列車速度監控系統train speed monitoring system

本發明是有關於一種監控系統，尤其是一種列車速度監控系統。The present invention relates to a monitoring system, especially a train speed monitoring system.

列車自動保護系統(Automatic Train Protection，ATP)，是一種列車輔助駕駛系統，可於列車超過規定速度時自動制軔的系統，而該列車自動保護系統會設置地面裝置，以接收軌道旁邊的燈號裝置的燈號資訊。Automatic Train Protection (ATP) is a train assisted driving system that can automatically stop the train when it exceeds a specified speed, and the automatic train protection system will be equipped with ground devices to receive the lights next to the track. The light information of the device.

目前設置於軌道旁的燈號裝置設置有綠燈及紅燈，紅燈狀態禁止列車往前通行，綠燈狀態時列車才可以往前通行，列車的駕駛必須依據燈號操控列車，而列車自動保護系統則為列車操控系統的監控系統，可以輔助駕駛操控列車，避免燈號裝置亮紅燈時列車還繼續往前行駛。At present, the light signal device installed next to the track is equipped with green light and red light. The red light state prohibits the train from passing forward. The train can only pass forward when the green light is on. The driver of the train must control the train according to the light signal, and the train automatic protection system It is the monitoring system of the train control system, which can assist the driver to control the train and prevent the train from continuing to move forward when the red light is on.

參閱圖1，為中華民國專利號I579163，說明一種列車控制系統的車上裝置1，該列車控制系統的車上裝置天線11，用以接收列車控制資訊的ATC訊號；車上無線機12，用以接收列車控制資訊的CBTC訊號；ATC控制部13，可基於該ATC訊號所包含之列車控制資訊來控制列車；CBTC控制部14，可基於該CBTC訊號所包含之列車控制資訊來控制列車；以及選擇部15，用以選擇ATC控制部13或CBTC控制部14；速度檢測器16可偵測車速。Referring to FIG. 1, it is the Republic of China Patent No. I579163, which describes an on-board device 1 of a train control system. The on-board antenna 11 of the train control system is used to receive the ATC signal of the train control information; the on-boardwireless device 12 is used for to receive the CBTC signal of the train control information; the ATCcontrol part 13 can control the train based on the train control information contained in the ATC signal; theCBTC control part 14 can control the train based on the train control information contained in the CBTC signal; and Theselection part 15 is used to select the ATCcontrol part 13 or theCBTC control part 14; thespeed detector 16 can detect the vehicle speed.

該ATC控制部13可基於位置資訊及速度資訊來掌握列車的位置及速度，該ATC訊號所包含之停止區間資訊(及限制速度資訊)，基於所生成之速度對照模式來進行列車的煞車控制，以控制列車的速度。The ATCcontrol unit 13 can grasp the position and speed of the train based on the position information and speed information, and the stop section information (and speed limit information) contained in the ATC signal is used to control the braking of the train based on the generated speed comparison pattern, to control the speed of the train.

雖然習知技術揭露了一種軌道列車之車速控制技術，但是實際使用時仍具有下列缺點：Although the prior art discloses a speed control technology for rail trains, it still has the following disadvantages in actual use:

一、無線傳輸資訊量受限：由於地面裝置之無線訊號的範圍會有限制，列車的車上裝置進入地面裝置之無線訊號的範圍時，地面裝置與車上裝置才可以傳輸資料，隨著列車速的提升，會造成車上裝置在地面裝置之無線訊號的範圍時間變短，時間將會限制無線資訊的傳輸量，無法傳輸大量的資料。1. The amount of wireless transmission information is limited: Since the range of the wireless signal of the ground device will be limited, when the on-board device of the train enters the range of the wireless signal of the ground device, the ground device and the on-board device can transmit data. The increase of the speed will shorten the range of the wireless signal of the on-board device on the ground, which will limit the amount of wireless information transmission and cannot transmit a large amount of data.

二、沒有監控的記錄：一般列車的操控裝置會設置行車資訊記錄設備(俗稱黑盒子)，主要的目的是記錄列車的操控，但是目前並未針對列車自動保護系統的監控記錄進行儲存，檢修人員無法判斷列車自動保護系統是否發生故障。2. Records without monitoring: Generally, the control device of the train will be equipped with a driving information recording device (commonly known as a black box), the main purpose is to record the control of the train, but the monitoring records of the automatic train protection system are not currently stored. Maintenance personnel It is impossible to judge whether the automatic train protection system is faulty.

三、無法提供預警：目前是以道旁裝置的位置來取得軌道位置，在針對所在位置的速限資料對列車的操控系統進行監控，一般列車駕駛並無法得知後續軌道位置的速限資料。3. Unable to provide early warning: Currently, the position of the trackside device is used to obtain the track position, and the control system of the train is monitored according to the speed limit data of the location. Generally, the train driver cannot know the speed limit data of the subsequent track position.

因此，如何在提升車速的條件下保有較佳的資訊傳輸量，並針對列車的監控歷史進行記錄，更可以預先告知駕駛接近軌道位置的速件資料，是相關技術人員亟需努力的目標。Therefore, how to maintain a better amount of information transmission under the condition of increasing the speed of the vehicle, record the monitoring history of the train, and also inform the driver of the speed information of the position close to the track in advance, is an urgent goal for relevant technicians.

該資料輸出裝置33設置於該軌道21中並與該資料輸出模組324電連接，該資料接收裝置34設置於該列車23上並與該資料輸出裝置33資訊連接，較佳地，該資料輸出裝置33與該資料接收裝置34為對應的RFID讀寫器，實際實施時，該資料輸出裝置33與該資料接收裝置34可以使用其他無線的資訊收發器，不應以此為限，由於RFID讀寫器為習知技術，並廣泛運用於市售產品中，於此不再詳加贅述。Thedata output device 33 is disposed in thetrack 21 and is electrically connected to thedata output module 324. Thedata receiving device 34 is disposed on thetrain 23 and is informationally connected to thedata output device 33.

In actual implementation, thedata output device 33 and thedata receiving device 34 can use other wireless information transceivers, which should not be limited to this. The writer is a conventional technology and is widely used in commercially available products, so it will not be described in detail here.

Themonitoring device 35 can be other programmable control equipment, thedata input module 351, themonitoring module 352, thedatabase module 353, the direction storage module 355, and the record storage module 356 are related chip circuits , should not be limited by this.

於該較佳實施例，該資料輸入模組351控制該資料接收裝置34對外發出無線之一觸發資料，該資料輸出模組324藉由該資料輸出裝置33收到該觸發資料時至該資料暫存模組323讀取該傳輸資料並以無線發出，以使該資料輸入模組351藉由該資料接收裝置34接收該傳輸資料，該資料庫模組353中儲存複數對應不同之位置資料的速限資料，該監控模組352將該傳輸資料解碼以取得該位置資料及該道旁資料並至該資料庫模組353檢索出對應該位置資料之速限資料，該監控模組352依據該道旁資料及該速限資料監控該操控裝置24。In this preferred embodiment, thedata input module 351 controls thedata receiving device 34 to send out a trigger data wirelessly to the outside, and thedata output module 324 receives the trigger data through thedata output device 33 until the data is temporarily Thestorage module 323 reads the transmission data and sends it wirelessly, so that thedata input module 351 receives the transmission data through thedata receiving device 34, and thedatabase module 353 stores a plurality of speeds corresponding to different location data. Limit data, themonitoring module 352 decodes the transmission data to obtain the position data and the roadside data, and then retrieves the speed limit data corresponding to the position data to thedatabase module 353, and themonitoring module 352 uses the track data to retrieve the speed limit data. Thecontrol device 24 is monitored by the side data and the speed limit data.

該監控模組352與該車速偵測模組241電連接以取得該列車23之一車速資料，該監控模組352依據該道旁資料及該速限資料分析該車速資料，該監控模組352依據分析的結果監控該操控裝置24。該監控模組352與該車速控制模組242電連接，當該車速資料大於該速限資料時，該監控模組352控制該車速控制模組242，以使該列車23之速度小於該速限資料。Themonitoring module 352 is electrically connected to the vehiclespeed detection module 241 to obtain vehicle speed data of thetrain 23. Themonitoring module 352 analyzes the vehicle speed data according to the roadside data and the speed limit data. Themonitoring module 352 Thecontrol device 24 is monitored as a function of the results of the analysis. Themonitoring module 352 is electrically connected to the vehiclespeed control module 242. When the vehicle speed data is greater than the speed limit data, themonitoring module 352 controls the vehiclespeed control module 242 so that the speed of thetrain 23 is lower than the speed limit material.

除此之外，由於該道旁資料為該列車23在該軌道21的開放通行資料或禁止通行資料，當該道旁資料為禁止通行的道旁資料時，該監控模組352可以主動控制該車速控制模組242，或是通知駕駛控制該車速控制模組242，以將該列車23煞停。In addition, since the roadside data is the open traffic data or the prohibited traffic data of thetrain 23 on thetrack 21, when the roadside data is the prohibited traffic data, the supervisor willThecontrol module 352 can actively control thespeed control module 242 or notify the driver to control thespeed control module 242 to stop thetrain 23 .

舉例來說，該列車23經過該資料輸出裝置33時，該資料接收裝置34與該資料輸出裝置33交換資料，以使該監控模組352取得具有該道旁資料及該位置資料的傳輸資料，該監控模組352對該傳輸資料進行解析，以取得該道旁資料及該位置資料，當該道旁資料為該軌道21可通行列車23的資訊時(例如燈號裝置亮綠燈時)，該監控模組352允許駕駛操控列車23於該軌道21上前行，當該道旁資料為該軌道21禁止列車23通行的資訊時(例如燈號裝置亮紅燈時)，該監控模組352分析該車速偵測模組241以判定該列車23的速度是否正在下降或煞停，或是分析該車速控制模組242駕駛是否啟動該列車23的煞車，以使該列車23在該道旁裝置22的前方停止前進。For example, when thetrain 23 passes thedata output device 33, thedata receiving device 34 exchanges data with thedata output device 33, so that themonitoring module 352 obtains the transmission data with the roadside data and the position data, Themonitoring module 352 analyzes the transmission data to obtain the roadside data and the position data. When the roadside data is the information of thetrain 23 that can pass on the track 21 (for example, when the light signal device is on green), theThe monitoring module 352 allows the driver to control thetrain 23 to travel on thetrack 21. When the roadside data is the information that thetrain 23 is prohibited from passing on the track 21 (for example, when the light signal device lights up red), themonitoring module 352 analyzes The vehiclespeed detection module 241 determines whether the speed of thetrain 23 is decreasing or braking, or analyzes whether the vehiclespeed control module 242 activates the braking of thetrain 23, so that thetrain 23 is on theroadside device 22 stop ahead.

除此之外，該監控模組352會以該位置資料至該資料庫模組353中檢索對應的速限資料，接著該監控模組352會以檢索到的速限資料分析該車速偵測模組241的車速資料，當該車速資料大於該速限資料，該監控模組352會由該顯示模組354輸出告警資料，以提醒駕駛將該列車23的速度降低，或是主動控制該車速控制模組242，自動將該列車23的速度降低，以使該列車23的車速資料低於該速限資料，讓該列車23可以安全地行駛於該軌道21上。In addition, themonitoring module 352 will use the location data to retrieve the corresponding speed limit data from thedatabase module 353, and then themonitoring module 352 will analyze the vehicle speed detection module based on the retrieved speed limit data. The speed data ofgroup 241, when the speed data is greater than the speed limit data, themonitoring module 352 will output alarm data from the display module 354 to remind the driver to reduce the speed of thetrain 23, or actively control the speed control Themodule 242 automatically reduces the speed of thetrain 23 so that the speed data of thetrain 23 is lower than the speed limit data, so that thetrain 23 can travel on thetrack 21 safely.

一般來說，RFID無線資訊傳輸的範圍約在10公尺以下，該資料輸出裝置33與該資料接收裝置34之無線傳輸的範圍有限，當列車23以高速於軌道21上行駛時，該資料輸出裝置33與該資料接收裝置34的無線資料傳輸時間非常的短，該資料暫存模組323可供該道旁控制模組321先將資料準備好，當該列車23接近，該資料接收裝置34以該觸發資料要求該資料輸出裝置33將該道旁資料及該位置資料輸出時，該資料輸出模組324直接至該資料暫存模組323讀取資料，將該道旁裝置22的即時道旁資料傳輸給該監控模組352，該道旁控制模組321不需要受該資料輸出模組324的請重新取得該狀態偵測模組311的資料，有效縮短無線訊號輸出的時間，讓該列車23通過該資料輸出裝置33時，可以更快速的取得具有道旁資料及位置資料的傳輸資料，或是在有限的傳輸時間中傳輸更多的資料量。Generally speaking, the range of RFID wireless information transmission is about 10 meters or less, and the wireless transmission range of thedata output device 33 and thedata receiving device 34 is limited. When thetrain 23 runs on thetrack 21 at high speed, the data output The wireless data transmission time between thedevice 33 and thedata receiving device 34 is very short. The datatemporary storage module 323 can be used by theroadside control module 321 to prepare the data first. When thetrain 23 approaches, thedata receiving device 34 with the trigger dataWhen thedata output device 33 is required to output the roadside data and the position data, thedata output module 324 directly reads the data from the datatemporary storage module 323, and transmits the real-time roadside data of theroadside device 22 to Themonitoring module 352 and theroadside control module 321 do not need to be subject to thedata output module 324, please re-obtain the data of thestate detection module 311, which effectively shortens the time of wireless signal output and allows thetrain 23 to pass the When thedata output device 33 is used, the transmission data with the roadside data and the position data can be obtained more quickly, or a larger amount of data can be transmitted in a limited transmission time.

該列車監控裝置35更包括一與該監控模組352電連接之聲音警報模組357，該監控模組352判斷該列車23的車速資料已大於該速限資料，控制該聲音警報模組357發出聲音警報，由於該列車23的駕駛在操控該列車23時，需要注意該列車23前方的軌道21狀況，可於緊急事件時將該列車23進行煞停，因此駕駛很難專注視覺的警告資料，因此該聲音警報模組357可以於該列車23需要減速或煞停時，以語音提醒駕駛，讓駕駛在專注列車23前方狀況時可以收到該監控裝置輸出的警報資料，並適時的將該列車23煞停。Thetrain monitoring device 35 further includes an audio alarm module 357 electrically connected to themonitoring module 352. Themonitoring module 352 determines that the speed data of thetrain 23 is greater than the speed limit data, and controls the audio alarm module 357 to issue Sound alarm, since the driver of thetrain 23 needs to pay attention to the condition of thetrack 21 in front of thetrain 23 when manipulating thetrain 23, thetrain 23 can be braked in an emergency, so it is difficult for the driver to focus on the visual warning information, Therefore, the sound alarm module 357 can remind the driver by voice when thetrain 23 needs to decelerate or stop, so that the driver can receive the alarm data output by the monitoring device when the driver is focusing on the situation ahead of thetrain 23, and timely call thetrain 23 stop.

該監控模組352可以控制該顯示模組354輸出該道旁資料及該速限資料，以使駕駛可以瞭解該列車23的位置資料，以及對應該位置資料的速限資料，其中，該顯示模組354可以整合於該操控裝置24的顯示介面，不應以此為限。Themonitoring module 352 can control the display module 354 to output the roadside data and the speed limit data, so that the driver can know the position data of thetrain 23 and the speed limit data corresponding to the position data, wherein the display module The group 354 can be integrated into the display interface of thecontrol device 24, and should not be limited thereto.

該列車監控裝置35更包括一與該監控模組352電連接之方向儲存模組355，該操控裝置24可控制該列車23於該軌道21以一行駛方向前進，該監控模組352將該行駛方向儲存在該方向儲存模組355。該資料庫模組353中更儲存複數對應該複數速限資料的排序資料，該排序資料是依據該道旁裝置22設置於該軌道21之位置進行排序，該監控模組352依據接收之位置資料及該行駛方向至該資料庫模組353進行檢索，以取得該列車23下一經過之道旁裝置22之位置資料及對應的速限資料，由於該軌道21的通行方向為順行或逆行，因此該資料庫模組353可以儲存該位置資料及對應的速限資料，並加上排序特徵，讓該監控模組352可以藉由該位置資料的排序關係進行資料的檢索。Thetrain monitoring device 35 further includes a direction storage module 355 electrically connected to themonitoring module 352. Thecontrol device 24 can control thetrain 23 to move forward on thetrack 21 in a traveling direction, and themonitoring module 352 will drive thetrain 23. The direction is stored in the direction storage module 355 . Thedatabase module 353 further stores a plurality of sorting data corresponding to the plurality of speed limit data. The sorting data is sorted according to the position of theroadside device 22 on thetrack 21 , and themonitoring module 352 is based onThe received position data and the travel direction are retrieved to thedatabase module 353 to obtain the position data and the corresponding speed limit data of theroadside device 22 that thetrain 23 will pass next. Therefore, thedatabase module 353 can store the position data and the corresponding speed limit data, and add a sorting feature, so that themonitoring module 352 can perform data retrieval according to the sorting relationship of the position data.

舉例來說，該列車23經過之資料輸出裝置33的位置資料為120K+300，該列車23的行駛方向為順行方向，該監控裝置於該資料庫模組353檢索對應該位置資料的速限資料為120公里/小時，同時該監控裝置會取得該列車23下一個會經過的資料輸出裝置33的位置資料為120K+900及對應的速限資料為110公里/小時，或是可以再檢索下下一個會經過的資料輸出裝置33的位置資料(121K+200)及對應的速限資料(100公里/小時)，並將檢索資料輸出於該顯示裝置上，以提供駕駛提前將該列車23的速度控制於該速限資料內，或是下一位置的資料輸出裝置33發生故障而接收不到該位置資料，駕駛及該列車監控裝置35就可以藉由檢索的資料控制該列車23的速度。For example, the position data of thedata output device 33 passing by thetrain 23 is 120K+300, the traveling direction of thetrain 23 is the forward direction, and the monitoring device searches thedatabase module 353 for the speed limit corresponding to the position data The data is 120 km/h, and at the same time, the monitoring device will obtain the position data of thedata output device 33 that thetrain 23 will pass next, which is 120K+900 and the corresponding speed limit data is 110 km/h, or it can be retrieved again. The position data (121K+200) and the corresponding speed limit data (100 km/h) of thedata output device 33 that will pass next, and the retrieval data is output on the display device to provide the driver with the information about thetrain 23 in advance. If the speed is controlled within the speed limit data, or thedata output device 33 at the next position fails and cannot receive the position data, the driver and thetrain monitoring device 35 can control the speed of thetrain 23 based on the retrieved data.

該監控模組352將對該操控裝置24的監控資料儲存在該記錄儲存模組356中，舉例來說，該監控模組352可以將該列車23經過的該位置資料、對應該位置資料的速限資料、該顯示模組354與該聲音警報模組357的輸出資料、該車速偵測模組241的車速資料，以及該監控模組352對該車速控制模組242的控制資料(包括加速、減速，及煞停等資料)，檢修人員可藉由該記錄儲存模組356中儲存的資料判斷該列車監控裝置35是否故障，較佳地，該列車速度監控系統更包含一可與該列車監控裝置35資訊連接之自動檢修裝置36，該自動檢修裝置36中儲存一分析資料，檢修人員可以將該自動檢修裝置36與該列車監控裝置35電連接，或是以無線傳輸的方式進行資訊連接，以使該自動檢修裝置36可以與該監控模組352傳輸資料並取得該記錄儲存模組356中儲存的資料，該自動檢修裝置36依據該分析資料來分析該記錄儲存模組356中儲存的資料，以判斷該列車監控裝置35是否正常，或是進一步分析是否有遺漏的資料未進行記錄，舉例來說，該列車23經過該位置資料(200K+300)時應該與該位置資料的資料輸出裝置33傳輸資料，以取得該資料控制裝置32輸出的位置資料及道旁資料，但是該記錄儲存模組356中並未儲存該位置資料(200K+300)的相關監控資料，表示該資料控制裝置32可能發生零件故障，檢修人員可以前往該位置資料對該道旁監控裝置31、該資料控制裝置32、該資料輸出裝置33，及該電源供應裝置42進行檢修，除此之外，該自動檢修裝置36更可以藉由分析該記錄儲存模組356中儲存的資料，來判斷該列車監控裝置35或該操控裝置24是否發生故障，該分析資料為該記錄儲存模組356中正確的儲存資料，因此當該記錄儲存模組356中儲存的資料與該分析資料不符合時，就可以判斷該列車監控裝置35或該操控裝置24發生故障，檢修人員可先將該列車23上的裝置更換成備品，以使該列車23上的操控裝置24及該列車監控裝置35為可以正常工作的裝置，來確保該列車23於軌道21上通行的安全，之後檢修人員再對卸下的裝置進行檢查及維修。Themonitoring module 352 stores the monitoring data of thecontrol device 24 in the recording storage module 356. For example, themonitoring module 352 can store the position data of thetrain 23 passing by, the speed corresponding to the position data. limit data, the output data of the display module 354 and the sound alarm module 357, the speed data of thespeed detection module 241, and the control data of themonitoring module 352 to the speed control module 242 (including acceleration, Data such as deceleration, braking, etc.), the maintenance personnel can judge whether thetrain monitoring device 35 is faulty based on the data stored in the record storage module 356. Preferably, the train speed monitoring system further includes a Theautomatic maintenance device 36 to which thedevice 35 is information-connected, an analysis data is stored in theautomatic maintenance device 36, and the maintenance personnel can electrically connect theautomatic maintenance device 36 with thetrain monitoring device 35, or use theThe information is connected by means of line transmission, so that theautomatic maintenance device 36 can transmit data with themonitoring module 352 and obtain the data stored in the record storage module 356, and theautomatic maintenance device 36 analyzes the record according to the analysis data. The data stored in the storage module 356 is used to determine whether thetrain monitoring device 35 is normal, or to further analyze whether there are missing data that have not been recorded. For example, when thetrain 23 passes the location data (200K+300), it should be It transmits data with thedata output device 33 of the position data to obtain the position data and roadside data output by thedata control device 32, but the record storage module 356 does not store the relevant monitoring of the position data (200K+300). The data indicates that thedata control device 32 may have a component failure, and the maintenance personnel can go to the location data to perform maintenance on theroadside monitoring device 31, thedata control device 32, thedata output device 33, and thepower supply device 42, except for In addition, theautomatic maintenance device 36 can judge whether thetrain monitoring device 35 or thecontrol device 24 is faulty by analyzing the data stored in the record storage module 356, and the analysis data is the record storage module Therefore, when the data stored in the record storage module 356 does not match the analysis data, it can be determined that thetrain monitoring device 35 or thecontrol device 24 is faulty, and the maintenance personnel can first The devices on 23 are replaced with spare parts, so that thecontrol device 24 on thetrain 23 and thetrain monitoring device 35 can be normal working devices to ensure the safety of thetrain 23 on thetrack 21. After that, the maintenance personnel will unload them again. Check and repair the device below.

由上述說明可知，本發明一種列車速度監控系統確實具有下列功效：As can be seen from the above description, a train speed monitoring system of the present invention does have the following effects:

The time for information transmission can be shortened: the datatemporary storage module 323 stores the trackside data in advance. When thedata output device 33 receives the trigger data sent by thedata receiving device 34, thedata output module 324 Read the data stored in the datatemporary storage module 323 and send it to the outside world, no longer time-consumingWait for theroadside control module 321 to calculate the data to be transmitted, and transmit the roadside data to thetrain monitoring device 35 in a limited time.

三、可發佈後續速限：該資料庫模組353中儲存的速限資料是依據該位置資料進行排序，因此該監控模組352檢索到一速限資料時，可以再取得該列車23在後續位置資料時的速限資料，當該道旁監控裝置31、該資料控制裝置32，或該資料輸出裝置33發生故障，而使該列車監控裝置35未收到該位置資料及該道旁資料時，該監控模組352還是可以依據取得的後續速限資料對該操控裝置24進行監控。3. Subsequent speed limit can be published: the speed limit data stored in thedatabase module 353 is sorted according to the location data, so when themonitoring module 352 retrieves a speed limit data, it can obtain thetrain 23 for subsequent speed limit data Speed limit data at the time of location data, when thewayside monitoring device 31, thedata control device 32, or thedata output device 33 fails, so that thetrain monitoring device 35 does not receive the location data and the wayside data , themonitoring module 352 can still monitor thecontrol device 24 according to the obtained subsequent speed limit data.

綜上所述，該資料暫存模組323可以預先儲存該位置資料相關的道旁資料，可提供該資料輸出模組324需要傳輸資料時，直接讀取該資料暫存模組323中的資料並進行傳送，有效縮短無限資料傳輸的時間，該記錄儲存模組356可以儲存該操控裝置24的監控資料，並提供該自動檢修裝置36進行資料的分析，以判斷該列車監控裝置35、該道旁監控裝置31、該資料控制裝置32、該資料輸出裝置33，及該資料接收裝置34是否發生故障，該監控模組352檢索對應該位置資料的速限資料時，可以將該列車23接下來會遇到的位置資料所對應的速限資料調出，當該列車23經過該軌道21位置但該列車監控裝置35未收到列車監控裝置35時，該監控模組352就可以依據檢索的資料對該操控裝置24進行監控，故確實可以達成本發明之目的。To sum up, the datatemporary storage module 323 can pre-store the roadside data related to the location data, which can provide thedata output module 324 to directly read the data in the datatemporary storage module 323 when it needs to transmit data and transmission, effectively shortening the time of unlimited data transmission, the record storage module 356 can store the monitoring data of thecontrol device 24, and provide theautomatic maintenance device 36 to analyze the data to determine thetrain monitoring device 35, the track Whether theside monitoring device 31, thedata control device 32, thedata output device 33, and thedata receiving device 34 are faulty, when themonitoring module 352 retrieves the speed limit data corresponding to the location data, thetrain 23 can be next The speed limit data corresponding to the position data that will be encountered is called up. When thetrain 23 passes the position of thetrack 21 but thetrain monitoring device 35 does not receive thetrain monitoring device 35, themonitoring module 352 can retrieve the data according to the retrieved data. Thecontrol device 24 is monitored, so the object of the present invention can be achieved indeed.

惟以上所述者，僅為本發明之一個較佳實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above is only a preferred embodiment of the present invention, and should not limit the scope of implementation of the present invention, that is, simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the description of the invention. , all still fall within the scope covered by the patent of the present invention.
