Problems solved by technology

On the one hand, power theft has caused huge economic losses to the power management department, and the normal order of power supply and consumption has been disrupted. Improper live operation has even caused fires, damage to power supply equipment, and even caused large-scale power outages in the power system. have a serious impact on social stability
The meter’s statistical electricity consumption is equal to the product of the voltage applied to the voltage coil, the current flowing through the current coil, and the power factor and time. Any change in any parameter can change the electric energy, thereby achieving the purpose of stealing electricity. Therefore, the electricity stealing method There are many kinds, which bring great difficulties to prevent electricity theft
[0004] At present, most of the perpetrators of stealing electricity are specialized electricians. They are familiar with the working principle and wiring methods of electric energy meters. In addition, the sealed wires can be easily bought in the market, and they are not easy to be found.
If special anti-stealing equipment and instruments are used, it will not only interfere with energy metering and increase system costs, but most importantly, the image evidence of the electricity theft scene cannot be obtained. Therefore, it is necessary to provide a smart meter box with a monitoring system very necessary

Embodiment 1

[0031] Embodiment 1: smart meter box, such as Figure 1-Figure 3As shown, it includes a box body 1 and a box cover 2 hinged on the box body 1. The box cover 2 is transparent, which is convenient for personnel to observe the electric meter in the box body 1 through the box cover 2. The box cover 2 is connected to the box body 1 through a lock. phase fixed. The box body 1 is provided with a controller module, a camera module 3 connected to the controller module through a line, a communication module connected to the controller module, a control unit 5 arranged in parallel with the camera module 3, a power supply module 4 for power supply, The controller module includes a single-chip microcomputer, and the communication module is a wireless data communication module, which is used to transmit information such as short messages and images. The power supply module 4 includes a secondary conversion transformer and a spare lithium battery. convert. The camera module 3 is an infrare...

Embodiment 2

[0033] Embodiment 2: smart meter box, including embodiment 1, the raw material of casing 1 in embodiment 1 comprises the following components, by weight, 35 parts of PC, 50 parts of PBT, 30 parts of glass fiber, 8 parts of glucose barium acid, 8 parts of bis-hydroxyethyltrimethylolmethylamine, 3 parts of flame retardant, 3 parts of POE-g-MAH, and 1 part of silane coupling agent. The flame retardant is mica powder.

[0034] The preparation method of box 1 is as follows: dry PC and PBT in a high-temperature blast drying oven, add each component in the raw material into a high-speed mixer and mix evenly, and then use a twin-screw extruder to blend and extrude to granulate. The blending temperature is 230°C-245°C, and the parameters of the twin-screw extruder are as follows: screw diameter 35mm, motor power 18.5 / 30Kw. The extruded strips are cooled by tap water and air, pelletized by a pelletizer, and then molded into products by a plastic injection molding machine.

Embodiment 3

[0035] Embodiment 3: The difference between the smart meter box and Example 2 is that the raw material of the box body 1 includes the following components, in parts by weight, 42 parts of PC, 44 parts of PBT, 25 parts of glass fiber, 5 parts of barium gluconate , 3 parts of bis-hydroxyethyltrimethylolmethylamine, 6 parts of flame retardant, 5 parts of POE-g-MAH, 3 parts of silane coupling agent. The flame retardant is mica powder.

Abstract

The invention relates to the technical field of electric equipment, and discloses a smart electric meter box. The smart electric meter box comprises a box body, a box cover, a controller module, a camera module, a communication module, a power supply module and a control part, wherein the box cover is hinged to the box body; the controller module is arranged in the box body; the camera module is connected with the controller module; the communication module is connected with the controller module; and the control part is connected in parallel with the camera module. The smart electric meter box has the advantages and beneficial effects that the camera module is arranged in the box body of the smart electric meter box, the camera module is started and acquires an image after a power theft forcibly opens the box cover, and the controller module controls the communication module to transmit the image to a smart electric meter box administrator, thereby facilitating remote management, monitoring and prevention of power stealing. The box body is made of thermoplastic plastic prepared by co-blending PC / PBT and the like, so that the mechanical performance can meet the requirement. The thermoplastic plastic can be recycled after use, so that harm to the environment is lowered, and the effects of remote management, monitoring, prevention of power stealing and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an intelligent electric meter box. Background technique [0002] The traditional electricity billing model in our country is to use manual meter reading, then input it into the computer, calculate the electricity consumption and then charge. In order to pursue the goal of more efficient power supply requirements, the traditional model has deviated from the current development trend of intelligence, modernization and automation in residential quarters. There are millions of power users in large and medium-sized cities and industrial cities, and now not only in our country , all of which are equipped with an electric meter for each user. If you continue to send manual meter reading regularly, a lot of manpower, financial and material resources will be wasted, and the traditional method is troublesome to operate, especially easy to copy wrong data or miss some users. M...
