When a request signal and a danger signal are transmitted to the second control unit 23 , the second control unit 23 generates a request signal for requesting access to the alarm unit 20 that is generated from the injection unit 10 and is set in advance, and an alarm It can be determined whether the permission signal that is generated from the unit 20 and that permits only the access of the injection unit 10 set in advance is matched.

The second control unit 23 determines whether the injection unit 10 can be connected to the alarm unit 20 set in advance based on the information about the injection unit 10 and the alarm unit 20 stored in the request signal and the permission signal. can judge

Only the preset alarm unit 20 can detect and deliver abnormal symptoms of the driving state of the driving unit 113 of the preset injection unit 10 by judging whether the request signal and the permission signal match, so alarm accuracy There is an effect that can be improved.
