A kind of well lid motion state monitoring device based on wireless charging technology
Technical field
The utility model relates to a kind of well lid motion state monitoring device based on wireless charging technology.
Background technology
Well lid motion state monitoring device major function accomplishes judge accurately and accomplish Timeliness coverage to the disappearance of well lid or damage, and alarm, and this device must be arranged on below well lid.Because well lid is used for sewer, the inside environment very severe, moist, high temperature with corrosive gas, so require that monitoring device will accomplish waterproof, impermeable.The long-term normal work of such guarantee device.Reach such protection effect, best mode is sealing, exactly all circuit and supplying cell one are reinstated sealant sealing extremely inside a housing, after reaching sealing effectiveness, how to carry out when device electricity is finished recharging be exactly one will faced by problem.
Well lid motion state monitoring device on the market all needs to change battery, but so just necessarily require device to open, this just just reduces the sealing of device, and long-term work is certain to the aging of electronic component in accelerator, has a strong impact on the useful life of system.The utility model adopts encapsulation process first, and adopts wireless contactless charging.

Embodiment
As shown in Figure 1, the utility model one embodiment comprises electric energy radiating portion and electric energy receiving unit; Described electric energy receiving unit comprises energy conversion unit, and described energy conversion unit is connected with receiving coil, charging circuit, control circuit; Described receiving coil and described transmission coil communication; Described electric energy radiating portion and electric energy receiving unit are sealed in two shells respectively, and described two shells are all fixed on well lid.
As shown in Figure 2, described energy conversion unit adopts BQ51013 chip; LTC4054 chip power input is connected with described BQ51013 chip.
As described in Figure 3, described charging circuit adopts LTC4054 chip; Described LTC4054 is connected with lithium battery.
As shown in Figure 4, described control circuit comprises main control module, Gravity accelerometer, wireless communication module; Described Gravity accelerometer, wireless communication module are all connected with described main control module; Described wireless communication module is connected with monitor terminal.Main control module, wireless communication module are all connected with Power Management Unit, and main control module, Power Management Unit are connected with lithium battery.Main control module can monitor the electricity of lithium battery, and when electric quantity of lithium battery is low time, main control module sends order to monitor terminal, and prompting lithium battery needs charging, is now the charging of electric energy receiving unit by electric energy radiating portion.T at set intervals, wireless communication module needs to send data to monitor terminal, now main control module makes lithium battery and wireless communication module connect by controlling Power Management Unit, wireless communication module works, after data are sent, master control module controls Power Management Unit turns off, and cuts off the power supply of wireless communication module, reaches the object of saving electric energy.Power Management Unit can adopt relay to realize.
As shown in Figure 5, electric energy radiating portion adopts the radio source transmission control unit (TCU) bq500211 of Texas Instrument (TI), this chip circuit is applicable to 5 V systems, the equipment making charging panel meet radio source alliance (WPC) Qi standard safely with portable electric appts etc. combines, receive data packet communication, and efficiently manage power delivery.In addition, bq500211 also adopts the effective power of TI Dynamic Power Limit technical optimization limited power.
Described wireless communication module is GPRS module or WIFI module.
Direct current is mainly converted into microwave signal by coil and sends by the function of electric energy radiating portion (wireless charging electroplax), it is an independently device, this device, like one " pallet ", externally sends signal, as long as just can realize charging above being placed on by receiving equipment.
Electric energy receiving unit is exactly the monitoring device of sealing, and there are receiving coil and corresponding Conversion of Energy circuit in the inside, and wireless signal is converted to electric energy by primary responsibility, reaches the object to lithium cell charging.
