is a control unit including a CPU that controls the above 1 to 4.

FIG. 3 is a block diagram of a conventional portable data acquisition device called a portable synchroscope, which is equipped with an analog signal data input function from an external sensor, a data memory function, a function selection key, etc. Corresponding parts are given the same reference numerals. In the figure, 6 is a signal input section that takes in and amplifies an analog signal from a sensor or the like (not shown), and 7 is an A/D converter that converts the analog signal into a digital signal.

Next, the operation will be explained.

In FIG. 2, when desired data such as numerical values and characters are input by operating the keyboard 3,
This data is processed by the control section 5 and filed in the memory 2, and is also displayed on the display section 1. Furthermore, the data filed in the memory 2 can be recalled by operating the keyboard 3 and displayed on the display unit 1 when necessary. In addition, by communicating with the same external device, personal computer, or other external device via the communication interface 4, data in the memory 2 can be input to the external device, or data can be imported from the external device and transferred to the memory 2. It can be filed in .

In FIG. 3, an analog signal from an external sensor or the like is taken in by a signal input section 6, converted into digital data by an A/D converter 7, and then this data is sent to a control section 5.
The data is filed in the memory 2 through the ROM 2 and displayed on the display unit 1. Also, when displaying input signal waveforms, etc.,
The range of waveform display can be selected using the function selection keys provided on the keyboard 3.

[Problems to be Solved by the Invention] Since the conventional portable data collection device is configured as described above, when this device is used for periodic inspections of plants, etc., daily patrol inspections, etc., it is necessary for workers to Data is collected only by manual key input of numbers, characters, etc. or by signal input, so data can only be collected during periodic patrols, and during inspection intervals. There was a problem that data could not be collected.

[0008] This invention was made to solve the above-mentioned problems, and in addition to manual control of the key input function and signal input function, it is possible to automatically import data every time a preset condition is met. The object of the present invention is to obtain a portable data collection device having a file function.

[0009]

[Means for Solving the Problems] A portable data collection device according to the present invention is capable of manually inputting and filing numeric and character data inputs and signal data inputs, as well as automatically inputting and filing them when conditions are met. In order to make this possible, in addition to the keyboard for inputting data, signal input section, memory, display section, and communication interface for data transfer, input conditions are monitored, data is automatically input when the conditions are met, and a file The system is equipped with a control section to

0010

[Function] The portable data collection device of the present invention can input data manually on site, and can also collect data from devices that operate intermittently or devices with long patrol intervals periodically or when conditions are met. It can be collected as data.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In Figure 1, 1 to 4, 6, and 7 are shown in Figures 2 and 3 above.
This is the same as the conventional one shown in , and the explanation will be omitted.

In FIG. 1, 8 is a memory in which a data collection condition program, a collection condition monitoring program, etc. are stored, and 9 is a timer.

Next, the operation will be explained.

[0014] A portable data collection device according to the present invention includes:
By connecting it to a device from which data is to be collected, data collection conditions are monitored according to the program stored in the memory 8. When the conditions are satisfied, data such as numerical values and characters input by key input or signal data from the signal input section 6 are automatically input and filed in the memory 2. If the following conditions are met, data is automatically input again and filed in the memory 2.

Data collection conditions include, for example, time conditions such as the above-mentioned patrol inspection interval. This temporal condition is monitored by monitoring the time signal from the timer 9. In addition, various other conditions can be set as the data collection conditions, such as the time when data from a sensor or the like input from the signal input section reaches a predetermined value. If data collection conditions and data collection methods differ depending on other inspection items and inspection targets,
By setting conditions to the software in the memory 8, data necessary for the inspection target can be collected manually or automatically.

Note that the keyboard 3 in FIG. 1 may be input by touch switches on the display unit 1, and the memories 2 and 8 may be external memories such as hard disks or memory cards in addition to the IC on the board. good. Data processing software can also be installed via communication from an external memory such as a hard disk or memory card. Moreover, each function of the embodiment can also be included in a stationary type device such as a personal computer.

[0017]

[Effects of the Invention] As described above, according to the present invention, input data such as numerical values, characters, etc. and signal input data from sensors, etc. are monitored according to set conditions, and when the conditions are met, the input data is automatically By temporarily placing this device on-site and automatically collecting data, it becomes possible to collect periodic data and condition-fulfilling data between patrol intervals, streamlining data collection. It also has the effect of allowing more accurate data analysis.
