DE102006005664A1 - Health condition monitoring method for driver or other machine driver, involves integrating health parameter measuring electro chemical and bioelectric and opto-electronic electrodes into steering wheel or other control element - Google Patents

Abstract

The method involves integrating health parameter measuring electro chemical and bioelectric and opto-electronic electrodes into a steering wheel (1) or another control element. The signals of health parameter measuring electro chemical or a bioelectric or an opto-electronic electrode (2 to 6) are combined with the hand from a health condition vector during contact. The condition vector is compared with a learned vector that is located in the permitted area for determining significant deviations in accordance with the statistical classification methods or the test theory.

Description

The Invention is used primarily in transportation. she can but also with the leadership machines of any kind are used.

At the Transport of machinery and materials is the intact health of the driver vital and / or damage-preventing. Are known in the vehicle arranged sensors such as anti-collision radar, speedometer, Accelerator position, ECG, pulse, etc., which calculate the traffic risk and cause a warning [accident prevention through driver monitoring, www.elektroniknet.de; Sharpening cars her eyes and view recognize stress at the wheel, VDI news from 24.03.2005; Senso car of a different kind, VDI news from 25.02.2005]. This measuring technique is due to the technology of the motor vehicle. When these signals from the driver it is like on the ECG for an average driver without medical knowledge and precautions, even if only mininal required, not practical for data collection.

task The invention is such a solution to be able to find that, without special preparation for everyone To provide health data.

The Invention is characterized in that sensors are so in the steering wheel or operating element are integrated, that their touching during the normal operation leads to health-related information. The Integration can be done in the form that selected areas of the steering wheel with conductive electrodes, optionally made of different materials, are occupied, the touch manually record bioelectric signals or these signals produce electrochemically. Other sensors integrated into the steering wheel are optical, tactile, temperature-measuring or similar others.

According to the invention these sensor signals to one of the individual information existing higher Statement on health summarized. This statement is for an individual created by a health state vector in a learning phase is formed from the sensor data. This sensor data can by means of a simulation facility e.g. be obtained from a doctor. For such a health condition vector represents a doctor or medical Establish the state of health and assign this one State vector, which is within allowable range for the guidance of a Motor vehicle or the operation of a machine must be located. In order to is the relation to the establishment of a health deviation or -endangering given by the signals from the sensors, as they are at a touch during the Steering process arise with this via a statistical classification method in the sense of an object recognition method and / or via mathematical Test theories are compared with the valid "healthy" state vector.

The Invention will be explained by way of example.

In 1 is a steering wheel ( 1 ). It has electrochemical electrodes ( 2 ) - (6). The electrode ( 2 ) is made of titanium, the electrode ( 3 tungsten, the electrode ( 4 ) made of tin, the electrode ( 5 ) of platinum and the electrode ( 6 ) of a conductive polymer. When touched by hand arise electrochemical voltages when one of the aforementioned electrodes is selected as a reference point, eg electrode ( 6 ). These tensions result from the electrolyte effect of the skin environment. This in turn is characterized by metabolic processes. Medication and narcotic injections as well as metabolic diseases can be detected with proper choice of electrodes [H. Ahlers (ed.): Early diagnosis of diabetes, JENASENSORIC eV Jena 2004].

Furthermore, two electrical electrodes ( 7 ) and ( 8th ) available. These measure bioelectrical stresses by hand and can thus provide information about the cardiovascular condition and / or stress situations [AI Grigoriev, RM Baevsky: Health and Cosmos, Inst. Med. Biolog. Problems, russ. I, Moscow 2001].

In addition, an opto-electronically measuring arrangement ( 9 ), which provides the geometric fingerprint for person identification and / or information about blood oxygenation.

From all these data, in a learning phase at the doctor or on a simulator, a health state vector, as in 2 represented, formed. The indices explain between which electrodes n and m the voltages U _{nm are} to be measured. By touching by hand during the steering operation, these voltages are repeatedly sampled and compared with the health state vector by means of known statistical classification methods and evaluated with regard to the health status of the vehicle driver.

If the state of health is well known, can also be integrated over the steering wheel Arrangement of Health Status Vector by the vehicle commuter or a suitable person in the surveillance system of the state of health.
