Background technique

In the daily life of modern people, electricity has become one of the indispensable main energy sources. In order to calculate the electricity consumption of users, the power company generally installs mechanical meters near the users. Mechanical meters are A metering instrument that allows current to pass through and records the amount of current passed. As the basis for charging by the power company, the power company connects the power supply line to a mechanical meter, and then leads the wire from the other end of the mechanical meter to the mains of the power user. The switch further distributes the power to household appliances and sockets. When the electricity user uses the power, the current passes through the coil in the mechanical meter to drive the gear to rotate, which in turn drives the pointer of the counter to rotate, indicating the current cumulative electricity consumption; On the other hand, the power company will continuously send meter readers to record the cumulative electricity consumption on the mechanical meter at intervals of a predetermined time (such as two months), and subtract the previous (two Months ago), the degree difference value obtained from the cumulative electricity consumption is the electricity consumption of the electricity user within the predetermined time, and the power company can then substitute the electricity consumption of the electricity user into an electricity price calculation formula to calculate The electricity fee that should be paid by the electricity user.

However, in order to save electricity bills or increase electricity consumption, some unscrupulous electricity users often use special tools to dismantle mechanical meters by illegal means and steal electricity (such as dialing back counters, replacing mechanical meters, etc.) In order to slow down the gear speed of the mechanical meter, put steel nails, coils or magnets in the mechanical structure of the mechanical meter to interfere with the rotation of the gears in the mechanical meter, so that the cumulative electricity consumption displayed by the counter The degree is less than the actual power consumption, or the circuit is modified, and the power is directed to the electrical appliance that the user wants to use by connecting another wire), so as to cause an error between the actual power consumption and the accumulated power consumption, and then seek Illegal interests, this will not only cause leakage of electricity from the mechanical meter, increase the risk of electric shocks due to accidental touches by others, but also cause huge losses to the power company, and even cause the mechanical meter to exceed the load and cause a short circuit, which will cause fire or electrical appliances. damage and cause serious harm to public safety.

In view of this, in order to solve the shortcomings of the mechanical structure of traditional mechanical meters that are easy to be disassembled and modified, digital meters have emerged as the times require; since digital meters have built-in detection chips and digital displays, they can be detected when abnormal conditions occur. (for example: the case of the digital meter is disassembled, or there is an abnormally large current passing through, etc.), the detected abnormal situation information and light signals will be displayed on the digital display screen, so that the meter readers of the power company can pass through Watch the digital display to detect abnormal situations in time, and perform follow-up inspection and maintenance on the digital meter; because the digital meter does not drive the gear and pointer to rotate through the current, but the processing chip detects and calculates the electricity consumption of the user. Moreover, the digital meter does not have a mechanical structure, so it is not easy to be cracked by the traditional electricity stealing technology, so it can effectively prevent electricity theft, gradually replace the mechanical meter, and is widely accepted by the public.

However, general digital ammeters are installed far away from the living space of electricity users (such as: the basement or stairwell of buildings or apartments), so electricity users cannot know the current electricity consumption situation at any time, and it is easy to overuse electricity, causing electricity users to fall into the dilemma of having to pay high electricity bills. In addition, since large-scale electricity users generally have contracted capacity with power companies, they cannot know the current electricity consumption situation at any time. If the amount of electricity exceeds the capacity of the electricity contract, the power company will impose a huge fine for exceeding the contract, which will cause serious troubles to the electricity users, and is not liked by the electricity users.

In addition, because the general large-scale power users (such as: factories) have established power contract capacity with the power company, in order to avoid their own power consumption exceeding the power contract capacity, the power company imposes a huge penalty for exceeding the contract power consumption Generally, large-scale power users often install another meter on the power supply line between the digital meter and a power switch in the factory (because the current power consumption situation cannot be known at any time, so the general large-scale power users will be in the vicinity of other meters) Install the other meter at the location of the factory to roughly estimate the current electricity consumption), so that the general large-scale power users can estimate the maximum demand value of the factory electricity by themselves by looking at the other meter (that is, the maximum power consumption electricity) and payable electricity charges as the basis for factory electricity management; however, since the other meter must be directly connected to the power supply line of the factory, it is often damaged due to poor construction technology or old lines. As a result, the electricity consumption measured by the other meter is very different from the data displayed by the digital meter of the power company; moreover, the other meter cannot measure the time displayed by the digital meter of the power company, so generally Large-scale power users have no way of knowing the actual time of the power company displayed by the digital meter, which leads to large-scale power users making great errors when judging the time point of the maximum demand value (that is, the maximum power consumption) of the factory. And the specifications of another meter used by different large-scale power users are different (such as: meter head, current comparator and voltage comparator, etc.), so the electricity consumption measured by the different another meter is not consistent with the figure of the power company. The data displayed by the electricity meter is very different, which will cause great troubles for general large-scale power users, and make it impossible for general large-scale power users to accurately know the current electricity consumption situation, let alone estimate the electricity bills that should be paid, resulting in their own electricity consumption. If the power consumption exceeds the capacity of the electricity contract, the power company imposes a huge fine for exceeding the contract; in addition, since the other meter must be directly connected to the power supply line of the factory, it is also easy to be damaged due to poor construction technology or wiring. It is old and damaged, which causes the temperature of the other ammeter to continue to rise, which is easy to generate sparks, and even leads to the danger of fire, which causes irreparable regrets.

Based on the above, in order to avoid the electricity consumption exceeding the electricity contract capacity, and the power company imposes a huge fine for exceeding the contract, generally large-scale electricity users still use a predetermined time interval (such as: hourly or Every 24 hours) to send someone to the location of the digital ammeter to copy the accumulated electricity consumption on the digital ammeter, and calculate the electricity fee that should be paid according to the accumulated electricity consumption, as the basis for the factory's electricity management; however, due to general The factories of large power users are often located in remote mountainous areas or industrial areas, and their digital meters are often concentrated near the high-voltage power towers to facilitate the meter readers of the power company to copy the accumulated electricity consumption on the digital meters. Therefore, in In remote mountainous areas or industrial areas with poor weather conditions (such as mountain showers, dense fog, typhoons or lightning strikes), it often threatens the personal safety of meter readers dispatched by power companies or large power users (such as: due to rain fall due to slippery roads, lost direction due to dense fog, fall off a cliff due to typhoon, or be struck by lightning, etc.), causing serious troubles to power companies or large power users.

To sum up, it can be known how to design an innovative remote monitoring system for a digital electric meter, which not only has a digital electric meter, a camera and a main processor, but also allows the camera to capture the image of the digital display screen of the digital electric meter , to generate an image data, and transmit the image data to the main processor in a wired or wireless manner, so that the main processor analyzes the image data and recognizes the corresponding time and related state information displayed by the digital electric meter After generating identification data, the identification data can be transmitted and displayed on the display screen of the main processor in real time, so that the power user can watch the identification data displayed on the display screen at any time, Furthermore, the purpose of real-time monitoring of the current electricity consumption is achieved, and the time displayed on the display screen is synchronized with the time displayed by the digital ammeter, and the analysis data generated by the identification data is analyzed in real time through the remote monitoring system, According to synchronously control the power supply of a power switch (continuous or stop power supply), and then enable the remote monitoring system to accurately calculate and control the power demand of the power user, so as to automatically manage and adjust the power consumption status of the power user, And to achieve the purpose of automatic meter reading, and the user does not need to install another ammeter in addition, and then can avoid the danger of fire, which is an important subject that the utility model wants to explore here, so, it will be more important to the electric power The safety of meter readers dispatched by companies or large power users is of great help, and it is also of great help to energy management and energy conservation.
