Description

The invention relates to a universal connection system for sensors and to a method for detecting different sensors.

State of the art

In the living environment of disabled people with restricted mobility, the problem often arises that they can not or only unreliable operate normal keys and switches due to their disability. The operations of known devices such as devices for call triggering call systems or to operate environment control devices should therefore be as easy to use as possible.

Environment control devices, also referred to as environmental control devices, are understood to mean all devices with which a person with restricted mobility, for example a disabled person, can extensively control his 'environment' and thus enable an independent lifestyle. Operation can be done from the bed, seat or wheelchair.

• – Bedienung von Kommunikationshilfen, Telefon, Sprechanlagen
• – Bedienung von Fernseher, Radio, DVD-Player, Smartphones, Tablet-PCs
• – Öffnen und Schließen von Türen, Fenstern, Rollladen, Vorhängen
• – Ein- und Ausschalten des Lichts
• – Steuerung von elektrischen, behindertengerechten Betten
• – Bedienung der Heizung
• – Bedienung von elektrischen Lesehilfen (Blattwender)
• – Bedienung von Hilfsmitteln

Among other things, it is possible to perform the following functions:

• - Operation of communication aids, telephone, intercoms
• - Operation of TV, radio, DVD player, smartphones, tablet PCs
• - Opening and closing doors, windows, shutters, curtains
• - switching the light on and off
• - Control of electric, handicapped accessible beds
• - Operation of the heater
• - Operation of electric reading aids (sheet turner)
• - Operation of tools

In the environment control devices, a first operation of the input device triggers, for example, a scanning process in which the available options are offered, for example, in rows and columns and are selected by further actuations of the input device.

In addition to environment control devices, there are also accessible device adaptations, terminals and other electronic aids for the disabled (eg adapters for smartphones and tablet PCs, page turner), which has a socket for external special switches (sensors). In addition, in use with single or dual sensors (buttons, proximity sensors, etc.), a simplified operation similar to environment control devices is made possible.

Call systems are traditionally known by the term "nurse call systems". The basic functionality of this nurse call system and its basic operation, arrangement of operating elements, time sequences, etc. are specified in DIN 0834. These call systems call or search for help and exchange further information. DIN 0834 specifies the conditions for the human call system interface as well as for the time and function sequences.

To trigger the call must be installed on each bed in clinics, care facilities o. The like. As well as in washrooms, bathrooms and toilets from the calling, help requesting person, a patient, accessible call button. Persons who have limited ability to move, usually get a cord switch, which is electrically coupled to the call button.

To facilitate or facilitate operation for patients with restricted mobility, special switches adapted to the disability may be used. These special switches are called "sensors" in this area. The sensors include single sensors (mono sensors), dual sensors (dual sensors) and sensors with additional power supply (active sensors).

The connection plugs of single and dual-axis sensors are usually mostly so-called jack plugs. These are electrical connectors for the transmission of AC or DC voltage in the low voltage range (safety extra-low voltage, "SELV"). The design is standardized by the EIA as RS-453 and by the IEC under 60603-11 [1]. Depending on the number of poles, the jack plug has a different number of rings than the tip and the sleeve.

For critical functions, for example for the paging or assistance call systems, usually sensors with NC contacts (quiescent current) instead of normally open contacts (working current) are used to ensure intrinsic safety in the event of failure of the sensor. In the event of a defect in the sensor device as a result of a contact defect, line breakage, plug breakage or the like due to oversight or violence or a power failure with electronic sensors, an error is detected and signaled to the personnel.

For example, a "monitoring device for an analog telecommunication terminal, telephone jack and call system for the care of patients" is known (US Pat. DE 10 2004 035 124 A1 ). A monitoring device for call triggering by a telecommunications system has means for detecting the duration of a pending Dialing readiness of an analogue terminal connected to it. For this purpose, a monitoring device is connected between a respective subscriber line of the telecommunications system and a terminal for detecting a loop current through the terminal, wherein a switching means loads the respective subscriber line when the loop current is torn off. Thus, an interruption of the ladder or a disconnected phone can be seen.

The US 2012/0019306 A1 discloses an apparatus and method of a low power application of interface initiation during an interval when an interface of the interface initiation is in a disconnected state.

A disadvantage of previous plug-in systems is that they are always set to a type of sensor, usually a single sensor with mono jack and NO contact. The use of single sensors and dual-axis sensors with normally closed contacts on jack plugs are seldom used because they are incompatible with switches with normally open contacts. Active sensors require, in addition to a mono jack for the switching contact an additional power supply through another cable. A feedback option or serial communication via a common connection cable with a jack is not provided. The variety of different connectors, pin assignments and cable connections often lead to confusion in practice and can lead to malfunction or error-prone adjustments with adapters, etc.

The object of the invention is therefore to provide a uniform device for different special sensors with their different connection features while remaining compatible with a standard connection. This should prevent malfunction and ensure reliable operation of the special sensors for call triggering in paging systems and for the operation of environment control devices and devices or device adaptations.

• • dem Einsatz eines Algorithmus in Verbindung mit einem Mikrocontroller sowie eine geeignete Beschaltung für die Klinkenbuchse, um alle im Umfeld der Rufanlagentechnik im Pflegebereich vorkommenden Sensoren in Ausbildungen als Sondersensoren für behinderte Nutzer an einer einzigen Anschlussbuchse zu nutzen.

A universal connection system for special sensors as well as a method for the detection and use of different sensors are disclosed. The universal connection is a combination or a system consisting of:

• • a connector, in particular a jack plug, in conjunction with a connection or jack socket and
• • The use of an algorithm in conjunction with a microcontroller and a suitable wiring for the jack socket to use all occurring in the field of nurse call systems in the care sector sensors in training as special sensors for disabled users on a single socket.

The universal connection is formed by the use of the software algorithm and the corresponding wiring of the jack.

A jack socket is combined with the microcontroller, special connection technology and an intelligent software algorithm, so that single sensors and dual sensors in normally open and normally closed versions as well as active sensors (eg proximity sensor or acoustic sensor) can be operated on a single connection socket.

• • 2-poliger Klinkenstecker (Monostecker): Einfachsensoren, z. B. Taster
• • 3-poliger Klinkenstecker (Stereostecker): Zweifachsensoren, also zwei Einfachsensoren mit einem gemeinsamen Kontakt.

The jack plugs are designed in different connection variants with different functions:

• • 2-pin jack plug (mono plug): single sensors, eg. B. buttons
• • 3-pin jack plug (stereo plug): Two-axis sensors, ie two single sensors with one common contact.

• • 3-poliger Klinkenstecker (Stereostecker): Aktive Sensoren, die eine zusätzliche Stromversorgung benötigen
• • 3-poliger Klinkenstecker: Aktive Sensoren mit Möglichkeit einer seriellen Datenübertragung
• • 4-poliger Klinkenstecker: Sensoren mit zusätzlicher Signalisierungsmöglichkeit, z. B. Beruhigungslampe
• • 4-poliger Klinkenstecker: Aktive Sensoren mit Möglichkeit einer seriellen Datenübertragung.

The connection system can be extended with a different connector assignment, so that in addition to the switch contacts the power supply of active sensors, the signaling for a feedback and also a serial data transmission is possible:

• • 3-pin jack (stereo plug): active sensors that require additional power
• • 3-pin jack plug: Active sensors with possibility of serial data transmission
• • 4-pin jack plug: sensors with additional signaling option, eg. B. reassurance lamp
• • 4-pin jack plug: Active sensors with possibility of serial data transmission.

In digital technology, information is represented by electrical voltages. Usually, the information is binary coded and thus two voltage levels are required to represent the logic values: For digital signals, two voltage ranges are allowed, called high levels (also high) and low levels (logic level) ). The high level, the higher voltage, usually corresponds almost to the operating voltage, the low level as a lower voltage is usually close to 0 volts.

The jack is combined with the microcontroller. A microcontroller, in simple terms, is a small computer on a single semiconductor chip. This includes a processor that Programs can run programs, work and program memory and interfaces that allow communication with the environment (so-called peripheral functions). In other words, a microcontroller is a single-chip semiconductor computer system. The microcontrollers often also contain complex peripheral functions, serial or Ethernet interfaces, various outputs, as well as LCD controllers and drivers, possibly also via programmable function blocks. This makes it possible to use the microcontroller as a tripping device at light / Pflegerufanlagen with quiescent current and cable break monitoring. Due to the variety of settings via a PC software, almost any desired switching behavior can be produced at the switching outputs. For the connection system according to the invention, the microcontroller comprises the software algorithm oriented toward the objective of the connection system, which is used to determine the respective special sensor.

Through the use of the software algorithm, which is stored on the microcontroller, and the corresponding electronic wiring of the jack socket, all sensor variants can be connected to a single connection socket. The sensor type and function are automatically determined by the software algorithm and the system is set accordingly. The jack is 3 or 4-pin.

An algorithm in general is a clear guide to solving a problem or class of problems. Algorithms consist of finitely many, defined individual steps. Thus, they may be implemented as software algorithms for execution in a computer program. Problem solving transfers a specific input to a specific output. Due to the software algorithm mentioned above and the corresponding electronic wiring of the jack socket, all sensor variants mentioned above can be connected to this single connection socket or jack socket.

The signaling option (eg reassurance lamp) provided by a call system or by the device to be operated can also be supplied to the sensor (if supported) via this connection system without an additional connection cable.

Furthermore, a simple serial communication can be done via a contact on the jack. As a result, for example, a sensor can be parameterized or an information sent by the sensor can be evaluated.

The connection variants of the plug connectors, in particular the jack plug, are thereby recognized by the software algorithm. The software algorithm can therefore also be referred to as a recognition algorithm.

• – Erkennung, ob Stecker eingesteckt sind,
• – Erkennung Einfachsensor mit Schließerkontakt (Arbeitsstrom),
• – Erkennung Einfachsensor mit Öffnerkontakt (Ruhestrom),
• – Erkennung Zweifachsensor mit Schließerkontakten (Arbeitsstrom),
• – Erkennung Zweifachsensor mit Öffnerkontakten (Ruhestrom),
• – Erkennung aktiver Sensor (z. B. berührungsloser Näherungssensor),
• – Erkennung, ob ein zusätzlicher Kontakt für eine Signalisierungsmöglichkeit vorhanden ist,
• – Erkennung, ob Kontakte für eine serielle Kommunikation verwendet werden können u. dgl.

The universal connection for sensors according to the invention has the advantage that different connection variants are automatically detected:

• - Detecting if plugs are inserted,
• - detection of single sensor with NO contact (working current),
• - Detection of single sensor with NC contact (quiescent current),
• - Detection of two-axis sensor with normally open contacts (working current),
• - Detection of two-fold sensor with normally closed contacts (quiescent current),
• - detection of active sensor (eg non-contact proximity sensor),
• Detection of whether there is an additional contact for a signaling option
• - Detecting if contacts can be used for serial communication u. like.

For example, it would additionally be possible to detect an "unsafe" sensor with normally open contact. Such an "insecure" sensor may be, for example, a single sensor in a make contact embodiment. The problem arises that while this is used in practice, it is not allowed, especially in the field of nursing. A cable break or a switch defect can usually not be detected by the nurse call system.

Therefore, when such an "unsafe" sensor is detected, a warning signal may be triggered. This may in particular be a signal light, which is set, for example, so that it lights up as a warning for one minute.

It is also possible, for example, to activate a daily routine test procedure by software in which the functions of sensor, cable and plug are tested by pressing at a defined time. For example, a signal light goes on at 7:00 in the morning and lights up until the routine test procedure is started by pressing a button and the sensor is actuated once.

A method according to claim 15, characterized in that the detection of a dual sensor with normally open contacts is determined by • applying a digital change signal High / Low to the shaft contact ( 1 ) • Measuring: alternating signal to ring contact two ( 4 ) measurable • alternating signal not at the ring contact one ( 3 ) measurable and • alternating signal not at the tip contact ( 2 ) measurable: dual-axis sensor with normally open contacts; OR with shaft contact ( 1 ) fixed to ground: • digital signal high to ring contact1 ( 3 ) and measure • Digital signal High to peak contact ( 4 ) and measure • If both signals are high during the measurement, it is a two-fold sensor with normally open contacts Method according to one of claims 15 to 17, characterized in that the detection of an active sensor is determined by: • Positive test on dual-axis sensor with normally open contacts • Assignment of the connections: shaft contact ( 1 ) Ground, ring contact one ( 3 ) Operating voltage for sensor, tip contact ( 2 ) Signal High inactive or 0 V active • Ground is switched to shank contact ( 1 ) Positive voltage is applied to ring contact one ( 3 ) • Positive voltage at the tip contact ( 2 ) measurable: Active sensor: • Positive voltage at the tip contact ( 2 ) not measurable: Dual-axis sensor with normally open contacts A method according to claim 15, characterized in that a detection of a single or dual sensor with NC contact is determined by: • applying a digital change signal High / Low to the shaft contact ( 1 ) • Detect switch type: Alternating signal at the tip contact ( 2 ) Measurable: ^Simple, or dual sensor with NC contact; OR with shaft contact ( 1 ) fixed to ground: • detect switch type: digital signal high at tip contact ( 2 ) • Measure: When the signal at the tip contact ( 2 ) Is low, ie has a connection to ground, it is a single or dual sensor with normally closed contact Method according to one of claims 15 or 19, characterized in that a detection of the type single or dual sensor with Öffnerkontakt, so the quiescent current is determined by • actuation of the sensor at the tip contact ( 2 ) • absence of the test signal or: digital high applied and measurable • detection of a first sensor as actuated: single sensor; • or • actuation of the sensor on the ring contact ( 3 ) • absence of the test signal at the ring contact or: digital high applied and measurable • detection of a second sensor as actuated: dual-axis sensor. Method according to one of claims 15 to 20, characterized in that a detection of whether a contact for a signaling option is present, is determined by: • applying a digital change signal High / Low on the shaft contact ( 1 ) • Measuring: alternating signal not at the ring contact two ( 4 ) measurable: detection of a 4-pin jack plug ( 40 ) with feedback / signaling capability, since all other mono ( 20 ) or stereo plug ( 30 ) by design, a continuous connection from the shank contact ( 1 ) to the ring contact two ( 4 ) exhibit; OR with shaft contact ( 1 ) fix to ground: • digital signal high to ring contact two ( 4 ) and measure • If the signal is measurable as high and thus no connection to the shaft ( 1' ), the ring contact is two ( 4 ) and it is around a 4-pin jack ( 40 ) with feedback / signaling option. Method according to one of claims 15 to 21, characterized in that a detection of whether a sensor is connected with a possible serial data transmission, is determined by: • shaft contact ( 1 to ground • Transferring a serial digital code at the tip contact ( 2 ) • receiving a response in the form of a serial digital code at the tip contact ( 2 ): Sensor allows serial data transmission; OR • shaft contact ( 1 grounding • Transferring a serial digital code at ring contact one ( 3 ) • receiving a response in the form of a serial digital code at ring contact one ( 3 ): Sensor allows serial data transmission; OR • shaft contact ( 1 ) to ground • Transferring a serial digital code at the ring contact two ( 4 ) • receiving a response in the form of a serial digital code at the ring contact two ( 4 ): Sensor allows serial data transmission.
