The high pressure generator wrong data is judged.Wherein, the high pressure generator wrong data includes that current loop is unstable, electric Pressure ring road shakiness, unexpected unwrapping wire, anode rotor fault, power component overtemperature, relay failure, cathode sparking and cathode mistake Pressure etc..Such as: under normal circumstances, current loop shakiness and unexpected unwrapping wire can not occur simultaneously.If current loop is unstable When occurring simultaneously with unexpected unwrapping wire, then it is assumed that abnormal (the i.e. illegal mistake of the high pressure generator wrong data obtained at this time Accidentally data), it is believed that it is invalid, directly abandon.

S214, if the high pressure generator wrong data is normal, the high pressure generator fault detection and diagnosis module 220 pairs of high pressure generator wrong data parse；

S215, the high pressure generator fault detection and diagnosis module 220 are sentenced according to the high pressure generator wrong data Whether the high pressure generator wrong data of breaking is related with high pressure generator control unit 120；

S216, if the high pressure generator wrong data is unrelated with the high pressure generator control unit 120, the height Pressing 220 diagnostic result of generator fault detection and diagnosis module is the high pressure generator wrong data and the high pressure generator Control unit 120 is unrelated, and is sent to the CT control system 30.

The high pressure generator control unit 120 is for controlling high pressure generator.High pressure generator is used to provide to X-ray tube High voltage direct current source.

In the step S214 and the step S215, current loop shakiness represents output electric current and exceeds prescribed limit. It is specific to solve when the high pressure generator fault detection and diagnosis module 220 parses the high pressure generator wrong data Analysis is as follows, and voltage loop shakiness represents output voltage beyond prescribed limit.It is unexpected that unwrapping wire represent the detection when not opening high pressure There is high voltage output to output.Anode rotor fault represents anode driver failure.Power component overtemperature represents power device Temperature overtemperature.Relay failure represents relay and can not be attracted.Cathode sparking represents cathode and spark phenomenon occurs.Cathode over-voltage generation Table cathode output voltage is greater than prescribed limit.

The high pressure generator wrong data is solved by the high pressure generator fault detection and diagnosis module 220 Analysis, can specifically judge it is which kind of failure.High pressure command signal is opened when the high pressure generator control unit 120 receives When, the high pressure generator control unit 120 can export control signal to high pressure generator.However, working as the high pressure generator When 120 failure of control unit, high pressure generator can not be just opened.At this point, the high pressure generator wrong data then thinks and institute It is related to state high pressure generator control unit 120.The high pressure generator wrong data and the high pressure generator control unit 120 Related situation further includes the input feedback signal failure of the high pressure generator control unit 120, the feedback of high pressure generator Signal fault etc..

S217, if the high pressure generator wrong data is related with the high pressure generator control unit 120, the height Pressure generator fault detection and diagnosis module 220 obtains the interface status information of the high pressure generator control unit 120；

S218, the high pressure generator fault detection and diagnosis module 220 is according to the interface status information, described in judgement Whether interface status information is abnormal；

S219, if the interface status information is abnormal, the high pressure generator fault detection and diagnosis module 220 is diagnosed It as a result is 120 failure of high pressure generator control unit, the high pressure generator fault detection and diagnosis module 220 sends height Press generator control unit fault-signal to the CT control system 30；

S220, if the interface status information is normal, the high pressure generator fault detection and diagnosis module 220 is diagnosed It as a result is high pressure generator failure, the high pressure generator fault detection and diagnosis module 220 sends high pressure generator failure letter Number to the CT control system 30.

The interface status information includes output control signaling interface status information and input feedback signal Interface status letter Breath.Input feedback signal refers to the feedback signal failure for being input to the high pressure generator of the high pressure generator control unit 120.When When the high pressure generator control unit 120 receives signal, control signal control high pressure generator can be exported.But when defeated When control signaling interface breaks down out, when can not export control signal, then it is unable to control high pressure generator.Also, when input When feedback signal interface breaks down, then it can report the state of high pressure generator by mistake, also result in mistake.

Signaling interface status information is controlled for output, the high pressure generator control unit 120 can be informed in output The output of the high pressure generator fault detection and diagnosis module 220 control signaling interface status information.Meanwhile the high pressure occurs Device fault detection and diagnosis module 220 can real-time online monitoring output control signaling interface status information.When output controls signal When interface fault, the judgement of the high pressure generator fault detection and diagnosis module 220 output control at this time signaling interface shape described first Whether the output control signaling interface status information of state information and advance notice is identical.If identical, the high pressure generator Control unit 120 is normal.If it is different, then 120 failure of high pressure generator control unit.

For input feedback signal interface status information, when a failure occurs it, input feedback signal is disconnected, and will input anti- Feedback signal accesses self diagnosis loop.The high pressure generator fault detection and diagnosis module 220 judges input feedback signal link It is whether normal.If normal, then high pressure generator failure.If abnormal, 120 failure of high pressure generator control unit.

Specifically, it is formed by switching switch, input feedback signal interface link and output control signaling interface link Self diagnosis loop.Self diagnosis loop is the pumping signal circuit to input feedback signal.When to input feedback signal Interface status When information is diagnosed, the high pressure generator fault detection and diagnosis module 220 is by control switching switch, by input feedback Signal link accesses self diagnosis loop, and input feedback signal loops back to output control signaling interface link.At this point, the high pressure Raw device fault detection and diagnosis module 220 obtains signal of the input feedback signal after self diagnosis loop, and and without certainly Input feedback signal when diagnosing loop compares.When signal of the input feedback signal after self diagnosis loop and without When input feedback signal when self diagnosis loop is identical, then the high pressure generator control unit 120 is normal.If it is different, then 120 failure of high pressure generator control unit.

Therefore, it by the step S211 to the step S213, may be implemented to the high pressure generator wrong data Whether Yi Chang detection.By the step S214 to the step S216, may be implemented to the high pressure generator error number According to whether detection related with the high pressure generator control unit 120.It, can by the step S217 to the step S220 With realize to the high pressure generator control unit 120 whether failure detection and to high pressure generator whether the detection of failure. To realize the fault detection to entire high pressure generator control system by the step S211 to the step S220. Also, which component malfunction can specifically be navigated to by the step S211 to the step S220 and broken down The reason of, the efficiency of fault location is improved, can quickly help user or maintenance personal explicitly to prompt, improve work Make efficiency.

Meanwhile by the step S211 to the step S220, by the high pressure generator fault detection and diagnosis The detection and diagnosis to entire high pressure generator control system can be realized in module 220, can be independently of the computerized tomography The fault detection system of imaging device itself.It can solve CT control system by the step S211 to the step S220 System 30 due to data business volume is heavy, failure cause is complicated etc. caused by fault misdescription or the problems such as fail to report.

Fig. 5 is referred to, in one embodiment, CT control system 30 receives electronic component fault-signal, and examines to failure It surveys and diagnosis unit 20 sends electronic component fault diagnosis request signal；The fault detection and diagnosis unit 20 is according to the electricity Subassembly fault diagnosis request signal carries out fault detection and diagnosis to the component control unit 10 or the electronic component, and To the CT control system 30 send the fault detection and diagnosis as a result, step includes:

S311, the 30 pick-up probe fault-signal of CT control system, and to detector control unit 131 and it is described therefore Barrier detection and the breakdown detector detection of diagnosis unit 20 and diagnostic module 230 issue transmitting terminal fault diagnosis request signal, institute It states detector control unit 131 and first detector diagnosis letter is sent to detector according to the transmitting terminal fault diagnosis request signal Number；

Whether just S312, the breakdown detector detection and diagnostic module 230 judge the first detector diagnostic signal Really issue；

S313, if the first detector diagnostic signal does not issue correctly, the breakdown detector detection and diagnosis mould 230 diagnostic result of block is the transmitting terminal interface fault of the detector control unit 131, the breakdown detector detection and diagnosis 230 transmitting terminal interface fault signal of module is to the CT control system 30.

The detector control unit 131 described in the step S311 is used to carry out detector control and to detector data It is acquired.

In the step S312 and the step S313, the first detector diagnostic signal sends termination for detecting Mouthful whether failure.

When the CT control system 30 to the detector control unit 131 and breakdown detector detection and diagnoses mould After block 230 issues transmitting terminal fault diagnosis request signal, the detector control unit 131 is according to the transmitting terminal fault diagnosis Request signal sends the first detector diagnostic signal to detector.

Meanwhile the first detector diagnostic signal described in the breakdown detector detection and the meeting real-time monitoring of diagnostic module 230 Whether correctly issue.When breakdown detector detection and diagnostic module 230 monitor the hair of the detector control unit 131 The signal of sending end interface is the first detector diagnostic signal, then is expected command signal, correct at this time to issue, transmitting terminal There is no failures for interface.When breakdown detector detection and diagnostic module 230 monitor the detector control unit 131 The signal of transmission end interface be not the first detector diagnostic signal, it is correct at this time to issue, send end interface occur therefore Barrier.

S314, if the first detector diagnostic signal correctly issues, the CT control system 30 is to the detector Control unit 131 and breakdown detector detection and diagnostic module 230 issue receiving end fault diagnosis request signal, the spy It surveys device control unit 131 and second detector diagnostic signal is sent to detector according to the receiving end fault diagnosis request signal, And the second detector diagnostic signal is looped back to the receiving end of the detector control unit 131；

S315, the breakdown detector detection and diagnostic module 230 judge whether the detector control unit 131 is correct Receive the second detector diagnostic signal；

S316, if the detector control unit 131 is not properly received the second detector diagnostic signal, the spy The receiving end interface fault that 230 diagnostic result of device fault detection and diagnosis module is the detector control unit 131 is surveyed, it is described Breakdown detector detection and 230 transmitting and receiving terminal interface fault signal of diagnostic module are to the CT control system 30.

The second detector diagnostic signal for detect receive end interface whether failure.When the CT control system 30 to The detector control unit 131 and breakdown detector detection and diagnostic module 230 issue the request of receiving end fault diagnosis After signal, the detector control unit 131 sends described the to detector according to the receiving end fault diagnosis request signal Two detector diagnostic signals.

Meanwhile the receiving end that the second detector diagnostic signal loops back to the detector control unit 131 being referred to The second detector diagnostic signal is returned to the receiving end for being connected to the detector control unit 131 by self diagnosis loop, With this come judge the detector control unit 131 receiving end whether failure.

Wherein, pass through switching switch, transmitting terminal interface link (the signal output end chain of the detector control unit 131 Road) and the detector control unit 131 receiving end interface link (signal input part) formed self diagnosis loop.Work as progress When diagnosis, second detector is diagnosed by control switching switch and is believed by the breakdown detector detection and diagnostic module 230 Number (output end signal) accesses self diagnosis loop, and the second detector diagnostic signal (output end signal) passes through self diagnosis loop Loop back to the receiving end of the detector control unit 131.At this point, the breakdown detector detection and diagnostic module 230 monitor The detector control unit 131 receive end interface signal (the second detector diagnostic signal by self diagnosis loop it Signal afterwards) it is whether identical with the second detector diagnostic signal (without the signal before self diagnosis loop).When described It is then expected finger when the signal of the reception end interface of detector control unit 131 is identical with the second detector diagnostic signal Signal is enabled, is properly received at this time, the detector control unit 131 receives end interface, and there is no failures.When the detector When control unit 131 receives the signal of end interface with the second detector diagnostic signal difference, it is not properly received at this time, it is described Detector control unit 131 receives end interface and breaks down.

S317, if the detector control unit 131 is properly received the second detector diagnostic signal, the detection Device control unit 131 sends breakdown detector to detector and diagnoses request signal；

S318, the breakdown detector detection and diagnostic module 230 judge whether the detector control unit 131 receives The response of the fault diagnosis request signal from detector；

S319, if the detector control unit 131 does not receive the response of the fault diagnosis request signal, the spy Survey 230 diagnostic result of device fault detection and diagnosis module is detector link failure, the breakdown detector detection and diagnosis mould Block 230 sends detector link fault signal to the CT control system 30；

S320, if the detector control unit 131 receives the response of the fault diagnosis request signal, the detection The transmission of device control unit 131 breakdown detector data are detected to the breakdown detector and diagnostic module 230；

S321, the breakdown detector detection and diagnostic module 230 parse the breakdown detector data, and parsing is tied Fruit is sent to the CT control system 30.

In the step S319 and the step S320, visited when the detector control unit 131 is sent to detector When surveying device fault diagnosis request signal, if detector link is normal, the detector control unit 131 can be received from spy Survey the response of the fault diagnosis request signal of device.If detector link failure, at this time signal can not normal transmission, then it is described Detector control unit 131 not will receive the response of the fault diagnosis request signal from detector.

In the step S321, detector data is indicated generally according to defined format transmission, such as with " D1, D0 " Implementing result of the detector to the detector control unit 131 order ping.Wherein, 0X01 indicates that ping ok, 0X10 are indicated ping failed.When detector data breaks down, mistake may occur for format, and the information data of transmission is caused to occur Mistake, so that detector acquires data exception.It is detected at this time by the breakdown detector and diagnostic module 230 parses institute Breakdown detector data, location data fault source are stated, and parsing result is sent to the CT control system 30.

Therefore, it by the step S311 to the step S313, may be implemented to the detector control unit 131 The detection of transmitting terminal interface fault.By the step S314 to the step S316, may be implemented to control the detector The detection of the receiving end interface fault of unit 131.By the step S317 to the step S321, may be implemented to the spy Device fault data is surveyed to be detected.To realize to entire detector control by the step S311 to the step S321 The fault detection of system processed.Also, detector control can specifically be navigated to by the step S311 to the step S321 Which component malfunction and the reason of break down in system, improves the efficiency of fault location, can quickly help User or maintenance personal explicitly prompt, and improve work efficiency.

Meanwhile by the step S311 to the step S321, by breakdown detector detection and diagnostic module 230 can be realized the detection and diagnosis to entire detector control system, can be independently of the computer tomography equipment The fault detection system of itself.By the step S311 to the step S321 can solve the CT control system 30 due to Fault misdescription caused by the reasons such as data business volume is heavy, failure cause is complicated or the problems such as fail to report.
