Embodiment 1

[0023] Embodiment 1, with reference to figure 1 , a workshop equipment monitoring system based on Powerlink, which is mainly composed of an upper computer monitoring PC, a Powerlink master station and a lower computer data acquisition slave station (referred to as a Powerlink slave station or a slave station); a Powerlink master station and each lower computer data acquisition slave station The Powerlink bus is used to communicate between them; the Powerlink master station issues start instructions to each slave data acquisition station of the lower computer, and processes the recorded workshop equipment voltage, current, temperature, speed, vibration, pressure, sensor displacement, and switch transmitted on the Powerlink bus in real time. Quantity, workshop environment variables and power quality operating parameters, monitor the real-time operation status of workshop equipment, all data is stored on the server, and realize automatic equipment failure alarm and control the act...

Embodiment 2

[0024] Embodiment 2, with reference to figure 2 , a kind of workshop equipment monitoring system based on Powerlink described in embodiment 1, the controller of the Powerlink master station uses the minimum system of STM32F407ZGT6 single-chip microcomputer as the core component, and the minimum system of STM32F407ZGT6 single-chip microcomputer is connected with onboard buttons, LCD, and 4 switches Input, 4-way switch output, 4-way analog input, 2-way analog output, JTAG debugging interface; 4-way analog input is used as the input port for temperature and pressure acquisition, and 8-way switch value input and output are used as I / O equipment group Communication port for control signals.

[0025] The workshop equipment monitoring system mainly completes the data acquisition task of the state variables in the workshop equipment operation process. Specifically include: motor voltage and current, equipment temperature, motor speed, vibration frequency, etc., as well as some statu...

Embodiment 3

[0027] Embodiment 3, in a kind of Powerlink-based workshop equipment monitoring system described in Embodiment 1 or 2: the Powerlink protocol stack transplantation of the Powerlink master station controller and the lower computer data acquisition slave station controller: the transplantation of Powerlink is divided into master station The protocol stacks of the controller and the slave station controller are transplanted separately, mainly including: the modification of the network card driver, the configuration of the object dictionary, and the configuration of the timer part; the network data of the master station is triggered by a high-precision clock, and the timing is carried out with the slave station. Data interaction and execution of IO operations; Powerlink master-slave stations directly use the form of master station polling slave stations to transmit real-time synchronous data, and transmit non-real-time ordinary data in the latter part of a cycle; Powerlink communica...

Abstract

The invention discloses a workshop equipment monitoring system based on Powerlink. The system mainly comprises an upper computer monitoring PC, a Powerlink main station and lower computer data collecting sub-stations; the main station is in communication with each lower computer data collecting sub-station through a Powerlink bus; the main station sends enabled instructions to each lower computerdata collecting sub-station, processes running parameters which are transmitted in the Powerlink buses and used for recording the voltage, current, temperature, rotation speed, vibration, pressure, transducer displacement, switching value, workshop environmental variables and power quality of workshop equipment in real time, and monitors the real-time running state of the workshop equipment; all data is stored in a server, and the functions of achieving full-automatic failure warning and controlling an execution mechanism to timely switch on and switch off the equipment can be achieved; according to the workshop equipment monitoring system, a Powerlink real-time industrial Ethernet protocol is transplanted to an ARM platform, jitter is controlled to be l us according to the switching valueof the monitoring system based on the Powerlink, the communication period reaches 200 us, and therefore definite and real-time communication monitoring of the workshop equipment is achieved.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a Powerlink-based workshop equipment monitoring system. Background technique [0002] Workshop equipment operation status monitoring is to collect and analyze data from the sensors installed on each station of the operation equipment, make an alarm for workshop equipment failures based on the analysis results, and control the execution structure to adjust and control the equipment to reduce the occurrence of equipment failures probability, provide a basis for equipment condition maintenance, and ensure the stable operation of equipment. With the development of communication technology, the status monitoring of workshop equipment requires real-time and deterministic data transmission. [0003] At present, the upper layer of the workshop equipment control system generally adopts the Ethernet communication method, and the lower layer generally adopts the field bus communication method, which ...
