Based on same inventive concept, the embodiment of the present invention additionally provides a kind of communication message applied to said detecting system Detection method, refering to shown in Fig. 3, the flow of the detection method of communication message is as follows:
Step 300:Receive the first communication message that equipment under test is sent.
In the specific implementation, after detecting system and equipment under test complete physical connection and upper electricity, you can triggering communication report The testing process of text, now, equipment under test can send the first communication message to detecting system, and detecting system receives tested set After the first communication message that preparation is sent, you can first communication message is detected.
Step 301:Judge whether the first communication message meets the standard requirement pre-set for the first communication message. During specific implementation, following two conditions can be included but is not limited to for the standard requirement that the first communication message is pre-set:(1) The standard traffic message matched with the first communication message is found in the standard traffic message store pre-established.(2) first Time difference between the reception time of communication message and the transmission time of upper second communication message is not more than predetermined threshold value.
Step 302:Based on judged result, determine whether the first communication message detects and pass through.
In the specific implementation, it is understood that there may be but it is not limited to following two situations:
The first situation:Detecting system is based on judged result, assert that the detection of the first communication message passes through, the even first communication Message meets following two conditions simultaneously, then detecting system can be assumed that the detection of the first communication message passes through:(1) pre-establishing Standard traffic message store in find the standard traffic message matched with the first communication message;(2) first communication messages Time difference between reception time and the transmission time of upper second communication message is not more than predetermined threshold value.
For example:In charging handshake phase, by sending handshake message between electric automobile and charging pile, communication link is realized Connect, below using charging pile as equipment under test, and the first communication message is the BHM handshake message that equipment under test (i.e. charging pile) is sent Exemplified by illustrate.
Detecting system is received after BHM handshake message, however, it is determined that BHM handshake message meets following two conditions simultaneously, then It can be assumed that the detection of BHM handshake message passes through:
Condition 1:The standard matched with BHM handshake message can be found in the standard traffic message store pre-established BHM handshake message.
Condition 2:The time difference received between time and the transmission time of a upper CHM handshake message of BHM handshake message No more than 5 seconds (i.e. predetermined threshold value).
The first situation:Detecting system is based on judged result, assert that the detection of the first communication message does not pass through, even first leads to Believe that message meets any one following condition, then detecting system can be assumed that the detection of the first communication message does not pass through:(1) advance The standard traffic message matched with the first communication message is not found in the standard message storehouse of foundation;(2) first communication messages With the standard traffic message mismatch found in the standard message storehouse pre-established;During the reception of (3) first communication messages Between time difference between the transmission time of upper second communication message be more than predetermined threshold value.
For example:Continue to use the example above, detecting system is received after BHM handshake message, however, it is determined that BHM handshake message meet with Any one lower condition, the then it can be assumed that detection of BHM handshake message does not pass through:
Condition 1:The standard matched with BHM handshake message is not found in the standard traffic message store pre-established BHM handshake message.
Condition 2:BHM handshake message and the standard BHM found in the standard traffic message store pre-established shake hands report Text is mismatched.
Condition 3:The time difference received between time and the transmission time of a upper CHM handshake message of BHM handshake message More than 5 seconds (i.e. predetermined threshold value).
Further, can also be by the first communication message and the after detecting system is completed to the detection of the first communication message The testing result of one communication message is exported to the control device such as computer or other smart machines, and specifically, detecting system can So that after it is determined that the detection of the first communication message is obstructed, the first communication message and the first communication message to be detected to the detection not passed through As a result export to control device, now, control device can make further inspection for the first communication message, that is, judge that first leads to Whether letter message does not meet the standard requirement pre-set for the first communication message really, if control device assert that first communicates Message does not meet the standard requirement pre-set for the first communication message really, and control device can be shown for table to user The prompt message that the first communication message is not inconsistent standardization requirement is levied, now, user can be according to the prompt message on the control device Input corresponding operational order, control device is got after the operational order that user inputs for the first communication message, can be by The operational order is back to detecting system, and detecting system is received after the operational order of control device return, can be based on the operation Instruction performs corresponding operating;If the communication message of control device identification first meets what is pre-set for the first communication message really Standard requirement, control device can return to corresponding operational order, detection system directly against the first communication message to detecting system System is received after the operational order of control device return, can perform corresponding operating based on the operational order.
For example:Assuming that detecting system assert that the detection of BHM handshake message does not pass through, then detecting system will can be received The test result that BHM handshake message and the test of BHM handshake message do not pass through is sent to computer (i.e. control device), and computer can To make further detection for BHM handshake message, if computer assert that BHM handshake message is not inconsistent standardization requirement really, calculate Machine can show that one is used to characterize the prompt message that the test of BHM handshake message does not pass through to user, and now, user can calculate Corresponding operational order is inputted on machine, such as, exits test instruction, the test of exiting that computer gets user input is instructed Afterwards, this is exited into test instruction to send to test system, what test system received that computer issues exits after test instruction, can Directly exit the testing process of communication message.If computer assert BHM handshake message meet standard requirement, computer can directly to Test system issues continuation and tests instruction, and test system is received after the continuation test instruction that computer is issued, continued executing with logical Believe the testing process of message.
Preferably, in order to realize that the abnormal conditions diagnostic function to equipment under test detects that test system is right During each first communication message that equipment under test is sent is detected, various exception messages can also be generated, are often generated In the case of a kind of exception message, exception message is sent to equipment under test.In the case, equipment under test can be to exception message The abnormal conditions of sign are diagnosed, and in the form of error message return diagnostic result, so, if test system receive by The error message that the abnormal conditions that measurement equipment is characterized to exception message are returned after diagnosing, can be it is determined that error message be characterized Diagnostic result it is consistent with expected diagnostic result in the case of, assert that equipment under test characterizes abnormal conditions diagnosis nothing to exception message By mistake.Certainly, test system can also by control the second communication message the transmission time, triggering equipment under test to second communication report Text carries out overtime diagnosis, and specifically, test system can not send the second communication message, or, delay sends second and communicated Message (wherein, will send the second communication message after predetermined threshold value and regard as the second communication message of delay transmission), in this feelings Under condition, equipment under test needs to return to the error message of a sign time-out error, so, and test system can be with according to whether receive The error message of the sign time-out error returned to equipment under test, or, the false alarm returned according to the equipment under test received Whether text characterizes time-out error, to assert that diagnosis of the equipment under test to time-out error whether there is mistaken diagnosis.
