Machine sends control instruction, and simulation great Zha and little Zha is controlled；Detector is opened, starts test；It is automatically obtained complete automatic
Test, the manual test of single step and automatic calibration of sensor algorithm are comprised the following steps that：
1. complete automatic test：CCBII brakes are made up of many baroque parts, completely certainly
Dynamic test refers to that all parts are tested according to the following steps respectively：
(1) network parameter test：Asked including electrical testing on LRU (replaceable unit) and running parameter；
(2) state initialization：Host computer is simulated integrated processor module (IPM) and sends system initialization data group bag, inspection
Survey whether LRU completes to initialize and send normal ERT sensing datas and MRT sensing datas to host computer；If so, then after
It is continuous to carry out next step；Otherwise, host computer prompting failure；

Corresponding component test is carried out, for individually being tested certain part, testing procedure is with complete automatic test.
3. automatic calibration of sensor step：During complete automatic testing process and the manual test of single step, all can
Carry out the cell pressure calibration operation of corresponding component.Individually can also only be passed according to test maintainer pattern setting
Sensor pressure calibration.
It is above-mentioned to carry out Stress control test, to realize that the process of diagnosis of brake failure includes dynamic detection and static inspection
Survey, wherein dynamic detection is realized using intelligence test algorithm：According to the input of brake system, brake system model and current
System mode, using the state of Kalman filtering algorithm real-time estimation brake subsequent time, and detects number by it with real-time
According to being contrasted, rational failure error-detection threshold is set, finally all parts is realized with online fault detect, and generate
Examining report.There is noise jamming during for brake system model uncertainty and system operation, the algorithm introduces karr
Graceful filtering algorithm improves fault diagnosis accuracy rate of the system under the state that is disturbed.Kalman filtering algorithm is as follows：
1. brake system model state transition equation：
X (k)=A*X (k-1)+B*U (k)+Q (k)
Y (k)=H*X (k)+R (k)
2.Kalman processes：
(1) forecast updating：
X (k | k-1)=A*X (k-1 | k-1)+B*U (k)
(2) covariance of X (k | k-1)：
P (k | k-1)=A*P (k-1 | k-1) * A '+Q (k)
(3) kalman gain Kg：
Kg (k)=P (k | k-1) H '/(H*P (k | k-1) * H '+R (k))
(4) predicted state updates：
X (k | k)=X (k | k-1)+Kg (k) * (Y (k)-H*X (k | k-1))
(5) covariance of X (k | k)：
P (k | k)=(I-Kg (k) * H) P (k | k-1)
I is unit matrix.
X (k) represents the system mode at k moment, and U (k) represents the system input at k moment, and Q (k) is system noise；R (k) generations
Table measurement noise, Y (k) represents the system output at k moment, and A, B, H are the parameter matrix of system；X (k | k-1) represent according to k-1
The system mode at the k moment of the system state estimation at moment, X (k-1 | k-1) represents k-1 moment for estimating according to the k-1 moment
System mode, P (k | k-1) represents the covariance of X (k | k-1), and P (k-1 | k-1) represents the covariance of X (k-1 | k-1), Kg (k)
Represent kalman gain, X (k | k) represents the status predication at k moment and updates, P (k | k) represents the covariance of X (k | k), and I is unit
Matrix.
The detected value of discreet value X (K) and sensor finally according to Kalman filtering confirms whether system breaks down.
