[Second Embodiment]
Next, a station placement design system using a station placement design robot according to a second embodiment of the present invention will be described. In the placement design system using the placement design robot according to the present embodiment, the placement design simulation apparatus uses the placement design simulation apparatus based on the radio wave intensity and the handover state at each position in the floor collected by the placement design robot.

With reference to FIG. 2A thru | or FIG. 4, the structure and operation | movement of an installation design system using the installation design robot are demonstrated.

(Overview)
2A and 2B are diagrams for explaining the outline of a station placement design system using the station placement design robot 210 according to the present embodiment.

  FIG. 2A shows an outline of measurement of radio field intensity from a base station by a station design robot.

  The left diagram of FIG. 2A shows a state in which the wireless access points 221 and 222 are arranged in the floor 200 by performing station placement design. In the left diagram of FIG. 2A, it is assumed that the radio wave environment is good. In the right diagram of FIG. 2A, since two tall cabinets are placed in the floor 200, the radio wave condition is expected to deteriorate at the location of ★.

  In this embodiment, the station placement design robot 210 moves within the floor 200 and measures the received signal strength from the wireless access points 221 and 222 at each position, so that a change in radio wave condition can be detected. The measured radio field strength information in the floor 200 from the station design robot 210 is taken into account together with the measured handover information between the wireless access points 221 and 222, and the station design simulation apparatus takes into account the environmental changes in the floor 200. The corresponding station design change is simulated and notified to the user. Note that it is not necessary that the radio field intensity is strong, and the radio field intensity that is weak enough to maintain the quality without interference with the wireless access points 221 and 222 leads to power saving.

When the station-design robot 210 moves to the right position in FIG. 2B while maintaining the call state, a handover from the wireless access point 221 to 222 is performed, and a high-quality call is maintained. The placement station design robot 210 detects the handover state during movement and notifies the placement station design simulation apparatus. Note that the handover state includes maintaining the quality of the call state during handover, the number of handovers, and the like. The measured handover status information in the floor 200 from the placement design robot 210 is taken into account together with the measured received radio wave intensity information, and the placement design simulation apparatus is adapted to the placement design corresponding to the environmental change in the floor 200. The change is simulated and notified to the user.

  In step S1011, the station placement design robot 210 determines whether or not it is a self-running movement instruction to the self-running unit. If it is a self-running movement instruction, the station placement design robot 210 acquires and sets the movement target position in step S1013. The station placement design robot 210 executes a self-running control process in step S1015.

  If it is not a self-propelled movement instruction, the station placement design robot 210 determines in step S1021 whether it is a measurement of the radio field intensity of the received signal. If the radio field intensity is to be measured, the station location design robot 210 measures the radio field intensity of the received signal in step S1023. In step S1025, the station placement design robot 210 stores the radio wave intensity measured in association with the current position information.

  If it is not a self-propelled movement instruction and the radio field intensity is not measured, the station location design robot 210 determines in step S1031 whether it is the start of measurement of the handover state. If the measurement of the handover state is started, the station placement design robot 210 performs communication connection (call connection) processing in step S1033. In step S1035, the station placement design robot 210 acquires information on the access points connected in the communication connection (call connection) process. In step S1037, the station placement design robot 210 instructs a movement target position of the station placement design robot 210 for measuring the handover state.

  If it is not a self-propelled movement instruction, radio wave intensity measurement, and no handover state measurement start, the station location design robot 210 determines in step S1041 whether or not the handover state measurement is complete. If the measurement of the handover state is completed, the station placement design robot 210 acquires a history of handover during a call in step S1043. In step S1045, the station placement design robot 210 stores the acquired handover history during a call in association with the position information. The station location design robot 210 disconnects the call in step S1047.

  If it is not a self-propelled movement instruction, it is not a measurement of the radio field intensity, and neither the measurement of the handover state starts nor the end of measurement, the station placement design robot 210 determines whether or not it is an output of the measurement result in step S1051. . If it is the output of the measurement result, the placement design robot 210 outputs the distribution of signal radio wave intensity and the handover state to the placement design simulation apparatus 330 in association with the position information in the floor in step S1053.

A data output step of outputting the measured radio wave intensity distribution in the floor and the handover state in association with position information in the floor;
Including
The station design simulation apparatus is
A reception step of receiving, from the station design robot, the measured radio field intensity distribution and handover state in the floor in association with position information in the floor;
A simulation step of simulating a station location design in the floor based on the measured distribution of radio field strength in the floor and the state of the handover;
A simulation result output step for outputting a simulation result of the station placement design;
Stationary design method including
