Abstract
Description
- The present invention relates to a system for controlling and/or recording and/or indicating of elapsed time and/or of events following one another in the time.
- More particularly, the present invention relates to an admittance control system which is able to confidentially store in a memory the displacements and/or the passages of persons within a given place or a given area.
- In some places, e.g. building yards, hotels, supermarkets, joinery workshops etc., it is necessary to have an admittance control system which is able to confidentially record the displacements and/or the passages of persons, so that the situation of the presences within said place is continuously available.
- A system which is normally used in a plurality of working places is constituted by the so-called "presence booklets", which are manually filled out and which allow the presences of operators to be checked.
- However, such system involves disadvantages and drawbacks, since it causes data writing and/or transcription errors, and it causes a large waste of time and work to the presence checking operators (especially in the case where the staff is numerous); furthermore, the data may easily be modified by persons who do not act in a real good faith.
- Thus, such system may not be considered as reliable.
- Another known presence control system, which is for instance used in building yards, makes use of a magnetic card which is associated to each operator, and of suitable computing means (e.g. a PC) which are installed by the yard and which may elaborate, for instance, the entry and exit data or the working time of a given person who would insert said magnetic card in a suitable reading device.
- Such system is certainly more advantageous in respect of the system making use of presence booklets; however, it also involves disadvantages and drawbacks which greatly limit the possibilities of using this system.
- In fact it requires the presence, for each individual yard, of a fixed PC suitable for processing the data, of specific PC operators, and of a magnetic card reading device; on these grounds, such system is relatively little used, since it does not allow any flexibility of use; as a matter of fact, this system may only be individually used for a single yard, and it requires the installation of a specific PC for each individual yard.
- This substantial irremovability causes, from an economical point of view, very high costs in order to check, for instance, the presence of a working team acting in different yards during a given lapse of time.
- EP-A-0 139 340 discloses a system as specified in the preamble of claim 1. This prior art system is used for recording the working times of truck drivers. It comprises a unit that is fixedly mounted in the truck, in which each driver can insert an identification card. The unit comprises a date clock circuit and a microprocessor with associated memory. The unit associates identification data read from an inserted card with data from the date clock circuit and records these data in a removable data cassette in the form of a RAM buffered by a battery.
- IBM Technical Disclosure Bulletin, vol. 23, No. 7A, December 1980, page 2744 discloses a data recorder with time stamping. Said recorder comprises a portable data collection device including a scanner for reading data from a magnetic card and recording said data in a magnetic tape cassette. A time-of-day and data calculator within said device provides a coded representation of date and time to be recorded, along with each data entry made by said scanner; periodically said cassette is placed in a tape reader connected to a control processing unit in which the collected data are processed and interpreted.
- Another identification system is disclosed in document US-A-4,639,583; in this case too, collected data are associated to a time code and recorded in a magnetic tape cassette which may then be placed in a control processing unit for further data evaluation.
- Document US-A-4,323,771 discloses an automated employee time and attendance system having a central processor and a plurality of sub-systems which are capable of providing data used by the central processor in payroll determination. In this case the collected data are temporarily stored in a magnetic disk.
- Document US-A-3,889,103 discloses an electronic timer for producing a printed record of time intervals. The timer includes manual, photoelectric, acoustic signal, and other trigger source actuation and can simultaneously measure and record two or more events on separate channels and produce printed records of each. The apparatus is powered by self contained batteries which power a clock oscillator, all electronic timing circuitry and the record or paper tape mechanism.
- The systems disclosed in said background art documents involve some major disadvantages which strongly limit their performances.
- Actually, some of these devices have to be powered by connecting them to the mains, in order to provide for a continuous and stabilized electrical supply of the different mechanisms of the tape or disk recorders. Thus, they cannot be defined as "portable", since their use is always dependent on the presence of an electric socket for connecting them to the electric network. In the case where these devices were provided with batteries, many other problems could arise, since tape and disk recorders are characterised by relatively high electrical energy absorption rates; therefore, a daily use of these known devices would involve a frequent replacement of the batteries and, in any case, a relatively high device weight.
- The present invention aims to obviate to the disadvantages and drawbacks which are typical of the background art, and to provide, thus, for a system for controlling and/or recording 1 and/or indicating of elapsed time and/or of events following one another in the time which is transportable from one place to another, which has an extremely low electrical energy absorption rate, which allows a centralized processing of the available data and which warrants the confidentiality of the detected data.
- This is achieved by means of a system having the features specified in the main claim 1.
- The dependent claims describe advantageous forms of embodiment of the invention.
- The system according to the invention provides for the use of a completely autonomous unit, which is fed by a battery and which is easily transportable from one place to another one, said unit comprising a reading device suitable for receiving a series of data provided in a suitable data carrier which is associated to a given person, and a static memory suitable for recording said series of data.
- According to a feature of the invention, said static memory is provided with autonomous feeding means and may be removed from said unit in order to be inserted into a centralized data processing device which processes the data coming from said static memory, as well as the data coming from other static memories, and which provides for the presentation of the processed data in a visualized way or on a suitable carrier, e.g. on paper or on a magnetic carrier.
- According to an advantageous form of embodiment of the invention, said data carrier on which are recorded the data identifying the carrier itself and/or the data associated to a given person, is constituted by a key including an EPROM-type memory.
- Such key is inserted by the operator into a suitable reading device which is incorporated in said autonomous unit, said device transferring such data into the static memory which is removable from the unit.
- Once this static memory is removed from the autonomous unit and is inserted into the central unit, the program which is set in said central unit compares the data recorded in said memory to those which are relative, for instance, to the admittance permission of a given key inside of a given place, and it produces, in the most suitable way, the results of such comparison.
- In this way it is possible to check whether, for instance, a given key has been used for entering a yard for which the key had previously been entitled to or not.
- According to an advantageous form of embodiment of the invention, said autonomous unit is provided with a visual and/or acoustical signalling device, e.g. a pair of light emitting diodes and/or a buzzer, which allow the person who inserts the key into the reading device to immediately get from the autonomous unit a series of informations, e.g. about the carried out recording of the key data, or about the admittance approval into said specific place, or other.
- Moreover, according to another advantageous form of embodiment of the invention, the autonomous unit may be provided with a data inputting means (e.g. a keyboard) and with a data visualizing means (e.g. a monitor screen); such configuration allows an operator employed for using the autonomous unit to immediately carry out presence checks, either in a merely numerical form or by checking predetermined persons; therefore, it is possible to obtain in a visual way a general layout of the entries and exits in a given lapse of time.
- Other features and advantages of the invention will become apparent by reading the following description, given as a nonlimiting example, with the help of the figure illustrated in the annexed sheet, which shows a simplified layout of the apparatus constituting the system according to the invention.
- In the figure,
reference sign 10 generally indicates an autonomous unit belonging to the system according to the invention. -
Unit 10 is fed by means of asuitable battery 11, by way of example a rechargeable Ni-Cd buffer battery, and it comprises a pair ofreading devices suitable data carrier 12 which, in this case, is constituted by a key housing an EPROM-type memory on which some significant data are recorded, e.g. identification data of the respective key, or codes for identifying the person who inserts the key, or accession codes etc.. - According to the invention, each
reading device memory block 16 which may be removed from saidautonomous unit 10 and which respectively comprises a smart card provided with its own CPU in order to decode and to amplify the coded signals coming fromreading devices coupling block 16 tounit 10, and asuitable interface 17, e.g. a serial gate RS 232 for enabling a possible connection ofblock 16 to a central unit, advantageously to a PC. - Moreover, according to a first form of embodiment, the
removable memory block 16 is connected to a data displaying device 19 (e.g. a display or a monitor screen) and to a data inputting device 20 (e.g. a keyboard). - According to a second form of embodiment,
unit 10 is not provided with said data displaying and inputting devices; in this case,memory block 16 is connected to an indicatingdevice 18 comprising a pair of light emitting diodes (LED), whose operating way will be hereinafter disclosed in detail. - Furthermore, each
reading device key 12 is inserted into one ofreading devices - Alternately, the activation of the memory may be carried out by a suitable software.
- In the following a particular form of embodiment of the system according to the invention will be described, according to which the system is used for carrying out a presence check inside a working environment, e.g. a building yard.
- A
key 12, which respectively serves for entering and exiting the yard, and which is provided with a prerecorded carrier (e.g. a specific memory) carrying a series of informations for identifying the same key, is given each operator whose presence in the yard is authorized. - By the yard entrance there is an
autonomous unit 10 and each operator inserts his accession key into asuitable reading device 14. - In the case where
key 12 has been correctly inserted into thereading device 14, the same key operates the switch contained in the reading device, said switch closing then the feeding circuit ofbattery 11;unit 10 is then immediately ready, and the buzzer ofreading device 14 gives out an acoustic signal indicating that a key has been correctly inserted. - Alternately, the insertion of a key may run a suitable software program for recognizing the same key, said program recording and processing the data carried by the key.
- Now, according to a form of embodiment, a
visual signalling device 18 gives an indication about the fact that data have been recorded and/or about the operator accession permission to the yard. - Alternately, according to another form of embodiment, the autonomous unit is provided with a
display 19 and with akeyboard 20 by means of which a checking operator may directly and immediately verify the number of presences inside of the yard, as well as, for instance, the entry time and other significant data. - At the end of the working period, the operator inserts
key 12 intoreading device 15 and a procedure similar to the preceding one is repeated. - Thereafter,
memory block 16 may be removed fromautonomous unit 10 and it may be inserted into a central unit which, by means of a suitable software, specifically processes the data recorded by that autonomous unit, as well as the data coming from other possible autonomous units which were present by other yards, thereby giving the checking operator a graphical, or magnetical, presentation of the presence situation in a specific yard, or in a plurality of yards, relative to a predetermined lapse of time. - It appears to be evident that, in accordance to the installed software, it will be possible to verify and to ascertain the presence of each operator inside of one or more yards, thereby providing for each operator a personalized card bearing his presence periods.
- It may still be noted that, since
memory block 16 is provided with asuitable interface 17 allowing the block to be connected to a PC, of a fixed or of a portable type, a checking operator may at any time have available any kind of data processing relative to the presences inside of a given yard. - The invention has been previously described with reference to an advantageous form of embodiment thereof.
- However, it appears to be clear that the invention is certainly not limited to that form of embodiment; rather, it comprises several variants falling within its scope.
- By way of example, the apparatus may be directly connected either to an informatics network or to a printer.
- Moreover, although the keys which have been described are constituted by elements containing an EPROM memory, the invention comprises forms of embodiment according to which the keys are of another kind, such as for instance magnetic cards, badges, etc., as well as forms of embodiment according to which a single reading device is provided for each unit.
- It should also be clear that the system according to the invention may easily be adapted, according to different requirements, to carry out control operations differing from the disclosed ones.
- By way of example, the system may easily be adapted in order to check the time which has effectively been worked by specific operators; furthermore, the system is absolutely not limited to applications as the previously described one, i.e. for checking presences inside of building yards.
- In fact, the system may easily be adapted for carrying out controls and verifications inside of the most differents environments, such as for instance supermarkets, hotels, joinery workshops, small workshops, stores, laboratories, fashion-houses, purchasing centers, banks, saw-mills, transportation firms, firms operating in the field of assemblying and internal or external mantainance, wine cooperative stores, cleaning companies, bakeries, confectioner's shops, or for checking labourer's work etc.
