2 The characteristics and functions of this system (1) Using intelligent, modular, standardized, networked combination of structures, temperature, process signals, frequency and other functional units in any combination. The PC host is used as the core, and LANs are formed according to the functional requirements. That is, the independent functions of each smart unit are maintained, and the software function can be used to compose the check network to complete the automatic calibration and detection of the school instruments in the laboratory.
(2) The system controls the unit components through the PC host, which can realize the check and automatic data collection of the automatic balance recorder and the regulator. Through the information transmission between the instrument and the system, no manual data copying is needed to realize paperlessness. Calibration to ensure the accuracy and reliability of the calibration test.
(3) The verification system retains the function of manual independent verification. It can independently use the smart units from the computer, manually complete the verification work, meet the calibration requirements of any instrument, and can also avoid the sudden unexpected factors Verification of instrumentation.
3 Parameters of the various components of the system and their applications (1) Thermocouple unit specifications: thermocouple simulation output, thermocouple measurement. It can be applied to the calibration instruments such as S, K, E type and other input models such as automatic balance recorder and digital display temperature controller. The accuracy is less than ±1°C and the resolution is ±0.1°C. Compensation methods are internal compensation, external compensation, and designated compensation.
(2) Technical specifications of the thermal resistance unit: thermal resistance simulation output, thermal resistance measurement. It can be applied to the calibration instruments such as Pt10, Pt100, cu50, cu100 and other input models such as automatic balance recorders and digital display temperature controllers. Accuracy is less than ±1°C, with a resolution of ±0.1°C. (3) High-precision digital multimeter (Equipped with KEI'THLEY2000, 6-digit display) Technical index: Temperature instrument for measuring standard voltage input, standard current input meter. Standard voltage measurement range (-100mV ~ +100mV, -50mV ~ +50mV, -5V ~ +5V). Accuracy is 0.01% FS (4) Frequency meter Specifications: The output waveform is square wave, triangle wave, sine wave, available In the automatic balance recorder operation, aging test. Output range (0.1Hz~1MHz), accuracy 0.005% FS4PC host computer and serial connection of each unit's serial port PC host's built-in serial port conversion card (as an eight-RS232 serial conversion card), the RS232 conversion port and the card The unit is connected so that the host can communicate with the units. (The components are all RS232 interfaces.) No jumpers are required to connect the interfaces. Connect according to the serial port standard.
4 software presets of the automatic inspection and measurement system 4.1 The functions implemented by the software (1) The automatic analog output, automatic data acquisition, processing, storage, automatic generation of verification result files, and printing of standard certificates are realized by controlling the various component units through a computer. report.
(2) The software of the automatic inspection and determination system is based on the corresponding national inspection and measurement procedures and is based on the relevant standards of IS09000. The system used is Chinese Windows98. It has a friendly operation interface and the inspection and measurement operations are simple and convenient.
(3) The software has a database that manages instrument data of the entire enterprise being schooled, so that all instruments to be inspected will be withdrawn from the purchase of the original data file records, each time the check calibration, maintenance records until the end of the instrument and instrument retirement, All the files can be created. The user can query by instrument name, model, manufacturer, adjustment date, and use department, which breaks the traditional measurement management concept. If it is connected to the company intranet, it can also make the inspection and measurement work in this room step into the information and network era of computer management.
4.2 The main program block diagram of the software This software uses VisualBasic6.0 programming under Windows98 platform, full Chinese interface, standard Windows operation, convenient and quick.
4.3 The preparation of the software program code This software uses the communication control MSCOMM of VB6.0 to realize the communication between the computer and each component unit, and conforms to the serial communication standard. Use a serial port to communicate with a computer, write a VB program to access the serial port, and read the displayed data. The output of the system component unit is the RS-2320 standard interface. The baud rate is 9600, even parity, 7 data bits, and 2 stop bits. All characters send 11 ASCTI codes, one start bit. The communication with serial port in VB needs to introduce control MSCOMM serial communication control (in MicrosoftCommControl6.0). The above code realizes the communication between the entire inspection and measurement system, and the software can realize various instruments and meter verification data through the perfect code. Automatically collect, process, and automatically generate check data tables, reports, and certificates.
5 Conclusion The use of automatic inspection and measurement system can not only shorten the inspection and measurement time, reduce the labor intensity of personnel, but also realize the automation of inspection and measurement of raw data processing, avoiding the factors of manual operation error-prone and increase the efficiency of inspection and measurement work ten times. the above.
Self-propelled barges may be used as such when traveling downstream or upstream in placid waters; they are operated as an unpowered Barge, with the assistance of a tugboat, when traveling upstream in faster waters. Canal barges are usually made for the particular canal in which they will operate.Self-propelled barges are useful for inland waterways transport in placid waters. They can also be used with a tug where needed and are useful for lighterage, ferrying, and transport of cargo and construction materials. Our vessel charter team are happy to advise on the right vessel for your needs.

What is the specifications of our propelled barge
A. General
High accuracy and fully welded, sealed, painted construction can be used for marine engineering of submerged and floating lines in pontoon or dock area or working platform.
B. Construction
The construction is to be built according to the drawing with rules of good workmanship and to be built the longitudinal frame system.
All penetrations of longitudinal through transverse bulkhead are closed with slot plate or stiffeners are interrupted at bulkhead and continuity is realized with brackets, to ensure to avoid any abrupt changes in strength structures.
Subdivided into some watertight compartments, and tanks are pressure tested after completion of all welding but before painting, testing pressure normally 2.35 mwg or 0.2 Bar.
C. Materials
All fabricated steelwork used in the construction of the pontoon will be to manufacturing standard of UniSite or other classification society.
All steel used to be blasted and shop primed both sides.
All materials proposed will be selected to comply with the latest Health and Safety Rules.
Paint systems for hull protection will be of the highest quality (Hempel, Inter, Sigma, Jotun)
D. Welding
All welding will be performed in accordance with drawing and order and UniSite experience and all welding will be continuous.
E. Workmanship
The workmanship on the hull and fittings throughout have good marine practice. Care are taken to ensure fair lines, smooth surfaces and neat welding. All materials and equipment installed in, or delivered with the pontoon will be new and of good marine quality.
