Description of drawings
Fig. 1 is the module connection diagram of a kind of wireless alarm electric quantity monitoring device of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the embodiment of utility model is described further.Following examples only are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of wireless alarm electric quantity monitoring device as shown in Figure 1, comprise connect in turn battery, detecting module, coding module and and wireless transmitter module; After detecting module trigger to be reported to the police, coding module sent the address code of a regular coding by wireless transmitter module, after alarm host machine is received this address code, sends note by network and sends warning message to the first-class mode of user's mobile phone to the user; Main improvements of the present utility model are, also comprise the electric quantity monitoring module that is connected with battery and the time block that is connected with coding module with the electric quantity monitoring module respectively; The electric quantity monitoring module monitor in real time battery electric weight and electric weight be lower than power threshold (for example battery electric quantity be lower than the highest electric weight 30 percent) time start time block, time block timing controlled wireless transmitter module is sent to alarm host machine with the low electric weight sign indicating number of the expression battery electric quantity deficiency that coding module generates, the alarm host machine notice is also reminded the user, and the battery of this wireless alarm needs to change.
Wherein, the electric quantity monitoring module comprises divider resistance and connected control circuit; Divider resistance connects battery, and control circuit connects time block; Control circuit starts time block during less than preset value in total dividing potential drop of divider resistance; In the present embodiment, the electric quantity monitoring module comprises two divider resistances, and control circuit mainly is made up of two triodes; Battery electric quantity just often total partial pressure value of two divider resistances is not less than preset value, and by the power-off of control circuit with time block, time block is not worked; When total partial pressure value less than preset value, be that (relation of cell voltage and electric weight is non-linear to battery electric quantity when being lower than described power threshold, relevant with the model of battery, amount of capacity etc., Ni-MH battery as 9V, 180mAh, when voltage is lower than the 7.8V left and right sides, battery electric quantity has been lower than 30%), control circuit is opened for the power supply of time block power supply, starts time block.
Wherein, time block comprise respectively with control circuit be connected with coding module the time base chip and with the time base chip power supply that is connected; In the present embodiment, base chip when time base chip is ambipolar (555 o'clock base chips); The base chip operation is in the astable multivibrator pattern when making, and its oscillation period and dutycycle determine by charging, the discharge time constant of being made up of charging resistor, discharge resistance, charge and discharge capacitance; The output duration of constant control conduction time high level, charging rate and discharge time constant are controlled oscillation period together, i.e. the timing cycle of time block; High level by output triggers wireless transmitter module and will hang down the electric weight sign indicating number and launch, the output duration of this high level must guarantee that wireless transmitter module will hang down the electric weight sign indicating number and effectively launch, but should consider life-span of battery consumption and wireless transmitter module, as far as possible for a long time emission and emission cycle unsuitable oversize; These requirements can be by well-designed resistance value, capacitance, and a large amount of experiments realizes.
Wherein, the low electric weight sign indicating number that coding module generates and address code are corresponding and do not disturb mutually one by one, so just can not influence the warning that normal address code causes; If namely alarm host machine is received low electric weight sign indicating number, just show it is the low prompting of battery electric quantity, if receive that it is warning message that address code just shows, before running down of battery, can also Normal Alarm if there is warning to trigger.
Be that example describes with the battery powered infrared radio alarm of 9V now: after the start of infrared radio alarm powers on, the electric quantity monitoring module is just monitored cell voltage (divider resistance be respectively 20,000,000 beat up with 720,000 beat up) always, when cell voltage is lower than 7.8V, time block just powers up and starts working, we set timing is 15 minutes, after arriving in 15 minutes, time block is namely controlled wireless transmitter module the low electric weight sign indicating number that coding module generates is sent; After alarm host machine is received low electric weight sign indicating number, determine the low information of battery electric quantity that the infrared radio alarm is sent, just send note to user's mobile phone by network, remind the user, the battery of this infrared radio alarm needs to change; Simultaneously, before running down of battery, can also Normal Alarm if there is warning to trigger.
A kind of wireless alarm electric quantity monitoring device of the present invention has the following advantages:
1, the timely reminding user to replace battery of energy when battery electric quantity is low can not lose efficacy wireless alarm owing to battery electric quantity exhausts;
2, the user does not need regularly to go to check that the battery of alarm has and do not have electricity, has saved time and efforts;
3, avoided having the characteristics of environmental protection because battery electric quantity exhausts the possibility that leakage causes wireless alarm to be corroded.
Above embodiment only is used for explanation the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make a variety of changes and modification, so all technical schemes that are equal to also belong to protection category of the present utility model.
