In the impression of the author growing up, to say the reminder of home life, the words "anti-power anti-theft anti-gas "is probably the most familiar. In our life, family theft, leakage, and gas leaks already as a few vital life member. From qualifying, I want to also be able to see that we live headache for gas hazards.
Home alarm, gas alarm is early in our lives no more than one home alarm device. It stands to reason, as the biggest hidden alarm measures in our daily lives, it should be the very audience the fishes. But now the application of the current situation is contrary to many people's surprise: the audience equipment is especially deserted, even packed gas alarm device directly reduced to the unwanted situation, in the end is what makes this ought to take the equipment in use at the beginning to suffer such a violent cold front?
Able to "hear" the gas
Speaking of gas, for its application can be said to be active and passive. Active in our daily lives, it is absolutely indispensable fuel. However, for the protection of its security, but we have been not come up with any good way. Although we tried to coal gas "odor" special gas as a warning, but it seems to solve the problem of a gas leak, still did not bring the what substantive harvest.
The emergence of the gas alarm is actually from gas alarm sounds - A reminder of the gas changes since the user is in use, difficult to detect if we help you and then tells you to smell: gas leak it! For a gas alarm device, its core is a gas sensor
, sometimes we turn called "electric nose. This is a unique design resistance device, when the "nose" smell gas, the sensor's resistance force will vary with the concentration of the gas. When the gas reaches a preset level of concentration, the resistance will rise to the critical point of an alarm, so, the sensor will alert prompts, we can "listen" to the gas leak.
Alarm host can achieve linkage with monitoring or control end. The alarm sounds at the same time, you can also automatically start the exhaust device, at the same time close the pipeline valve , the real from the root to control the gas leak. It stands to reason that this configuration has sufficiently advanced and perfected.
Who the gas alarm into a cold front?
Through the above analysis, we can see a small alarm device, will be able to help us solve the big problems. However, why it can solve the problem of gas leakage has been difficult to overcome, but can not overcome the patience of the user?
User frustration
The benefit than gas alarm any link in the chain, the user probably is the biggest benefit of a group, but in which the user, but facing the moment three different situations: "is not used and do not know, know but do not want to , want to use, but does not take. "
Not used do not know
In a district of Chaoyang District, Beijing, an owners moved into a new home for more than three years later, to know as early as before the move in the kitchen, installed a combustible gas. From moving into a new home and now, however, a department does not have similar tips of her, so this device from start to finish and did not play its role, and no one to carry out maintenance and repair. Today, the owners even do not know that this has not worked "the baby pimple" in the end can not make.
Do not want to know
Then do not know, let's talk about the know.
I have seen such a survey, in an interview in the streets of Beijing, there are many users said combustible gas is really practical things. But respondents think that is great, but not if they do not tend to install a lot of attention like. I think that this opinion of the latter on behalf of the aspirations of the majority of users. Is these users afraid to spend money?
As far as I understand now the most simple of combustible gas priced at 200 yuan, but better to not a few hundred dollars. Why do the majority of users prefer to install in the top floor living protective doors and windows for a thousand dollars, not spend two hundred dollars to eliminate the hidden dangers of fire ? I want fluke and that it would not do much psychological is just part of the main concerns about the quality of such products.
Today, the gas alarm market products of varying quality, low-priced products in product prices or even 30 yuan. In this environment , the quality of the product and how to protect? Should consumers choose? All right when detected not, to something when Zhiwangbushang. I am afraid that anyone this money is not so assured.
Want to use does not take
In addition to the two users, many users chose to trust the gas alarm device. Today, however, many users are often faced with combustible gas of the phenomenon of false positives, some alarm, anti-jamming capability is very weak, and even "smell" the vinegar also "exclaimed" themselves. And true to the time of need, but because the application time is too long and lead to equipment failure. Who can calm endure such false positives?
Immature technology , and the subsequent lack of maintenance
Was the bottom line of our security equipment, why carry us so not liking applications? It is understood that this is still a great relationship with the immaturity of the combustible gas technical. As mentioned above, the combustible gas of the core lies in its sensor means. For the technical characteristics of the sensor, with the passage of time and changes in the environment, though not been used, but its sensitivity will slowly reduce the sensing point of the device is also changed. Under normal circumstances, the validity of the sensor manufacturer
in about 5 years.
For odor sensing technology may be one for some time, but for an ordinary family, five years will happen several serious gas leak it? So this is also the number to the user a feeling of no access, if often false positives, it really user seen as clutter things up.
However, such a device is very short-lived "In our eyes, in the after-sales maintenance, but it is difficult to obtain a thoughtful service. Lot of equipment after installation on the end of the story ", no professionals to look over, even the above mentioned users do not know that this equipment. Even if the user wants to repair, have a very cumbersome someone to spend the cost of a repair, and then almost "calm, waiting for the remaining time. In this way it seems, was abandoned by the user is not surprising.
Management department: multi-less attitude
Since the applications, we have to face so many problems. If a system of management of related products is undoubtedly no better thing. Management sector to face the current situation, however, is who will take the lead to do this thing, who would be responsible for the problems faced by these things. In the face of such a large number of applications related equipment, in the face of technology is still immature. Who willing to step into this piece of "muddy water"? As a result, the gas alarm device up as a property company in the beginning, and then the back office to its own devices in the publicity himself a gimmick or merit.
As the security of our lives, the combustible gas present this is all an integral part of home alarm tool. But the publicity is not in place of vendors, technical defects and all recognition, so that the gas alarm quite lonely. This can not be Zhiyuan users can not just blame technology, but can not be attributed solely to administrative departments. We now also only hope that in the day-to-day life, public safety awareness to higher technology again perfect stronger sense of responsibility of the departments concerned, the combustible gas can truly play its role we really need security.
