Description
Technical field
The utility model relates to a kind of data memory protection technology, particularly a kind of SD card data-carrier store peculiar to vessel.
Background technology
Integrated digital formula protective device needs a large amount of data, comprising: the systematic parameter of device, Protection parameters, collection capacity calibration parameter, fault waveform, fault alarm record etc.At complex protection device, power on, call during the action of operation, alarm and protection relevant parameter information; wherein many important parameters are because complex protection device installation site is different, different, the external first and second loop sample devicess of object of protection are different and variant; at deliver the vessel in earlier stage, the commissioning staff of manufacturer has carried out parameter configuration and has preserved according to test and actual conditions.
At present, integrated digital formula protective device both domestic and external uses built-in hard disk, built-in data chip storage data mostly, or is uploaded onto the server and stored by bus network.When plant failure, repair and maintenance, HardwareUpgring, need to or carry out correlation test by the data derivation in device and reconfigure parameter, increased so in large quantities servicing time, also may cause fault because of parameter configuration error; And most of boats and ships do not possess the condition of build-in services device, complex protection device cannot be articulated on server.
Summary of the invention
The utility model is the problem for the preservation of marine protection device data and the inapplicable Internet Transmission of parameter change; a kind of SD card data-carrier store peculiar to vessel has been proposed; use the parameter information of SD card storage complex protection device; coordinate hardware safety to design the destruction that anti-locking apparatus is invaded by forceful electric power simultaneously; coordinate software fault-tolerant to process, efficiently solve above-mentioned deficiency.
The technical solution of the utility model is: a kind of SD card data-carrier store peculiar to vessel, be contained on metal electric device of air, SD draw-in groove mouth is left at electric device rear, corresponding SD draw-in groove mouth is installed SD mount pad, SD draw-in groove is installed on SD mount pad, a SD card radome has been installed at SD mount pad rear, SD card inserts in SD draw-in groove, SD draw-in groove mouth place is by conductive gasket, SD card cover screw sealing pressing, guarantee the conduction continuity of SD card data-carrier store and metal electric device of air, SD card drives loop to having insulating power supply and data bus isolation between SD card.
Described SD card data-carrier store extension line adopts multicore shielding line.
Described data bus isolation adopts light-coupled isolation.
The beneficial effects of the utility model are: the utility model SD card peculiar to vessel data-carrier store, and when changing, upgrading at device, only former SD card need be taken out and put into new equipment, can come into operation immediately; At the inner any unit failure of device and even short trouble, all can not damage data in SD.Meanwhile, the utility model does not limit to and is applied on digital complex protection device, can be applicable to boats and ships with needing on the electric device of data storage.
Accompanying drawing explanation
Fig. 1 is the utility model SD card peculiar to vessel data-carrier store hardware safety theory diagram;
Fig. 2 is the utility model SD card peculiar to vessel data memory structure schematic diagram;
Fig. 3 is the utility model SD card data-carrier store peculiar to vessel front scheme of installation.
Embodiment
In order effectively to guarantee the data security of SD card, SD card data-carrier store hardware safety theory diagram peculiar to vessel as shown in Figure 1, in electric device, SD card drives loop to increase insulating power supplies 2 and data bus isolation 1 to SD card 3.Boats and ships use, construction environment is poor, personnel's maloperation or insulation exceptionally may cause forceful electric power to invade equipment, outside the use of insulating power supply guarantees that forceful electric power is effectively isolated in, the damage of inner other plate of Bus Photoelectric isolation assurance device does not all affect SD card, thereby the data security that guarantees SD card, this SD card data-carrier store peculiar to vessel is configurable on any metal electric device of air peculiar to vessel.
SD card data memory structure schematic diagram peculiar to vessel as shown in Figure 2, in order to facilitate the plug of SD card, the utility model SD card slot is arranged on metal electric device of air rear, SD draw-in groove mouth is left at electric device rear, as shown in Figure 3, corresponding SD draw-in groove mouth is installed SD mount pad 8, and SD draw-in groove 4 is installed on SD mount pad 8.SD draw-in groove mouth place is by conductive gasket 6, the 7 sealing pressings of SD card cover plate, to guarantee the conduction continuity of SD card data-carrier store and metal electric device of air.In order to prevent the interference of center line road, rear cabin to SD card, a SD card radome 5 has been installed at SD mount pad 8 rears, adopt multicore shielding line as the connecting line of SD card and master control borad, good shielding and protection have been accomplished, Fig. 3 is SD card data-carrier store peculiar to vessel front scheme of installation, is the right view of Fig. 2 when SD card cover plate 7 is not installed.SD card data-carrier store extension line adopts multicore shielding line, introduces in the master control board of electric device, has accomplished good shielding and protection.
SD storage area is divided, and partitioned storage parameter, wherein comprises altogether: the parameter of dispatching from the factory, actual parameter, actual parameter backup area, ephemeral data district.In electric device control program, embed the program that the read-write of SD card drives, SD card data fault-tolerant handling procedure.
Electric device is saved to by the parameter of dispatching from the factory the supplemental characteristic district of dispatching from the factory complete debugging before dispatching from the factory after.Electric device when carrying out field adjustable according to actual motion requirement configuration-system parameter (comprising electricity system, rated voltage, electric current, power of power supply-distribution system etc.); according to protection, require configuration protection parameter (defencive function that protection is used, the threshold value of protection and operating time of protection etc.), according to the characteristic of primary side secondary side voltage, current transformer, carry out parameter calibration parameter is set.During actual motion, electric device calls the comparing device inner parameter in SD card, and after fault-tolerant processing, complex protection device normally moves.When changing device more, the SD card of original device to be put into new equipment, the device operation that powers on, reads SD card parameter, reminds operating personnel to back up in new equipment, completes initialization, and normal function is carried out in device operation.When needs off-line analysis, manual operation is saved to temporary derangement data field in SD card by the batch data in setting-up time, then moves to external unit and carries out off-line analysis.When batch configuration parameter, use external unit to import in batches certain SD card, taking-up SD is stuck on peripheral hardware and completes off-line arrangement, puts back to electric device retaking of a year or grade, saves the running time.
