Through the transplant and development of an embedded TCP/IP protocol stack LwIP and the Web server, functional requirements for the remote motor control system based on the eCos and the Web server are finally realized. Compared with the prior art, since automatic production and network-based management can be realized by the embedded server in the production field according to the utility model, the production efficiency is improved. And the remote motor control system based on the eCos and the Web server has advantages of high stability, good real-time property, low cost and the like.
Description
Technical field
The utility model relates to the remote motor control field, particularly a kind of remote motor control system based on eCos and Web server.
Background technology
Along with popularizing fast of automated system, these control system are the control appliance state in real time, for the automatic operating of field apparatus provides effectively Means of Ensuring.But because the employing of most industrial control system is traditional control model, the manager of production whenever and wherever possible remote control equipment moves.The motor remote control technology integrates control technology and the network communications technology, has realized the comprehensive functions such as remote access, control and data communication to motor device.Because this technology so that information network has directly embedded in the field control network of traditional industry equipment, meets the decentralized trend of industrial equipment, so in the Internet communications field advantageous advantage is arranged.
Be applied to step motor control based on eCos and Web server tele-control system and have conventional on-site and control not available various requirement, its main characteristics are as follows: real-time, fail safe, extensibility.In practical application in industry, the mode of PC control mainly is to communicate with serial ports such as RS232, RS485, but command range is shorter.In addition, some schemes are wide in conjunction with the GSM network coverage in addition, application is general, delay time weak point and reliability high, realize the operation of remote wireless control stepping motor by the short message mode.But these schemes need to be developed again to existing equipment, and cost is slightly high.
Summary of the invention
For defects, it is the motor remote control technology that integrates the network communications technology and control technology that the utility model aims to provide a kind of, the comprehensive functions such as remote access, control and data communication to motor device have been realized, purpose is to improve command range, reducing development cost and equipment complexity.
For achieving the above object, so the utility model proposes a kind of remote motor control system design and realization based on eCos and Web server.Adopt eCos operating system and Cortex-M3 core processor STM32F103 family chip to make up embedded web server, to realize the control to stepping motor, external memory modules adopts SRAM.
The utility model has realized that by transplanting eCos operating system serial ports, GPIO, ethernet controller, external SRAM and stepping motor etc. drive exploitation.Embedded web server can be realized automated production and network management at production field, can enhance productivity, and itself have high, the real-time and low cost and other advantages of stability.The user can carry out the operations such as operation, angular adjustment, rotating speed control by embedded TCP/IP stack LwIP and Web server to the Long-distance Control stepping motor, finally realized the functional requirement of remote motor control system.Compared with prior art, the utility model possesses the characteristics such as command range is long, real-time is better, hardware is realized comparatively simply, the overall development cost is relatively low.

Serial communication modular for the STM32F103 family chip, only need use MAX3232 the serial communication signal of TTL can be converted into the RS232 signal of standard.
Stepping motor driver module, native system select Darlington pipe driving chip ULN2003AN to drive four phase step motor, as long as the correct I/O control sequential of processor output just can be rotated by the control step motor.
The ethernet controller module, by the Ethernet interconnection network, the user uses browser input control system IP address, namely can the built-in webpage of access system, obtain respective page information.
External memory modules, native system adopt the mode of the outer SRAM of expansion sheet to increase memory capacity.
Software for Design is hardware abstraction layer HAL on hardware platform in conjunction with Fig. 3, and it is one of key of operating system transplantation, describes for operating system software layer and device drive layer provide hardware platform.Operating system can be divided into two parts, and a part is system kernel, and it is responsible for the functions such as storage administration, task scheduling, Clock management and interrupt management of whole system; Another part is system extension, mainly provides network, file system and database expanded function to the user, and this part function generally can be carried out cutting according to system's needs.On operating system, be application layer, realize the various functions of actual embedded system.
In conjunction with Fig. 4, under eCos operating system, carry out Long-distance Control by Web server, comprise motor switch setting and operational order setting.It is 3 that motor switch arranges maximum length, effectively is input as ON or OFF, and representative begins and stops respectively.It is 4 that operational order arranges length, effectively is input as R or L and adds three figure places.Such as R200, represent positive clock, the 200 expression anglecs of rotation.
