Problems solved by technology

[0003] In the prior art, the remote meter reading technology mostly adopts the ZigBee type short-distance ad hoc network communication mode to form a remote wireless meter reading system. However, because the wireless communication signal has a certain attenuation, the existing remote wireless meter reading system needs The establishment of a large number of relays and gateways leads to the high cost of the existing remote wireless meter reading system, and the complex structure and cumbersome construction lead to many problems in the early setting and later maintenance.

Embodiment 1

[0104] Please refer to figure 1 , Embodiment 1 of the present invention is: a meter reading method, which can improve the probability of successful meter reading by handheld during the mobile meter reading process, and ensure the reliability of the data information obtained, including:

[0105] S101. Acquire a first channel according to a preset first frequency. The first channel is a wireless communication channel, and the frequency of the first channel can be set according to actual conditions.

[0106] S102. The handheld device sends command information for discovering the meter to the meter through the first channel, and the command information includes a signal strength threshold, an ID of the handheld computer, and a broadcast control code. The command information may be a command frame, and the threshold of the signal strength is the RSSI (Received Signal Strength Indication) threshold, which can be set according to actual needs. In this embodiment, the handheld devic...

Embodiment 2

[0112] Please refer to figure 2 , Embodiment 2 of the present invention is a further extension of Embodiment 1, and the similarities will not be repeated. The difference is that before step S102, it also includes:

[0113] S201. Acquire a second channel according to a preset second frequency. The second channel is also a wireless communication channel, and the second frequency is different from the first frequency, which can be set according to specific situations.

[0114] S202. The handheld device sends preamble sequence information through the second channel, where the preamble sequence information includes the ID of the handheld device. By setting two channels, the orderly reply of meters can be realized, occupying less channel resources, and facilitating subsequent centralized meter reading.

[0115] S203. If the meter monitors the preamble sequence information on the second channel, the meter receives the preamble sequence information and records the ID of the handhel...

Embodiment 3

[0137] This embodiment is a specific application scenario of the above embodiment, and is applicable to the scenario where there are pre-stored meter files in the handheld, specifically including:

[0138] The meter reading staff carries the handheld device and drives the car along the preset meter reading route at a speed of 5-10Km / h, and the meter file is pre-stored in the handheld device. When it is judged that there is no other preamble sequence information in the second channel, the preamble sequence information is sent to the surroundings through the second channel, and then the command information for discovering the meter is sent to the meter through the first channel. If the handheld device receives the address information from the meter, it judges whether the signal strength when receiving the address information is greater than a threshold, and if so, records the address information. Then the handheld will judge whether the address information exists in the meter fi...

Abstract

The present invention discloses a meter reading method and a meter reading system. The meter reading method comprises that a first channel is acquired according to a preset first frequency; a handheld device transmits meter discovery command information to a meter through the fist cannel, wherein the command information comprises the threshold value of signal intensity; if the signal intensity of the meter at the command information receiving time is greater than the threshold value, the meter transmits own address information to the handheld device; if the signal intensity of the handheld device at the address information receiving time is greater than the threshold value, the handheld device records the address information; and the handheld device acquires the data information of the meter according to the address information. According to the present invention, by respectively judging whether the signal intensities of the meter and the handheld device at the corresponding information receiving time are greater than the threshold values, the stable and reliable communication link between the meter and the handheld device is formed, such that the successful meter recording probability of the handheld device during the movable meter recording process can be improved, the meter reading efficiency can be improved, and the reliability of the acquired data information can be ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a meter reading method and system thereof. Background technique [0002] The traditional manual meter reading method has many disadvantages, such as high labor intensity, low efficiency, high management cost, and reading errors. With the emergence and development of wireless sensor networks, the application of wireless sensor network technology to meter reading systems has been extensively studied and applied. The use of wireless meter reading can effectively solve the disadvantages of manual meter reading. [0003] In the prior art, the remote meter reading technology mostly adopts the ZigBee type short-distance ad hoc network communication mode to form a remote wireless meter reading system. However, because the wireless communication signal has a certain attenuation, the existing remote wireless meter reading system needs The establishment of a large number of relays an...
