Abstract
The invention relates to a system for monitoring the motion state of a press slide. The system comprises a micro-pulse displacement sensor for measuring the displacement and the movement speed of the press slide, wherein the micro-pulse displacement sensor is connected with a field bus PROFIBUS-DP; the field bus PROFIBUS-DP is connected with a programmable controller; and the programmable controller is connected with a human-computer interface. By adoption of the structure, through a field bus technology, the amount and the investment of system hardware can be reduced, the mounting cost and the maintenance cost are reduced, and the accuracy and the reliability of measuring the displacement and the speed of the press slide are greatly improved.
Description
Technical field
The present invention relates to a kind of system, especially press ram motion state monitoring system of measuring and showing the plant equipment motion state.
Background technology
During forcing press work, the displacement of slide block and speed are most important for the duty of forcing press, and the slide block of large pressing machine is because quality is huge, and the expense of installation and maintenance is very high, its duty is difficult to monitoring and control, and the accuracy of motion state data and reliability are difficult to guarantee.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of system that can in time monitor when work displacement of large pressing machine slide block and speed.
For solving the problems of the technologies described above, press ram motion state monitoring system of the present invention, it is characterized in that: this system comprises the displacement of gaging pressure machine slide block and the micropulse displacement transducer of movement velocity, the micropulse displacement transducer connects PROFIBUS field bus-DP, PROFIBUS field bus-DP connects Programmable Logic Controller, and Programmable Logic Controller connects man-machine interface.After adopting such structure, displacement and the movement velocity of micropulse displacement sensor press ram, by PROFIBUS field bus-DP the data signal of sensor measurement is sent to Programmable Logic Controller (PLC, Siemens S7-300), PLC programs displacement and the rate signal of input is processed respectively, convert it into quantities, then show by the man-machine interface (HMI) that is connected with PLC.Use field bus technique, quantity and the investment that can save system hardware are saved mounting cost and maintenance cost, and have greatly been improved accuracy and the reliability of press ram displacement and tachometric survey.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the system block diagram of press ram motion state monitoring system of the present invention.
Fig. 2 is that the system of press ram motion state monitoring system of the present invention forms schematic diagram.
The specific embodiment
The present invention adopts displacement and the movement velocity of micropulse displacement transducer 1 gaging pressure machine slide block 2, wherein micropulse displacement transducer 1 comprises sensor measurement piece 6, the data signal of sensor 1 being measured by PROFIBUS field bus-DP3 is sent to Programmable Logic Controller 4 (PLC, Siemens S7-300), Programmable Logic Controller 4 programs displacement and the rate signal of input is processed respectively, convert it into quantities, then show by the man-machine interface 5 (HMI) that is connected with PLC.It is as follows that system forms schematic diagram:
The course of work is roughly as follows:
When press ram moves up and down, micropulse sensor 1 (model: BLT5) absolute displacement value, movement velocity and the direction of motion of detection slide block 2, then by sensor 1 inside detection signal is carried out preliminary treatment, detection signal is changed into the data signal that PROFIBUS field bus-DP3 can identify and transmit, and these deposit data within it in the buffering area of section, are waited for the reading command of bus.
Programmable Logic Controller 4 (PLC) sends reading command to bus, sensor 1 leaves the shift value in the buffering area in and just reads the internal register of Programmable Logic Controller 4 with the velocity amplitude of direction, then Programmable Logic Controller 4 programs are processed shift value and velocity amplitude respectively, change into quantities, wherein shift value is millimeter (mm), velocity amplitude is mm/second (mm/s), and adopts and represent respectively that slide block 2 moves up or down for positive and negative number.
The above only is to preferred embodiment of the present invention, is not that the present invention is done other forms of restriction, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equal variation.Every the present invention program's content that do not break away from, all drops in protection scope of the present invention any simple modification, equivalent variations and remodeling that above embodiment does according to technical spirit of the present invention.
