The subject matter herein generally relates to temperature monitoring systems and temperature monitoring methods using the same.
It is necessary to measure the temperature of the environment parameter for each workshop. Usually, the temperature is measured manually with temperature sensing elements.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references can mean “at least one.”
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasable connected. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
The present disclosure is described in relation to a temperature monitoring system. The temperature monitoring system includes a detection module, a control module with a predetermined temperature value, and a display module. The detection module is configured to detect and generate an actual temperature value. The control module is configured to compare the actual temperature with the predetermined temperature value. The display module is coupled to the detection module via the control module, and is configured to display the actual temperature value. When the control module identifies the actual temperature value is greater than the predetermined temperature value, the display module is controlled by the control module to display an alert indicator. The present disclosure further discloses a temperature monitoring method.
In at least one embodiment, the control module 20 includes a chip U1, the detection module 10 includes a chip U1, and the display module 30 includes display equipment (not shown). The chip U1 is a STC89C52single chip micro controller, and the chip U1 is a DS18B20 chip.
The control module 20 includes a time-delay circuit 21 and an oscillating circuit 22. The time-delay circuit 21 is configured for time delaying and resetting, and the oscillating circuit 22 is configured for controlling an instruction cycle of the control module 20. The time-delay circuit 21 is coupled to a pin RST of the chip U1. The oscillating circuit 22 is coupled to a pin XTAL1 and a pin XTAL2 of the chip U1. In at least one embodiment, the time-delay circuit 21 is a RC time-delaying circuit. In another embodiment, the oscillating circuit 22 includes a crystal oscillator Y1. A pin P2.2 of the chip U1 is coupled to the pin DQ of the chip U2 for receiving the actual temperature value.
The alarm module 40 includes a switch Q1 coupled to a pin P2.0 of the chip U1 and a buzzer U3 coupled to the switch Q1. The control signal is transmitted from the control module 20 to the switch Q1 via the pin P2.0. The switch Q1 is switched on/off by the control signal. The buzzer U3 for sounding alarm is turned on/off by the switch. Thereby, the buzzer U3 is controlled by the control signal to buzz.
In at least one embodiment, the switch Q1 is a PNP type transistor. A base of the transistor is coupled to the control module 20, an emitter of the transistor is coupled to the buzzer U3, and a collector of the transistor is grounded.
In at least one embodiment, the buzzer U3 can be replaced by a bell or other sound equipment.
In at least one embodiment, a limiting resistor R11 is coupled between the control module 20 and the switch R11, to limit the electric current from the control module 20 to the alarm module 40.
In at least one embodiment, each pin P0.0-P0.7 of the chip U1 is coupled to each of the pull-up resistors R1-R8.
Referring to
At block 401: the detection module 10 detects environment temperature and generates an actual temperature value.
At block 402: the display module 30 displays the time and the corresponding actual temperature value synchronously.
At block 403: the control module 20 compares the actual temperature value with the predetermined temperature value; if the actual temperature value is greater than the predetermined temperature value, go to block 404 and block 405, and if the actual temperature value is less than or equal to the predetermined temperature value, go to block 406.
At block 404: the control module 20 transmits the alarm signal to control the display module 30 to display the alert indicator.
At block 405: the control module 20 transmits the control signal to control the alarm module 40 to sound alarm.
At block 406: the control module 20 transmits the normal signal to control the display module 30 to display the normal indicator.
Block 402 and block 403 are executed synchronously, and block 404 and block 405 are executed synchronously.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
