Definitions
- the present invention relates to a system and method for monitoring operating conditions in vehicles and distributed networks.
- the present invention relates to the field of safety and advanced maintenance planning of road and railway vehicles and distributed networks requiring large numbers of sensor nodes, and more specifically to a low-cost and low-power system and method for on board real-time detection of faults, abnormal operating conditions and other condition monitoring applications.
- Condition monitoring techniques are commonly used in many industries, including railways and road transport, to increase efficiency by enabling prognosis and implementation of advanced planning of maintenance tasks and to enhance safety by continuously diagnosing the asset health condition.
- the majority of condition monitoring systems used in railways are static wayside systems that record and analyse vehicle response and operational data of the trains that pass the static system. This wayside condition monitoring approach is inherently limited as is not able to provide continuous real-time diagnosis of individual vehicles, since it does not produce any information between sensing points, which is the majority of the time the vehicle is operating.
- WSN Wireless Sensor Networks
- a major limitation of condition monitoring WSNs deployed on-board railway vehicles is the lack of power supply and communications in the majority of unpowered rolling stock, and the difficulties associated with providing a power supply from a powered vehicle to an unpowered vehicle, thereby increasing costs and reducing the convenience of installing and operating such systems.
- the cost and difficulty of installing, operating and maintaining such systems is increased further when it is necessary to scale a distributed network to the order of thousands of sensor nodes to achieve significant monitoring capabilities, such as in railway operations. To achieve this sensor nodes forming the WSN must have efficient power managing or energy harvesting technologies to provide real safety and efficiency improvements.
- the individual cost of the sensor node hardware and installation must be low enough to allow massive WSN
- the present invention is directed to a sensor node system and method which may at least partially overcome at least one of the abovementioned
- the invention resides broadly in a method for monitoring operating conditions of a vehicle or infrastructure network, the method comprising the steps of: a) Associating one or more sensors with one or more vehicle components and/or infrastructure components; b) Acquiring measurements of one or more operating parameters of the one or more vehicle components and/or infrastructure components using the one or more sensors; c) Transmitting the measurements of the one or more operating parameters to an operating parameter monitoring device in a form including high frequency signals; d) Converting the measurements into an output signal message indicating the presence or absence of a fault in the one or more vehicle

- fault is intended to mean any of a vehicle component fault, the presence or absence of operating conditions outside normal and/or optimal operating conditions, trends in operating parameters and the presence or absence and/or values or trends in a specific operating parameter or condition of interest.
- the analogue calculation portion may comprise a hardware analogue computing device, for instance with an analogue computing circuit suitable for the specific monitoring application in which the operating parameter monitoring device is to be used.
- the analogue computing circuit may be customised for the specific situation in which it is to be used.
- the analogue calculation portion may be configured to compare the measurements of the one or more parameters against predetermined values of the operating parameters that reflect normal operating conditions.
- the predetermined values may be a single value, a range of values (e.g. with an upper and/or lower limit) or the like.
- the measurements may be compared against the predetermined values in order to detect a fault.
- the analogue calculation portion may calculate a change in the measurements of the operating parameters (over any suitable period of time) and/or the rate of change of the measurements of the operating parameters and the change and/or rate of change may be compared against the predetermined values in order to detect a fault.
- the predetermined values may be set in the hardware of the analogue calculation portion.
- the predetermined values may be stored in electronic memory associated with, and accessible to, a control portion of the operating parameter monitoring device.
- the analogue calculation portion may be adapted to receive an electronic control signal via a communication portion of the operating parameter monitoring device against which the measurements received from the one or more sensors may be compared.
- the measurements may be transmitted by the one or more sensors in the form of an analogue or digital signal, and in particular an analogue or digital voltage signal.
- the analogue calculation portion transforms the signal received from the one or more sensors into the output signal message.
- the output signal message may be configured to indicate the presence or absence of a fault.
- the output signal message may be of any suitable form, although in a preferred embodiment of the invention the output signal message may comprise a compressed information signal.
- the compressed information signal may include a relatively small amount of electronic information in the form of data relating to the operating parameters, the sensors and/or the measurements.
- the output signal message may simply indicate the presence of absence of a fault.
- the output signal message may comprise either a‘high’ voltage signal or a‘low’ voltage signal. It is envisaged that the‘high’ voltage signal may represent either the presence or absence of a fault, while the‘low’ voltage signal may represent the other of the presence or absence of a fault.
- ‘high’ voltage signal and‘low’ voltage signal do not necessarily mean that the signals are of a high voltage and a low voltage. Instead, it is envisaged that the‘high’ voltage signal’ will have a higher voltage than the‘low’ voltage signal.
- the operating parameter monitoring device may also comprise a control portion.
- the control portion may be adapted to receive the output signal message from the analogue calculation portion and transmit (or manage the transmission of) the output signal message to the one or more recipients.

- the volume of data contained in the output signal message may be at least two orders of magnitude lower than the volume of data contained in the measurements.
- Digital data if used, must be measured at rates of between 10 and 100 times the frequencies expected in the measured signal to prevent aliasing and/or magnitude loss. It is envisaged that data in the order of megabytes may be received from the sensors and converted into an output signal message comprising information in the order of bytes.
- the invention has specific relevance to accelerometer measurements which include high frequency signal components.
- the reduction in data may be achieved using any suitable analogue circuit technique. This may be achieved by, for instance, designing an analogue circuit to produce mathematical processes required for the analogue signals. It is envisaged that the circuits will therefore provide analogue signal processing to transform the sensor analogue voltage output into a high/low voltage signal to be read by the control portion.
- the present invention will consume relatively low quantities of electrical power and may be relatively low cost in comparison to prior art devices. It is envisaged that the low cost of the present invention may be achieved through both the cost of the components of the operating parameter monitoring device and also ongoing operational costs.
- the control portion may comprise, or be electronically associated with, a communication portion.
- the communication portion may be of any suitable form, although it is envisaged that the communication portion may be adapted to transmit the output signal message to the one or more recipients.
