　しかしながら、従来の技術では、ある第１の処理装置に接続された第１の機器の制御方法と、ネットワーク上の他の第２の処理装置に接続された第２の機器の制御方法とは異なっている。第１の処理装置は、第１の機器に直接アクセスする方法でプログラミング可能である。これに対し、第１の処理装置には、第２の機器を制御するために、間に介在するネットワークの通信プログラムを追加しなければ実現できない。 However, in the conventional technique, the control method of the first device connected to a certain first processing device is different from the control method of the second device connected to another second processing device on the network. ing. The first processing device is programmable in a way that directly accesses the first device. On the other hand, in order to control the second device, the first processing device cannot be realized without adding a network communication program interposed therebetween.
　特許文献１の技術は専用プロトコルを用いるため、ネットワーク間通信に専用のＩ／Ｆが必要となる。また、特許文献２の技術においても、車載の各機器間の通信には、専用のＩ／Ｆおよび専用プロトコルが必要となる。 Since the technology of Patent Document 1 uses a dedicated protocol, a dedicated I / F is required for communication between networks. Also in the technique of Patent Document 2, a dedicated I / F and a dedicated protocol are required for communication between each on-vehicle device.
　このように、第１の処理装置は第１の機器に対する制御を行うクローズドシステムであり、同様に第２の処理装置は第２の機器に対する制御を行うクローズドシステムであり、これらクローズドシステム間を跨いでの機器制御はネットワークの通信を間に介在させねばならず、通信処理のプログラムを別途必要とする。したがって、従来、自身の第１の処理装置がネットワーク上の第２の機器を制御するためには、プログラミングのステップ数が大幅に増えるという問題を生じた。 Thus, the first processing device is a closed system that controls the first device, and similarly, the second processing device is a closed system that controls the second device, and straddles between these closed systems. In the device control, network communication must be interposed between them, and a communication processing program is required separately. Therefore, conventionally, in order for the first processing apparatus of its own to control the second device on the network, there has been a problem that the number of programming steps is greatly increased.
　また、制御対象の機器を自身の第１の処理装置に接続されている第１の機器からネットワーク上の第２の機器に変更する場合、プログラムの変更工数が増大するという問題が生じた。 Also, when the control target device is changed from the first device connected to its own first processing device to the second device on the network, there is a problem that the number of program change man-hours increases.
　例えば、第１，第２の処理装置がそれぞれＣＰＵを備えた制御機器であり、互いにネットワーク接続されているとする。第１の処理装置は、第１の機器として監視カメラを制御する。第２の処理装置は、第２の機器として侵入検知器を制御する。そして、第１の処理装置によって、第２の機器（侵入検知器）を制御しようとする場合、この第２の機器は、第２の処理装置に固有のプログラムによって制御されているため、ネットワークの通信プログラムを追加し、かつ、第２の処理装置のプログラムにしたがったプログラム調整を行わなければならず、手間がかかった。 For example, it is assumed that the first and second processing devices are control devices each including a CPU and are connected to each other via a network. The first processing device controls the monitoring camera as the first device. The second processing device controls the intrusion detector as the second device. When the second processing device (intrusion detector) is to be controlled by the first processing device, the second device is controlled by a program unique to the second processing device. A communication program must be added and program adjustments must be made in accordance with the program of the second processing apparatus, which is troublesome.
　図７は、従来のネットワーク接続された他の機器の制御処理プログラム例を示す図である。図７の（ａ）に示すように、第１の処理装置Ａに接続された第１の機器Ｘへのアクセス（オープン、クローズ）については、通信にかかる処理を考慮せずに、少ない行数でプログラミングできる。 FIG. 7 is a diagram showing an example of a control processing program of another conventional device connected to the network. As shown in (a) of FIG. 7, for access (open, close) to the first device X connected to the first processing device A, the number of rows is small without considering communication processing. Can be programmed.
　しかしながら、図７の（ｂ）に示すように、第１の処理装置Ａが第２の機器Ｙへアクセス（オープン、クローズ）する場合には、第１の処理装置Ａと第２の処理装置Ｂとの間のネットワークの通信にかかる通信プログラムに追加行１００１ａ～１００１ｃ、および修正行１００２が必要となり、作業工数が増えてしまう。 However, as shown in FIG. 7B, when the first processing device A accesses (opens and closes) the second device Y, the first processing device A and the second processing device B. An additional line 1001a to 1001c and a correction line 1002 are required for a communication program related to network communication with each other, and the number of work steps increases.
　上述の説明では、第１の処理装置と第２の処理装置がネットワークを介して接続されることを前提に説明したが、これら第１，第２の処理装置がそれぞれ分散・マルチコアのＣＰＵ，共有メモリ等を備えた構成においても、ＣＰＵ間の通信において同様の問題を生じる。 The above description is based on the assumption that the first processing device and the second processing device are connected via a network. However, these first and second processing devices are respectively distributed and multi-core CPUs and shared. Even in a configuration including a memory or the like, the same problem occurs in communication between CPUs.

　図３は、実施の形態にかかる第１の処理装置から第２の機器へのアクセスの概要を説明する図である。第２の機器１２１（Ｙ）が所定の監視エリアの人などの侵入を監視する侵入検知器の例で説明する。 FIG. 3 is a diagram for explaining an overview of access from the first processing apparatus to the second device according to the embodiment. An example of an intrusion detector in which the second device 121 (Y) monitors the intrusion of a person or the like in a predetermined monitoring area will be described.
　はじめに、第１の処理装置（Ａ）１１０は、ＣＰＵ２０１がアプリケーション等のプログラム３０１を実行し、このプログラム３０１は、第２の機器１２１の監視情報の取得にかかる処理（図示の例ではＲｅａｄ関数をｃａｌｌ）を行い（ステップＳ３０１）、ｒｅａｄコマンドを発行する（ステップＳ３０２）。 First, in the first processing apparatus (A) 110, the CPU 201 executes a program 301 such as an application, and this program 301 performs processing related to acquisition of monitoring information of the second device 121 (in the illustrated example, a Read function is used). call) (step S301) and issue a read command (step S302).
　次に、プログラム３０１の下位層は、第２の機器１２１に対するコマンドを解釈し、第２の機器１２１の制御情報が示された処理テーブル３０２を参照し、第２の機器１２１の監視情報を取得するコマンドを発行する（ステップＳ３０３）。処理テーブル３０２は、第２の機器１２１が接続された第２の処理装置１２０に予め用意されるものであり、図２に示したＲＡＭ２０３上に作成され、記憶部２０４に保持できる。 Next, the lower layer of the program 301 interprets a command for the second device 121, refers to the processing table 302 in which the control information of the second device 121 is indicated, and obtains monitoring information of the second device 121. A command to be issued is issued (step S303). The processing table 302 is prepared in advance in the second processing device 120 to which the second device 121 is connected, and is created on the RAM 203 shown in FIG. 2 and can be held in the storage unit 204.
　ステップＳ３０３では、第１の処理装置１１０は、処理テーブル３０２を第２の処理装置１２０等から取得したものを参照する。また、第１の処理装置１１０は、ステップＳ３０３により発行されたコマンドを、汎用の通信Ｉ／Ｆを介して処理テーブル３０２に該当する第２の処理装置１２０に送信する。ここで、第１の処理装置１１０は、第２の機器１２１を制御するコマンドそのものを送信するのではなく、処理テーブル３０２の参照により、コマンドを解釈してこのコマンドに対応する制御の要求を送信する。第２の処理装置１２０は、処理テーブル３０２を有しており、処理テーブル３０２の参照により、第１の処理装置１１０から送信された要求に対応する制御を行うことができる。 In step S303, the first processing device 110 refers to the processing table 302 acquired from the second processing device 120 or the like. In addition, the first processing device 110 transmits the command issued in step S303 to the second processing device 120 corresponding to the processing table 302 via the general-purpose communication I / F. Here, the first processing device 110 does not transmit the command itself for controlling the second device 121 but interprets the command by referring to the processing table 302 and transmits a control request corresponding to this command. To do. The second processing device 120 has a processing table 302, and can perform control corresponding to the request transmitted from the first processing device 110 by referring to the processing table 302.
　第２の処理装置（Ｂ）１２０では、第１の処理装置１１０からのＲｅａｄコマンドを受け取り、Ｒｅａｄコマンドに対応して、第２の機器１２１から監視情報を取得し（ステップＳ３０４）、第１の処理装置１１０に対して監視情報を送付する（ステップＳ３０５）。 The second processing device (B) 120 receives the Read command from the first processing device 110, acquires monitoring information from the second device 121 in response to the Read command (Step S304), Monitoring information is sent to the processing device 110 (step S305).
　図４は、実施の形態にかかる制御プログラム例を示す図である。図４の（ａ）は、第１の処理装置１１０に接続されている第１の機器（Ｘ）１１１の制御プログラム例である。また、図４の（ｂ）は、第２の処理装置１２０に接続されている第２の機器１２１の制御プログラム例である。 FIG. 4 is a diagram illustrating an example of a control program according to the embodiment. 4A is an example of a control program for the first device (X) 111 connected to the first processing apparatus 110. FIG. FIG. 4B is an example of a control program for the second device 121 connected to the second processing device 120.
　図４の（ａ），（ｂ）のプログラムが示す制御内容は同じものとなる。このように、被制御対象（第１の機器１１１、第２の機器１２１）が自身（第１の処理装置１１０）に接続されている／いないにかかわらず、プログラム内容は同じとなる。したがって、プログラマは、第１の処理装置１１０のプログラムを作成する際に、第１の機器１１１、および第２の機器１２１について、第１の処理装置１１０と第２の処理装置１２０間の通信にかかる処理を意識することなく、プログラムを作成することができるようになる。 The control contents shown by the programs (a) and (b) in FIG. 4 are the same. As described above, the program contents are the same regardless of whether the controlled target (first device 111, second device 121) is connected to itself (first processing device 110). Therefore, when the programmer creates a program for the first processing device 110, the programmer communicates between the first processing device 110 and the second processing device 120 for the first device 111 and the second device 121. A program can be created without being aware of such processing.
　また、第１の処理装置１１０、第２の処理装置１２０に接続される第１の機器１１１、第２の機器１２１の故障や機能変更等によるハードウェアの変更が生じても、処理テーブル３０２を変更するだけで、図４に示したプログラム（アプリケーション層のソフトウェア）の変更は発生しない。 Further, even if a hardware change occurs due to a failure or a function change of the first device 111 or the second device 121 connected to the first processing device 110 or the second processing device 120, the processing table 302 is stored. The program (application layer software) shown in FIG. 4 is not changed only by the change.
　図５は、実施の形態にかかる第１の処理装置によって第２の機器にアクセスするための具体例を説明する図である。この例では、第２の機器１２１が接続された第２の処理装置１２０は、起動時にプログラム５０１が上記の処理テーブル３０２として関数呼び出しテーブル５０２を作成する。なお、関数呼び出しテーブル５０２は、プログラム５０１の起動時に限らず、任意のタイミングで作成してもよく、手作業で作成したものを外部から入力する構成としてもよい。 FIG. 5 is a diagram for explaining a specific example for accessing the second device by the first processing apparatus according to the embodiment. In this example, when the second processing device 120 connected to the second device 121 is activated, the program 501 creates the function call table 502 as the processing table 302 described above. The function call table 502 is not limited to when the program 501 is started, but may be created at an arbitrary timing, or may be configured to be input manually from outside.
　このプログラム５０１には、起動時に関数呼び出しテーブル５０２を作成する処理と、第２の機器１２１の監視情報を取得する処理（ｒｅａｄＰｏｒｔ）と、読み出した監視情報に対して所定の関数演算等の処理と、が記述（設定）されている。 The program 501 includes a process for creating a function call table 502 at startup, a process for obtaining monitoring information of the second device 121 (readPort), a process for performing a predetermined function operation on the read monitoring information, and the like. Are described (set).
　関数呼び出しテーブル５０２は、第２の機器１２１のＩＤ（ＩＤ１）と、この第２の機器１２１が接続された第２の処理装置１２０のポートのアドレスからなる。この例では、ＩＤ１には、第２の機器１２１から監視情報を読み出すためのｒｅａｄＰｏｒｔのアドレスが設定されている。このほか、図３に示したように、ＩＤ別に書き込み（Ｗｒｉｔｅ）、起動（Ｓｔａｒｔ）、停止（Ｓｔｏｐ）等の制御機能をそれぞれ設定しておくことができる。 The function call table 502 includes the ID (ID1) of the second device 121 and the address of the port of the second processing device 120 to which the second device 121 is connected. In this example, the ID of the read port for reading the monitoring information from the second device 121 is set in ID1. In addition, as shown in FIG. 3, control functions such as writing (Write), starting (Start), and stopping (Stop) can be set for each ID.
　関数呼び出しテーブル５０２の設定は、図５に示したように「ｒｅａｄＰｏｒｔ」のような文字列に限らず、ポートを読む旨を示す「１００１」のような数値列としてもよい。 The setting of the function call table 502 is not limited to a character string such as “readPort” as shown in FIG. 5, but may be a numerical string such as “1001” indicating that a port is read.
　通信処理タスク５０３は、ネットワーク１３０に対する（第１の処理装置１１０との間の）通信処理（受信および送信）を実行し、第１の処理装置１１０から第２の機器１２１に対する要求時には、該当するＩＤを用いた関数呼び出しテーブル５０２を検索し、要求に対応したプログラム５０１の関数演算を実行する。 The communication processing task 503 executes communication processing (reception and transmission) with respect to the network 130 (with respect to the first processing device 110), and is applicable when the first processing device 110 requests the second device 121. The function call table 502 using the ID is searched, and the function operation of the program 501 corresponding to the request is executed.
　以下、実施の形態にかかる第１の処理装置から第２の機器へのアクセスを行うための手順を順に説明する。はじめに、第２の処理装置１２０のプログラム５０１が起動すると、関数呼び出しテーブル５０２を作成する（ステップＳ５０１）。 Hereinafter, a procedure for accessing the second device from the first processing apparatus according to the embodiment will be described in order. First, when the program 501 of the second processing device 120 is activated, the function call table 502 is created (step S501).
　この際、プログラム５０１は、第２の処理装置１２０に接続されている第２の機器１２１の接続ポートを検出し、監視情報を読み出す機能のＩＤにｒｅａｄＰｏｒｔのアドレスを関連付けた設定を関数呼び出しテーブル５０２に作成する。同様に、第２の処理装置１２０が実行可能な制御（関数演算等）の機能について、所定のＩＤ（図示の例ではＩＤ２）を関数呼び出しテーブル５０２に設定する。 At this time, the program 501 detects the connection port of the second device 121 connected to the second processing device 120, and sets the function call table 502 to associate the readPort address with the ID of the function for reading the monitoring information. To create. Similarly, a predetermined ID (ID2 in the illustrated example) is set in the function call table 502 for the control (function calculation or the like) function that can be executed by the second processing device 120.
　そして、第１の処理装置１１０は、第２の処理装置１２０が作成した関数呼び出しテーブル５０２を任意のタイミングで取得する。関数呼び出しテーブル５０２の取得タイミングは、第２の機器１２１の機能、およびこの第２の機器１２１が接続されている第２の処理装置１２０の所在等を把握している場合には、第１の処理装置１１０が直接、第２の処理装置１２０にアクセスして取得する。 Then, the first processing device 110 acquires the function call table 502 created by the second processing device 120 at an arbitrary timing. The acquisition timing of the function call table 502 is the first timing when the function of the second device 121 and the location of the second processing device 120 to which the second device 121 is connected are known. The processing device 110 directly accesses the second processing device 120 for acquisition.
　これに限らず、第２の処理装置１２０がネットワーク１３０上に関数呼び出しテーブル５０２を公開している場合には、この公開された関数呼び出しテーブル５０２を参照した第１の処理装置１１０のうち、第２の機器１２１の制御を所望する（監視情報を取得要求する）第１の処理装置１１０が第２の処理装置１２０にアクセスして取得する構成とすることもできる。 Not limited to this, when the second processing device 120 publishes the function call table 502 on the network 130, the first processing device 110 that refers to the published function call table 502 includes the first processing device 110. The first processing device 110 that desires to control the second device 121 (requests to acquire monitoring information) may access and acquire the second processing device 120.
　この後、第１の処理装置１１０が第２の処理装置１２０に対して、第２の機器１２１の監視情報を取得する制御を行ったとする（ステップＳ５０２）。例えば、第１の処理装置１１０のプログラム３０１が第２の機器１２１の監視情報の取得にかかる処理（ＯｂｊＹ．ｒｅａｄＤａｔａ（））を実行する。 Thereafter, it is assumed that the first processing device 110 performs control to acquire the monitoring information of the second device 121 with respect to the second processing device 120 (step S502). For example, the program 301 of the first processing device 110 executes a process (ObjY.readData ()) related to acquisition of monitoring information of the second device 121.
　この場合、第１の処理装置１１０のプログラム３０１は、第２の機器１２１に対するｒｅａｄコマンド（ｒｅａｄＤａｔａ（））を発行する（ステップＳ５０３）。そして、プログラム３０１の下位層は、第２の機器１２１に対するコマンドを解釈し、第２の処理装置１２０から取得しておいた関数呼び出しテーブル５０２を参照し、第２の機器１２１の監視情報の取得に該当する識別子ＩＤ１を指定して、第２の機器１２１の監視情報を取得するコマンド（ｒｅａｄＰｏｒｔ（他））に対応する要求ＩＤ１を第２の処理装置１２０に送信する（ステップＳ５０４）。他とは、他の処理装置のポートを示す。 In this case, the program 301 of the first processing device 110 issues a read command (readData ()) to the second device 121 (step S503). Then, the lower layer of the program 301 interprets a command for the second device 121, refers to the function call table 502 acquired from the second processing device 120, and acquires monitoring information of the second device 121. The request ID1 corresponding to the command (readPort (other)) for acquiring the monitoring information of the second device 121 is transmitted to the second processing device 120 by designating the identifier ID1 corresponding to (Step S504). Other indicates a port of another processing apparatus.
　ここで、第１の処理装置１１０は、第２の処理装置１２０に対して第２の機器１２１の制御のコマンドそのものを送信するのではなく、関数呼び出しテーブル５０２の参照により、制御内容を含む識別子ＩＤだけを送信すればよいため、送信するデータ量を削減できる。 Here, the first processing device 110 does not transmit the control command itself of the second device 121 to the second processing device 120, but by referring to the function call table 502, an identifier including the control content. Since only the ID needs to be transmitted, the amount of data to be transmitted can be reduced.
　図６は、組み込み機器におけるプログラムの作成例を示す図である。実施の形態の第１の処理装置１１０および第２の処理装置１２０は、組み込み機器、例えば、上記の監視カメラや侵入検知器、リモコンやデジカメ、ＩＣレコーダ、車載装置、医療機器等、用途（動作）が限定された特定用途の機器の処理部として機能する。 FIG. 6 is a diagram showing an example of creating a program in an embedded device. The first processing device 110 and the second processing device 120 according to the embodiment are used for embedded devices such as the above-described monitoring cameras and intrusion detectors, remote controllers and digital cameras, IC recorders, in-vehicle devices, and medical devices. ) Functions as a processing unit of a specific application device.
　図６に示すプログラム６００は、クラスの定義６０１に基づき、第１の処理装置１１０の制御ソフト１のオブジェクト６０２と、コマンド６０３が定義される。オブジェクト６０２の機器Ａ（第１の機器１１１）は、自コンピュータ（第１の処理装置１１０）上にあることを示し、ＯｂｊＡは、内部のフラグ（ｆｌｇ）に自コンピュータの情報をセットする。オブジェクト６０２の機器Ｙ（第２の機器１２１）は、他コンピュータ（第２の処理装置１２０）上にあることを示し、ＯｂｊＹは、内部のフラグ（ｆｌｇ）に他コンピュータの情報をセットする。 The program 600 shown in FIG. 6 defines an object 602 and a command 603 of the control software 1 of the first processing apparatus 110 based on the class definition 601. The device A (first device 111) of the object 602 indicates that it is on its own computer (first processing device 110), and ObjA sets its own computer information in an internal flag (flg). The device Y (second device 121) of the object 602 indicates that it is on another computer (second processing device 120), and ObjY sets the information of the other computer in an internal flag (flg).
　そして、プログラム３０１は、読み出し（ｒｅａｄＤａｔａ）のコマンド６０３について、自コンピュータ（第１の処理装置１１０）に対するものであれば、指定の自インターフェース（Ｉ／Ｏポート）からデータをｒｅａｄしてその値をリターンする。また、他コンピュータ（第２の処理装置１２０）に対するものであれば、該当する第２の処理装置１２０と会話して、返された値をリターンする。 The program 301 reads data from the specified own interface (I / O port) if the read command 603 is for the own computer (first processing device 110), and sets the value. Return. Further, if it is for another computer (second processing device 120), it talks with the corresponding second processing device 120 and returns the returned value.
　図５に戻り説明すると、第２の処理装置１２０は、通信処理タスク５０３が第１の処理装置１１０からの要求ＩＤ１を受信する（ステップＳ５０５）。通信処理タスク５０３は、関数呼び出しテーブル５０２を参照し（ステップＳ５０６）、プログラム５０１に識別子ＩＤ１に対応する関数（ｒｅａｄＰｏｒｔ）を実行させる（ステップＳ５０７）。 Returning to FIG. 5, the second processing device 120 receives the request ID 1 from the first processing device 110 by the communication processing task 503 (step S505). The communication processing task 503 refers to the function call table 502 (step S506), and causes the program 501 to execute a function (readPort) corresponding to the identifier ID1 (step S507).
　この後、第２の処理装置１２０は、プログラム５０１がＩＤ１に対応して、Ｉ／Ｏポート読出処理を行い、該当する第２の機器１２１の監視情報を読み出し（ｒｅａｄＰｏｒｔ）、通信処理タスク５０３に返す（ステップＳ５０８）。 Thereafter, the second processing apparatus 120 performs I / O port reading processing in response to the program 501 corresponding to ID1, reads the monitoring information of the corresponding second device 121 (readPort), and sends it to the communication processing task 503. Return (step S508).
　そして、第２の処理装置１２０は、通信処理タスク５０３がｒｅａｄＰｏｒｔの結果、読み出した第２の機器１２１の監視情報を第１の処理装置１１０に送信する（ステップＳ５０９）。 Then, the second processing device 120 transmits the monitoring information of the second device 121 that has been read as a result of the read port of the communication processing task 503 to the first processing device 110 (step S509).
　第１の処理装置１１０は、プログラム３０１が発行したｒｅａｄＰｏｒｔ（他）の返答として第２の機器１２１から送信された監視情報をｒｅａｄＤａｔａ（）に変換し（ステップＳ５１０）、第２の機器１２１の監視情報の取得にかかる処理（ＯｂｊＹ．ｒｅａｄＤａｔａ（））の結果として、対応する第２の機器１２１の監視情報を取得する（ステップＳ５１１）。 The first processing device 110 converts the monitoring information transmitted from the second device 121 as a response to readPort (other) issued by the program 301 into readData () (step S 510), and monitors the second device 121. As a result of the process related to information acquisition (ObjY.readData ()), the monitoring information of the corresponding second device 121 is acquired (step S511).
　上記処理によれば、第１の処理装置１１０は、自装置内の処理であるか第２の処理装置１２０の処理であるかを、プログラム３０１が指定する引数（アクセス対象名）によって切り分ける。この際、外部（第２の処理装置１２０）へのアクセスについては、予め取得した関数呼び出しテーブル５０２を参照し、該当する第２の処理装置１２０にアクセスする。 According to the above processing, the first processing device 110 determines whether the processing is the processing in the own device or the processing of the second processing device 120 according to the argument (access target name) specified by the program 301. At this time, for access to the outside (second processing device 120), the function calling table 502 acquired in advance is referred to and the corresponding second processing device 120 is accessed.
　また、第２の処理装置１２０の通信処理タスク５０３と関数呼び出しテーブル５０２は、ソフトウェア実行に限らず、ハードウェアチップを用いて構成することもできる。 Further, the communication processing task 503 and the function call table 502 of the second processing device 120 can be configured not only by software execution but also by using a hardware chip.
　また、上記の関数呼び出しテーブル５０２は、上述したように、第１の処理装置１１０が取得するに限らず、第２の処理装置１２０がネットワーク１３０上に公開する構成とすることもできる。そして、関数呼び出しテーブル５０２が示す、第２の機器１２１の機能（Ｒｅａｄ，Ｗｒｉｔｅ，Ｓｔａｒｔ，Ｓｔｏｐ）は、ネットワーク１３０上の任意の第１の処理装置１１０によって取得し、制御（使用）できるようになる。 Further, as described above, the function call table 502 is not limited to being acquired by the first processing device 110, but may be configured to be disclosed on the network 130 by the second processing device 120. The function (Read, Write, Start, Stop) of the second device 121 indicated by the function call table 502 can be acquired and controlled (used) by any first processing device 110 on the network 130. Become.
　すなわち、第１の処理装置１１０は、関数呼び出しテーブル５０２を取得することにより、第２の処理装置１２０に接続された第２の機器１２１の機能を知ることができ、第１の処理装置１１０は、ネットワーク１３０の通信方式（手順）を隠蔽して第２の処理装置１２０に接続された第２の機器１２１を制御できるようになる。 That is, the first processing apparatus 110 can know the function of the second device 121 connected to the second processing apparatus 120 by acquiring the function call table 502, and the first processing apparatus 110 The second device 121 connected to the second processing device 120 can be controlled while hiding the communication method (procedure) of the network 130.
　これにより、第１の処理装置１１０（第１の機器１１１）に対して、第２の処理装置１２０（第２の機器１２１）が同一の部屋内や異なる場所に設置された場合においても、この設置場所に限定されず、第２の機器１２１を制御できるようになる。 Thus, even when the second processing device 120 (second device 121) is installed in the same room or in a different place with respect to the first processing device 110 (first device 111), The second device 121 can be controlled without being limited to the installation location.
　例えば、同一の部屋内に設けた異なる機能の第１の機器１１１（例えば監視カメラ）と、第２の機器１２１（例えば人体検知器）の異なる監視機能を第１の処理装置１１０により制御できるようになる。一方、第１の処理装置１１０で処理できない演算を第１の処理装置１１０の制御によって遠隔地の第２の処理装置１２０により演算処理できるようになる。 For example, the first processing device 110 can control different monitoring functions of a first device 111 (for example, a monitoring camera) and a second device 121 (for example, a human body detector) having different functions provided in the same room. become. On the other hand, operations that cannot be processed by the first processing device 110 can be processed by the second processing device 120 at a remote location under the control of the first processing device 110.
　さらに、関数呼び出しテーブル５０２は、ネットワーク１３０上のサーバに保持しておくこともでき、複数の第２の処理装置１２０毎の関数呼び出しテーブル５０２として保持できる。これにより、所定の機能を要求する第１の処理装置１１０は、サーバへのアクセスによって該当する機能（第２の機器１２１）を容易に検索することができ、また、第２の機器１２１が接続された第２の処理装置１２０へのアクセスを容易に行えるようになる。 Further, the function call table 502 can be held in a server on the network 130, and can be held as the function call table 502 for each of the plurality of second processing devices 120. Accordingly, the first processing device 110 that requests a predetermined function can easily search for the corresponding function (second device 121) by accessing the server, and the second device 121 is connected. The access to the second processing apparatus 120 thus made can be easily performed.
　上記実施の形態によれば、第１の処理装置および第２の処理装置のＣＰＵやＯＳに依存せず、互いに自処理装置あるいは他処理装置に接続されている第１の機器および第２の機器をネットワーク接続の有無に関係なく簡単に制御できるようになる。また、自処理装置にないメモリのリード／ライトや、関数実行についても同様に行えるようになる。したがって、第１の処理装置と第２の処理装置は、ネットワーク接続されたものに限らず、同一機器内での異なるＣＰＵ間通信についても同様に適用することができる。 According to the above embodiment, the first device and the second device connected to the own processing device or another processing device without depending on the CPU or OS of the first processing device and the second processing device. Can be easily controlled with or without network connection. In addition, memory read / write and function execution that are not in the processing apparatus can be performed in the same manner. Therefore, the first processing device and the second processing device are not limited to those connected to the network, and can be similarly applied to communication between different CPUs in the same device.
　これにより、第１の処理装置は、自処理装置に接続された第１の機器に対するクローズド制御に限らず、ネットワーク等を介して第２の処理装置に接続された第２の機器についても、通信（プロトコル）を意識せずに制御でき、プログラム作成についても通信を意識せずに作成できるため、プログラム作成を容易に行えるようになる。すなわち、第１の処理装置は、間に介在するネットワークの通信プログラムや専用Ｉ／Ｆを追加せずとも第２の機器を制御できるようになる。 Thereby, the first processing device is not limited to the closed control for the first device connected to the own processing device, but also communicates with the second device connected to the second processing device via a network or the like. Since it is possible to control without being aware of (protocol) and to create a program without being aware of communication, it becomes easy to create a program. That is, the first processing apparatus can control the second device without adding a network communication program or a dedicated I / F interposed therebetween.
　関数呼び出しテーブルは、第２の処理装置に接続された第２の機器が故障や仕様変更などでの交換や、追加の場合に更新される。これにより、第２の機器の機能が変更された場合であっても、第１の処理装置は、関数呼び出しテーブルを参照するだけで、所望する第２の機器の制御を行える。加えて、第２の機器が交換等されてもプログラム変更を不要にできる。 The function call table is updated when the second device connected to the second processing device is replaced or added due to a failure or specification change. Thereby, even if the function of the second device is changed, the first processing device can control the desired second device only by referring to the function call table. In addition, even if the second device is replaced, the program change can be made unnecessary.
　そして、特定用途の機能を有する組み込み機器においても、他の機器に対する制御を行って機能拡張が行えるようになる。また、汎用の情報処理装置においても所望する機能の機器に対する制御を容易に行えるようになる。具体的には、ＥＣＨＯＮＥＴやＡＵＴＯＳＡＲ等の規格に縛られず、専用Ｉ／Ｆや専用の通信プログラムを設けなくても、任意の他の機器に対する制御が可能となる。 And even in an embedded device having a function for a specific purpose, the function can be expanded by controlling other devices. Also, a general-purpose information processing apparatus can easily control a device having a desired function. Specifically, it is not limited to standards such as ECHONET and AUTOSAR, and any other device can be controlled without providing a dedicated I / F or a dedicated communication program.
　以上のように、本発明は、自処理装置に接続された機器以外の他の機器を制御する各種処理装置、例えば、特定用途の機能を有する組み込み機器や汎用の情報処理装置、およびこれらのソフトウェア開発に有用である。 As described above, the present invention provides various processing devices that control devices other than the devices connected to the processing device, for example, embedded devices having general-purpose functions, general-purpose information processing devices, and software thereof. Useful for development.
