Embodiment Construction

[0028] A structure of the capacitive remote counter reading device of the present invention is to make a movement similar to a word wheel counter, such as figure 1 As shown, it is a five-digit decimal character wheel counter reading device, which is assembled from a core shell 6, a character wheel counting wheel 1, a transmission gear 9 and a circular capacitance sensor 2. The five character wheel counting wheels 1 are horizontally arranged on the same horizontal axis, and the gear sets composed of five sets of transmission gears 9 are respectively meshed with each character wheel counting wheel 1. The special structure of the gear sets realizes that the character wheel counting wheels 1 Intermittent rotation of the decimal system; there are four circular capacitance grid sensors 2, which are respectively installed on the side of the rear four-character wheel type counting wheel 1. The circular capacitance grid sensor 2 adopts a coupled moving grid plate 2-1 and a fixed grid pl...

Abstract

The invention relates to a capacitance-grid remote counter reading device which comprises a multistage counting wheel and sensor devices for detecting rotating angles of the counting wheels, wherein the multistage counting wheel is driven by a gear group; the sensor devices correspond to the counting wheel at each stage or an appointed stage; the sensor devices are circular capacitance-grid sensors with absolute measurement functions, and each circular capacitance-grid sensor is connected to a dedicated large-scale integrated circuit by a corresponding conversion switch; and the capacitance-grid sensors can adopt a double-piece reflection type structure or a three-piece transmission type structure. The multistage counting wheel can be designed into a continuous rotating form, and the counter reading device is suitable for reading data of a pointer type water meter; and the multistage counting wheel can be also designed into an interval rotating form so as to be conveniently installed in counting devices, such as water meters, electric meters, gas meters, and the like. The invention has simple structure, accurate counting as well as low cost and is suitable for generalization.

Description

(1) Technical field: [0001] The invention relates to a reading device, in particular to a remote reading device for a capacitive grid, which is mainly used for remote reading of flow meters (such as water meters, gas meters, electric meters and heat meters). (two) background technology: [0002] Among the reading devices, the water meter reading device is typical. The gear-driven pointer counter and the word wheel counter are the most representative of the water meter reading device. It is characterized by intuitive reading and simple structure. The disadvantage is that it needs to read the meter on site and cannot realize remote Transmission requires the participation of a large number of staff, heavy workload and low efficiency. [0003] The electronic remote counter reading encoder patent of Hangzhou Water Meter Co., Ltd. effectively solves the above problems, and its principle is an encoder that uses the photoelectric principle. [0004] The end face of the character wh...
