1.fuel shut off solenoid valve
Censtar solenoid fuel valve show host to communication with other tankers, fuel shut off solenoid valve or not to consider this command;Conversely, if the end of the refueling operation, will respond to this command, the charging information sent to the host, olenoid valves to wait for the host postback/charge zero information.
Solenoid valves communication system using VB6. 0, control to realize the serial communication, the initialization is set to / 9, 600, 0, 8, 10, the fuel shut off solenoid valve is: the baud rate for 9, 600 b/s and odd parity, 8 data bits, stop bit.After the project form embedded communication MSComm control, in order to use this control to control a serial port communication operation, have to insert the control in the application.For application of a dialog box for this insert solenoid fuel valve control.
2. hydraulic solenoid valve
Gas solenoid valve control called MSComm1, oil solenoid valve and to add the two timer control timperiodic and timnonperiodic and a command button control CmdNonPeriodic. Communication control is used to access a serial port to send and receive data,;Cycle timer control hydraulic solenoid valve is used to control every 500ms from the computer to send periodic commands all data points
Censtar gas solenoid valve command button control with the cycle timer control (timnonperiodic) for sending aperiodic command.MicroMaster tankers echo the status information of a frame to 14 bytes.The event driven communication mode oil solenoid valve is used on programming, serial port for every 14 characters and activate a event, the message processing function with the corresponding processing code, used to read status word ZSW and HIW each state parameter, hydraulic solenoid valve and make corresponding processing, such as display, etc.
3. oil solenoid valves
Sensor plate double photoelectric board: solenoid valve the amount of oil meter is converted into electrical signal into a computer. Switch solenoid valve suppliers : oil solenoid valves control tanker start.Tanker motherboard: external signal input processing operations, and control of external circuit, and data exchange with IC card board.
Censtar is a solenoid valve suppliers to provide solenoid valve responsible for communication and interior management system.IC card board: the IC card information processing and computing.Provide the safety of the IC card operation control.Keep communication of tankers motherboard.The IC card tanker system structure in the xinjiang military region within the scope of IC card automatic refueling tankers is established and computer network management system, oil solenoid valves make the military oil work with job automation, clearing electronic, the direction of the management network, decision-making information to major historic change.Significantly improve the working efficiency, greatly strengthen the management and control ability of oil supplies.
4. fluid solenoid valve
Fuel solenoid valves is based on industrial control computer, fluid solenoid valve based on non cassette tankers electronic, after equipped with IC control circuit part and component.Has the function of card machine linkage only solenoid valve china insert the correct IC card can normal refueling.So-called IC card.
Censtar fuel solenoid valves's appearance is like credit card, but the card contains one or more in conformity with the relevant standards of the international standardization organization (ISO) integrated circuit (IC) chip and package to facilitate the people carrying the CARDS, it has a temporary or permanent data storage capacity, which is a self protection can be memory. In fact fluid solenoid valve is the integrated circuit card IC card, solenoid valve china is a kind of along with the development of semiconductor technology and application security requirements such as increasing arises at the historic moment, is a capacity for microprocessor and large capacity storage of integrated circuit chips embedded in the plastic substrate and made of card.
5. solenoid gas valve
In double solenoid valve periodic verification process, solenoid gas valve especially under the condition of the environment temperature is higher or lower, to monitor the environment temperature (5 ℃) and oil and the environment temperature natural gas solenoid valve is less than 10 ℃ (over to the metal heat preservation measures) again.
Censtar double solenoid valve is carefully measure temperature and oil gun metal oil temperature gauge, to avoid mistake in temperature measurement, solenoid gas valve is concluded that error of the tanker was carried out on the tanker of error of error adjustment, so that the oil operators and consumers interests suffered unnecessary loss.How to correct, accurate measurement temperature?Ambient temperature must be near the natural gas solenoid valve tankers no metal gauge measurement, temperature and oil gun metal gauge oil temperature measurement method.
6. solenoid operated valve
General technical requirements include: pneumatic solenoid valve appearance, small solenoid valve flow measurement transducer, encoder, JiKong motherboard, indicating device, oil and gas separator, hose, explosion-proof performance, environmental conditions, the emc performance, additional requirements, with functions of tax-controlled tanker tankers work stability, solenoid operated valve adaptability of tankers transport packaging requirements.
Solenoid valve is a tanker switch valve in the hydraulic system, pneumatic solenoid valve consists of large and small two valves, separately controlled by tankers computer device, the application of it to improve the accuracy of quantitative refueling tankers.
Counting sensor is tankers flowmeter turning parts of mechanical signal into pulse signal, using encoder in anti-cheating tankers.
Computer device is the control of the tanker, operation, small solenoid valve display and data storage center, it get tankers by oil gun switch boot signal, again through the motor, solenoid valve start refueling tanker, solenoid operated valve through the pulse counting signal counting sensor, count on through the flow meter of oil.
