Description

 Method and device for transmitting data

The invention relates to a method for transmitting data with a mobile radio unit via a mobile radio network, the on entity being detected in an aircraft and the transmission of the data being deactivated via the mobile radio network as a function of detection of the presence in an aircraft.

Likewise, the invention relates to a device for transmitting data with a mobile radio unit for transmitting the data via a mobile network, a device for detecting the presence in an aircraft, a device for deactivating the mobile radio unit in dependence on the detection of presence in an aircraft and a power supply.

In addition to call data, countless data is transmitted for various purposes via mobile networks. For example, position data can be transmitted via mobile radio networks and information on the current position of certain objects can be made available, for example, to be able to check in the logistics area where a particular object is currently located.

Due to common aviation safety regulations, such as the International Air Transport Association (IATA), it is necessary to disable mobile units during takeoff, flight and landing until the engines are shut down. For mobile phones owners are prompted by appropriate announcements before the start of the shutdown of the devices or the switching of the devices in a flight mode in which the transmitter unit is disabled. For other devices that automatically transmit data over cellular networks, such as devices for tracking the path of a shipment in the logistics area, it is necessary to manually disable the device before the flight or to provide automatic deactivation.

For example, EP 2 020 754 A1 describes a device for position control of an object, which detects the presence in an aircraft and the data transmission in dependence deactivated in a plane. The presence in an aircraft is determined by corresponding sensors, for example air pressure sensors, motion sensors, vibration sensors, ultrasonic sensors or the like. Many such parameters are unsuitable for reliable detection of presence in an aircraft. In the case of air pressure, the fluctuations in air pressure are particularly large as a function of the height of the respective airport, so that reliable detection of the presence in an aircraft can take place only at relatively high altitudes and thus deactivation of the device during takeoff can not be carried out automatically. Even when the acceleration is detected, the presence in an aircraft can only be detected during takeoff and thus exactly in the critical phase. Also, the de described in the above document tektion the vibrations of the 'engines is relatively unreliable, and allows detection of the presence in a plane only at a relatively late stage, for instance only during startup.

US 2003/0006900 A1 describes a device for the transmission of data, wherein the presence in an aircraft via the power signal of the aircraft takes place at 400 Hz. The disadvantage here is that the antennas are designed to detect the signal is relatively large and beyond such signals do not penetrate into the transport container formed of metal. Therefore, the device can be mounted only on the outside of such transport containers.

WO 2004/063766 Al describes a tracking device, which is also designed with a device for detecting signals with a frequency of 400 Hz.

The object of the present invention is to provide an above-mentioned method and an above-mentioned device for data transmission, which can be reliably deactivated in the event of presence in an aircraft and thus meet the current safety regulations in international air traffic. The method and the device should be as simple and therefore inexpensive to carry out or

be made to ensure a wide application can be. Disadvantages of known methods or devices should be avoided or reduced.

The object of the invention is achieved by an above-mentioned method in which the presence in an aircraft is detected by measuring an SSR (Secondary Surveillance Radar) radar signal originating from the aircraft with a carrier frequency of 1090 MHz and in the case of detecting the radar signal Mobile transmission is disabled when the detected radar signal exceeds a predetermined amplitude over a predetermined period of time, and the mobile transmission is activated again when the detected radar signal falls below a predetermined amplitude over a predetermined period of time.

As a radar signal to be detected, the SSR (Secondary Surveillance Radar) radar signal of an aircraft with a carrier frequency of 1090 MHz is particularly suitable, since this signal is sent out at startup of the aircraft sufficiently long before take-off and is very strong and thus by very small Receiver can be included. The SSR signal is established in aviation technology and serves to clearly detect the position and identity of an aircraft. For this purpose, a transponder of each aircraft sends a modulated signal with a carrier frequency of 1090 MHz, which is detected by the respective ground station.

To improve the correct detection of the presence in an aircraft, the deactivation and activation of the mobile radio transmission is performed when the detected radar signal exceeds or falls below a predetermined amplitude over a predetermined period of time. By a suitable choice of the amplitude and time span, a reliable and reliable detection of the presence in an aircraft can be achieved. The choice of the amplitude and time span for the activation of the mobile radio transmission can be equated with the amplitude and time span as shutdown criterion. Upon fulfillment of the criteria, the mobile radio unit can be reactivated when the aircraft has reached the parking position and the engines have been switched off. Thus, the mobile radio transmission can be made again and, for example, a mobile phone can be reused. the or corresponding data, such as position data, are transmitted again via the mobile network.

In order to avoid a disruption of the method by other aircraft than that in which the mobile unit is located, the above-mentioned predetermined amplitude of the radar signal is selected to be high, so that only the signal of the own aircraft, in which the mobile unit is located, and which Usually has the largest amplitude, leading to automatic deactivation of the mobile unit. The detection of the radar signal is relatively easy to carry out and allows a particularly reliable detection of presence in an aircraft and timely deactivation of the mobile unit. The method can be used for a wide variety of applications, for example, an application in mobile phones is conceivable, so that an automatic shutdown of the mobile unit before the start of an aircraft can be performed. This avoids security risks due to accidentally or deliberately forgotten shutdowns of mobile devices.

The radar signal is preferably detected at periodic intervals. Detection at periodic intervals can reduce energy requirements and extend the life of a device performing the process accordingly. The time intervals are suitably adapted to the respective applications and can range from a few milliseconds to seconds or minutes.

If position data are to be transmitted via the mobile radio network, these can be determined via the mobile radio network itself or also the GPS (Global Positioning System).

If other parameters, such as acceleration, are measured and taken into account when deciding to deactivate and activate the mobile radio transmission, the reliability of the deactivation and activation of the mobile radio transmission can be further increased. For detecting accelerations, in particular angular accelerations, are particularly suitable

gyroscopic sensors, which are particularly small and inexpensive available. By using a preferably three-axis gyroskopischen sensor can be detected by the slightest movements of the airplane and be involved in the decision of deactivation or activation of the mobile transmission.

It is advantageous, furthermore, if the state of a Spannungsver supply detected and at least the undershooting of a predetermined voltage is displayed. Thus, it can be timely ensured that the power supply is replaced and the process can be reliably continued.

In order to enable an unambiguous assignment of the data transmitted via the mobile radio network, the data can be transmitted together with a unique identifier via the mobile radio network. This unique identifier can be formed, for example, by the so-called IMSI (International Mobile Subscriber Identity) of the mobile radio unit.

A further increase in the reliability of detection of presence in an aircraft, can be done in addition to the SSR (Secondary Surveillance Radar) radar signal with a carrier frequency of 1090 MHz detects a signal with a carrier frequency of 1030 MHz and for the decision of Deak activation and activation of mobile communications. Signals with a carrier frequency of 1030 MHz are usually emitted by the ground radar and thus can be used for the Be mood of the relative position relative to the antennas of the ground radar. In this way, for example, it can be distinguished whether the device is placed in a warehouse adjacent to the airport and not on board an aircraft. The information of the signal form of the 1030 MHz signal thus serves as another input for the decision of deactivation and activation of the mobile radio transmission.

A further improvement in the reliability of detection of presence in an aircraft can be achieved by detecting the local arrangement of mobile radio transmitters in the environment and comparing it with stored data and incorporating the result of the comparison into the decision to deactivate and activate the mobile radio transmission. By the detection of the local arrangement of the mobile radio transmitter in the In the vicinity of the airport, the respective airport can be identified by comparison of correspondingly stored data and this information can also be used as a criterion in the event of failure of the SSR radar signal. The local arrangement of the mobile radio transmitter can be clearly detected by corresponding unambiguous indentfications of the cell information of mobile radio networks.

The object of the invention is also achieved by an above-mentioned device, wherein the means for detecting the presence in an aircraft by a radar receiver for receiving the SSR (Secondary Surveillance Radar) radar signal is formed with a carrier frequency of 1090 MHz, and a

Analog / digital converter and a microprocessor for processing the received radar signal is provided, which microprocessor is designed such that the mobile transmission is deactivated when the detected radar signal exceeds a predetermined amplitude over a predetermined period of time, and the mobile transmission is activated again, if detected radar signal falls below a predetermined amplitude over a predetermined period of time. Such a trained to receive the SSR radar signal radar receiver can be realized relatively inexpensive and small in size. By analog-to-digital conversion and appropriate software processing in a microprocessor certain criteria can be checked quickly and thus a reliable detection of presence in an aircraft can be achieved.

Advantageously, the detection device can be activated at periodic intervals. As already mentioned above, the power supply of the device is spared by the activation at periodic intervals and the life of the device is correspondingly increased.

The microprocessor may be formed by the mobile unit, which in any case includes a microprocessor. Thus, an implementation of the device according to the invention by appropriate programming of the microprocessor of the mobile unit and the corresponding application of a radar receiver together with analog / digital converter is possible. The power supply can be formed by rechargeable batteries. The charge can be made by solar cells to achieve an even longer life of the device.

In principle, the mobile radio unit itself can be used to determine position data, and the position can be determined via the cell information. A closer one

Position determination is possible if a GPS (Global Positioning System) receiver is provided and this is connected to the mobile radio unit.

According to a further feature of the invention, at least one sensor for measuring the acceleration, in particular a gyroscopic sensor, is provided and connected to the microprocessor.

For purposes of quality assurance or other purposes, at least one memory for storing the measurement data d is provided.

If a device for detecting the voltage of the power supply and possibly a display for displaying the sub ¬ is provided falls below a predetermined voltage, can be made in time for a renewal of the power supply.

If a unique identifier, for example the IMSI (International Mobile Subscriber Identity) of the mobile radio unit, is provided, which can be transmitted together with the data via the mobile radio network, an unambiguous assignment of the transmitted data can take place.

The reliability of the detection of the presence in a flight ¬ imaging can be increased, that a receiver to enable reception of a signal having a carrier frequency of 1030 MHz is provided and connected to the microprocessor. As a result, the signals emanating from the ground radar can be used as a further source of information for the reliable detection of the presence in an aircraft. When there is provided a device for detecting the location of mobile stations in the environment connected to the microprocessor and a database for storing the location of mobile stations, the reliability of detection of the presence in an airplane can be increased even further in the event that the SSR radar signal should not be sent.

The present invention will be explained in more detail with reference to the accompanying drawings. Show in it

1 shows a block diagram of a device according to the invention for the transmission of data via a mobile radio network;

FIG. 2 shows an example of a time profile of a radar signal; FIG. and

3 shows a flowchart for illustrating the method according to the invention.

Fig. 1 shows a block diagram of a device 1 for the transmission of data. The device 1 includes a mobile radio unit 2, which may be formed for example by a corresponding GSM module. The mobile radio unit 2 is usually connected to a SIM card 3. The corresponding data is transmitted via a corresponding antenna 4 via the mobile network. The mobile radio unit 2 is supplied with electrical voltage via a corresponding power supply 5, in particular corresponding accumulators. Commissioning can be done with a switch 6. In addition, a voltage regulator 7 may be provided.

According to the invention, a radar receiver 8 for receiving the SSR (Secondary Surveillance Radar) radar signal with a corresponding radar antenna 9 is provided in the device 1. The signal received by the radar receiver 8 is fed to an analog / digital converter 10, which may also already be integrated in the mobile radio unit 2. Thereafter, the digitized signal is supplied to a microprocessor 11, which also by the commonly existing microprocessor in the mobile unit. 2 can be realized. Now, if certain criteria for the received radar signal is met, for example, exceeded a predetermined signal amplitude over a predetermined period of time, this is assumed as a criterion for the presence in an aircraft and the mobile unit 2 is deactivated. The detection of the radar signal can be made at periodic intervals and the mobile unit 2 are activated again in the absence of the criteria or presence of other criteria. This ensures that the data transmission device 1 is activated again when it is no longer in an aircraft, or the aircraft has already reached its parking position.

A display 12 connected to the mobile radio unit 2 and its microprocessor 11 can monitor the state of the power supply 5. Through appropriate controls 13 different settings can be made to the device 1. A memory 14 connected to the mobile radio unit 2 or the microprocessor 11 can serve to store certain data. If a sensor 15 for measuring the acceleration, in particular angular acceleration, is provided, its signal can be used as another criterion for detecting the presence in an aircraft. In particular, gyroscopic sensors can absorb the slightest movements, as a result of which the presence in an aircraft moving toward the runway can be detected.

The radar receiver 8 and the associated radar antenna 9 can also be designed to receive a signal with a carrier frequency of 1030 MHz, in order to additionally be able to receive and process the signal usually originating from the ground radar. As a result, due to the detected signal shape of the 1030 MHz signal, the position relative to the ground radar can be deduced, and this can be used as a further criterion for the deactivation or activation of the mobile radio transmission.

The illustrated data transmission device 1 is relatively inexpensive and easy to produce and also in a small size and can thus be used for a variety of purposes. FIG. 2 shows a time diagram of a radar signal, in particular of an SSR response signal, of an aircraft as a function of the time t, the flight phase X being characterized by an increased amplitude of the signal. With appropriate choice of a

Threshold for amplitude As the flight phase or the presence in an airplane can be detected very easily and reliably. The signal shows in the time period to about 26000 seconds strongly fluctuating signals, which originate from passing or traveling aircraft, while the inventive device 1 is located in a warehouse of the airport. Between 27000 and 43000 seconds, the device 1 is located in a transport container next to the aircraft and is finally loaded into the aircraft. In the phase between about 43,000 and 69,000 seconds with relatively constant amplitude, the device 1 is in the aircraft and the aircraft in flight mode. This is the phase during which the mobile transmission has to be stopped. After the aircraft has landed, the SSR radar signal remains activated until the final parking position is reached. In the figure shown this is the phase between 69000 and 75000 seconds. Thereafter, the device 1 is unloaded and deposited, for example, in a warehouse for further treatment.

To detect the presence in an aircraft, the constancy of the amplitude As of the SSR signal is used. It is particularly advantageous if the amplitude, which is used as a criterion, is adapted to the threshold of the received signal. Such an adaptation of the threshold increases the sensitivity of detection of presence in an aircraft.

FIG. 3 shows a flowchart for illustrating the function of the subject invention, wherein block 100 starts the method according to the invention for detecting the presence in an aircraft. According to block 101 of the radar receiver is activated and checked in block 102, whether the radar signal is below a predetermined amplitude threshold As. If the signal is below the threshold As (which can also be adapted to the size of the received signal), a certain time interval is waited in accordance with block 103, before, according to block 104, a further time interval is reached. Therefore, the received radar signal is analyzed. According to query 105, it is again checked whether the radar signal is below a predetermined amplitude threshold As. If the signal is below a predetermined amplitude threshold As, then in block 106 a registration takes place in the corresponding mobile radio network and the device according to block 107 enables the transmission of data via the mobile radio network. At block 108, the unit is turned off. If the radar signal is above the predetermined threshold value in the query according to block 102, a predetermined period of time is waited in accordance with block 109 and, in turn, the received radar signal is analyzed in accordance with block 110. In the query according to block 111, it is again checked whether the radar signal above or below a predetermined

Amplitude threshold As is. If the signal is below a predetermined threshold, block 101 is continued. If the radar signal is above a predefined amplitude threshold value As, this is regarded as a reliable signal for the presence in an aircraft according to block 112 and deactivated according to block 113, the mobile radio unit 2 and returned to block 100. The consideration of additional input parameters, such as the signals of a gyroscopic sensor for detecting the angular acceleration or information about the local arrangement of mobile radio transmitters in the environment is not taken into account in this flow chart.

The method can be particularly easily modified according to the respective applications and implemented in software in a microprocessor, for example the microprocessor of the mobile radio unit.
