Today, I will introduce a national invention authorized patent-a gas meter that can remind battery information by SMS. The patent was applied for by Anhui Fusite Intelligent Technology Co., Ltd., and the authorization was announced on March 8, 2017.
Content descriptionThe utility model relates to the technical field of gas meters, and more specifically, to a gas meter capable of reminding battery information by short messages.
Background of the inventionAt present, the IC card gas meters on the market have got rid of the drawbacks of manual meter reading. They use advanced radio frequency card technology to make smart gas meter technology more and more mature. In order to prevent explosions, ordinary IC card gas meters are all battery-powered. And most of the IC card gas meters are powered by dry batteries. Only when the battery energy is exhausted, which is commonly known as "out of power", the user will replace the battery, which brings great inconvenience to the user's life.
After searching, it was found that the existing technology has a variety of gas meter design schemes with battery level reminding function, such as sound alarm type, that is, adding a sound alarm module to the gas meter. When a battery undervoltage is detected, the user is reminded to replace it by sound Battery; for example, Chinese patent number: ZL 201521018812. 5, announcement date: June 15, 2016, the name of the invention is: a household gas meter that can alarm to indicate that there is no power, the application discloses a kind of alarm that can indicate that there is no Household gas meter with electricity. The patented solution can provide alarm reminders, but if the user has Other affairs to deal with at the time, he may turn off the alarm and continue processing the affairs at that time, and then forget to replace the battery, so it is difficult to achieve a more ideal reminder effect during use.
With the popularization of mobile phones, there is also a solution in the prior art to use SMS to remind battery undervoltage. For example, China Patent No. 4, authorization announcement date: February 19, 2014, the application discloses a convenient battery replacement Smart water meter. This patented solution sends the battery undervoltage information directly to the user’s mobile phone, and the information delivery rate is higher. However, people’s lives are currently occupied by various work and news information. There are also more and more push messages in the mobile phone, and users are receiving reminders. After the message, you may forget it quickly and forget to replace the battery. In addition, the program also reminds by directly cutting off water (this program can be understood as cutting off gas), the reminder function should be to remind under the state of ensuring normal work, but this program instead of premature water cut off, its reminder function is also meaningless Therefore, the current program still needs improvement.
Summary of the inventionThe purpose of the utility model is to overcome the shortcomings of the single insufficient battery reminding method in the prior art that it is difficult to achieve a better reminding effect, and to provide a gas meter that can remind the battery information by text messages. The utility model reminds by text messages and lights. In combination, it has a secondary reminder function, which makes it easier to attract users' attention and avoids the inconvenience caused by gas interruption.
In order to achieve the above-mentioned purpose, the technical solution provided by the present utility model is: a gas meter of the present utility model capable of reminding battery information by short messages, including a gas meter body, a voltage detection module, a microprocessor, a GSM communication module, an information receiving terminal and A light alarm module, a battery box with a power supply installed on the gas meter body, the voltage detection module is used to detect the power supply voltage and send the detection signal to the microprocessor; the microprocessor receives the detection signal and communicates via GSM The module sends reminder information to the information receiving terminal; the microprocessor also sends alarm information to the light alarm module.
As a further improvement of the present invention, a SIM card is provided in the GSM communication module, and the SIM card is bound to the information receiving terminal. The light alarm module includes a warning light. When the undervoltage is 10-20%, the warning light flashes at intervals of 0.6 to 0.8s; when the undervoltage is 40-50%, the warning light is 0.2～0. Flashing alarm at intervals of .5s. The warning light includes a red LED light and a yellow LED light. When the voltage is undervoltage, the red LED light and the yellow LED light flash alternately. The GSM communication module is electrically connected with an LED display module for displaying voltage information. The display screen in the LED display module is installed on the gas meter body, and an alarm light is installed on one side of the display screen. The microprocessor is a single-chip microcomputer. The information receiving terminal is a mobile phone.
Compared with the prior art, the technical scheme provided by the utility model has the following beneficial effects: a gas meter of the utility model that can remind the battery information by text messages uses a voltage detection module to detect the power supply voltage, and when the microprocessor judges the voltage When it is insufficient, the GSM communication module sends a reminder to the information receiving terminal, and at the same time controls the light alarm module to work; after receiving the reminder, the user learns that the gas meter battery needs to be replaced, even if the reminder is forgotten when handling other tasks in the middle. After observing the light signal, it will evoke the user's memory, thus avoiding the occurrence of information omission, and having a better reminder effect;
The utility model is a gas meter capable of reminding battery information by text messages. According to the different degree of power supply undervoltage, flashing signals of different frequencies are used to attract the attention of users and facilitate users to replace batteries in time according to different signals; in addition, red, The yellow two lights flash and alarm, which can improve the visibility of the alarm signal and increase the delivery rate of the signal; a display screen is installed on the gas meter body to display the power information in real time. The alarm lamp is installed on the side of the display screen. After the user notices the alarm signal, he will take the initiative to check the remaining power, which is convenient for the user to make a judgment on the current battery usage time, forming a deeper memory, and having a better reminding effect when there is no spare battery.
