Abstract:
1. A management system for a game arcade comprising: a plurality of money identification units detecting authenticity of at least money and obtaining a money information; a slave processing unit connected to each of the plurality of money identification units and receiving the money information, each said slave processing unit providing an accounting signal of a predetermined time width from said money identification unit as output; a slave wireless communication unit connected to each slave processing unit; a plurality of master wireless communication units communicating with the slave wireless communication units and receiving the money information; a plurality of master processing units receiving the money information from the plurality of master wireless communication units; and a host computer having at least a storage section for money information received from the plurality of master processing units, wherein said plurality of master wireless communication units and each said slave wireless communication unit have a first to an N-th communication channels with different frequencies, said host computer providing a first communication request signal having a predetermined time width as output to one of said plurality of master processing units at a predetermined period in accordance with a clock signal of an embedded host clock, said host computer providing a second communication request signal as output to another of said plurality of master processing units after a predetermined time from said first communication request signal, one of said plurality of master processing units executing a step for selecting a first one of said communication channels, said one of said plurality of master processing units executing a step for checking an existence or nonexistence of a radio wave of said first one of said communication channels, said one of said plurality of master processing units executing a step for changing from said first one of said communication channels to another one of said communication channels when said radio wave of said first one of said communication channels is detected, said one of said plurality of master processing units executing a step for checking the nonexistence of a radio wave sequentially from said first one of said communication channels and said one of said plurality of master processing units providing a fixing signal as output for fixing a first free communication channel, at least one said slave processing unit executing a step for sequentially switching said communication channels of at least one said slave wireless communication unit and for fixing at least one of said communication channels of said at least one said slave wireless communication unit to said fixing signal when said fixing signal is detected, at least one said slave processing unit executing a step for providing a plurality of accounting signal confirmation signals as output during a first predetermined time within the time width of the accounting signal, said at least one said slave processing unit executing a step for storing a counted value of said accounting signal when said accounting signal exists at said one of said accounting confirmation signals provided as output, said at least one said slave processing unit executing a step for transmitting said stored counted value and a check information to at least one of said master wireless communication units, said at least one of said master wireless communication units storing said count value when said at least one of said master wireless communication units determines said check information is true.
