Description

Technical Field

[0001] The present invention relates to the field of gas technology, and in particular to an intelligent gas device and a safety monitoring method thereof. Background Art

[0002] With the growing demand for clean energy in modern society, gas, as an efficient, environmentally friendly and widely used energy form, has become an indispensable part of residents' daily life and industrial production. However, the popularity of gas use is also accompanied by safety challenges that cannot be ignored.

[0003] Traditional gas leak detection methods mostly rely on passive response mechanisms after the gas concentration reaches a certain threshold, such as using combustible gas detectors to monitor the gas concentration in the air. Although such methods can identify and alarm to a certain extent, their limitations are: first, the response is delayed, that is, the alarm can only be triggered after the gas leaks and accumulates to a certain concentration, and early warning cannot be achieved; second, the coverage is limited, especially in complex environments or hidden corners, there may be detection blind spots; third, there is a lack of active prevention capabilities, and the risk of gas leaks cannot be reduced from the source.

[0004] What is more serious is that if the gas leak is not discovered and handled in time, it is very easy to cause a fire due to contact with the fire source, which in turn ignites the gas pipeline, causing a more serious secondary accident. This chain reaction not only aggravates the destructive power of the accident, but also increases the difficulty of rescue and the complexity of subsequent handling, posing a major threat to social public safety.

[0005] Therefore, how to innovate gas leak detection technology and realize active monitoring and early warning of gas equipment operation has become a technical problem that needs to be solved urgently. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0021] Figure 1 is a schematic diagram according to one or more embodiments. DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The purpose of the present invention is to provide an intelligent gas equipment and a safety monitoring method thereof to solve the problems existing in the prior art. By monitoring the temperature, gas consumption and the amount of harmful gases, it can ensure that the gas equipment is started in a safe environment, realize active monitoring and early warning of the operation of the gas equipment, and avoid the hazards caused by gas leakage.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1As shown, the present invention provides an intelligent gas device, which can realize intelligent control of gas devices. The gas devices can be devices such as stoves and water heaters that use gas as energy. The intelligent gas device includes a control module and a temperature monitoring module, a gas flow monitoring module, a harmful gas monitoring module and a normally closed flow valve module electrically connected to the control module. The control module has the functions of receiving signals, processing data and sending control signals, and can intelligently control the intelligent gas device. The temperature monitoring module is used to monitor whether the temperature of the gas device is within a reasonable range. For example, the temperature of the gas device or the surrounding environment of the gas device is monitored by a temperature probe. Once there is an overheating or fire, it can be discovered in time and corresponding measures can be taken. The gas flow monitoring module is used to monitor whether the gas consumption of the gas device is within a reasonable range. If the gas consumption exceeds the preset range, it is very likely that a gas leak has occurred. By monitoring the gas consumption, it can be timely determined whether there is a gas leak, thereby stopping the operation of the gas device or prohibiting it from being turned on. The harmful gas monitoring module is used to monitor whether the amount of harmful gas in the gas equipment is within a reasonable range. On the one hand, gas leakage will cause harmful gas overflow, and on the other hand, incomplete gas combustion will also produce harmful gas (such as carbon monoxide). Therefore, by monitoring the amount of harmful gas, it is possible to promptly detect whether there are harmful gases in the gas equipment and its surrounding environment, thereby eliminating the hazards of combustion, explosion or inhalation. The control module is used to process the data transmitted by the temperature monitoring module, the gas flow monitoring module and the harmful gas monitoring module, and send a control signal based on the processing result. The generation of the processing result is based on the judgment of the preset conditions. The normally closed flow valve module is used to receive the control signal and open or close according to the control signal. For example, only when the temperature, gas consumption and harmful gas amount reach or meet the preset conditions, the control module will send a control signal to start the normally closed flow valve module, and the normally closed flow valve module will start, and then it can supply gas to the gas equipment.

[0026] The control module of the present invention is linked to the temperature monitoring module, the gas flow monitoring module, the harmful gas monitoring module and the normally closed flow valve module. According to the monitoring results of the temperature, gas consumption and the amount of harmful gas, the control module can send a control signal to the normally closed flow valve module to ensure that the gas equipment meets the conditions for safe operation, ensure that the gas equipment is started in a safe environment, realize active monitoring and early warning of the operation of the gas equipment, and avoid the harm caused by gas leakage.

[0027] In one embodiment, a ventilation module is further included, which is electrically connected to the control module and can be controlled by the control module. The ventilation module is used to receive a control signal from the control module and is turned on or off according to the control signal. The ventilation module can use intelligently controllable windows, exhaust fans and other equipment.

[0028] In one embodiment, a human monitoring module is also included. The human monitoring module is electrically connected to the control module and can send a signal of whether there is a person to the control module. The human monitoring module is used to monitor whether there is an operator on duty, and the data processed by the control module includes the data of whether there is a person transmitted to the control module by the human monitoring module. In addition, the human monitoring module can also monitor the duration of unattended operation and transmit the data to the control module.

[0029] In one embodiment, the human monitoring module uses a human infrared sensor or a microwave radar sensor to monitor whether there is an operator. Or the operator wears a device that communicates with the human monitoring module, such as Bluetooth communication, based on which it can also be judged whether the monitored person is an adult with operating ability or a child without operating ability, further avoiding danger.

[0030] In one embodiment, a mobile phone signal monitoring module is also included. The mobile phone signal monitoring module is electrically connected to the control module and can send a signal of whether a mobile phone signal is connected to the control module. The mobile phone signal monitoring module is used to monitor whether a mobile phone signal is connected in the house, and then judge whether there are people in the house. The data processed by the control module includes the data transmitted by the mobile phone signal monitoring module. By judging whether the mobile phone signal is connected, the situation where the person is not next to the gas equipment but in other adjacent houses can be identified. Based on this, the situation where the gas equipment cannot be used normally due to the person leaving the gas equipment for a short time and closing the normally closed flow valve module can be avoided.

[0031] In one embodiment, the control module is electrically connected to the temperature monitoring module, the gas flow monitoring module, the harmful gas monitoring module, the normally closed flow valve module, the ventilation module, the human body monitoring module, etc. using wireless communication technology, which can realize wireless communication, reduce the setting of lines, and improve safety and convenience.

[0032] Combine again Figure 1 As shown, the present invention also provides a safety monitoring method, which can be applied to the smart gas equipment as described above, including the following contents:

[0033] Preset temperature values, gas consumption values ​​and harmful gas values ​​in the control module, and set corresponding thresholds;

[0034] Using the control module to determine whether the temperature monitored by the temperature monitoring module is within a threshold range, whether the gas consumption monitored by the gas flow monitoring module is within a threshold range, and whether the amount of harmful gas monitored by the harmful gas monitoring module is within a threshold range;

[0035] If the temperature, gas consumption and harmful gas volume are within the threshold range, the normally closed flow valve module is activated;

[0036] If any one or more of the temperature, gas consumption and harmful gas volume are not within the threshold range, the normally closed flow valve module is closed or not started.

[0037] In one embodiment, the gas flow of the gas equipment has three gears, and the gas consumption values ​​corresponding to each gear are Q1, Q2, and Q3 respectively. The gas consumption used in the specified gear can be monitored, and the threshold is set at ±15% in the control module. The gas flow monitoring module (such as an intelligent flow valve) installed on the gas pipeline monitors the gas consumption and compares it with the gas consumption value set in the control module. If it exceeds the threshold, it means there is a problem. The control module is used to close the normally closed flow valve module, or the ventilation and heat exchange module is opened at the same time. In addition, an alarm is issued to remind personnel to intervene to ensure a safe gas use environment.

[0038] In one embodiment, the temperature of the gas equipment has three gears, and the temperature value corresponding to each gear is T1, T2, and T3. The threshold value is set at ±10% in the control module. The temperature monitored by the temperature monitoring module is compared with the temperature value set in the control module. If the threshold value is exceeded, the normally closed flow valve module is closed, or the ventilation and heat exchange module is opened at the same time, an alarm is issued, and personnel are reminded to intervene to ensure the safety of the gas use environment.

[0039] In one embodiment, an unattended time value is preset in the control module, and a human monitoring module is used to monitor whether there is an operator on duty. If the unattended time exceeds the preset unattended time value, the normally closed flow valve module is closed to avoid gas safety accidents caused by unattended operation.

[0040] In one embodiment, if the closure of the normally closed flow valve module is caused by gas consumption or harmful gas volume exceeding a threshold value, the ventilation module is linked to open to discharge leaked gas or harmful gases generated by incomplete combustion to the outside.

[0041] In one embodiment, the control module is connected to the network, and the status of the gas device can be remotely viewed or the gas device can be remotely controlled through the terminal device.

[0042] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
