Specific embodiment
The utility model is described in further details below with reference to Figure of description and specific embodiment.
The utility model is a kind of contactless well lid Detection of Existence system, uses the principle of ultrasonic distance measurement indirect
Measurement well lid is realized the inclination of well lid at a distance from ultrasonic probe apparatus point, is opened.As shown in Figure 1, the utility model
Contactless well lid Detection of Existence system is visited including well lid monitor 5, transmitting-receiving integrated ultrasonic probe 2 and ultrasonic wave
Head fixes bracket 1, has well lid 6 on kiln well 7, ultrasonic probe 2 passes through fixed bracket 1 and installs on the wall of kiln well 7, with well lid 6
Upper edge distance about 40mm, ultrasonic probe 2 is connected in well lid monitor 5 by lead 3, and well lid monitor 5 is by safety
It is suspended on the borehole wall after wire saws.When ultrasonic wave works, ultrasonic probe 2 issues sound wave 4, and sound wave 4 is returned by 6 back side of well lid resistance shelves
Huis wave.Well lid monitor 5 receives echo post analysis backward energy and the time difference, to obtain the phase of ultrasonic probe 2 with well lid 6
To position.
As shown in Fig. 2, well lid monitor 5 includes low-power consumption MCU, ultrasonic drive circuit, indigo plant in specific application example
Tooth circuit, NB-IoT circuit and electric power management circuit and battery.To solve the problems, such as to take electric difficulty, well lid prison in kiln well 7
It surveys device 5 and uses storage battery power supply, and entire product is designed using extremely low power dissipation, it is low if MCU uses TI company CC series monolithic
Power consumption wide area network NB-IoT communications module, low-power consumption bluetooth mould group, low consumption low voltage ultrasonic drive circuit.Entire monitor
Combinational dormancy electric current is up to 20uA or less.Low-power consumption wide area network NB-IoT communication has stronger communication capacity, overcomes 2G letter
The problem of signal is weak number under kiln well lid or no signal, has ensured the base station normal communication of well lid monitor operator, and be not necessarily to group
Net.Low-power consumption bluetooth module is using intermittent broadcast mechanism, and in the connection of no applications equipment, operating current is no more than 5uA,
And after outside sets connection, parameter configuration, program radio upgrade can be carried out to monitor.External equipment (such as cell phone application) can be real
Now with the real time communication of monitor, convenient for the installation and debugging and diagnosis of product.Ultrasonic drive circuit completes ultrasonic wave modulation
With demodulation, according to the measured time difference and echo strength, MCU is calculated when time distance of measurement, this distance and set threshold
Value compares to obtain whether current well lid is translated, opens, tilts etc..Ultrasonic drive circuit has power control function, not
When work, the power supply of entire circuit is disconnected, zero-power, when needing to detect, is opened power supply, is closed after completing single or multiple measurements
Power supply is closed, to realize low-power consumption.
