2. Description of the Related Art When displaying fresh foods at stores,
In order to prevent food spoilage, the ambient temperature is set to, for example, 0
It is necessary to control the temperature so that the temperature is maintained within a range of from + 5 ° C to + 5 ° C. For this reason, fresh food retailers install a small temperature recording device for each refrigerated showcase for food display, measure and record the temperature inside the refrigerated showcase at predetermined time intervals, and store the recorded temperature data on a personal computer. By collecting and analyzing the data at a time, the temperature control status of the food is inspected. As a measurement system for this type of temperature management state inspection, a temperature measurement system 51 shown in FIG. 8 is conventionally known. The temperature measurement system 51 includes a temperature recording device 5 that performs temperature measurement and recording of the temperature data.
2, a personal computer 4, and a communication cable 5 for mutually connecting the temperature recording device 52 and the personal computer 4. In this case, the personal computer 4 sets measurement conditions for the temperature recording device 52, collects temperature data measured by the temperature recording device 52, and displays the temperature data.
Perform analysis.

The temperature recording device 52 includes a sensor unit 10, a control unit 56, a RAM 57, a ROM 58, and a driving battery (not shown), and a communication cable 5 is connected to a side surface thereof as shown in FIG. Connector 23 is provided. The sensor unit 10 outputs a sensor signal of a voltage corresponding to the ambient temperature to the control unit 56 under the control of the control unit 56.
The control unit 56 executes measurement control for the sensor unit 10, transfer control of temperature data to the RAM 57, and the like.
In this case, when the input of the measurement condition data output from the personal computer 4 is completed, the control unit 56 measures and records the temperature according to the measurement conditions corresponding to the measurement condition data. Further, the control unit 56 is configured to intermittently operate at, for example, one minute intervals in order to reduce power consumption. Specifically, the control unit 56 normally stops the operation while maintaining the sleep mode, counts the number of operation clocks, and starts when the count reaches a predetermined count. At the time of activation, measurement and recording are executed when it is determined that the measurement time has been reached according to the measurement conditions, and when it is determined that the measurement time has not elapsed, the mode is again shifted to the sleep mode. The RAM 57 temporarily stores measurement condition data and temperature data.
And the like.

In order to inspect the temperature control state of food, a temperature recording device 52 is installed in advance for each refrigerated showcase. At the same time, measurement condition data for setting measurement conditions for each temperature recording device 52 is created on the personal computer 4. Next, after the temperature recording device 52 and the personal computer 4 are connected to each other via the communication cable 5, the personal computer 4 outputs measurement condition data to the temperature recording device 52. Thereby, the temperature recording device 52
For example, the measurement conditions are set so that the temperature is measured and the temperature data is recorded every 30 minutes, and the first measurement and recording are performed. Next, the personal computer 4 is sequentially connected to each of the temperature recording devices 52, and all the temperature recording devices 52 are connected.
Set the measurement conditions for. Thereby, in each temperature recording device 52, the control unit 56 is activated intermittently at one minute intervals,
When the number of times of activation reaches a predetermined number (in this case, 30 times), the temperature is measured and recorded in the RAM 57. As a result,
The RAM 57 of each temperature recording device 52 stores temperature data measured at 30 minute intervals. Thereafter, for example, once a day, each temperature recording device 52 and the personal computer 4 are connected using the communication cable 5, and the temperature data in the RAM 57 is sequentially collected. Then, by analyzing the temperature data,
The temperature management state in the refrigerated showcase where each temperature recording device 52 is installed is inspected.

[0005]

However, the conventional temperature measuring system 51 has the following problems. That is,
In the temperature measurement system 51, it is necessary to transport the personal computer 4 and the communication cable 5 to the installation location of each temperature recording device 52 and to attach and detach the communication cable 5 to and from each connector 23 every time the measurement condition setting work and the data collection work are performed. . Therefore, in the conventional temperature measurement system 51, when setting the measurement conditions, the work of transporting the large and heavy personal computer 4 is complicated, and the work of collecting the data due to the attachment and detachment of the communication cable 5 is complicated. There is a problem.

A plurality of terminals are provided on the connector 23 provided on the lower surface of the temperature measuring device 52. Therefore, moisture, dust, and the like easily accumulate in gaps between the terminals and are difficult to remove. For this reason, the conventional temperature measurement system 51 has a problem in that various bacteria grow on the temperature recording device 52, which is not preferable for hygiene.

Further, in the conventional temperature measuring system 51, the control unit 56 of the temperature recording device 52 is configured to intermittently operate in order to reduce power consumption. On the other hand, the interval of the intermittent operation is difficult to arbitrarily change according to the use situation because the frequency of the operation clock and the count number thereof are fixed in advance. Therefore, for example, even when the temperature is set to be measured every hour, the control unit 56
Operate intermittently at one minute intervals. As a result, there is a problem that the power consumption of the driving battery of the temperature recording device 52 is large due to the unnecessary number of times of activation of the control unit 56.

In addition, in the conventional temperature measurement system 51, the temperature recording device 52 starts measuring and recording the temperature when the measurement condition data is input. Therefore, there is a problem that the measurement cannot be started at an arbitrary time. In addition, the measurement condition setting completion time for each temperature recording device 52 has a time difference corresponding to the transportation work of the personal computer 4 and the communication cable 5, the attachment / detachment work of the communication cable 5, and the communication time of the measurement condition data. For this reason, there is also a problem that it is difficult to make the measurement times of all the temperature recording devices 52 the same.

The present invention has been made in view of the above problems, and has as its main object to provide a data repeater and a measurement system that facilitate data collection work and measurement condition setting work. Another object is to provide a measurement system that is hygienic and can achieve low power consumption and the like.

The measurement data stored in the storage unit is output to the control device. In this case, the data relay is configured to be limited to the functions required for the data collection work, and thus is much smaller and lighter than a personal computer or the like. Therefore, data collection work becomes extremely easy.

[0012] The data relay according to the second aspect is the first aspect.
In the data repeater described above, measurement condition data for setting measurement conditions for the measurement device is input from the control device and temporarily stored in the storage unit, and the measurement condition data stored in the storage unit is transmitted via the communication unit. It is characterized by outputting to a measuring device.

In this data repeater, at the time of setting the measurement conditions, first, the control device outputs the measurement condition data and stores it in the storage unit in the data repeater. Next, the data repeater is carried to the installation location of the measurement device, and the measurement condition data stored in the storage unit in the data repeater is output to the measurement device via the communication unit. Therefore, as compared with the conventional temperature measurement system 51 which needs to carry a personal computer or the like, it becomes possible to set measurement conditions of the measurement device quickly and easily.

According to a third aspect of the present invention, there is provided a data repeater.
In the data relay according to the second or third aspect, the communication unit communicates with the measurement device by optical communication.

In this data repeater, communication is performed with the measuring device by optical communication. Therefore, since a communication connector is not required, the propagation of various bacteria can be prevented, resulting in extremely sanitary conditions. In addition, since the connection work of the communication cable is not required at the time of the measurement condition setting work or the data collection work, these works can be performed quickly and easily.

According to a fourth aspect of the present invention, there is provided a measuring system.
And a measurement device that performs measurement based on the measurement condition data and records the measurement data, wherein the measurement device normally stops operating and starts operating. It is characterized by including a control unit that sometimes controls measurement and recording, and an internal clock for the measuring device for activating the control unit at a predetermined time based on the measurement condition data.

In this measurement system, the control unit of the measurement device is started based on the measurement start time specified by the measurement condition data and the current time of the internal clock for the measurement device, and executes the measurement and the recording of the measurement data. I do. Therefore, it is possible to start the measurement by specifying an arbitrary time in the measurement condition data, and it is possible to activate the control unit only at the time of the measurement, so that power consumption is reduced.
The measuring device can be operated continuously for a long time by the driving battery.

[0018] The measuring system according to the fifth aspect is the fourth aspect.
In the measurement system described above, the data repeater includes an internal clock for the repeater, and is configured to be able to output the current time data of the internal clock for the repeater to the measurement device via the communication means. The present invention is characterized in that the current time of the internal clock for the measuring device can be corrected based on

In this measuring system, the current time data of the internal clock for the repeater is output to the measuring device via the communication means. On the other hand, in each measuring device, for example, the control unit corrects the current time of the internal clock for the measuring device based on the input current time data. Therefore, as a result of correcting the current time of the internal clock for the measuring device of each of the plurality of measuring devices to be the same as the time of the internal clock for the repeater, the measurement and recording in each measuring device are performed at the same time.

Therefore, the data collection operation can be performed quickly and easily.

Next, the collected measurement data DT is analyzed on the personal computer 4. At this time, the data relay 3 and the personal computer 4 are connected by the communication cable 5. Next, by performing a predetermined keyboard operation, the personal computer 4 outputs a transmission start signal S2 to the data repeater 3. At this time, the control unit 26 of the data relay 3 transmits the transmission start signal S
