The difference between electronic counting and photoelectric counting machine

The first generation of electronic counting machine:

It is a small electronic counting machine, the volume is only the size of a desktop computer, more can be said to be an electronic instrument, mainly used photoelectric sensor principle of particle counting, used in small moving objects, because of its high speed, non-contact measurement of object falling position requirements etc. they have been widely used in agricultural seed counting instrument.

The second generation of photoelectric counting machine:

Until the last century by the end of 70s was officially used in the pharmaceutical industry, we call the first generation of photoelectric counting machine. Perhaps, I love the automatic electronic counting machine, why? Because it is on the basis of the original number of seeds of research and development and innovation, the real meaning is the rapid leap in the number of particles. Is the real solution to the labor force, reduce the use of costs, but also fully realize the pharmaceutical industry outsourcing machinery packaging equipment fully automated.

At that time, the technology work principle: the initial adjustment of vibration feeding plate, the hopper grain along the track vibration plate continuous forward vibration, from the front of the channel until the photoelectric detection falls and touch photoelectric sensor to start work, counting, when the particle reaches a predetermined number, from PLC to the electrical outlet valve closed signal, the number of good grain fall in exports on the bottle, to achieve the number of particle counting function, (at present, many of the domestic manufacturers are basically counting machine is to use this form to complete), the mechanical part is to control the servo motor and cylinder). In this way, the use of the pharmaceutical industry is the most popular.

Disadvantages: this method is not accurate in terms of particle size, error rate, and speed. Because the use of PLC single machine, the use of serial execution instructions, speed is not fast, and infrared pulse single line scanning. To realize the true meaning of the photoelectric counting machine is implemented, because nearly several times in recent years, labor costs rise, counting machine log pharmaceutical factory again put forward higher requirements, and the two key points: counting the speed faster, the accuracy is higher.

The third generation of photovoltaic (3D) counting machine

With the application of customer requirements to promote, in 2009 the real meaning of the photoelectric counting machine was used so far, is the customer satisfaction and the application of the best counting machine, then, the difference between photovoltaic (3D) photoelectric counting and the first generation counting machine before the first generation ?

A: the software system for counting the number of particles should be changed into FPGA, and it is also the most popular software system for aeronautical technology. The most advanced is the anti radiation, high performance and low power consumption. FPGA can be reconstructed by software programming structure and working mode of the hardware, modify the software program is equivalent to changing the hardware, fast speed, high reliability. Practice has proved that FPGA software system has the following advantages:

1.It can realize parallel work on hardware, and has a bright future in real-time measurement and control and high-speed applications;

2.FPGA device is implemented in software, but the physical mechanism is as reliable as that of a pure hardware circuit

3.FPGA high reliability, just overcome the current other manufacturers use MCU appear run fly congenitally deficient phenomenon, a few grain precision is not high problem. And the use of PLC single machine, the use of serial execution instructions, speed is not fast features. Taiwan well-known manufacturers to introduce mature high-speed electronic chip technology, based on FPGA high-speed microprocessor technology, with Chinese dynamic graphics display operating system, parameters can be set up or adjusted.

4. Automatic fault diagnosis and real-time monitoring alarm display system, and can store more than one group of parameters, the product can be called directly.

B: 3D infrared scanning counting machine is single infrared pulse to change the pulse to form a net shape of the grains were dead without scanning log.
