Description

保安情報書換えシステム及び地上子Security information rewriting system and ground unit
　本発明は、保安情報書換えシステムに関し、特に鉄道の保安設備の保安情報の書き換えを遠隔地から行い得るようにした保安情報書換えシステム及び地上子に係るものである。 The present invention relates to a security information rewriting system, and more particularly to a security information rewriting system and a ground unit that can rewrite the safety information of a railroad safety facility from a remote location.
　従来、鉄道の保安設備としての地上子の設定電文（保安情報）の書き換えは、情報伝達媒体としての電波により外部から非接触で与えられる電文情報を受信可能な受信手段の機能を有する地上子の送信コイルを介して行うようになっていた（例えば、特許文献１参照）。 Conventionally, rewriting of a set telegram (security information) of a ground unit as a railroad security facility is a function of a reception unit capable of receiving telegram information given from the outside by a radio wave as an information transmission medium. This is performed via a transmission coil (see, for example, Patent Document 1).
特開平８－１１７１８号公報JP-A-8-11718
　しかし、特許文献１には、外部から送信装置を使用して上記送信コイルに対して設定電文情報を送信することについて開示されているものの、送信装置の詳細については明らかにされていない。 However, Patent Document 1 discloses that the set message information is transmitted from the outside to the transmission coil using a transmission device, but details of the transmission device are not disclosed.
　一般に、地上子の設定電文情報の書き換えは、電文情報の送信可能な電文書込み装置を携帯し、現場において作成された設定電文情報、又は電文書込み装置に予め作成して保存された設定電文情報を地上子に送信して行われる。 In general, rewriting of the telegram setting message information is carried by carrying a telegram embedding device capable of transmitting telegram information, and setting teletext information created in the field or pre-created and saved in the telegram embedding device. It is sent to the ground unit.
　しかしながら、この場合、地上子の電文を書き換えようとするときには、該当地上子の設置場所まで出向かなければならず、遠隔地の地上子や複数の地上子の電文の書き換えを行う際には、電文書換え作業が容易でなかった。 However, in this case, when trying to rewrite the message of the ground unit, it is necessary to go to the installation site of the corresponding ground unit, and when rewriting the message of a remote ground unit or multiple ground units, Electronic document change work was not easy.
　そこで、本発明は、このような問題点に対処し、鉄道の保安設備の保安情報の書き換えを遠隔地から行い得るようにした保安情報書換えシステム及び地上子を提供することを目的とする。 Therefore, an object of the present invention is to provide a security information rewriting system and a ground unit that can cope with such problems and can rewrite the safety information of railway security equipment from a remote location.
　上記目的を達成するために、本発明による保安情報書換えシステムは、設定しようとする新情報を基地局から鉄道の保安設備に向けて送信し、前記保安設備に既保存の旧情報を前記新情報に書き換え得るように構成したものである。 In order to achieve the above object, a security information rewriting system according to the present invention transmits new information to be set from a base station to a railroad security facility, and the old information already stored in the security facility is transmitted to the new information. It can be rewritten as follows.
　また、本発明による地上子は、設定するために基地局から送信された新電文情報を一時的に保存する第１の記憶部と、内蔵された第２の記憶部に既保存の旧電文情報を、前記第１の記憶部に保存された新電文情報に書き換えるタイミングを制御する制御装置と、を備えたものである。 Further, the ground unit according to the present invention includes a first storage unit that temporarily stores new telegram information transmitted from the base station for setting, and old telegram information that is already stored in the built-in second storage unit. And a control device for controlling the timing of rewriting the new telegram information stored in the first storage unit.
　本発明によれば、保安情報の書き換えを、保安設備の設置場所まで出向くことなく、該保安設備から離れた基地局から保安情報を送信して行うことができる。したがって、保安設備としての例えば地上子の電文（保安情報）書換え作業を、地上子の設置現場まで出向くことなく遠隔地から容易に行うことができる。 According to the present invention, the security information can be rewritten by transmitting the security information from a base station away from the security facility without going to the installation site of the security facility. Therefore, for example, a teletext message (security information) rewriting work as a security facility can be easily performed from a remote location without going to the site where the ground unit is installed.

　次に、このように構成された保安情報書換えシステムの動作について説明する。
　基地局１は、電文情報を書き換えようとする地上子３を特定すると共に、該地上子３の設置位置情報とＣＢＴＣシステムを利用して取得した列車位置情報とに基づいて上記地上子３に接近中又は上記地上子３上に停車中の列車４を特定する。 Next, the operation of the security information rewriting system configured as described above will be described.
The base station 1 specifies the ground element 3 to rewrite the telegram information, and approaches the ground element 3 based on the installation position information of the ground element 3 and the train position information acquired using the CBTC system. A train 4 that is stopped inside or on the ground unit 3 is specified.
　上記列車４が特定されると、基地局１は、書き換えるために予め作成された新電文情報を当該列車４に向けて送信する。送信された新電文情報は、地上アンテナを介して又は直接、上記列車４の車上装置５に受信され、車上装置５に設けられた図示省略の記憶部に保存される。 When the train 4 is specified, the base station 1 transmits new telegram information created in advance for rewriting to the train 4. The transmitted new telegram information is received by the on-board device 5 of the train 4 via the ground antenna or directly and stored in a storage unit (not shown) provided on the on-board device 5.
　ここでは、先ず、上記特定された地上子３が、走行中の列車４に対して電文情報を送信し、列車４の運行を制御するものである場合について説明する。
　この場合、車上装置５は、車上子６と地上子３との間の電磁カップリング２ｂが開始されると、地上子３から第２の記憶部９に保存された電文情報を受信し、該電文情報に基づいて例えば速度照査パターンを生成し、該パターンを照査しながら走行速度を制御すると共に、上記記憶部に保存された新電文情報を地上子３に向けて送信する。 Here, first, a case will be described in which the identified ground element 3 transmits telegram information to the traveling train 4 to control the operation of the train 4.
In this case, when the electromagnetic coupling 2b between the vehicle upper element 6 and the ground element 3 is started, the on-board device 5 receives the telegram information stored in the second storage unit 9 from the ground element 3. Based on the message information, for example, a speed check pattern is generated, the running speed is controlled while checking the pattern, and the new message information stored in the storage unit is transmitted to the ground unit 3.
　一方、上記車上子６と地上子３との間の電磁カップリング２ｂが開始されると、地上子３側では、電文送受信制御装置１０により制御して第２の記憶部９に保存された電文情報（旧電文情報）を読み出し、送受信コイル７を介して車上装置５に送信すると共に、車上装置５から受信した新電文情報を第１の記憶部８に一時的に保存する。 On the other hand, when the electromagnetic coupling 2b between the vehicle upper element 6 and the ground element 3 is started, on the ground element 3 side, it is controlled by the message transmission / reception control device 10 and stored in the second storage unit 9. The telegram information (old telegram information) is read out and transmitted to the on-board device 5 via the transmission / reception coil 7, and the new telegram information received from the on-board device 5 is temporarily stored in the first storage unit 8.
　上記列車４の車上子６と地上子３との間の電磁カップリン２ｂが終了して予め定められた所定時間が経過すると、即ち、列車４が上記地上子３上を通過し終えると電文送受信制御装置１０の制御部１１は、第１の記憶部８に一時的に保存された新電文情報を読み出し、該新電文情報で第２の記憶部９に保存された旧電文情報を上書きし、第２の記憶部９の電文情報を新電文情報に書き換える。
　以降、後続の列車４は、地上子３から取得する上記新電文情報に基づいて運行が制御される。 When the electromagnetic coupling 2b between the vehicle upper 6 and the ground 3 of the train 4 ends and a predetermined time elapses, that is, when the train 4 finishes passing over the ground 3 The control unit 11 of the transmission / reception control device 10 reads the new message information temporarily stored in the first storage unit 8 and overwrites the old message information stored in the second storage unit 9 with the new message information. The message information in the second storage unit 9 is rewritten with new message information.
Thereafter, the operation of the subsequent train 4 is controlled based on the new telegram information acquired from the ground unit 3.
　なお、制御部１１は、新電文情報が正しいものか否か、又は送信相手先が正しいか否か等を確認するベリファイ機能を有している。したがって、制御部１１は、新電文情報に含まれる地上子番号と当該地上子３の地上子番号とを比較して第１の記憶部８に保存された新電文情報が当該地上子３に宛てたものであるか否かを判定したり、上記新電文情報が規格に従った正しい構文を有するものであるか否かを判定したりする。この場合、上記新電文情報が当該地上子３に宛てたものでないときや、規格に従った正しいデータでないと判定したときには、制御部１１は、この新電文情報を破棄すると共に誤送又はデータが正しくないことを示す応答データを第２の記憶部９に記憶する。そして、次の列車が当該地上子３上を通過する際に、第２の記憶部９から旧電文情報と共に上記応答データを車上装置５に送信する。これにより、上記応答データは、無線通信路２ａを介して車上装置５から基地局１に送信される。したがって、基地局１においては、データの誤りを訂正した正しい電文情報を改めて送信することができる。また、制御部１１は、第１の記憶部８から第２の記憶部９に新電文情報が正しく書き込めたか否かを、書込み後のデータと書込み前のデータとを比較して判定する。この場合、データの書き込みが正しく行われていないときには、制御部１１は、第１の記憶部８から第２の記憶部９への新電文情報の書込み動作を改めて実行する。 The control unit 11 has a verify function for confirming whether or not the new message information is correct or whether or not the transmission destination is correct. Therefore, the control unit 11 compares the ground element number included in the new telegram information with the ground element number of the ground element 3 and the new message information stored in the first storage unit 8 is addressed to the ground element 3. Or whether the new message information has a correct syntax according to the standard. In this case, when the new telegram information is not addressed to the ground unit 3 or when it is determined that the new telegram information is not correct data according to the standard, the control unit 11 discards the new telegram information and sends an erroneous transmission or data. Response data indicating that it is not correct is stored in the second storage unit 9. Then, when the next train passes on the ground unit 3, the response data is transmitted from the second storage unit 9 together with the old telegram information to the on-board device 5. Thereby, the response data is transmitted from the on-board device 5 to the base station 1 via the wireless communication path 2a. Therefore, in the base station 1, correct telegram information in which the data error is corrected can be transmitted again. Further, the control unit 11 determines whether or not the new message information has been correctly written from the first storage unit 8 to the second storage unit 9 by comparing the data after writing with the data before writing. In this case, when the data is not correctly written, the control unit 11 performs a new message information writing operation from the first storage unit 8 to the second storage unit 9 again.
　次に、上記特定された地上子３が、停車中の列車４に対して電文情報を送信し、列車４の運行を制御するものである場合について説明する。
　この場合、車上装置５は、車上子６と地上子３とが電磁カップリング２ｂしている間に、上記記憶部に一時的に保存された新電文情報を直下の地上子３に向けて送信する。 Next, a case will be described in which the identified ground element 3 transmits telegram information to the stopped train 4 to control the operation of the train 4.
In this case, the on-board device 5 directs the new telegram information temporarily stored in the storage unit to the directly below ground unit 3 while the vehicle unit 6 and the ground unit 3 are electromagnetically coupled 2b. To send.
　一方、地上子３側では、電文送受信制御装置１０により制御して車上装置５から受信した新電文情報を第１の記憶部８に一時的に保存する。その後、車上子６と地上子３とが電磁カップリング２ｂしている間に、電文送受信制御装置１０の制御部１１により制御して第１の記憶部８に一時的に保存された新電文情報を読み出し、該新電文情報で第２の記憶部９に保存された旧電文情報を上書きし、第２の記憶部９の電文情報を新電文情報に書き換える。 On the other hand, on the ground unit 3 side, the new message information received from the on-board device 5 under the control of the message transmission / reception control device 10 is temporarily stored in the first storage unit 8. Thereafter, while the vehicle upper element 6 and the ground element 3 are electromagnetically coupled 2b, the new electronic message that is temporarily stored in the first storage unit 8 under the control of the control unit 11 of the electronic message transmission / reception control device 10 The information is read, the old message information stored in the second storage unit 9 is overwritten with the new message information, and the message information in the second storage unit 9 is rewritten with the new message information.
　この場合、停車中の列車４は、第２の記憶部９に保存された新電文情報を直下の地上子３から停車中に取得し、その後の列車４の運行が制御されてもよく、又は、車上装置５の記憶部に保存された新電文情報に基づいて列車４の運行が制御されてもよい。なお、前述したように、制御部１１がベリファイ機能を有しているため、制御部１１は、受信した新電文情報の正誤を判定し、データに誤りがあるときには、その旨を直ちに基地局１に伝え、正しい電文情報を受け取ることができるようにしている。
　以降、後続の列車４は、地上子３から取得する上記新電文情報に基づいて運行が制御される。 In this case, the stopped train 4 may acquire new telegram information stored in the second storage unit 9 from the ground unit 3 immediately below, and the subsequent operation of the train 4 may be controlled. The operation of the train 4 may be controlled based on the new telegram information stored in the storage unit of the on-board device 5. As described above, since the control unit 11 has a verify function, the control unit 11 determines whether the received new message information is correct or incorrect. If there is an error in the data, the base station 1 immediately notifies that fact. In order to receive the correct telegram information.
Thereafter, the operation of the subsequent train 4 is controlled based on the new telegram information acquired from the ground unit 3.
　このように、本発明によれば、地上子３の電文の書き換えを、地上子３の設置場所まで出向くことなく、該地上子３から離れた基地局１から送信された電文情報により行うことができ、電文書換え作業が容易になる。また、無線通信により電文情報を送信して書き換える場合には、例えば既存のＣＢＴＣ無線式列車制御システムを利用して行うことができ、特別な地上設備を必要としない。したがって、保安情報書換えシステムの建設コストを低減することができる。 As described above, according to the present invention, rewriting of the telegram of the ground child 3 can be performed based on the telegram information transmitted from the base station 1 away from the ground child 3 without going to the place where the ground child 3 is installed.

In this case, the telegram information transmitted from the base station 1 to the rail 17 via the matching unit may be received by the antenna provided in the ground unit 3. Thereby, it is possible to easily change the electronic document of the ground unit 3 in the train line or the standby line, for example, with a low traveling frequency of the train 4.
　さらに、上記実施形態においては、基地局１から地上子３に向けた電文情報の送信を無線により行う場合について述べたが、本発明はこれに限られず、基地局１と地上子３とを有線により接続し、該有線を介して電文情報を送信してもよい。この場合も、地上子３の電文の書き換えを、地上子３の設置場所まで出向くことなく、該地上子３から離れた基地局１から送信された電文情報により行うことができ、電文書換え作業が容易になる。 Further, in the above embodiment, the case where the telegraphic information is transmitted from the base station 1 to the ground unit 3 by radio is described, but the present invention is not limited to this, and the base station 1 and the ground unit 3 are wired. The message information may be transmitted via the wire. In this case, too, the telegram 3 can be rewritten using the telegram information transmitted from the base station 1 away from the ground unit 3 without going to the place where the ground unit 3 is installed. It becomes easy.
　そして、以上の説明においては、保安設備が地上子３である場合について述べたが、本発明はこれに限られず、保安設備は、基地局１から送信される情報を受信する受信手段を備えた、例えば踏切警報機であってもよい。この場合、踏切警報機に書き込まれる情報としては、例えば踏切警報機の鳴動開始時間や、自動踏切遮断機降下開始時間等である。 In the above description, the case where the security facility is the ground unit 3 has been described.
