Gas wireless meter reading system

Abstract

The invention discloses a gas wireless meter reading system which comprises direct reading wireless meters and a counting and acquisition device, wherein the direct reading wireless meters are used for acquiring counting data of gas and transmitting the counting data to the counting and acquisition device in a wireless manner; the counting and acquisition device is used for acquiring the counting data; the direct reading wireless meters are wirelessly connected with the counting and acquisition device; the number of the direct reading wireless meters are at least two; all the direct reading wireless meters are connected with one another in a wireless manner; and the direct reading wireless meters are also used for receiving the counting data acquired by the adjacent direct reading wireless meters and transmitting the counting data to the counting and acquisition device in a wireless manner. In the gas wireless meter reading system, the direct reading wireless meters are used for acquiring the counting data of the gas and transmitting the counting data to the counting and acquisition device in a wireless manner; the direct reading wireless meters can be automatically networked in the system, so that the reliable transmission of multi-level data is achieved through more than one pair of data transmission, and the reliability of the system is improved; and moreover, the wiring is not required when the data is transmitted in a wireless manner, so that the installation construction and the system maintenance are simple.

Description

technical field [0001] The invention relates to the technical field of electronic instruments, in particular to a gas wireless meter reading system. Background technique [0002] The problem of energy meter data copying has become an urgent and unresolved problem in the energy supply sector. In the process of industry informatization, automatic copying of energy meter data is of great significance, because energy meter data is the most primitive data in the sales process of the energy sector, and the accuracy and timeliness of this data directly affects other informationization levels within the industry. [0003] The traditional manual meter reading is time-consuming and labor-intensive, and the accuracy and timeliness cannot be reliably guaranteed. Although the traditional remote meter reading system (ie pulse remote transmission, pulse wireless and direct reading remote transmission) can overcome the above local problems, But there are also the following disadvantages: ...

Problems solved by technology

[0003] Traditional manual meter reading is time-consuming and laborious, and the accuracy and timeliness cannot be reliably guaranteed. Although the traditional remote meter reading system (that is, pulse remote transmission, pulse wireless and direct reading remote transmission) can overcome the above partial problems, But there are also the following disadvantages:

[0004] 1. Pulse remote transmission (pulse metering + wired transmission) system, the system must be permanently powered, if the power is cut off, the system will underestimate the phenomenon, because the system needs long-term power supply, resulting in waste of power resources, and pulse remote transmission + wired transmission The wiring construction intensity of the method is high, and the system maintenance is difficult

[0005] 2. Pulse wireless (that is, pulse metering + wireless transmission) system, the meter adopts pulse cumulative metering, the battery must be permanently powered, and the system cannot work for a long time; and the wireless transmission of the system uses ordinary one-way or two-way point-to-point radio frequency modules, which are subject to Influenced by the environment of the installation site, the success rate of this type of wireless transmission is low, and the stability is low

[0006] 3. Direct-reading remote transmission (that is, direct-reading measurement + wired transmission) system, because the system uses wired transmission, its wiring construction intensity is high, and it is difficult to check after the system line fails, and when the old city is renovated or other old meters are replaced, cannot use the system

[0007] It can be seen that the above-mentioned meter reading systems have difficulties such as inaccurate data, large amount of maintenance, and difficult construction, which lead to the inability to better realize energy information management.
