[0099] The preliminary review and detailed review functions of the present invention are completed by encapsulating TreeView, TableView, ImageView, Pagination, and Button. Users can associate the page numbers of uploaded commercial bids and technical bids according to the review items, which improves the convenience of preparing bidding documents.

[0100] The embodiment of the present invention provides a simple and secure offline bidding system based on the JAVAFX framework, which also includes:

[0101] An encryption subsystem for generating offline bidding documents based on two methods: using digital signatures or not using digital signatures;

[0102] The encryption subsystem generates offline bidding documents based on two methods: using digital signatures or not using digital signatures, including:

[0103] When the bidding documents are completed and digital signature is used, install the third-party digital signature client and call it for signing;

[0104] After the signature is completed, use the digital signature PIN code to verify;

[0105] After the digital signature PIN code verification is completed, the encryption operation is performed using the offline bidding tool;

[0106] When the bidding document is prepared and no digital signature is used, the bidder's custom password is obtained based on the Password component for encryption, and the encrypted password is backed up locally to the bidder.

[0107] The working principle and beneficial effects of the above technical solution are:

[0108] The offline bidding of the present invention is divided into bidding documents generated under two conditions: using digital signature or not using digital signature. When using digital signature, it is necessary to install a third-party digital signature client. After the bidding document is prepared, the third-party digital signature client is called to sign. After the signing is completed, the digital signature PIN code is used for verification. After the verification is completed, the offline bidding tool is used for encryption. When the digital signature is not used, after the bidding document is prepared, it is encrypted with a user-defined password based on the Password component, and the encrypted password is backed up to the user's local.

[0109] A simple and secure offline bidding system based on JAVAFX framework, further comprising:

[0110] The automatic detection and update subsystem is used to obtain the bidder's local offline tool version when the bidder is online, and at the same time, obtain the latest version of the offline tool, and automatically detect and update according to the local offline tool version and the latest version of the offline tool.

[0111] The working principle and beneficial effects of the above technical solution are:

[0112] The present invention detects the version of the local offline tool according to the system version when connected to the network, and compares the version of the offline tool according to the version of the bidding document when offline. If the version is lower, an update is prompted, and the higher version tool is downward compatible with the lower version.

[0113] In one embodiment, automatically detecting and updating based on the local offline tool version and the latest offline tool version includes:

[0114] When a version upgrade is detected based on the local offline tool version and the latest version of the offline tool, an upgrade item is obtained; wherein the upgrade item is: an upgraded function or a patch of the local offline tool version;

[0115] Try to obtain the local bidding document production process; the local bidding document production process is: the production process of the bidding document produced in real time by the bidding tool of the local offline tool version;

[0116] If the acquisition attempt fails, directly upgrade the local offline tool version to the latest offline tool version;

[0117] If the acquisition attempt is successful, the production process node is determined according to the local bidding document production process; wherein the production process node is: the production process stage of the real-time bidding document, such as: the quotation stage;

[0118] Calculate the node stagnation time of the production process node; where the node stagnation time is: the length of time the production process stops at the corresponding stage;

[0119] If the node stagnation time is greater than or equal to the preset node stagnation time threshold, the corresponding production process node is used as the target production process node; wherein the preset node stagnation time threshold is manually preset, for example: 3 days;

[0120] According to the target production process node, determine the bidder inquiry node; wherein the bidder inquiry node is: the target production process node corresponding to the bidder's communication node of the bid document;

[0121] Obtain the reply information of the inquiry bidder node; the reply information includes: which step of the bidding tool has a problem and the manual intervention strategy, for example: the tax rate calculation is incorrect, and the manual intervention strategy is: manually enter the calculated tax rate;

[0122] According to the reply information, the target functional component is determined; wherein the target functional component is: the functional component that causes the delay of the bidding process;

[0123] Obtaining the correlation value between the target functional component and the upgrade project; wherein the correlation value represents the ability of the upgrade project to solve the defects of the target functional component corresponding to the manual reply, and the higher the solving ability, the greater the correlation value;

[0124] If the correlation value is greater than or equal to a preset correlation value threshold, then obtaining the first bidding document corresponding to the corresponding target production process node; wherein the preset correlation value threshold is manually preset;

[0125] According to the reply information, the remaining processing time of the first bidding document is determined; wherein the remaining processing time is: the total time spent after manually intervening in the steps where the bidding tool has problems to assist in processing and then using the tool to complete the preparation of the bid document for the first bidding document;

[0126] Obtaining a first installation processing time duration corresponding to the first bidding document for the upgrade project; wherein the first installation processing time duration is: the total time duration for upgrading the upgrade project and then reusing the upgraded tool to prepare the bid document for the first bidding document;

[0127] If the remaining processing time is longer than the first installation processing time, the local offline tool version is upgraded to the latest version of the offline tool and the first bidding document is reprocessed;

[0128] If the remaining processing time is less than or equal to the first installation processing time, the bidder will assist in completing the first bidding document processing and then upgrade the local offline tool version to the latest version of the offline tool.

[0129] The working principle and beneficial effects of the above technical solution are:

[0130] When updating the local offline tool version online, not all situations are suitable for immediate updating. For example, when a new version is detected, the local offline tool is being used. Therefore, when a version upgrade is detected, an attempt is made to obtain the local bidding document production process. If the attempt fails, it means that the local offline tool is not in use and can be directly upgraded. If the attempt is successful, the production process node of the local bidding document is determined, the length of time the production process stops at the corresponding stage (node ​​stagnation time), and the target production process nodes whose node stagnation time is greater than or equal to the preset node stagnation time threshold are screened; the communication node of the bidder of the bidding document corresponding to the target production process node is connected to obtain relevant replies, and the cause of the process delay and the corresponding target functional component that caused the delay in the bidding process are determined; the correlation value between the target functional component and the upgrade project is calculated. If the correlation value is greater than or equal to the preset correlation value threshold, it means that the version upgrade can optimize the existing problems, but it involves the issue of whether to optimize first and then re-produce the first bidding document, or to manually process it first and then optimize it. Therefore, according to the reply information, the remaining processing time of the first bidding document is determined, and at the same time, the first installation processing time of the upgrade project corresponding to the first bidding document is obtained; if the remaining processing time is greater than the first installation processing time, the local offline tool version is upgraded to the latest version of the offline tool and the first bidding document is reprocessed, otherwise, manual processing is performed first and then the update is performed, which improves the rationality of version updating when local bidding documents are produced during the update.

[0131] In one embodiment, if the remaining processing time is longer than the first installation processing time, the local offline tool version is upgraded to the latest version of the offline tool and then the first bidding document is reprocessed, including:

[0132] The bidding document other than the first bidding document among the bidding documents corresponding to the production process node is used as the second bidding document;

[0133] Obtaining a second installation processing time duration corresponding to the second bidding document of the upgrade project; wherein the second installation processing time duration is: the total time duration of re-making the second bidding document after the version upgrade;

[0134] If the second installation processing time exceeds the processing time threshold of the second bidding document, a bidding document-importance value comparison library is obtained; wherein the processing time threshold is manually preset; the bidding document-importance value comparison library is manually preset, and includes one-to-one corresponding bidding documents to be produced and importance values;

[0135] Determine the first important value sum according to the first bidding document and the bidding document-important value comparison library; wherein the first important value sum is: the sum of the important values ​​corresponding to the first bidding document;

[0136] Determine the second important value sum according to the second bidding document and the bidding document-important value comparison library; wherein the second important value sum is: the sum of the important values ​​corresponding to the second bidding document;

[0137] If the sum of the first important values ​​is greater than the sum of the second important values, the first bidding document is reprocessed after the local offline tool version is upgraded to the latest version of the offline tool;

[0138] If the sum of the first important values ​​is less than or equal to the sum of the second important values, the second bidding document is prepared and after the bidder assists in processing the first bidding document, the local offline tool version is upgraded to the latest version of the offline tool.

[0139] The working principle and beneficial effects of the above technical solution are:

[0140] When performing version update, the impact of the update on the normal bidding document production process also needs to be considered. The present invention determines the second bidding document (normal bidding document production process), determines the time taken to produce the second bidding document after the version upgrade (second installation processing time), and when the second installation processing time exceeds the processing time threshold of the second bidding document, it means that if the version is updated, the production process of the second bidding document will be delayed, and if the version is not updated, the production process of the first bidding document will be delayed. Therefore, a bidding document-important value comparison library is introduced to respectively determine the first important value and the second important value corresponding to the first bidding document and the second important value and the second important value, when the first important value and the second important value are greater than the first important value, it means that the first bidding document has a higher priority, and the version upgrade is performed first. After the upgrade is completed, all bidding documents (the first bidding document and the second bidding document) are re-produced using the new version tool; if the first important value and the second important value are less than or equal to the second important value, the second bidding document is waited for to be produced and the bidding personnel assist in the processing of the first bidding document before the version upgrade is performed, which further improves the rationality of determining the timing of tool version upgrade.
