Definitions

  • Such locks are, for example, used to control access to cash dispensers.
  • One of them is described in the US patent 5,488,660.
  • the control means that it includes allow a person must intervene in the distributor to enter an entry code.
  • the microprocessor processes this code and, when it considers it to be compliant, commands or authorizes the opening of the lock. So people responsible for recharging, maintaining and checking the dispenser can Easy access is secure.
  • control means do not have no display.
  • the date setting of the clock must therefore be done at the blind. This involves control operations making manipulation complex. In addition, a risk of error cannot be excluded.
  • the main object of the present invention is to produce a lock provided a low-cost clock, simple to handle and giving the date of safe way.
  • the counter has an input increment linked exclusively to the time base, and a linked output, at least medially, to the microprocessor and to the memory.
  • the contents of the clock counter cannot be modified, otherwise by the pulses from the time base.
  • the date it contains can only have a relative value, since it there is no way to adjust the content to the current date.
  • the lock transmits to a laptop a list interventions with their dates.
  • the logic of the system structure the data by going back in time, the first information of the list corresponds to the current audit.
  • the date displayed for this intervention can therefore without further comparison by the computer with its internal date, to define a correction offset that will be applied to all data recorded, and thus know the exact date of all interventions reported by the audit.
  • the content of the counter is modified and can take any value. This is without prejudice to the accuracy of the information contained in the audit if the computer has memorized the last coefficient. If it has not been done, just know a date certain to redefine this coefficient, for example that at least one event reported by the previous audit is found in the next audit, or that we know the exact date of at least one intervention performed before battery replacement.
  • the device according to the invention further comprises a circuit initialization connected to the counter by an initialization input and arranged way that it puts the meter in a predefined state when the clock is power up. In this way, by analyzing successive dates concerning the interventions reported by the audits, it is easier to define when possible malicious power interruptions have possibly performed. Note that the placement of the battery will, of course, be recorded as an intervention and, as such, mentioned in the audit.
  • the clock as defined above can be fitted with a standard counter, comprising parts respectively defining seconds, minutes, hours, days, months and years. It is also possible to use a decimal or binary counter, whenever the computer has to, anyway, perform a mathematical operation to set the date in the current calendar.
  • the present invention also relates to a method for carrying out an audit. a lock as defined above.
  • the implementation of this process requires a computer with an internal clock that determines the date current.
  • the lock as shown comprises a source of electrical energy 10, a clock 12, an electronic circuit 14, control means 16 and a lock 18.
  • the energy source 10 is generally produced by means of one or more several alkaline or lithium batteries, as available on the trade. They are chosen so that they can provide normal operation for about a year.
  • the clock 12 has a time base, generally formed by a quartz resonator 20, a frequency divider 21, a counter 22 and a initialization circuit 24. Quartz 20 corresponds to those commonly used in watches. It ensures accuracy of the order of a second per day, which is more than enough for such an application.
  • the counter 22 can also be of the type used in watches, with division up to year level, possibly month level, or work in seconds or minutes, in binary or decimal code. It has a first input 22a, of incrementation, connected to the frequency divider 21, and through it to the quartz resonator 20 which generates the object pulses of the counting. A second input 22b, for initialization, is connected to the circuit initialization 24.
  • the initialization circuit 24 is connected to the battery 10 and arranged so that when it is put into service, the state of the counter 22 is perfectly defined. It will advantageously be zero if the counter relates to only minutes or seconds, on the first day of the first month, at 0 o'clock with a classic hour meter.
  • the electronic circuit 14 includes a microprocessor 26, a memory of type ROM 28 containing the programs of microprocessor 26, one RAM 30 type memory, used to store transient values and a memory of type E2PROM 32, making it possible to memorize, so rewritable, information to be kept, even in case of battery failure 10. This is particularly the case for information relating to to the various interventions carried out on the lock and which are the subject audits.
  • the electronic circuit 14 further comprises connecting means, formed for example a connector 34, allowing to connect a computer exterior shown schematically at 36 and intended to record an audit.
  • the control means 16 are formed by a keyboard making it possible to address orders and give information to the microprocessor 26, for example the introduction of an access code or an order to initialize an audit.
  • the lock 18 includes a motor 38, powered by electronic electronics. power not shown in the drawing and controlled by the microprocessor 26, and a rod 40 driven by the motor 38.
  • the microprocessor 26 controls the sending of information contained in the memory 32 relating to the interventions performed on the lock, starting from the most recent.
  • Each train of data relating to an intervention includes the date of the intervention in the scale specific to the clock 12 of the lock, the type of intervention and a code to identify the person who performed the intervention.
  • the intervention in progress is transmitted first.
  • the computer knowing the current date can thus calculate a correction offset which, added to the date stored in the lock, gives the current date for each of the interventions undertaken.
  • the offset is kept in the computer, it is possible to verify that there is no interruption in the clock supply. It is also possible to determine the progress of the internal clock of the lock.
