Specific Example

     1 shows a block diagram of a portable measuring device for explaining the present invention. The mobile measuring device A is a personal measuring device as a measuring device which calculates an analysis result based on a GPS receiver and a gas measuring system as position information detecting means for detecting position information of a gas analyzer and a measuring point measured by the gas analyzer. It is configured to include a computer.

     The gas analyzer 1 is, for example, a time-of-flight mass spectrometer that ionizes a sample to be analyzed, and then applies a constant energy to accelerate or accelerate the flight by using a change in flight speed resulting from the difference in ion mass during flight. It is to specify the kind. 1a is a probe composed of a tube for sucking a sample gas and delivering the sample gas to a gas analyzer. The gas analyzer is portable and can be carried with you.

     The GPS receiver 2 detects the position of the measurement point by receiving the emergency transmitted data from the GPS satellite which is the satellite. The location information consists of latitude and longitude data. Here, the GPS receiver is installed independently of the gas analyzer, but the GPS receiver can be combined with the gas analyzer.

     The computer is a general-purpose portable PC, which includes an operation unit 5 including a keyboard and a mouse, an operation processing unit 6 including a CPU and an input / output interface unit, a display unit 7 including a display such as a CRT or LCD, a ROM, a RAM, and a hard disk. A storage unit 8 is included. It also includes an output unit 9, such as a printer connected to a computer as a peripheral device, can be attached and detached as necessary. The computer is configured to be mobile in connection with a GPS receiver and a gas analyzer.

     Fig. 2 is a flowchart for explaining the operation of the present measuring apparatus and shows the processing performed in the calculation processing section. Software for such an operation process is stored in a ROM or a hard disk of a storage unit.

     First, the gas analyzer is operated, a sample gas is injected from the probe 1a into the gas analyzer, and the gas analyzer measures the components or concentrations contained in the sample (S1). Next, the measured component or concentration is compared with the substance information previously stored in the storage unit (S2) to determine whether or not a dangerous amount is included in a predetermined amount or more (S3: NO). If not dangerous, go back to step 1 and repeat the measurement of the sample. The measurement period at this time can be selected by adjusting the time. If the toxic component contains a certain amount or more (S3: YES), the risk level of the component is diagnosed (S4). The risk level determination is made in 10 steps, for example, and the risk level corresponding to the concentration range for each component can be set in the table in advance, and the table is stored in the ROM of the storage unit.

     Next, the calculation processing unit 6 receives the position information detected by the GPS receiver 2 (S5) and performs a second sample measurement in the gas analyzer (S6), and diagnoses the next danger level (S7). Then, it is checked whether the sample measurement is repeated a predetermined number of times (S8). If the predetermined number of times has not been executed (S8: NO), the process returns to step 6 and the sample measurement is repeated. Repeating the sample measurement is intended to accurately predict the safety by monitoring whether the harmful component increases or is constant over time. When the sample measurement of the predetermined number of times is finished (S8: YES), the calculation processing unit outputs various analysis results together with the position information of the measurement point based on the measurement data of the analysis system (S9). This output result is displayed on the screen of the display unit 7.

That is, the position information and the analysis result of the mobile measuring device are transmitted to the other measuring device, and the position information and the analysis result of the other measuring device are received. As a result, the mobile measuring device A 'displays positional information and analysis results measured at a plurality of measuring points, including the measurement results at different points, on the display unit 7 of the computer.

     The present invention can adopt various embodiments described above. For example, in the above embodiment, the computer used as the data processing means is provided separately from the gas analyzer, but the gas analyzer and the computer can be integrated.

     In addition, the data processing means can diagnose the dangerous level of the object to be measured, so if the measured data exceeds a certain level, it will be displayed on the display or other appropriate means.In case of emergency, the automatic contact with the location information will be sent to the designated contact. An automatic notification means 10 can be added.

     In the above embodiment, the display of the position information and the analysis result is shown on the screen of the display unit as an example. In addition, in the above embodiment, the GPS positioning system is used to detect the location information, but in the present invention, a method of applying a positioning system using a communication satellite other than GPS is also possible. Furthermore, in the above embodiment, the gas analyzer is exemplified as the measuring device. However, the present invention is not limited thereto, and the present invention can be applied to a measuring device such as a radiometer.

     According to such a configuration, since the mobile measuring device outputs the location information of the measurement point together with the analysis result, it is possible to know exactly where the analysis result is data, and since the location information includes the location information, a quick response such as automatic notification can be achieved even in an emergency situation. It is possible.

     In addition, according to the present invention, it is possible to display a plurality of data including its own measuring position and a different point in each measuring device, so that the analysis result can be more multifaceted and comprehensively grasped.
