Gas-measuring system
A gas-measuring system is provided that is suitable for both mobile and stationary use. A mobile measuring device ( 2 ) with sensors ( 4, 5, 6, 7 ) for detecting gas concentrations and a base station ( 3 ) are provided for this purpose. The mobile measuring device ( 2 ) is inserted into a holder ( 31 ) of the base station ( 3 ) and the operating functions to the measuring device ( 2 ) are now switched over to the base station ( 3 ).
1. A gas-measuring system comprising:
a mobile measuring device comprising sensors for detecting gas concentrations, a first control and calculating unit for processing measured signals sent by said sensors and transmission means for data transmission;
a base station having a holder for receiving said measuring device, a power supply unit, alarm generators arranged in said base station, a second control and calculating unit for actuating said alarm generators and interfaces for supplying gas to be measured to said sensors and for data exchange between said mobile measuring device and said base station.
2. A gas-measuring system in accordance with claim 1 , wherein said base station is provided with a measured gas pump for sampling gas.
3. A gas-measuring system in accordance with claim 2 , wherein a sampling tube is connected to said measured gas pump and that said base station has a cable drum-like mount for said sampling tube.
4. A gas-measuring system in accordance with claim 3 , wherein an upper ring of said base station receives said holder for said mobile measuring device and a lower ring is designed as a base.
5. A gas-measuring system in accordance with claim 1 , wherein said base station is designed such that when said measuring device is inserted into said holder, said alarm generators are switched to a functional connection to said first control and calculating unit.
6. A gas-measuring system in accordance with claim 1 , wherein said base station further includes an interface for transmitting electricity to said measuring device.
7. A gas-measuring system comprising:
a mobile measuring device comprising a sensor for detecting a concentration of a gas, a mobile device control and calculating unit for processing measured signals sent by said sensor and a transmission device for data transmission;
a base station having a base station body, a holder for receiving and supporting said measuring device, a power supply unit, alarm generators connected to said base station body, a base station control and calculating unit for actuating said alarm generators, an interface for supplying gas to be measured to said sensor and an interface for data exchange between said mobile measuring device and said base station.
8. A gas-measuring system in accordance with claim 7 , wherein said base station is provided with a measured gas pump for sampling gas.
9. A gas-measuring system in accordance with claim 8 , wherein a sampling tube is connected to said measured gas pump.
10. A gas-measuring system in accordance with claim 7 , wherein said base station body includes a spool structure with a central support part and a mount for said sampling tube.
11. A gas-measuring system in accordance with claim 10 , wherein said base station body includes an upper ring connected to said central support part that defines a support to receive a holder for said mobile measuring device and a lower ring forming a base.
12. A gas-measuring system in accordance with claim 7 , further comprising switching means for switching said alarm generators to a functional connection to said mobile measuring device control and calculating unit upon said measuring device being inserted into said holder.
13. A gas-measuring system in accordance with claim 7 , wherein said base station further includes an interface for transmitting electricity to said measuring device.
