Definitions

  • This invention relates to methods and devices for the collection of data or samples from identified locations.
  • a good example is the shipping industry.
  • the hull In a cargo vessel, the hull must be regularly surveyed for corrosion and fatigue; the enclosed volumes of the holds may need to be monitored for the buildup of toxic or explosive gases; and the condition of numerous items of safety-related equipment must be systematically monitored and all of the resulting information recorded.
  • the railway industry it is vital to examine, perhaps thousands of miles of tracks and points regularly and systematically for signs of wear and incipient failure and to record evidence of this inspection and maintenance. Regular monitoring and sampling is also necessary in air conditioning and water supply systems to detect the presence of biological contaminants.
  • Verifiable and consistent record keeping in relation to such inspection regimes is equally important, particularly where the failure to identify and respond to a hazard could expose the operator of the system or equipment to the risk of causing damage to people or to the environment and to statutory liability.
  • the present invention provides a portable device for recording location-specific data, including data input means and data storage means; characterised in that the device is used in association with a plurality of identity tags, each tag being fixed at a location where data are to be recorded, and the identity of each tag being stored in association with its location; and in that the device includes identity tag reading means for reading the identity of each tag, and means for recording the tag identity in association with the input data.
  • a portable device for identifying location-specific samples including means for generating identifying labels for attachment to the samples; characterised in that the device is used in association with a plurality of identity tags, each tag being fixed at a location where a sample is to be collected, and the identity of each tag being stored in association with its location; and in that the device includes identity tag reading means for reading the identity of each tag, and means for associating each tag identity with a respective label.
  • a third aspect of the invention there is provided a method of verifiably recording location-specific data, comprising the steps of:
  • the method and device facilitate the implementation of a regime of data collection or sampling, wherein each data item or sample can be verifiably linked to the location where it was collected.
  • a number of identity tags preferably contact identity tags, are first affixed, each to a location where data is to be recorded, and the location of each tag is recorded in association with its tag identity in a database.
  • the database may be located on one or more central computers or servers, and may be password protected or otherwise secured and verified by independent authorities.
  • the personnel carrying out the inspection visit each location where data or samples are to be collected, and read the tag identity of the identity tag in each location using a portable identity tag reader which is integrated with a data input device or label printer as further described below.
  • the data collected which may be for example a voice recording, a photograph, a gas sample analysis, or any other type of information are then input into the data input device and stored in a memory in association with the tag identity, enabling the location of the input data to be decisively determined from the database.
  • a label is printed for affixture to the collected sample as further described below.
  • contact memory type identity tags rather than remotely interrogated tags offers the advantage that the personnel carrying out the inspection are compelled to reach the location of the tag in order to collect the data, precluding any possibility of false recording or inadequate inspection.
  • a contact identity tag may be fixed to the floor of the locker, compelling the user of the device to remove the contents of the locker in order to gain access to the tag. Reading of the tag thus equates to certification that the precise location in question has been visited.
  • Verification of an inspection regime implemented in accordance with the invention may be accomplished by the verifying authority or inspector periodically visiting each identity tag and recording its tag identity and location, then cross checking these against the database.
  • the integrity of the database and device according to the invention may be verified by means of password protected software, mechanical seals on the casing of the device and equivalent means.
  • the device and method of the invention thus enable the operator of the inspection regime to show compliance with his statutory obligations to inspect and maintain whilst ensuring that his maintenance and inspection personnel are carrying out their duties conscientiously.
  • the date and time at which the data were input into the device are also automatically recorded in association with the data and the tag identity.
  • the identity of the individual carrying out the inspection is recorded, for example by reading an identity tag assigned to that individual and also storing this tag identity in association with the input data.
  • This enables the progress of the inspection to be monitored, whilst by cross checking the time taken by different personnel to carry out the inspection of a given set of locations, irregularities in the inspection may be identified. This further enhances the integrity of the collected data and provides proof of presence of each inspection worker, which may also be correlated with his access privileges, such as authorisation to open and inspect railway signalling junction boxes.
  • the tag identities and locations are stored on a central database and organised in accordance with a maintenance or inspection schedule.
  • a subset of tag identities is then downloaded from the central database as each inspection round falls due, preferably by placing the tag reader and data input device into a data transfer cradle so that the subset of tag identities is downloaded to a separate, local database or memory located in the device.
  • Information identifying each tag location is preferably stored in the central database in association with each tag identity and downloaded to the handheld device.
  • the user of the device By viewing the subset of tag identities and location information as a list, for example by means of drop down menus on a touch screen on the device, the user of the device is able to plan his round of inspections in the correct order.
  • the stored location information relating to it is automatically output - for example, displayed on the screen or played as an audible instruction set - helping the user to carry out any special instructions associated with the tag.
  • Special instructions or conditions may be stored and downloaded in association with each tag identity, and may for example program the data input device to accept data only where the conditions are fulfilled.
  • the conditions may specify a maximum time period which may elapse between reading the tag and inputting the data. This allows the individual using the device enough time to read a tag and then input the data — for example, take a gas sample - whilst ensuring that the gas is sampled at the tag location.

  • a data recording device is formed as described above as a portable module 1 with an integral identity tag reader, means for inputting data and an internal memory for storing the input data in association with the identity of the identity tag which is read by the tag reader.
  • the module 1 is preferably small enough to be carried about easily by the user, and of a rugged construction suitable for use in demanding outdoor, marine or industrial environments, and is conveniently equipped with loops 2 for attachment to the user's body.
  • the internal memory or local database also stores a list of tag identities and associated information as described above.
  • Electronically readable tags typically comprise a microchip or other data carrying device which is encoded with an identity, such as a binary number which is unique to that tag, together with means for reading the tag identity remotely, for example by means of radio frequency interrogation, or by contact.
  • Electronic identity tags may carry other information in addition to the tag identity, and may also be writable and erasable. Passive tags benefit in comparison with active tags from enhanced reliability and longevity since no power supply is required, and are hence preferred.
  • a particularly preferred form of tag comprises a small passive button type contact identity tag 100 containing a microchip or the like which is encoded with the tag identity.
  • the button is robust, impervious to moisture and capable of withstanding long exposure to harsh environments, and in use may be attached to a surface as further described below by any convenient means, such as gluing its base 103, capturing its flange 104 behind a riveted collar or the like.
  • the use of contact rather than remotely interrogated tags also reduces power consumption and allows the tag reader to be more compact, enhancing portability, and avoids the potential for inadvertent reading of the wrong tag.
  • the contact tag 100 is readable by contacting an inner terminal 101 simultaneously with the tag casing 102, which forms an outer terminal, by means of a probe 10 which is provided on the outer casing of the device 1.
  • the probe 10 has two pointed contacts 11, 12 which in use are pressed against the terminals 101, 102 of the tag so as to form an electrical circuit.
  • the pointed contacts 11, 12 enable the probe in use to penetrate any accumulated dirt or paint film so as to contact the tag, whilst the durable construction of the button type tag 100 allows any gross contamination to be scraped from the surface of the tag without damaging it.
  • tag and tag reader may be selected for use in accordance with the invention.
  • a barcode reader might be used instead of or in addition to the contact tag reader and probe 10; however, barcoded tags placed in outdoor or marine environments are vulnerable to being painted over or washed or scraped off.
  • a remote tag reader is used in addition to or in place of the contact tag reader, and preferably is capable of reading an RFID or other passive electronic identity tag over a short, defined range - for example, ten centimetres, two metres or ten metres - by radio frequency interrogation or equivalent means.
  • This enables the tag to be read even where for example it is obstructed by debris; however, the added convenience for the individual using the device entails added uncertainty for the operator of the plant or equipment, since the user may read the tag without closely inspecting the location to which it is affixed.
  • a remote tag reader and remotely readable tags may therefore be preferred; preferably the tags are readable only over a short, defined range.
  • contact type identity tags are preferred since this ensures that the individual carrying out the inspection has gained access to the precise location where the inspection is to be made.
  • a contact type tag may include a remotely sensed element, and either the tag reader or the tag itself may incorporate a sounder or flashing light which indicates when the tag is in range. This assists the individual carrying out the inspection in locating the tag.
