Background technique

For users of liquid chromatography separation and purification instruments, the most important thing in the use of instruments and equipment is data, and each piece of usage data is the most precious information. At present, the liquid chromatography separation and purification instruments on the market are lacking in data usage and data security. At present, the liquid chromatography instruments on the market are all single-machine designs. When the instrument is down, the instrument cannot export data from the database by normal means, and cannot import the original historical records to the new machine. It is not conducive to unified search of historical data. The lack of a unified, data-synchronized database leads to the loss of experimental data in the original instrument. Even if the user has backed up the instrument experimental data during normal use, there is still a risk of loss or leakage due to unencrypted data. When the downtime instrument is returned to the factory for repair, the user cannot confirm whether his historical records have been deleted in the old machine. The data security is low, causing users to always worry about the loss or leakage of their data.

Detailed ways

In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

Referring to FIG. 1 and FIG. 2 , a first aspect of an embodiment of the present invention provides a method for networking a liquid chromatograph system, wherein the liquid chromatograph system comprises: a plurality of liquid chromatographs connected to a network, and comprises the following steps:

Step S100, controlling each liquid chromatograph to send the configuration and operation data of other liquid chromatographs that have undergone the first encryption process in the previous data synchronization cycle, wherein the configuration and operation data include: experimental data, user data and historical record data.

In step S100, two data synchronization processes are specifically included, one is a distributed data storage process, and the other is a distributed data request process.

Wherein, please refer to FIG. 3, the specific steps of the distributed data storage process are as follows:

Step S111, controlling the data sending direction of the liquid chromatograph to send the encrypted token, configuration and operation data and data index thereof to the data receiving direction.

Step S112, controlling the data receiver to decrypt and verify the encrypted token to confirm that the data sender is qualified to exchange data.

Step S113, judging whether the configuration and operation data have been stored in the database of the data receiver according to the data index.

Step S114: If yes, then only send the operation success information to the data sender.

Step S115: If not, the configuration and operation data are stored in the database of the data receiver, and an operation success message is sent to the data sender.

In the above process, the instrument data is distributedly stored on each liquid chromatograph in the networking system. Users can access all the data in the network by accessing any instrument through the IPAD on the liquid chromatograph.

For example, if there are five instruments, the distributed storage will store the data of instrument 1 on instrument 1, instrument 2, instrument 3, instrument 4 and instrument 5 respectively, and the data of instrument 2 will be stored on instrument 1, instrument 2, instrument, instrument 4 and instrument 5 respectively, and so on. At the same time, when the data of instrument 1 is stored on all the devices in the network, these five instruments will generate a unique index for this data and save the data access location in the database. According to this solution, as long as there is one instrument online in the network, it will not affect the complete access to the data of the entire network.

Instrument 1 carries the encrypted token, data, and data unique index, and accesses the data receiving interface of online instrument 2 through the HTTP protocol. After receiving the data, instrument 2 decrypts and verifies the token to confirm that it is a networked instrument. According to the unique index of the data given by instrument 1, the database is queried to see if the data exists. If not, the data is saved in the PostgreSQL database. And the data is saved in the database storage location. The data access path is returned through the HTTP protocol to inform instrument 1 that the operation is successful. If the query shows that the data exists, it is only necessary to return the result through the HTTP protocol to inform instrument 1 that the operation is successful. Instrument 1 stores the storage location of this data in the database. Instrument 1 stores the data to all other instruments in the network, and instrument 2 and other instruments store the data to all other instruments in the network according to this process.

In addition, please refer to Figure 4, the specific steps of the distributed data request process are as follows:

Step S121, obtaining the address and data list of the liquid chromatographs in operation in the liquid chromatograph system.

Step S122, selecting a data storage address from among several data storage addresses for the required configuration and operation data based on a polling or random algorithm, and sending an encrypted token and data request information to the liquid chromatograph corresponding to the data storage address.

Step S123, the data sender of the liquid chromatograph verifies the encryption token, and after confirming that the data receiver is qualified for data exchange, sends the configuration and operation data to the data receiver.

Users access data in the LAN intranet system through web pages or IPAD, search for data storage locations through databases and data indexes, and access data through location addresses. If only one instrument is online, the complete data of all instruments in the network can be accessed. The access process is:

The user accesses the networking system address in the LAN, queries historical records, separation methods and other data, and queries the data list. Click Details. The instrument uses the data unique primary key carried in the list, permissions, and whether the instrument is online to query the database for multiple storage addresses of this data. After obtaining multiple storage addresses of the data, one of the addresses is selected according to polling or random algorithms to obtain data to ensure load balancing of system data access. After obtaining the address, the HTTP protocol is used to carry user tokens and data unique primary keys and other parameters to obtain the specified data from the instrument pointed to by the address in the network. This access instrument verifies user permissions through tokens, queries specified data based on the data unique primary key, and returns the data to the user's IPAD or web page connected to this LAN for display. Distributed data ensures the integrity of user data even after a less random instrument crash. It greatly guarantees the security and integrity of user data.

After the first complete data receiving and backup process is completed, in order to reduce the amount of data transmission in the system network and reduce the network data load, the liquid chromatograph first determines whether its own data has changed before sending its own configuration and operation data and receiving the configuration and operation data of other liquid chromatographs. If the configuration and operation data have changed, it will be sent to other liquid chromatographs in the system network; if there is no change, data will not be sent, so as to achieve the purpose of reducing the data flow load in the system network.

In addition, the above purpose of reducing network traffic load can also be achieved by each liquid chromatograph determining whether to send data to other liquid chromatographs based on its own configuration and operating data changes. During the above data storage and access process, if the amount of data to be synchronized is large, the HTTP communication protocol can be used for data transmission. If the amount of data is small, the UDP communication protocol can be used for transmission.

Data encryption, interconnection and synchronization are realized among several liquid chromatographs in the above-mentioned liquid chromatograph system, and continuous use of equipment and data security are achieved through networking. Any liquid chromatograph data in the networking is backed up in the entire networking system. When the device is connected to the networking, the device spontaneously initiates the data synchronization process to synchronize data. After the networking is completed, the entire network uniformly manages the user information and data resources of each device.

Specifically, the first encryption process is to encrypt and decrypt the configuration and operation data based on the AES encryption method. Among them, the AES encryption method is only a preferred implementation method for transmitting configuration and operation data between each liquid chromatograph connected to the network. Other encryption methods fall within the protection scope of the technical solution of this application as long as they can achieve secure transmission of data encryption and decryption between two liquid chromatographs in the network.

Furthermore, the liquid chromatography system networking method also includes:

Step S321, obtaining a network status detection signal based on a liquid chromatograph.

Step S322, when the liquid chromatograph does not detect a network status detection signal within the first preset time, it is determined that the liquid chromatograph is in an off-network state, its operating state is locked, and a second encryption process is performed on the configuration and operating data stored inside the liquid chromatograph.

Optionally, the first preset time length is 20min-30min. If the liquid chromatograph does not detect the network status detection signal within 20min-30min, it is determined that there is a network connection problem with the system network or it is disconnected from the network. If it is a network connection problem, after re-receiving the network status detection signal, the configuration and operation data of the liquid chromatograph are re-sent according to the data synchronization cycle, and the configuration and operation data regularly sent by other liquid chromatographs are received. If the liquid chromatograph is offline, the liquid chromatograph performs a second encryption process on its internal configuration and operation data to ensure the security of the internal data of the liquid chromatograph, prevent the loss of hardware from causing the leakage of the configuration and operation data stored internally, and ensure the data security of all devices in the overall liquid chromatograph system.

Specifically, the second encryption process is to encrypt the configuration and operation data in the liquid chromatograph based on the device code and the device MAC address of the liquid chromatograph through the md5 encryption algorithm.

Furthermore, after step S322, the liquid chromatography system networking method further includes:

Step S323, when the liquid chromatograph fails to detect the network status detection signal within the second preset time, it counts the number of consecutive errors in the user login information it receives;

Step S324: when the number of consecutive errors in the received user login information exceeds a first preset number, the liquid chromatograph is controlled to delete the configuration and operation data stored therein.

Optionally, the second preset time is 60min-120min. In order to further improve data security and prevent data loss from causing major losses, if the liquid chromatograph does not detect a network signal within 60min-120min of being offline, it will start to verify the received user login information. If the wrong user login information is entered continuously for the first preset number of times, all configuration and operation data stored in it will be deleted, and the internal storage area will be repeatedly read and written to achieve complete data clearing, avoiding data leakage of all configuration and operation data of all liquid chromatographs in the system network due to loss or theft of hardware devices. The above data processing protection and processing method ensures data security of all devices in the system network and greatly improves the system security of the liquid chromatograph system.

From the above, we can see that: if a liquid chromatograph is disconnected from the system network for some reason (failure or human), its data will be automatically encrypted and can be deleted remotely (authorized, or automatically, etc., preset deletion conditions). Each liquid chromatograph will send online status to the system every 5 minutes through the UDP communication protocol, and the system will also have corresponding response feedback to inform the instrument that the message has been received. If the system does not receive the information sent by the liquid chromatograph for 1 hour, it is judged that the liquid chromatograph has been disconnected from the network. At this time, the system will execute the process of disconnecting the liquid chromatograph from the network. The process includes: Step 1. Gray out the status of the liquid chromatograph that is disconnected from the network. Step 2. Lock the data of the liquid chromatograph in the network, and only the administrator user can operate it. After being turned on, the liquid chromatograph that has been disconnected from the network sends information to the networking system through the UDP communication protocol. If no response is received from the networking system for 20 minutes, the instrument is locked, the liquid chromatograph account is locked, and the database data block is zip encrypted. The secret key is the key calculated by the md5 encryption algorithm using the device number, instrument MAC address and other information. This realizes the overall encryption of the instrument data and ensures that the instrument data cannot be cracked. The user can only use the liquid chromatograph normally by connecting it to the external network, connecting to the liquid chromatograph through the network and unlocking it.

In addition, when any machine fails in the network, the user can remove the machine from the network system and delete all data on the machine at the same time. The faulty instrument will be returned to the factory for repair, and no user data will be left in the instrument. After the new instrument is connected, the new device can automatically restore all data and configurations of the faulty device when connected to the network, and it will be seamlessly connected and continue to work like the original device. In this way, the uninterrupted use of the user's equipment and the data security of the faulty off-network equipment are ensured.

Furthermore, the first encryption process is to encrypt and decrypt the configuration and operation data based on the AES encryption method.

Specifically, the liquid chromatography system networking method also includes:

Step S410, verifying the identity information of the liquid chromatograph newly connected to the system network, the identity information including: device type, device code, device firmware version number and device networking information.

Step S420, after confirming the identity information of the liquid chromatograph newly connected to the system network, control the liquid chromatograph newly connected to the system network to send configuration and operation data to other liquid chromatographs in the system network according to the data synchronization cycle.

When a new liquid chromatograph is connected to the system network and its network signal is detected, the identity information of the new liquid chromatograph is verified and reviewed. If the identity authentication is passed, the new liquid chromatograph connected to the system network is controlled to send configuration and operation data to other liquid chromatographs in the system network according to the data synchronization cycle.

In addition, the device management unit periodically detects the liquid chromatograph connected to the network. When a newly connected liquid chromatograph is detected, the verification information sent by the liquid chromatograph is received and the information is verified. The verification information includes: device type, device code, device firmware version number and device networking information. Further, the configuration and operation data are encrypted, including: encrypting the configuration and operation data based on the device code and device MAC address of the liquid chromatograph using the md5 encryption algorithm.

For newly added liquid chromatographs in the system, other liquid chromatographs will promptly identify them, and after confirming their legitimacy, they will establish data connectivity, thereby building a security barrier for user accounts. The liquid chromatograph is connected to the local area network via a network cable or WIFI, and will send verification information to the system control module via the UDP communication protocol. The verification information includes: device type, device code, device firmware version number, and device networking information. The networking system will verify the verification information, verify whether the firmware versions of both parties are consistent, verify whether the machine is in other networks, and verify whether the machine type can be added to this network. After the networking system completes the verification, the connected instrument will be added to the system network by default.

After data synchronization is completed, the liquid chromatograph will periodically query and synchronize incremental data. After the devices in the network complete data synchronization, users can remotely create instrument separation tasks through the various functional units of the system control module, view and use the separation methods extracted by the instruments in the network, view all instrument history records in the network, understand the use of separation columns in the network, and uniformly manage instrument login users. Users can remotely view the history records of instruments in the network, create separation tasks, audit instrument usage, improve work efficiency and instrument utilization; in addition, data encryption in the network also ensures the data security of users when accessing content such as historical records of networked instruments.

Correspondingly, a third aspect of an embodiment of the present invention provides a computer-readable storage medium on which computer instructions are stored. When the computer instructions are executed by a processor, the above-mentioned liquid chromatography system networking method is implemented.
