It is also called watt-hour meter, fire meter, electric energy meter, kilowatt-hour meter, which refers to an instrument for measuring various electrical quantities.

[0003] With the development of the electric meter industry, in order to better and more timely understand the electricity consumption in the area, an electric meter electric variable data collector will be installed on the electric meter box, and then the electric meter electric variable data collector will be used to collect and monitor the electric meter electric variable data, so as to facilitate understanding of residents' electricity consumption.

[0004] At present, the electric variable data acquisition monitor of the electric meter is generally installed inside the electric meter box together with the electric meter. The data acquisition monitor is connected to the electric meter through wires using a wiring device. Common wiring devices are mostly metal bolts that fix the wires for wiring. After the data acquisition monitor is installed in the electric meter box, it is necessary to rewire during the circuit maintenance process. Since the internal operating space of the electric meter box is small and separate power connection cannot be performed, the wiring operation is inconvenient. At the same time, in the actual transmission of the electric variable data of the electric meter, when the electric variable data of a certain electric meter suddenly surges, due to the limited transmission capacity of the transmission module, the frequent transmission of a large amount of electric variable data of the electric meter is likely to affect the normal transmission of the electric variable data of other electric meters.

[0058] By pre-connecting the electric wire with the separate wiring mechanism, and then stably connecting the separate wiring mechanism with the base station, and using the separate wiring mechanism to contact the wiring female end, power is turned on. By using the wiring device, the electric wire can be fixed without disassembling the data acquisition monitor, and there is no need to extend one hand into a narrow operating space to fix the electric wire, and then locked with screws, which improves the convenience of power connection. Subsequently, the electric variable data of the electric meter can be collected by the collection module, and then the electric variable data of the electric meter can be processed by the electric variable data testing module, and then the electric variable data of the electric meter can be transmitted by the transmission module. When the data of one of the electric meters is too much, the transmission mode can be switched based on the transmission mode switching model, thereby temporarily delaying the transmission frequency, thereby avoiding affecting the normal transmission of the electric variable data of other electric meters;

[0059] After the connecting cylinder and the bearing cylinder are plugged together, a screwdriver can be inserted into the cross-shaped groove, and the screwdriver can be used to further drive the connecting cylinder to move. Then, when it is necessary to clamp, the fixed round block and the connecting cylinder will not rotate due to the mutual limitation of the limit block and the limit groove. The fixed round block can be driven to rotate by rotating the screwdriver, thereby realizing the rotation of the clamping column. The screwdriver can be used to replace the manual hand to reach into the narrow operating space, so as to facilitate the connection of electricity.

[0060] By arranging the bearing cylinder, the connecting cylinder and the spring assembly, the bearing cylinder facilitates the docking of the connecting cylinder with the connecting groove. At the same time, the connecting sleeve is moved downward at a later stage, and then the connecting sleeve is twisted, so that the clamping column comes out from the inside of the U-shaped groove, and the spring is pushed to reset, driving the bearing cylinder and its connecting cylinder to reset together, thereby facilitating the removal of the connecting cylinder.

[0084] Example 3 further discloses a transmission mode switching model based on Example 2. The specific content of the transmission mode switching model is as follows: switching is performed by setting a three-level step transmission mode, and the three-level step transmission mode is divided into: a first-step transmission mode, in which the transmission module transmits the meter electric variable data at intervals of each Tα time period; a second-step transmission mode, in which the transmission module transmits the meter electric variable data at intervals of each Tβ time period; a third-step transmission mode, in which the transmission module transmits the meter electric variable data at intervals of each Tγ time period; wherein Tγ is greater than Tβ is greater than Tα; the switching threshold of the switching transmission mode is set to X, and the meter electric variable data transmitted in the Tα, Tβ or Tγ time period is recorded as Y, and the first-step transmission mode The transmission value is recorded as A, and the calculation formula of A is: A=Y / Tα. The transmission value of the second-step transmission mode is recorded as B, and the calculation formula of B is: B=Y / Tβ*1.2. The transmission value of the third-step transmission module is recorded as C, and the calculation formula of C is: C=Y / Tγ*1.4. When A is greater than or equal to X, the first-step transmission mode switches to the second-step transmission mode. When A is less than X, the first-step transmission mode is maintained. When B is greater than or equal to X*1.2, the second-step transmission mode switches to the third-step transmission mode. When B is less than X*0.8, the second-step transmission mode switches to the first-step transmission mode. When B is greater than X*0.8 and less than X*1.2, the second-step transmission mode is maintained. When When C is greater than or equal to X*0.8, the third-step transmission mode is maintained. When C is less than X*0.8, the third-step transmission mode is switched to the second-step transmission mode. When the transmission module starts to transmit the meter electric variable data, the transmission mode is in the first-step transmission mode, that is, the transmission module transmits the meter electric variable data once every Tα time period. When the meter electric variable data of a certain meter surges within the Tα time period, the calculation formula of the transmission value A of the first-step transmission mode is: A=Y / Tα. When A is greater than or equal to X, the first-step transmission mode is switched to the second-step transmission mode. When A is less than X, the first-step transmission mode is maintained. When switching to the second-step transmission mode, each time the Tβ time period is interval , the transmission module transmits the meter electric variable data once. At this time, the calculation formula of the transmission value B of the second step transmission mode is: B=Y / Tβ*1.2. When B is greater than or equal to X*1.2, the second step transmission mode switches to the third step transmission mode. When B is less than X*0.8, the second step transmission mode switches to the first step transmission mode. When B is greater than X*0.8 and less than X*1.2, the second step transmission mode is maintained. When switching to the third step transmission mode, the transmission module transmits the meter electric variable data once every Tγ time period. When C is greater than or equal to X*0.8, the third step transmission mode is maintained. When C is less than X*0.8, the third step transmission mode is switched to the second step transmission mode.
