More specifically, the communication state acquisition unit 152 of the main control unit 150 acquires one of the communication states A to D of the communication unit 120. Here, for example, it is assumed that the current communication state is the communication state B.

  Next, the main control unit 150 acquires the communication elapsed time (H) corresponding to the communication state acquired in S1 from the first information table 131 in the storage unit 150 (S2). Here, for example, the main control unit 150 acquires the communication elapsed time tb (H) corresponding to the communication state B from the first information table 131.

Selects a communication state associated with a communication speed close to the current communication speed from among the communication states A to D stored in the first information table 131 (S6). Then, the communication state control unit 155 changes the current communication state to the communication state selected in S6 and operates the communication unit 120 (S7). For example, when the communication speed acquisition unit 151 acquires the wireless 5G communication speed 200 (Mbps), the communication state control unit 155 selects the current communication among the communication states A to D stored in the first information table 131. The communication state D associated with the communication speed close to the speed (wireless 5G communication speed 200 (Mbps)) is selected (S7), the communication state B is changed to the communication state D, and the communication unit 120 is operated. Then, the main control unit 150 performs the process of S1 again.

The temperature (case surface temperature) is stored in association with each other. Thereby, the specific location temperature (case surface temperature) when the communication unit 120 is operated in each of the communication states A to D can be known without using a temperature sensor.

  Further, the specific location temperature comparison unit (housing surface temperature comparison unit 154) includes the specific location temperature (housing surface temperature) acquired from the first information table 131 and the specific location temperature (housing surface measured in advance). Compare with the maximum value of (temperature). Thereby, the specific location temperature (case surface temperature) when the communication unit 120 is operated in each of the communication states A to D is measured in advance without using the temperature sensor. It is possible to know whether or not it has become higher than the maximum value of).

  Then, the communication state control unit 155 selects any one of the communication states A to D stored in the first information table 131 based on the comparison result of the specific location temperature comparison unit, and sets the communication unit in the selected communication state. 120 is operated.

If the surface temperature is equal to or higher than the maximum value, the communication state control unit 155 changes the communication speed to the communication state associated with the communication speed close to the communication speed of the communication unit 120 acquired by the communication speed acquisition unit 151, and performs communication. The unit 120 is operated. Thereby, the communication part 120 can select and communicate an appropriate communication state so that specific location temperature (case surface temperature) may become below that maximum value, without using a temperature sensor.

  On the other hand, the specific location temperature (housing surface temperature) acquired from the first information table 131 by the housing surface temperature acquisition unit (housing surface temperature acquisition unit 153) is the specific location temperature (housing surface measured).
