Hesai: PandarXT ─ The Next Generation of LiDAR
Hesai Technology, the global leader in 3D-sensors (LiDAR), has released a new 32-channel mid-range LiDAR, PandarXT; it features a new system architecture which integrates Hesai’s self-developed, industry-leading LiDAR ASICs. The PandarXT is a cost-effective solution designed for multiple applications, including autonomous logistics, robotics, surveying, security, mapping, and low-to-medium-speed driving. The perfect solution for manufacturers and supply chain networks that are looking to evolve into a tech-enhanced utopia.
What is LiDAR?
LiDAR (Light Detection and Ranging) is a remote sensing method that uses light to precisely measure distance. A LiDar sensor rapidly sends out pulses of laser light, which are reflected off surrounding objects. By measuring the time it takes the light to travel to each object and back, the exact distance can be calculated. A LiDAR sends out hundreds of thousands of pulses per second; these measurements are then collected and used to create a £D model of the environment, called a point cloud.
“LiDARs can be used for a number of applications, including autonomous driving (robotaxis, passenger cars, trucking, logistics vehicles, etc.), mapping, smart city/V2X, security, and robotics.”
PandarXT ─ Cutting Edge Sensors
In many situations, sensors do not require ultra-high resolution and ultra-long ranging capabilities; instead, they demand a very precise balance between performance, reliability, and cost. PandarXT was developed with those three factors in mind. Hesai put “extensive R&D work and testing have gone into designing specialised LiDAR ASICs that integrate the functions of dozens of circuit boards.”
The good news for manufacturers is that the new transceiver system streamlines multiple complex optical assembly and adjustment processes into just one process, which reduces the cost and improves performance, reliability, and manufacturing scalability.
“The new system architecture, based on Hesai's self-developed LiDAR ASICs, delivers additional performance enhancements. PandarXT has a minimum range of zero and outputs valid point cloud even when an object directly touches the sensor's enclosure. It also has millimetre-level ranging accuracy and superb precision. Furthermore, its improved reflectivity accuracy and greater dynamic range enable accurate and consistent detection of retroreflectors, low-reflectivity targets, and object boundaries with sudden changes in reflectivity. Consistent with every LiDAR in Hesai's Pandar series, PandarXT has undergone and passed stringent reliability testing to ensure robustness and reliability in any operational environment.”
PandarXT marks a breakthrough in LiDAR system design and its combination of performance, reliability, manufacturing scalability, and cost-effectiveness makes it the optimal choice for LiDAR-powered applications.
Siemens: Providing the First Industrial 5G Router
Across a number of industry sectors, there’s a growing need for both local wireless connectivity and remote access to machines and plants. In both of these cases, communication is, more often than not, over a long distance. Public wireless data networks can be used to enable this connectivity, both nationally and internationally, which makes the new 5G network mainframe an absolutely vital element of remote access and remote servicing solutions as we move into the interconnected age.
Siemens Enables 5G IIoT
The eagerly awaited Scalance MUM856-1, Siemens’ very first industrial 5G router, is officially available to organisations. The device has the ability to connect all local industrial applications to the public 5G, 4G (LTE), and 3G (UMTS) mobile wireless networks ─ allowing companies to embrace the long-awaited Industrial Internet of Things (IIoT).
The router can be used to remotely monitor and service plants, machines, as well as control elements and other industrial devices via a public 5G network ─ flexibly and with high data rates. Something that has been in incredibly high demand after being teased by the leading network providers for years.
Scalance MUM856-1 at a Glance
- Scalance MUM856-1 connects local industrial applications to public 5G, 4G, and 3G mobile wireless networks
- The router supports future-oriented applications such as remote access via public 5G networks or the connection of mobile devices such as automated guided vehicles in industry
- A robust version in IP65 housing for use outside the control cabinet
- Prototypes of Siemens 5G infrastructure for private networks already in use at several sites
“To ensure the powerful connection of Ethernet-based subnetworks and automation devices, the Scalance MUM856-1 supports Release 15 of the 5G standard. The device offers high bandwidths of up to 1000 Mbps for the downlink and up to 500 Mbps for the uplink – providing high data rates for data-intensive applications such as the remote implementation of firmware updates. Thanks to IPv6 support, the devices can also be implemented in modern communication networks.
Various security functions are included to monitor data traffic and protect against unauthorised access: for example, an integrated firewall and authentication of communication devices and encryption of data transmission via VPN. If there is no available 5G network, the device switches automatically to 4G or 3G networks. The first release version of the router has an EU radio license; other versions with different licenses are in preparation. With the Sinema Remote Connect management platform for VPN connections, users can access remote plants or machines easily and securely – even if they are integrated in other networks. The software also offers easy management and autoconfiguration of the devices,” Siemens said.
Preparing for a 5G-oriented Future
Siemens has announced that the new router can also be integrated into private 5G networks. This means that the Scalance MUM856-1 is, essentially, future-proofed when it comes to 5G adaptability; it supports future-oriented applications, including ‘mobile robots in manufacturing, autonomous vehicles in logistics or augmented reality applications for service technicians.’
And, for use on sites where conditions are a little harsher, Siemens has given the router robust IP65 housing ─ it’s “dust tight”, waterproof, and immersion-proofed.
