Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the present invention includes two parts of a master controller module and a wireless communication module, namely:

[0022] The main controller module runs the RJ45 bus protocol and is responsible for calculating the protocol data and performing control functions. The main controller module is composed of a microcontroller and a storage part. The main controller module is the core circuit, which controls the normal operation of the entire system and the realization of various functions. This module is a hardware platform with microcontroller U1 as the core. The storage part is composed of the first ~ second random access memories U2 ~ U3 and flash memory U4, which are respectively connected to the microcontroller U1; the fieldbus industrial Ethernet fieldbus protocol is stored in the flash memory U4; the microcontroller U1...

Abstract

The invention relates to the field of automatic control, and specially relates to a wireless DSP calculator based on a field bus. The wireless DSP calculator comprises two portions of a master controller module and a wireless communication module; wherein the master controller module runs an RJ45 bus protocol; the wireless communication module is used for communicating with other wireless terminals, and provides interlinkages with the Ethernet, and is connected with the master controller module through a USB input module; and the master controller module and the wireless communication module together form a control network of the field bus. By employing the intelligentized control device based on the RJ45 bus, a control function in an industrial field is achieved, terminals or wired connection between the wireless DSP calculator and a control system are / is eliminated, and the cost of the control system is reduced.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a field bus-based wireless DSP calculator. Background technique [0002] Currently, fieldbus and industrial Ethernet technologies are widely used in industrial production. However, due to the complexity of the process industry, wired networks cannot meet the measurement and control requirements in harsh environments, and wireless network technology provides a good solution for this. Therefore, the heterogeneous network control system that integrates wireless network and wired network is an inevitable trend to solve complex process industrial measurement and control. [0003] The concept of industrial wireless technology was first proposed by the US Department of Energy in 2002. Industrial wireless technology is an emerging wireless communication technology for information interaction between devices. It is suitable for use in harsh industrial field environments. It has technical...
