The embodiment of the application provides an intelligent door-closing safety interlocking device for a temporary power distribution box in a construction site, which is shown in fig. 1 and comprises the following components: the human body infrared sensor 12, the controller 11, the access control system 14, the remote maintenance end 13 and the switch mechanism 15 are arranged on the distribution box; the human body infrared sensor 12 and the access control system 14 are electrically connected with the controller 11; the remote maintenance end 13 is in communication connection with the controller 11; a human body infrared sensor 12 for detecting human body infrared on the opening side of the distribution box and transmitting the detection result to the controller 11; the access control system 14 is provided with an identity recognition module, and the identity recognition module is used for acquiring the identity information of the electrician at the construction site and transmitting the identity information to the controller 11; the controller 11 is configured to transmit the identity information to the remote maintenance end 13, receive a confirmation result corresponding to the identity information in the configuration information fed back by the remote maintenance end 13, and send an instruction for opening or refusing to open the door of the distribution box to the switch mechanism 15 based on the confirmation result; the controller 11 is further used for judging whether an electrician leaves the distribution box temporarily according to the detection result; and sends an instruction to close the door of the distribution box to the switch mechanism 15 when the electrician is detected to leave the distribution box temporarily; and a switch mechanism 15 for performing an operation of opening or closing the box door according to an instruction of opening or closing the box door.

In the present embodiment, the human body infrared sensor 12 is used to detect the movement or presence of a human body, and in particular, the human body infrared sensor 12 is used to detect the presence of a human body on the opening side of the distribution box, which is capable of sensing the thermal energy and movement of the human body using infrared radiation or pyroelectric technology, thereby obtaining the detection result.

Specifically, the human body emits infrared heat energy and is received by the human body infrared sensor 12, the human body infrared sensor 12 analyzes the received infrared signal, and generates corresponding electric signals for triggering other devices or executing specific operations after detecting the movement or heat energy change of the human body.

In this embodiment, the human body infrared sensor 12 is electrically connected to the controller 11, and when the human body infrared sensor 12 detects that the human body approaches or moves away, a relevant detection result is generated. That is, when a human body enters the monitoring range of the human body infrared sensor 12, the human body infrared sensor 12 generates a detection result that a human body exists, or when no human body is within the sensing range of the human body infrared sensor 12, the human body infrared sensor 12 generates a corresponding detection result and transmits the detection result to the controller 11.

In this embodiment, the access control system 14 is a security system of a door of a distribution box, which uses electronic equipment and is configured with an identity recognition module, and the identity recognition module is used for acquiring identity information of an electrician at a construction site and transmitting the identity information to the controller 11.

Alternatively, the access system 14 includes an access card, which may be embodied as a magnetic card, a radio frequency card, an IC card, or a virtual access card based on a mobile phone, as proof of identity authorization.

The identity recognition module can be a card reader which is used for reading identity information in the access card. Specifically, the card reader may obtain the identity information of the job site electrician through contact (e.g., inserting an access card into the card reader) or non-contact (e.g., approaching an access card to the card reader), and transmit the identity information to the controller 11.

The obtained identity information may be employee number or other identification information of the electrician at the construction site, and may further include other information of the electrician, such as a department to which the electrician belongs, whether to temporarily person, and the like.

It should be appreciated that in some embodiments, the identification module may also be implemented using techniques such as password input devices, biometric identification techniques, and the like.

In this embodiment, the controller 11 is used as a core control unit for performing various functions, such as receiving, processing and analyzing collected data, and sending out an instruction for opening or closing the door of the distribution box, so as to ensure that the distribution box is intelligently opened or closed according to preset logic, and improve the electricity safety of a construction site.

Specifically, in the present embodiment, the controller 11 executes two processing flows, which are described in detail below.

One of the processing flows executed by the controller 11: the method comprises the steps of generating an instruction for opening or refusing to open a distribution box door based on identity information, receiving the identity information from an access control system 14, transmitting the identity information to a remote maintenance end 13, inquiring whether a configuration item corresponding to the identity exists in configuration information by the remote maintenance end 13 based on the identity information, recording and storing an access card login log of an electrician, generating a confirmation result allowing the electrician to open the distribution box door, returning the confirmation result to a controller 11, generating a confirmation result refusing the electrician to open the distribution box door if the configuration item matched with the identity information does not exist, and returning the confirmation result to the controller 11.

The controller 11 acquires the confirmation result fed back by the remote maintenance terminal 13, and sends an instruction to open or refuse to open the box door to the switch mechanism 15 based on the information contained in the confirmation result that allows or refuses the electrician to open the box door.

It can be seen that in this embodiment, the conditions for opening the door of the distribution box are: and meanwhile, the electrician card swiping on the construction site can be matched by the access control system 14 to meet the condition, and then the controller 11 sends out an instruction for opening the door of the distribution box. Otherwise, if the electrician in the construction site swipes a card and matches the access control system 14, but the identity information does not exist in the configuration information of the remote maintenance end 13, or the identity information exists but the swipe time is not within the time period allowed by the remote maintenance end 13, the condition that the door of the electric box is opened is not satisfied, and once the condition is not satisfied, the controller 11 will issue an instruction to refuse to open the door of the electric box. The door opening condition of the distribution box is set to be that the remote management end is allowed to be matched with the field access control card at the same time, so that other people can be effectively prevented from opening an illegal operation switch of the distribution box, and meanwhile, the field access control card swiping confirmation and remote maintenance end 13 confirmation control mode is adopted, so that risks caused by illegal invasion (such as violent cracking) of the field access control card can be avoided.

The second process flow executed by the controller 11 is: whether the electrician leaves the distribution box temporarily is judged according to the detection result, if so, an instruction for closing the box door of the distribution box is sent to the switch mechanism 15. When the detection is specifically judged, the controller 11 analyzes the detection result, and if the analysis result shows that no personnel is in the induction range of the human body infrared sensor 12, the electrician is determined to temporarily leave the distribution box, and then an instruction for closing the box door of the distribution box is sent to the switch mechanism 15; if the analysis result shows that a person is continuously in the sensing range of the human infrared sensor 12 and the person is never far away, determining that an electrician never leaves the distribution box, and at the moment, not sending any instruction; if the analysis result shows that a person approaches in the sensing range of the human body infrared sensor 12 and a person moves away, a message to be processed is sent to the remote maintenance end 13, so that a manager of the remote maintenance end 13 carries out corresponding processing. Through timely discovery electrician leaves temporarily and sends the instruction of closing the block terminal chamber door, can avoid electrician work process to leave the potential safety hazard that forgets the block terminal chamber door caused briefly.

In order to ensure the smooth progress of various processing flows, the controller 11 may be configured with a stand-by independent power supply, and in the case of temporary power failure at the construction site, the independent power supply may ensure the normal operation of the controller 11, thereby improving the reliability of the controller 11.

In some alternative embodiments, the configuration information of the remote maintenance end 13 is generated by: the remote maintenance terminal 13 generates configuration information which allows electricians to open the distribution box door through identity information in a specified time period based on a preset work plan; or the remote maintenance terminal 13 generates configuration information for allowing an electrician to temporarily open the door of the distribution box through the identity information by receiving a temporary instruction of the manager.

Specifically, the manager of the remote maintenance terminal 13 can pre-write a working plan, and the designated electrician in the allowed time is authorized to open the distribution box needing to work through the access card; when temporary operation is needed, a manager can issue a temporary instruction allowed by work on the mobile phone, and the remote maintenance end 13 receives the temporary instruction to generate configuration information for allowing electricians to temporarily open the door of the distribution box through identity information, so that other personnel are prevented from opening the switch for illegal operation of the distribution box.

In some alternative embodiments, the switching mechanism 15 includes: a door closing automatic locking mechanism 151 and a power mechanism 152; the power mechanism 152 is mechanically connected with the door closing automatic locking mechanism 151; the power mechanism 152 is electrically connected with the controller 11; the power mechanism 152 is configured to receive an instruction to open or close the box door sent from the controller 11, and to drive the locking portion of the door closing automatic locking mechanism 151 to be unlocked to open the box door in a case where the instruction to open the box door is received.

It should be noted that the switch mechanism 15 of the door of the distribution box is designed to open and close the door of the distribution box, and is intended to ensure that only authorized personnel can access the electrical equipment in the box to improve safety.

In order to improve the safety, in this embodiment, the switch mechanism 15 includes a power mechanism 152, where the power mechanism 152 is independently provided with a PLC control unit that is matched with the power mechanism, and is electrically connected to the controller 11, so as to receive the instruction of the controller 11 and generate corresponding power to drive the door closing automatic locking mechanism 151 to perform a corresponding action.

Alternatively, since the power distribution box for construction site needs to have a certain mobility and flexibility, the size of the power mechanism 152 is limited in this embodiment, that is, the power mechanism 152 is a motor with a size smaller than a preset threshold, for example, the power mechanism 152 may be a small motor with relatively small power and relatively small volume, further, the size of the small motor may be set as follows: the motor with the center height of 300mm or less or the outer diameter of the armature core of 300mm or less has a power range of 25W to 100W.

In this embodiment, the power mechanism 152 is mechanically connected to the door closing automatic locking mechanism 151. In the case where the command received by the power mechanism 152 is a command to open the box door, the locking portion of the door closing automatic locking mechanism 151 can be driven to be unlocked to open the box door.

Specifically, the distribution box is opened and allowed, when a specified staff (i.e. electrician who obtains identity authorization) is allowed to open the distribution box remotely, and the card reader is identified correctly, the small motor drives the automatic door closing locking mechanism 151 to hook the distribution box door to open, and overhaul or operation power and power transmission stopping operation is performed.

In consideration of the complexity of the construction site, there may be a temporary power failure or other emergency, and at this time, in order to ensure safety, the power distribution box should be locked in time when an electrician temporarily leaves the power distribution box, so as to avoid danger caused by misoperation of non-professional personnel. Thus, in some alternative embodiments of the present application, the switching mechanism 15 further comprises: spring-loaded hydraulic buffer mechanism 153; the spring energy storage hydraulic buffer mechanism 153 is used for driving the automatic door closing and locking mechanism 151 to automatically close and lock the door of the distribution box through the cooperation of the spring energy storage and a hydraulic system.

In this embodiment, the spring energy storage hydraulic buffer mechanism 153 is used for controlling the closing of the box door of the distribution box and locking, and provides power for driving the closing of the box door of the distribution box through spring energy storage, and controls the movement speed of the box door of the distribution box through hydraulic buffer, so that the closing process of the box door is more stable. In addition, the device does not need power to provide driving force, can automatically close and lock, temporarily fails in a construction site, and can automatically lock the box door to prevent misoperation. By adopting the spring energy storage hydraulic buffer mechanism 153, the electrician can leave the automatic door closing. That is, the electrician forgets to close the door to leave after operating the switch, so as to avoid other irrelevant reasons, and the door of the distribution box immediately executes closing after detecting that the electrician leaves, thereby improving the safety.

Further, to facilitate operation by electricians, in some alternative embodiments, the apparatus further comprises: a work lock system 16; the work lock system 16 is electrically connected to the power mechanism 152, and the work lock system 16 maintains the power box door in a preset open position during construction using power provided by the power mechanism 152.

That is, when the identity information of the electrician satisfies the condition of allowing the opening of the box door and thus the opening of the box door, the box door can be locked at an arbitrary position by the work locking system 16 so as to perform the box operation.

Specifically, in some alternative embodiments, work lockout system 16 includes a position sensor 161, an electromagnet 162, and a fan mechanism 163; the position sensor 161 and the electromagnet 162 are respectively electrically connected with the power mechanism 152, and the electromagnet 162 is connected with the fan-shaped mechanism 163; a position sensor 161 for detecting a current open state of a door of the distribution box and transmitting the current open state to the controller 11; the controller 11 receives the current opening state and judges whether the distribution box door reaches a preset opening position according to the current opening state; if so, a start signal is sent to the power mechanism 152 to generate a current from the power mechanism 152 to the electromagnet 162; the electromagnet 162 generates a magnetic force by control of current to maintain the box door at a preset open position by the fan mechanism 163 during construction.

In this embodiment, when an electrician opens the door of the power distribution box, the fan-shaped mechanism 163 cooperates with the electromagnet 162 and the position sensor 161, the fan-shaped mechanism 163 is connected with the electromagnet 162 for maintaining the door in an open position, the electromagnet 162 is activated to lock the door when the door of the power distribution box reaches a preset open position, and the position sensor 161 is used for monitoring the punching state of the door and ensuring that the door can be safely locked in any position.

In some optional scenarios, a button for indicating the end of the work is further installed in the distribution box, the button is electrically connected with the controller 11, when the electrician finishes the work, the button can be actively touched, and the controller 11 can send out an instruction for driving the distribution box door to automatically close and lock.

In some alternative embodiments, the apparatus further comprises: the forced unlocking door opening mechanism 17 comprises an open lock, and the open lock is arranged at the bottom of the distribution box and used for forcibly opening the door of the distribution box when needed.

Through setting up the mechanism 17 that opens the door of forcing the unblock, can provide the operation of forcing the unblock when newly establishing the block terminal, perhaps when the power failure overhauls the block terminal and need force the unblock block terminal, force to open the block terminal chamber door, this mechanism also can regard as emergent use, as an emergent reserve scheme, under the unexpected circumstances, can open the chamber door of block terminal fast.

Specifically, the forced unlocking of the door opening mechanism 17 may be achieved by providing a lock at the bottom of the distribution box. Because the open lock is a relatively traditional lock type, the open lock is usually unlocked by using a physical key without involving electronics or digital technology, the electrical equipment in the box can be conveniently and quickly accessed by arranging the open lock at the bottom of the distribution box so as to carry out maintenance, overhaul or emergency treatment, and by using the physical key, an electrician can be authorized to easily open the open lock at the bottom of the distribution box without involving a complex electronic system.

In some alternative embodiments, the apparatus further comprises a signal acquisition module 18, the signal acquisition module 18 being in communication with the remote maintenance end 13; the signal acquisition module 18 is used for acquiring the state of the distribution box at the construction site and transmitting the state of the distribution box to the remote maintenance end 13; the remote maintenance terminal 13 is further configured to receive the status of the distribution box and display the status of the distribution box.

In this embodiment, the signal acquisition module 18 is configured to monitor and acquire the status of the electrical box at the construction site, wherein the status of the electrical box is a comprehensive reflection of various parameters and conditions inside and outside the electrical box. Parameters acquired by the signal acquisition module 18 may include: the operating state of the electrical system, the working condition of the electrical equipment, the environmental condition, the opening condition of the door of the distribution box, etc.
