[Problems to be solved by the invention]
However, in the seismometer management system, when a problem occurs in a part of the seismometer setting program, or when a part of the seismometer setting program is changed, an operator goes to the seismometer installation site and The setting program is replaced with a storage unit such as a ROM in which a different setting program is stored, or the setting program is rewritten by directly connecting a terminal to the seismometer. That is, since it is necessary to go to the place where the seismometer is installed, there is a problem that it is extremely troublesome for workers.
In addition, the replacement work of the ROM and the like requires a long time because it is necessary to disassemble and reassemble the seismometer, and the rewriting work of the setting program also takes a long time to rewrite the entire setting program. That is, there is a problem that the earthquake observation cannot be performed for a long time regardless of whether the storage unit is replaced or the entire setting program is rewritten. In seismic observation, the state of the installation site must be continuously observed, and if the observation cannot be resumed promptly, it will hinder analysis of earthquake information.

[0015]
Each seismometer 100 includes a vibration detector 101 that detects earthquake vibration, an I / O interface unit 102 connected to the vibration detector 101, and an A / D conversion unit 103 connected to the I / O interface unit 102. And a CPU 104 connected to the A / D conversion unit 103. That is, vibration data based on acceleration detected by the vibration detector 101 due to vibration such as an earthquake is transmitted to the A / D conversion unit 103 as an analog acceleration signal via the I / O interface unit 102, and A / D conversion is performed. After being digitally converted by the unit 103, it is transmitted to the CPU 104.
[0016]
The seismometer 100 also has a communication port 105 connected to the CPU 104. The communication port 105 is connected to the communication line 200, and the earthquake information data is transmitted to the management terminal 300 via the communication line 200. The CPU 104 is connected to an EEPROM 106 and a RAM 107. The CPU 104 stores programs and data stored in the EEPROM 106 in the RAM 107 and executes various processes using the RAM 107 as a work area.
[0017]
Here, the EEPROM 106 stores a setting program 110 for processing vibration data detected by the vibration detector 101. That is, in this embodiment, the I / O interface unit 102, the A / D conversion unit 103, the CPU 104, the EEPROM 106, the RAM 107, and the like constitute main processing means, and vibration data detected by the vibration detector 101 is stored in the EEPROM 106 in advance. Processing is performed based on the stored setting program 110. The setting program 110 has a plurality of blocks divided for each function. In this embodiment, an I / O related block 111, an A / D related block 112, a numerical calculation related block 113, a data recording related block 114, a data transmission related block 115, a parameter related block 116, and the like are provided.
[0018]
Here, the I / O related block 111 is a part related to processing in the I / O interface unit 102 in the setting program 110.
The A / D related block 112 is a part related to processing in the A / D conversion unit 103 in the setting program 110.
The numerical calculation related block 113 is a part related to the numerical calculation processing of vibration data in the CPU 104 in the setting program 110.
The data recording related block 114 is a part related to the process of recording the vibration data in the RAM 107 in the setting program 110.
The data transmission related block 115 is a part related to the process of transmitting the vibration data to the management terminal 300 in the setting program 110.
The parameter related block 116 is a part related to parameters used when processing vibration data in the setting program 110.
[0019]
Further, the EEPROM 106 stores address data 117 related to address information of each related block 111 to 116 of the setting program 110. In addition, the EEPROM 106 stores a rewrite program 118 for rewriting the setting program 110.
[0020]
In the seismometer 100, by executing the rewriting program 118, when program data 301 corresponding to a part of the setting program 110 is transmitted from the management terminal 300 to the seismometer 100, a part of the setting program 110 of the EEPROM 106 is transmitted. Can be rewritten to the program data 301. That is, in the present embodiment, the CPU 104, the EEPROM 106, the RAM 107, etc. constitute program rewriting means.
[0021]
In the present embodiment, the program data 301 transmitted from the management terminal 300 to the seismometer 100 corresponds to at least one of the related blocks 111 to 116. Then, address data 302 corresponding to the program data 301 is transmitted from the management terminal 300 together with the program data 301.
[0022]
That is, on the seismometer 100 side, when the address data 302 is transmitted together with the program data 301, the setting program 110 stored in the EEPROM 106 is rewritten based on the address data 302.
[0023]
The EEPROM 106 also stores a backup program 119 for storing the rewritten portion of the setting program 110 before being rewritten in the RAM 107 as pre-rewriting data 107a when the setting program 110 is rewritten based on the rewriting program 118. Yes.
The EEPROM 106 also stores a rewrite determination program 120 for determining whether or not the setting program 110 rewritten by the rewrite program 118 is normal.
Further, the EEPROM 106 has a rewrite program 121 for rewriting the rewritten portion of the setting program 110 to the pre-rewrite data 117 a stored in the RAM 107 when it is determined that the setting program 110 is not normal by executing the rewrite determination program 120. It is remembered.
That is, in the present embodiment, the CPU 104, the EEPROM 106, the RAM 107, etc. constitute backup means, rewrite determination means, and program rewrite means.
[0024]
The rewriting operation of the setting program 110 of the seismometer 100 in the seismometer management system 1 configured as described above will be described with reference to the flowchart shown in FIG. The initial state in FIG. 2 is a state in which the seismometer 100 continuously processes vibration data based on the setting program 110.
[0025]
First, it is determined whether or not there is a change request for the setting program 110 from the management terminal 300 (step S1). In the present embodiment, whether or not there is a change request is determined by whether or not the program data 301 and the address data 302 are transmitted. If there is no change request in step S1, the rewriting operation of the setting program 110 is terminated.
[0026]
If there is a change request in step S1, it is determined whether to change a part or all of the setting program 110 (step S2). In the present embodiment, it is determined based on the address data 302 transmitted to the seismometer 100 whether to change part or all of the setting program 110.
[0027]
When a part of the setting program 110 is changed, a change address corresponding to the block to be changed of the setting program 110 is set based on the address data 302 (step S3), and rewriting of the setting program 110 is started (step S3). S4). When changing all of the setting program 110, rewriting of the setting program 110 is started without setting the change address (step S4).
[0028]
Next, it is determined whether or not the rewriting is completed (step S5). When the rewriting is completed, it is determined whether or not the rewritten setting program 110 is normal (step S6). When the rewritten setting program 110 is normal and the seismometer 1 operates normally, the rewritten setting program 110 is activated (step S7).
[0029]
Here, when the rewritten setting program 110 is not normal and the seismometer 1 does not operate, or when the seismometer 1 operates abnormally, the rewritten portion of the setting program 110 is stored in the RAM 107. The data before rewriting 107a is rewritten (step S8). Then, the setting program 110 in the state before rewriting is activated (step S9).
[0030]
As described above, according to the seismometer management system 1 of the present embodiment, when a problem occurs in a part of the setting program 110 of the seismometer 100 or a change needs to be made, the management terminal 300 changes to the seismometer 100. When the program data 301 is transmitted, a part of the setting program 110 is rewritten to this program data 301. Thereby, without working at the installation point of the seismometer 100, it is possible to eliminate some problems of the setting program 110, change the setting program 110, change the specifications of the seismometer 1, etc. The burden on workers can be reduced.
At this time, since a part of the setting program 110 is rewritten, the rewriting operation can be completed in a much shorter time than when the entire setting program 110 is rewritten. Therefore, since the trouble of the setting program 110 can be solved and changed in a short time, the seismic observation can be resumed promptly and the seismic observation is not hindered. Further, the management terminal 300 can confirm that the setting program 110 of the seismometer 100 has been rewritten via the communication line 200.
[0031]
Further, according to the seismometer management system 1 of the present embodiment, the setting program 110 is divided into a plurality of blocks 111 to 116, and the setting program 110 is rewritten based on the address data 117 associated with each of the blocks 111 to 116. Since it did in this way, the part to be rewritten of the setting program 110 can be searched easily and easily, so that the rewriting operation can be shortened.
Moreover, since each block 111-116 was divided according to function, it can rewrite for every function of a seismometer, and is very convenient. For example, when the I / O interface unit 102 or the A / D conversion unit 103 is replaced, the program data 301 related to the I / O related block 111 or the A / D related block 112 corresponding to this part of the setting program 110 is transmitted. do it. For example, when changing the parameters of the seismometer 100, the program data 301 relating to the parameter-related block 116 corresponding to this portion may be transmitted.
[0032]
Further, according to the seismometer management system 1 of the present embodiment, when the rewritten setting program 110 is not normal, the setting program 110 is in a state before being rewritten, and the setting program 110 continuously acquires vibration data. be able to.
Therefore, for example, when the communication state deteriorates during transmission from the management terminal 300 to the seismometer 100 and the program data 301 is transmitted in pieces, or when the transmitted program data 301 is inappropriate, the seismometer 100 Does not operate or the seismometer 100 does not operate abnormally, and does not hinder the acquisition of vibration data of the seismometer 100.
[0033]
In the above embodiment, the address data 302 is transmitted with the program data 301. However, only the program data 301 may be transmitted. In this case, the seismometer 100 may have a function of searching for a portion corresponding to the program data 301 in the setting program 110.
[0034]
In the embodiment, the setting program 110 is divided into a plurality of blocks 111 to 116 for each function. However, the way of dividing the blocks may not be based on the function. Furthermore, the setting program 110 does not have to be divided into a plurality of blocks, and it is needless to say that specific detailed structures and the like can be appropriately changed.
[0035]
【The invention's effect】
As described in detail above, according to the first aspect of the invention, it is possible to eliminate some problems in the setting program or change the setting program without working at the installation point of the seismometer. The specification can be changed and the burden on the worker can be reduced.
In addition, since the setting program can be resolved and changed in a short time, the earthquake observation can be resumed quickly, and there will be no hindrance to the earthquake observation. Further, the management terminal can confirm that the seismometer setting program has been rewritten via a communication line or the like.
Moreover, even if the rewritten setting program does not operate normally, the vibration data can be continuously acquired by the setting program, so that, for example, the communication state deteriorates during transmission from the management terminal to the seismometer. If the program data is sent in pieces, or if the transmitted program data is inappropriate, the seismometer will not operate or the seismometer will not operate abnormally. There is no hindrance to data acquisition.
[0036]
According to the invention of claim 2, in addition to the effect of claim 1, the setting program is divided into a plurality of blocks, and the setting program is rewritten based on the address data associated with each block. The rewriting part of the setting program can be easily and easily searched, and the rewriting operation can be further shortened.
