PANTOBOT 3D is a fully automated three dimensional pantograph inspection system which allows the network operator to make real time decisions based on the actual condition of the pantograph. It is well known that a damaged pantograph has the potential to tear down the overhead line. This could result in prolonged delays and widespread service disruption. Common examples of pantograph anomalies include chipping, increased wear and cracking of the carbon strips.
PANTOBOT 3D represents a massive change in the image capture, processing and analysis of train pantographs. With conventional 2D technology, subjective assessment could only be achieved in the presence of an expert engineer. However, the arrival of 3D pantograph reconstruction has allowed the machine to automatically undertake quantitative analysis of carbon strips to the nearest millimetre. Machine learning algorithms trend individual pantograph models to predict when the pantograph is approaching the end of its lifespan. This accurate prediction ensures that maintenance schedules are fully optimized.Analysis on Every Axis
PANTOBOT 3D can automatically analyse the degree of carbon wear, chipping and cracking on every axis (X, Y, Z) to the nearest millimetre. This is something that 2D systems are incapable of as they require the expertise of an operator.
It is common for different trains with different pantographs to operate on railway networks. But, by using the power of machine vision, PANTOBOT 3D is able to automatically classify each pantograph model for analysis. This enables the railway operator to programme different alarm thresholds for different types of pantographs.
Predictive maintenance is a key element of asset management. The unique machine learning feature of PANTOBOT 3D allows it to monitor and trend pantograph health and provide the network operator with vital information such as pantograph failure.
PANTOBOT 3D takes one high definition image of the pan head at any speed up to 300km/h with no loss of image resolution (0.4mm). Conventional 2D and 3D systems take multiple shots of the pan head for analysis. This antiquated technology considerably reduces image resolution as the train speed increases, making it more difficult to identify cracking and chipping at an advanced stage.
Pantograph uplift is a highly important measurement as it lets the operator know whether the pantograph is applying too much or too little force on the contact wire. This is a standard machine vision feature in the PANTOBOT 3D which means that no additional modules or measuring devices are required to obtain this information. Weather station modules can be added to determine wind speed and direction.
A web based interface allows the user to access PANTOBOT 3D via any secure device connected to the internet. Our intuitive platform gives the user the ability to define the operating limits of each pantograph model and set individual alarm thresholds. Pantograph images can also be viewed for further analysis.
PANTOBOT 3D is a perfectly designed modular system that is easy to install and requires minimal maintenance. The system can be installed on vertical poles either side of the running railway or fixed to an overhead structure. One distinct advantage of a vertical pole installation is that the railway can still operate normally and no possessions or isolations are required.
