Compared with the existing technology, the utility model adopts various methods (such as sound and light, SMS) to alarm the temperature and humidity, water leakage, smoke, etc. in the machine room, and the performance is stable and reliable, which can ensure the operation of the door machine room in a stable environment. Improving the information management level of the door machine room can effectively prevent the following situations from happening: (1) The temperature rise caused by the failure of the air conditioner or the damage to the electrical cabinet; (3) The temperature and humidity in the computer room are too high in summer, which leads to frequent equipment failures in the computer room; (4) The electrical cabinet equipment is flooded and malfunctions due to water leakage.

Because mobile phones are communication tools that people use every day, and short messages are an important means of communication for people's daily communication, the utility model uses the ubiquitous GSM network to send alarm short messages to preset administrators, so that relevant personnel can Accept the alarm message and deal with it accordingly.

After the utility model is applied, a large amount of later maintenance and replacement costs can be saved. For example, if the electrical cabinet catches fire, all the lines and electrical parts in the electrical cabinet will be damaged, and the maintenance cost in the later period will be about 10,000 yuan, while the replacement of a new ACC800 inverter will cost 180,000 yuan, and the total maintenance and replacement cost in the later period will be 190,000 yuan About; And the expense of transforming a main engine according to the utility model is 2800 yuan, has saved 187,200. And the application of the utility model also saves the inspection by a special person, and can also cancel a labor expenditure, so the economic benefit brought by installing the system is quite large.

Detailed ways

Embodiment of the present utility model: a multifunctional door machine room alarm system, as shown in FIG. It adopts a special humidity detector for the computer room, the model is RX-185A) and a smoke sensor 4; the host 1 includes a single-chip microcomputer 5 with AD conversion function, an audible and visual alarm 6 (including a buzzer 9 and a light-emitting diode 10), and a short message controller 7 and display screen 11, temperature and humidity sensor 2, water immersion sensor 3, smoke sensor 4, sound and light alarm 6, short message controller 7 and display screen 11 are all connected with single-chip microcomputer 5; Host 1 also includes amplifier circuit 8, temperature and humidity sensor 2. The temperature and humidity, water leakage and smoke signals collected by the water immersion sensor 3 and the smoke sensor 4 are amplified by the amplifier circuit 8 and then enter the single chip microcomputer 5 .

There is a double-sided adhesive tape on the back of the smoke sensor 4, just peel off the plastic film and stick it on the ceiling of the machine room; place the probe piece of the water immersion sensor 3 in the place to be detected for water leakage in the machine room.

The host 1 is provided with binding posts, and the temperature and humidity sensor 2 , the water immersion sensor 3 and the smoke sensor 4 are respectively connected to the binding posts of the host 1 . As shown in Figure 3, the temperature and humidity sensor 2 is connected to terminals 1, 2, 3, and 4 of the host 1 in the order of blue, red, green, and black; On terminal No. 9, the green wire is connected to terminal No. 9; the yellow wire of smoke sensor 4 is connected to terminal No. 8; the yellow wire of water sensor 3 is connected to terminal No. 7.

Working principle: After connecting the wires as shown in Figure 3, plug in the power cord of host 1 and turn on the switch of host 1.

After power on, wait for about 3 minutes (search signal and initialization time); then perform the following settings:

(1) Set the administrator number

Use the mobile phone set as the administrator number to send a text message "set master number x" to the internal card number of the main unit 1, x can be 1, 2, 3, 4, 5, and after the setting is successful, you will receive a successful text message. If you want to change the number, you can directly overwrite it with the new number, or you can send a text message "delete owner number x";

(2) Set the temperature and humidity alarm value

First press and hold the "Setting" button for 3 seconds to enter the setting state, press the setting button once in the setting state, it will switch a parameter to be set, and press the up and down keys to change the parameter value.
