The base station data processor is able to analyse the recorded data for preventive maintenance prurposes.

Description

Vehicle Monitoring System
This invention relates to a system for monitoring and recording operating parameters of a vehicle.
Systems are known for acquiring and recording data in respect of the operating parameters of a vehicle and enabling this data to be analysed at a central or base station. In US patent 4 188 618, data in respect of e.g. vehicle speed, trip distance, engine r.p.m. and fuel consumption is recorded in a data memory on-board the vehicle. When the vehicle reaches a base station, this data is transferred into a central computer of the base station, either by a direct cable connection which is made between the on-board system and a terminal of the central computer, or by a short-range radio transmission which is triggered by a proximity detector when the vehicle arrives. In the system disclosed in South African patent 8 401 416, data in respect of vehicle operating parameters is recorded in an on-board solid state acquisition unit, which can be removed when the vehicle reaches a base station and connected into a central computer for analysis of the data. However, it will be appreciated that in these known systems, the vehicle operating data can only be acquired by the base station once the vehicle arrives at that station. Further, whilst the on-board system of South African patent 8 401 416 can determine and notify the driver if a sensed parameter e.g. engine oil pressure departs from a safe limit, in effect this is only an emergency indication that a fault has already developed and a safe limit has been passed, and provides little advance notice that a fault is starting to develop.
In accordance with this invention, there is provided a vehicle monitoring system comprising a unit fitted on board the vehicle which monitors and records vehicle operating parameters, a data processor unit located at a base station for analysing the data recorded by the on-board unit, and a radio transmission system for communicating the recorded data from the on-board unit to the base station data processor whilst the vehicle is on the road remote from the base station.
Thus the acquired data can be communicated from the vehicle to the base station at any desired time. The data transmission may occur automatically at fixed intervals, or when demanded by the base station processor: for the latter purpose the base station may poll different vehicles in turn over the radio transmission system to cause the data recorded on each vehicle to be transmitted back to the base station processor. The recorded data may be transmitted from the vehicle to the base station at least one a week and typically once or twice a day.
The data which is recorded on the vehicle preferably includes road speed, engine speed (r.p.m.), distance travelled, fuel consumption, cylinder head temperature, exhaust gas temperature, engine and transmission oil pressures, and water temperature: all of this data is recorded in real time.
The base station processor is able to analyse such data for the purpose of managing a fleet of vehicles. Further, certain data (vehicle speeds, distances travelled, engine r.p.m.) can be processed to determine a proficiency rating for the driver, which can be useful particularly when training the driver. For example, the exhaust gas temperature should remain substantially constant if the driver is driving correctly (e.g. keeping the vehicle in correct gear under different conditions), and so it is useful if the base station processor analyses variations in the exhaust gas temperature.
Further however, the base station processor preferably analyses the data from each vehicle to derive vehicle diagnostic or preventative maintenance reports. For example, the base station processor can determine....if any recorded parameter departs from a predetermined value for greater than a predetermined time period (e.g. if the cylinder head exceeds a predetermined temperature, or if the oil or water pressures fall below a predetermined level). In this manner, the base station processor can provide a report giving an early warning that the vehicle- is developing a fault and should be brought in for maintenance before long. For a similar purpose, the processor may analyse the pressure and temperatur variations to determine any trends which may indicate tha the vehicle is developing a fault.
An embodiment of this invention will now be described by way of example only and with reference to the accompanying drawing, the single figure of which is a schematic block diagram of a vehicle monitoring syste ain, accordance with the invention.
Referring to the drawing, there is shown a vehicle monitoring system comprising a data processor unit 10 located at a fixed base station and including a radio transmitter/receiver 12, data store 14, keyboard an display unit 16 and a printer 18. The system further includes a data acquisition unit 20 which is fitted on¬ board a vehicle and includes sensors 22 which monitor the various vehicle parameters in real time, a solid state .data store 24, a central processing unit 26 and .a radio transmitter/receiver 28. In practice the overall system will comprise a plurality of data acquisition units on¬ board respective vehicles in the fleet.
In operation, the sensors 22 on each vehicle continuously monitor the sensed parameters and a record is made in real time in the data store 24 under control o£ the. central processing unit 26. The sensed and recorded data includes road speed, engine speed (r.p.m.), distance travelled, fuel consumption, cylinder head temperature, exhaust gas temperature, engine and transmission oil pressures, and water temperature.
The recorded data is transmitted by radio to the base station as desired. For example, the data may be transmitted automatically from each vehicle at regular intervals of time. Alternatively, the data may be transmitted when "called" by the base station; preferably the vehicles are polled in turn either on demand or at regular intervals. The data can be transmitted by radio to the base station whilst the vehicle is on the road and therefore remote from the base station.
The base station processor analyses the received data for each vehicle, firstly for fleet management purposes and secondly for preventative maintenance purposes. As described above, the data can also be processed to determine a proficiency rating for the driver. Reports which are determined by the processor are displayed on the display unit 16 and/or printed out by the printer 18.
For the preventative maintenance function, the processor 10 analyses the data for each vehicle and determines and reports any variations or abnormalities or trends which indicate that the vehicle may be developing a fault. For example, the pressure and temperature variations are analysed for any particular trends; also various parameters are monitored to determine if they depart from a predetermined value for greater than a predetermined time period (e.g. if the cylinder head temperature exceeds a given value for an excessive time, or if the oil pressure falls below a given level for an excessive time). Any report provided by the processor may indicate the suspected fault and require the vehicle to be brought in for attention ahead of its scheduled service. If any report indicates an unsafe operating condition, this may be communicated directly to the driver over the radio transmission link.
It will be appreciated that the system which has been described enables the data recorded on each vehicle to be made available promptly and analysed at the base station whilst the vehicle continues working without the need for the vehicle to call in at the base station or at any outlying stations or depots. Further, the data can be analysed to provide early warnings that the vehicle is developing a fault, so that preventative maintenance can be practised.
Further however and in accordance with a development of the system, a facility for automatic recalibration in respect of road speed may be provided. Thus, two radio beacons can be set up at a predetermined distance apart on selected roadways, directing their beams across the road. When a vehicle which has a system in accordance with the invention passes along such a roadway, it responds when traversing the radio beam of the first beacon to count the pulses from the road speed detector until the vehicle traverses the radio beam of the second beacon. From a knowledge of the distance between the two radio beacons, the speed of the vehicle is determined automatically and the system is recalibrated with respect to the pulses delivered from the road speed detector. With recalibration variations in the diameter of the roadwheel can be prevented from affecting the measured roadspeed.
