Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figures 1 to 3 , the utility model provides a technical solution:

[0026] A reset signal detection communication system, comprising:

[0027] The microcontroller 10 is electrically connected to the signal detection module 20 and is used to process the analog signal collected by the signal detection module 20; the model of the microcontroller 10 is an STM32F4 single-chip microcomputer, with a built-in A / D converter and a D / A converter, which are respectively used to convert analog signals into digital signals and convert digital signals into analog signals. The signal detection module 20 is electrically connected to the power supply module 30 and is used to collect analog signals of temperature, humidity, and flow rate; the microcontroller 10 can compare and process the data. After setting the threshold, the microcontroller 10 can convert the collected analog signal into a digital signal and compare it with the threshold. When the detected data value is a null value within a certain period of time, it indicates that the signal detection module 20 has a fault. The microcontroller 10 sends a control signal to control the transistor switch 40 to open and close. The transistor switch 40 controls the temperature sensor 21, the humidity sensor 22, and the flow sensor 23 to disconnect and restart, thereby resetting the signal detection module 20, automatically eliminating certain faults, and saving manpower.

[0028] Temperature sensor 21, humidity sensor 22, and flow sensor 23 are all semiconductor sensors with high sensitivity and accuracy. The relevant values ​​collected by temperature sensor 21, humidity sensor 22, and flow sensor 23 are transmitted to a terminal receiving device via microcontroller 10 and communication module 50. The terminal receiving device is equipped with a CMS management system and an HMI human-computer interface window, respectively used for data classification and management and to assist in manual review of relevant data.

[0029] In order to ensure the normal operation of the present invention, the microcontroller 10, the communication module 50, and the alarm module 70 are powered by another set of power supplies.

[0030] The power module 30 is electrically connected to the transistor switch 40 and is used to supply power to the signal detection module 20. The power module 30 uses a battery. The power module 30, the transistor switch 40, and the signal detection module 20 are connected in series. When the transistor switch 40 is turned on and off, the signal detection module 20 is reset.

[0031] The transistor switch 40 is electrically connected to the microcontroller 10 and is used to control the reset and restart of the signal detection module 20. The model of the transistor switch 40 is TIP111. The microcontroller 10 controls the base current by controlling the current between the collector and emitter of the transistor switch 40 through the control signal. When the base current is large enough, the transistor enters a saturation state, which is equivalent to a closed switch. When the base current is zero, the transistor is cut off, which is equivalent to an open switch, achieving reset and high stability.

[0032] The communication module 50 is electrically connected to the microcontroller 10 and is used to send wireless signals to a terminal receiving device.

[0033] Furthermore, the signal detection module 20 includes a temperature sensor 21, a humidity sensor 22, and a flow sensor 23 connected in parallel, which are used to detect temperature analog signals, humidity analog signals, and flow rate analog signals, respectively. The temperature sensor 21 uses a WZPT-035 temperature sensor to monitor the ambient temperature and send an analog signal to the microcontroller 10. The humidity sensor 22 is AHT20DFN6, and the flow sensor 23 is S201B.

[0034] Furthermore, the communication module adopts an RS485 wireless communication module for transmitting wireless signals to a terminal receiving device. The RS485 wireless communication module can wirelessly transmit the digital signal data processed by the microprocessor 10 to a portable terminal receiving device of a nearby staff member, thereby facilitating the staff member to view monitoring data and alarm information.

[0035] Furthermore, it also includes an alarm module 70, which is electrically connected to the microcontroller 10 and is used to alarm the staff. The alarm module 70 includes a buzzer 71 and an LED alarm light 72 connected in series, which are used to alert the staff through sound and light respectively. When the temperature data, humidity data, and flow rate data exceed the threshold, the alarm module 70 works and emits an audible and visual alarm to alert the staff that an abnormality has occurred in the area to be detected.

[0036] Furthermore, the system further includes an SD storage module 60 for storing digital signals processed by the microcontroller, and can store temperature data, humidity data, and flow rate data.

[0037] The working principle of the present invention is as follows: the microcontroller 10 converts analog signals into digital signals and converts digital signals into analog signals, and the signal detection module 20 collects analog signals of temperature, humidity and flow rate; the microcontroller 10 can compare and process the data. After setting the threshold, the microcontroller 10 can convert the collected analog signals into digital signals and compare them with the threshold. When the detected data value is null within a certain period of time, it indicates that the signal detection module 20 has a fault. The microcontroller 10 sends a control signal to control the transistor switch 40 to open and close. The transistor switch 40 controls the temperature sensor 21, the humidity sensor 22 and the flow sensor 23 to disconnect and restart, thereby resetting the signal detection module 20, automatically eliminating certain faults and saving manpower.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
