Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] The program is written in C language, and the specific functions and implementation methods are as follows:

[0025] exist figure 1 Among them, the main program first reads the default parameter data pre-stored in the electronic disk and initializes the IP network interface and the default sensor type data according to the parameter data; the parameter data includes at least: IP address, subnet mask, gateway address, sensor input The output type and the range of the sensor may also include the production information of the sensor.

[0026] Then the main program begins to assign subtasks, and this program assigns multiple subtasks, including display subroutines, data processing subroutines, web server operation subroutines and FTP (File Transfer Protocol) operation subroutines. According to the priority and processing time of each subtask, a priority ...

Abstract

This invention discloses a method for seamlessly cut-in an adaptive sensor to Internet realized on a Net Box platform. First of all, a default parameter device pre-stored in the storage medium is fetched and input and output volume kinds of the sensor and its range are corrected on-line then to send the output signal into a microcontroller after modulus conversion. The microconroller receives tasks from the sensor or Internet including interruption, display, data process, web-page server and process them according to stipulated priorities, a Ftp server subtask is also included. This invention is a three-layer structure: an internetwork layer provided communication to different hosts on Internet, a transport player responsible for communication between two processes and an applying layer providing service for users' apply process.

Description

technical field [0001] The invention is applied to the field of computer network peripheral equipment, in particular, the invention relates to a method for making various sensors adaptively and seamlessly connected to the Internet. Background technique [0002] In the field of industrial automation, there are a large number of instruments and equipment that collect physical quantities such as pressure, flow, displacement, and temperature from industrial sites. These physical quantities are converted into electrical quantities by various sensors such as temperature sensors, pressure sensors, and displacement sensors. The signal is processed and sent to the host device through the digital interface. A variety of field bus forms have thus been produced, such as Profibus, CAN, and FF (Foundation Fieldbus) and so on. These bus forms have been widely used in field bus control systems to form a digital, two-way, multi-branch communication network that transmits various sensor info...
