Description
この発明は、マイクロコンピュータ（以下、「マイコン」と称する。）を実装した土木工事機械器具において、前記マイコンに外部から個別情報を書込むことができるようにした土木工事機械器具に関するものである。
The present invention relates to a civil engineering machinery / equipment in which a microcomputer (hereinafter referred to as “microcomputer”) is mounted so that individual information can be written to the microcomputer from the outside.
従来、汎用マイコンを実装する土木工事用機械器具において、各機械器具についての個別情報（例えば製造番号）のマイコンへの書込は、通常、マイコンが基板に実装されて機械器具に搭載される前の状態（オフボード状態）で、各種プログラムの書込と同時に行われていた。
汎用マイコンへの各種プログラムの書込がオフボード状態で行われるのは、マイコンへのプログラム書込には高い電圧が要求されることから、マイコンを基板に実装した状態（オンボード状態）でプログラム書込を行おうとすると、そのための電源回路を基板に設ける必要があり、基板が大型化、複雑化し、コスト高となってしまうことを回避するためである。なお、オンボード状態のマイコンであっても、ＪＴＡＧ仕様のマイコンを用いれば、各種プログラムの書き込みは可能であるが、ＪＴＡＧ仕様のマイコンはピンが多く大型である上、その種類も少なく、汎用性に乏しい。
また、製造番号等の個別情報が各種プログラムの書込と同時に行われるのは、これらを別々にマイコンに書き込むとすると、二度手間となるためである。 Conventionally, in civil engineering machinery and equipment in which general-purpose microcomputers are mounted, writing of individual information (for example, serial numbers) for each machine and equipment into the microcomputer is usually performed before the microcomputer is mounted on the board and mounted on the machine and equipment. In this state (off-board state), it was performed simultaneously with the writing of various programs.
The reason why various programs are written to the general-purpose microcomputer in the off-board state is because high voltage is required to write the program to the microcomputer, so the program is performed with the microcomputer mounted on the board (on-board state). If writing is to be performed, it is necessary to provide a power supply circuit for the substrate on the substrate, so that the substrate is prevented from becoming larger and more complicated and costly. Even if it is an on-board microcomputer, if you use a JTAG microcomputer, you can write various programs. However, the JTAG microcomputer has many pins, is small, and has few types. It is scarce.
Further, the individual information such as the serial number is performed simultaneously with the writing of the various programs because it would be troublesome to write these separately into the microcomputer.

また、製造番号等の個別情報が各種プログラムの書込と同時に行われるのは、これらを別々にマイコンに書き込むとすると、二度手間となるためである。 Conventionally, in civil engineering machinery and equipment in which general-purpose microcomputers are mounted, writing of individual information (for example, serial numbers) for each machine and equipment into the microcomputer is usually performed before the microcomputer is mounted on the board and mounted on the machine and equipment. In this state (off-board state), it was performed simultaneously with the writing of various programs.

Further, the individual information such as the serial number is performed simultaneously with the writing of the various programs because it would be troublesome to write these separately into the microcomputer.
各種プログラムと製造番号などの個別情報とをオフボード状態で同時に書き込むと、最終製品として完成していない状態であるにもかかわらず最終製品の製造番号がマイコンに記憶された状態で生産ラインに流れるため、この製造番号を生産工程において管理する必要が生じる。マイコンに記録された製造番号を生産ラインで認識するために、個々のマイコンに製造番号を記載したシールなどを添付し、機械器具に装着する際に機械器具の製造番号と一致させる必要があり、作業が煩雑化している。また、例えば生産ラインで不具合が発生して最終製品として未完成のまま廃棄される場合などには、出荷される製品の製造番号に欠番が生じる等、製造番号の管理上の問題がある。
When various programs and individual information such as serial numbers are written simultaneously in an off-board state, the final product serial number flows to the production line in a state where the final product serial number is stored in the microcomputer even though it is not completed as a final product. Therefore, it is necessary to manage this serial number in the production process. In order to recognize the serial number recorded on the microcomputer in the production line, it is necessary to attach a sticker with the serial number to each microcomputer and match it with the serial number of the machine when attaching to the machine. Work is complicated. In addition, for example, when a problem occurs in the production line and the product is discarded as an unfinished product, there is a problem in management of the production number such as a missing number in the production number of the product to be shipped.
したがって、最終製品の製造番号などの個別情報は、製品完成時にマイコンに書き込むことが好ましいが、共通プログラムは組み込み前に多数のマイコンに同時に記録することが効率的である。
そこで、共通プログラムは一括して書き込み、最終製品の製造番号などの個別情報は、製品完成後、プログラムとは別々にマイコンに書き込むことが望まれる。 Therefore, it is preferable to write individual information such as the serial number of the final product in the microcomputer when the product is completed, but it is efficient to record the common program in many microcomputers simultaneously before incorporation.
Therefore, it is desirable to write the common program all together and write individual information such as the final product serial number to the microcomputer separately from the program after the product is completed.

マイコンに書き込まれる個別情報は土木工事機械の製造番号が代表的であるが、個々の機械を識別するための情報であればこれに限られるものではない。
The individual information written in the microcomputer is typically a civil engineering machine serial number, but is not limited to this as long as it is information for identifying individual machines.
この発明によれば、マイコンが実装された土木工事機械器具において、前記マイコンには共通プログラムとモード切替信号入力時に個別情報書き込みモードに切り替え個別情報の入力を可能にするモード切替手段とを記録し、土木工事機械器具の外面に露出して装着された端子がモード切替信号並びに個別情報を入力するためのポートに接続され、このポートを通じて土木機械器具に実装されたマイコンに個別情報を入力できるようにしたので、共通プログラムを予め一括して記録しておき、土木工事機械器具への装着後に個別に製造番号などの個別情報を記録することができる。
そして、上記のような構成としてあるので、モード切替信号及び個別情報の双方を共通のポートを用いてマイコンに入力することができ、モード切替信号がマイコンに入力されるとモード切替手段がこれを認識してマイコンのモードを個別情報書込モードに切り替えることができる。

The microcomputer records individual information presence / absence determining means for determining whether or not the individual information has already been written when the writing mode is switched, and overwriting of the individual information is prevented when the individual information has already been written. Thus, when individual information has already been written, different individual information is not overwritten by mistake.
マイコンに書き込まれる個別情報は、土木工事機械の製造番号としたので、土木工事機械器具の製造段階では製造番号をマイコンに記録する必要がなく、完成後に共通プログラムとは別々に製造番号を個別にマイコンに書き込むことができ、生産工程における製造番号管理が容易となる。
Since the individual information written in the microcomputer is the civil engineering machine serial number, there is no need to record the serial number in the microcomputer at the civil engineering machinery manufacturing stage, and the serial number is separately separated from the common program after completion. It can be written in a microcomputer, and serial number management in the production process becomes easy.

図２は、マイコン２に土木工事機械１の製造番号を書き込むためのプログラムのフローチャートである。
製造番号書込装置の端子と土木工事機械１の端子４とを接続し、製造番号書込装置及びマイコン２の電源を入れ、製造番号データ書込を開始すると、製造番号書込装置からマイコン２のモードを製造番号書込モードに切り替えるためのモード切替信号が送信される。
モード切替信号を受信したマイコン２はこれを識別して製造番号書込モードに切り替わり、製造番号書込用プログラムの実行を開始する。
製造番号書き込み用プログラムが開始されると、まず、マイコン２に既に製造番号が書き込まれていないかどうかを書込済み情報の有無によって判別する。既に書込済み情報を検出した場合には製造番号書込用プログラムは終了し、製造番号の上書きがされることはない。書込済み情報を検出しない場合には待機モードに移行し、製造番号書込装置から同期信号が送信されてくるのを待機する。
次いで、製造番号書込装置から同期信号が送信された後、製造番号データが送信され、ＥＥＰＲＯＭ２３に製造番号が書き込まれる。
ＥＥＰＲＯＭ２３に製造番号が書き込まれた後、書込済み情報がＥＥＰＲＯＭ２３に書き込まれると製造番号書き込み用プログラムが終了する。 FIG. 2 is a flowchart of a program for writing the manufacturing number of thecivil engineering machine 1 in the microcomputer 2.
When the terminal of the manufacturing number writing device and theterminal 4 of the civil engineering machine 1 are connected, the manufacturing number writing device and the microcomputer 2 are turned on, and the manufacturing number data writing is started, the microcomputer 2 starts from the manufacturing number writing device. A mode switching signal for switching the mode to the manufacturing number writing mode is transmitted.
Receiving the mode switching signal, themicrocomputer 2 identifies this and switches to the serial number writing mode, and starts executing the serial number writing program.
When the production number writing program is started, first, it is determined whether or not the production number has already been written in themicrocomputer 2 by the presence or absence of written information. If already written information is detected, the serial number writing program is terminated and the serial number is not overwritten. When the written information is not detected, the process shifts to the standby mode and waits for the synchronization signal to be transmitted from the serial number writing device.
Next, after a synchronization signal is transmitted from the serial number writing device, serial number data is transmitted, and the serial number is written in theEEPROM 23.
After the serial number is written in theEEPROM 23, when the written information is written in the EEPROM 23, the serial number writing program ends.

図３は、この発明の製造番号の書込みにおいて、マイコン２と製造番号書込装置との間で使用される信号データのタイミングを示す図である。
製造番号書込装置で製造番号の書込を開始すると、まず、マイコン２のモードを製造番号書込モードに切り替えるためのモード切替信号ＭＣｓが送信される。このモード切替信号ＭＣｓは、書込装置からの書き込み用に予め設定された特殊なパルス列である。
次いで、同期信号Ｓｙｎｃが送信され、続いて製造番号データ信号Ｄｓが送信されて、製造番号データがＥＥＰＲＯＭ２３に書き込まれる。
データ信号Ｄｓが多ビットにわたり長い場合には、同期信号Ｓｙｎｃ、データ信号Ｄｓの組み合わせを複数送出することも可能である。 FIG. 3 is a diagram showing the timing of signal data used between themicrocomputer 2 and the serial number writing device in the serial number writing of the present invention.
When the production number writing device starts writing the production number, first, a mode switching signal MCs for switching the mode of themicrocomputer 2 to the production number writing mode is transmitted. The mode switching signal MCs is a special pulse train preset for writing from the writing device.
Next, the synchronization signal Sync is transmitted, then the serial number data signal Ds is transmitted, and the serial number data is written in theEEPROM 23.
When the data signal Ds is long over many bits, a plurality of combinations of the synchronization signal Sync and the data signal Ds can be transmitted.

製造番号データＤｓが書き込まれた後、最後にデータ書込済み信号Ｆｓが送信されてマイコン２のポート３１を閉じる。
After the serial number data Ds is written, the data written signal Fs is finally transmitted and the port 31 of the microcomputer 2 is closed.
上記のように、マイコン２を製造番号書込モードに切り替えるモード切替信号を、製造番号書込装置から製造番号を書き込む際に送信するものとしたので、マイコン側でのスイッチ操作なしにマイコンのモードを切り替えることができる。
また、同期信号判別用信号ＳＤｓ、同期信号Ｓｓ、製造番号データＤｓを順に送信することとしたので、同期信号と製造番号データ信号とを一本のラインに乗せることができ、マイコン２のＩ／Ｏポート３の一のポートのみを用いて製造番号を書き込むことができる。 As described above, since the mode switching signal for switching themicrocomputer 2 to the serial number writing mode is transmitted when the serial number is written from the serial number writing device, the microcomputer mode can be switched without a switch operation on the microcomputer side. Can be switched.
Further, since the synchronization signal discrimination signal SDs, the synchronization signal Ss, and the production number data Ds are sequentially transmitted, the synchronization signal and the production number data signal can be put on one line, and the I / O of themicrocomputer 2 The serial number can be written using only one port of the O port 3.

この実施例のデータ転送方法では、一本のラインで送信又は受信の何れか一方通行でのみ転送できるので、製造番号書込装置からの送信のみで製造番号書込を行う場合に適している。
The data transfer method of this embodiment is suitable for writing a production number only by transmission from a production number writing device, because it can be transferred only by one-way transmission or reception on a single line.
図４はこの発明の第２の実施例の構成を示す図である。すなわち、製造番号書込装置からマイコン２に製造番号を書き込むだけでなく、この書込に用いられたラインと同じラインを利用して、マイコン２から製造番号書込装置と表示器とを一体とした装置に対して表示データ等を送信するようにしたものである。
この装置としては、この機能のプログラムを実行しているパーソナルコンピュータを使用することもでき、パーソナルコンピュータへデータを出力することもできる。 FIG. 4 is a diagram showing the configuration of the second embodiment of the present invention. That is, not only the serial number is written in themicrocomputer 2 from the serial number writing device, but also the serial number and the display unit are integrated from the microcomputer 2 by using the same line used for the writing. Display data or the like is transmitted to the device.
As this apparatus, a personal computer executing a program of this function can be used, and data can be output to the personal computer.

図５は、第２の実施例において用いられる信号データのタイミングを示す図である。
マイコン２の電源を投入すると、マイコン２のモードが初期状態としてデータ入力モードとなり、モード信号待ちの状態となる。次に、受信モード信号ＲＭｓを製造番号書込装置から受信することにより、製造番号書込モードとなる。
受信モード信号ＲＭｓを送信した製造番号書込装置は、同期信号ＳｙｎｃＡ、製造番号データＤｓを順次送信する。ここで、一定時間経過してもマイコン２が同期信号ＳｙｎｃＡを受信しない場合には、マイコン２の製造番号書込モードが解除され、初期状態としてのデータ入力モードとなる。
マイコン２から信号を送信する場合には、マイコン２は送信モード信号ＳＭｓを受信する。送信モード信号ＳＭｓを送信した表示器は、マイコン２からの送信信号の受信を待機し、マイコン２から送信される同期信号ＳｙｎｃＢ、表示データなどのデータ信号ＳＤｓを順次受信する。データ信号ＳＤｓを受信した表示器は、受信したデータ信号ＳＤｓの内容に従って、例えばマイコン２に書き込まれた製造番号が表示される。 FIG. 5 is a diagram showing the timing of signal data used in the second embodiment.
When the power source of themicrocomputer 2 is turned on, the mode of the microcomputer 2 is set to the data input mode as an initial state, and the mode signal is waited. Next, the serial number writing mode is entered by receiving the reception mode signal RMs from the serial number writing device.
The serial number writing device that has transmitted the reception mode signal RMs sequentially transmits a synchronization signal SyncA and serial number data Ds. Here, if themicrocomputer 2 does not receive the synchronization signal SyncA even after a predetermined time has elapsed, the serial number writing mode of the microcomputer 2 is canceled and the data input mode is set as the initial state.
When transmitting a signal from themicrocomputer 2, the microcomputer 2 receives the transmission mode signal SMs. The display that has transmitted the transmission mode signal SMs waits for reception of the transmission signal from the microcomputer 2 and sequentially receives the synchronization signal SyncB and the data signal SDs such as display data transmitted from the microcomputer 2. The display that has received the data signal SDs displays, for example, the serial number written in the microcomputer 2 in accordance with the contents of the received data signal SDs.
マイコン２の電源を投入すると、マイコン２のモードが初期状態としてデータ入力モードとなり、モード信号待ちの状態となる。次に、受信モード信号ＲＭｓを製造番号書込装置から受信することにより、製造番号書込モードとなる。
受信モード信号ＲＭｓを送信した製造番号書込装置は、同期信号ＳｙｎｃＡ、製造番号データＤｓを順次送信する。ここで、一定時間経過してもマイコン２が同期信号ＳｙｎｃＡを受信しない場合には、マイコン２の製造番号書込モードが解除され、初期状態としてのデータ入力モードとなる。
マイコン２から信号を送信する場合には、マイコン２は送信モード信号ＳＭｓを受信する。送信モード信号ＳＭｓを送信した表示器は、マイコン２からの送信信号の受信を待機し、マイコン２から送信される同期信号ＳｙｎｃＢ、表示データなどのデータ信号ＳＤｓを順次受信する。データ信号ＳＤｓを受信した表示器は、受信したデータ信号ＳＤｓの内容に従って、例えばマイコン２に書き込まれた製造番号が表示される。 FIG. 5 is a diagram showing the timing of signal data used in the second embodiment.
