摘要： A temperature management system includes: temperature detection units which individually detect temperatures of a plurality of electronic devices each changing an amount of heat generation depending on its operational state; a cooling device which cools the electronic devices; and a control unit which controls the cooling device depending on outputs from the temperature detection units. The control unit includes: an idle state determination unit which determines whether or not the electronic devices are in an idle state; a manipulated variable calculation unit which has an integrator and calculates a manipulated variable by using a difference between a target value and a controlled variable; and an accumulation value correction unit which corrects an accumulation value of the integrator with a predetermined value when the idle state determination unit determines that the electronic devices are in the idle state.

摘要： A communication control device includes an authentication login information storage unit that stores therein authentication login information. When a terminal device connects to a first communication port among a plurality of communication ports, the communication control device compares login information received from the terminal device with the authentication login information, and if they match, the communication control device outputs a command received from the terminal device. A control device includes an authentication unique information storage unit that stores therein authentication unique information. When the communication control device outputs the command received from the terminal device, the control device compares the unique information of the terminal device with the authentication unique information, and if they match, causes a processor to perform only a process of reading control information according to the command received from the terminal device.
