In this communication method, to complete the meter reading, the address code table corresponding to the meter to be maintained must be stored in the handheld meter reading terminal, which is cumbersome, especially when the meter is replaced, it may be due to the address setting of the meter itself and the hand-held reading. The inconsistency between the addresses stored in the meter terminal leads to missing or even wrong reading, which greatly increases the workload of meter reading personnel, resulting in low meter reading efficiency and high cost

The invention discloses a handheld meter reading terminal, an infrared laser emission head, a testing target surface and an adjusting method. The infrared laser emission head comprises a shell, a visual laser emission part, an infrared laser emission part and an adjusting mechanism, wherein the shell comprises a first accommodating cavity and a second accommodating cavity which are approximately arranged in parallel and an adjusting hole communicated with the second accommodating cavity; the visual laser emission part is arranged in the first accommodating cavity and comprises a visual laser emission tube; the infrared laser emission part is arranged in the second accommodating cavity and comprises an infrared laser emission tube; and the adjusting mechanism is arranged in the adjusting hole and can be pressed against the front end of the infrared laser emission part so as to adjust an angle of the infrared laser emission part, so that infrared laser emitted from the infrared laser emission tube and visual laser emitted from the visual laser emission tube can be aligned at the same object arranged at a set distance. Single-point zero-address communication between the handheld meter reading terminal and an electric meter can be realized, so that the meter reading efficiency is greatly improved, and the meter reading cost is reduced.
Description
technical field [0001] The invention relates to a hand-held meter reading terminal of an electric meter, in particular to a device capable of being used for infrared communication between the hand-held meter reading terminal and the electric meter. Background technique [0002] With the development of electricity consumption by urban and rural residents, the number of electric meters is increasing, and copying electric meter data has become a very important task. An existing meter copying method is to use the infrared transmitter on the handheld meter reading terminal to transmit data packets with addresses to the meter arrays concentrated in the meter box or exposed on the wall. The target meter is judged to match its own coded address Respond accordingly. In this communication method, to complete the meter reading, the address code table corresponding to the meter to be maintained must be stored in the handheld meter reading terminal, which is cumbersome, especially when ...
