Description

Automatic sprinkling fire extinguishing system

Technical Field

The invention relates to the technical field of fire early warning, in particular to an automatic watering fire-extinguishing system related to fire early warning.

Background

In many buildings, automatic sprinkler systems have been standard equipped such that when smoke sensors sense the smoke generated by a fire, the sprinkler of the automatic sprinkler system begins to spray water to extinguish the fire. In addition, the electric wire is a common fire hazard, and mainly the electric wire is heated and scalded when the electric power consumption exceeds the electric wire load, and a fire hazard is caused after a long time. However, the existing automatic sprinkler system has no function of early warning when the electric wire is on fire, and the automatic sprinkler system can start to operate only when the electric wire is actually on fire.

Therefore, it is worth those skilled in the art to design an automatic sprinkler system capable of warning the electric wire fire.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1, 2 and 3, fig. 1 is a block diagram of the sprinkler system of the present embodiment, fig. 2 is a schematic view of a wire loop, and fig. 3 is a perspective view of a socket device.

The sprinkler system 1 includes a socket device 10, a sprinkler 20, and a smoke sensor. The outlet device 10 includes a plug 11, a jack 12, a temperature sensor 13, a storage unit 15, a comparison unit 16, and a first wireless communication unit 18. The plug 11 is used for being inserted into an external wire loop 7, the electrical equipment 8 obtains the power provided by the wire loop 7 through the jack 12, and the main material of the plug 11 is copper. The temperature sensor 13 is connected to the plug 11 to obtain a temperature value of the plug 11. The storage unit 15 stores a normal temperature rise rate, a safe temperature rise rate range, and a safe value, and the storage unit 15 is, for example, a flash memory. The comparison unit 16 compares the difference between the actual rising rate of the temperature value of the plug 11 and the normal temperature rising rate. Here, the comparison unit 16 is, for example, a Central Processing Unit (CPU) or a microprocessor unit (MPU). The sprinkler 20 includes a second wireless communication unit 22, and the second wireless communication unit 22 and the first wireless communication unit 18 are communication chips conforming to IEEE 802.11 standard, for example, so that the second wireless communication unit 22 and the first wireless communication unit 18 can communicate with each other. In addition, the sprinkler 20 has two stages of water spraying, which are a first stage water spraying and a second stage water spraying, wherein the second stage water spraying is larger than the first stage water spraying. In this embodiment, the socket device 10 and the sprinkler 20 are located in the same room. In addition, the smoke sensor 30 is adapted to sense smoke and send an activation signal 31 to the sprinkler 20 when smoke is sensed.

Since the wire loop 7 and the plug 11 are both made of copper, the heat conduction rate is very fast, and when the wire loop 7 is energized to start heating the plug 11 will start heating, which will be reflected on the temperature measured by the temperature sensor 13. When the actual rate of rise of the temperature value of the plug 11 exceeds the normal rate of rise of the temperature, this is indicative of a situation in which the power line circuit 7 may have a charge exceeding the load of the power line, which may be a precursor to a fire. Therefore, the comparison unit 16 compares the difference between the actual rising rate of the temperature value of the plug 11 and the normal temperature rising rate, and when the difference exceeds the safe temperature rising rate range recorded in the storage unit 15, the comparison unit 16 commands the sprinkler 20 to start the first stage sprinkling through the second wireless communication unit 22 and the first wireless communication unit 18. In a preferred embodiment, the first stage application of water is, for example, a spray application of water. When the user notices that the water is sprayed from the sprinkler 20, he or she should immediately stop the use of the electrical equipment 8 and ask the professional to check the wire loop 7 to avoid further regret. When the use of the electrical equipment 8 is stopped and the temperature value of the plug 11 falls below the safety value, the comparing unit 16 instructs the sprinkler 20 to close the first stage sprinkling amount through the second wireless communication unit 22 and the first wireless communication unit 18; that is, the sprinkler 20 is no longer sprinkled.

In addition, in the event of a fire on the electrical line, the smoke sensor 30 senses smoke and sends an activation signal 31 to the sprinkler 20. When the sprinkler 20 receives the activation signal 31 from the smoke sensor 30, the sprinkler 20 activates the second stage of water spraying to extinguish or reduce the fire. In this embodiment, the second stage water application rate is the normal water application rate of a typical commercial sprinkler 20.

It should be noted that the reason why the power of the wire loop 7 exceeds the load of the wire may be many, for example, the wire loop 7 is bitten by a mouse to reduce the cross-sectional area of the wire. However, whatever the cause of the power exceeding the load of the electrical line, this will cause the actual rate of rise of the temperature value of the plug 11 to exceed the normal rate of rise of the temperature. Therefore, even if the user cannot visually observe the condition of the wire loop 7, the present invention can determine early whether the wire loop 7 has the problem of aging or corrosion. In addition, the normal temperature rise rate and the safe temperature rise rate range stored in the storage unit 15 may be values obtained by a manufacturer of the outlet device 10 through a plurality of experiments in advance. In addition, the sprinkler system 1 further includes a server 40, the socket device 10 can communicate with the server 40 through the first wireless communication unit 18, and when the manufacturer has the latest experiment value, the normal temperature rise rate and the safe temperature rise rate range stored in the storage unit 15 can be updated synchronously.

In addition, the outlet device 10 further includes a positioning unit 14, the positioning unit 14 is used for positioning a position coordinate of the outlet device 10, and the positioning unit 14 is, for example, a GPS chip or an indoor positioning chip. The wireless communication unit 18 is used to transmit the position coordinates and the temperature value of the plug to the server 40. Thus, if a portable electronic device (e.g., a smart phone) of a user is connected to the server 40 through a network, the user can know the temperature value of the plug 11 and the rate of increase of the temperature value even when the user is not at home.

In addition, the server 40 may also store multiple sets of normal temperature rise rate and safety temperature rise rate ranges for different wire loops 7. For example, the electric wire loop 7 of the kitchen tends to have a high temperature and a high temperature increase rate due to the proximity of the heat source and the high power consumption of the electric wire loop 7. On the contrary, the power consumption in the toilet is low, so the temperature of the corresponding wire loop 7 tends to be low and the temperature rising rate is slow. Therefore, the socket device 10 for kitchen and the socket device 10 for toilet are different in the setting of the normal temperature rise rate and the safe temperature rise rate range. If the user installs the outlet 10 installed in the toilet in the kitchen, since the outlet 10 has the positioning unit 14 and is connected to the server 40 via the network, the server 40 can determine that the installation position of the outlet 10 is changed, and update the normal temperature rise rate and the safe temperature rise rate range of the outlet 10 simultaneously.

The server 40 may further include a module with a big data analysis function, so that the normal temperature rise rate and the safe temperature rise rate of the socket device 10 can be finely adjusted to reflect the real conditions.

In addition, as shown in fig. 3', the automatic power-off device 10 further includes an LED lamp 17, and when the difference between the actual rising rate of the temperature value of the plug 11 and the normal rising rate of the temperature exceeds the safe temperature rise range recorded in the storage unit 15, the comparison unit 16 commands the LED lamp 17 to be turned on.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
