Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a data collection device that collects measurement data of various sensors such as a temperature sensor, stores the measurement data in a memory, and reproduces the data as necessary.

[0002]

[Prior art]

 A data collection device, usually called a data logger, collects data at many measurement points and prints it digitally on a printer.

[0003]

[Problems to be solved by the device]

 However, in such a data logger, a terminal board for connecting a large number of sensors, a printer, etc. are required, and there is a problem that the apparatus becomes large.

In view of the above points, an object of the present invention is to provide a data collection device that is small and lightweight and that can easily acquire data.

[0005]

[Means for Solving the Problems]

 According to the present invention, a card-shaped base body is provided with a sensor for detecting measurement data, a memory for storing the measurement data, and overall control and storing the data measured by the sensor in the memory. A control unit, a display unit for displaying data, and a power supply unit for supplying power to these units are provided, and the control unit fetches measurement data at predetermined intervals and stores it in the memory. The data collection device is configured to display the measurement data stored in the memory on the display unit.

【Example】

 FIG. 1 is a configuration explanatory view showing an embodiment of the present invention.

In the figure, reference numeral 1 denotes a card-shaped base such as an IC card, and the base 1 has, for example, a sensor 21 for detecting temperature, a sensor 22 for detecting humidity, and these sensors 21, 22. Measuring unit 31, 32 for amplifying the output of the device to a predetermined level or the like, a converting unit 4 such as an AD converter for converting the output of the measuring unit 31, 32 into a digital signal, and a micro controller for controlling the whole. A control unit 5 such as a computer, a memory 6 for storing data, a display unit 7 such as an LCD (liquid crystal display) for displaying data, an operation unit 8 such as operation keys for making various settings, and the like. A battery that supplies power to each circuit element unit, a power source 9 such as a solar cell, and the like are integrally provided. Further, the conversion unit 4, the control unit 5, the memory 6, the display unit 7, the operation unit 8 and the like are connected by a bus 10.

Before the start of measurement, the operation unit 8 refers to the display unit 7 to set the measurement start time, measurement time interval, alarm setting, and the like. For example, assuming that the operation unit 8 has an external configuration shown in FIG. 2, the power key 80 is turned on, the item key 81 is used to select a setting item, and the increase / decrease key 82 is used to increase / decrease the number. The registration key 83 is used to repeat the operations such as registering the set value to perform the setting.

When the data collecting device including the card-shaped substrate 1 is provided at a required place, the measurement signals detected by the sensors 21 and 22 are set to predetermined levels by the measuring units 31 and 32, The conversion unit 4 converts the signal into a digital signal, the control unit 5 performs necessary processing, and the memory 6 stores the data. Data is taken in and stored at predetermined time intervals programmed by the timer of the control unit 5.

After the measurement is completed, the substrate 1 is collected and the reproduction key 84 of the operation unit 8 in FIG. 2 is operated to display a digital display 71 on the display unit 7 and an analog trend display of the measurement data with respect to the passage of time. 72 or the like, or the control unit 5 can perform an alarm determination on the measurement data and display the alarm occurrence time and its value, or display the calculation result such as the average value or the integrated value.

As described above, by setting only the small and lightweight base body 1 at the required measurement location, collecting it later, and reproducing and displaying the data, the measurement result can be known, and Easy data collection for the purpose. If necessary, the measured data can be output to the outside for analysis by a personal computer or the like, and statistical processing.

It should be noted that the number of sensors 21, 22 may be one or more, and there are various measuring units 31, 32 and converting unit 4 depending on the sensor. It may be digitized by the control unit 5 or the like.

[0013]

[Effect of device]

 As described above, since the present invention is a data collection device in which a sensor, memory, display unit, etc. are integrated on a base such as one IC card, it is compact and lightweight, and has special connection and wiring for measurement. Since it is unnecessary and easy to carry, it can be moved with the object to be measured, can be used for quality verification of items such as in-vehicle, and can be widely used for various purposes. In addition, since it has a display unit etc., it does not require any other reading device, and it is possible to perform measurement, reproduction, and display only with this card-shaped substrate, and it is easy to obtain and collect data in a compact, inexpensive, and easy way. You can
