Intelligent traffic integrator

1、 Overview

The SR-XMKA-9000 series intelligent flow integrator produced by our company is developed by Bai Xing and commissioned to be manufactured by Japanese integrated circuitsA smart instrument composed of custom manufactured integrated circuits with microprocessing as its core, which integrates current automatic control systemsMost of the functions of various flow accumulation instruments in China are supplemented by a software system that draws on the strengths of others, carefully developed, and repeatedly debugged.

2、 Characteristics

The hardware of the instrument has been significantly reduced, and the composition structure of the system is relatively simple. Within the scope of user application, multiple input signals can be switched freely.pickBy using optimized design, the process has significantly improved, with no flying wires or adjusting potentiometers. All calibration and functional settings can be passedThe keyboard is composed ofSoftware completed.

Zui can set up up to four alarm outputs, with more than ten alarm methods and monitoring of alarm parameters.Two display windows, four display windows show instantaneous flow values, six display integrated values, and the actual effective integrated value is seven or nine digitsapparentDisplay the accumulated value. The P-type also has a dual reset function of external reset and internal reset, which can be viewed by setting the conversion coefficient.

3、 Function

● Input signals: standard linear signal, Pt100 thermistor, frequency signal.

● Able to square and cut off small signals. 8 compensation points and parameters.

4-digit instantaneous flow value and 6-digit or 9-digit cumulative flow value.

During frequency input, flow accumulation and instantaneous flow display can be performed on ultra-low frequencies.

● It can clear the accumulated traffic value and reset the accumulated traffic value to zero.

Programmable quantitative flow calculation, capable of batch and quantitative control.

Transmission output: 0-10mA or 4-20mA.

● Instantaneous and cumulative flow control output with adjustable values.

Two flow signals can be combined according to the ratio to display instantaneous flow and accumulate flow. The analog output can select two channels simultaneously.

Dual flow accumulation control, dual-mode analog transmission. Batch and quantitative control is possible.

After the instrument is powered off, the parameters and cumulative flow values can be saved for 200 years.

Can provide RS485 asynchronous serial communication with multiple hosts, single host, and no host modes. Communication data verification follows CRC-16 in the United States

Data communication standard, high reliability cycle, barcode verification.
