Embodiment Construction

[0007] As described in Book 1, a concrete mixing plant control system described in the embodiment of the present invention is constructed, and its system is realized by the system hardware structure and system software design. It is characterized in that the LPC2210 microcontroller is based on a 32 / 16-bit ARM7TDM1-SCPU supporting real-time simulation and embedded tracking, and the software design adopts UC / OS-II, which is more suitable for embedded systems with tight resources. It is specifically implemented according to the following embodiments.

[0008] LPC2210 and interface circuit. The LPC2210 microcontroller is based on a 32 / 16-bit ARM7TDM1-SCPU that supports real-time simulation and embedded tracking. Due to the 144-pin package of the LPC2210, extremely low power consumption, multiple 32-bit timers, 8-way 10-bit ADC, and internal viewing Gates and up to 70 CPI / Os make it especially suitable for automatic control of mixing plants. Among them, 8 channels of 10-bit A / D co...

Abstract

The invention discloses a concrete mixing plant control system construction method, overcomes such defects as weak reliability and unstable communication of a traditional mixing plant control system based on an industrial personal computer and a PLC, and makes up the defects in a traditional control system. An embedded concrete mixing plant control system uses an ARM as a processor and an UC / OS-II as an operation system to provide an economical and practical mixing plant embedded control system. Functionally, the mixing plant functions with a traditional industrial personal computer as core can be totally realized, and the metering, the feeding, the mixing and the discharge of all materials can be automatically and continuously controlled according to given formulas. Meanwhile, the system also has such a series of management functions as browse, inquiry, statistics and printing for data.

Description

technical field [0001] The invention relates to a method for constructing a control system of a concrete mixing plant. Background technique [0002] In the field of control of concrete mixing plants, the current mainstream automatic control system of mixing plants is mainly composed of three parts: industrial computer, operating console and power distribution cabinet. Although this control system can meet the requirements of automatic control of mixing plants, it has the advantages of large volume and high cost. , the shortcomings of unstable communication, with the continuous development of ARM processor applications in the field of industrial control and the increasing popularity of open source embedded multitasking operating systems, the embedded control system combined with the two continues to move towards the traditional The control system with industrial computer as the core poses challenges, so it will be replaced by the embedded mixing plant control system. Conten...
