Detailed Description
The technical solution of the present invention will be described in further detail with reference to the following specific embodiments and accompanying drawings, but the scope of protection and the implementation of the present invention are not limited thereto.
As shown in the attached drawing 1 of the specification, the alarm device of the false alarm prevention type temperature control system comprises a temperature sensing module used for measuring the temperature of an electric element, wherein the temperature sensing module is electrically connected with the input end of a measuring instrument and comprises a plurality of temperature sensors, the number of the temperature sensors is greater than 2, the output end of the measuring instrument is further connected with an operation module, and the control end of the operation module is connected with an alarm prompt module.
The temperature sensing module measures the temperature of the measured transformer, the measured temperature signal is output to the measuring instrument, the measuring instrument outputs a temperature value to the operation module for processing operation after processing, whether the measured temperature is higher than 110 ℃ is judged, and if the measured temperature is higher than 110 ℃, a low potential signal is output to the alarm prompting module for alarm processing.
The number of the temperature sensors is 8.
The 8 temperature sensors effectively avoid the false alarm condition of the alarm device of the temperature control system, and alarm processing is carried out when the temperature measured by more than three temperature sensors exceeds 110 ℃.
As shown in the attached figures 1 and 2 in the specification, the signal output end of the temperature sensor is connected with the signal input end of the temperature instrument through an optical coupler U9.
The optocoupler U9 processes the voltage signal collected by the temperature sensor, so that the input voltage of the measuring instrument is not too high, and an isolation protection effect is achieved.
As shown in fig. 1 and 3 of the specification, the alarm prompt module includes a triode Q1, a light emitting diode LED1 and a buzzer, the base of the triode Q1 is used as the controlled end of the alarm prompt module to be connected with the control end of the operation module, the collector of the triode Q1 is connected with a voltage source VCC through a resistor R2, the collector of the triode Q1 is further connected with the light emitting diode LED1 and the buzzer which are connected in parallel, and the cathodes of the light emitting diode LED1 and the buzzer are grounded.
