The invention provides an assembly-line automatic manufacturing technology for a pre-stressed concrete track board unit by a pre-tensioning method. Traction equipment drives a model to flow on a track according to a time beat, wherein the time beat is working time of each station; the model bears tensioning stress, and all the stations are lined up on an assembly line and work together at the same time; and the quality and the working progress of each station are controlled by a sensor, and each station is commanded by a central control system, so that the operation of the whole system is controlled. Compared with a matrix production method, the assembly-line automatic manufacturing technology has the advantages that temporary components such as a tensile pedestal are eliminated, the model turnover rate is increased by 50 percent, the area of a factory is reduced by 30 percent or above, and the number of workers is reduced by 50 percent or above. The production process fulfills the aims of full-automatic control, informationalized transmission of key data, remote monitoring, and relocation and quick installation of all sets of equipment according to engineering requirements.

The invention discloses a system and a method for turning a handheld mobile terminal into a self-service ordering terminal. The method comprises the steps that: an encrypted two-dimensional code is generated in the system according to a seat number, and the seat number, the two-dimensional code and an image-text instruction manual are printed together and placed on a corresponding dining table; a user scans the two-dimensional code after being connected to WIFI, and the system analyzes the two-dimensional code to find the corresponding seat number; a verification code is required when the two-dimensional code is scanned for the first time, an MAC address of the mobile terminal is recorded into the system if the verification code is correct, and the mobile terminal can be used for ordering on the dining table as long as an MAC addresses recorded by the system is consistent with the MAC address of the mobile terminal after login. The invention further discloses an ordering system based on a fixed terminal distributed management system.
