Description

列車速度臨時制限装置Train speed temporary limiter
　本発明は、列車速度を臨時に制限する列車速度臨時制限装置に関する。 The present invention relates to a temporary train speed limiter that temporarily limits the train speed.
　従来、列車制御技術としては、ＡＴＣ（Automatic Train Control）装置や、ＣＢＴＣ（Communications-Based Train Control）システムなどが知られている。その他に、これらのシステムに対してコスト優位性を持つ点式ＡＴＳ－Ｐ（Automatic Train Stop system-Pattern）システム（以下、点式ＡＴＰシステムと略称する）も周知である。 Conventionally, as a train control technology, an ATC (Automatic Train Control) device, a CBTC (Communications-Based Train Control) system, and the like are known. In addition, a point ATS-P (Automatic Train Stop System-Pattern) system (hereinafter abbreviated as a point ATP system) having a cost advantage over these systems is also well known.
　点式ＡＴＰシステムは、例えば、特許文献１に開示されているように、列車の走行する線路に沿い、相互に所定の間隔を置いて、地上子を設置し、これらの地上子により速度制限情報を送信する。これを車上装置で受信することにより、列車の制限速度に基づく速度パターンを生成する。そして、この速度パターンで指定される速度を超えないように、列車の速度を制御する。 For example, as disclosed in Patent Document 1, the point-type ATP system installs ground elements at predetermined intervals along a track on which a train travels, and speed limit information is provided by these ground elements. Send. By receiving this by the on-board device, a speed pattern based on the speed limit of the train is generated. Then, the speed of the train is controlled so as not to exceed the speed specified by this speed pattern.
　ところで、気象条件が急減に悪化、あるいは線路の改修等の設備工事等のために、列車速度を臨時に制限しなければならないことがある。ＡＴＣ装置や、ＣＢＴＣシステムを採用している場合には、軌道回路や無線により、車上装置に列車速度臨時制限情報を伝送することができる。 By the way, the weather speed may suddenly decrease or the train speed may need to be temporarily limited due to equipment construction such as track repair. When the ATC device or the CBTC system is adopted, the train speed temporary restriction information can be transmitted to the on-board device by a track circuit or wirelessly.
　ところが、点式ＡＴＰシステムを用いている場合には、次に述べるような事情から、車上装置に列車速度臨時制限情報を伝送することが困難である。 However, when the point ATP system is used, it is difficult to transmit the temporary train speed limit information to the on-board device due to the following circumstances.
（ａ）線路改修等の設備工事等の行われる工事区間が予め分かっている場合には、例えば、朝令等において、列車速度を臨時に制限すべき区間を運転士に知らせておくことによって、対処することができる。 (A) When the construction section where equipment construction such as track repair is carried out is known in advance, for example, by informing the driver of the section where the train speed should be limited temporarily, Can be dealt with.
　しかし、線路改修等の設備工事等であっても、突発的緊急性が要求されることがある。また、強風や豪雨などの気象条件は、予期し得ない状態で発生し、激変することも多い。このような突発的緊急事態の場合には、朝令等において、列車速度を臨時に制限すべき区間を運転士に知らせておくことによって、対処することができない。 However, sudden urgency may be required even for equipment construction such as track repair. Also, weather conditions such as strong winds and heavy rains occur unexpectedly and often change drastically. Such a sudden emergency situation cannot be dealt with by notifying the driver of the section where the train speed should be temporarily limited at a morning age or the like.
（ｂ）工事区間に進入する前の位置に、臨時速度制限用地上子を設けておく等の対策をとることも考えられる。しかし、予期し得ない気象条件の変化、突発的な線路改修等の設備工事等には、対処することができない。 (B) It may be possible to take measures such as providing a temporary speed limiting ground element at a position before entering the construction section. However, it cannot cope with unforeseen changes in weather conditions, equipment construction such as sudden rail repairs, etc.
（ｃ）従来の点式ＡＴＰシステムでは、地上子から送信された電文データの受信順番を、車上装置が確認する仕組みになっている。このため、工事区間に進入する前の位置に、臨時速度制限用地上子を設けておく等の対策をとることができない。 (C) In the conventional point type ATP system, the on-board device confirms the order of reception of the telegram data transmitted from the ground unit. For this reason, it is not possible to take measures such as providing a temporary speed limiting ground element at a position before entering the construction section.

　本発明の課題は、点式ＡＴＰシステムの利点であるコスト優位性を活かしたままで、気象条件の急減な悪化や、線路の改修等の設備工事等のための列車速度臨時制限を確実に、かつ、安全に実行し得る列車速度臨時制限装置を提供することである。 The object of the present invention is to make use of the cost advantage that is the advantage of the point-type ATP system, to ensure the sudden deterioration of weather conditions, and to temporarily limit the train speed for equipment construction such as track repair, and It is to provide a train speed temporary limiter that can be executed safely.
　上述した課題を解決するため、本発明に係る列車速度臨時制限装置は、列車制御区間のある区域において列車速度を臨時に制限すべきことを指示する臨時速度制限情報を伝送する情報伝送路と、前記情報伝送路から供給された前記臨時速度制限情報を送信する地上装置と、臨時速度制限情報を受信したとき、列車速度臨時制限速度に基づく臨時速度パターンを生成し、この臨時速度パターンを他の速度パターンより優先させて、列車の速度を制御する車上装置と、を備える。 In order to solve the above-described problem, the train speed temporary restriction device according to the present invention is an information transmission path for transmitting temporary speed restriction information instructing that the train speed should be temporarily restricted in a certain area of the train control section, When receiving the temporary speed limit information and the ground device that transmits the temporary speed limit information supplied from the information transmission path, a temporary speed pattern based on the train speed temporary limit speed is generated, and the temporary speed pattern An on-board device that controls the speed of the train in preference to the speed pattern.
　上述したように、本発明に係る列車速度臨時制限装置は、情報伝送路を含んでいる。この情報伝送路は、列車制御区間のある区域において列車速度を臨時に制限すべきことを指示する臨時速度制限情報を伝送する。よって、臨時速度制限情報を、列車速度を臨時に制限すべき区域を含む列車制御区間の位置まで、伝送することができる。臨時速度制限情報には、気象条件の急減な悪化や、線路の改修等の設備工事等に応じた適切な臨時速度の情報が含まれている。 As described above, the train speed temporary restriction device according to the present invention includes an information transmission path. This information transmission path transmits temporary speed limit information instructing that the train speed should be temporarily limited in an area having a train control section. Therefore, the temporary speed limit information can be transmitted to the position of the train control section including the area where the train speed should be temporarily limited. The temporary speed limit information includes information on temporary speeds appropriate for the sudden deterioration of weather conditions and equipment construction such as railway repairs.
　前記地上装置は、前記情報伝送路から供給された臨時速度制限情報を送信する。車上装置は、臨時速度制限情報を受信して、列車速度臨時制限速度に基づく臨時速度パターンを生成する。この臨時速度パターンを他の速度パターンより優先させて、列車の速度を制御する。これにより、点式ＡＴＰシステムが構成される。 The ground device transmits the temporary speed limit information supplied from the information transmission path. The on-board device receives the temporary speed limit information and generates a temporary speed pattern based on the train speed temporary limit speed. This temporary speed pattern is prioritized over other speed patterns to control the train speed. Thereby, a point type ATP system is constituted.
　従って、点式ＡＴＰシステムの利点であるコスト優位性を活かしたままで、気象条件の急減な悪化や、線路の改修等の設備工事等のための列車速度臨時制限を確実に、かつ、安全に実行し得る列車速度臨時制限装置及び列車制御装置を提供することができる。
　前記情報伝送路は、運行管理情報を伝送する既設のＬＡＮ（Local Area Network）によって構成することができる。これにより、情報伝送線路を新たに敷設する必要がなくなるから、この面でも、コストダウンに寄与することができる。 Therefore, while taking advantage of the cost advantage that is the advantage of the point-type ATP system, the temporary speed limitation of the train speed for facility construction such as sudden deterioration of weather conditions and repair of the track is executed reliably and safely. A train speed temporary restriction device and a train control device that can be provided can be provided.
The information transmission path can be configured by an existing LAN (Local Area Network) that transmits operation management information. This eliminates the need for newly laying an information transmission line, and this aspect can also contribute to cost reduction.
　前記地上装置は、具体的には、符号処理部と、地上子とを含む構成とすることができる。この場合、前記符号処理部は、前記情報伝送路から供給された前記臨時速度制限情報を解読して電文を生成し、前記地上子は、前記電文を送信する。 Specifically, the ground device can include a code processing unit and a ground unit. In this case, the code processing unit decodes the temporary speed limit information supplied from the information transmission path to generate a telegram, and the ground unit transmits the telegram.
　以上述べたように、本発明によれば、点式ＡＴＰシステムの利点であるコスト優位性を活かしたままで、気象条件の急減な悪化や、線路の改修等の設備工事等のための列車速度臨時制限を確実に、かつ、安全に実行し得る列車速度臨時制限装置を提供することができる。 As described above, according to the present invention, while taking advantage of the cost advantage, which is an advantage of the point-type ATP system, the train speed is temporarily reduced due to sudden deterioration of the weather conditions or equipment construction such as repair of the track. It is possible to provide a temporary train speed limiting device that can reliably and safely execute a limit.
本発明に係る列車制御装置の構成を示す図である。It is a figure which shows the structure of the train control apparatus which concerns on this invention.
　図を参照すると、本発明に係る列車速度臨時制限装置は、情報伝送路１と、地上装置３１～３３と、車上装置７とを含む。情報伝送路１は、線路５に沿い、複数の列車制御区間Ｄ１～Ｄ４に跨って、連続して敷設され、列車制御区間Ｄ１～Ｄ４の、或る区域ΔＰにおいて列車速度を臨時に制限すべきことを指示する臨時速度制限情報を伝送する。区域ΔＰは、図１（Ａ）の場合、列車制御区間Ｄ１に隣接する列車制御区間Ｄ２にあり、列車制御区間Ｄ１－Ｄ２の境界を基準地点Ｐ０とした地点Ｐ１，Ｐ２の間に位置する。 Referring to the figure, the train speed temporary restriction device according to the present invention includes an information transmission path 1, ground devices 31 to 33, and an on-board device 7. The information transmission path 1 should be continuously laid along a line 5 across a plurality of train control sections D1 to D4, and the train speed should be temporarily limited in a certain section ΔP of the train control sections D1 to D4. Temporary speed limit information is transmitted. In the case of FIG. 1A, the zone ΔP is in the train control section D2 adjacent to the train control section D1, and is located between the points P1 and P2 with the boundary of the train control section D1-D2 as the reference point P0.
　情報伝送路１は、運行管理情報を伝送する既設のＬＡＮによって構成することができる。運行管理情報を伝送する既設のＬＡＮは、本来的には、運行管理装置１１から供給される運行管理情報を伝送するものである。本発明では、このＬＡＮを、臨時速度制限情報伝送手段として兼用する。よって、臨時速度制限情報は、運行管理装置１１から情報伝送路１に供給されることになる。 The information transmission path 1 can be configured by an existing LAN that transmits operation management information. The existing LAN that transmits the operation management information originally transmits the operation management information supplied from the operation management device 11. In the present invention, this LAN is also used as a temporary speed limit information transmission means. Therefore, the temporary speed limit information is supplied from the operation management device 11 to the information transmission path 1.
　地上装置３１～３３は、列車制御区間Ｄ１～Ｄ４毎に備えられ、情報伝送路１から供給された臨時速度制限情報を、車上装置７の受信し得る信号として送信する。実施例では、列車制御区間Ｄ１～Ｄ４は、駅間の区間、例えば、駅Ａ１と駅Ａ２との間の列車制御区間Ｄ２、駅Ａ２と駅Ａ３との間の列車制御区間Ｄ３として表現されている。各列車制御区間Ｄ１～Ｄ４の境界に信号機９１～９３が配置されている。もっとも、列車制御区間Ｄ１～Ｄ４は、駅間の中間的な区間であってもよい。列車７０が、駅Ａ１の存在する列車制御区間Ｄ１に位置する図１の場合、臨時速度制限情報は地上装置３１から送信され、それが車上装置７によって受信され、必要な列車制御が実行される。 The ground devices 31 to 33 are provided for each of the train control sections D1 to D4, and transmit the temporary speed limit information supplied from the information transmission path 1 as a signal that can be received by the on-board device 7. In the embodiment, the train control sections D1 to D4 are expressed as sections between stations, for example, a train control section D2 between the stations A1 and A2, and a train control section D3 between the stations A2 and A3. Yes. Traffic lights 91 to 93 are arranged at the boundaries of the train control sections D1 to D4. However, the train control sections D1 to D4 may be intermediate sections between stations. In the case of FIG. 1 where the train 70 is located in the train control section D1 where the station A1 exists, the temporary speed limit information is transmitted from the ground device 31, which is received by the onboard device 7, and necessary train control is executed. The
　地上装置３１～３３は、具体的には、符号処理部３１１，３２１，３３１と、地上子３１２，３２２，３３２とを含む構成とすることができる。この場合、符号処理部３１１，３２１，３３１は、情報伝送路１から供給された臨時速度制限情報を解読して電文を生成する。地上子３１２，３２２，３３２は、その電文を送信する。 Specifically, the ground devices 31 to 33 can include code processing units 311, 321, and 331 and ground units 312, 322, and 332. In this case, the code processing units 311, 321, 331 decode the temporary speed limit information supplied from the information transmission path 1 and generate a message. The ground units 312, 322, and 332 transmit the electronic message.
　車上装置７は、前記線路５に沿って走行する列車７０に搭載され、地上子３１２，３２２，３３２から送信された信号を受信する。より具体的には、ＡＴＳ－Ｐ型の車上装置７を構成する。この種の車上装置７の場合は、情報伝送路１及び地上装置３１～３３を経由して、臨時速度制限情報を受信したとき、列車速度臨時制限速度に基づく臨時速度パターンを生成する。この臨時速度パターンを他の速度パターンより優先させて、列車７０の速度を制御する点式ＡＴＰシステムを構成する。車上装置７は、地上子３１２，３２２，３３２と電磁結合等によって結合する車上子７２と、ＡＴＳ－Ｐの処理をする信号処理部７１とを有し、列車７０に搭載されている。 The on-board device 7 is mounted on a train 70 that travels along the track 5 and receives signals transmitted from the ground elements 312, 322, and 332. More specifically, the ATS-P type on-board device 7 is configured. In the case of this type of on-board device 7, when temporary speed limit information is received via the information transmission path 1 and the ground devices 31 to 33, a temporary speed pattern based on the train speed temporary limit speed is generated. The temporary ATP system that controls the speed of the train 70 is configured by giving priority to this temporary speed pattern over other speed patterns. The on-board device 7 includes an on-board element 72 that is coupled to the ground elements 312, 322, and 332 by electromagnetic coupling and the like, and a signal processing unit 71 that performs ATS-P processing, and is mounted on the train 70.
　上述したように、本発明に係る列車速度臨時制限装置は、情報伝送路１を含んでおり、情報伝送路１は、線路５に沿い複数の列車制御区間Ｄ１～Ｄ４にわたって敷設されている。この情報伝送路１は、列車制御区間Ｄ１～Ｄ４のある区域ΔＰにおいて列車速度を臨時に制限すべきことを指示する臨時速度制限情報を伝送する。従って、臨時速度制限情報を、列車速度を臨時に制限すべき区域ΔＰを含む列車制御区間Ｄ１～Ｄ４の位置まで、伝送することができる。臨時速度制限情報には、気象条件の急減な悪化や、線路５の改修等の設備工事等に応じた適切な臨時速度の情報が含まれている。 As described above, the train speed temporary restriction device according to the present invention includes the information transmission path 1, and the information transmission path 1 is laid along the track 5 over a plurality of train control sections D 1 to D 4. This information transmission path 1 transmits temporary speed limit information instructing that the train speed should be temporarily limited in an area ΔP having the train control sections D1 to D4. Accordingly, the temporary speed limit information can be transmitted to the positions of the train control sections D1 to D4 including the section ΔP where the train speed should be temporarily limited. The temporary speed limit information includes information on appropriate temporary speeds according to a sudden deterioration in weather conditions, facility construction such as repair of the track 5, and the like.
　本発明に係る列車速度臨時制限装置は、地上装置３１～３３を含んでいる。地上装置３１～３３は、線路５に設定された区間毎に備えられ、情報伝送路１から供給された臨時速度制限情報を、車上装置７によって受信可能な信号として送信する。 The train speed temporary restriction device according to the present invention includes ground devices 31-33. The ground devices 31 to 33 are provided for each section set on the track 5 and transmit the temporary speed limit information supplied from the information transmission path 1 as a signal that can be received by the on-board device 7.
　そして、車上装置７により、臨時速度制限情報を受信して、図１（Ｂ）に示すように、列車速度臨時制限速度に基づく速度パターンＳＰ１を生成する。列車７０の走行速度Ｖ１がこの速度パターンＳＰ１で指定される速度Ｖ１を超えないように、走行パターンＳＰ２に従って列車速度を制御する。このようにして、点式ＡＴＰシステムを構成することができる。 Then, the on-board device 7 receives the temporary speed limit information and generates a speed pattern SP1 based on the train speed temporary limit speed as shown in FIG. The train speed is controlled according to the travel pattern SP2 so that the travel speed V1 of the train 70 does not exceed the speed V1 specified by the speed pattern SP1. In this way, a point ATP system can be configured.
　従って、コスト優位性を活かしたままで、気象条件の急減な悪化や、線路５の改修等の設備工事等に対応して要求される列車速度臨時制限を確実に、かつ、安全に実行し得る列車速度臨時制限装置及び列車制御装置を提供することができる。 Therefore, a train that can reliably and safely execute the temporary speed limit required in response to sudden deterioration of weather conditions and equipment construction such as repair of the railway line 5 while taking advantage of cost advantage. A temporary speed limit device and a train control device can be provided.
　情報伝送路１は、運行管理情報を伝送する既設のＬＡＮによって構成することができる。これにより、情報伝送線路５を新たに敷設する必要がなくなるから、この面でも、コストダウンに寄与することができる。 The information transmission path 1 can be configured by an existing LAN that transmits operation management information. Thereby, since it is not necessary to newly lay the information transmission line 5, it can contribute to cost reduction also in this aspect.
