The invention relates to a method and device for transmitting sound, image and position data to a control centre in the event of an emergency by means of a mobile telephone.
Mobile telephones provide the opportunity to call an emergency control centre in the event of an emergency, or to send texts or images by SMS or MMS to an emergency control centre with the aim of placing an emergency call. A disadvantage here is that in the event of an emergency it is usually necessary to act so swiftly that little time is available for finding the telephone number of an emergency control centre and taking the appropriate action step by step. In addition, in situations where certain persons pose a threat, it is difficult or impossible to place such an emergency call unnoticed without attracting the attention of the person who poses a threat.
The invention is therefore based on the task of providing a method and device for transmitting sound, image and/or position data to a control centre in the event of an emergency by placing an emergency call using a mobile telephone without the need to select a telephone number of a control centre and initiate the transmission of image, sound and/or position data individually, and without attracting the attention of third parties in the process.
This task is solved by a method according to claim 1 and by a device according to claim 10. To that end a mobile telephone is envisaged and equipped with a camera, a microphone, a positioning device for determining position data and software which controls the recording and the transmission of image, sound and position data. The sound data is also referred to as audio data and the image data also referred to as video data. The method is characterised in that a safety application is activated by accessing the software and that this automatically triggers the recording of image data by the camera, the recording of sound data by the microphone and the determination of the mobile telephone's position data by the position sensor. The image and sound data recorded is compressed losslessly. In addition, a connection to a control centre is established automatically. The compressed audio and video data as well as the position data is automatically transmitted to the control centre. The only action required by the user is to call up the software on his/her mobile telephone. All other steps take place automatically and without the need for further action. The control centre automatically matches the incoming image, sound and position data to an emergency call, and treats it as such. It is beneficial that the image data and position data is displayed on a display device in the control centre. The sound data is reproduced over a speaker. To that end it is beneficial that the control centre is equipped with a display device and a speaker. The incoming data at the control centre can be registered by one person. That person can get an impression of his/her own regarding the emergency on the basis of the image, sound and position data without needing a further conversation with the person who has placed the emergency call. The person placing the emergency call can thus avoid attracting attention; this is important particularly in situations where the emergency derives from a threatening situation.
The control centre may be an emergency call centre, control centre or operations centre running the operations of more than one organisation. These include public organisations such as the police, fire service, rescue services and technical relief agency. The control centre may moreover be a private organisation, for example belonging to a security company or a mobile emergency service. The control centre may also constitute a private individual acting as the contact person. For children, the control centre may be the landline or mobile telephone of the parents. In the method according to the invention, it is possible to send the image, sound and position data to more than one control centre simultaneously, for example to an emergency call centre and to a private individual acting as the contact person.
It is beneficial that the image data recorded comprises not just individual images, but image sequences and films with the accompanying sound data. In that way, the control centre can register not only the location of the occurrence, but also the time sequence of what is happening.
Compression of the image and sound data shortens the time required to transmit the data from the mobile telephone to the control centre. This is especially important in emergencies.
The image data and sound data recorded is compressed losslessly before it is transmitted to the control centre. This means that the image and sound data correspond exactly to the original data after decompression. This is important as the original data from the image and sound data recorded is to be available for subsequent evaluation of the emergency. With the help of this original data it may be possible to obtain information on the causes of the emergency, a perpetrator or witnesses.
It is beneficial that the position data is likewise compressed before it is transmitted, allowing the data to be transmitted quickly.
Transmission of the data can be terminated from the mobile telephone or in the control centre.
Carrying out the method is made possible by software that can be loaded into the memory of a programmable mobile telephone in the form of an application, known as an app. The method is started by activation of the software. It is beneficial that a start function is assigned to a button of the mobile telephone. If the software is loaded in a main memory of the mobile telephone, the recording and transmission of image, sound and position data can be started by pressing this button. Placing the emergency call is initiated by input of a single command. A mobile connection to a control centre is established automatically by the method. Image, sound and position data recorded by the mobile telephone is immediately transmitted to the control centre by the mobile connection. Special software recorded at the control centre can ensure that the data is displayed, stored and managed at the control centre.
It is beneficial that a hierarchy applies for the transmission of the data to the control centre. The position data is always transmitted to the control centre. If the mobile connection should not be good enough for compressed image data, compressed sound data and position data to be transmitted in a short period of time and to a good standard of quality, the control centre can at least identify from which mobile telephone and from what position an emergency call was placed. If the mobile connection is of good quality, the compressed image and sound data is also automatically transmitted in addition to the position data.
According to an advantageous embodiment of the invention, the mobile telephone records the time and transmits it to the control centre. The video, audio and position data can thus be recorded and stored in combination with a time and are correspondingly available for documentation purposes.
According to a further advantageous embodiment of the invention, the telephone number assigned to the mobile telephone is stored. In addition, further data for the mobile telephone or the person placing the emergency call can be stored, such as the IP address of the mobile telephone. This makes it possible subsequently to clearly match the data for the emergency stored in the control centre to a mobile telephone and therefore also to a person under whose name the mobile telephone is registered.
According to a further advantageous embodiment of the invention, the image data, sound data and position data is transmitted to the control centre in real time.
According to a further advantageous embodiment of the invention, the transmitted image data, sound data and position data is stored in a memory at the control centre. This ensures that it is documented accordingly. The documentation is available for subsequent investigations. The data remains available even if the mobile phone is damaged or destroyed in the emergency.
According to a further advantageous embodiment of the invention, the image, sound and position data is also stored at the mobile telephone provider. It can subsequently thus also be retrieved from there.
According to a further advantageous embodiment of the invention, the image data and sound data is decompressed after transmission to the control centre. The decompressed image data and sound data is then stored in a memory. This may be a memory at the control centre and/or a memory in the mobile telephone. In addition the data may also be stored in a memory of the mobile telephone provider.
According to a further advantageous embodiment of the invention, the position data is determined by means of the Global Positioning System GPS.
According to a further advantageous embodiment of the invention, the software is recorded in a memory of the mobile telephone in the form of an application.
According to a further advantageous embodiment of the invention, the data is transmitted from the control centre to the mobile telephone. This enables information to be forwarded from the control centre to the person placing the emergency call. The format of the data and the output of data via the mobile telephone to the person placing the emergency call depend on the nature of the emergency. The data may for example comprise voice or sound data that is output via a microphone on the mobile telephone. In addition, data in the form of text or image symbols can be transmitted and output on a monitor or a display device of the mobile phone. For input of the data at the control centre, it is beneficial that the control centre is equipped with suitable equipment such as a microphone or a keyboard. Furthermore, the control centre is preferably equipped with a transmitter device for transmitting the data to the mobile phone. Communication between the control centre and the person placing the emergency call is made possible in this way.
The device according to the invention for the transmission of sound, image and/or position data to a control centre is equipped with a programmable mobile telephone and a control centre. The mobile telephone features a camera, a microphone, a positioning device and a control device. The control device is equipped with a memory in which software is stored. Execution of the software, when accessed, automatically starts the recording of image and sound data and triggers the determination of position data, compresses the image and sound data, establishes a connection with a control centre and assures the transmission of data from the mobile telephone to the control centre. The control centre is equipped with a reception device to receive the data transmitted, as well as a display device.
It is beneficial that the control centre is equipped with a computer that is capable of receiving and processing the data transmitted by the mobile telephone. In particular the data can be stored in a memory of the computer and displayed on a display device of the computer. The computer furthermore features an input device via which the data can be input. The latter can be transmitted to the mobile telephone by contactless means via a mobile connection.
According to a further advantageous embodiment of the invention, the control centre is equipped with an alarm device which triggers an alarm when image data, sound data and position data is received from a mobile phone of the device.
According to a further advantageous embodiment of the invention, the control centre is equipped with an input device and with a transmission device, which transmits data to the mobile telephone.
According to a further advantageous embodiment of the invention, the control centre is equipped with a decompression device, which decompresses the compressed image and sound data.
The mobile telephone of the device according to the invention may be used by private individuals. In addition, it may be integrated into emergency vehicles or into public transport vehicles. It may also be permanently installed in areas accessible to the public. The device thus not only facilitates the placing of an emergency call to a control centre, but can also act as a deterrent to potential offenders. A subjective sense of safety may moreover be enhanced. In addition, storage of the data transmitted to a control centre facilitates the reconstruction of a progression of events at a later date.
