The beneficial effects of the utility model are that insulating data acquisition with an on-line calibration function for ship cables is realized; no tedious and complex operation is needed to be done manually; a sensor needs not to be calibrated regularly or in a hand-operated manner, and the anti-interference processing can be carried out for data; test results and analysis results can be visually displayed on the control screen of the instrument, and also can be conveniently stored in various forms based on requirements; and a plurality of measuring parameters are provided for selection, and detection for cables with different models can be realized.
Description
Technical field the utility model relates to a kind of to the online insulation data collecting instrument with calibration function of shipboard cable, belongs to electric wiring checkout equipment instrument field.
The background technology shipboard cable is the carrier of signal transmission and power transfer between the electromechanical equipment; Its laid condition is comparatively complicated; Situation such as environment greasy dirt, salt solution, electromagnetic radiation, irradiation are comparatively serious; And the security of operation of cable is related to the overall operation security of boats and ships, and can the quality of insulating property be directly connected to equipment and normally move, and therefore is necessary the cable in using is carried out the insulation parameter collection.
The detection of insulation parameter at present mainly comprises the core temperature, electric current, and Leakage Current, humidity etc., the main equipment that adopts is core with the single-chip microcomputer, the collocation different sensor is carried out the related data collection.But the accuracy of the stability of this system and image data is difficult to be guaranteed; Antijamming capability and shock resistance in the operational process are relatively poor; And the inventory analysis ability of data is relatively poor, need in some cycles, change or clear up storage medium, has therefore lost Significance of monitoring.Above-mentioned shortcoming has shown the security and the stability that need take into full account its operation for this measuring method; Traditional insulation resistance detection method can't satisfy the requirement of present stage detection task; Need to adopt more stable cable design; Increase the storage space Treatment Analysis of line data of going forward side by side, and adopt internal sensor to carry out calibration and the analysis-by-synthesis function of measured value, the disturbing factor of eliminating in measuring process; Design shockproof anti-interference structure, the robotization and the intellectuality of highly integrated realization cable insulation parameter acquisition.
The defective that summary of the invention exists in view of prior art; The purpose of the utility model provides a kind of to the online insulation data collecting instrument with calibration function of shipboard cable; When the safe temperature of realization system is moved, guarantee the real-time collection and the real-time analysis function of data, regularly auto-calibrating sensor; The standard image data is also carried out anti-interference process, sets up jumbo measured database for cable more quickly.
For realizing above-mentioned purpose, the technical solution that the utility model adopted mainly is: a kind of to the online insulation data collecting instrument with calibration function of shipboard cable, it comprises central control chip, human-computer interaction module, data acquisition unit and data-carrier store; It is characterized in that: the C8051F340 chip that sensor is arranged in said central processing element adopts and has; Described human-computer interaction module comprises touch display screen and supervisory keyboard; Described data acquisition unit comprises clock module, A/D conversion module, display module, immunity module, automatic calibration module, power module, alarm module; Described data-carrier store is made up of large-capacity storage media USB flash disk, memory module, DAP.
A kind ofly be: realized to the online insulation data acquisition of shipboard cable with calibration function to the online beneficial effect of shipboard cable with insulation data collecting instrument of calibration function; Need not artificial carry out the work of very complicated; Regularly perhaps manually carry out the calibration of sensor; Data are carried out anti-interference process, and test result and analysis result can not only be presented on the instrument control flow intuitively, but also can save as various ways as requested easily; Have multiple measurement parameter and select, can realize detection the different model cable.

Described A/D change-over circuit is that input signal changes; High-precision 10 bit pads and Acquisition Circuit guarantee the input of analog quantity and the accuracy of conversion; Amplify in proportion or dwindle signal through discharge circuit, be transformed to the working range that central processing unit can allow.
Said memory module selects rational data layout to select through reception and storage that the data processing chip CH375 of specialty accomplishes data simultaneously.
Described human-computer interaction module, the operator can carry out the observation and the analysis of data through display screen, and the input through keyboard simultaneously realizes the parameter setting to main frame measurement pattern and memory module.
Described immunity module reduces extraneous electromagnetic interference (EMI) and the vibration effect of shielding in gatherer process through consequence devised, through the analysis of software program, gets rid of the information of interference of receiving.
Described automatic calibration module is through the sensor of chip internal and the signal that sends certainly, analyzes the error that the signal value that obtains is judged data in gatherer process, revises the parameter of in house software automatically, accomplishes the automatic calibration of data.
Embodiment 2:
Automatically calibration process, the opening power button, treat system initialization accomplish stable after; Press outside automatic calibration knob, the bright state of red led will appear in system, say the printed words of demonstration " system calibrates automatically; just a moment,please " on the interface, bear with 1 minute at this, can accomplish automated calibration system institute connection sensor; Red led will extinguish this moment, show that calibration procedure accomplishes automatically, carry out the normal gatherer process of data.
Embodiment 3:
The collecting work process flow diagram of Fig. 2 the utility model at first calls the initialization function after system powers on, single-chip microcomputer itself and each peripheral module are carried out initialization operation; After treating that initialization is accomplished, program just gets into major cycle, mainly contains 3 functional program modules in the major cycle; Display module, key-press module, clock module; These 3 functions constantly are recycled recall in major cycle, realize functions such as systemic-function collection, storage, demonstration.After pressing calibration knob, system will get into interrupt routine, carry out automatic calibration module, accomplish the collecting work that continued is carried out data.
