Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a management and control system for a temporary grounding wire comprises a management and control host, an in-place monitoring system and a positioning alarm device.
The on-site monitoring system comprises a grounding wire on-site monitoring point, a controller, an alarm, a GSM (global system for mobile communications) short message controller and a management and control host, wherein the grounding wire on-site monitoring point is responsible for monitoring whether the grounding wire is on site or not and uploading monitoring data to the controller and the management and control host, the controller receives and processes data uploaded by the grounding wire on-site monitoring point and sends an instruction to the alarm and the GSM short message controller, specifically, the grounding wire on-site monitoring point uploads the monitoring data to the management and control host through a GMS (gateway mobile switching system) network, and the management and control host acquires, manages, inquires, statistically analyzes and prints the grounding wire on-site data through management and control software.
When the grounding wire is not lent, when the grounding wire cannot be detected to exist at the site monitoring point, the alarm gives out audible and visual alarm, and the GSM short message controller sends a short message to a specified mobile phone; the borrowing time of the ground wire can be set to count down, and if the borrowing time is not returned in time, a signal is sent to the alarm and the GSM short message controller to give an alarm.
The positioning alarm device is installed on the grounding wire through a buckle and comprises a GPS (global positioning system) positioner, an audible and visual alarm and a remote control trigger, the GPS positioner is used for positioning and sending position information of the grounding wire to the mobile terminal, the position of the grounding wire can be positioned in real time by a worker through the mobile terminal, the remote control trigger is communicated with the audible and visual alarm through a wireless signal, and the remote control trigger can remotely start or stop alarming of the audible and visual alarm.
The audible and visual alarm comprises a wireless receiving and transmitting module A, a microcontroller A and an audible and visual prompting module, and the remote control trigger comprises a wireless receiving and transmitting module B, a microcontroller B, a key scanning module and a luminous prompting module. After scanning a key on a microcontroller B on the remote control trigger, sending a command code to a wireless transceiver module B, judging whether a channel is clean by the wireless transceiver module B, immediately carrying out forward error correction and whitening treatment on the command code if the channel is clean, carrying out CRC calculation, packaging and modulating the command code into a radio frequency signal to send out; after receiving the wireless signal sent by the remote control trigger, the wireless transceiver module A on the audible and visual alarm demodulates the radio frequency signal into a baseband signal and then demodulates the baseband signal into a digital signal, the microcontroller A calculates the CRC value of the received signal and compares the CRC value with the CRC value sent by the remote control trigger, if the CRC values are not equal, the data is wrong, the data is discarded, and if the CRC values are equal, whitening removal and error correction calculation are carried out, so that the correctness of the received signal is ensured. The microcontroller on the audible and visual alarm starts or stops audible and visual alarm according to the command code sent by the remote control trigger. During the audible and visual alarm period, a wireless signal is transmitted back to the remote control trigger, and the remote control trigger also gives out light for prompting, so that the audible and visual alarm of the alarm cannot be heard and seen when the distance is long is prevented.
Specifically, the management and control host is internally provided with a leakage protector.
The leakage protector, called leakage breaker for short, is mainly used for protecting the human body with fatal danger from electric shock when the equipment has leakage fault, has the functions of overload and short circuit protection, can be used for protecting the overload and short circuit of a circuit or a motor, and can also be used for the infrequent switching starting of the circuit under the normal condition.
The earth leakage protection relay is an earth leakage protection device having a function of detecting and judging a leakage current, but not a function of turning off and on a main circuit. The leakage protection relay consists of a zero sequence mutual inductor, a release and an auxiliary contact for outputting signals. When the main circuit has leakage current, the auxiliary contact and the separating release of the main circuit switch are connected in series to form a circuit, so that the auxiliary contact switches on the separating release to disconnect the air switch, the AC contactor and the like, so as to break the brake and cut off the main circuit. The auxiliary contact can also be connected with an acoustic and optical signal device to send out a leakage alarm signal to reflect the insulation condition of the circuit.
The earth leakage protection switch is a switching element which can not only turn on or off a main circuit as in other circuit breakers, but also has a function of detecting and judging leakage current, and when leakage or insulation breakdown occurs in the main circuit, the earth leakage protection switch can turn on or off the main circuit according to the judgment result. It can be matched with fuse and thermal relay to form a low-voltage switch element with complete function.
The leakage protection socket is a power socket which can detect and judge leakage current and cut off a loop. The rated current of the device is generally below 20A, the leakage action current is 6-30 mA, the sensitivity is high, and the device is commonly used for protecting hand-held electric tools and mobile electrical equipment and civil places such as families and schools.
The leakage protector adopts a leakage protection switch which is most widely applied according to requirements.
This patent monitoring system in place still includes electromagnetic lock device, and electromagnetic lock device sets up at the earth connection mounted position, and monitoring system in place's management and control host computer passes through the locking and the opening of wireless network control electromagnetic lock device to the earth connection, realizes that long-range authorized personnel operate the earth connection, prevents to appear the phenomenon of mistake string mistake tear open.
The scientific management and control of earth connection has been strengthened to this patent, effectively prevent losing and stolen of earth connection, the earth connection plays the warning operation in the use, all kinds of operation personnel such as maintenance do not leak the effect of tearing open the earth connection before the power transmission, it does not change and weakens any security performance of current earth connection, do not change current all kinds of operation system and standard yet and be to the replenishment and the improvement of current "people's air defense" and "technical prevention" measure, the problem of the pernicious maloperation accident of closing a floodgate according to the earth connection takes place to solve, and is simple and practical, and has very strong security benefits and social.
