Problems solved by technology

As we all know, the working environment of the speed sensor of the general automatic batching system is relatively harsh. Therefore, the failure rate of the speed sensor is extremely high, the service life of the speed sensor is very short, and the batching is unstable, and the measurement accuracy is seriously affected. Stability and improvement of product quality
In addition, it is difficult to replace the speed sensor, and it takes a long time to replace the speed sensor once, which will affect the normal production

Embodiment Construction

[0016] As shown in the figure, a computer monitors an electronic belt scale, including an electronic scale instrument, a load sensor, a speed sensor and a frequency converter. The load sensor and the speed sensor are connected to the signal of the electronic scale instrument. The controller is connected, the adjustment range of the PID controller is 4~20mA, the electronic scale instrument is connected with the on-site monitoring computer signal, it is characterized in that: the described speed sensor is an A / D transmitter, and the A / D transmitter is connected with the The frequency converter is connected to the signal of the electronic scale instrument, and the A / D transmitter obtains the speed analog signal of 0-10V from the frequency converter, converts it into a speed pulse digital signal through A / D conversion and transmits it to the electronic scale instrument.

[0017] One on-site monitoring computer can monitor multiple electronic belt scales at the same time, and the el...

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 [0001] The invention designs an electronic belt scale for batching ingredients, in particular a computer-monitored electronic belt scale adopting speed analog signals. Background technique [0002] At present, the speed signal of the batching electronic belt scale adopts the speed sensor. As we all know, the working environment of the speed sensor of the general automatic batching system is relatively harsh. Therefore, the failure rate of the speed sensor is extremely high, the service life of the speed sensor is very short, and the batching is unstable, and the measurement accuracy is seriously affected. Stability and improvement of product quality. In addition, it is difficult to replace the speed sensor, and it takes a long time to replace the speed sensor once, which will affect normal production. Therefore, it is a technical problem to be solved at present to design a computer-monitored electronic belt scale that adopts the speed analog signal. The in...
