Field of the Invention The present invention relates to a train control communication device, and more particularly to a train control communication device capable of effectively preventing interference. 2. Description of the Related Art Conventionally, for example, a train control communication device used for an ATS-P type train control system has a transmission / reception provided with an on-vehicle (on-vehicle antenna) at the lower part of the head of the train. It is composed of an on-board device consisting of an airplane and a ground device provided with a ground child (ground antenna) on the ground along a track (rail). [0003] In the above configuration, when the train travels on the track and the upper child reaches the radio communication area of the ground child, distance information from the ground device is received by the on-vehicle device via the ground child and the vehicle child. At the same time, the on-board device generates a traveling pattern taking into account the braking (brake) characteristics of the own train,
Control the train so that it can reach the stop target point in the shortest time. The above-mentioned terrestrial device receives a power wave from an on-vehicle child by a terrestrial child and converts the received input into electric power, in addition to a powered type in which the ground device itself has a power source for driving the terrestrial device. There is a non-powered type that drives a ground device to transmit data stored in the ground device to the upper side of the vehicle. Therefore, when the non-powered type is included as the ground equipment, the train always outputs not only the data transmission but also the power wave whose output is larger than that of the data transmission from the vehicle upper side to the ground side. Running on orbit. [0005] In recent years, along with the sophistication of train control, in addition to the above-mentioned data transmission and reception using a vehicle upper child and a ground child, other types of data are used. A plurality of transmission devices are used in combination, and the amount of data transmission tends to increase. In such a plurality of types of data transmission, every possible measure is taken to make the frequencies different from each other so as not to interfere with each other, but there is a limit to the frequencies that can be used. There is a possibility that the radio waves may interfere and degrade the communication quality. [0006] In particular, as described above, when traveling on a track while transmitting strong radio waves from a vehicle, there is a possibility that the influence on other transmission devices laid along the track may be increased. Therefore, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a section in which data transmission is not required from the vehicle upper side to the ground side. The purpose of the present invention is to provide a train control communication device capable of canceling transmission of data and eliminating the influence on other transmission devices. [0008] In order to achieve the above object, a train control communication device according to the present invention is provided with a vehicle arm provided on a train running on a track along the track. A train control communication device that transmits data from the upper side of the vehicle to the ground side or from the ground side to the upper side of the vehicle via the upper child and the lower child when approaching the ground child. On the upper side of the vehicle, when data from a predetermined ground child among the ground children is received, data from the vehicle upper side to the ground side is received.
Stopping means for stopping data transmission, and resuming means for resuming data transmission from the vehicle upper side to the ground side when data from a predetermined ground child other than the predetermined ground child is received. It is characterized by having. In the above construction, the stopping means stops data transmission from the vehicle upper side to the ground side when receiving data from a predetermined ground child among the ground children on the vehicle upper side. Therefore, the train stops data transmission to the ground side and runs. The resuming means, when receiving data from other ground children except the ground child, receives data from the vehicle upper side to the ground side.
Start data transmission. Therefore, hereafter, the train travels while transmitting predetermined data to the ground side. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a schematic diagram of a train control communication device according to one embodiment of the present invention, and FIG. 1B is a time chart thereof. The train a is equipped with a well-known on-board device 3 consisting of a transmitter / receiver 2 having an upper arm 1 at the lower part of the head.
The vehicle is traveling on a track (rail) R in the direction of the arrow. The ground equipment 4 includes a code processor (not shown),
A plurality (five in the illustrated example, for simplicity of the drawing) of power-supply type ground terminals 5a to 5e connected to the code processor, and further, a plurality of (two in the illustrated example) And non-power-supply type ground terminals (ground devices) 6a and 6b. Each of the powered ground members 5a to 5c is disposed at a predetermined interval along the track R, and the non-powered ground members 6a and 6b are connected to the powered ground members 5a and 5b. And 5d and 5e, respectively. The ground members 5c and 5d are respectively provided at the start point and the end point of a section which does not interfere with the running of the train a even if no data is transmitted from the train a to the ground side. Then, off data for stopping the transmission of the onboard device 3 is transmitted from the ground child 5c, and the transmission of the onboard device 3 is restarted from the ground child 5d. ON data is transmitted. In the above configuration, the on-board device 3
The vehicle travels on the track R while transmitting predetermined data to the ground side via the vehicle arm 1, and predetermined data is transmitted toward the vehicle from each of the ground members 5a to 5c and 6a. (See ground children 5a to 5c in FIG. 1B). Therefore,
When the vehicle upper child 1 and the ground children 5a to 5c and 6a approach each other, data is exchanged between the upper side of the vehicle and the ground side to be used for controlling the train. When the train a reaches the ground child 5c, OFF data is input from the ground child 5c to the on-vehicle device 3, so that the on-vehicle device 3 travels to the ground via the vehicle child 1 until then. Data transmission that has been transmitted (including power waves for driving the non-power-supply type ground terminals 6a and 6c. Therefore, in the present invention, data transmission to the ground side includes power waves. Is stopped, and the vehicle continues to run as it is (see the grounding elements 5c to 5d in FIG. 1B). Therefore, in this section, no radio wave is transmitted from the train a toward the ground side, so that there is no adverse effect on other transmission devices (not shown) installed in this section. When the train a continues to travel and the train a reaches the ground child 5d, ON data is input from the ground child 5d to the on-board device, so that the on-board device 3 is again directed to the ground side. To resume predetermined data transmission (see FIG. 1 (b)).
d to 5e). As described above, the train control communication device according to the present embodiment can actively stop data transmission in sections where data transmission is not necessary from the upper side of the vehicle to the ground side. Therefore, there is no adverse effect on other transmission devices in that section. Therefore, in that section,
By selecting and arranging a transmission device that is easily affected by the upper side of the vehicle, communication quality can be improved. The train control communication device according to the present invention is designed such that when a vehicle upper arm provided on a train running on a track approaches a ground arm provided along the track, the vehicle is controlled. In a train control communication device for transmitting data from the upper side of the vehicle to the ground side or from the ground side to the upper side of the vehicle via the upper child and the ground child, Means for stopping transmission of data from the upper side of the vehicle to the ground side when data from the predetermined ground element is received, and data from a predetermined ground element other than the predetermined ground element. -When receiving the data,
Since there is a resuming means for resuming data transmission from the vehicle upper side to the ground side, the section which does not need data transmission from the vehicle upper side to the ground side actively transmits the data transmission. Since the transmission can be stopped, there is no adverse effect on other transmission devices in that section. Therefore, in that section, a transmission device that is easily affected by the upper side of the vehicle can be selected and arranged to improve the quality of communication.
