Detailed Description
The invention is further described with reference to the following drawings and detailed description.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the digital intelligent encryption valve comprises a valve cover 1 and a valve rod 2, the innovation of the mechanical structure is that the upper end of the valve cover 1 is connected with a transmission sleeve 3 connected with the top end of the valve rod 2, the upper end of the transmission sleeve 3 is provided with a force transmission disc 4 in a suspension way through a spring, the lower end of the force transmission disc 4 is provided with a pin which can be matched with a pin hole on the transmission sleeve 3, and when the encryption valve is in an open state, the pin is inserted into the pin hole; in the non-opening state, the pin is separated from the pin hole, and torque cannot be transmitted. The upper end of the force transmission disc 4 is connected with an electromagnet 5 and an electromagnet control circuit module 14, the electromagnet 5 and the electromagnet control circuit module 14 are fixed on the outer sleeve 6, and the electromagnet control circuit module 14 is arranged beside the electromagnet 5 and used for driving the electromagnet 5. In addition, the tool body 8 capable of being assembled on the outer sleeve 6 is further included, a power supply 9, a power supply circuit constant voltage module 10, a circuit protection module 11 and a switching circuit module 12 are arranged in the tool body 8, and the power supply 9 is a lithium battery.
In this embodiment, as a connector that is necessary to open and close the valve, a cable plug 13 is further included, one end of the cable plug 13 is normally connected to the power supply 9 through the circuit protection module 11 and the power supply circuit constant voltage module 10, and the other end is plugged into the electromagnet control circuit module 14 under an operating condition.
As shown in fig. 2, in the present embodiment, the power circuit constant voltage module 10, the circuit protection module 11 and the switch circuit module 12 respectively include a power circuit constant voltage circuit, a protection circuit and an interaction circuit. Specifically, the power supply circuit uses the integrated chip AMS1117 and the peripheral circuit to provide a constant voltage of 5 v; the protection circuit effectively avoids external voltage damage by using TVS to absorb instantaneous high voltage, and has a short-circuit protection function; when the intelligent encryption valve is used, a user can obtain real-time sound signals (specific dripping sound) so as to determine the working state of the valve.
As shown in fig. 3, in the present embodiment, the electromagnet control circuit drives the relay by using a triode to indirectly drive the electromagnet 5, or directly drives the electromagnet 5 by using a thyristor, and the encryption control circuit operates the EEPROM by using the micro-singlechip, and processes data by using a set of encryption algorithm, thereby ensuring that the data cannot be decrypted by 100% basically.
As shown in fig. 4, when data is stored in the EEPROM, the specific work flow is to fill up the random number string for storage, then store the unique number of each product in a designated location (different use occasions have different passwords, and we can know who the product is sold for through the number, the shipment time and other information), and finally determine two groups of numbers specific in the designated area, and after the stored data is determined to be error-free through comparison, prompt the buzzer to send a signal to confirm whether to write in the data through the exchange circuit module 12.
As shown in fig. 5, the encryption control is to read the designated array in the memory, and a value is obtained through a series of function processing, when the value is correct, the micro-singlechip sends out a signal for driving the electromagnet 5, the buzzer can be turned on and off by dropping two sounds, and the buzzer warns when the buzzer sounds all the time. The detailed working principle of fig. 5 is that the cat can be observed by peeping the spot, and the detailed description is omitted here.
When the valve operates, the inner hexagon inside the tool body 8 is clamped with the outer hexagon on the outer sleeve 6, after the plug 13 is connected with the electromagnet control circuit module 14 and is decrypted according to the principles of fig. 4 and 5, the electromagnet 5 extends out of the iron core to push the force transmission disc 4, the pin of the force transmission disc 4 is matched with the pin hole of the transmission sleeve 3, and external force rotates the outer sleeve 6 through the pull rod 7, so that the valve rod 2 is driven to rotate, and the valve is opened and closed. If the decryption is not passed, the electromagnet 5 does not act, the force transmission disc 4 is separated from the transmission sleeve 3, and the valve cannot be opened or closed. In addition, when the tool body 8 is removed and the plug 13 is pulled out, the electromagnet control circuit module 14 is powered off, the electromagnet 5 does not act, the outer sleeve 6 can rotate freely, and the valve cannot be opened or closed because the force transmission disc 4 is separated from the transmission sleeve 3.
The utility model has simple structure and reliable control, and can be widely applied to occasions requiring control on opening and closing of the valve.
The above description is illustrative of the present invention and is not to be construed as limiting the invention, which is defined in the appended claims, as it may be modified in other forms without departing from the basic inventive concept.
