On the detection body of the object, a detection point is formed, such as three detection points on the building A. The thermal inspection node device is configured to detect the outer surface temperature, the inner surface temperature, and the heat flow density information on the inner surface, which may be composed of an outdoor detecting node and an indoor detecting node. The outdoor detection node is uniformly placed on the outer surface of the detection body by a 4-way temperature sensor to realize the collection of 4 external surface temperature information. Since the building is in a sealed state during the inspection, the outdoor detection node is powered by a battery. The indoor detection node is composed of a 4-way temperature sensor and a 4-way heat flow density sensor. The arrangement position of the 4-way temperature sensor of the indoor detection node corresponds to the layout position of the 4-way temperature sensor on the outdoor detection node.

The integrated inspection instrument periodically receives the data of each thermal inspection node device and parses it into the thermal calculation available data, and responds to the energy-saving detection analysis software timing query command on the remote server to upload all the thermal data. The integrated inspection instrument can support 32 detection nodes (ie, thermal inspection node equipment), 384 channels of data; because each thermal inspection node device needs to detect 4 external surface temperatures, 4 internal surface temperatures, and 4 heat flux data. The integrated inspection instrument also has functions such as network self-diagnosis, data recovery function and data abnormal alarm.

As shown in Fig. 2, a flow chart of a one-time rapid detection and evaluation method for the building heat consumption of the building group of the present invention is given, which can be realized by the following steps:

a) Determine the building to be inspected and the main body of the test, in accordance with the current building energy-saving test mark in the relevant country The quasi-and-design rule specifies one or more buildings to be inspected located in the same area, and multiple detection points may be selected on each building;

F-4). The time window length is determined, the remote server determines whether the number of collected data records has reached t/T2, if t/T2 is reached, step f-5) is performed; if not, step f is performed -2);

F-5). Whether the temperature difference between the inner and outer surfaces meets the condition, the remote server judges whether the difference between the inner surface and the outer surface temperature is at least 10 °C in the reverse order of the data collection order; If the record data satisfying the width of the time window is satisfied, step f-6) is performed; if each piece of data satisfies the time window width condition, step f-7) is performed _;

F_6). Obtain t/T2 data from the new starting point, and set the recording data that does not satisfy the difference between the inner surface and the outer surface temperature to be at least 10 °C in the chronological order as the nth, then record the n+1 as the time window. Starting point, performing step f-2), obtaining t/T2 data;

F_7). The difference between the calculated values of the thermal resistance should be less than or equal to 5%. For the detection data in the time window, determine whether the difference between the calculated thermal resistance value and the calculated thermal resistance value before 24 hours satisfies the condition of 5% or less. If the condition is met, it indicates that the data in the t time period is available data; if the condition is not met, step f-8) is performed _;

F-8). Obtain the t/T2 data from the new starting point, and set the recording data that does not satisfy the difference between the calculated thermal resistance value and the calculated thermal resistance value before 24 hours, which is 5% or less, in the chronological order, the mth m+1 The strip record is the start point of the time window, and step f-2) is executed to obtain t/T2 data.
