[0037] The parameter adjustment module 103 is used to input parameter adjustment instructions, wherein the parameters at least include zoom parameters, focus parameters and aperture parameters of the lens;
[0038] The parameter control module 104 is used to adjust the parameters of the lens according to the parameter adjustment instruction.
[0039] In the above implementation process, the lens control device adjusts the current and parameters passing through the lens according to different needs by setting a current adjustment module and a parameter adjustment module, thereby improving the adjustment reliability and accuracy. The overall structure is simple, the reliability and accuracy are high, and the optical lens can be adjusted quickly and accurately.
[0040] like Figure 2 As shown, the lens control device in the embodiment of the present application includes a current regulating module 101, a current control module 102, a connection module 103, a parameter regulating module 103 and a parameter control module 104, wherein the current control module 102 adopts the LM2596 step-down power management chip for outputting a driving current of 3A and having good linearity and load regulation characteristics, and the parameter control module 104 is ULN2003, which is a composite transistor array and has the characteristics of high current gain, high operating voltage, wide temperature range, strong load capacity, etc., and is suitable for various systems requiring high-speed and high-power driving.
[0041] The control method of the lens control device is controlled according to the following workflow:
[0042] 1) Connect the power supply and lens control wiring;
[0043] 2) Move the lever to control the zoom, focus, and aperture of the lens;

[0047] like Figure 5 As shown, the connection module in the embodiment of the present application includes a plurality of relays Relay-SPDT, which can be an electromagnetic relay. Electromagnetic relays are generally composed of an iron core, a coil, an armature, a contact spring, etc. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect, and the armature will overcome the pulling force of the return spring under the action of electromagnetic attraction and be attracted to the iron core, thereby driving the moving contact of the armature and the static contact (normally open contact) to attract. When the coil is powered off, the electromagnetic attraction also disappears, and the armature will return to its original position under the reaction force of the spring, so that the moving contact and the original static contact (normally closed contact) are released. In this way, the attraction and release achieve the purpose of conduction and disconnection in the circuit. For the "normally open, normally closed" contacts of the relay, it can be distinguished as follows: the static contact in the disconnected state when the relay coil is not powered is called the "normally open contact"; the static contact in the connected state is called the "normally closed contact". Among them, the switching pin of the relay is the switching switch K1, the other end of the switching switch is connected to the six pins of the lens through the terminal block, one end of the coil is connected to the 12V power supply, and the other end of the coil is connected to the parameter control module.
