2BHBH-95568866The Quantum Dual Band HyperQ Node is an all-in-one single component for seismic sensor applications

Chapter 2 Quantum NODE 15 Chapter 2 Quantum NODE Quantum Node (QN) The Quantum Node is designed to work without the need for radio communication with the Central Recording System. The node acquires GPS signal for timing and communicates locally to the user through Bluetooth Low Energy (BLE) network. The Quantum Node consist of 16GB local data storage, internal battery and integrated vertical 5Hz or 10Hz high-sensitivity phone or a MEMS sensor (Accuseis). The rugged waterproof housing protects the ground station electronics from rough handling of seismic field crews. Features • Compact design and light weight allow easier equipment deployment across challenging terrains and dense vegetation • Rugged watertight casing provides additional protection of ground electronics for extended product life • Bluetooth Low Energy (BLE) technology – delivers communication between the user and equipment to improve field operations involving deployment and equipment status collection with minimal power consumption High-speed USB interface is also included for routine data downloading when connected to the iX Transcriber computer: • Positive Operation LEDs provide instant verification of Node and Sensor Health, Quality of GPS Signal, Battery Voltage • Low power consumption allows up to 50+ days of continuous seismic data recording • Hibernation Mode 16 Hibernation Mode Normally the Node will not be powered on when laying on any side or on upside-down position. Once a node is in upright position, it turns on automatically see: See Node Deployment Typically, the Quantum Node is stored, transported, and carried for deployment in a “Node Carrier” as pictured below. This ensures the Node does not power up (and consume battery) unnecessarily or have false deployments while going to the receiver location. As in the picture below, where a user or shipper handler may mistakenly turn the container on its side. This would result in half the Nodes in “normal operating mode” to be in a “ON” setting and searching for GPS trying to get ready for recording and consuming Battery Hibernation mode is a selection made by the user while the Node is in the Download/Charge rack. On “ hibernate”, see Connectivity A Node set to “Hibernate” will not turn on, no Bluetooth, no GPS and very low battery consumption. Nodes will exit hibernation mode at the time when the unit(s) is docked in a Download and Charge rack. From that point on, unit(s) resume the Quantum's normal operational behaviors Chapter 2 Quantum Node 17 Quantum Node Specifications Quantum Node built in Geophone 18 Quantum Node with external connector This node can be configured (using Quantum Config) to use either the internal built in Geophone or an external geophone such as a Marsh phone. Chapter 2 Quantum Node 19 Quantum Node, internal MEMS Sensor - Accuseis 20 Operation The Quantum Nodes are typically placed at every receiver station. The node turns on automatically after placing it on the ground in upright position. The node LED is flashing orange at the beginning while it runs tests and acquires GPS time fix. Normally after GPS fix is made, the LED starts flashing green (slow) indicating that node is awake and working properly. When LED is flashing red, the node is tilted more than 10° from the vertical position or other error has occurred. The QC Tool can be used to connect to the unit to finish the deployment, perform QC, collect status data or troubleshoot, if required. Quantum Field Deployment, Harvest and QC Tools The QC Tool is used for local communication with the Quantum Nodes (QN). The QC Tool is a rugged Tablet device running the QC Tool software or can be installed on an Android Tablet (OS version 7.0 or greater) supporting BLE (version 4.0 or greater). The QC Tool uses Bluetooth Low Energy (BLE) communication protocol and can quickly acquire QC and status information from the deployed nodes. The QC Tool can also be used to monitor real-time seismic data acquisition by Quantum Nodes in the field. Chapter 2 Quantum Node 21 Node Deployment Before deployment, the nodes should be fully charged and must be pre-configured with survey specific parameters while plugged into docking station and connected to the iX1 Transcriber . The node is off service when laying on any side or on upside-down position. Once node is in upright position, it turns on automatically. Refer to the figure below. INOVA recommends to keep the nodes off service before actual deployment. Depending on the ground condition, there are different scenarios of the node installation. Refer to the figure below. • Optimally, the top of the node should be flushed with the ground. If desired, the node can be buried under a few centimeters of soil. • On the hard surfaces a hole can be drilled to the depth of the spike before installation. • In case of the loose gravel, the shovel can be used to dig a hole which then can be refilled with the same material after node installation. 22 Important Do not use impact tools such as hammers during the node layout. If the nodes have been transported by more than a few hundred kilometers from the last deployment position, it is important to re- acquire the GPS almanac before starting a new project. The nodes must be placed outside with a good sky view. It may take up to 20 minutes to update the GPS satellite almanac and ephemeris data. After setting the node vertically on the ground, it turns on automatically and the LED starts flashing orange while it performs a self-test and acquires a GPS Fix. Once a GPS Fix is acquired, the LED starts flashing green (slow) indicating that node is in the data acquisition mode. Now the node can be accessed by the QC Tool over Bluetooth Low Energy (BLE) network to gather the QC/Status data or troubleshooting, if required. Deep Sleep Mode • Ultra low-power mode • No data acquisition or GPS timing • This mode is automatically initiated when node is tilted more than 30° of upright vertical position Self-Test Mode • Node performs …

The seven antenna types are: • Monopole T-shaped antenna • Monopole L-shaped antenna • Inverted F Antenna – IFA • Microstrip meandered monopole antenna • IFA metal plane antenna • Yagi-Uda antenna • Chip antenna On-board antennas reference design for the STM32WB Series MCUs AN5434 Application note AN5434 - Rev 1 - January 2020 For further information contact your local STMicroelectronics sales office. www.st.com Figure 17. Simulated radiation pattern for the simplified and complete models at 2.45 GHz: (a) φ=0° (XZ plane), (b) φ=90° (YZ plane), (c) Θ=90° (XY plane) 3.5Inverted F antenna - IFA 3.5.1Configuration Numerous research studies are conducted to analyze the Inverted-F antenna such as in [4] where the authors present experimental observations about the IFA performances at the frequency 1.8 GHz for portable handsets. The 3D inverted-F antenna is also explored in the presence of parasitic elements in 1989 by H.Nakano and his colleagues[5], to reveal the behavior of the input impedance and to widen the impedance bandwidth. Similarly, the geometry and dimensions of the proposed inverted F antenna conceived here, are shown in Figure 18. The simplified and complete designs are also investigated here to ensure good accuracy results. This design is compact compared to the previous ones with an overall size of 52 x 30 mm 2 . Additionally, to optimize the location of the radiating element on the small PCB, an L-shaped extension is added to achieve resonance at the desired frequency without increasing the PCB dimensions as presented in Figure 18 (a). Figure 18. Inverted-F antenna configuration: (a) simplified model (b) complete model 3.5.2Simulation results The proposed IFA models are designed also on the FR4 substrate based on dimensions shown in Figure 18. The simulated return loss for the simplified model is shown as a black line, while the complete one is as a dashed red line in Figure 19. A slight shift of the resonance frequency can be observed when the antenna is placed on its real environment. However, a good reflection coefficient is maintained over the ISM range of frequencies. Notice that the resonance associated with the chip PCB is not excited with this compact antenna topology and the matching frequency band is consequently narrower. AN5434 Inverted F antenna - IFA AN5434 - Rev 1 page 13/44 In Figure 20, the simulated input impedance variation within frequency is exposed. An insignificant difference is observed in terms of real and imaginary parts when switching to a complete model. Figure 19. Simulated return loss versus frequency for simple and complete models Figure 20. Simulated input impedance versus frequency for simple and complete models AN5434 Inverted F antenna - IFA AN5434 - Rev 1 page 14/44 Figure 21 illustrates the total efficiency of the IFA antenna against frequency. A decrease of 1.6 % is observed in the case of the complete model compared to the simple one. Figure 22 shows the 2D radiation pattern in terms of gain, in three different planes at 2.45 GHz. Omnidirectional radiation is observed in the plane Θ=90°. Notice that a good agreement is achieved between the complete and simplified models, except the cross-polarization level that increases in the φ=0° and Θ=90°. The asymmetry of the diagram is observable in the φ=0° cut plane due to antenna topology. Figure 21. Simulated efficiency versus frequency for simple and complete models Figure 22. Si…
