Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a data collection and storage device that stores six sets of collected data in a removable storage unit.

[Prior art]

Conventionally, when recording and analyzing various types of data, it was uneconomical to install analysis equipment at all locations where data was collected, so it was common practice to collect the recorded data in one place and analyze it there. many. In this case, if immediacy is not required for data analysis, it is conceivable to use a removable structure for the storage section that stores data, and to periodically collect the storage section.

However, if the data collection locations are different and the types of data collected are different depending on the data collection location,
In many cases, the storage method is optimal for each type of data, and in this case, the storage unit needs to be compatible with that storage method, but if the storage method is different, there will be no compatibility and the storage unit will be The drawback was that it was not possible to provide versatility.

[Object and structure of the invention]

Therefore, an object of the present invention is to provide a data collection and storage device that can use a storage section with general versatility.

In order to achieve such an object, the present invention provides a storage method specifying means for generating a specification 5 specifying a storage method in the data storage section, and a storage method determination means for decoding the specified signal in the data storage section. A means is provided to memorize according to the decoding results. Hereinafter, the present invention will be described in detail using drawings showing embodiments.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention.

In the figure, 1 is a collection unit that collects external information, 2 is a removable storage unit that records data obtained by the collection unit 1, 31 to 3n are sensors that convert external information into electrical signals, and 4 is a removable storage unit that records data obtained by the collection unit 1. 5 is a storage method specifying means for generating a specification signal for specifying the data storage method and the size of the memory area for the storage unit 2; 6 is a data collection function unit; 7 and 8 are the collection unit 1; a connection function unit for transmitting data to and from the storage unit 2; 9 is a storage function unit; 1;
Reference numeral 0 denotes a storage method determining means for decoding the designated signal, 11 a memory management means for managing data storage locations based on the determination result of the storage method determining means 10, and 12 a memory.

When the storage unit 2 is connected to the collection unit 1, it sends a start signal to the collection unit 1, and when the collection unit 1 receives the start signal, it sends out a designation signal from the storage method designation means 5. It looks like this. This designation signal includes the memory area of the storage unit 2 (only the size, not including the address) and
It includes a signal that specifies the data processing method (for example, whether or not to store the data with time information, or whether to calculate the maximum value), and the type of the specified signal is the type of data. There are as many types as there are types.

After the storage method specifying means 5 has sent out all types of specifying signals, it sends out a signal indicating the end of sending out the specifying signal.

Upon receiving the designated signal, the storage method determining means 10 determines the absolute address of the memory 12 from the memory area information included in the designated signal, and stores data representing the address and data representing the processing method in the designated signal in a data table. It is designed to be stored.

When the memory management means 11 receives collected data from the collecting section 1, it stores the data in order at absolute addresses determined by the storage method determining means.

FIGS. 2 and 3 are flowcharts showing the operation of the apparatus configured as described above. FIG. 2 shows the operation of the collecting section 1. In step 100, the collecting section 1 is powered on, and in step 101, it is determined whether or not the sending of the designated signal has been completed. At this point, this step is naturally determined to be "NO". When the storage unit 2 is connected to the collection unit 1, the storage method designation means 5 of the collection unit 1 sends out a designation signal as shown in step 102, and in step 103 it is determined whether the designation signal has been sent normally. A determination is made whether or not. If the determination in step 103 is "NO", the process of sending out the designation signal shown in step 102 is performed again; however, if the determination in step 103 is l'-YESJ, the flow returns to step 101. Since the collecting section 1 is configured to send out designation signals for only the types of data to be sent, the flow repeats the loop from step 100 to step 103 the same number of times as the number of data types. Then, when all the designated signals are sent out, step 101 is determined as [YESJ, so as shown in step 104, the end of designated signal sending is notified to the storage unit 2, and the collected data sending process shown in step 105 is performed. .

FIG. 3 is a flowchart showing the operation of the storage section 2.

In the same figure, power-on processing of the storage unit 2 is performed in step 200, and it is determined in step 201 whether or not there is a notification of completion of transmission of the specified signal.Since the initial determination is "NO", step 202 It is determined whether the designated signal shown in is received. If the determination in step 202 is "NO", 70- cycles through the loop of steps 201 and 202 until the designated signal is received, but if the determination in step 202 is l'-YESJ, the designation shown in step 203 is performed. The signal is decoded and as a result, data representing the absolute address of the mesori and the processing method is stored in a data table as shown in step 204. Then, the flow returns to step 201, so steps 201 to 204 are cycled until the designated signal transmission end notification is received, but when the designated signal transmission end notification is received, step 201 is determined to be "YESJ". Therefore, it is determined whether the data shown in step 205 has been received.

If step 205 is determined to be l'-YESJ, as shown in step 206, it is determined whether the received data is registered in the data table, and if "NOJ", the flow returns to step 205 υ, Steps 205 and 206 are repeated until step 206 is determined to be ``YESJ.'' When step 206 is determined to be ``YESJ,'' the processing content is recognized by referring to the data table as shown in step 207, and the recognition result is Accordingly, any one of steps 2081 to 208n is performed.

As described above, this processing is, for example, processing of whether or not to add time data or whether or not to obtain the maximum value.

Then, when the process of step 208 is completed, step 2
Processing to find the memory address to store as shown in 09,
That is, since address data is read from the data table, the data processed in step 208 is stored sequentially as shown in step 210. This storage is controlled by the memory management means 11. Then, the flow returns to step 205), and from then on, steps 205 to 210 are cycled each time the next data is received.

Note that the end step is omitted in FIGS. 2 and 3.
