Problems solved by technology

However, if the meter is read in the form of networking, the meter end needs to send a wake-up packet to the next-level meter end. In this way, the power consumption of the meter end will increase, especially when the meter is read frequently, the battery life of the meter end will be greatly reduced.

Embodiment 1

[0075] Please refer to figure 1 , the present embodiment provides a low-power consumption meter reading method, which is applied to wirelessly acquire metering information collection of water, gas, and heat meters in residents' homes.

[0076] This embodiment takes the home as the unit, and electric meters, water, gas, and heat meters (meter terminals) are arranged in the homes of residents; wireless communication modules, such as GPRS modules, WiFi modules, etc., are configured in the electric meters and the meter terminals to realize the connection between the two. Wireless communication connection. This embodiment adopts the wireless communication meter reading method, which greatly saves resources compared with the existing independent meter reading method of water, gas and heat meters, does not need manual meter reading, and does not need to configure handheld devices, which significantly reduces the cost of meter reading. Since the meter end is powered by the mains, the...

Embodiment 2

[0088] Please refer to figure 2 and image 3 , on the basis of the first embodiment, this embodiment further extends the communication interaction process between the meter end and the meter end in the two-way communication mode, and the similarities will not be repeated here.

[0089] Specifically, after the meter end sends the response data to the meter end, in order to ensure that the control instructions are executed accurately, set the meter end to enter the data receiving state again and maintain the preset duration; so as to receive the data from the meter end again when necessary;

[0090] After receiving the response data, the meter end judges whether to send the data packet to the meter end again according to the execution result of the instruction; if the corresponding execution of the instruction execution result is successful, then no longer sends the data packet to the meter end for execution again; After the preset time has elapsed, the meter will directly ent...

Embodiment 3

[0094] Based on the first and second embodiments, this embodiment further expands and provides a low-power consumption meter reading method, and the similarities will not be repeated here.

[0095] Specifically, the data packet sent from the meter end to the meter end includes CRC check data, which is used by the meter end to verify the integrity of the data packet and ensure the correctness of the data during wireless transmission.

[0096] The meter end communicates with the electric meter end by sending and receiving different frequencies, that is, the sending frequency of the water, gas, and heat meter ends is different from the receiving frequency; the baud rate of the meter end when receiving is different from the baud rate when transmitting, and the transmission is 100Kbps , the reception is 32.768Kbps. This can ensure that the water, gas, and heat meter terminals send data at a higher rate, reducing transmission time and power consumption. When receiving, a lower baud...

Abstract

The invention provides a meter reading method and system with low power consumption. The method comprises the steps of judging that a meter end is in a one-way communication mode or a two-way communication mode; if in the one-way communication mode, actively sending, by the meter end, meter reading data to an electric meter end according to a preset cycle, and entering a dormant state after sending; if in the two-way communication mode, after the meter end actively sends meter reading data to the electric meter end according to the preset cycle, entering a data receiving state, and maintaining a preset time length; and if the meter end does not receive data within the preset time length, entering the dormant state. Different communication modes can be flexibly set according to demands, so that different degrees of power consumption control are realized; besides, fixed data receiving and transmitting time is controlled to furthest realize low power consumption; therefore, the service life of a battery at the meter end is effectively prolonged, and data acquisition at the meter end can be stably and efficiently completed.

Description

technical field [0001] The invention relates to the field of meter reading, in particular to a method and system for reading meters with low power consumption. Background technique [0002] At present, in the field of low-power smart meter reading in China, point-to-point reading or network meter reading is mostly used to collect metering information for meter terminals (water meters, electricity meters, gas meters, and heat meters). [0003] Point-to-read mode, that is, the meter end adopts the carrier monitoring method, and receives the wake-up signal from the handheld device or the concentrator to realize the communication between the meter end and the handheld device, and realize meter reading, switch valve and other functions. This method requires meter reading personnel to go to the scene to carry out hand-held meter reading, which is inefficient; at the same time, due to the carrier monitoring method, the meter end needs to continuously detect the wake-up signal perio...
