Excerpt
Excerpt
It is an object of the invention to provide work control system that can prevent an interference of the transmitting signals of the power tools in relation to the work progress. A representative work control system according to the present teachings may include a plurality of power tools and detecting device. Each of the power tools may transmit signals relating to the work progress. The detecting device may detect the work progress of each of the power tools by receiving and detecting the signals transmitted from the respective power tools. The signals relating to the work progress may be transmitted from each power tool several times. Preferably, the transmission intervals may vary among the power tools in order to prevent the signals from being confused. A work control system according to the present teachings may include a plurality of power tools and detecting device. Each of the power tools may transmit signals relating to the work progress. The detecting device may detect the work progress of each of the power tools by receiving and detecting the signals transmitted from the respective power tools. The signals relating to the work progress may be transmitted from each power tool several times. Preferably, the transmission intervals may vary among the power tools in order to prevent the signals from being confused. According to one aspect of the present teachings, a representative work control system to utilize power tools may be constructed. The system may include a plurality of power tools and a detecting device. The detecting device may receive signals in relation to work progress of the power tools. The signals may be transmitted from the respective power tools so that the detecting device may detect the work progress of each power tool. Each power tool may transmit signals several times and transmission intervals of the signals vary among the power tools. In other words, the time intervals in transmitting signals are different in relation to the respective power tools. As a result, even if the detecting device receives signals relating to the work progress from power tools at the same time, the signals are subsequently transmitted from each power tool at the intervals that vary among the power tools. In other words, even if the detecting device receives the first signals from the plurality of power tools at the same time and even if any interference may be caused among the signals due to such receipt of the signals at the same time, the second signals can be transmitted from each power tool at different timing because the transmission intervals of the signals vary among the power tools. Thus, it is made possible to positively identify and control the work progress of each of the power tools without causing interference due to simultaneous reception of the signals.
