TEKNIGIN BILINEN DURUMU Oransal PQ valfi: sistemdeki (hidrolik ile çalisan makinalarda); basinç ve debiyi giris sinyali ile orantili olarak kontrol eden bir valftir. Mevcut Oransal PQ Valfin kontrolünü saglayan elektronik kartlar; valfi kontrol etmek için PLC' ye DAC (Sayisal degeri analog degere dönüstüren elektronik devre) baglanmaktadir. PLC 'den voltaja dönüstürülmesi için örnegin; 0-4000 arasi sayi degeri DAC' a (Digital to Analog Converter) verilir. DAC verilen bu sayi degerini 0-10 voltluk elektrik sinyaline dönüstürür. Dönüstürülen bu sinyal PQ Valfin kontrolünü saglayan elektronik karta verilir. Bu kart 0-10 voltluk elektrik sinyalini PWM (Pulse Width Modulation) yöntemiyle örnegin; 0-24 (kart beslemesi 24 volt ise) volta dönüstürtülür. Elde edilen 0-24 volt ile Oransal PQ Valfin debi ve basinç degerleri 0 - Maksimum arasinda degisim gösterir.

TR TR TR TR TR TR DESCRIPTION MICROPROCESSOR PQ PROPORTIONAL HYDRAULIC VALVE CONTROL CIRCUIT CARD TECHNICAL FIELD This invention is related to the microprocessor PQ proportional hydraulic valve control circuit to be used in the machinery industry. KNOWN STATE OF THE ART Proportional PQ valve: in the system (in hydraulically operated machines); It is a valve that controls pressure and flow in proportion to the input signal. Electronic cards that control the existing Proportional PQ Valve; To control the valve, DAC (electronic circuit that converts digital value to analog value) is connected to PLC. For example, to convert from PLC to voltage; The number value between 0-4000 is given to DAC (Digital to Analog Converter). DAC converts this given number value into a 0-10 volt electrical signal. This converted signal is given to the electronic card that controls the PQ Valve. This card transmits the 0-10 volt electrical signal with the PWM (Pulse Width Modulation) method, for example; 0-24 (if the card supply is 24 volts) is converted to volts. With the resulting 0-24 volts, the flow rate and pressure values of the Proportional PQ Valve vary between 0 - Maximum. The speed of the hydraulic cylinder used in the machine changes due to flow rate and its force changes due to pressure. Figure.1 Disadvantages of controlling Proportional PQ valve with DAC added to PLC; 1. With the current method, a DAC is needed to obtain the PWM (Pulse Width Modulation) signal used in the system. For this reason, it is costly for companies. 2. It does not provide flexibility of use in controlling the proportional PQ valve. 3. With this method; Proportional PQ does not use microprocessors to control the valve, instead electronic materials called OPAMPs are used. Since OPAMP is not a microprocessor, it cannot be programmed and is not suitable for software development. DESCRIPTION OF THE INVENTION The invention in question eliminates the disadvantages and meets the needs described in the state of the art. The invention in question is related to the microprocessor PQ proportional hydraulic valve control circuit to be used in the machinery industry. The advantages obtained with the invention in question are; - There is no need to use the DAC (Digital Analog Converter) module added to the PLC. However, it is suitable for use with DAC when desired. - The electronic card to control the proportional PQ valve is made with a microprocessor. - In the new invention, the data coming to the microprocessor using 4 different methods is analyzed in accordance with the program and produces a PWM signal to control the PQ valve. - It can be developed by changing the software or adding to the hardware.
