Embodiment 1

[0053] Image 6 It is a schematic diagram of the network hierarchical structure model of the automatic frequency hopping test scheme of a single interference source according to Embodiment 1 of the present invention. In this preferred embodiment, as Image 6 The shown two-layer parallel network hierarchy is taken as an example for illustration, and the frequency hopping test scheme for other network hierarchy is basically the same as this process, so it will not be repeated here.

[0054] Test purpose: In the actual field application, when the wireless communication module is working normally, when there is an interference signal of the same frequency or adjacent frequency with the module, the module can read data normally.

[0055] Test steps:

[0056] Step 1: Press Image 6 Set up a network hierarchy model, including a concentrator 62, a terminal communication module 64 (1 block) distributed on the first layer, terminal communication modules 66-70 (3 blocks) on the second ...

Embodiment 2

[0062] Figure 8 It is a schematic diagram of a network hierarchical structure model of an automatic frequency hopping test scheme for multi-network cross-interference according to Embodiment 2 of the present invention. In this preferred embodiment, as Figure 8 The shown two-layer parallel network hierarchy is taken as an example for illustration, and the frequency hopping test scheme for other network hierarchy is basically the same as this process, so it will not be repeated here.

[0063] In actual field applications, when two or more networks are simultaneously networked, the terminal communication module should be able to correctly join the network to which the file belongs, and be able to read data normally.

[0064] Test steps:

[0065] Step 1: Press Figure 8 Set up 2 network hierarchical structure models, including a concentrator 82 distributed in network 1, a terminal communication module 84 (1 block) distributed in the first layer, terminal communication modules 86...

Abstract

The invention discloses a frequency hopping testing method and device. The frequency hopping testing method comprises the steps that a concentrator in a network to be tested and a plurality of wireless communication terminals are arranged in multiple wireless communication shielding boxes respectively according to the hierarchical structure of the network, wherein the wireless communication shielding boxes are connected with one another through attenuators; the wireless communication terminals are networked through the concentrator, and whether networking of the wireless communication terminals is successful or not is tested; under the condition that the networking of the wireless communication terminals is successful, interference signals are transmitted at the current work frequencies of the wireless communication terminals by an interference source, and whether the networking of the wireless communication terminals is successful or not is tested. By the adoption of the frequency hopping testing method and device, the problem that a standardized frequency hopping testing scheme is not provided for the interconnection and interworking networking function of micropower wireless devices in the relevant technology is solved, so that it is guaranteed that the self-healing performance of a communication product passing a frequency hopping test can met the standard level and the normalized level, and a testing means is provided for the interconnection and interworking of products of different manufacturers.

Description

technical field [0001] The invention relates to the communication field, in particular to a frequency hopping test method and device. Background technique [0002] In terms of micro-power wireless detection, domestic and foreign generally only put forward specific detection requirements for the radio frequency indicators of general wireless products, while micro-power wireless interconnection products require corresponding tests for communication protocols, networking functions, etc. At present, domestic In general, only specific testing requirements are put forward for the radio frequency indicators of general wireless products, but no requirements are put forward for the networking function. Therefore, the products of different manufacturers cannot realize interconnection or the application effect of interconnection is poor. [0003] In order to comprehensively improve the technical level and application effect of micro-power wireless devices, the Metrology Center has carr...
