Description

Technical Field

[0001] This invention belongs to the field of environmental parameter monitoring technology, specifically relating to an integrated transmitter system for collaborative processing of multi-protocol sensor data. Background Technology

[0002] Environmental parameter monitoring is widely used in industrial production, agricultural breeding, warehousing and logistics, equipment operation and maintenance, and environmental safety management. To ensure product quality, equipment safety, biological growth environment, and the stability of on-site control processes, it is usually necessary to collect on-site environmental parameters in real time through sensors such as temperature, humidity, pressure, and gas concentration, and transmit the collected results to programmable logic controllers, host computers, industrial gateways, or cloud platforms. With the increasing digitalization and Internet of Things (IoT) in industrial sites, transmitters not only need to complete basic data acquisition and signal conversion, but also need to be compatible with various application requirements such as different types of sensor inputs, digital communication outputs, analog outputs, alarm control, and local display.

[0003] Existing environmental parameter transmitters are mostly designed based on a single communication interface or a single output method. Some products only provide an RS485 digital communication interface, while others only provide one analog output. Therefore, when the field control system needs to connect to both an old programmable logic controller that only accepts 4-20mA signals and a digital monitoring system, an additional independent signal conversion module is usually required, increasing system complexity and field deployment costs. At the same time, existing relay output transmitters mostly use fixed over-limit alarm logic, resulting in an inflexible correlation between relay action and alarm events such as temperature and humidity. Some products also lack hysteresis mechanisms, which can easily cause frequent jumps near the critical point, leading to frequent start-stop of external equipment such as fans and heaters. Furthermore, some products have a fixed 4-20mA output range, making it difficult to flexibly adjust the physical range corresponding to the analog output according to different measurement ranges, affecting field adaptability.

[0004] In addition, the digital communication, analog output, relay control, and display refresh in existing transmitters usually operate as relatively independent functional processes, lacking a unified data collaborative processing mechanism for multiple output channels. The corresponding sensor data is prone to forming different data update paths during the processes of acquisition, calibration, alarm judgment, analog output, communication register refresh, and field display. This leads to the risk of asynchrony between communication read values, analog output values, alarm status, and display status, which is not conducive to users quickly understanding the correspondence between digital registers and analog quantities and the relay linkage logic, nor is it conducive to rapid field deployment and subsequent maintenance.

[0005] Therefore, there is an urgent need for an integrated transmitter system that can collaboratively process multi-protocol sensor data, in order to solve the shortcomings of existing transmitters in terms of unified access to multi-protocol sensors, unified management of operating data, collaborative updating of multiple output channels, alarm hysteresis linkage control, and adaptability to complex field deployments. Summary of the Invention

[0006] In view of this, the present invention proposes an integrated transmitter system for collaborative processing of multi-protocol sensor data, which is applied to the field of environmental parameter monitoring technology. It solves the technical problems of existing transmitters in terms of unified access of multi-protocol sensors, unified management of operating data, collaborative updating of multiple output channels, alarm hysteresis linkage control, and adaptability to complex field deployment.

[0007] To achieve the above-mentioned technical objectives, the specific technical solution adopted by the present invention is as follows: An integrated transmitter system for multi-protocol sensor data collaborative processing includes a microcontroller module, a sensor interface module, a data collaborative processing module, a communication output module, an analog output module, a linkage control module, and a display control module. The data collaborative processing module is located within the microcontroller module and includes a protocol parsing unit, a calibration processing unit, and a runtime data structure. The protocol parsing unit receives sensor data acquired via different communication protocols input through the sensor interface module and converts the sensor data acquired via different communication protocols into a unified data format. The calibration processing unit performs calibration offset processing on the sensor data acquired via the unified data format. The sensor data after calibration offset processing is written into the same runtime data structure. The microcontroller module has a main monitoring loop, which includes a sensor acquisition update segment, a runtime data update segment, a communication register refresh segment, an analog output refresh segment, an alarm judgment segment, and a display refresh segment.

The communication register refresh segment, analog output refresh segment, alarm judgment segment, and display refresh segment respectively form communication register data, analog output data, alarm status data, and display refresh data based on the same runtime data structure.

[0008] Furthermore, the alarm judgment segment calls the alarm upper limit, alarm lower limit, upper limit hysteresis value, and lower limit hysteresis value. It compares the sensor data in the runtime data structure with the alarm upper limit, alarm lower limit, upper limit hysteresis value, and lower limit hysteresis value to obtain alarm status data. The linkage control module includes a relay output circuit and an optocoupler output circuit. The alarm status data is transmitted to the relay output circuit and the optocoupler output circuit.

[0009] Furthermore, it also includes a real-time clock module, which is connected to the microcontroller module. The real-time clock module outputs time information to the microcontroller module. The time information is combined with the sensor data in the runtime data structure to form time-stamped sensor data. The microcontroller module forms data frames according to the sensor channel sequence. The data frame includes a frame header, sensor data, and a frame tail. Different sensor data occupy the corresponding data transmission time period in the data frame in sequence.

[0010] Furthermore, the sensor interface module includes at least two of the following: IIC sensor interface, SPI sensor interface, and UART sensor interface. The protocol parsing unit performs protocol parsing on at least two of the following: IIC protocol data, SPI protocol data, and UART protocol data.

[0011] Furthermore, the communication output module includes a Modbus register mapping unit and a communication interface unit. The communication register data formed by the communication register refresh segment is written to the Modbus register mapping unit. The communication interface unit includes at least one of an RS485 / RS232 transceiver, an Ethernet interface, a WIFI module, and a wireless communication module.

[0012] Furthermore, the analog output module includes a DAC module, a conditioning amplifier circuit, and a voltage-to-current conversion module. The DAC module is connected to the microcontroller module, the conditioning amplifier circuit is connected between the DAC module and the voltage-to-current conversion module, and the voltage-to-current conversion module outputs a 4-20mA current transmission signal.

[0013] Furthermore, the display control module includes a cascaded shift register, a digital tube display circuit, and an LED indicator circuit. The cascaded shift register includes a first shift register and a second shift register. The serial data input terminal, shift clock terminal, and latch clock terminal of the first shift register are respectively connected to the microcontroller module. The serial data input terminal of the second shift register is connected to the cascaded output terminal of the first shift register. The parallel output terminals of the first shift register and the second shift register are respectively connected to the digital tube display circuit and the LED indicator circuit.

[0014] Furthermore, it also includes a parameter setting module and a storage module. The parameter setting module includes a button setting unit and an external configuration communication unit. The button setting unit is connected to the microcontroller module, and the external configuration communication unit is connected to the microcontroller module through an RS485 / RS232 transceiver, an Ethernet interface, or a WIFI module. The configuration parameters generated by the parameter setting module are written to the storage module.

[0015] Furthermore, the storage module includes an EEPROM, which is connected to the microcontroller module. The EEPROM stores sensor configuration parameters, communication configuration parameters, alarm thresholds, display configuration parameters, and linkage configuration parameters.

[0016] Furthermore, it also includes a power supply module, which is connected to the microcontroller module, sensor interface module, communication output module, analog output module, linkage control module, and display control module. The power supply module includes a first power interface, a second power interface, a rectifier-buck module, a buck module, a charging control circuit, a backup battery, and a voltage detection circuit.

[0017] The data collaborative processing module in this invention converts sensor data collected via different communication protocols input through the sensor interface module into a unified data format. After calibration offset processing, it writes the data into the same runtime data structure. In the main monitoring loop, the microcontroller module uses this runtime data structure as a unified data basis to form communication register data, analog output data, alarm status data, and display refresh data. This ensures that the communication output module, analog output module, linkage control module, and display control module operate around the same data source. Sensor data from different protocol sources are uniformly organized and calibrated before entering each output channel, eliminating the need to establish separate independent data processing paths. This results in a unified data correspondence between digital communication output, analog output, alarm linkage, and local display.

[0018] By adopting the above technical solution, the present invention can also bring the following beneficial effects: This invention provides an integrated transmitter system for multi-protocol sensor data collaborative processing. By setting a data collaborative processing module within the microcontroller module, sensor data acquired from different communication protocols is converted into a unified data format by the protocol parsing unit, and then calibrated and offset processed by the calibration processing unit and written into the same runtime data structure. Communication register data, analog output data, alarm status data, and display refresh data are all formed around the runtime data structure, avoiding the separate operation of digital communication output, analog output, alarm linkage, and local display based on different data paths. This reduces the risk of data asynchrony between multiple output channels and has the advantages of good consistency in multi-protocol data processing, strong collaboration among multiple output channels, and convenient on-site debugging and maintenance.

[0019] 2. The present invention provides an integrated transmitter system for collaborative processing of multi-protocol sensor data. It loads time stamps onto sensor data via a real-time clock module and combines the frame header, sensor data, and frame tail to form a data frame. This facilitates the organization and tracing of multi-channel sensor data according to channel order. Alarm status data is generated using alarm upper limit, alarm lower limit, upper limit hysteresis value, and lower limit hysteresis value. The relay output circuit and optocoupler output circuit operate based on the alarm status data, reducing frequent switching caused by data fluctuations near the alarm threshold. Display refresh is achieved through a cascaded shift register in conjunction with a digital tube display circuit and an LED indicator circuit, reducing the occupancy of the microcontroller module's input / output ports. This system offers advantages such as strong data traceability, stable alarm linkage, low resource consumption for display control, and high reliability of on-site display.

The data collaborative processing module is located within the microcontroller module and includes a protocol parsing unit, a calibration processing unit, and a runtime data structure. Sensor data acquired using different communication protocols is input to the microcontroller module via the sensor interface module. The protocol parsing unit receives the sensor data acquired using different communication protocols input via the sensor interface module and converts the sensor data acquired using different communication protocols into a unified data format. The calibration processing unit performs calibration offset processing on the sensor data acquired using the unified data format, and the sensor data after calibration offset processing is written into the same runtime data structure. The runtime data structure serves as a data collaboration carrier within the microcontroller module, used to receive the sensor data after protocol parsing and calibration offset, enabling the communication output module, analog output module, linkage control module, and display control module to perform subsequent processing around the same data source.

[0029] like Figure 3 As shown, the microcontroller module has a main monitoring loop. After the system powers on, the microcontroller module initializes the sensor interface module, communication output module, analog output module, linkage control module, display control module, real-time clock module, storage module, and parameter setting module, and loads sensor configuration parameters, communication configuration parameters, alarm thresholds, display configuration parameters, and linkage configuration parameters. After initialization, the microcontroller module enters the main monitoring loop, which includes a sensor acquisition update segment, a runtime data update segment, a communication register refresh segment, an analog output refresh segment, an alarm judgment segment, and a display refresh segment. After entering the main monitoring loop, the microcontroller module determines whether cloud platform forwarding processing is required. If cloud platform forwarding processing is required, the microcontroller module interacts with the cloud platform via the WIFI module or wireless communication module. If cloud platform forwarding processing is not required or has been completed, the microcontroller module determines whether an event has been triggered. If an event has been triggered, the microcontroller module switches to the corresponding event processing, and returns to the main monitoring loop after the event processing is completed.

[0030] In the sensor acquisition and update segment, the microcontroller module receives sensor acquisition data from different communication protocols through the sensor interface module. In the runtime data update segment, the protocol parsing unit converts the sensor acquisition data from different communication protocols into a unified data format. The calibration processing unit performs calibration offset processing on the sensor acquisition data in the unified data format. The runtime data update segment updates the sensor data after calibration offset processing to the same runtime data structure. In the communication register refresh segment, analog output refresh segment, alarm judgment segment, and display refresh segment, the microcontroller module forms communication register data, analog output data, alarm status data, and display refresh data respectively based on the same runtime data structure.

[0031] In the alarm judgment section, the microcontroller module calls the alarm upper limit, alarm lower limit, upper limit hysteresis value, and lower limit hysteresis value, comparing the sensor data in the runtime data structure with these values ​​to obtain alarm status data. The linkage control module includes relay output circuits and optocoupler output circuits. The alarm status data is transmitted to the relay output circuits and optocoupler output circuits, causing them to operate according to the alarm status data. The relay output circuit is suitable for connecting to fans, heaters, or other external control equipment, while the optocoupler output circuit is suitable for connecting to low-current control equipment. By setting the upper and lower limit hysteresis values, frequent output switching caused by fluctuations in sensor data near the alarm threshold can be reduced.

[0032] like Figure 4 As shown, the present invention also includes a real-time clock module connected to the microcontroller module. The real-time clock module includes an RTC and a coin cell battery. The RTC outputs time information to the microcontroller module.

The microcontroller module forms data frames according to the sensor channel sequence. Each data frame includes a frame header, sensor data, and a frame tail. Different sensor data occupy corresponding data transmission periods in the data frame sequentially. Sensor 1 data occupies 8 clock cycles, sensor 2 data (including sensor 2 data 1 and sensor 2 data 2) occupies 16 clock cycles, and sensor n data occupies 8 clock cycles. The coin cell battery is used to maintain RTC operation when the external power supply is disconnected.

[0033] like Figure 2As shown, the display control module includes a cascaded shift register, a digital tube display circuit, and an LED indicator circuit. The cascaded shift register includes a first shift register IC1 and a second shift register IC2.

The cascaded output terminal Q7 of the first shift register IC1 is connected to the serial data input terminal SER of the second shift register IC2. The parallel output terminal of the first shift register IC1 is connected to the segment selection terminals A, B, C, D, E, F, G, and DP of the digital tube display circuit via resistors. Part of the parallel output terminal of the second shift register IC2 is connected to the bit selection terminals DGT0, DGT1, DGT2, and DGT3 of the digital tube display circuit. Another part of the parallel output terminal of the second shift register IC2 is connected to the LED0, LED1, LED2, and LED3 of the LED indicator circuit. DGT0 to DGT3 are driven by transistors Q1 to Q4, respectively. The display refresh data generated by the display refresh segment is output through the first shift register IC1 and the second shift register IC2, which respectively drive the digital tube display circuit and the LED indicator circuit. The LED indicator circuit is mainly used to display the running status, key feedback status, fault alarm status and over-limit alarm status. During use, the display control module can adopt a display method combining LCD display and LED status indicator lights.

[0034] The sensor interface module includes an IIC sensor interface, an SPI sensor interface, and a UART sensor interface. Sensors with different communication protocols are connected to the microcontroller module through the corresponding sensor interface module.

The DIP switch controls whether the matching resistor is connected to the communication line to adapt to different communication distances and networking environments. The wireless communication module can connect to a SIM card interface and an external antenna, and can also be replaced with a LoRa communication module as needed. The WIFI module can interact with the MQTT cloud platform, enabling sensor data, alarm status data, and fault status data in the runtime data structure to be uploaded to the cloud platform and to receive remote configuration parameters.

[0036] The analog output module includes a DAC module, a conditioning amplifier circuit, and a voltage-to-current conversion module. The analog output data generated by the analog output refresh segment is converted into a voltage signal by the DAC module. This voltage signal is then processed by the conditioning amplifier circuit and enters the voltage-to-current conversion module, which outputs a 4-20mA current transmission signal. The conditioning amplifier circuit can be equipped with an adjustable potentiometer to adjust the output voltage range. The analog output module can provide a 0-3.3V or 0-5V voltage output terminal via an analog interface as needed, facilitating on-site debugging or observation via an oscilloscope.

Configuration parameters include sensor configuration parameters, communication configuration parameters, alarm thresholds, display configuration parameters, and linkage configuration parameters. The configuration parameters generated or received by the parameter setting module are written to the storage module.

[0038] The storage module includes an EEPROM, which is connected to the microcontroller module. The EEPROM stores sensor configuration parameters, communication configuration parameters, alarm thresholds, display configuration parameters, and linkage configuration parameters.

Alarm thresholds may include the upper and lower limits of sensor alarms. Display configuration parameters may include display channels, display refresh mode, and screen scrolling mode. Linkage configuration parameters may include the correspondence between alarm events and relay output circuits and optocoupler output circuits. Storing these configuration parameters in the EEPROM reduces frequent writes to the microcontroller module's internal storage.

[0039] The present invention also includes a power supply module, which is connected to the microcontroller module, sensor interface module, communication output module, analog output module, linkage control module, and display control module. The power supply module includes a first power interface, a second power interface, a rectifier-step-down module, a step-down module, a charging control circuit, a backup battery, and a voltage detection circuit.
