Definitions

  • This invention relates to a centralized system for monitoring the functioning of peripheral appliances, used in particular for emergency lighting lamps.
  • Telematic systems are becoming increasingly widespread in domestic and office environments for feeding control codes, data and information to a plurality of peripheral appliances (lamps, televisions, chronothermostats, electronic processors), the operation of which is programmed on the basis of instructions previously imparted by the user, or which are switched on when particular events occur.
  • peripheral appliances lamps, televisions, chronothermostats, electronic processors
  • Systems are also known for the diagnosis or self-diagnosis of the operation of such installations (by means of microprocessors able to carry out verification tests on peripheral appliances and handle the connection, with visual display of the information obtained), as are methods for monitoring and power supply centralization, systems for enabling and disenabling the operation of peripheral appliances, and procedures for remote switch-on, switch-off and programming.
  • an electronic control unit can communicate with each peripheral appliance by periodically executed interrogation operations. If one or more appliances of the installation cannot be reached, this abnormality is signalled by displaying an error message on the control unit monitor.
  • centralized function monitoring systems of the known art occupy a working space which it would be advantageous to reduce because of complexity of the cabling, which includes wires carrying the supply to the various devices and bus connection lines for transferring information and data between system circuit blocks and the microprocessor.
  • An object of the present invention is therefore to provide a centralized system for monitoring the functioning of peripheral appliances which obviates the aforesaid drawbacks, ie which enables an installation to be assembled within a smaller working area than the known art by virtue of being able to use a smaller volume of cabling, while at the same time ensuring the functions, the connections, the technical performance and the facility for expansion of the system, and complying with current electrical regulations, these being typical characteristics of known centralized systems.
  • a further object of the present invention is to be able to install said centralized system on existing electrical installations, without having to modify either the system or the existing installation.
  • a further object of the invention is to provide a centralized system for monitoring the functioning of peripheral appliances which is of simple and economical construction without having to use complicated or costly procedures, achieved by using standard circuit arrangements and known electrical and electronic components.
  • the centralized system of the present invention comprises an electronic control unit which supervises the operation of a plurality of peripheral appliances of electrical and electronic type (lamps, chronothermostats, televisions, electronic processors) to check their state of operation, to check the charge level of the storage batteries present internally and to command the enabling or disenabling of their functions (switching-on, programming, switching-off).
  • a plurality of peripheral appliances of electrical and electronic type lamps, chronothermostats, televisions, electronic processors
  • Communication between the electronic control unit and the peripheral appliances is achieved using digital information and data transmission of carrier type along the (220 Volt) line of the supply mains of the centralized system.
  • This characteristic enables the system to be installed by simply plugging the peripheral appliances into appropriate current sockets without having to add any communication line or dedicated digital buses.
  • the electronic control unit comprises within itself all the system control functions and is able to recognize the appliances installed, so extremely simplifying the configuration of the system during installation.
  • each appliance is identified unambiguously. This enables separate installations and systems to share the same line of the supply mains.
  • the reference numeral 10 indicates the electronic control unit, which is connected via the electrical line 90 of the supply mains 30 to a series of peripheral appliances 20, 20A, 20B, 20C, 20D, 20E, 20F, which can be chronothermostats, lighting lamps, electronic processors, or electronic transmitting or receiving devices.
  • the number of said appliances 20, 20A, 20B, 20C, 20D, 20E, 20F can vary according to user requirements.
  • the maximum number of appliances 20, 20A, 20B, 20C, 20D, 20E, 20F which can be connected is fixed at 255 (this figure is linked to the fact of forming, together with the control unit 10, a number which is a power of 2, within the framework of a digital signal transmission in bits per second).
  • the electronic control unit 10 is advantageously provided with a liquid crystal display screen, a printer and a keyboard usable by the user for keying-in commands.
  • the entire centralized system can be integrated within another system with more extended functions, to provide remote monitoring of the peripheral appliances 20, 20A, 20B, 20C, 20D, 20E, 20F via the telephone line 40, which is connected to the control unit 10.
  • the connection is made by two connectors per serial line (of standard RS232 type) positioned on the rear of the electronic control unit 10, which in this manner can communicate with electronic processors 70 and printers 80 via the modem 50, 50A.
  • the electronic control unit 10 is also equipped with a rechargeable Nickel-Cadmium storage battery providing 3 hours of self-sufficiency in the absence of voltage at the supply mains 30.
  • each lamp is able to provide emergency lighting even if communication with the control unit 10 is interrupted or voltage is absent at the supply mains 30 (provided said lamp has not been previously disenabled by the control unit 10 following a command imparted by the user via the keyboard).
  • Each peripheral appliance 20, 20A, 20B, 20C, 20D, 20E, 20F is provided with two LEDs, which indicate the state of operation of the system.
  • the first LED green light
  • the second LED two-colour
  • the centralized system operates as follows:
  • the user installs the appliances 20, 20A, 20B, 20C, 20D, 20E, 20F and the control unit 10 in their final positions and, using the keyboard of the control unit 10, initiates the recognition process.
  • control unit 10 assists the user in executing the required functions by displaying on the display screen selection menus representing a logical association between the commands which can be executed and the keys to be pressed.
  • display screen selection menus representing a logical association between the commands which can be executed and the keys to be pressed.
  • Access to the keyboard of the electronic control unit 10 can be prohibited to an unauthorized person by using an appropriate combination key present on the rear of the casing.
  • Within the control unit 10 there is a clock which maintains the time set by the user for a period exceeding 12 months, the configuration data remaining indefinitely in a permanent memory.
  • the electronic control unit 10 On termination of the recognition process (based on the transfer of digital signals by carrier transmission along the line 90 of the 220 Volt supply mains 30), the execution time of which depends on the size of the system, the electronic control unit 10 displays on the screen the number of peripheral appliances 20, 20A, 20B, 20C, 20D, 20E, 20F identified and a list of the relative identification codes.
  • the recognition process does not interfere with the operation of any installations already installed on the same line 90 of the supply mains 30, and the operations involved in replacing, removing or adding appliances 20, 20A, 20B, 20C, 20D, 20E, 20F to an installation already installed and operating can be executed by simple commands keyed-in by the user via the keyboard of the control unit 10.
  • the information and data successively exchanged between the electronic control unit 10 and the peripheral appliances 20, 20A, 20B, 20C, 20D, 20E, 20F are dedicated to the implementation of the following functions:
  • the state of operation of the peripheral appliances 20, 20A, 20B, 20C, 20D, 20E, 20F is checked by the electronic control unit 10 either automatically or at the specific request of the user (by keyboard commands).
  • the period between two automatic verification tests and the time at which said test is carried out are parameters which are set by the user via the keyboard of the control unit 10.
  • the peripheral appliance 20, 20A, 20B, 20C, 20D, 20E, 20F is made to operate for about one minute.
  • the electronic control unit 10 senses any error indications and signals these to the user either on the display screen or by paper print-out.
  • the document produced by the control unit 10 indicates both the day and time at which the check was made, the type of fault and the identification of the appliances 20, 20A, 20B, 20C, 20D, 20E, 20F in which the abnormality was encountered (each appliance 20, 20A, 20B, 20C, 20D, 20E, 20F is identified by an unambiguous address, which identifies its position relative to a reference point within an overall graph of the installation).
  • the same peripheral appliance 20, 20A, 20B, 20C, 20D, 20E, 20F provides a local indication of the error by causing a red LED to blink.
  • the state-of-charge check on the storage battery associated with each peripheral appliance 20, 20A, 20B, 20C, 20D, 20E, 20F is similar in execution to the check on its operating state, but requires a longer execution time because it is required to verify that the installed appliances 20, 20A, 20B, 20C, 20D, 20E, 20F have a self-sufficiency in terms of electrical energy which conforms to the rating plate.
  • the appliance 20, 20A, 20B, 20C, 20D, 20E, 20F is in operation, and an associated microprocessor checks the state of the storage battery, recording any abnormality.
  • the electronic control unit 10 obtains the results from each peripheral appliance 20, 20A, 20B, 20C, 20D, 20E, 20F and displays them on the screen. It is also possible to produce a paper print-out showing the date and time of the check, the errors found and an identification of the appliances 20, 20A, 20B, 20C, 20D, 20E, 20F which have produced them.
  • a further visual identification of the defective peripheral appliances 20, 20A, 20B, 20C, 20D, 20E, 20F is provided by the appliances 20, 20A, 20B, 20C, 20D, 20E, 20F themselves by the blinking of the red LED.
  • the user is able to set the frequency of the automatic checks (from 1 to 99 weeks) and the time of their execution, or to require their immediate execution by means of an appropriate command to be fed to the electronic control unit 10.
  • the centralized system of the present invention can be integrated into a system with more extended functions or remote monitoring of the peripheral appliances can be achieved using a telephone line connected to the electronic control unit, to which electronic processors and printers are connected via modems.
