Definitions

  • the present invention relates to a gauge reading device according to the preamble of claim 1 and a system comprising such a device.
  • a gauge can typically include a measurement section and a display section.
  • a measurement section can measure some condition (e.g., pressure, temperature, rate, position, time, concentration, density, force, intensity, physical dimension, velocity, acceleration, or other quantities, to name but a few) .
  • a display section can display the measured value.
  • Many gauges, typically analog gauges, include a display intended for human eyes.
  • a gauge can represent a measurement value with a deflected needle (or arrow) , a variable bar size, or other geometric shape that varies according to a measured value.
  • Modern monitor and control systems are typically designed with a centralized monitoring system. However, because some gauges are designed for visual examination, they typically do not output an electrical signal and thus cannot be easily integrated with a central control system.
  • WO 2008/079344 A2 shows a gauge reading system, comprising a parameter store that stores parameter data in digital form for at least one gauge; image processing circuit coupled to receive image data from an image sensor physically attached to at least one gauge, the image processing circuit analyzing the image data to generate image data points corresponding to the gauge image, and generating a gauge measurement value from the image data points and the parameter data; a transmitting circuit that transmits the gauge measurement value to a location remote from the gauge; and control circuit for activating at the image processing circuit and coupling the gauge measurement value to the transmitting circuit.
  • a drawback to such an approach can be that access to the site network is needed for every single reading device leading to significant installation work and also security concerns.
  • the present inventions provides for a low-cost gauge reading device which can easily be retrofitted to any gauges which are installed in facilities, e.g. on cylinders, packs, tanks etc.
  • This device requires no changes to the existing systems (e.g. no safety relevant changes to the valves) but may be simply clipped to existing gauges.
  • the gauge reading device reads and stores the gauge measurement value and provides it for being wirelessly read out. This allows for the gauge measurement value being read out wirelessly by a reading means, e.g. a handheld data collecting device, especially a handheld computing device such as a smart phone or a tablet pc, when needed, without additional hubs or network fees.
  • the device is in no need of additional installation of network hubs and doesn’t need to be integrated into local networks.
  • the reading means can be configured to transmit the read out data to a remote system where the data can be processed.
  • Figure 1 is a schematic diagram of a preferred embodiment of a gauge reading device according to the invention.
  • the gauge reading device 100 includes a housing 110, which is preferably made from metal, such as aluminium, or plastics, and attaching means 111 being configured for attaching the housing 110 to a gauge 1.
  • the housing may be explosion proof (especially according to ATEX Directive 2014/34/EU) .
  • the attaching means 111 may include snap hooks.
  • the attaching means 111 are configured such that it fits to gauges of different type and size.
  • the attaching means 111 may comprise elastic bands.
  • the gauge 1 can be an analogue gauge for measuring pressure and displaying the measured value with a deflected needle.
  • the housing 110 can have a transparent window 113 or an open front side to maintain the possibility of the gauge being viewed by a person.
  • the gauge reading device 100 further comprises imaging means being here configured as a camera 120.
  • the camera 120 is configured for imaging the gauge 1 and generating an image thereof.
  • the camera 120 may be an infrared camera.
  • the camera 120 is connected with processing means 130, e.g. an integrated circuit (IC) such as an ASIC or microcontroller, which is in the shown embodiment located in a cabinet 112, which is part of the housing 110. In case the housing is big enough, the cabinet 112 can be omitted and the elements can be located directly inside the cylindrical housing.
  • the IC 130 is configured for processing the image of the gauge 1 for determining a gauge measurement value.
  • the gauge reading device is equipped with lighting means being configured here as one or more LEDs 150, e.g. white or infrared LEDs.
  • the gauge reading device 100 further comprises storing means being configured for storing the determined gauge measurement value, and one-way-transmitting means being configured for providing the stored gauge measurement value to be read out wirelessly by a reading means, both being configured here as a Bluetooth low energy beacon 140.
  • the Bluetooth low energy beacon 140 and thus the gauge measurement value stored therein by the IC 130 can be read out by a smart phone 200 as reading means.
  • narrowband technology or GSM may be used for transmission.
  • the gauge reading device 100 further comprises a battery 160 for powering the device.
  • the battery 160 is replaceable and chargeable, especially via a charging interface 170.
  • the interface 170 can be configured for charging the battery 160 and for communicating with the IC 130, e.g. for writing/programming and/or reading.
  • a suitable standard for such an interface is USB standard.
  • the IC 130 is preferably programmed with gauge data which can be used for determining the gauge measurement value based on the gauge image.
  • the interface 170 may be omitted or may be located inside the housing.
  • the gauge reading device 100 further comprises in the shown embodiment positioning means 180 in the form e.g. of a GPS device or Wi-Fi sniffing unit configured for determining the position of the device.
  • positioning means 180 in the form e.g. of a GPS device or Wi-Fi sniffing unit configured for determining the position of the device.
  • the IC 130 is advantageously configured for storing the determined position into the Bluetooth low energy beacon 140, and the Bluetooth low energy beacon 140 is configured for providing the stored position to be read out wirelessly by the reading means.
  • the gauge reading device 100 is preferably configured such that the energy consumption is very low and the lifetime of the battery without charging is very high. This can be accomplished by the following preferred procedure.
  • the gauge reading device 100 is automatically powered on.
  • the IC 130 can be configured to wake up from a low energy consumption state (e.g. SLEEP, STANDBY, IDLE) by timing means. Then, IC 130 powers on the further components, i.e. camera and illumination and takes a photo of the gauge using the camera 120.
  • a low energy consumption state e.g. SLEEP, STANDBY, IDLE
  • IC 130 interprets the photo to a gauge measurement value and re-programs the beacon 140 with the new gauge measurement value (and optionally the position of the device) .
  • IC 130 powers off illumination and camera immediately after taking the photo. Finally, IC 130 goes into the low energy consumption mode and waits for the next wake-up.
  • Any person with a smartphone 200 as reading device passing by with a corresponding app can pick up the beacon information (gauge measurement value and position) , display the information of all read-out devices and transmit this information to a remote server for further processing.
  • the beacon information gauge measurement value and position
