Description
Technical field
The utility model relates to a kind of device for detecting temperature, specifically is a kind of wireless temperature measuring device.
Background technology
For a long time, owing to having exposed high pressure and space narrow and small relatively in the switch cubicle that need carry out monitoring temperature, temperature acquisition mode just commonly used now, as optical fiber temperature-measurement: fibre optic temperature sensor adopts the fiber optic transmission temperature signal, light transmitting fiber has excellent insulating property, high pressure in can isolating switch cabinet, therefore fibre optic temperature sensor can directly be installed on the interior high-voltage contact of switch cubicle, accurately measure the running temperature of high-voltage contact, realize the on-line monitoring of switch cubicle contact running temperature.Yet the optical fiber surface that is used for isolated high-voltage may be polluted, and will cause the optical fiber creeping discharge.This thermometric that makes optical fiber temperature measurement system be used for outdoor switch equipment is used and is restricted.Infrared measurement of temperature: infrared measurement of temperature is a contactless temperature-measuring, be subject to the environment and the interference of electromagnetic field on every side, space in the switch cubicle is very narrow and small in addition, infrared temperature probe can't be installed, because probe must keep certain safe distance with testee, and need be over against the surface of testee, and infrared temperature-measuring gun also can't normally be measured in intermediate switchgear cabinet.
Traditional temperature acquisition mode can't satisfy in real time the demand of collecting temperature accurately.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of wireless temperature measuring device that can accurately measure temperature and data can be carried out wireless transmission and precaution alarm in narrow and small switch cubicle.
The technical scheme that its technical matters that solves the utility model adopts is: this wireless temperature measuring device comprises high energy power supply, temperature acquisition chip, logic analysis circuit, real-time clock module, radio receiving transmitting module.
The high energy power supply provides the electric power supply of package unit, the surface of contact employing of described temperature acquisition chip is close to contact or the mode on the cable splice that will measure and is carried out temperature survey, can be real-time temperature be gathered, it with the logic analysis circuit between carry out circuit and be connected, the temperature information of being gathered is transferred to the logic analysis circuit; The temperature information that described logic analysis circuit reception temperature acquisition chip is gathered is handled, and determines whether the equipment in the switch cubicle is overheated, to determine whether sending warning message.Described Logic Analysis circuit connects radio receiving transmitting module, and passes through it to temperature indicator communication.
As further technical scheme of the present utility model be:
Store in the described logic analysis circuit and make it judge whether the alarm temperature critical value of reporting to the police and exporting.If do not surpass alarm temperature, then carry out the transmission of data by the pre-set time, if exceeded alarm temperature, then a real-time clock module that is connected with the logic analysis circuit sends it is waken up information, and the logic analysis circuit is given the alarm to temperature indicator by radio receiving transmitting module.
Radio receiving transmitting module adopts the RF radio communication that forms based on the zigbee technical design that is operated in 2.4GHZ.Described high energy power supply can adopt 1.2AH high energy lithium Ammonium powered battery.
Described temperature acquisition chip adopts AD7416 type digital temperature sensor.
The beneficial effects of the utility model are: can have the narrow and small relatively artificial inspection that can reduce in exposed high pressure and space to measure number of times interior, alleviate the labour.At the shortcoming of existing thermometric mode, made correction, reduced the influence that external environment causes temperature survey, this equipment power dissipation is extremely low and adopt high energy lithium Ammonium battery, can continued power 3-5.Be specially adapted to the temperature survey under enclosed high-tension switch cabinet and the various hyperbaric environment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1; this kind device for detecting temperature; comprise a high energy power supply; described high energy power supply adopts high energy lithium Ammonium battery (1.2AH) and an electric power management circuit to form; the center section that is positioned at equipment is responsible for the power supply of entire equipment; keep the normal operation of equipment, and the safety of protection equipment.The logic analysis circuit receives the data that the temperature acquisition chip sends, and data are analyzed, handled.Real-time clock is responsible for waking up of equipment.The temperature acquisition chip is responsible for collecting temperature information.Radio receiving transmitting module adopts the RF radio frequency based on the 2.4G wireless transceiver circuit of zigbee technology, will send to temperature indicator through the data that the logic analysis processing of circuit is crossed.
The surface of contact of temperature acquisition chip is fixed on the contact or cable splice that needs to measure, the temperature acquisition chip just can be sensed variation of temperature in real time, and real time temperature gathered, the real time temperature information that collects is sent to the logic analysis circuit, MCU microprocessor in the logic analysis circuit will be analyzed the temperature of determining this moment to real-time temperature information and whether surpass the early warning temperature, then do not send warning message if surpass the early warning temperature, information temporary storage is also regularly sent by the RF radio frequency of radio receiving transmitting module, if surpass the early warning temperature, then real-time clock module can to equipment wake up MCU can with this moment temperature send by the RF radio frequency immediately, and on the thermometric display instrument display alarm information.
For reaching the purpose of power and energy saving, when temperature did not normally surpass the early warning temperature, equipment was in dormant state, be the data that timed sending collects, equipment just is in operating condition when sending data, is responsible for conversion to the transfer process of running by real-time clock module by dormancy, promptly wakes up.If temperature surpasses the early warning temperature, then real-time clock can wake entire equipment up immediately, outwards sends a warning message.
