The remote GSM temperature alarm device has the advantages that a rechargeable lithium battery is arranged in the device, so that the remote GSM temperature alarm device can work for a long time in a place without an external power supply; and the remote GSM temperature alarm device has the characteristics of convenience in operation, flexibility, attractive appearance, limitless transmission distance, low data transmission cost and the like.
Description
Technical field
The utility model relates to the monitoring temperature technical field; It specifically is a kind of long-range GSM temperature alarm; Be widely used in the storage and the transportation of food, medicine and fresh and alive article and the industry that meets the HACCP system certification, also can be used for the place that laboratory etc. needs temperature is done monitoring.
Background technology
In modern society; Implementation along with the HACCP authentication; Monitoring temperature requirements at the higher level have been proposed; In industry and fields such as freezing and refrigeration, health care, greenhouse management, aquatic animal cultivating, food accumulating, historical relic preservation, building materials experiment, health cares, we no longer are satisfied with and must just can know the alarm that temperature conditions and hummer or audible-visual annunciator provide to on-the-spot, and the demand in market has caused the remote temperature alarm.The producer that produces Short message alarm at present is more; Because of the GSM alarm of a lot of manufacturer production mostly is only to have that the switching value warning function promptly needs and temperature controller uses together and could realize SMS alarm function and basically all adopt English note to control alarm; Complicated operation; Can not obtain popularizing and using in the cold chain industry,, use to have certain limitation at the special occasions of some no power supplies.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of GSM remote temperature alarm, and is easy to operate, need not connect temperature controller and can realize SMS alarm through the gsm wireless communication.
The utility model is realized with following technical scheme: a kind of long-range GSM temperature alarm; Comprise a single-chip microcomputer; Be connected the temperature sensor that is used for the collecting temperature data with single-chip microcomputer, be connected the button that is used to be provided with parameter or inquiry temperature value with single-chip microcomputer, be connected the display device that is used for displays temperature with single-chip microcomputer; The power module that is connected with single-chip microcomputer, the warning device that is connected with single-chip microcomputer; Single-chip microcomputer connection one is used for the SMS module of gsm wireless communication.
Principle of work: temperature sensor is delivered to single-chip microcomputer with the temperature data that collects, and the upper and lower limit alarm temperature is set in advance, and in the scope of setting, temperature is showing on display device as if temperature; Send information through SMS module to the mobile phone of appointment simultaneously if temperature, starts warning device not in range of set temperature, the temperature that collects shows in display device.In addition, this instrument can be with the temperature value timed sending to user mobile phone.
The beneficial effect of the utility model: having broken in the past needs to use the history that could realize SMS alarm together with temperature controller, and low-power consumption has guaranteed ability long-term work under the situation of no external power source; Can carry out relevant parameter to this alarm through the input mode of Chinese user friendly operation is set; Have timed sending function, with the temperature value timed sending to user mobile phone; Support arrearage prompting prevents that SIM can not SMS alarm because of no expense.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the theory diagram of the utility model;
Fig. 2 is the program main flow chart of the utility model.
Embodiment
As shown in Figure 1; Long-range GSM temperature alarm has a single-chip microcomputer; Be connected the temperature sensor that is used for the collecting temperature data with single-chip microcomputer, be connected the button that is used to be provided with parameter or inquiry temperature value with single-chip microcomputer, be connected the display device that is used to show various states with single-chip microcomputer; The power module that is connected with single-chip microcomputer, the warning device that is connected with single-chip microcomputer; Be connected the SMS module that is used for the gsm wireless communication with single-chip microcomputer.
In the present embodiment, sensor assembly adopts two NTC RTDs and double switch amount load module, and two NTC RTDs are connected with single-chip microcomputer respectively with double switch amount load module.
Warning device comprises a relay and hummer, and hummer is connected with single-chip microcomputer through relay.
Display device adopts LCD display, but LCD display can be indicated each duty query history record maximal value, minimum value.
Through button alarm temperature is set, can regularly pushes information such as temperature value and power supply state, also can inquire about temperature value and power supply state in real time, meet the requirement of HACCP to user mobile phone.
SMS module is supported the arrearage prompting, prevents SIM warning of can not sending short messages because of Sorry, your ticket has not enough value; Adopt the Chinese short message input mode, greatly facilitate the user's actions.Also can check power supply state, can know accurately whether current freezer is in power down mode through the mode of SMS.
Each module adopts the low-power consumption components and parts of high-performance high integration, adopts rational power management, has guaranteed the low-power consumption of product.Power module adopts chargeable lithium cell, can work long hours in the occasion of no externally fed, has characteristics such as easy to operate, flexible, that outward appearance is generous, transmission range unrestricted (as long as the network coverage is arranged), data transmission are with low cost.
The mcu programming language is the C language, the IAR translation and compiling environment.Software section adopts the message data format of transfering based on hexadecimal code, can realize the time-division processing of short message, thereby solves the time-delay of GSM short message and the problem of unreliable transmission, avoids note and sends the influence of peak period to message pick-up.
As shown in Figure 2, under the normal display working condition of system: button gets into the system parameter setting state,
Concrete operation method is following:
The 1 tunnel temperature relevant parameter is provided with; Button is to MODE 1 demonstration, and " 1 " flicker, and button confirms to get into this setting option again; Show respectively upper temperature limit, upper limit radix point, lowest temperature, lower limit radix point are set; Return difference value (return difference value will between upper and lower bound) after new argument is provided with completion, is preserved amended parameter by the SET key.
The 2 tunnel temperature relevant parameter is provided with; Button is to MODE 2 demonstrations, and " 2 " flicker, and button confirms to get into this setting option again; Show respectively upper temperature limit, upper limit radix point, lowest temperature, lower limit radix point are set; Return difference value (return difference value will between upper and lower bound) after new argument is provided with completion, is preserved amended parameter by the SET key.
