Alarm digitization trend becomes inevitable

An alarm is an electronic product that alerts or warns us to take certain actions in the form of sound, light, and air pressure to prevent or prevent the consequences of an incident. With the advancement of science and technology, mechanical alarms are increasingly being replaced by advanced electronic alarms. They are often used in areas such as system failures, safety precautions, transportation, medical aid, emergency response, and induction detection, and are closely related to social production. Inseparable. As an important part of the anti-theft alarm system, alarms need to be more intelligent, digital, and technological.

The development trend of the alarm system market With the development of science and technology and the improvement of people's awareness of security, the intelligentization of the security industry has become an important trend. The alarm system, as a subsystem in the security system, also plays an important role in various industries. However, burglar alarms in the technological innovation of the security industry are still relatively backward.

The communication link in the alarm system generally includes networking between the alarm detector and the alarm controller, and networking of the alarm controller and the control center. In the actual construction deployment process, in order to be able to flexibly match the number and wiring of the detectors, most of the detectors and alarm controllers still use traditional switch signal transmission, and the connection between the alarm controller and the control center is whether the system is stable. The key to robust and flexible expansion.

In the market, the construction market is also an important reason for the lagging development of the alarm system industry. In the ten years of rapid development of smart buildings, the alarm system was first introduced into residential construction. However, with the technical revolution of the video intercom system, the alarm system was gradually squeezed out of the residential market, which also led to the gradual reduction of the industry's share in the residential market, affecting the technical progress of the industry.

Especially in the alarm zone settings, online programming, wireless alarm, etc., the alarm system has greatly improved, basically using a mixed alarm zone and the means of online programming and zone settings through the computer, in the past by the alarm keyboard The phenomenon of in-line programming and zone setting input no longer appears. The most critical of the current alarm system is the innovation of various detectors, and the technical renewal of the detector is more difficult than that of the control panel. This requires a combination of multi-disciplinary technological innovations. Such as optical, microwave, various sensors, special sensor research and development.

The alarm system has been moving forward with a steady pace in the security industry. The areas of rapid technological innovation are mainly the changes of various detectors. With the continuous increase of market demand and the continuous development of product technology, the function of the network alarm host gradually expands, and there are also people that the future of the alarm host will gradually develop toward the direction of the intelligent terminal, the product not only has the general alarm function, but also has information release Receiving function, that is, in addition to issuing alarm information, the alarm center can also publish the contents of the property management and various notices to the host.

Take the gas alarm in the gas alarm as an example, we simply analyze the application of gas alarms in the industry, the market popularity and reasons, and the main points of product use.

The market penetration rate of gas alarms is not high. The use of gas has become very popular in modern life. While gas brings us convenience, we also need to pay attention to the safety of gas use. According to an industry source in Beijing, Beijing has more than 4 million natural gas users, but no more than 500,000 users have installed gas alarms. So, what causes the low penetration of gas alarms? The author summarizes the following three points:

1. Insufficient awareness of residents' safety protection Many residents have a weak sense of safety protection. There is a sense of chance. They believe that there are no problems with the installation of gas alarms for so many years, and there is no need to spend money on them. They one-sidedly believe that gas alarms are merely pattern products and have little effect on gas safety protection.

2, poor quality products disrupt the market China Institute of Metrology senior engineer, engaged in gas alarm detection years Yong Yonghua said that there are many low-cost low-quality alarm on the market. Because it is used at home, manufacturers will consider the user's affordability, so try to reduce costs, it is impossible to use a good quality and expensive sensors, and the quality of the sensor directly determines the quality of the alarm. The newspaper did not report that poor quality products that did not indiscriminately report affected the public’s confidence in the industry’s products.

3. The government is not actively promoting China currently does not require national mandatory regulations for the installation of domestic gas alarms. A few local governments are just starting to require mandatory installation of gas alarms.

The Xining Public Security Technology Prevention Management Measures promulgated by the Xining Municipal Government of Qinghai Province require that: “The construction of public security technical protection facilities for urban residential houses shall be incorporated into the residential construction plan, and shall be designed, constructed and accepted simultaneously with the residential project. At the same time, it was put into use." Article 47 of the Harbin Gas Management Regulations stipulates: "In the case of using pipeline gas for new construction, reconstruction, or expansion projects, the construction unit shall install a gas alarm, and its cost shall be included in the construction cost." , Advocates users who have used pipeline gas to install gas alarms.

The alarm early warning function is difficult to achieve. The convenience of the gas has been favored by many families, but gas leaks, poisoning and other incidents have occurred. According to a city survey, there are 30% of gas users do not install gas alarms, and some users are not scientifically installed. Gas Group reminds that gas alarms cannot be installed in the kitchen. It is best installed in the aisles leading to the bedroom. The height is about two meters from the ground. It is best to install two alarms in the houses of larger residents to ensure family members. Safety.

Gas is one of the most commonly used gas among residents, and its convenience is recognized by many residents. However, safety issues are always worrying. Gas accidents often occur. Gas Group conducts large-scale safe gas campaigns and household inspections in response to policies. According to investigations, not only did the city's gas users not install gas alarms, even the installed users were not scientific, some were too close to the kitchen, causing the gas to always alarm, and some were trapped in plastic bags to prevent fumes. The result is lost alarm.

For this reason, the city gas expert suggested that the alarm should be installed in the aisle. The alarm is the last line of defense against gas accidents, and it is also the most effective way to avoid accidents. It is understood that many people use alarms and feel that this thing is always an alarm and it is not easy to use.

In addition, the alarm is always an alarm. It is very likely that the installation location is too close to the kitchen. When the residents are cooking, the explosion pan causes fumes and cooking gas, which may make it alarm, because the general alarm is mainly sensitive to carbon monoxide, but There are also some flammable gases in the fried cooking fumes, so it will alarm.

The gas alarm cannot be installed in the kitchen. It is best to be installed in the aisle leading to the bedroom. The height is about two meters from the ground. It is better to install two alarms in the homes of residents with larger houses. Because of the leakage of outdoor pipelines and the leakage of gas from other households, gas may enter the residents' homes through the sewers. If they are installed in the kitchen, they may not be detected.

In the future, the alarm industry will be integrated with digital detectors, all-digital network platforms, multi-angle control methods, integration with access control systems, intercom systems, and monitoring systems, and ultimately integrated with the computer as an integrated security system. All the security subsystems are integrated into the integrated alarm system under the computer management platform. As an important part of the alarm system, the future development of the alarm will follow the trend of digitalization of the system. Various types of alarms will continue to be accepted by people and will continue to be popularized in applications.
