Definitions
- This invention relates to the monitoring of electric lighting networks, and the management thereof.
- Electric lighting networks and comparable systems are characterised by very wide-ranging and branched electricity distribution providing energy to each individual lamp or to each individual user item within such systems.
- the state of the art currently comprises monitoring systems by which certain parameters signifying proper operation of the peripheral user items are obtained locally at each user item, and fed by a carrier wave system, via the cables powering the user items, to a central microprocessor programmed to detect discordances in the parameters and convert them into signals indicating the type of fault or abnormality of said peripheral units.
- a further limitation of known systems is that they can be activated only when the user items are in operation.
- the object of this invention is to remedy the deficiencies of known systems by means of a reliable, low-cost monitoring system of simple operation.
- Figure 1 shows the scheme of an electric lighting upright forming part of the lighting system monitored by the invention.
- Figure 2 shows the circuit block scheme of the transmission unit associated with the upright.
- Figure 3 shows the circuit block diagram of the central control unit.
- the figures show an upright 100 i carrying at its end a lamp 10 i , where i lies between 1 and n, for a lighting network comprising n uprights.
- the lamp 10 i can be either of the mercury vapour type or of the sodium vapour type, in this latter case it being associated with a usual reactor 12 i and a suitable ignition system, not shown in the figure.
- the power circuit of each individual lamp 10 i can also comprise a rephasing capacitor 13 i .
- each lamp there is located a transmission unit 2 i , the block scheme of which is shown in Figure 2.
- the transmission unit 2 i comprises a microprocessor 25 i , which in the illustrated example is a Texas Instruments microprocessor type TMS370C6C2 controlling a carrier-wave transmitter-receiver 26 i , which in the illustrated example is a National transceiver type LM1893.
- a microprocessor 25 i which in the illustrated example is a Texas Instruments microprocessor type TMS370C6C2 controlling a carrier-wave transmitter-receiver 26 i , which in the illustrated example is a National transceiver type LM1893.
- the microprocessor 25 i receives data regarding the line and lamp voltage and current, and regarding the power factor associated with the lamp 10 i , these data being measured by known devices positioned within the block 23 i connected to the lamp feed branch 41 i .
- the microprocessor 25 i also controls the electromechanical or static relay represented by the block 24 i , which switches the lamp 10 i in or out.
- the transmitter-receiver represented by the block 26 i sends/receives signals to/from the feed line via the module 21 i .
- the block 22 i represents a carrier-wave blocking filter, the function of which is evident.
- the central unit 3 comprises a central microprocessor 34, which in the illustrated example is an Intel microprocessor type 80C32, this being able to analyze and compare the data originating from the microprocessors 25 i .
- the microprocessor 34 receives data from the carrier-wave transmitter-receiver 33 via the module 32, which is similar to the module 21 i .
- the system operates as follows.
- the central unit 3 firstly feeds the entire lighting network, with the electromechanical or static relays 24 i initially open.
- each electromechanical or static relay 24 i in each upright 100 i is locally measured by the devices contained in the blocks 23 i .
- microprocessor 34 of the central unit If the microprocessor 34 of the central unit encounters no abnormality, it feeds a signal to all the local microprocessors 25 i , which close the respective electromechanical or static relays 24 i , to cause the lamps to light simultaneously.
- the central microprocessor 34 receives data regarding the current absorbed by each lamp and the power factor, from each peripheral microprocessor 25 i .
- the local microprocessor 25 i can temporarily or definitively interrupt power to each individual lamp 10 i , to prevent its maloperation causing damage to the entire network.
