In this channel switching control system, a plurality of channel terminals ch1 to ch8 and two channel terminals among these channel terminals ch1 to ch8 are connected, and a signal input from each channel terminal is branched in two directions and output. , One of the two branch outputs of the hybrid circuits 71a to 71d and the hybrid circuits 71a to 71d, each of which is a square transmission line having a quarter wavelength, is output by delaying one output by a predetermined phase shift. 72a to 72d, the hybrid circuits 73a to 73d for branching the signals output from these phase shifters and the like, and one of the two branch outputs of each of the hybrid circuits 73a to 73d is delayed by a predetermined phase shift. And phase shifters 74a to 74d to be output, and hybrid circuits 75a to 75d for branching the signals output from these phase shifters and the like into two The transmission elements # 1 to # 8 of the multi-beam antenna 76 are configured, and the transmission elements # 1 to # 8 are selectively driven so as to have different excitation phases while giving a time difference from the hybrid circuits 75a to 75d. For example, as illustrated in FIG. 13, the transmission signal is electrically transmitted at a scanning angle of 1R to 4R by scanning in eight directions every ８.
[0056]
FIG. 14 is a diagram showing an example in which a sensor to which, for example, five multi-beam antennas 76-1 to 76-5 are installed is turned in the horizontal direction. For example, when detecting an object up to a distance of 60 m, in order to detect at an interval of 20 m, the multi-beam antenna is installed at 0 degree, ± 41 degrees, and ± 61 degrees with respect to an axis perpendicular to the guide path. . The detection of ± 23 degrees between 0 degrees and ± 41 degrees and ± 52 degrees between ± 41 degrees and ± 61 degrees is, for example, in the case of 23 degrees, with multi-beam antennas 76-2 and 76-3. Can be interpolated by outputting from the output, and as a result, it is possible to monitor the range of −60 degrees to +60 degrees in the horizontal direction in 11 scans.
[0057]
Therefore, as described above, the aircraft detection sensor 34 is scanned up and down and swiveled in the horizontal direction, whereby the reception level at each scanning angle can be acquired in time series as shown in FIG. When the reception level is connected, it can be detected as a vehicle, and when the reception level is at the lower right side, it can be detected as an aircraft.
[0058]
Therefore, according to the above embodiment, while collecting and managing the information related to the operation plan from the outside, the operation plan is obtained from the information related to the operation plan collected by the operation management device 41 of the evaluation display system 4. Or predicting the optimal route when the intersection is overcrowded, and performing collision avoidance processing according to the approaching state of the moving object, and displaying it on the display unit 424 of the evaluation display device 42 when there is an abnormality. It is possible to quickly grasp the congestion situation at the intersection.
[0059]
The evaluation display device 42 of the evaluation display system 4 is selected from the information management device 1, the lighting control system 2, the non-cooperating sensor system 3, etc. when the operation buttons required by the controller are selectively operated. The system automatically captures information, executes the process corresponding to the operation button, and displays the execution result on the monitoring screen, so the controller can display the necessary status while cooperating with the devices and systems that make up the system. Can easily monitor necessary information.
[0060]
Further, since the information management apparatus 1 in the system collects necessary information from outside the system regardless of the inside of the system, the information can be efficiently collected without affecting the system of the present invention.
[0061]
Furthermore, the lighting control controller 28 and the non-cooperative sensor controller 36 are connected by the dedicated network 29, and the presence / absence detection information of the moving body captured by the non-cooperating sensor controller 36 is transmitted from the dedicated network 29 to the lighting control controller 28. The lamp control controller 28 can quickly control the lamp 24 based on the presence / absence detection information of the moving object.
[0062]
Further, the non-cooperative sensor system 3 is installed at an airport intersection and a taxiway connected to each intersection, and a mobile body detection sensor 34 that detects the presence or absence of the mobile body, and wirelessly and closed circuit from these mobile body detection sensors By providing a non-cooperative sensor controller 36 that receives the moving body presence / absence detection information via the network and transmits the guiding guidance information to the guiding guidance light 32 connected to the moving body detecting sensor, the operation management apparatus 41 Since an appropriate route is selected in advance based on the congestion state of the airport and displayed on the guidance guide light 32, safe guidance control of a moving body traveling in the airport can be supported.
[0063]
Furthermore, the moving body detection sensor 34 performs vertical scanning and horizontal turning scanning using a multi-beam antenna from a direction orthogonal to the passing direction of the moving body. Therefore, it is possible to recognize a moving body in three dimensions, and thus easily recognize the passage of a vehicle other than an aircraft.
[0064]
Further, as the evaluation display system 4, a simulator system 44 is connected to the evaluation display device 42 via the information system LAN, and a fixed airport model image is displayed in advance, and the evaluation display device is displayed on the model image. Since the moving body output from 42 is displayed in three dimensions and can be monitored from four directions, multiple controllers can monitor the same information at the same time, and errors in control operations can be obtained. .
[0065]
Furthermore, the simulator system 44 is provided with abnormality indicator lights 76a to 76d, and when the abnormality is determined by the collision avoidance process of the moving body by the operation management device 41, the abnormality is displayed, so that the abnormal state is accurately recognized. It becomes possible to do.
[0066]
Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, each device 1, 41, 42, etc. is provided with a program memory for storing a program in addition to the database, but each program may also be stored in the database.
[0067]
