Description

Technical Field

[0001] The invention relates to a power plug lock control device. Background Art

[0002] Laboratory instruments and equipment are very important material conditions to ensure the normal progress of scientific research. If the instruments and equipment are used improperly, they are easy to be damaged, which will not only cause economic losses, but also affect the progress of the experiment. Therefore, it is necessary to effectively manage the use of instruments and equipment, such as training operators, authorizing the use of instruments and equipment, inspecting and recording the use process of instruments and equipment, and maintaining instruments and equipment after use, etc., especially in scenarios with many users. At present, there are many types of laboratory instruments and equipment in universities, enterprises or scientific research institutions, and there are many users. Many instruments and equipment do not have user identification and login functions. Special personnel are required to implement training, authorization, inspection, recording, maintenance and other management, and the management cost is high. In addition, the utilization rate of instruments and equipment in many research institutions is low. These fixed assets can be revitalized through sharing, but the high labor management cost hinders the realization of sharing.

[0003] In response to the above problems, the prior art has provided some solutions, mainly adding a power controller that can identify the user to control the switch of the instrument and equipment, thereby realizing automatic authorization management of the user. The disadvantage of this method is that it has relatively high requirements on the stability and reliability of the power controller. If the abnormal power outage of the instrument and equipment is caused by the failure of the power controller, it will cause damage to the instrument and equipment, and even directly lead to the failure of the experiment, which may cause immeasurable losses. In order to ensure high reliability, the cost of the power controller must be greatly increased, which will eventually lead to an increase in management costs. The power of different instruments and equipment varies greatly, and power controllers with different rated powers need to be produced. Therefore, it is necessary to propose a new solution to the above defects to avoid using relays to directly control the power supply of instruments and equipment. Summary of the invention

[0004] The object of the present invention is to provide a power plug locking device, which has a simple structure, low implementation cost, and is safe and reliable to use.

[0012] Open the control compartment door and the power plug storage compartment door, put the power plug into the power plug storage compartment, and pass the power cord through the passage connecting the power plug storage compartment and the control compartment and the gap connecting the control compartment with the outside world;

[0013] After the control compartment door is closed, part of the power cord is exposed outside the power plug lock control device, and the power plug cannot be removed by pulling the power cord, thus achieving the binding of the power plug lock control device and the power plug of the instrument and equipment;

[0014] When the user opens the door of the power plug storage compartment, the power plug can be taken out. At this time, due to the obstruction of the power cord, the door of the power plug storage compartment cannot be closed. Only when the power plug is put back into the power plug storage compartment can the door of the power plug storage compartment be closed;

[0015] The electric lock on the door of the power plug storage compartment feeds back its opening and closing status to the control and communication unit, thereby determining whether the instrument equipment is in use.

[0016] Compared with the prior art, the present invention has the following beneficial effects: a power plug lock control device is provided, which does not use a relay to directly control the current of the instrument and equipment, thereby avoiding abnormal power outage of the instrument and equipment due to a relay failure. The present invention only uses an electric control lock and a simple control chip, with a simple structure, low cost and high reliability. Through the simple hardware provided by the present invention, with the help of powerful mobile phone APP, WeChat applets and other software and background servers, automated management of the use training, reservation, authorization, charging, inspection, recording, maintenance and other aspects of the instrument and equipment can be realized, greatly reducing labor costs and improving management efficiency.

[0022] like Figure 1 As shown, this embodiment provides a power plug lock control device, including a power plug storage compartment 1 and a control compartment 5, wherein the power plug storage compartment 1 is used to store power plugs, and the control compartment 5 is provided with a control and communication unit, and the control and communication unit is used to communicate with the outside world, receive external control signals to open the compartment door of the power plug storage compartment, and send the opening and closing status information of the power plug storage compartment to the outside world.

[0023] The power plug storage bin 1 is provided with a storage bin door 3 and a storage bin electric lock 2. The storage bin door 3 is controlled to open by the storage bin electric lock 2. The storage bin electric lock 2 is electrically connected to the control and communication unit, and is controlled to open by an electrical signal sent by the control and communication unit, and its switch state is fed back to the control and communication unit. The storage bin electric lock 2 is directly locked by a mechanical external force. In this embodiment, the storage bin electric lock uses a titanium wire lock with a simple structure, which is opened by a high-level electrical signal, directly locked by an external force, and its switch state is fed back to the control and communication unit by a pair of signal lines. Closing the storage bin door 3 means that the instrument equipment has been used.

[0024] The control compartment 5 is provided with a control compartment door 4, which can be opened by the control compartment electric lock 6, or locked by a mechanical lock or a lead sealing device, and is only for administrators to use. In this embodiment, the control compartment electric lock is opened by another titanium wire electric lock, and ordinary users have no authority to open the control compartment door, and only administrators can open it.

[0025] In this embodiment, the control compartment 5 is provided with a gap 7 communicating with the outside to allow the power cord to pass through; the power plug storage compartment 1 and the control compartment 5 are connected by a channel 8 to allow the power cord to pass through, but not the power plug.

[0026] The control and communication unit can be composed of a control chip and a communication chip, or a chip integrating control and communication.
