It is configured to convert into an analog value or BCD (binary coded decimal) code and output it. PR is a pen recorder that receives the outputs of the rain gauge RFM and the thermometer TPM, and is configured to record the number of pulses within 5 minutes as the output from the rain gauge RFM, for example, every 5 minutes. The output is configured to record the temperature every 5 minutes.

MBH is a memory board holder that primarily processes measurement data from observation equipment such as rain gauge RFM and thermometer TPM and inputs it to the memory board described later.If these input values are analog values, they have the function of converting them to digital values. It also has functions for averaging and temporarily storing peak values within a unit time as necessary. This memory board holder MBH is configured to perform primary processing of input to facilitate storage on the memory board.

MB is a portable memory board with a clock that sends and receives input data by inserting it into the memory board holder MBH, and stores the input data with a time stamp attached. The MBR is a memory board reader that exchanges and reads stored information by inserting a memory board MB, and the PC is a personal computer that is connected to this memory board reader MBR and processes data.

Then, by inserting the memory board MB into the memory board reader MBR, the memory board MB is electrically connected to the memory board reader MBR, and the memory contents of the memory board MB are output to the memory board reader MBR at the same time. It is configured to be output to a computer PC.

Here, as mentioned above, this personal computer PC is a simple computer for personal use, and is generally suitable for offline data processing, but is not suitable for 24-hour continuous online control.

FIG. 2 is a block diagram of an embodiment showing extracted portions related to the memory board MB in the embodiment shown in FIG.

In FIG. 2, the same reference numerals as in FIG. 1 indicate corresponding parts. TER is a memory board
When the MB is inserted into the memory board holder MBH or memory board reader MBR, the memory board holder MBH or memory board reader
A power supply terminal that receives power from the MBR, and this power supply terminal TER is connected to the power supply unit PS.

And usually memory board MB is memory board holder MBH or memory board reader
When inserted into the MBR, the power supply part PS has a power terminal.
An external power supply is supplied through the TER, and the power associated with the operation of the memory board MB is covered by the external power supply.

By the way, this power supply part PS has memory protection for the semiconductor storage element RAM for memory and a standard clock ST.
A battery (not shown) is provided to drive the memory board MB, and the battery is configured to operate when the memory board MB is alone.

Note that when the memory board MB is inserted into the memory board holder MBH or memory board reader MBR and is operating, all parts of the memory board MB (CPU, ST, M, CU, Pd, Pt) operate at the same time. , an incomparably larger amount of power is required compared to when the memory board MB is used alone. Therefore, in this case, power is supplied from outside.

Pt is a light-receiving element made of a light-receiving diode, and Pd is a light-emitting element made of a light-emitting diode, which are photoelectric conversion elements for reception and transmission, respectively. And when the memory board MB is inserted into the memory board holder MBH or memory board reader MBR,
It is configured so that it approaches a photoelectric conversion element on the other side and performs spatial transmission. i.e. memory board MB and memory board holder
When exchanging data between MBHs or between memory board MB and memory board reader MBR, an optical space connection is configured.

The CU is a communication control unit that is connected to the light receiving element Pt and the light emitting element Pd, and exchanges information.This communication control unit CU is connected to the microprocessor CPU in the memory board MB, and receives commands from this microprocessor CPU. It is configured to be controlled by M is the standard clock for the time at that time.
This is a memory circuit that reads from the ST and stores the input information with a time stamp added. Furthermore, this standard clock
ST is connected to the microprocessor CPU.

Next, the operation of the embodiment shown in FIG. 1 will be explained with reference to FIG. 2.

First, the outputs of the observation equipment such as the rain gauge RFM and thermometer TPM are input to the memory holder MBH, where if these input values are analog, they are converted to digital values. Also, if necessary, it may be averaged or the peak value within a unit time may be temporarily stored. In other words, primary processing of the input is performed so that it can be easily stored on the memory board MB.

Input data that has been primarily processed by this memory board holder MBH is output to the inserted memory board MB at regular intervals. For example, an average value may be calculated at every predetermined sampling time for a changing analog input. Each time the memory board MB receives data from the memory board holder MBH, the memory board MB reads the current time from the standard clock ST and stores it along with the data.

Next, by inserting this memory board MB into the memory board reader MBR, this memory board MB is electrically and optically connected to the memory board reader MBR, and the memory contents of the memory board MB are output to the memory board reader MBR. At the same time, it is output to the personal computer PC.

i.e. memory board MB is memory board holder MBH or memory board reader MBR
When inserted into the power supply terminal TER shown in Figure 2.

Next, a method for calibrating the standard clock ST in the memory board MB will be explained.

First, insert the memory board MB into the memory board reader MBR and connect it to the personal computer PC.
When the correct current time is entered, this time information passes from the light emitting element (not shown) of the memory board reader MBR to the light receiving element Pt in the memory board MB, and the output of the light receiving element Pt is further transmitted to the communication control section.
The output of the communication control unit CU passes through the microprocessor CPU to calibrate the time of the standard clock ST.

In this way, the standard clock is stored inside the memory board MB.
The ST was installed because the time can be easily calibrated using the personal computer located in the center.

In addition, the memory board can be accessed from the personal computer PC through the memory board reader MBR.
A memory reset signal can also be implanted so that new data can be stored in the memory circuit M in the MB.

When the memory board MB whose time has been calibrated and the memory has been reset in this way is inserted into the memory board holder MBH, the holder number is first transferred from the light emitting element (not shown) on the memory board holder MBH side to the light receiving element Pt. sent. This holder number is then stored in the memory circuit M with the time stamp added thereto. When you later analyze the offline data on a personal computer, you will find out which holder the data is from.
This is to know when it was inserted into the memory board holder MBH.

Here, this memory board holder MBH is
As mentioned above, the measurement data from the observation equipment is primarily processed and stored in a memory board in an organized and organized form.
It is configured to output data to MB.
Also, the memory board MB is a memory board holder.
The configuration is such that each time data is received from the MBH, it is stored in the memory circuit M with a time stamp added thereto.
