Problems solved by technology

[0003] However, in practical applications, within the power range allowed by the country, the Zigbee method is difficult to meet the automatic networking needs of different households due to its high transmission frequency and large transmission bandwidth.
For this reason, a wireless transmission method with a transmission frequency of 470M is gradually being used in the field of wireless meter reading and central heating household metering. , will often reduce its transmission band, for example, setting it to 9600bps or even lower, which will inevitably lead to a decrease in its ad hoc network speed and data transmission speed, and it is even difficult to guarantee the actual time requirement
Although some typical wireless ad hoc network protocols, such as LEACH routing protocol, etc., consider the mechanism of hierarchical routing and data fusion, it is still difficult to meet the actual needs in the face of low transmission bandwidth.

Embodiment 1

[0042] like figure 2 As shown, the wireless temperature acquisition device for household metering of central heating in the present invention mainly includes a central server, a building coordinator, a collection node and a mobile deployment terminal; The deployment information, collect the temperature information of each collection node; The building coordinator is responsible for collecting the temperature data of each collection node under its jurisdiction, and upload to the central server; The collection node is responsible for collecting the real-time temperature data of the households where it is located ; The mobile deployment terminal is responsible for reporting the deployment information of each building coordinator and collection node to the central server; wherein the central server and each building coordinator are interconnected by GPRS, and the central server and each mobile deployment terminal are connected by GPRS / 3G interconnection, the building coordinator...

Embodiment 2

[0044] combine figure 1 and image 3 , describing the device deployment process of the preferred embodiment 2 of the present invention:

[0045] Step (a1): Set the number of units U of the building to be deployed, the number of floors F, and the maximum number of households H of the specified floor of the specified unit and other related building information.

[0046] Step (a2): The first step is to deploy the building coordinator. like image 3 As shown, the building coordinator C1 is installed at the (u, f, h) position, that is, unit u, floor f, adjacent to household h, where u=1, f=1, h=1; The deployment information of the building coordinator C1 is uploaded to the server, and its deployment information includes the building, unit, floor, the nearest house number, and the range of units under the jurisdiction of the coordinator u min .. u max and jurisdiction floor range f Bottom .. f Top ; The second step is to deploy the collection nodes. Install the collection no...

Embodiment 3

[0048] combine figure 1 and image 3 , describing the wireless signal penetration testing process of the preferred embodiment 3 of the present invention:

[0049] Step (a3): Carry out the mensuration of signal penetration TC by building coordinator, in image 3 In the deployment example shown, the building coordinator C1 conducts connectivity tests on the A[u, f+j, h] collection nodes respectively, and the value of j ranges from 0 to f Top -f, until the collection nodes from building coordinator C1 to A[u,f+j,h] are disconnected or the value of j is f Top -f, so that the signal penetration TC can be calculated according to formula (1), and α in formula (1) can generally be set to 0.8. For deployment implementation examples image 3 Among them, the obtained TC is 3, which means that the wireless signal can penetrate 3 floors.

[0050]

[0051] The test of the connectivity between two nodes is that the source node sends a test packet to the target node. If the source node ...

Abstract

The invention belongs to the technical field of building heating measurement and control, and particularly relates to a wireless manner-based temperature acquisition method facing central heating household measurement and an apparatus thereof. The method comprises: parameter setting and system deployment, signal penetration strength measurement, stem route establishment, branch route establishment, branch route node character setting, distribution and testing on nodes in clusters, temperature acquisition in clusters, temperature data reporting and other steps. According to the present invention, the floor priority sub-flooring route networking method combined with the collection node position information is provided to increase a networking speed under a low speed environment; and the temperature acquisition and upload mechanism adopting the cluster as the unit is provided, and the temperature difference data and bitmap identification combined method is introduced so as to effectively reduce the amount of transmission data, such that reliability and efficiency of data transmission are increased.

Description

technical field [0001] The invention belongs to the technical field of building heating measurement and control, and in particular relates to a wireless-based temperature acquisition method and a device thereof for household metering of central heating. Background technique [0002] With the continuous increase of building area in our country, the demand for heating application is also expanding, so the research and improvement of heating control system is very urgent. The traditional household metering method of central heating adopts the area allocation method, that is, a heat meter is installed in the entire building to collect the heat consumption of the entire building, and on this basis, it is allocated to each household according to the area. However, due to the location of each household , The orientation is different, although each household pays according to the unified standard, but enjoys different indoor temperatures, that is, the phenomenon of "equal cost but u...
