[0002] With the development of smart grid technology, the monitoring requirements for circuit breakers are constantly increasing. Temperature sensors are a key component of circuit breakers. Existing temperature sensors typically rely on current transformers for induction power to start, resulting in weak current stability. Furthermore, they often require additional communication modules to transmit data with the host, leading to a large starting current demand and high energy consumption during continuous operation.

The voltage regulator unit 22 provides a stable DC voltage to the control module 1, the temperature sensor T1, and the wireless communication module 4. The voltage regulator unit 22 is connected to the DC input terminal DC_IN, the wireless communication module 4, the energy storage unit 21, the monitoring module 3, the temperature sensor T1, and the control module 1. The energy storage unit 21 is connected in parallel with the monitoring module 3, which monitors the voltage across the energy storage unit 21. The control module 1 is connected to the monitoring module 3 and controls the temperature data transmission and the operation of the wireless communication module 4 based on the monitored voltage. The energy storage unit 21 provides short-term high-current support for the data transmission of the temperature sensor T1, ensuring normal system operation. The temperature sensor T1 and the wireless communication module 4 have working and sleep states, eliminating the need for continuous operation, reducing current demand, operating time, and energy consumption, thereby improving system stability and safety.

[0041] In a specific embodiment, the energy storage unit 21 includes an energy storage capacitor CT1, which is connected in parallel with a first resistor R1 and a second resistor R2 connected in series. One end of the energy storage capacitor CT1 is connected to a temperature sensor T1, and the other end is connected to a control module 1. The temperature sensor T1 is connected to the control module 1, and the connection point of the first resistor R1 and the second resistor R2 is connected to the control module 1, so as to realize real-time and accurate monitoring of the input voltage. The control module 1 can obtain voltage information in a timely manner to provide a basis for subsequent module control.

[0042] Figure 5 A circuit diagram of a temperature sensor system according to Embodiment 5 of this application is shown, as follows: Figure 5 As shown, optionally, the control module 1 is an MCU (Microcontroller Unit), the voltage regulation unit 22 includes an LDO (Low Dropout Regulator), and the monitoring module 3 includes a first resistor R1 and a second resistor R2 connected in series. The input terminal of the first resistor R1 is connected to the energy storage unit 21, and the connection point of the first resistor R1 and the second resistor R2 is connected to the AD pin of the MCU.

[0043] In a specific embodiment, the control module 1 includes an integrated analog-to-digital converter (ADC) unit and a judgment unit. The ADC pin acquires the voltage monitored by the monitoring module 3 in real time. The ADC pin is electrically connected to the ADC unit, which converts the voltage into digital voltage data. The judgment unit is electrically connected to the ADC unit and determines whether the digital voltage data meets a transmission voltage threshold. The control module 1 controls temperature data transmission based on the threshold condition, achieving precise voltage monitoring and maximizing energy efficiency. Furthermore, by determining whether the digital voltage data meets the transmission voltage threshold, it controls the wireless communication function, further enhancing low-power design and reliability.

[0044] In a specific embodiment, the wireless communication module 4 is provided with a data transmission port and a data input port, and the control module 1 includes a differential signal unit. The differential signal unit is provided with a positive transmission port TP1+ and a negative transmission port TP1-. The positive transmission port TP1+ is communicatively connected to the data input port DI, and the data transmission port DS is communicatively connected to the negative transmission port TP1-. The control module 1 receives a wake-up signal and temperature data to be transmitted from the control module 1 through the data input port DI, and sends an acknowledgment signal from the host to the control module 1 through the data transmission port DS.

[0045] In a specific embodiment, the temperature sensor T1 is equipped with a control transceiver unit for receiving an enable signal from the control module 1 and transmitting temperature data. The control module 1 is also equipped with a temperature transceiver unit for transmitting the enable signal and receiving the temperature data. Optionally, the transmission of the enable signal and the reception of temperature data can be achieved by connecting a data line through a GPIO port in the MCU. The temperature transceiver unit is communicatively connected to the control transceiver unit. This enables the control module 1 to control the data transmission of the temperature sensor T1, avoiding continuous operation and reducing the overall system energy consumption.

[0046] In a specific embodiment, the wireless communication module 4 is further provided with a wireless communication interface for wireless communication connection with the host. Through this interface, the module sends the temperature data to be transmitted to the host based on the wake-up signal, and receives a response signal, frequency band, and preset period from the host. This ensures communication stability when multiple temperature sensors are present, avoids signal interference, and improves data transmission reliability. Receiving the frequency band from the host ensures that the temperature sensor system and the host operate according to the corresponding frequency band. It should be noted that the response signal refers to the feedback signal sent by the host to the wireless communication module, and the preset period refers to the data field containing period information sent by the host to the wireless communication module.

[0047] In a specific embodiment, the control module 1 also integrates an anomaly handling unit, used to restart the control module 1 when the wireless communication module 4 receives an abnormal response signal or the temperature sensor T1 transmits data abnormally. This reduces maintenance costs and improves the stability and security of the temperature sensor system.

[0048] In specific embodiments, the temperature sensor system of this application can be applied to a circuit breaker. The circuit breaker is equipped with the temperature sensor system described in any of the above embodiments. Optionally, the circuit breaker is a vacuum circuit breaker. The application of the above-described temperature sensor system to a circuit breaker can maintain stable operation of the circuit breaker, reduce energy consumption, extend service life, and reduce operating costs.

[0049] The following is combined Figure 5The specific coordination of each module and unit in the temperature sensor system of this application is described as follows: The temperature sensor T1 is equipped with a control transceiver unit for receiving enable signals from the MCU. When temperature data transmission is required, the MCU wakes up the temperature sensor T1 to transmit the data and sends the temperature data to the MCU. At the same time, the voltage across the energy storage capacitor CT1 monitored by the monitoring module 3 is collected in real time through the AD pin of the MCU. The judgment unit in the MCU judges whether the digital voltage data converted by the analog-to-digital converter meets the transmission voltage threshold, that is, whether the voltage across the energy storage capacitor CT1 is greater than the communication working voltage, that is, whether the energy storage capacitor CT1 can provide enough voltage to maintain the operation of the wireless communication module 4 once. If it meets the threshold, a data transmission operation is performed. If it does not meet the threshold, the system continues to wait for the energy storage capacitor CT1 to charge.

[0050] Specifically, the MCU sends a wake-up signal and the temperature data to be transmitted to the data input port DI of the wireless communication module 4. The wireless communication module 4 then begins transmitting data, sending the temperature data to the host via its wireless communication interface. If the voltage across the energy storage capacitor CT1 is lower than the minimum operating voltage after transmission, the wireless communication module 4 cannot continue operating and enters a sleep state. After one transmission, if the voltage across the energy storage capacitor CT1 is greater than the minimum operating voltage, the wireless communication module 4 continues to operate, and its wireless communication port waits for a response signal from the host. Continuous operation refers to the state where the wireless communication module 4 waits for a response signal from the host after transmitting data. By controlling the operation of the wireless communication module 4 through voltage monitoring, the power consumption and startup current of the temperature sensor system are reduced.

[0051] Specifically, after the wireless communication interface of the wireless communication module 4 receives the response information from the host, the data transmission port DS of the wireless communication module 4 sends the response information to the MCU. This allows the anomaly handling unit to immediately detect any response anomalies in the wireless communication module 4. Specifically, if the wireless communication module 4 fails to receive response information multiple times consecutively, or if the temperature sensor T1 fails to transmit data multiple times consecutively, the MCU watchdog timer is triggered to reset. If an anomaly is detected, the MCU restarts. By implementing the anomaly handling unit, timely adjustments are made when system anomalies occur, ensuring stable system operation.

[0052] Specifically, the wireless communication module 4 receives preset cycles from the host and transmits them to the MCU. The MCU controls the temperature sensor T1 and the wireless communication module 4 to send data according to the received preset cycles, thus avoiding communication conflicts between multiple transmitters during wireless communication.

[0053] In a specific embodiment, the output terminal of the voltage regulator unit 22 is connected to the power supply terminals of the control module 1 and the wireless communication module 4. The connection point of the first resistor R1 and the second resistor R2 is connected to the AD pin of the MCU, namely the analog-to-digital conversion pin ADC_VMON. A bidirectional trigger diode D1 and a capacitor C1 are connected between the LDO and the wireless communication module 4. The capacitor C1 is connected in parallel with the bidirectional trigger diode D1.

[0054] In a specific embodiment, one end of the energy storage capacitor CT1 is connected to the DC input terminal DC_IN, the LDO, the first resistor R1, and the temperature sensor T1. The other end of the energy storage capacitor CT1 is connected to the second resistor and the MCU. One end of the temperature sensor T1 is connected to the TR Sensor port of the MCU. In this specific embodiment, the voltage input to the DC input terminal DC_IN is regulated by the voltage regulator unit 22 and outputs a 3.3V voltage. The resistance of the first resistor R1 is 10kΩ, and the resistance of the second resistor R2 is 20kΩ.

[0055] In a specific embodiment, a transistor Q1 and a resistor R4 are also connected between the wireless communication module 4 and the MCU. The emitter of the transistor Q1 is connected to the enable terminal EN of the wireless communication module 4, and a resistor R5 is provided between the collector and base of the transistor Q1. Preferably, the transistor Q1 is an NPN transistor.

The protection circuit is also connected to the output terminal VO of the LDO and the bidirectional trigger diode D1.

[0057] In a specific embodiment, the SIP2 port of the wireless communication module 4 is grounded through resistor R6 and capacitor C3.

[0058] In a specific embodiment, the temperature sensor T1 is a DS18B20, the MCU is an STM32F103, and the wireless communication module 4 is a CC1101.

[0059] Figure 6 A circuit diagram of a temperature sensor system according to Embodiment 6 of this application is shown, as follows: Figure 6As shown, it also includes a current transformer 6 and a rectifier module 5. The power supply for the DC input terminal DC_IN is generated by the current transformer 6 and the rectifier module 5. The current transformer 6 generates current. Since the current generated by the current transformer 6 is unstable, the AC power is rectified by the rectifier module 5 to obtain DC power, and then the DC power is input to the power supply module 2 to power the subsequent temperature sensor T1, control module 1, and wireless communication module 4. The energy storage unit 21 is used to ensure the normal operation and data transmission and reception of the temperature sensor T1, avoiding the influence of the unstable output current of the current transformer 6. Optionally, the rectifier module 5 includes a rectifier bridge.

[0060] It should be noted that the host in this application refers to a device that interacts with the temperature sensor system to perform data exchange, implement upper-level control, or perform data processing. It can be an embedded host, a microcontroller main control board, a server, a cloud server, or a human-computer interaction host, etc.

[0061] It should be noted that the wake-up signal refers to the enable signal that starts the wireless communication module 4. The enable signal is a level signal used by the control module to control the corresponding module to work or go into sleep mode. In essence, it realizes the switching management of the power supply or data path of the target module through the logic control of the hardware circuit. The module works when the enable signal is received, and the module goes into sleep mode when the enable signal is not received.

[0062] It should be noted that the temperature transceiver unit can be integrated into the MCU or it can be an external port of the MCU; the control transceiver unit can be integrated into the temperature sensor T1 or it can be an external port of the temperature sensor T1.
