This embodiment of the device, in which the actuator in the electronic locking device is made in the form of an electric motor with a gearbox, allows the valve to move without the efforts of hands, the use of an electric motor with a gearbox eliminates the use of a voltage converter. The compact details of the electronic lock ensure its use in padlocks, and the introduced motor current sensor serves to determine the position of the valve in extreme positions, which eliminates the use of short-lived contacts. The key contains a power supply element that ensures operation of both the key, the lock and the electric motor in the lock, as well as the introduction of a biometric identifier in the key helps to prevent unauthorized use of the key in case of theft or loss. The introduction of the GSM module contributes to providing additional remote communication with the dispatcher or access control system and when setting up a key that gives permission for each opening or closing of the lock, all parameters are programmed in advance and can be either partially or completely disabled programmatically, and the introduction of light-sound alarm provides light and a sound signal when the lock is fully opened or closed.

The electronic locking device consists of an electronic lock 14 and an electronic key 15. The lock 14 contains a unit for connecting to a key 6 made by electrical contacts or a contactless unit for receiving energy and data from the key to the lock by means of electromagnetic energy reception or a light energy receiver, electronic lock unit 5 made on the microcontroller, the current sensor 4 is made in the form of a resistor or other element that allows you to register current, an electric motor 3. gearbox 2, a valve 1 located on the output shaft gearbox 2.

The key 15 consists of a unit for connecting to the lock 7 made of electrical contacts or a non-contact unit for transmitting energy and data from the key to the lock by means of electromagnetic energy transfer or a light energy transmitter, an electronic unit 8 made on a microcontroller, and key control elements connected to the unit 8 and lock 9, biometric reader 10, light and sound alarm 12, GSM-module 11, the power source is made on rechargeable batteries 13.

The inventive device operates as follows.

The electronic lock is in the open or closed state, the user connects the electronic key, on the controls 9 presses the "open" (not shown) or "close" (not shown) button, the electronic lock 8 is powered by a battery 13 and gives an encrypted signal through block 7 to the key, the command also activates the circuit for converting electrical energy (not shown) into electromagnetic radiation or light radiation if the circuit for transmitting energy via electrical contacts is not used, thereby informing the connection unit I to key 6 in it, electromagnetic energy or light is converted into electric current, which is necessary to power the electronic unit of the lock 5 and the electric motor, in the electronic unit of the lock 5, the dynamically encrypted command from the key is decrypted and executed when the key coincides with the lock, the electronic block of the lock 5 through the control circuit (not shown) the electric motor supplies voltage in the required polarity to the electric motor, the electric motor through the gearbox rotates the valve, when the valve reaches the extreme position The gate valve stops and the electric motor at the time of stopping consumes several times more current, which in turn registers the current sensor 4 and the electronic unit disconnects the power from the electric motor, then gives the key to the key to complete the operation, the key gives a corresponding higher signal to the sound and sound alarm 12 tonality and color.

If the “open” key was pressed (not shown), and the lock is already open, then the corresponding signal of lower tonality is output to the sound and sound alarm 12.

If the key is programmed in this way and does not have access to open this lock, then the lock gives a command to prohibit opening, which will be signaled by a light and sound alarm 12.

The GSM module and biometric reader 10, 11 are additional elements for monitoring and identifying the user and work in the key both jointly and separately from the circuit, depending on how the key is programmed through the GSM channel, information about each operation can be transmitted or approval for making an operation, a full key lock and a ban on opening a lock can also be carried out.

It is also possible to connect other elements to the key circuit for identification or additional radio transmitting units for the key to work together with a car alarm or remote gate opening.

When programming keys and locks, you can make one key open up to 10,000 locks and more or more keys can open the same lock.

Unlocking and locking the lock is carried out only with an electronic key, and not with additional keys; to unlock or lock the lock, you only need to connect the electronic key and wait for the light and sound signaling to complete the operation, the operation time does not exceed 1 s. In the inventive lock there are no electronic contacts to determine the location of the valve, which can quickly wear out and fail, this function is performed by the current sensor for the electric motor, when the valve reaches its extreme position, the electric motor stops, thereby allowing a greater current to flow, which is registered by the electronic lock unit. The small-sized low-voltage electric motor from 0.5 to 4.5 V together with the gearbox provide a torque up to 6 kg \ cm, which is necessary for unlocking and locking the valve, which allows the circuit to be used in padlocks with small dimensions. The lock does not need an additional programmer, the key performs this function, with a certain programming of the key, the key becomes the programmer. The introduction of a biometric reader into the electronic key allows you to identify the user and will not allow unauthorized entry if the key is stolen or lost. The GSM module provides additional control over the operations performed and, if necessary, you can block the key via the GSM channel at any point where there is a GSM connection, you can also program key, so that without confirmation via GSM channel it was impossible to perform any operation. The key and lock can be connected via a non-contact method of transmitting data and energy, by means of electromagnetic energy transfer or light energy transfer, which ensures long-term operation of the device connecting the key to the lock, as electrical contacts need maintenance and are not durable.
