That is, the interlocking device 5 periodically transmits the route configuration state and the track circuit state, and performs period monitoring for monitoring the presence or absence of a route configuration request from the mobile terminal 9.

  Next, the operation of the vehicle base replacement work support system according to the first embodiment will be described with reference to FIGS.

  FIG. 3 is a flowchart for explaining processing of the ground management device 3 at the time of input of the premises work plan of the vehicle base replacement work support system according to the first embodiment. When the plan is created, the plan manager operates the plan input unit 2 of the ground management device 3 to cause the ground management device 3 to start start time, start number, end time, and replacement notice in the vehicle base. Replacement work information consisting of information such as time, replacement delay monitoring time, end number, signal type, driver, merger presence / absence, division presence / absence, inspection work and cleaning work start time, end time, work notice time The in-house work plan including the inspection / cleaning work information composed of information such as work number and work team is registered (step ST101). Here, the replacement notice time means the time for displaying the start notice of the replacement work on the driver's portable terminal 9 before the start time of the vehicle replacement work, and the work notice time is the inspection time. -Before the start time of cleaning work, it indicates the time for displaying the start notice of the inspection / cleaning work on the portable terminal 9 for workers. The replacement delay monitoring time refers to a time for displaying the replacement delay warning for the replacement work on the ground management device 3 before the start time of the vehicle replacement work. The on-site work plan is automatically assigned a plan number (step ST102), and is transferred to the portable terminal 9 together with the plan number by the plan manager operating the plan input unit 2 (step ST103). Thereafter, it is determined whether there is a change in the premises work plan (step ST104).

  When there is a change in the premises work plan (step ST104: Yes), the yard work plan is changed by the plan manager operating the plan input unit 2 of the ground management device 3 (step ST105). Return to processing. If there is no change in the premises work plan (step ST104: No), the process of step ST104 is repeated. When the on-site work plan is changed, the plan number is automatically updated (step ST102), and the plan manager operates the plan input unit 2 so that the on-site work plan is transferred to the portable terminal 9 together with the plan number. (Step ST103). Thereafter, the ground management device 3 repeatedly performs the processing of step ST102 to step ST105.

  FIG. 4 is a flowchart for explaining processing of the mobile terminal 9 for the driver of the in-vehicle base replacement work support system according to the first embodiment. In the portable terminal 9 for the driver, after storing the plan number and the premises work plan transferred from the ground management device 3 (step ST103: see FIG. 3) (step ST201), the driver in charge of the replacement work inputs The driver name is registered by operating the unit 7 (step ST202). Thereafter, the track circuit state, the course configuration state, the plan progress state, and the plan number are received from the ground management device 3 (step ST203), and the ground management device 3 indicates that its own terminal is being replaced. If the terminal status is set to “in progress” or “standby” indicating that the replacement work has been completed or has been completed, and the route configuration request is set in the own terminal, the route configuration request is also included.

  Next, the plan number received in step ST203 is compared with the plan number transferred from the ground management apparatus 3 in step ST103 (see FIG. 3) and stored in step ST201 (step ST205). If the plan numbers match (step ST205: Yes), the process proceeds to step ST207. If the plan numbers do not match (step ST205: No), it is determined that the on-site work plan has been changed, and a display to the effect that the on-site work plan has been changed is displayed on the display unit 6 (step ST206). The process proceeds to step ST207.

  Subsequently, it is determined whether or not the terminal state of the own terminal is “switching” (step ST207). When the terminal state of the terminal itself is “switching” (step ST207: Yes), it is determined whether information from the ground management device 3 is received within a certain time (step ST208), and within a certain time If no information is received (step ST208: No), the route abnormality is displayed on the display unit 6 (step ST209), and the process returns to step ST204. When information is received within a certain time (step ST208: Yes), it is determined whether or not the self-replacement route configuration is normal based on the route configuration state received from the ground management device 3 (step ST210). If the self-replacement route configuration is not normal (step ST210: No), the route abnormality is displayed on the display unit 6 (step ST209), and the process returns to step ST204. When the self-replacement route configuration is normal (step ST210: Yes), it is determined whether or not the replacement work has been completed (step ST211). If the replacement work has been completed (step ST211: Yes), the display unit 6 displays the completion of replacement (step ST212), and sets “standby” as the terminal state of the terminal itself (step ST213). The process returns to step ST204. When the replacement work has not been completed (step ST211: No), the normal course is displayed on the display unit 6 (step ST214), and the process returns to step ST204.

  When the terminal state of the terminal is not “replacement” (step ST207: No), that is, when it is “standby”, from the current time to the start time of replacement work that is next responsible by the terminal. It is determined whether or not the time is less than a preset replacement notice time (step ST215).

During the replacement work, the ground management device 3 periodically communicates with both the interlocking device 5 and the mobile terminal 9 to determine whether or not there is a route configuration request in the information received from the mobile terminal 9 ( Step ST301). When there is no route configuration request (step ST301: No), the process proceeds to step ST304. When there is a route configuration request (step ST301: Yes), a route configuration request is made to the interlocking device 5 (step ST302), and the planned progress state of the replacement work based on the route configuration request is set to “replacement start”. (Step ST303), the process proceeds to step ST304.

  Subsequently, the presence / absence of information from the interlocking device 5 is determined (step ST304). If there is no information from the interlocking device 5 (step ST304: No), the process returns to step ST301, and the information from the interlocking device 5 is changed. If there is (step ST304: Yes), the track circuit state and the course configuration state are received from the interlocking device 5 (step ST305).

  Subsequently, it is determined whether or not the terminal state of the portable terminal 9 that has transmitted the route configuration request is “standby”, that is, whether or not the replacement work based on the route configuration request has been completed (step ST306). When the terminal state is not “standby”, that is, when it is “switching” (step ST306: No), the process proceeds to step ST308. When the terminal state is “standby” (step ST306: Yes), it is determined that the replacement work has ended, and the planned progress state of the replacement work is set to “replacement end” (step ST307). The process proceeds to step ST308. Then, the track circuit state and the route configuration state received from the interlocking device 3 and the plan progress state and the plan number managed by the ground management device 3 are sent to all the mobile terminals 9 from the ground side radio device 4 and the terminal side radio. Broadcast distribution is performed via the device 8 (step ST308).

  Further, it is determined whether or not the time from the current time to the start time of the replacement work that has not been started is less than a preset replacement delay monitoring time (step ST309), and the switching delay monitoring time or more If (step ST309: No), the process returns to step ST301. If it is less than the replacement delay monitoring time (step ST309: Yes), it is determined that the replacement work may be delayed or has already been delayed, and a replacement delay warning is displayed on the display unit 1. (Step ST310), and the process returns to step ST301. Thereafter, the ground management device 3 periodically repeats the processes in steps ST301 to ST310.
