Abstract
The invention discloses a computer-monitored electronic belt scale comprising an electronic scale instrument, a load sensor, a speed-measuring sensor and a frequency changer, wherein the load sensor and the speed-measuring sensor are in signal connection with the electronic scale instrument, the frequency changer and the electronic scale instrument are connected by a PID (Port IDentification) controller, the regulating range of the PID controller is 4-20mA, and the electronic scale instrument and an on-site monitoring computer are in signal connection. The computer-monitored electronic belt scale is characterized in that the speed-measuring sensor is an A/D transmitter which is respectively in signal connection with the frequency changer and the electronic scale instrument, the A/D transmitter acquires speed analog signals of 0-10V from the frequency changer, and the speed analog signals are converted into speed pulse digital signals by the A/D transmitter and then transmitted to the electronic scale instrument. The invention is the computer-monitored electronic belt scale adopting the speed analog signals.
Description
Technical field
The present invention designs a kind of batching belted electronic balance, especially a kind of computer monitoring belted electronic balance that adopts the velocity simulate signal.
Background technology
At present, the rate signal of batching belted electronic balance all adopts tachogenerator.As everyone knows, the working environment of the tachogenerator of general automatic batching system is all relatively more abominable, therefore, cause the failure rate of tachogenerator high, the serviceable life of tachogenerator is very short, cause batching unstable simultaneously, measuring accuracy is had a strong impact on, and seriously hinders stabilizing and increasing of product quality.In addition, tachogenerator is changed difficulty, changes a tachogenerator and need spend long time, can influence ordinary production.Therefore, designing a kind of computer monitoring belted electronic balance that adopts the velocity simulate signal, is the present technical issues that need to address.The present invention has substituted traditional tachogenerator with the velocity simulate device, has effectively overcome the high shortcoming of traditional proportioning belted electronic balance failure rate.
Summary of the invention
Technical matters to be solved by this invention provides a kind of computer monitoring belted electronic balance that adopts the velocity simulate signal.
The technical scheme that the present invention solves its technical matters is:
A kind of computer monitoring belted electronic balance, comprise the electronic scales instrument, load sensor, tachogenerator and frequency converter, load sensor is connected with the electronic scales instrument signal with tachogenerator, between frequency converter and the electronic scales instrument by being connected by the PID controller, the range of adjustment of PID controller is 4～20mA, the electronic scales instrument is connected with the on-site supervision Computer signal, it is characterized in that: described tachogenerator is the A/D transmitter, the A/D transmitter is connected with the electronic scales instrument signal with frequency converter respectively, the A/D transmitter obtains the velocity simulate signal of 0～10V from frequency converter, becomes the velocity pulse digital data transmission through the A/D conversion and gives the electronic scales instrument.
The technical scheme that the present invention solves its technical matters can also be:
On-site supervision computing machine of the present invention can be monitored many belted electronic balances simultaneously, and the electronic scales instrument of many belted electronic balances is connected with same on-site supervision computing machine by 485 communication buses.
On-site supervision computing machine of the present invention can be monitored 18 belted electronic balances simultaneously, and 18 belted electronic balances are connected with same on-site supervision computing machine by 485 communication buses.
Compared with prior art, the present invention has the following advantages:
(1) maintenance cost and maintenance workload have been reduced, (annual in the past every belt conveyer scale need be changed 2 of speed pickups can to save 0.22 ten thousand yuan/platform year of speed pickup spare part maintenance cost every year, the speed pickup unit price is 1100 a yuan/platform, then 2 * 0.11 ten thousand yuan=0.22 ten thousand yuan);
(2) improve the equipment guarantee ability, reduce failure rate, reduce fault-time, about 4 hours of annual every comprehensive estimate, per hour 500 yuan (pressing minimum estimates), then annual every amounts to 4 * 0.05 ten thousand yuan=0.2 ten thousand yuan;
(3) improved the batching metering precision, promptly improved the proportion speed of batching, and the batching proportioning is stable, also assurance with regard to providing the foundation for the quality of sintering deposit;
(4) as from the foregoing, after transforming, the separate unit belt conveyer scale can be obtained obvious benefit more than 0.42 ten thousand yuan every year at least, if in numerous proportioning belt scales of full company, promote, and considerable benefit then.
