Ultrasonic Sensor For Object Detection With SAE J1939 Interface
Posted by on
The XX Ultrasonic sensors (formerly Osisense) by Telemechanique Sensors perform contactless object detection. In addition, they provide an SAE J1939 interface, making them suitable for use in mobile machines.
Reliable object detection is feasible regardless of light conditions, the target’s shape, texture, color, or transparency. The sensors can resist harsh environments and operate in diffuse, reflex, and thru-beam modes. The devices are available with IP65, IP67, or IP69K degrees of protection. They can operate at supply voltages from 9 VDC to 32 VDC. Operation temperature ranges from -40 °C to +70 °C. The integral connector and available cabling and fixing accessories simplify the device’s installation.
The sensor line includes ultrasonic sensors (cylindrical or flat format) with discrete solid-state output with adjustable sensing distances of 5 cm to 8m (2" to 25'). Furthermore, the cylindrical ultrasonic sensors for level monitoring allow control of two levels (emptying and filling levels) with sensing distances from 50 cm to 2 m (20" to 7'). Other sensor variants (cylindrical or flat format) are available with analog outputs of 4 mA to 20 mA or 0 V to 10 V. Adjustable sensing distances from 50 cm to 8 m (20" to 25') are available.
The current features of the sensor line include the E2-certification, which considers the immunity to electromagnetic interference, which is vital for the device’s operation in demanding applications such as mobile equipment. Detection of small targets and poorly reflective and curved surfaces is also feasible. Furthermore, with the recently-invented ‘synchronization’ feature, it is possible to reliably detect objects over a large area with minimal risk of cross-talk between multiple sensors, even when the ultrasonic sensors are installed in close proximity. The Ultrasonic XX Software is available for setting up and customizing the sensors. Parameters such as operating mode, window area, hysteresis, and echo options can be adjusted to serve specific applications.
SAE J1939 Starter Kit And Network Simulator
Our J COM.J1939 Starter Kit And Network Simulator is designed to allow the experienced engineer as well as the beginner to experiment with SAE J1939 data communication without the need of connecting to a real-world J1939 network, i.e. a diesel engine. It may sound obvious, but in order to establish a network, you need at least two nodes, and that fact applies especially to CAN/J1939 where the CAN controller will basically shut down after transmitting data without receiving a response. For that reason, our jCOM.J1939 Starter Kit And Network Simulator consists of two J1939 nodes, namely our jCOM.J1939.USB, an SAE J1939 ECU Simulator Board With USB Port.
