Description

The present invention relates to a measurement data acquisition system having at least one detection unit, at least one master unit and at least one data center, wherein the detection unit is connectable to a measuring device, and the detection unit is in contact with a master unit, and a method for operating a measurement data acquisition system.

Measuring devices can be found for a variety of purposes and in various forms, such as counter devices in the form of electricity, water, gas, heat meters or counters for escalator kilometer and operating hours meter.

Such measuring devices must be read regularly in order, for example, to check the meter readings and to document these for billing purposes or for the determination of maintenance intervals. These manual readings mean a high expenditure on technical personnel and travel costs as well as counter devices in households time expenditure for the consumer, who must be at home to these read-off times. In addition, manual readings result in problems from erroneous readings and in the absence of the consumer whose meter is to be read.

Simplifying the traditional system of manual meter reading provides the ability to automatically read these counters.

Mobile readers are known. For example, describes the DE 10 2008 042 296 A1 a meter reading system provided with a mobile reading device. Each meter is provided with a reading device and connected to a measured value recorder. The mobile reader sends via microwave or SMS a control signal to the sensor that activates the reader to recognize the measured values. However, this reader is only suitable for certain number counter types.

In the US Pat. No. 6,975,862 B1 An apparatus and method for wireless remote measurement from provider to consumer is described. However, this wireless connection is made over the telephone, so that a foreign telephone network must be present and thus incur additional costs.

A system and method for wireless reading of counters is also used in the EP 2 261 608 A1 described. However, the use of magnetic reading techniques may interfere with the accuracy of the reading.

Despite the advantages of automatic meter reading, a manual reading, e.g. B. for control purposes, continue to be possible. Often, units for automatically reading the meters obscure the counter means so as to prevent manual reading of the values. EP 1 946 483 B1 describes a meter detection system which is equipped with a viewing window and by the use of semi-transparent mirrors or folding mirrors, a manual reading of the meter continues to allow and avoids disturbing light reflections. For this purpose, polarized filters are used. Through the use of color filters or polarized filters, however, it may happen that certain colors, such as red numbers on the number of rollers, can not be detected by the image sensor.

Previously, a digital pulse interface (reed contact) was required for the automated reading of counters, whereby the previous reading technique using reed contacts made manual reading more difficult. In addition, digitally read values of metering devices are often not recognized by media providers, as there may often be large deviations from the real value due to spurious pulses or influence from induction and magnetism.

The object of the present invention was therefore to read automatically with a single system all types of meters regardless of their design and the presence of a digital pulse interface or its purpose. This reading system should be retrofittable to existing measuring devices as well as be used with new measuring devices and be inexpensive to implement. Existing measuring instruments in niche industries, such as B. the escalator kilometer measurement should also be detectable without special reading systems must be developed. A manual reading should still be possible. The new automatic reading is intended to circumvent these problems and also create simple and cost-effective accounting systems.

The object is achieved by a method for operating a measurement data acquisition system, wherein at least the following steps are implemented:

• - Data acquisition of a measuring device with a detection unit
• - Provide the data with a timestamp
• - Transmission of measurement data of a detection unit to a master unit
• - If necessary, conversion of an image file into a number format
• - If necessary, compress the data
• - Save the data
• - Transmission of measurement data to a data center
• - Evaluation of the data in the data center

For the purposes of the present invention, the term "measuring device" encompasses all measuring devices which count and / or display a type of quantity, such as electricity, water, gas, heat meters or counters for escalator kilometer recording and operating hours meters. These meters have a numerical mechanical or digital display. It is also possible to detect and recognize alphanumeric images, as they are present, for example, on machine displays. Readable data is preferably acquired opto-electronically. Sensors such as temperature sensors, pressure gauges, moisture meters, brightness meters, heat meters or sound meters are also included in the term. The recording of levels or other readable areas in monitored processes, such as mailboxes or silos, is not excluded.

Preferably, the data acquired by a detection unit is provided with a time stamp, for example in the format YYYYMMDDTSMMSS. The collected data is then sent to a master unit. Detecting unit and master unit can be located either in a housing or in different, separate housings. If several detection units are put into operation in one system, good reception to the individual detection units can be ensured by an independent placement of the master unit. Preferably, the detection units can also function as a kind of repeater, so that a detection unit which is outside the range of the master unit can still communicate with the master unit and vice versa.

For sending the image data and / or the measurement data of the connected sensors, standardized radio transmission technology is preferably used. In the master unit, the optically acquired image is converted by means of a local microprocessor and firmware into a database-capable format, for example ASCII code. By combining the image and the data entry date, the read data is recognized by media providers. The conversion can also be done via a server. These methods can save costs for a GSM transmission. Conversion is done by handwriting recognition, such as OCR software. The data from sensors are transmitted directly to the detection unit and sent from there to the master unit for storage and further evaluation. Then, the data is compressed to ensure better, faster, and thus more energy efficient, transmission to a data center, and stored.

The data contained in the memory of the master unit are preferably bundled and interval-controlled and / or sent by exceeding a threshold and / or manual triggering, for example via a portal or SMS, by GSM / GPRS or other common transmission methods to a data center for further evaluation. After a successful transfer to a data center, the data in the master unit can be deleted.

• – Überprüfen der Daten auf Vollständigkeit und Plausibilität
• – Überprüfen der Daten und Abgleich mit älteren Zählerstanddaten und/oder Sensordaten
• – Alarmierungsfunktion bei Grenzwertüberschreitung und/oder Grenzwertunterschreitung der Daten

According to an advantageous embodiment of the method according to the invention, the evaluation of the data in the data center comprises at least the following steps:

• - Check the data for completeness and plausibility
• - Check the data and compare with older meter reading data and / or sensor data
• - Alerting function when the limit value is exceeded and / or the value falls below the limit

The method according to the invention can also be used to make comparisons with detected frames and fixed bit patterns, such as images of error codes of displays. This is z. For example, it is possible to enable consumption monitoring to monitor industrial machine displays. As soon as a stored reference image matches the value read, an optical or acoustic signal can be triggered. The alarming function can preferably be triggered directly on site by a signal generator connected to the master unit or by the portal which is informed via the web interface.

According to a further aspect of the present invention, data is transferable from the detection unit to the master unit via cable and / or wireless, and the transmission of measurement data to a data center preferably takes place wirelessly via a digital web interface and / or LAN and / or M-BUS. In this case, the term "web interface" encompasses data sent by the master unit, preferably via GPRS, to a server in a defined and standardized protocol. The wireless transmission can be done via radio or network, such as LAN, M-BUS.

It is further preferred that the data center includes a billing function and / or a raw material purchase function and / or a tariff change function and / or a status mode check function and / or other interfaces.

The received data are preferably stored in a data center on a server in a database and analyzed or further processed. A customer can access his personal data in the internet-based database by logging into the portal.

Automated monitoring applications of the measured data and the systems give the user many possible applications. In addition to the provision of the values in a portal, further advantageous functions, such as automatic billing with energy and media providers, alerting functions, price comparison function (tariffs), analysis function with action recommendations, forecast function, cross-selling and advertising placement as well as other interfaces, for example for social networks, affiliate Partners, third-party database archives, own platforms from other service providers and institutions, mobile services.

In combination with GSM modules, web interfaces can also be created, enabling customers to access their measurement data at any time, regardless of location. Thus, in addition to automatic monitoring algorithms, automated billing processes with energy and media suppliers are possible, which enables a high cost-saving potential. In addition, web interfaces to mobile services are beneficial.

The status mode check function can be used to query values such as reception strength, individual readings, battery capacity or firmware / hardware version.

The inventive method further allows the data to be encrypted in the master unit. By this advantageous embodiment manipulations should be avoided.

In a preferred embodiment of the method according to the invention, the firm software is updated via the data center.

• - an evaluation module

The measurement data acquisition system according to the invention is easy to install. Replacement of the existing measuring device is not necessary thereby saving considerable costs. The technique required to apply the method is cost-effective, so that automated data acquisition systems are also suitable for the private sector. A detection unit is assigned to at least one measuring device. The assignment of multiple instruments of the same type and purpose and of the type and purpose of different measuring instruments to a detection unit is not excluded.

Preferably, the detection unit can be arbitrarily attached to a measuring device. If the meter has a numerical display, this is recorded opto-electronically. It does not matter in which orientation this display is captured in the form of an image by the camera. The image can later be rotated by the corresponding software.

The reading is preferably carried out by optical detection of the meter reading without interfering with the measuring method of the meter. The detection unit of the measurement data acquisition system according to the invention contains at least one camera module, which focuses and picks up the numeric field of a measuring device via an optical means, for example a mirror or a prism. Since the counter device is mostly in the dark, the counter field is illuminated directly or indirectly via a light source. Due to the arrangement of the optical means disturbing reflections and glare, which can be caused for example by external light sources, and back reflections are avoided.

In particular, the recorded video stream is reduced in the microprocessor on the board to only one frame and converted as an image file and aligned readable. The file name will be timestamped. The converted image or frame can be transmitted either via cable or radio to the master unit. With radio are generally includes all types of radio such as ISM, WLAN, Bluetooth, etc.

In the master unit, in particular, the image data are converted via a recognition software, firmware based on microprocessor, into a database-capable text format in order to keep the amount of data in the GSM / GPRS transmission as low as possible and thus to save energy and transmission costs. Conversion of the image data into a text format as well as a subsequent compression of the data is an advantage since the device has to operate in isolated locations for several years even without an external power supply. The image data and text formats are buffered until a successful transfer to a data center has occurred.

In one embodiment of the measurement data acquisition system according to the invention, it is preferred that the detection unit is provided with at least one viewing window and the measuring device is manually readable.

In a preferred embodiment of the measurement data acquisition system according to the invention, the power supply of the master unit and the detection unit is ensured via battery and / or power supply.

It is furthermore preferred that the measuring device values are recorded by the detection unit in an interval-controlled and time-controlled manner and provided with a time stamp. The use of a timestamp in the format YYYYMMDDDSMMSS allows an exact time allocation of the captured image.

In addition to automated readings, all measuring meters can also carry out interval-controlled monitoring, in which warning messages and alarms can be triggered if limits are exceeded.

In one embodiment of the measurement data acquisition system according to the invention, further detection units can be connected to a detection unit and / or sensors can be connected to a detection unit and / or can be controlled via SMS and / or a position sensor can be connected to a detection unit. By equipping the detection devices with position sensors can. Manipulation attempts are documented or blocked the device.

In a further preferred embodiment of the measurement data acquisition system according to the invention, the detection unit can detect fill levels through a second camera module. With this embodiment, fill levels and / or distance measurements can preferably be detected by means of stereoscopy and thus monitored.

Preferably, the data is transmitted from the detection unit to the master unit via cable and / or wireless and the transmission of measurement data to a data center is wireless via a digital web interface and / or LAN and / or M-BUS. In this case, the term "web interface" encompasses data sent by the master unit, preferably via GPRS, to a server in a defined and standardized protocol.

It is further preferred that the master unit has a GSM module and a SIM card and the SIM card is exchangeable. Due to this advantageous embodiment, no foreign telephone network must be available for reading. GPRS and the own SIM card thus create an autonomous system. The detection unit can be provided with a GSM module or retrofitted, for example via a USB stick.

In a further preferred embodiment of the measurement data acquisition system according to the invention, the master unit has an encryption module for encrypting the generated data and / or an alarm transmission module and / or a compression module for data compression and / or a position sensor. Preferably, the data in the master unit can be checked for overshooting or undershooting of limit values even before it is sent to the data center. This allows the alarm module to be activated immediately before sending the data. Preferably, the alarm module of the master unit is a controllable by a microprocessor relay, which can deliver optional signals when exceeding or falling below of limits.

It is further object of the measurement data acquisition system according to the invention that a verification module is present in the data center to manually and / or by SMS and / or via the Internet query a status mode report. Using the validation module, a status report can be manually requested from the master unit via the web interface.

The status mode check function can be used to query values such as reception strength, individual readings, battery capacity or firmware / hardware version.

Further advantages also result from the computer program according to the invention with program code for carrying out all method steps when the program is executed in a computer.

Another aspect of the present invention is a data carrier on which the computer program according to the invention is stored.

The present invention will be explained in more detail with reference to the following figures.

1 shows a schematic overview of the most important stages of the measurement data acquisition system according to the invention 1 , In each case a detection unit 3 a counter 2 assigned. The individual detection devices are via cables 4 connected with each other. In this case, at least two detection units can be connected to another. If a meter is already equipped with a digital interface, the acquisition unit should acquire, store and transfer the values via an analogue input. The interfaces of the counters provide an incremental pulse which corresponds to a certain value and must be added to the previous value. The sum of the pulses within one hour results in the consumption per hour. Furthermore, sensors can 29 For example, temperature sensor, pressure gauge, humidity meter, brightness meter, heat meter or sound meter, via cable 28 be connected to a detection unit.

In this embodiment, detection unit and master unit are in different, separate housings. At least one detection unit is via a cable 5 with a master unit 6 connected, via which the determined data to the master unit 6 be transmitted. In the master unit 6 The data of the detection unit are converted into database-evaluable characters, which applies in particular to captured images, and can also be added there. This is particularly important for composite meters with a small and a large quantity meter. Sensors connected to the detection unit first deliver their values to the detection unit and are then sent to the master unit for storage and further evaluation. Preferably, an image optoelectronically acquired by a detection unit, and / or a captured image sequence and / or a detected frame and / or parts thereof, any measuring device or the data of a sensor with a time stamp in the format JJJJMMTTSSMMSS detected.

In 3 and 4 the schematic structure of a detection device 3 shown in frontal view, with a meter, here a counter, 2 connected is. The registration unit 3 is with a front window 10 and a rear window 20 provided so that the numeric field 11 of the meter 2 also manually readable. The detection of the numeric field 11 via a focusable camera module 12 with the widest possible wide-angle lens. The distance between the camera module 12 and number field 11 of the meter 2 is kept as large as possible in order to obtain an undistorted image of the digits and the number field 11 also not by the camera module 12 to cover up. This is a prism or mirror technique 13 applied, so that the recorded counter window image is deflected by approximately 45 °. However, other optical methods are possible. The optical means 13 is preferably located behind or in front of the numeric field of the counter and is arranged so that light of the internal light source 14 is reflected at an acute angle. As a result, no disturbing glare, which disturb the quality of image capture.

In order to obtain a high quality image, the detection unit has at least one internal light source 14 present, for example LEDs. There is also a battery 15 as power source available, an external antenna 16 , as well as a circuit board 17 and connections 18 , The connections 18 may be for the master unit and / or other wired detection units and / or sensors and / or for network operation and / or for other modules such as a GSM module and / or for an external antenna.

5 shows a schematic structure of a detection device of another embodiment in side view. The illumination is in this embodiment by an optical waveguide 19 (lit with LED) ensures which outside of the housing between the meter 2 and the detection unit 3 is appropriate. The light does not fall directly on the mirror 13 because the incident angle of the illuminant is too acute, thus avoiding the risk of glare or reflection.

6 shows a schematic structure of a detection device in a further embodiment in side view. In this embodiment is only a rear window 20 necessary. An optical fiber 19 gets behind a mirror 13 appropriate. Thus, no direct rays can get into the camera. In addition, the optical waveguide acts like a diffuser, which prevents the direct irradiation of the LEDs, and thus no points of light can arise. In addition, the light rays hit the numerals of the counter at an acute angle 11 so that the reflective beams are reflected by the number roller away from the detector. In this variant, a transparent dust cap can be used to foul the numeric field 11 to avoid.

In the 7 to 10 Different positions of a mirror are shown. The registration unit 3 is shown only schematically.

7 shows an embodiment in which the mirror 13 in the angle 31 of about 80 ° orthogonal to the numerals of the counter 11 is aligned. To the whole counter window 11 to capture, the capture unit as well as the mirror 13 above the counter window 11 with the lower viewing window 20 to be placed. Because the mirror is the numbers 11 not obscured, no semi-transparent mirror is needed, but a second viewing window 10 ,

In 8th becomes the mirror 13 in the angle 31 from about 45 ° to the numerals of the counter 11 aligned. To the whole counter window 11 to capture, the capture unit as well as the mirror 13 directly above the meter window 11 with the lower viewing window 20 to be placed. Because the mirror 13 inside the registration unit the view of the numbers 11 obscured by the counter, a semi-transparent mirror would be needed. Is the distance between the acquisition device and the digits of the meter 11 big enough, like in 9 represented, so can through the viewing window 10 Looking past the mirror and a semi-transparent mirror is not necessary.

10 shows a further embodiment in which the mirror 13 in the angle 31 of approximately 20 ° orthogonal to the numerals of the counter 11 is aligned and almost completely below the numbers 11 is placed. This is by the viewer 30 an almost straight view of the numeric window possible. A transparent dust cap can prevent soiling and further enable manual reading.

11 shows an embodiment of a detection unit for level monitoring of a pellet silo. This detection unit is equipped with a first image sensor 21 and a second image sensor 22 fitted. Using the detection area of the first image sensor 23 and the detection range of the second image sensor 24 becomes a stereoscopic image of the pellets 26 generated, which continuously from a screw conveyor 27 be transported on a chute construction in the silo. Because the distance between the two image sensors 22 and 23 is known, as well as their angle 25 the lenses, a distance calculation can be done. Software (server side or microprocessor side) defines fixed measuring points. These measuring points result in a three-dimensional plane in space. By subtracting the known volume of the room (maximum filling height) with the calculated level of the pellets results in the current level of the pellets.

With this embodiment, fill levels and / or distance measurements can preferably be detected by means of stereoscopy and thus monitored. It is also possible, for example, to monitor mailboxes with the present invention. For this purpose, the individual mailboxes can preferably be equipped with a reflector and a number, which is set up in each mailbox. Each mailbox can be assigned a specific number. The number of reflectors is not absolutely necessary because the position of the reflector can already be assigned to a specific area. However, the detection of the number in the assignment may also be advantageous. If post is in a mailbox, the reflector is obscured with the specific number. The area with the mailboxes is monitored by the detection unit according to the invention. If the reflector of a particular mailbox is hidden, this information is passed on to the master unit via the corresponding image and the information is sent to the data center. The data center can preferably inform the user about common formats such as e-mail, SMS, smartphone app or tablet PC app that he has been mailed.
