Abstract

An automatic lubricating oil feeding system is disclosed which can centralistically control a plurality of dependent terminals to feed lubricating oil to required machine elements, such as bearings, at proper times by receiving the operation state information from the respective terminals. The system includes a host controller which utilizes a personal computer programmed to supervise, check, and display terminal state information, and an RF section, coupled to the personal computer via an interface, for transmitting command data of the personal computer and receiving the terminal state information data through a radio communication network. The system further includes at least one terminal comprising a lubricating oil discharge control device having a mechanical unit for discharging lubricating oil, a microprocessor for controlling the operation of the mechanical unit, and an RF section, coupled to the lubricating oil discharge control device, for receiving from the host controller the command data for controlling the lubricating oil discharge control device and transmitting to the host controller the terminal state information data resulting from a self-test of the lubricating oil discharge control device through the radio communication network.
