In some examples, the wireless network unit is a WIFI-on-site unit. The mode of connecting each subsystem by the carrier communication unit and the low-voltage distribution line enables each subsystem to be electrically connected and simultaneously to carry out power carrier communication, is a connection mode integrating electrical connection and communication connection, and can avoid the cost expenditure and difficulty of additionally constructing a communication network. It should be noted that, instead of having to provide a low-voltage distribution line between every two subsystems, it is possible to: each subsystem is provided with a carrier communication unit, and an electric loop is formed among the subsystems through a low-voltage distribution line, so that a communication loop is formed among the subsystems. And networking communication is carried out through the on-site WIFI units, so that the network communication defects of low-voltage distribution line under abnormal conditions such as local power failure, short circuit and grounding are avoided, and the communication safety between the temporary power supply system and the temporary power supply system can be guaranteed.
Optionally, the carrier communication unit is configured to: and carrying out carrier communication by utilizing the working zero line and the protective earth wire of the high-frequency wave trap.

Further, the carrier communication unit is further configured to: if the working zero line is grounded in fault and the leakage protector is not tripped, the carrier communication between the phase line and the protective ground line is changed from the carrier communication between the working zero line and the protective ground line by utilizing the high-frequency wave trapper, so that the communication safety is improved.
The temporary power utilization system 100 in the construction site has strong anti-interference capability by adopting a distributed mode, the main power distribution management and safety management functions are completed by an on-site intelligent equipment layer, the dependence on a network communication layer is less, the burden of an intelligent management layer is lighter, and the requirements of real-time, rapidness and reliability of power distribution management and safety management can be better met. Further, the temporary power utilization system 100 in the construction site of the present invention is provided with the centralized intelligent management subsystem 130 and the remote management subsystem 120, and the centralized intelligent management subsystem 130 and the remote management subsystem 120 are combined to complete the comprehensive intelligent management function of the temporary power utilization system, so that the intelligent management of centralized remote measurement, remote signaling and remote control can be performed on the temporary power utilization in the construction site, and the real-time performance and the safety of the power utilization management can be improved.

The remote management subsystem 120, the centralized intelligent management subsystem 130 and the image monitoring subsystem 140 are connected in communication through a wireless network unit. It should be noted that, because the image monitoring subsystem 140 needs to be flexibly arranged according to the field situation, and the power access of the image monitoring subsystem can use a fixed or mobile power source, so that the carrier communication unit has a range limitation, the image monitoring subsystem 140 and other subsystems simultaneously adopt a carrier communication unit and a wireless network unit for communication.
As an alternative embodiment, multiple sets of image monitoring subsystems 140 are respectively disposed at multiple key monitoring points. The key monitoring point is a monitoring point capable of monitoring important local areas or important power distribution equipment of the temporary power utilization system.

Because the external loads are various in types and different in complexity, some external loads are provided with control systems, and the control systems are in hard connection and communication connection with the box system according to the actual conditions of the load systems, so that the purposes of safe operation and operation are achieved together. In addition, the box can be provided with a control system, and a control program is downloaded through system communication connection according to load requirements, so that the switch box self-provided control system is adaptive to different loads, and different control requirements and safe operation of different construction loads on a construction site are met.

When the process goes through the safety node, whether the component corresponding to the safety node is in a preset safety state or not is judged, and if the component is not in the safety state, safety prompt is carried out and/or the component is automatically changed into the safety state. For example: the disconnection of the connection is an important key point when the earth leakage protector and the knife switch are disconnected, and the node is confirmed to be safe to carry out the next step.
The database storage module is used for storing at least some of the collection processing results of the data collection processing module.
The data output module is configured to output at least some of the collection processing results of the data collection processing module, for example, the collection processing results are correspondingly output to at least one box intelligent subsystem and/or the remote management subsystem 120.
In some embodiments of the invention, the control module of the intelligent subsystem of the enclosure includes a receiving unit and an intelligent management unit.
The receiving unit is used for receiving identity information, and/or power distribution safety information, and/or a remote identity authorization result sent by the remote management subsystem 120, and/or a remote process confirmation signal sent by the remote management subsystem 120.
The intelligent management unit is used for allowing and assisting an operator with a first authority to perform a first process, or allowing and assisting an operator with a second authority to perform a second process, or controlling the access control module to automatically lock and control the safety warning module to prompt a locking reason according to the identity information and/or the remote identity authorization result and/or the remote process confirmation signal and/or the power distribution safety information. The first process only comprises some simple processes which can be executed by personnel with lower professional level, and specifically comprises a general operation process, a box body power-off process, a wire connecting and disconnecting process and a leakage protector reclosing process; the second process includes a service process. Thus, the aforementioned allowance of the first process may also be considered as placing the box intelligence subsystem in an operational and disconnect mode, and the aforementioned allowance of the second process may also be considered as placing the box intelligence subsystem in a service mode. The second right is ranked higher than the first right. The first process and the second process are two processes for solving the temporary electricity problem corresponding to different professional technical level personnel, and are determined by the characteristics of the temporary electricity system. The operation and connection and disconnection mode (or the first process) is a safe operation mode aiming at general operators (operators with lower professional level) of the electric equipment for field construction, and is suitable for switch boxes and distribution boxes. The overhaul mode (or second process) is a safe operation mode for professional electricians (operators with higher professional levels) and is applicable to a main distribution box, a distribution box and a switch box.
It should be noted that the process of processing by the intelligent management unit according to the identity information is a system authorization mode, and authorization is performed according to preset information of a system program; the process of processing by the intelligent management unit according to the remote identity authorization result is a manual authorization mode, and authorization is performed after the security state is confirmed by the remote terminal. Specifically, in some embodiments where the processing is performed according to identity information, the persons are classified into at least two levels according to the identity information in advance: and allowing a person who performs the operation of the first process to be a person with a first authority (for example, a constructor) and a person who performs the operation of the second process (for example, a professional electrician) to be a person with a second authority, and recording the pre-authorization result in the system so that the intelligent management unit determines the authority of the operator according to the identity information of the operator collected in real time. Alternatively, the persons may be classified into at least three levels in advance: a person having a first authority, a person having a second authority, and a person not permitted to perform an operation. In some embodiments, the remote identity authorization result is a manual authorization signal sent by a manager (e.g., a professional electrician) through the remote management subsystem 120, and the remote identity authorization result is processed according to the remote identity authorization result of the remote management subsystem 120, including allowing the first process, allowing the second process, and not allowing the first process. Optionally, in some embodiments, the administrator is the aforementioned person with the second authority, that is, the person with the second authority also has the authority to perform management actions such as manual authorization and the like by using the remote management subsystem 120.
In some examples, the control module further includes a temporary storage unit for temporarily storing a portion of data (e.g., a warning statement) transmitted to the temporary storage unit from the box storage module of the box intelligence subsystem or from the database storage module of the centralized intelligence management subsystem 130 after the control module is initialized. After a power loss, the temporarily stored data is lost.
Since the electrical equipment carried by the box body in the construction site is not fixed, the earth leakage protector in the box body can be tripped for various reasons, and the operators on duty can not completely deal with the situations. According to the construction site temporary power utilization system 100, by allowing and assisting an operator with a first authority to perform a first process including a connection and disconnection process and a leakage protector reclosing process or allowing and assisting an operator with a second authority to perform a second process including an overhaul process, simple work such as connection and disconnection, leakage protector reclosing and the like can be performed by trained operators with the first authority under the condition that safety is ensured, safety of temporary power utilization on a construction site can be improved, management, process maintenance and timely monitoring are facilitated, and process efficiency can be improved.

The second intelligent management subunit is configured to: and allowing an operator with corresponding authority to perform a second process, prompting system information and/or correct operation steps and/or dangerous conditions in the second process, and performing safety node and process confirmation in the second process.
In some embodiments of the present invention, corresponding to the embodiments shown in fig. 3 and 4, the first process (i.e., the operation and disconnect mode) corresponding to the distribution box intelligence subsystem 112 is different from the first process corresponding to the switch box intelligence subsystem 113: the first process for the intelligent distribution box subsystem 112 is performed under the dual process confirmation of the intelligent distribution box subsystem 112 and the manager using the remote management subsystem 120. Specifically, in some embodiments, the receiving unit of the electrical distribution box intelligence subsystem 112 is to: receiving identity information, power distribution security information, a remote identity authorization result sent by the remote management subsystem 120 and a remote process confirmation signal sent by the remote management subsystem 120; the first intelligent management subunit of the electrical distribution box intelligent subsystem 112 is specifically configured to: according to the remote process confirmation signal, an operator with corresponding authority is allowed and assisted to carry out the box power-off process and the wire connection and disconnection process, and safety node and process confirmation in the first process is carried out.
In some embodiments of the present invention, the first intelligent management subunit of the box intelligence subsystem is specifically configured to: judging according to the loop live information and the loop locking information; if the loop of the box body has load current (namely, the loop electrified information is yes, indicating that a load is running), or the loop of the box body is in a locking state (namely, the loop locking information is yes, unlocking is not allowed), or the box body is provided with running electric equipment, controlling the electromagnetic door lock to keep the locking state, starting the safety warning module to prompt the locking reason, and not allowing an operator to open the box for operation or connect and disconnect lines; if the loop of the box body does not have load current, the loop of the box body is in an unlocked state, and the box body does not have running electric equipment, a door lock opening signal is sent to the access control module to control the electromagnetic door lock to be automatically opened in a time-limited mode, and the intelligent subsystem of the box body enters an operation mode to allow the leakage protector and/or the disconnecting link switch to be opened and closed. In some examples, the earth leakage protector and the disconnecting switch are provided in a switch box and a distribution box, and the disconnecting switch is provided in a main distribution box. It should be noted that, depending on the specific scale of the temporary power installation, the leakage protector may be replaced by a low-voltage circuit breaker. Optionally, the earth leakage protector can be reclosed after prompt confirmation in the step.
Further, the first process comprises a box power-off process before connecting and disconnecting, and the power-off sequence is as follows: the earth leakage protector is disconnected first, and then the knife switch is disconnected. Specifically, the first intelligent management subunit of the intelligent subsystem of the box is further configured to: when the electromagnetic door lock is unlocked, sending power-off operation prompt information to the safety warning module according to the opening and closing information of the leakage protector, the position information of the disconnecting switch or the electrified information of a disconnecting switch outgoing line terminal (or called as a lower terminal) acquired by the acquisition module so as to control the safety warning module to prompt correct power-off operation, for example, prompting the rule of the next safety operation by voice; and judging whether the power-off sequence of the leakage protector and the disconnecting link switch is wrong or not, and if the power-off sequence of the leakage protector and the disconnecting link switch is wrong, sending danger warning information to the safety warning module to control the safety warning module to prompt dangerous conditions. It should be noted that, in practice, only one of the knife switch position information and the knife switch outlet terminal live information needs to be acquired and used to perform corresponding processing.
Further, the first process comprises a wire connecting and disconnecting process, wherein the wire connecting and disconnecting process is carried out when the terminal is not electrified and the leakage protector and the disconnecting switch are in an off state. Specifically, the first intelligent management subunit of the intelligent subsystem of the box is further configured to: when the electromagnetic door lock is opened, whether an outgoing cable connection and disconnection area (or called as a lower connection and disconnection area) in the box body is touched or not is judged according to a signal of the safety sensor, and if the outgoing cable connection and disconnection area is touched, the following steps are carried out: judging according to the on-off information of the leakage protector, the position information of the disconnecting switch or the electrification information of the outgoing line terminal of the disconnecting switch, which is acquired by the acquisition module; if the whole box body or a loop of a touched area is in an uncharged state, namely the corresponding leakage protector is disconnected (or called as a tripping state), and the position of the disconnecting switch is disconnected or the position of a disconnecting switch outgoing line terminal is in an uncharged state, the intelligent subsystem of the box body enters a connecting and disconnecting mode, allows the operation of connecting and disconnecting, and sends connecting and disconnecting prompt information to the safety warning module to control the safety warning module to prompt a correct connecting and disconnecting process; if the whole box body or a loop of a touched area is in a charged state, namely the leakage protector is in a closed state (or called as an un-tripped state), or the position of the disconnecting link switch is in a closed state or the outlet terminal of the disconnecting link switch is in a charged state, dangerous warning information is sent to the safety warning module to control the safety warning module to prompt dangerous conditions.

It should be noted that, when the disconnecting switch is in the off state, although the outlet terminal of the disconnecting switch is not charged, the inlet terminal of the disconnecting switch (actually, the inlet cable connection and disconnection area of the box body) is still charged, and it is necessary to provide a safety sensor at the inlet terminal and control the safety warning module to prompt when the control module receives a signal of the safety sensor, so as to prevent people or foreign matters from approaching the inlet terminal. In addition, besides the existing single-loop switch box on the site, the construction site also has a plurality of integrated distribution boxes, such as lighting boxes, the interior of the integrated distribution box is not a loop, and the integrated distribution box also has a plurality of relatively complex devices, and the matched terminal distribution box is provided with a plurality of loops, so that the warning is carried out under the condition that adjacent electrified loops exist, and the safety can be improved. In addition, under the condition that one loop is in wiring operation, a charged area and an uncharged area exist, and the safety can be improved by warning when the loop possibly touches the charged area.
In some embodiments of the invention, the first intelligent management subunit is further configured to: if the power-off sequence of the leakage protector and the disconnecting link switch is wrong, or if the whole box body or a loop in a touched area is in a charged state, or if an incoming cable connecting and disconnecting area of the box body is touched, or if a charged loop is arranged in the box body, or if the loop in the box body has a charged area, the power distribution parameter information and/or power distribution safety information of the box is sent to the remote management subsystem 120, and/or the centralized intelligent management subsystem 130 is informed to send the power distribution parameter information and/or power distribution safety information and/or statistical information of a plurality of boxes to the remote management subsystem 120, and/or the image monitoring subsystem 140 is informed to send the collected images of the real-time operation conditions to the remote management subsystem 120, so that the manager can use the remote management subsystem 120 to know the real-time operation condition of the operator for remote process confirmation; receive a remote procedure confirmation signal sent by the remote management subsystem 120; and according to the remote process confirmation signal, if the result of the remote process confirmation is confirmation, allowing the operation of connecting and disconnecting, and sending a connecting and disconnecting prompt message to the safety warning module to control the safety warning module to prompt a correct connecting and disconnecting process.

In some embodiments of the invention, the second process comprises a service process. Specifically, the collection module of the box intelligence subsystem further includes a centralized information receiving unit for receiving at least some of the collection processing results of the centralized intelligence management subsystem 130.
