Low-current short-distance digital lock control device and control method

Abstract

The invention provides a low-current short-distance digital lock control device and a control method. Comprising a control host and a lock controller connected with the control host, wherein the control host is used for sending a first level signal or a second level signal to the lock controller, the first level signal is used for triggering the lock controller to open the lock mechanism, and the second level signal is used for triggering the lock controller to close the lock mechanism; and the controller is also used for receiving a state signal from the lock controller. The control host receives a control command of the lock control operation to generate a first control instruction; the control host sends a first control instruction to the lock controller to drive the lock controller to execute; meanwhile, the control host receives state information sent by the lock controller and updates the state of the lock controller. The lock controller is controlled by the control host through different level signals, so that the lock mechanism is opened and closed, the state of the lock controller can be monitored in real time, line design can be performed at low cost, and low-current short-distance real-time lock control state control and monitoring can be realized.

Description

technical field [0001] The present application relates to the technical field of intelligent control, and in particular, to a low-current short-distance digital lock control device and a control method. Background technique [0002] With the development of intelligent control technology, especially the development of Internet of Things technology, people's lifestyles have undergone tremendous changes. In the past, people traveled and purchased face-to-face communication and transactions in physical stores and store personnel. With the emergence of unmanned sales, the store is no longer equipped with staff to provide sales services, but consumers make purchases in the store and complete the transaction. This method is novel and convenient, and can achieve 24-hour sales operations. On the one hand, it further provides consumers with the convenience of shopping, and on the other hand, it also improves the duration and efficiency of store operations, which is conducive to incre...

Problems solved by technology

The advantage of this mode is that the communication distance is long, the driving current is large, and the current can reach tens of milliamps, but the control method is not flexible, which is reflected in the inflexible control of the opening time, and the opening and closing of the digital lock cannot be sensed for a period of time after the door is opened. state

As a result, the deterministic operation of the lock controller cannot be performed in time to ensure that the lock controller is in a proper state and ensure the interests of consumers and merchants

[0006] In fact, in the scenario of unmanned retail cabinets, the communication distance between the lock control and the control host is generally small. The original rs485 serial port communication lock control long-distance feature is no longer important, but has become an irrelevant function.

In addition, the control of the lock controller by the rs485 serial port requires a large driving current, which also increases the power consumption to a certain extent. In the view of the lock controller that frequently uses the rs485 serial port for operation, it is quite expensive
