Description

SPECIFICATION A signalling system for a vehicle According to the present invention there is provided a signalling system for a vehicle, comprising: a first device for mounting on or in a vehicle, the device including a plurality of light-emissive devices; first means, for actuating selected ones of the light-emissive devices to display a message; and second means, for supplying the first means with control information to actuate such selected ones of the light-emissive devices in accordance with input information characteristic of the message to be displayed.

The said first device could be for mounting on the roof of a vehicle.

The said light-emissive devices could be incandescent lamps.

The said light-emissive devices could comprise arrays of such devices, the devices of each array being selectively actuatable for displaying an alpha-numeric character. In this case, the said first means could comprise a respective interface circuit for each array.

The said second means could comprise a microprocessor storing information for actuating selected ones of the light-emissive devices in dependence on different messages which may be displayed. In this case, the second means could further comprise a device (for example a push-button device), within or without the vehicle, for supplying the microprocessor with information characteristic of such different messages. Such -a push-button device could be in the form of hand-held keyboard unit.

The present invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 shows a signalling unit for mounting on the roof of a vehicle, and its hand-held operating unit; Figure 2 shows the signalling unit on the roof of a vehicle; and Figure 3 shows electronic circuitry of the signalling unit in block diagrammatic form for controlling the unit via the hand-held unit.

The system to be described includes two units, namely a 15 character signalling display unit for mounting on a vehicle roof and a remote hand-held keyboard control unit located within the vehicle.

a) Display Unit The display unit 1 comprises a housing 2 of polycarbonate type material which houses an aluminium lamp assembly panel 3. There are fifteen identical lamp arrays 4, to 4,5 attached to the panel 3, to provide for a fifteen character alpha-numeric display. Each array comprises a 5 row by 5 row matrix of 12 volt, 5 watt incandescent bulbs (25 lamps per character) retained by bayonet-type lamp holders hardwired to respective ones of interface printed circuit boards 5, to 5its, mounted at the bases of the arrays.

Each interface printed circut board (PCB) will decode character select instructions received from a main microprocessor based printed circuit board 6, mounted adjacent the display panel 3 in the unit 1.

The main microprocessor printed circuit board 6 will process all instructions from a hand-held keyboard unit 7 and also contains a programmable read only memory (PROM) integrated circuit 8 which contains all the predefined messages to be displayed. The PROM 8 is mounted in a 'zero insertion force' (ZIF) connector, thus enabling future 'change of message' requirements to be carried out by simple and easy removal/replacement of the PROM.

A lamp diffuser panel, red in colour, masks all bulbs and printed circuit boards, and provision for fitment of loudspeakers 9 for audible signalling is made within the housing 2 (which additionally or alternatively may include searchlights). Additional warning lamps 10 may be incorporated at opposite ends of the display panel.

The display unit 1 is powered from the vehicle's battery (heavy duty type) either by a permanently wired installation, or via a cigar lighter or similar device.

The display unit may be available in two versions, namely a permanently mounted unit attached to the vehicle roof or a removable unit attached to a 'clamp on' type roof-rack assembly 11 (see Fig. 1). Anti-vibration rubbers may be incorporated in both types of mounting arrangement.

b) Keyboard Unit The hand-held keyboard unit 7 has a liquid crystal display 12, providing verification of the main display message as displayed by the lamp arrays 41 to 415 and determined by the code for that message sent to the microprocessor board 6 by pressing a sequence of push-button switches of the unit 7. The keyboard unit 7 is connected to the display unit 1 by means of a telephone-type extending cable 13 fitted with a weatherproof connector assembly.

Ten of the push button switches are numbered 0 to 9 and allow selected ones of up to 100 different messages to be displayed. A printed message sheet defining each code and the related message may be attached to the rear of the keyboard unit.

A variable intensity switch for the lamps is incorporated into the keyboard unit 7 and also a switch for testing the lamps. Also, switches may be incorporated into the unit 7 for enabling the message to "roll" or flash/repeat.

The display unit 1 could alternatively be mounted on the boot or the rear parcel shelf of the vehicle for example.

Instead of being incandescent lamps, the light-emissive devices could be light-emissive diodes for example.

Claims (10)

2. A system according to claim 1, wherein the said first device is for mounting on the roof of a vehicle.
3. A system according to claim 1 or 2, wherein the said light-emissive devices are incandescent lamps.
4. A system according to any preceding claim, wherein the said light-emissive devices comprise arrays of such devices, the devices of each array being selectively actuable for displaying an alpha-numeric character.
5. A system according to claim 4, wherein the said first means comprises a respective interface circuit for each array.
6. A system according to any preceding claim, wherein the said second means comprises a microprocessor storing information for actuating selected ones of the light-emissive devices in dependence on different messages which may be displayed.
7. A system according to claim 6, wherein the second means further comprises a control device within or without the vehicle, for supplying the microprocessor with information characteristic of such different messages.
8. A system according to claim 7, wherein the said control device comprises a push-button device.
9. A system according to claim 8, wherein the push-button device comprises a hand-held keyboard unit.
