[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0021] like Figure 1 The figure shows a crane's enclosed electrical room positioning smoke alarm device. A metallurgical casting machine includes two electrical rooms. Five smoke detectors 1 are installed in the first electrical room, each 3 meters apart and numbered 1-5. Five smoke detectors 1 are also installed in the second electrical room, numbered 6-10. A signal converter 2 is installed in each of the first and second electrical rooms. The signal converters 2 are connected to several smoke detectors 1 (wirelessly in this embodiment), which in turn are connected to an alarm host 3 (wirelessly in this embodiment).

[0022] When smoke is detected in the electrical room, the signal converter 2 amplifies the power of the alarm signal sent by the smoke detector 1 and transmits it to the alarm host 3. The alarm host 3 sounds an alarm to remind the operator in the cab, and the specific number of the alarming smoke detector 1 is displayed on the interface of the alarm host 1, so as to quickly determine the location of the fire. The operator notifies the staff to deal with it as soon as possible to avoid the expansion of the fire accident.

[0023] The alarm host 3 at least includes a display screen, a processing module, a power-off module and an alarm.
