Embodiment Construction
[0018] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.
[0019] figure 1 A system block diagram of a mobile POS wireless performance mass production test method provided by the present invention, such as figure 1 As shown, the shielding box is used to prevent external electromagnetic radiation from entering the shielding box, and at the same time restrict the electromagnetic radiation of the test equipment in the shielding box from going out of the box, creating a clean test environment.
[0020] First, set up a test environment. Randomly select the same batch of 10 mobile POS to test the TRP (Total Radiated Power) and TIS (Total Itropic Sensitivity) values of each POS in the low, middle and high channels of GSM900MHz in the 3D darkroom with the probe test system, and pass these two values To judge the performance of POS in terms of transmitting power and receiving sensitivity, and ...

The invention provides a method for testing wireless performance of mobile POS (point of sale) machines in a large scale. Firstly a flat coupled antenna position and a mobile POS placing position in a shielding box are determined by virtue of a contrast test with a 3D darkroom; then a radio frequency general-purpose tester is connected with the flat coupled antenna in the shielding box by virtue of a radio frequency connecting wire, and the mobile POS machine to be tested is placed on the flat coupled antenna; and then the radio frequency general-purpose tester is connected with a PC (personal computer) installed with auxiliary test software by virtue of a data acquisition card; and the shielding box is driven to close a cover by virtue of an air pump, the auxiliary test software and the mobile POS machine to be tested are connected and operated, the radio frequency general-purpose tester tests each test item checked by the auxiliary test software, and the software can give an alarm once the test item which does not meet the index set in advance appears. The method provided by the invention overcomes the defects of the prior art, is uniform in test environment and accurate and visual in test result and improves production efficiency and product consistency.
Description
technical field [0001] The invention relates to a mobile POS wireless performance mass production test method, which belongs to the technical field of mobile POS. Background technique [0002] With the development of the mobile Internet, people have higher and higher requirements for mobile payment, and the demand for mobile POS is also increasing. The existing mobile POS test method is to test the communication capability of uploading and downloading data by obtaining an IP from a mobile base station through the mobile POS. This method is affected by many external factors such as weather conditions and community congestion during the test. There are defects such as inconsistent test standards, inconsistent time required, and inability to have an indicative description of the specific performance of the machine. There are many constraints on the consistency and productivity of mobile POS production. Contents of the invention [0003] The technical problem to be solved b...
