Referring to fig. 2, fig. 2 is a data processing method of a gas meter with an embedded program in an NB-IoT communication module. It should be noted that the data processing method for the gas meter with the NB-IoT communication module embedded program according to the embodiment of the present invention is not limited to the steps and the sequence in the flowchart shown in fig. 2, and the steps in the flowchart may be added, removed, or changed according to different requirements. As shown in fig. 2, the data processing method of the gas meter with the NB-IoT communication module embedded with the program includes:
and S10, starting a timer to start timing, and when the timing time reaches the overtime time, awakening the NB-IoT communication module in the gas meter in the low power consumption state by the timer.
In this embodiment, the NB-IoT communication module is in a low power consumption state, thereby saving power. The NB-IoT communication module 9 is triggered to operate, that is, the NB-IoT communication module 9 is switched from the low power consumption state to the normal operation state, and there are two ways, one is an external interrupt to wake up the NB-IoT communication module 9 to switch to the normal operation state, and the other is an timeout interrupt of the timer 6 (the time length of the timer 6 reaches a predetermined time, for example, the timeout time) to wake up the NB-IoT communication module 9 to switch to the normal operation state, as shown in fig. 3. When the NB-IoT communication module 9 is woken up, it starts to process various tasks to implement various functions.
The timer timeout interrupt wakes up the NB-IoT communication module 9, specifically:
after the intelligent gas meter is powered on, the module firstly enables and initializes related modules and interfaces such as an NB modem, an intelligent gas meter RAM, a storage module 7 and the like in an NB-IoT communication module 9 embedded with an intelligent gas meter function, after initialization, each module enters a dormant state, when the photoelectric direct-reading gas meter is used, the interrupt time of a timer 6 is set, after the timer 6 is interrupted, a meter head direct-reading interface program fetches data in a mechanical direct-reading device, and the interrupt time of the timer 6 can be set wirelessly or through program initialization. When the program is interrupted by the timer 6, the related functions are executed according to a certain time interval, whether the time of the interruption time is the same as the preset function time or not is compared, if the time of the interruption time is the same as the preset function time, the event zone bits of the related functions are set, and after the interruption is skipped, the main function can complete the corresponding event function according to the zone bits.
And S20, switching the NB-IoT communication module into a normal working state, acquiring the gas consumption information stored in the storage module in an IIC communication mode, and sending the gas consumption information to the Internet of things platform.
In this embodiment, when the time reaches the preset uploading time, the NB-IoT communication module is switched to a normal working state, the NB-IoT communication module 9 is powered on when being awakened, and executes an initialization program, and the MCU chip then uploads a piece of data to the internet of things platform through the corresponding modem by using the communication protocol. For example: and acquiring the gas consumption information stored in the storage module in an IIC communication mode, and sending the gas consumption information to the Internet of things platform.
If the program detects abnormal phenomena such as undervoltage, reverse flow and the like, the program gives an alarm and uploads a piece of data to remind a user through the NB-IoT communication module 9. When background information is received every time, the received information contains calendar time information, and an internal clock of the intelligent gas meter can be automatically checked, so that the accuracy of the calendar clock of the intelligent gas meter is guaranteed. Meanwhile, the system performs system internal state diagnosis once every other period of time during the interruption of the timer 6, and judges whether each functional unit is normally started and whether each expansion port is applied. If some functional units are abnormal, the MCU chip uploads a piece of data to the cloud background through the communication protocol to inform relevant personnel of maintenance operation.
And S30, the NB-IoT communication module receives the result fed back by the Internet of things platform, and switches the result into a low power consumption state after storing the result so as to wait for being awakened next time.
In this embodiment, the NB-IoT communication module receives the result fed back by the internet of things platform, and stores the data in the flash memory, which is used as a reference, and is also convenient for calling and calculating. When the task is detected to be completed, the NB-IoT communication module is automatically switched to a low power consumption state to wait for being awakened next time, so that the electric quantity is intelligently saved, the consumption is reduced, and the data processing efficiency is improved.
Waking up the NB-IoT communication module by external interruption, specifically: when detecting that the user uses the gas to generate an interrupt signal, the NB-IoT communication module is awakened to be switched into a normal working state; the NB-IoT communication module acquires and executes a task to be executed so as to realize the function of metering and pricing, and stores related data after metering and pricing in a storage module; and when the NB-IoT communication module finishes the task to be executed, switching to a low power consumption state to wait for being awakened next time.
That is, when the pulse counting gas meter is used, the program starts an external interrupt detection mode, and when a pulse signal is received, the program is interrupted, and the flow rate is calculated through the interrupted state. After the flow is obtained, the flow information is uploaded to an internet of things platform in a timing mode, meanwhile, the data storage program can store the usage information in the data storage module, the information can be stored for one month, after the intelligent module finishes data acquisition and storage, the NB debugging demodulator initialization program starts to be executed, and meanwhile, the NB-IoT network is used for uploading the acquired usage information to the internet of things platform, such as a cloud platform.
For example: and when the gas consumption of the user is detected, an interrupt signal is generated, the NB-IoT communication module is awakened according to the interrupt signal, so that the NB-IoT communication module has the function of metering and pricing, and the accumulated quantity, the current actual flow and other data are stored in the storage module.
Furthermore, the program can also set events according to requirements, the events can be configured as data uploading, under-voltage alarming, stealing alarming, ultra-small flow alarming, reverse flow alarming and the like, and the events can be detected by running the program when timing interruption or external interruption such as gas interruption occurs. For example, after the timer interrupt occurs, the program may start to detect whether there is under-voltage, whether there is time for data upload, etc. The event flag bit is changed by the timer interrupt or the external interrupt, and the jump-out interrupt carries out related event operation according to the flag bit after the change. When the NB-IoT communication module 9 is interrupted and awakened, the type of the interrupt is first determined, if the interrupt is external, then the event flag bit of the related function is set by determining which specific port causes the interrupt, and after the interrupt is dropped, the main function will complete the corresponding event function according to the flag bit. The functions triggered by external interruption mainly include a battery power detection function of the power module 2, a gas meter function of a mechanical pulse counting gas meter, and a pulse counting function. If all the functional units are normally started, the module enters a dormant state and a low power consumption state and starts a timer 6, when the NB-IoT communication module 9 monitors a sent message or awakening time set by a program reaches, the NB-IoT communication module 9 can be awakened, when the NB-IoT communication module 9 is awakened, the NB-IoT communication module is in a normal working state, all the working units start to work, wherein data are transmitted to the intelligent gas meter through an upper computer or an Internet of things platform to be subjected to valve control, the intelligent gas meter extracts data to be calculated and transmits the data to a data interface, and the data are transmitted to the upper computer through a data line through modulation, filtering and the like to be analyzed.
In summary, the application discloses a gas meter with an embedded program of an NB-IoT communication module and a data processing method. The NB-IoT communication module is a special NB-IoT communication module for a gas meter, which integrates the mechanical pulse counting gas meter of the gas meter, a direct reading program, a pulse counting module and a program, an expandable interface and a program, a valve driving module, a step gas price charging unit, a timer, a liquid crystal display screen, an input module and the like with the NB-IoT communication function into a MCU chip, saves an external MCU, obviously saves the cost, and ensures that the product has higher competitiveness in market competition; this application has convenient to use, and the low power dissipation is small, and the reliability advantage such as higher all has stronger practical meaning to intelligent gas table field, has increased the accuracy of flow measurement through infrared sensor and strapping table.
