Description

  The present invention relates to a gas concentration measurement system that measures the concentration of gas in the environment, not a stationary type, but can be carried manually or by a vehicle.

  Examples of portable gas concentration measurement systems include portable small gas analyzers, gas sensor systems, and measuring instruments using detection tubes. Its uses include measurement of harmful gases and odorous gases during environmental assessments associated with construction of garbage disposal plants, measurement of harmful gases in new buildings that cause so-called sick house syndrome, and measurement of volcanic gases associated with volcanic activities. , Measurement of gas generated from or contained in soil due to soil contamination described in the Soil Contamination Countermeasures Law, measurement of gas that causes problems in manufacturing in factories and storage in warehouses, etc. It is used for various purposes. Furthermore, there are cases where the target gas is measured at a point away from the monitoring station or the measurement station in relation to air pollution or global warming.

  As a typical gas concentration measurement system, for example, there is a measurement device installed in a facility called a monitoring station or a measurement station installed by a country, a local government, a road related public corporation or the like. These are so-called stationary measurement systems, which usually provide online gas concentration values measured by official methods. In the case of the stationary type, the information on the measurement such as the measurement location, measurement conditions, and the person in charge of measurement / administrator is already known. It can be processed into useful information along with information. As a result, the local residents who are the recipients of the information can enjoy the information related to the measurement by browsing the Internet page.

  Unlike the cases described above, in cases such as when environmental assessment is performed for environmental assessment, etc., bring sampling equipment to the site and take the sample back to the laboratory for measurement, or carry it by hand or by vehicle. Measurement is performed in-situ using a general-purpose gas concentration measurement system. The portable gas concentration measuring system here refers to a portable small gas analyzer, a gas sensor system, measuring instruments using a detection tube, and the like.

  When performing measurements with a general gas concentration measurement system, the measurement environment information such as the measurement location, measurement date and time, measurement temperature, temperature, room temperature, humidity, etc. Information on the name, affiliation, and qualifications of the person in charge of measurement, such as the person in charge of measurement, the type of parts and equipment such as detector tubes used for measurement, and measurement conditions such as pre-treatment such as manufacturing time, expiration date, and suction processing, Most information about a measurement, such as a measurement value, is usually read by the measurer, filled in according to a predetermined format, and put together in a report after the measurement. In this case, it is difficult to completely avoid reading mistakes and entry mistakes of the measurer. In addition, information relating to measurement cannot be immediately transmitted to a desired partner such as a customer to be reported.

  Among these, there is one that avoids a reading error or a writing error of the measurer (for example, see Patent Document 1). The "gas detection member and gas concentration measuring device" described therein is provided with an information area for reading and writing information of the detection member on the gas detection member. It is possible to manage information such as date or expiration date, and to record information such as measurement location, measurement value or measurement condition, etc., making it possible to avoid entry mistakes by measurement personnel, Furthermore, by providing an RGB color sensor in the gas concentration measuring device, it is possible to avoid reading errors in the measurement results of the measurer by automatically measuring the gas concentration and the like. However, since the information related to the measurement is only stored in the information recording medium attached to the detection member, this case is again not suitable for immediately transmitting the information related to the measurement to the customer.

Recently, there is a portable gas concentration measurement system having a mechanism for transmitting measurement date and time and a measurement value as in the stationary type (see, for example, Patent Document 2). In this system, information on the measurement date / time, measurement value, temperature, and humidity can be acquired and converted into electronic data, but other information cannot be acquired and converted into electronic data for transmission. This system is usually intended to automatically acquire and transmit information for use by the receiver of information, and the sender and receiver of the information are the same. If the sender and receiver of the information are different, such as the measurement service contractor and the measurement service requester who is the customer, the information related to the measurement is generally shared by other methods or set as a precondition. It is necessary to keep.
