On the other hand, when the second loading platform 103 is folded, as shown in FIG. 5B, when the second loading platform 103 is turned upward 90 degrees or more, the upper edge of the U-shaped frame 103a is the long hole 108a of the guide member 108. It hits a roller 112 that is loosely fitted to a rivet 108b that is inserted into the support 101 and fixed to the column 101.
[0033]
Although the second loading platform 103 is manually turned, it is supported tightly and hits the roller 112 when turned 90 degrees or more, so that the folded state can be maintained.
[0034]
FIG. 6 shows a partially enlarged perspective view of the lock lever 107 and the guide member 108 as a lock mechanism. The guide member 108 has a shape that sandwiches the support column 101 and the handle 106, and is supported by a rivet 108b that penetrates the support column 101 and has a crimped tip so that the guide member 108 can move slightly in the horizontal direction at the portion of the elongated hole 108a. Further, the vicinity of the end of the lock lever 107 is pivotally supported by a rivet on the extended portion 108 c of the guide member 108. A flat reinforcing stopper 113 made of metal (for example, iron) is fixed to a position where the tip of the lock lever 107 hits the column 101 where the guide member 108 is attached.
[0035]
When the lock lever 107 is at a solid line position slightly obliquely above the horizontal and the top of the tip is in contact with the reinforcing stopper 113, the guide member 108 is slightly movable in the lateral direction through the elongated hole 108a. 106 can be guided to slide up and down.
[0036]
Next, after the handle 106 is slid to an appropriate position, when the lock lever 107 is pushed downward, the movable member 108 is horizontally elongated toward the lock lever 107 with the upper end of the tip of the lock lever 107 as a fulcrum. Move by 108a. When the lock lever 107 is in the horizontal position indicated by the dotted line, the entire end surface of the tip portion hits the reinforcing stopper 113 and locks the handle 106.
[0037]
FIG. 7 is a partially enlarged view for explaining a folding structure of the first cargo bed 104 and the leg member 105. The leg member 105 is foldably supported by a first link mechanism 114 attached between the support column 101 and the leg member 105. The first link mechanism 114 is attached to the connecting rod 114a that is pivotally attached to the support column 101, an L-shaped link member 114b that is attached between the connecting rod 114a and the leg member 105, and an L-shaped link member 114b. It consists of a knob 114c.
[0038]
The first loading platform 104 is connected to the leg member 105 via a second link mechanism 115 made of an L-shaped link member 105a. In addition, the first loading platform 104 is connected to the supporting column 116a via a third link mechanism that includes a connecting rod 116a that is pivotably attached to the column 101 and a coupling rod 116b that is pivotally attached to the first loading platform 104. 101 is connected in a reinforcing manner.
[0039]
When the connecting mechanism 114 is pushed to the support column 101 side with the knob 114c, the connecting rod 114a and the connecting portion 105a become obliquely straight with respect to the support column 101 as shown by the solid line, and at this time, The part 105b is grounded to keep the first and second cargo beds 104 and 103 together with the wheels 102 in a horizontal position.
[0040]
When the connecting mechanism 114 is pushed away from the support column 101 with the knob 114c, the connecting rod 114a and the connecting portion 105a bend at the first link mechanism 114 as shown by the dotted line, and the third link The connecting rod 116a and the connecting rod 116b of the mechanism 116 are bent, and the leg member 105 is pulled toward the support column 101. Accordingly, due to the presence of the second link mechanism 115, the first cargo bed 104 is also pulled toward the support column 101 side. And folded.
[0041]
As described above, the environmental measurement device cart 100 is useful for the measurement work of the environmental measurement device 1 in the opened state and also for the movement of the environmental measurement device 1, and can be carried alone in a folded state.

[0046]
The environment measuring device 1 and the portable device 11 are connected by a communication interface corresponding to optical communication (wireless communication) such as IrDA (infrared data association) or wired communication such as RS232C. A mobile phone terminal 21 is connected to the mobile device 11, and measurement data can be transferred to the outside such as a management center or office in real time or after a predetermined time after the environmental measurement in the environmental measurement device 1 is completed.
[0047]
FIG. 9 shows a block diagram of the environment measurement system of FIG.
[0048]
The environment measuring device 1 includes a sensor unit 2, a data logger unit 3, a communication interface 4, a key input unit 5, a power supply unit 6, an AC plug 7, and a battery 8.
[0049]
The sensor unit 2 is a sensor that measures physical data of the air environment, for example, a dust meter 2a for measuring the concentration of dust, a CO meter 2b for measuring the carbon monoxide concentration, and a carbon dioxide concentration. CO2 meter 2c, a temperature and humidity meter 2d for measuring temperature relative humidity, and an anemometer 2e for measuring wind speed. The sensor unit 2 may include at least one of these sensors, or may include other sensors for measuring other measurement items in addition to these sensors.
[0050]
The data logger unit 3 includes a CPU 3a and a memory 3b, and is connected to the sensor unit 2, the communication interface 4, such as IrDA or RS232C, the key input unit 5, and the power supply unit 6.
[0051]
The CPU 3a controls the overall operation of the environment measurement device 1 according to a control program stored in the memory 3b, and generates measurement data by calculating each sensor output of the sensor unit 2. That is, the CPU 3a stores a lookup table or conversion formula for each sensor (that is, dust meter 2a, CO meter 2b, CO2 meter 2c, temperature / humidity meter 2d, anemometer 2e) of the sensor unit 2 in the memory 3b in advance. If necessary, each physical quantity measurement data (that is, dust concentration data, carbon monoxide concentration data, carbon dioxide concentration data, temperature relative humidity data, or wind speed (or airflow) data) is called from the memory 3b as necessary. Execute the calculation process to convert.
[0052]
The memory 3b includes a semiconductor storage device such as ROM, RAM, EEPROM, or a combination thereof, and stores a control program and measurement data generated by the CPU 3a.
[0053]
The portable device 11 includes a communication interface 12 such as IrDA or RS232C, a CPU 13 as a control unit, a memory 14 as a storage unit, a communication interface 15, and a key input unit 16.
[0054]
Next, the operation of the environment measurement system having the above configuration will be described.
[0055]
First, when the AC plug 7 is connected to an AC power source and the environment measurement apparatus 1 is turned on, the key input unit 5 of the environment measurement apparatus 1 or a portable device (for example, a mobile computer) is provided at various places as required. 11 using various sensors (that is, dust meter 2a, CO meter 2b, CO2 meter 2c, temperature / humidity meter 2d, anemometer 2e) based on a measurement start command from 11 key input unit 16. Multi-point measurement of environmental physical data can be performed at once. It is also possible to measure only one or several selected air environment physical data.
[0056]
The CPU 3a of the data logger unit 3 performs an arithmetic process on the sensor output from each sensor of the sensor unit 2, generates measurement data, and stores it in the memory 3b. The measurement data generated by the CPU 3a is transmitted to the mobile device 11 via the communication interface 4 such as IrDA or RS-232C.
[0057]
The portable device 11 receives the measurement data transmitted from the environment measurement device 3 through the communication interface 12 under the control of the CPU 13 and temporarily stores it in the memory 14. The portable device 11 transmits the measurement data stored in the memory 14 to the portable communication terminal (for example, a digital portable phone) 21 via the communication interface 15 after the measurement of the environment measuring apparatus 1 is completed. The mobile communication terminal 21 transfers measurement data transmitted from the mobile device 11 to the outside (for example, a management center).
[0058]
Note that the connection of the portable device 11 and the portable communication terminal 21 to the environment measurement device 1 may be performed every time the environment measurement device performs measurement, and measurement data may be transmitted to the outside in real time, or in the environment measurement device. After all the measurements are completed, the portable device 11 and the portable communication terminal 21 may be connected to the environmental measurement device 1 and the measurement data may be transmitted to the outside at once. However, the latter method is efficient in work.
[0059]
Next, the above operation will be described with reference to the flowchart shown in FIG.
[0060]
First, the power supply of the environment measuring device 1 is turned on (step S1), and initial warm-up is performed (step S2). Next, a measurement standby state is entered (step S3). When a measurement start command is received from the portable device 11 during standby, measurement processing is started (step S4). Next, a T1 timer (built in the CPU 13, not shown here) for counting the measurement time T1 (for example, 1 minute) is started (step S5).
[0061]
Next, the CPU 3a activates each sensor of the sensor unit 2, that is, the dust meter 2a, the CO meter 2b, the CO2 meter 2c, the temperature / humidity meter 2d, and the anemometer 2e, and dust, CO, CO2, temperature, humidity, airflow Is measured (step S6).
[0062]
Next, the CPU 3a determines whether or not the T1 timer has expired (step S7). If the answer is no, the T1 timer continues to count time. If the answer is yes, the CPU 3a computes the sensor output from the sensor unit 2 to generate measurement data, and stores the generated measurement data in the memory 3b (step S8).
[0063]
Next, the CPU 3a determines whether or not there is a measurement data transmission request from the portable device 11 (step S9). If the answer is yes, the measurement data is transmitted to the portable device 11 via the communication interface 4, and then the operation is finished.
[0064]
On the other hand, when the power source of the portable device 11 is turned on (step S21), the state of the portable device 11 is confirmed (step S22). Next, measurement information designating a measurement item is input by the key input unit 16 (step S23), and the CPU 13 transmits a measurement start command accompanied with the measurement information to the environmental measurement device 1 via the communication interface 12 ( Step S24).
[0065]
Next, the CPU 13 transmits a command for requesting measurement data to the environment measurement device 1 via the communication interface 12 (step S25), and then the environment measurement device according to the request of the measurement data from the portable device 11 or R. The measurement data transmitted from 1 is received (step S26).
[0066]
Next, the CPU 13 determines whether or not the received measurement data is stored in the memory 14 (step S27). If the answer is no, it means that an abnormal state (for example, reception failure) has occurred, so the process returns to step S23, and the operations of steps S23, S24, S25, and S26 are repeated. If the answer is yes, the measurement is terminated (step S28).
[0067]
Next, the CPU 13 prepares data communication to the mobile communication terminal (for example, digital mobile phone) 21 (step S29). Next, the measurement data read from the memory 14 is transmitted to the mobile communication terminal 21 via the communication interface 15 (step S30), and the operation is finished.
[0068]
In this way, the measurement data measured and generated by the environment measurement device 1 is temporarily stored in the memory 14 by the portable device 11, and then collected in real time or after several measurements are completed, and the portable communication terminal 21 And further transferred from the mobile communication terminal 21 to the outside (for example, a management center).
[0069]
Actually, the transfer of the measurement data to the outside is performed in the portable device 11 and the portable communication terminal 21 after the measurement in the environment measurement apparatus 1 is completed, and the work is performed separately from the data logger unit 3 of the environment measurement apparatus 1. Therefore, workability is also easy.
[0070]
As described above, the embodiment of the present invention has been described. However, the present invention is not limited to this, and various modifications and applications are possible.
[0071]
For example, although the ground contact portion 105b of the leg member 105 is an integral part continuous with the connecting portion 105 in the above-described embodiment, it may be a discontinuous discontinuity near the center.
[0072]
The data logger 3 further calculates measurement data such as temperature relative humidity data, wind speed (or airflow) data, carbon monoxide concentration data, carbon dioxide concentration data or dust concentration data held in the memory 3b, Air environment evaluation information can also be generated.
[0073]
Further, when the portable communication terminal 21 is not carried, the measurement data is transferred to the outside by connecting the portable device 11 having temporarily stored the measurement data of the environmental measurement device to a telephone terminal such as a public telephone. It is also possible to do.
[0074]
