Abstract
The utility model relates to a constant-temperature monitoring bluetooth warner which comprises a heating module, a heat sensing module, a heating circuit control module and a bluetooth warning module. The constant-temperature monitoring bluetooth warner is characterized in that the heating module, the heat sensing module, the heating circuit control module and the bluetooth warning module are sequentially connected; the heat sensing module monitors the temperature of the heating module through a thermal resistor; when the temperature is higher than a user-defined temperature, the heating circuit control module disconnects a heating circuit; when the temperature gradually decreases, the heating circuit control module reconnects the heating circuit, thereby achieving the purpose of controlling the temperature; and if the temperature is lower or higher than the defined temperature for a long time, a warning message can be sent out through the bluetooth warning module.
Description
Technical field
The utility model relates to a kind of thermo-monitor that adds, especially constant temperature monitoring bluetooth alarm.
Background technology
Well heater is the equipment of often using at various production fields, and the time of traditional well heater insulation is not long.Some well heaters are also arranged now, come heat supply through the water in the heating water heating device, but this mode is dangerous on the one hand; After temperature is too high; Cause hot water to flow out easily and hurt sb.'s feelings, and remote alarm function can not be provided, in time handling failure; Some thermostat that has a radio alarming function is the special-purpose wireless transmitter of needs then, can not be directly with notebook on blue-tooth device communicate by letter and be connected.
Summary of the invention
Need the often more inconvenience of heat exchange water in order to overcome conventional heater, and the heter temperature of electric heating dangerous after too high, breaking down can only local alarm; The problem that the wireless alarm devices specificity is too strong, the utility model provide a kind of constant temperature monitoring bluetooth alarm, not only do not need more heat exchange water; And heating-up temperature is adjustable; Can not cause potential safety hazard, breaking down can remote alarm, in time notifies the monitor staff to handle.The utility model is easy to use, safe, and is with low cost.
The utility model solves the technical scheme that its technical matters adopted: constant temperature monitoring bluetooth alarm comprises heating module, hot sensing module, heater circuit control module, bluetooth alarm module, and it is characterized in that: heating module, hot sensing module, heater circuit control module, bluetooth alarm module connect successively.Hot sensing module is through the temperature of thermistor monitoring heating module; Temperature is higher than after user's setting; Break off heater circuit through the heater circuit control module, after temperature reduced gradually, the heater circuit control module connected heater circuit again; Reach temperature controlled purpose, if be lower than for a long time or be higher than design temperature then send warning through the bluetooth alarm module.
The beneficial effect of the utility model is, need not change heatable substance, and heating-up temperature is adjustable, but the fault remote alarms, and notebook bluetooth equipment that can be direct with general is connected.
Description of drawings
Fig. 1 is the theory diagram of the utility model; Fig. 2 is the electric structural drawing of the utility model.
Embodiment
In Fig. 1; Constant temperature monitoring bluetooth alarm comprises heating module 1, hot sensing module 2, heater circuit control module 3, bluetooth alarm module 4, and it is characterized in that: heating module 1, hot sensing module 2, heater circuit control module 3, bluetooth alarm module 4 connect successively.The heating material of heating module 1 adopts electric furnace heating wire, and insulation material adopts asbestos cloth.Hot sensing module 2 is through the temperature of thermistor monitoring heating module 1; Regulate temperature through potentiometer, temperature is higher than after user's setting, breaks off heater circuits through heater circuit control module 3; After temperature reduces gradually; Heater circuit control module 3 connects heater circuit again, reaches temperature controlled purpose, if be lower than for a long time or be higher than design temperature then send warning through bluetooth alarm module 4.
In Fig. 2, dual operational amplifier LM358 is connected into window comparator, and after switch QS1 closure, voltage is about 6V, is higher than pin No. 5, is lower than pin No. 2.No. 2 pin of amplifier A1 are higher than pin, A1 output low level No. 3.No. 6 pin of amplifier A2 are higher than pin, A2 output low level No. 5.Triode, VT1 end,, the VT2 saturation conduction, contactor J1 gets electric adhesive, pilot lamp VD1 lights, heating Bao Dedian heating.Along with the rising of temperature, the resistance of thermistor reduces in the heating bag, and A point current potential descends.When A point current potential was lower than No. 5 pin, A2 exported high level, the VT1 saturation conduction, and VT2 ends, and the J1 dead electricity is broken off, and VD1 extinguishes.Along with the continuity of time, the RT temperature descends, and resistance rises, and A point current potential rises, when A point current potential is higher than No. 5 pin, and the A2 output low level.Contactor J1 gets electric adhesive.So just can keep a steady temperature.Regulator potentiometer RW can obtain different constant temperature values.In use, no matter RT is that RT damage, open circuit or short circuit can both make A point current potential drop on outside the window voltage of LM358 as thermal sensor; No. 1 pin or No. 7 pin of being LM358 always have an output high level that J1 is broken off; Can not cause heating bag overheated, reaching the purpose of safe handling, if be lower than for a long time or be higher than design temperature then point out long-range supervisory user to have the failure safe problem through the mode of bluetooth; Pass through bluetooth approach; Send the interlock signal in blue tooth radio network, ROK 101 008 serial bluetooth modules are deferred to bluetooth 1.1 standards, are the communication modules of a point-to-multipoint.This module can be simultaneously and in its scope connected 7 bluetooth slave units realize data transmission.The effective radius of Bluetooth communication is relevant with the power of its output, can suitably improve emissive power when needing to strengthen communication distance.
