The present invention proposes a two-way pre-tensioned prestressed concrete track slab manufacturing information management system, including: plan progress management module, manufacturing process management module, track slab traceability module, data interface module; said plan progress management module follows track slab Specifications plus track slab type for classification plan management; the manufacturing process management module is used to standardize the entire process of track slab manufacturing; the track slab traceability module is used to provide information on the manufacturing process of track slabs through RFID tags Traceability; the data interface module is used to manage the data interface for communication with the manufacturing equipment of bidirectional pretensioned prestressed concrete track slabs. The present invention promotes the optimization of business processes, the communication and coordination of each level, each department, and each link, the integration of internal and external information, the consistency, filing, query and traceability of data, and improves the work efficiency of each link.

The invention discloses an online non-public fundraising method. A fundraising system of non-public fundraising is built on the internet by building a network platform; accounts are distributed to entities and individuals which are registered in the fundraising system, the fundraising system accounts with different functions and rights are distributed for different types of the entities and individuals such as fundraising people, underwriters and investors, a fundraising system administrator seriously supervises and manages non-public fundraising performed by a fundraising party of a non-public fundraising project through the fundraising system by supervising, controlling and managing the functions and the rights of the accounts, and it is guaranteed that the fundraising party of the non-public fundraising project can only perform non-public fundraising to the qualified investors who are registered in the fundraising system through the fundraising system but not through a way of performing fundraising to the public or performing public publicizing and popularizing to the society; the fundraising system administrator assists relative supervision departments to supervise and manage non-public fundraising of the fundraising part by supervising and managing the fundraising result of non-public fundraising performed by the fundraising part through the fundraising system. The online non-public fundraising method is a method for the fundraising part of the non-public fundraising project to perform fundraising, and therefore the feasibility of performing non-public fundraising by the fundraising part of the non-public fundraising project through a network is achieved.

The invention belongs to the field of video processing and pattern recognition, and in particular relates to a video-based automatic detection method for railway wagon spills, which is based on background modeling-based moving target detection and neural network-based target recognition algorithms. Its background modeling-based moving target detection and neural network-based target recognition algorithm include the following steps: Step 1. Acquire video; Step 2. Establish the histogram gradient feature model of the train running part; Step 3. Use background modeling technology to extract Suspected spills; Step 4. Recognition of suspected spills based on neural network (ANN). The invention realizes the automatic detection and recognition of the spilled objects of the truck under the state of the train running at high speed, has high detection accuracy and low misclassification rate, and the fast detection speed also satisfies the actual engineering needs.

The invention discloses a method of raising a colloidal tin ore dressing recovery percentage. The method specifically comprises the following steps: 1) tinstone and colloidal tinstone are subjected to ore grinding treatment separately and then are mixed according to a certain proportion, mixed powder is screened after the mixing, then screened powder is soaked in mixed acid of hydrochloric acid and hydrofluoric acid for impurity removal, and after the impurity removal is completed, the mixed powder is washed and dried; 2) the mixed powder is subjected to magnetic separation; 3) the mixed powder after the magnetic separation enters a hanging trough type flotator for floatation, during which a NaOH solution or a HCl solution is used to adjust PH of floatation ore pulp to be 3-5, and a collecting agent is added to the floatation ore pulp for preventing colloidal tin from losing; and 4) the mixed powder after the floatation enters a shaking table for gravity separation, and tin concentrate is obtained after the gravity separation. Under the condition that no ore dressing flow is changed, the problem that the colloidal tin ore dressing recovery percentage is low is solved effectively, the economic benefits of an enterprise are improved substantially, and the three rates of ore dressing are raised remarkably.
