step 1, installing a counting wheel set (2) in a shell (13) of a counter bracket (1), wherein magnetic steel is arranged on a character wheel (21);
step 2. Firstly, a Hall sensor (3) is welded on a sampling plate I (61) and a sampling plate II (62), and then the sampling plate I (61) and the sampling plate II (62) are respectively and fixedly arranged on two sides of a shell (13), specifically: the sampling plate I (61) is arranged in a groove (16) on the shell (13), the sampling plate II (62) is arranged on one side wall of the shell (13) opposite to the side wall of the groove (16), the Hall sensors (3) on the sampling plate I (61) and the sampling plate II (62) are inserted into the groove body (12) and are close to the character wheel (21), and an included angle is formed between the Hall sensors (3) on the sampling plate I (61) and the Hall sensors (3) on the sampling plate II (62);
step 3, connecting a power VCC pin on a sampling plate I (61) with a power VCC pin on a sampling plate II (62) through a 66 polyvinyl chloride insulating black wire, and connecting a grounding GND pin on the sampling plate I (61) with a grounding GND pin on the sampling plate II (62) through the 66 polyvinyl chloride insulating black wire;
step 4, an input/output interface of the counter is composed of a 4P low-frequency connector, namely a sampling plate I (61) and a sampling plate II (62) are connected with a control module through a 4P low-frequency connecting wire, one end of the 4P low-frequency connecting wire is connected with a Hall sensor (3), and the other end of the 4P low-frequency connecting wire is connected with the control module;
and 5. The gas meter ventilates and drives the driving wheel (22) to rotate, the driving wheel (22) drives the character wheel (21) to rotate and meter, when the embedded magnetic steel on the character wheel (21) rotates to the action range of the Hall sensor (3) on the sampling plate I (61) and the sampling plate II (62), the Hall sensor (3) has a high level to be changed into a low level, a pulse signal is formed, and the pulse signal is transmitted to the control module through the output port of the 4P low-frequency connector to finish sampling.
