There are the patient of old man, children, special constitution person and handicapped recuperation of being in, general feelings in many families It is difficult to ensure that 24 hours someone follow treatment under condition, if there is accident, it cannot often be found in time, thus cannot be timely Treatment, consequence is hardly imaginable, therefore a kind of equipment in case of emergency facilitating calling for help is most important, most common method It is to be called for help by communication tools such as mobile phones (smartwatch), this can solve problem, but defect really in any case It is to often forget about charging it will be evident that be very power consumption first, and some old men have a bad memory, followed by signal covers bad, ground Some frequent no signals in place such as in lower room, building, third problem is made a phone call for handicapped person or burst Loss of consciousness etc. be in special circumstances be difficult to operate, therefore need to develop a kind of low-power consumption, can it is standby for a long time, signal is strong, behaviour Make simple emergency call system.

Utility model content

It solves urgent help caller stand-by time in the prior art not grow, the defect that needs often to charge, the utility model Provide a kind of low-power consumption distress call device.The utility model specific technical solution is as follows:

The utility model provides a kind of low-power consumption distress call device, the low-power consumption distress call button system device packet Include low-power consumption distress call device, which is characterized in that low-power consumption distress call device include shell, be set to it is urgent on shell Button and it is set to the intracorporal circuit board of shell, MCU, power module, NB-IOT communication module, positioning mould are respectively equipped on circuit board Block and relay, power module, danger button, communication module, locating module and relay are connected with MCU, locating module Also it is connect with relay.

Further to improve, locating module is one of GPS module or Beidou positioning module.

Further to improve, the pin 15 of MCU is connected with one end of first capacitor and crystal oscillator respectively, the pin 16 of MCU It is connected respectively with the other end of one end of the second capacitor and crystal oscillator, the other end of the other end of first capacitor and the second capacitor connects It is grounded after connecing.

The beneficial effects of the utility model are as follows: low-power consumption distress call device provided by the utility model makes rescue beacon Average power consumption reduces, so that the long-term normal use of rescue beacon can obtain permanent, reliable guarantee, realizes for a long time not With charging, and while operating, need to only press a danger button, a key operation, simple and convenient.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the low-power consumption distress call device of embodiment 1；

Fig. 2 is the circuit diagram of the low-power consumption distress call device of embodiment 1.

Specific embodiment

The utility model is described in further detail with following embodiment with reference to the accompanying drawing, in order to express clearly, this Each component has carried out corresponding scaling in the attached drawing that utility model provides.

Embodiment 1

Embodiment 1 provides a kind of low-power consumption distress call device, as depicted in figs. 1 and 2, low-power consumption distress call dress It sets including shell 1, the danger button being set on shell 15 and the circuit board 2 being set in shell 1, is set respectively on circuit board 2 There are MCU3, power module 4, NB-IOT communication module 6, locating module 7 and relay 9, power module 4, danger button 5, communication Module 6, locating module 7 and relay 9 are connected with MCU3, and locating module 7 is also connect with relay 9, and locating module 7 is One of GPS module or Beidou positioning module.

Wherein, the MCU in the present embodiment use STC12C5A16S2 single-chip microcontroller, the single-chip microcontroller respectively with locating module and The connection of NB-IOT communication module, NB-IOT module use FSH12BC95 module, have size small, the excellent feature of performance, simply AT order communication and setting can be completed, the pin 5 of MCU is grounded after connecting with resistance R3, the pin 6 of MCUNB-IOT with draw Foot 8 is connect with communication module, is grounded after 9 connection switch of pin of MCU, and the pin 17 of MCU is grounded, the pin 26 of MCU and fixed The end VCC of position module is connect with relay, and the pin 41 of MCU is connect with power module, the end the GND ground connection of power module, fixed Position module is using ATGM336H, it provides GPS and the positioning of Beidou bimodulus, and small in size, structure is simple, 30 He of pin of MCU Pin 32 is connect with locating module, reads location information, and danger button is connect by the middle fracture of MCU with MCU, is pressed urgent Button wakes up MCU by interrupting, is ready-made mature modules with upper module, and connection is simple, at low cost, in addition, urgent when pressing NB-IOT communication module and locating module could be actively waken up after button；Working principle: low-power consumption distress call device is placed In facilitating at pressing (low-power consumption distress call device can be placed in the position stretched out one's hand and can touched by bed user), work as user MCU is waken up by lower button, MCU reads locating module information, and obtains location information, and then MCU location information and calls for help letter Breath is sent by NB-IOT communication module, NB-IOT communication module 6 and 8 communication connection of remote control center through carrier network To remote control center, remote control center receives guardian or the mechanism reinformed after calling for help information to user's registration, by NB-IOT communication module and MCU are in dormant state when button is not pressed, therefore, can save electricity significantly, drop Low average power consumption extends the time that uses of PBU pushbutton unit, the pin 15 of MCU3 one end with first capacitor 10 and crystal oscillator 11 respectively It is connected, the pin 16 of MCU3 is connected with the other end of one end of the second capacitor 12 and crystal oscillator 11 respectively, first capacitor 10 It is grounded after the connection of the other end of the other end and the second capacitor 12, it is preferable that NB-IOT communication module 6 and remote control center 8 are logical News connection, crystal oscillator, first capacitor and second capacitor etc. are the basic circuits for maintaining MCU operation.
