4. It comprises a command identification device 115, an I / F control unit 116, a dedicated I / F control unit 105 having a memory controller 117, and a signal line 106.

The operation of monitoring the temperature and voltage according to the present embodiment will be described with reference to FIGS. The timing generator 103 acquires data from the temperature sensor 101 and the voltage monitoring sensor 102, and generates a timing for storing the acquired data in the memory 104. This timing can be changed by changing the set value of the timing interval register 113 in response to a request from the main device 200. At the timing output from the timing generator 103, the temperature / voltage sensor control unit 114 acquires data from the temperature sensor 101 and the voltage monitoring sensor 102, and acquires the acquired data through the memory controller 117 at the acquisition time and temperature data. Are stored in the log data storage table 201 (see FIG. 2) in the nonvolatile memory 104 together with the voltage data.

The command identification device 115 identifies the command sent from the main unit 200, and if the command is a data acquisition request command from the temperature sensor 101, notifies the temperature / voltage sensor control unit 114 of the command and transmits the acquired data to the I / O controller 114. / F control unit 11
At 6, the main unit 200 is notified through the signal line 106.

If the command from the main unit 200 is a command to request data acquisition from the voltage monitoring sensor 102, the temperature / voltage sensor is similarly notified and the acquired data is sent to the I / O sensor.
The F control unit 116 notifies the main unit 200 via the signal line 106.

Further, if the command from the main unit 200 is a log data acquisition command, the number of logs to be read is further acquired via the signal line 106, the memory controller 117 is notified, and the log data is read from the nonvolatile memory 104. Is notified to the main unit 200 via the signal line 106 by the I / F control unit 116 for the requested number.

If the command from the main unit 200 is a request for changing the timing time, it notifies the timing interval register 113 to change the set value.

At the time of startup, the current time is requested from the main unit 200, and the current time is stored in the startup time register 111 through the signal line 106.

The alarm detecting device 112 monitors the data acquired by the temperature / voltage sensor control unit 114 from the temperature sensor 101 and the voltage monitoring sensor 102, and when the environmental condition is exceeded, the I / F control unit 116 Then, an error is notified to the main unit 200 through the signal line 106.
