Description
Technical field
The application belongs to coal apparatus field, specifically, more particularly to a kind of coal mechanical equipment stream monitoring system.
Background technique
The division of coal sample is that marketable coal gathers and processes the important ring during sample, and the division of mechanization coal sampling and preparing equipment
Device is exactly the important component for realizing division in the online sample making course of coal sample, the core of division process be will to one section of coal sample into
The uniform division of row, whether science decides whether institute's coal sampling is representative to division process.Current coal mechanical equipment one
As be equipped with host computer, can realize the signal monitoring that work equipment by configuration interface.But this signal monitoring can only
Monitor whether mechanical organ acts, and for reduction device, it is desirable to monitor its specific working condition.
For this problem, present mechanical equipment designs and manufactures producer all in the installation monitoring of the movement position of reduction device
Camera is observed the process of division by display, has substantially carried out the real time monitoring of division, and can return if necessary
Video recording is put to be traced.
Although above-mentioned apparatus solves the monitoring problem of division process to a certain extent, due to video monitoring itself
Limitation, as: since memory space limits, video record be cannot keep within retest date；It can only be to the single of reduction device
Movement is observed, and macroscopical can not check the process analysis procedure analysis of coal sampling by the gross；Cope with the adverse circumstances such as coal dust not in special circumstances
And it waits.The utility model devises the new stream monitoring system of one kind and can also be installed on the system for solving this problem
Primary sampler and other reduction devices at different levels.It is therefore desirable to propose a kind of coal mechanical equipment stream monitoring system.
Summary of the invention
A kind of coal machine for being monitored to the coal stream after reduction device division of being designed to provide of the application is adopted and is set
Stock stream monitoring system can be realized and carry out more efficient monitoring to the coal stream mode after the completion of division to judge reduction device
Working condition, and monitoring data are stored without larger space.
In order to achieve the above objectives, the application is achieved through the following technical solutions:
Coal mechanical equipment stream described herein monitors system, including ultrasonic distance measuring module, PLC execute mould
Block, monitoring module and display module, wherein the ultrasonic distance measuring module is using ultrasonic distance-measuring sensor to flowing through it
The detection of relative distance between the coal stream of installation site；The PLC execution module is for connecing ultrasonic distance measuring module
The signal of receipts is handled, and signal is fed back to monitoring module；The monitoring module is used to store PLC execution module feedback
Signal；The display module is used to show the Dynamic Signal of PLC feedback and the signal of monitoring module storage.
Further speaking, PLC execution module described herein is connect by A/D conversion module with monitoring module.
Further speaking, ultrasonic distance measuring module HC-SR04 ultrasonic distance-measuring sensor described herein.
Further speaking, PLC execution module described herein is serial using the S7-300 of SIMMENS company.
Compared with prior art, the beneficial effect of the application is:
1, the application is monitored using ultrasonic distance-measuring sensor to by the coal stream of reduction device, passes through coal
The variation of distance is between stream and ultrasonic distance-measuring sensor come the case where judging the coal stream by division.
2, the monitoring result in the application is stored in the form of monitoring figure line, because its occupied memory is smaller,
The defect that video can be overcome to store stores date longer monitoring record.
Detailed description of the invention
Fig. 1 is the functional block diagram of the application.
Specific embodiment
Technical solution described herein is described further with reference to the accompanying drawings and embodiments.
Embodiment 1: a kind of coal mechanical equipment stream monitors system, including ultrasonic distance measuring module, PLC execution module,
Monitoring module and display module, wherein the ultrasonic distance measuring module is using ultrasonic distance-measuring sensor to flowing through its installation
The detection of relative distance between the coal stream of position；The PLC execution module is used for received to ultrasonic distance measuring module
Signal is handled, and signal is fed back to monitoring module；The monitoring module is used to store the letter of PLC execution module feedback
Number；The display module is used to show the Dynamic Signal of PLC feedback and the signal of monitoring module storage.The PLC execution module
It is connect by A/D conversion module with monitoring module.The ultrasonic distance measuring module uses HC-SR04 ultrasonic distance-measuring sensor,
It is capable of providing that 2cm ~ ~ 400cm is contactless apart from inducing function, and range accuracy can achieve 3mm.The PLC executes mould
Block is serial using the S7-300 of SIMMENS company.
The application is problem to solve is that supervise the coal stream mode in coal transmission process after reduction device
The memory space that the data surveyed, and obtained occupy is smaller, so as to store more data.
In this application, the ultrasonic distance measuring module uses ultrasonic sensor, is installed on where reduction device
Downstream at the stream flowing of belt feeder or elephant trunk is specifically installed on the sealing cover for the belt conveyer to be monitored,
The direction of the launch is against coal stream, and if having the conveying of coal stream on belt conveyor, ultrasonic distance-measuring sensor issues super to coal stream
Sound wave, ultrasonic distance-measuring sensor can detect its distance relative to coal stream, and this distance is real-time change,
The signal detected can be transmitted in PLC controller by the cable being attached thereto.PLC controller employed in the application
Using the S7-300 series of SIMMENS company, standard CPU314, built-in 1 RS485 bus communication interface, power supply mould are used
Block selects PS307, rated current 2A；Expansion I/O module (digital quantity input/output module) selects SM323, built-in 8 railway digital
Amount input, the output of 8 railway digital amounts etc..
It, can be by above-mentioned electric current after PLC controller receives 40 ~ 20mA signal from ultrasonic distance-measuring sensor
Signal is transferred to display module and carries out dynamic display in real time, and can will be transferred to after signal processing by A/D conversion circuit
Monitoring module is stored.And in this application, the display module using have touch control display screen,
Stored data and display real time data can be called on the touchscreen.
In this application, PLC execution module, monitoring module and the display module, between each other using
Ethernet interface can be realized the high-speed transfer and data sharing of data.
