Description
Technical Field
The utility model relates to a wireless power supply's temperature measuring device, wireless temperature measurement technical field.
Background
The current electric equipment/contact temperature measuring device can not be supplied with power through an external power supply in a wired mode due to the fact that high voltage exists when a temperature measuring point works. In general, wireless temperature measurement systems in the market adopt battery power supply, current induction power supply, voltage induction power supply and other modes. Wherein:
firstly, battery power supply: the temperature measuring point of the electrical equipment/contact can reach 50-60 ℃ or even more than 125 ℃ in normal work, the failure rate of the battery is increased sharply under the high-temperature condition, and the power supply reliability is reduced; the battery is used for supplying power, so that energy is saved, temperature data cannot be sent at any time, the temperature data is often sent once at a long time interval, and the temperature of a measuring point cannot be reflected in time; when the electric quantity of the battery is exhausted, the work of the tested electric system must be stopped by replacing the battery, which wastes time and labor.
II, current induction power taking: the current induction electricity is supplied with power through a magnetic field generated by current around a conductor, a current induction magnetic material and a coil are installed near a temperature measuring point, and electric energy is generated through current flowing through the conductor of the induction temperature measuring point. However, current does not necessarily flow near some temperature measuring points, and the current induction power-taking working scene is limited; when the working current is small, the induced electric energy is small, the requirement of the wireless temperature measuring device cannot be met, and the minimum working current is strictly limited by the wireless temperature measuring device adopting the current induction mode to obtain electricity.
Thirdly, taking electricity in a voltage induction mode: the voltage induction mode obtains electric energy through an electric field around the high-voltage conductor, the obtained electric energy is not influenced by loads, and the electric energy can be obtained as long as the device to be detected is electrified. However, in the voltage induction power-taking mode, the obtained electric energy is very small, and the temperature measurement and the wireless communication can be completed only once by continuously accumulating electric charges. The temperature measuring device adopting voltage induction to obtain electricity usually needs charging for more than 10 minutes when being electrified, and after being fully charged, the data transmission frequency can be generally realized only once in 3 minutes, and the rapid change of the temperature of a measured point cannot be reflected in real time.
