Definitions
- the present invention relates to a modular transmitter which has a sensor module and an electronics module coupled to the sensor module, the sensor module being coupled to the electronics module via a contactless interface, via which the energy supply to the sensor module and the data exchange between the sensor module and the electronics module take place.
- the interface can be designed in the manner described in European Patent Application No. EP 1 206 012 A2, inductive interfaces appearing particularly suitable.
- German patent application DE 13 703 854 discloses a modular transmitter, in which a sensor with a
- the measuring head is screwed, the measuring head being a transmitting and
- Receiving unit to be wireless with a central Communicate data acquisition unit.
- the sensors for example pH electrodes, are not electrically isolated from the measuring head. Rather, it can be assumed that there is a normal metallic contact between the measuring head and the sensors.
- the present invention is therefore based on the object of providing an electronic module for a modular transmitter, which overcomes the disadvantages of the prior art described.
- the object is achieved according to the invention by the electronic module according to independent claim 1 and the modular transmitter according to independent claim 5.
- the modular measuring transducer comprises a sensor module for recording a measured variable and the electronic module according to the invention, the sensor module and the electronic module being coupled to one another via a contactless interface, via which the energy supply of the sensor module and the data exchange between the sensor module and the electronic module take place, the electronic module furthermore has a transmitting or transmitting and receiving unit for wireless data exchange with a complementary receiving or receiving and transmitting station.
- the power supply of the electronic module can either be via a supply cable or self-sufficient, i.e. z. B. by photocells, using a
- the wireless data exchange between the electronics module and the complementary receiving or transmitting and receiving unit can take place, for example, by radio, ultrasound or light, in particular by means of infrared light.
- the type of data transmission chosen depends on the particular circumstances of the area of application. Infrared data transmission appears to be particularly suitable for use in laboratory operations with short ranges, with radio transmission being preferred for systems with larger ranges. Data transmission via a mobile network or via satellite is also suitable for special applications.
- the invention can generally be implemented with any sensors, in particular with potentiometric sensors, turbidity sensors, gas sensors, pressure sensors, fill level sensors, flow sensors, spectroscopic sensors, photometric sensors,
- Fig. 1 A measuring arrangement with a transmitter according to the present invention.
- the measuring arrangement shown in FIG. 1 comprises two modular transmitters, namely a modular opacimeter 1a and a modular pH transmitter 1b.
- the two modular transmitters 1a, 1b exchange data with a base station 2.
- the modular opacimeter 1a comprises an electronic module 10a, which has a circuit 8a for processing one received by the sensor module 7a Includes sensor signal. If appropriate, the circuit 8a can further comprise means for reading out device parameters of the electronic module 10a and the sensor module 7a.
- the electronic module 10a comprises a transmission unit 9a for transmitting and receiving data to the base station 2.
- the data transmission unit comprises an infrared transmitter 3a and an infrared receiver 5a, the base station 2 having a complementary receiver 4 or transmitter 6.
- the data exchange can take place, for example, according to the IrDA standard.
- the electronics module 10a is supplied with energy via a supply line 13a.
- the supply line 13a is used exclusively for energy supply, and in a further embodiment the supply line 13a is also redundant for data transmission z.
- a contactless plug connection is provided, which has a socket 11a, which is provided on the underside of the sensor module 10a, and a plug 12a, which is connected to the sensor module 7a, and engages with the bush 11a.
- the plug connection is preferably detachable.
- the plug connection can also be designed the other way round. That A plug extends from the underside of the electronic module, and the sensor module has a plug head for receiving the plug.
- a first cylindrical coil can be arranged in the lateral surface of the bushing 11a, the
- Plug 12a has a second cylindrical coil which is coaxial with the first cylindrical coil is arranged.
- the plug 12a and the socket 11b each have a coil with a ring core half, the end faces of the ring core halves being positioned flush with one another when the plug is arranged in the socket.
- the inductive energy transfer from the electronics module to the sensor module takes place via an AC signal which is fed by the electronics module.
- the amplitude of the AC signal is preferably modulated for data exchange between the sensor module and the electronic module (ASK according to the English term amplitude shift keying), but other types of modulation such as pulse width and frequency modulation are also conceivable.
- the data is transmitted to the sensor module by direct modulation of the AC signal fed in, with load modulation of the AC signal taking place for data transmission from the sensor module to the electronic module.
- FIG. 1 also shows a modular transmitter 1b, which is designed as a pH transmitter. It has essentially the same structure as the modular opacimeter 1a, so that only differences from the opacimeter described above are referred to below.
- the sensor module 7b comprises a pH electrode, which is connected to the electronics module 10b by means of the plug head 12b in the socket 11b of the contactless plug connection.
- the power supply to the modular transmitter 1b is decentralized, for which purpose a battery 13b is provided in the housing of the electronic module 10b.
- the local energy supply takes place via a fuel cell or via a photocell. The assignment of the energy supply types to the different sensor types is selected for illustration purposes only and does not describe a mandatory technical connection.
