Abstract
A checking unit as well as to a process are provided for checking a gas-measuring device. With the checking unit and process it is possible to efficiently detect measured gas values with a gas-measuring device.
Claims15
A checking unit for checking a gas-measuring device, the checking unit comprising:
- a first data interface;
- a second data interface;
- and
- a control unit configured:
- to receive a first request message, which indicates a request for providing at least one measured gas value of a predefined type of gaseous substance from a network unit via the first data interface,
- to transmit a second request message, which has a request for sending information related to a potential presence of at least one gas sensor type of the gas-measuring device to the gas-measuring device via the second data interfaces;
- to receive a reply message, which has the information related to the potential presence of the at least one gas sensor type, from the gas-measuring device via the second data interface;
- to derive from the information of the reply message whether a gas sensor type that corresponds to the predefined type of gaseous substance is present in the gas-measuring device, and,
- in a case of a derivation result of gas sensor type presence, to send a third request message to the gas-measuring device, which indicates a request to transmit the at least one measured gas value of the predefined type of gaseous substance to the control unit and to provide the at least one measured gas value to the network unit upon receipt of the at least one measured gas value.

A process for checking a gas-measuring device, the process comprising the steps of:
- receiving a first request message from a network unit via a first data interface tail, wherein the first request message indicates a request for detecting at least one measured gas value of a predefined type of gaseous substance;
- transmitting a second request message to the gas-measuring device via a second data interface, wherein the second request message has a request for sending information related to a potential presence of at least one gas sensor type of the gas-measuring device,
- receiving a reply message from the gas-measuring device via the second data interface, wherein the reply message has the information related to the potential presence of the gas sensor type,
- deriving, on the basis of the information of the reply message whether a gas sensor type that corresponds to the predefined type of gaseous substance is present in the gas-measuring device,
- sending, in case of a positive derivation result, a third request message to the gas-measuring device, which indicates a request for transmitting the at least one measured gas value of the predefined type of gaseous substance to the checking unit, and
- providing, upon receipt of the at least measured gas value, the at least one measured gas value to the network unit.
