[0039] A main control module, used for receiving and processing the read data from the first meter reading module and the second meter reading module;

[0040] A temperature measurement module, including a temperature sensor for collecting ambient temperature data, the collected data of the temperature sensor is sent to the main control module; and

[0041] The data transmission module is used to remotely transmit the data processed by the main control module to the cloud server to realize remote storage, analysis and processing of data.

[0042] In the above, if Figure 2 and 3 As shown, the first RS-485 interface circuit and the second RS-485 interface circuit both use wired methods to collect data from the building heat meter and the indoor temperature regulator; the M-BUS interface circuit can implement the wireless data collection solution of the first meter reading module through a wireless data repeater; Figure 4 As shown, the RF wireless communication module can establish communication with the indoor temperature regulator to implement the wireless data collection solution of the second meter reading module.

[0043] Specifically, Figure 5As shown, the M-BUS interface circuit includes an RS-232 conversion chip and transistors Q1, Q2, Q3, Q4, and Q5. The emitter of the transistor Q1 is connected to one end of resistors R31 and R32 and a +12V power supply. The base of the transistor Q1 is connected to the other end of the resistor R31 and the collector of the transistor Q5. The other end of the resistor R32 is connected to the base of the transistor Q5 and the collector of the transistor Q4. The collector of the transistor Q1 is connected to the anode of the diode D9, the base of the transistor Q2, and one end of the resistor R40. The emitter of the transistor Q2 is connected to the cathode of the diode D9 and is connected to the RM pin of the RS-232 conversion chip through a resistor R34. The collector of the transistor Q2 is connected to one end of resistors R33, R36, R41, R42, and R43, the other end of R40. The other end of the resistor R36 is connected to the base of the transistor Q3, the anode of the diode D7 and the TM pin of the RS-232 conversion chip, the emitter of the transistor Q3 and the cathode of the diode D7 are grounded, the collector of the transistor Q3 is connected to the emitter of the transistor Q4 and the other end of the resistor R41 through the resistor R37, the base of the transistor Q4 is connected to the anode of the diode D8 through the resistor R38 and is grounded through the resistor R39, the emitter of the transistor Q5 is connected to the other end of the resistor R33 and the first end of the interface J5, the other end of the resistor R42 is connected to the negative electrode of the indicator light D12, the other end of the resistor R43 is connected to the anode of the indicator light D12 and the second end of the interface J5, and the output end of the RS-232 conversion chip is connected to the main control module.

[0044] When the first meter reading module needs to receive data from the heat meter of the building, its wireless data collection scheme is as follows: the heat meter transmits differential signals through its M-BUS interface. These signals contain heat data and other related information, such as device address, data type, etc. The M-BUS interface circuit captures these differential signals through the wireless data repeater. The differential signals are sent to the M-BUS interface circuit through interface J5 for signal amplification and shaping processing to ensure that the signal maintains sufficient strength and clarity during transmission. The signal processed by the M-BUS interface circuit is sent to the RS-232 conversion chip, which is used to convert the TTL logic level signal into the RS-232 level signal. Specifically, the RS-232 conversion chip uses the MAX232AEJE (16) integrated circuit. The MAX232AEJE is a low-power, dual-channel driver / receiver, such as Figure 6 As shown in the figure, in its pin configuration, the TM (Transmit Mode) and RM (Receive Mode) pins are used to control the working mode of the module:

[0045] TM pin: The TM pin is used to control the module's transmission mode. When the TM pin is connected to a low level (usually grounded), the module enters the transmission mode. In this mode, the driver part of the MAX232AEJE is activated, which can convert the TTL level signal into an RS-232 level signal and send it out through the T1OUT and T2OUT pins;

[0046] RM pin: The RM pin is used to control the receiving mode of the module. When the RM pin is connected to a low level, the module enters the receiving mode. In this mode, the receiver part of the MAX232AEJE is activated and can receive RS-232 level signals from the R1 IN and R2 IN pins and convert them into TTL level signals.

[0047] In the above, if Figure 7-9 As shown in the figure, the main control module uses a single-chip microcomputer model STC11F32XE (LQPF44), and the single-chip microcomputer is peripherally provided with a serial port module and a clock circuit. The single-chip microcomputer has an 8-bit CPU, based on the 8051 core, providing high processing power and rich peripheral interfaces. The serial port module of the single-chip microcomputer is used to realize serial communication, and can be connected to RS-232, RS-485 and M-BUS interface circuits to realize data exchange with external devices. At the same time, the single-chip microcomputer is also connected to the LCD display through the serial port to display the system status, data and other important information in real time. The LCD display provides a user-friendly interface, allowing users to intuitively monitor and control the system. The single-chip microcomputer is also provided with a function key module, allowing users to input commands or instructions to the system through physical buttons, such as power on, power off, adjust settings, start specific functions, etc.

[0048] The STC11F32XE (LQPF44) single-chip microcomputer is the core processing unit of the system, integrating data acquisition, processing and display functions. It communicates with external devices through the serial port, processes data from the heat meter and the temperature regulator, and transmits the processed data remotely to the cloud server through the data transmission module. Among them, the data transmission module is a GPRS communication module. The model selected in this embodiment is MC52i, which supports GSM / GPRS wireless communication technology, so that the STC11F32XE (LQPF44) single-chip microcomputer can remotely transmit data to the cloud server, realizing remote storage, analysis and processing of data.

[0049] In the specific settings, the intelligent monitor also provides a PC programming module, such as Fig.10As shown in the figure, the PC programming module includes an ISP programming interface chip and a USB interface. The ISP programming interface chip exchanges data with the main control module through the serial port and establishes a connection with the computer through the USB interface. The ISP programming interface chip uses the PL2303HX serial interface chip. The PC programming module is not only used for initial programming, but also for subsequent system maintenance and upgrades. Users can update the microcontroller program at any time to fix errors, add new functions or improve performance. The PC programming module provides the system with flexible programming and data exchange capabilities, making system development and maintenance more convenient and efficient.

[0050] In summary, the intelligent monitor of the utility model can read the real-time data of the heat meter and the temperature regulator at the same time, and has both wired and wireless data collection methods. This design not only enhances the flexibility of data collection, but also can adapt to various monitoring environments. The main control module uses the STC11F32XE (LQPF44) single-chip microcomputer, which has powerful data processing capabilities and can receive, process and analyze data from the two meter reading modules. The processed data is sent to the cloud server through the data transmission module, providing users with an efficient, reliable and easy-to-manage heat and temperature data monitoring solution, which is suitable for a variety of application scenarios such as smart buildings and smart homes. At the same time, it provides a simple and easy-to-use user interaction interface and convenient remote programming capabilities, which greatly simplifies the configuration and maintenance of the equipment.
