Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
The embodiment of the gas alarm linkage method comprises the following steps:
most of the existing intelligent gas meters use replaceable dry batteries, and after the batteries are removed, valves of the gas meters can be turned off. The invention skillfully utilizes the characteristic of the intelligent gas meter and realizes the purpose of cutting off the gas output by controlling the power supply of the battery. The specific scheme is as follows:
as shown in fig. 1-2, a gas alarm linkage method replaces one dry battery in the existing gas meter with an intelligent battery 1, and the intelligent battery 1 is installed in series with the other dry batteries 2 in the gas meter. The existing gas meter is basically 3 or 4 sections of 1.5V dry batteries. Under a normal state, the intelligent battery normally outputs 1.5V voltage, and the gas meter normally works. When the gas alarm detects that the gas concentration reaches a set value, namely the gas leaks and reaches an alarm condition, a signal is sent to the intelligent battery, so that the intelligent battery 1 does not output voltage. When the intelligent battery 1 does not output voltage, the whole battery pack connected in series cannot normally output voltage, and a valve of the gas meter is closed, so that the purpose of cutting off gas output is achieved.
The method of the invention does not need to reform the original fuel gas pipeline, and the reforming method is simple and easy to operate, does not need professional persons, and has low reforming cost.
In order to implement the method, the gas alarm linkage system comprises a gas meter and a gas alarm, wherein the gas meter is an existing gas meter, the gas meter is provided with a plurality of dry batteries and an intelligent battery, 3 or 2 dry batteries are adopted to be matched with the intelligent battery, and the dry batteries are connected with the intelligent battery in series.
