Embodiment 1

[0030] A heating and self-feeding temperature fusion sensor, such as figure 1 As shown, it includes: power supply module, PTCR management circuit, PTCR, and main control module. Among them, the PTCR management circuit is used to switch the working state of the PTCR and collect current information. The PTCR management circuit is also used to protect the PTCR from overcurrent. When the PTCR is in the working state, the power supply module sends the PTCR a Power supply, while ensuring the normal heating of PTCR, when the PTCR overcurrent occurs, the overcurrent protection mechanism of the PTCR management circuit ensures the safety of the PTCR; the main control module is used to analyze the current information collected by the PTCR management circuit to obtain the PTCR temperature.

[0031] The main control module can be called the main control layer. The power supply module and the PTCR management circuit can be called the action layer as a whole. The action layer is used to real...

Embodiment 2

[0047] An application of a heating and self-feeding temperature fusion sensor as described above is applied to the measurement of flow field information, specifically: the sensor is placed in the flow field to be measured, and the current information collected by the sensor is analyzed to obtain flow field information.

[0048] The PTCR management circuit can realize that the PTCR can pass the sensed physical quantity to the main control module for signal processing and conversion under normal conditions, and obtain the physical quantity information of the flow field.

[0049] For example, if Figure 7 As shown, a PTCR-based heating and self-feeding temperature fusion sensor is provided, which includes armor, PTCR element, PTCR holder and main control circuit. The armor is used to protect the PTCR element and conduct heat, and the PTCR element is used For heating and measurement, the main control circuit is mainly used for signal processing.

[0050] Through this solution, a...

Abstract

The invention belongs to the field of temperature sensors, and specifically relates to a heating and self-feeding temperature fusion sensor and its application, including: a power supply module, a PTCR management circuit, a PTCR, and a main control module; the PTCR management circuit is used to control the working state of the PTCR The switching of the PTCR and the collection of current information, among them, the PTCR management circuit is also used to protect the PTCR from over-current. When the PTCR is in the working state, the power supply module supplies power to the PTCR through the PTCR management circuit. While ensuring the normal heating of the PTCR, it acts as a PTCR When an overcurrent occurs, the safety of the PTCR is guaranteed through the overcurrent protection mechanism of the PTCR management circuit; the main control module is used to analyze the current information collected by the PTCR management circuit to obtain the PTCR temperature. The invention provides a heating and self-feeding integrated device, which not only has a high ability to convert electric energy into heat energy, but also can easily reflect its own temperature, so as to achieve the purpose of integrating the actuator and the sensor , which can be applied to measure flow field information.

Description

technical field [0001] The invention belongs to the field of temperature sensors, and more specifically relates to a heating and self-feeding temperature fusion sensor and its application. Background technique [0002] Since the 1960s, PTCR components for various purposes have emerged continuously, and they can be found in household appliances, industrial electronic equipment and other fields. In the article "Application of PTC electric heating on air conditioners" published in "Architectural Engineering Technology and Design", the PTC electric heater is applied to the air conditioner. In the harsh winter environment, PTC is used as an electric auxiliary heating device to ensure The air conditioner is able to provide normal heating capacity. In the article "Control Scheme Design of PTC Heater for Electric Air Conditioner" published in "Beijing Automobile", the air conditioner PTC heater for pure electric vehicles is designed, which reduces the energy consumption of the whol...
