As shown in figure 1, the loading module of the automatic verification system puts the HPLC module to be detected into the tray, the tray carrying the HPLC module passes through the conveying line, after the appearance detection is completed through the appearance detection device, the tray is continuously circulated to the multifunctional verification bin of the HPLC, the bin is full, the copying controller arranged in the multifunctional verification bin is triggered to start, establish connection and detect, after all the HPLC modules are detected, the industrial personal computer starts to upload data, then the tray is circulated out from the multifunctional verification bin, and the next detection is continuously carried out.

The invention relates to a device and a method for rapidly detecting an HPLC (high performance liquid chromatography) module based on a copy controller, wherein the copy controller comprises six modules, namely an initialization module, a communication initialization module, a detection module, a communication initialization response module, a detection response module and a detection response judgment module. The initialization module initializes parameters such as an MAC address, a working frequency band, an STA (short for station HPLC) address, a reading object and the like. The communication initialization module establishes communication connection with the detection body before starting to send the message. The detection module may send a specific detection message according to a parameter set or initialized by a user, where the detection message does not conflict with an existing HPLC protocol. And the communication initialization response module receives the communication initialization message (reading frequency offset) and feeds back the frequency offset value to establish communication connection. And the detection response module reads the STA related parameters after receiving the specific detection message and sends the specific detection response message. The detection response judging module analyzes and judges whether the response message is correct or not according to the received detection response.

The initialization module is used for initializing the copy controller, setting the MAC address and the working frequency band of the copy controller, and using a set value if a user sets the STA address and the reading object of the HPLC module; if the user is not reset, the original default value is adopted.

The communication initialization module sequentially sends frequency offset reading frames from the frequency band 0 to the frequency band 3 until correct frequency offset signals are read to establish communication connection. The frequency offset reading frame is expanded on the basis of the variable region of the original protocol SACK.

And the detection module issues a detection message according to the set STA address and the detection parameters. The detection message multiplexes the meter reading message of the HPLC protocol, the detection message expands a plurality of parameters to be distinguished from the normal HPLC meter reading message, and the APDU part continues to use the 645 protocol and can read the STAID, the meter reading and the like.

The APDU, MAC frame header and frame control part of the detection message HPLC protocol are optimized, original protocol parameters are multiplexed, but different special values are set, so that a copy controller detection mode is formed, and the purpose of realizing copy controller detection by being compatible with the original HPLC protocol is achieved. The detailed extended parameters include source TEI and original source TEI, destination TEI and original destination TEI, network identification NID, STA address supporting only long MAC frame and APDU carrying planned detection, and parameters (e.g. chip ID, data identification, etc.).

And after receiving the communication initialization message, the communication response module sends frequency deviation according to the actual frequency deviation value, so as to establish connection with the copy controller. The message is detailed in a communication initialization module.

And after receiving the detection command, the detection response module distinguishes and judges whether to detect the message according to the detection mark of the copy controller, and if so, the detection response module directly reads the content of the APDU. If the MAC address of the module is the MAC address, a detection response message is reported after the parameters are read, the message is multiplexed with an HPLC protocol, a reading controller detection mark is set in the message parameters to be distinguished from a normal reading controller, and the detection content continues to use a 645 protocol.

And after the detection response module sends a detection message to the STA, whether the detection is carried out by the copy controller is identified according to the APDU, the MAC frame header and the special identifier of frame control, and if the detection is carried out by the copy controller, the STA address of the APDU part is continuously analyzed. After the detection response judging module receives the response message, if the copy controller detects the response message, whether the detection response parameter is correct is continuously judged, if the detection response parameter is correct (the chip ID is matched with the database), the STA module is normal, otherwise, the STA module is abnormal, and one detection is finished.

The message used by the invention has no conflict with the HPLC protocol, so the invention is also suitable for troubleshooting of engineering field modules and the like.

The detection method comprises the following steps:

the following describes in detail the detection method based on the copy controller proposed by the present invention with reference to fig. 2:

step 1, after the connection is finished according to the figure 3, the copy controller is powered on, and an MAC address, a frequency band, a detection MAC address and parameters are set.

And 2, before the meter reading message is sent, the meter reading controller firstly calls a communication initialization module to establish contact with the STA. The copy controller can sequentially send frequency offset reading frames on the frequency bands of 0-3, and the frequency offset reading frames are expanded on the basis of the variable region of SACK of the original protocol.

TABLE 1 SACK frame variable region

Expanding the SACK frame expansion frame type, wherein 01 represents reading frequency offset, and 02 represents feedback frequency offset; the detailed expansion is as follows:

TABLE 2 read frequency offset extension frame variable region

And 3, after receiving the frequency offset reading frame, the STA identifies that the frequency offset reading frame is detected by the copy controller according to the APDU, the MAC frame header and the special identifier of frame control, and feeds back the frequency offset according to the actual value to send a frequency offset feedback frame, thereby establishing connection with the copy controller.

TABLE 3 frequency offset feedback extension frame variable region

Step 4, according to the conditions set in step 1, the copy controller forms a message, and key parameters of the message are detected as follows:

the invention optimizes APDU, MAC frame head and frame control part of the detection message HPLC protocol, reuses the original protocol parameters, but sets different special values, thereby forming the detecting mode of the copy controller, achieving the purpose of realizing the detection of the copy controller by being compatible with the original HPLC protocol. The detailed extended parameters are as follows:

a source TEI and an original source TEI;

a destination TEI and an original destination TEI;

a network identification NID;

only long MAC frames are supported.

The APDU carries the STA address and parameters (e.g., chip ID, data ID, etc.) to be detected.

And 5, after receiving the detection message, the STA identifies that the detection is performed by the copy controller according to the APDU, the MAC frame header and the special identifier of the frame control, and continuously analyzes the STA address of the APDU part.

And 6, if the MAC address carried in the APDU is not matched with the MAC address of the module, directly discarding the message.

And 7, if the MAC addresses are matched, reading the response parameter values and detecting the response message. The constitution of the response message is similar to the message in step 2, the APDU, the MAC frame header and the frame control part set special values, and other parts continue to use the original protocol.

And 8, after receiving the response message, if the copy controller detects the response message and continuously judges whether the detection response parameter is correct, if so, the chip ID is matched with the ID in the database, the STA module is normal, otherwise, the STA module is abnormal, and one detection is finished.

The above flow is only a flow description based on one STA, and multiple parameters of multiple STAs can be copied in actual use, thereby improving efficiency. From the practical point of view, most of the 2 parameters of 5 STAs detected at a time have the best effect under the physical connection. The detection of 30 STA modules is actually controlled within 25 seconds.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; it is obvious as a person skilled in the art to combine several aspects of the invention. And such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
