Embodiment one

Figure 1 is a schematic structural diagram of a marine instrument recovery indicating device provided in Embodiment 1 of the present invention. This embodiment is applicable to the recovery of the marine instrument recovery indicating device. The marine instrument recovery indicating device is combined with the marine instrument, and the marine instrument recovery indicator The device includes a power supply module 1, a detection module 2, a control module 3, and a wireless communication module 4. The detection module 2 detects whether the marine instrument recovery indicator device floats on the water surface, and controls the power supply when it detects that the marine instrument recovery indicator device has surfaced. Module 1 provides the control module 3 with a first voltage. The control module 3 outputs a control signal to the wireless communication module 4 after receiving the first voltage, and the wireless communication module 4 transmits a wireless signal for reporting the position of the marine instrument recovery indicating device according to the control signal.

Referring to FIG. 2 , in an embodiment, the detection module 2 controls the power supply module 1 to provide the control module 3 with a first voltage. As shown in FIG. 2 , the detection module 2 includes a resistor R1 , a resistor R2 , a resistor R3 , a resistor R4 and a controllable switch Q1 . The output terminal of the power supply module 1 is connected in series with the resistor R3, the resistor R1 and the resistor R2 in sequence, and then grounded. One end of the resistor R4 is connected to the node A between the resistor R3 and the resistor R1, and the other end is grounded. The control terminal of the controllable switch Q1 is connected to the node A between the resistor R3 and the resistor R1, the first conduction terminal of the controllable switch Q1 is connected to the output terminal of the power supply module 1, and the second conduction terminal of the controllable switch Q1 is connected to the control The power input terminal 31 of the module 3 . The node A between the resistors R1 and R3 is connected to the switch control terminal 32 of the control module 3 , and the node B between the resistors R1 and R2 is connected to the detection input terminal 33 of the control module 3 .

Further, the marine instrument recovery indicating device further includes a GPS module 5 , and the GPS module 5 is connected to the control module 3 for obtaining the position of the marine instrument recovering indicating device and transmitting it to the control module 3 .

In this embodiment, as shown in FIG. 3 , the resistor R2 may be a metal pipe G1 and a metal cover G2 connected at intervals by a transparent insulating material I1 . When the marine instrument recovery indicator device sinks underwater, the metal tube G1 and the metal cover G2 are connected through the seawater between the metal tube G1 and the metal cover G2. At this time, the resistance is seawater resistance, and the resistance is close to 0Ω; when the marine instrument recovery indicator When the device floats on the water surface, the medium between the metal pipe G1 and the metal cover G2 is air, and the resistance R2 is equal to infinity at this time. The resistor R2 can also be a variable resistor whose resistance value changes according to seawater pressure, the greater the pressure, the smaller the resistance value of the resistor R2.

When working, when the marine instrument recovery indicator device sinks underwater, the resistance R2 is seawater resistance, the resistance value is close to 0Ω, R1 is connected in series with R2, and then the whole is connected in parallel with R4, and then divided by the resistance R3, for example, the first voltage It can be 5V, and the resistance ratio of resistor R1, resistor R4, and resistor R3 can be 1:1:4. At this time, the voltage of node A is 0.56V. In this embodiment, the controllable switch Q1 is an npn transistor, and its turned-on control terminal The voltage needs to be greater than 0.7V. At this time, the voltage of node A is not enough to turn on the controllable switch Q1, and the control module 3 cannot work. Only the resistor R1, resistor R4 and resistor R3 consume energy in the marine instrument recovery indicator device, and the marine instrument recovery The indicating device is in the low-power standby mode; when the marine instrument recovery indicating device emerges from the water, the resistor R2 is equivalent to being disconnected, and only the resistor R4 and the resistor R3 are left to divide the voltage.

According to the technical solution of the embodiment of the present invention, only the resistors R1, R4, and R3 consume energy when the marine instrument recovery indicator device sinks underwater, and the control module 3 works only when it emerges from the water surface, which solves the energy consumption of the marine instrument recovery indicator device The problem that accounts for a very large proportion of the cost of marine instrument recycling has achieved the effect of increasing the use time of marine instrument recycling indicating devices.

The difference from Embodiment 1 is that the control module 3 in the embodiment of the present invention includes a voltage maintenance module 6 and a delay module 7, and the voltage maintenance Module 6 outputs a maintenance voltage to node A to maintain the conduction of the controllable switch Q1 after the control module connects the first voltage; delay module 7 when the node B voltage is lower than the node A voltage preset threshold exceeds the preset time threshold Afterwards, the voltage maintenance module 6 is turned off, and the output of the maintenance voltage to the node A is stopped to terminate the conduction of the controllable switch Q1.

In this embodiment, due to the impact of the waves, the marine instrument recovery indicator device will be in a situation where it will surface at one time and be submerged in sea water at one time. Improper handling will cause the instrument to restart all the time. In this embodiment, a voltage maintenance module 6 and a delay module are added. 7. After the marine instrument recovery indicating device surfaced, the control terminal of the controllable switch Q1 is turned on after receiving the maintenance voltage, the control module 3 receives the first voltage output by the controllable switch Q1, and the control module 3 passes the switch control terminal 32 Output the maintenance voltage to node A, the maintenance voltage is a voltage that can meet the conduction condition of the controllable switch Q1, maintain the conduction of the controllable switch Q1, and the control module 3 can always receive the first voltage output by the controllable switch Q1, without affecting the use ; At the same time, the detection input terminal 33 of the control module 3 detects the node B voltage. When the node B voltage is lower than the node A voltage preset threshold, for example, the node B voltage is the voltage of the resistor R2, and the resistor R2 is a seawater resistance. close to 0Ω, the preset threshold can be the voltage of the resistor R1, the control module 3 turns off the voltage maintenance module 6 after delaying the preset time threshold, and stops outputting the maintenance voltage to node A to terminate the conduction of the controllable switch Q1, the preset time The threshold may be 10s. If within the preset time threshold, the voltage of node B is equal to the voltage of node A or the difference is not greater than 0.01V, the delay time is reset.

In the technical solution of this embodiment, through the control module 3, the voltage maintenance module 6 outputs the maintenance voltage to the node A after the control module is connected to the first voltage to maintain the conduction of the controllable switch Q1; When the voltage is lower than the preset threshold of node A voltage and exceeds the preset time threshold, the voltage maintenance module 6 is turned off, which solves the problem of continuous restart of the marine instrument recovery indicator device due to the influence of sea waves, and achieves the ability of the marine instrument recovery indicator device to withstand the influence of ocean waves.
