摘要：
A wireless communication device in a data collection system starts measuring a time when the wireless communication device receives a wireless signal from a data collection device. The wireless communication device changes the wireless channel, transmits a detection signal for detecting the data collection device, and starts measuring a time after transmitting the detection signal when the wireless communication device is unable to receive a next wireless signal from the data collection device even after passage of a predetermined time since the wireless communication device has previously received the wireless signal. The wireless communication device changes the wireless channel to be used, depending on whether the wireless communication device has received a response signal from the data collection device in response to the detection signal within a predetermined time.
