Background technology
The detection of the existing remote communication module 10 for state net I type concentrator, is all placed on concentrator and detects, as shown in Figure 1.When detecting remote communication module, first power on to concentrator, then concentrator carries out system initialization, just can start shooting to remote communication module after this process completes, and then carries out dialling, connecting the operations such as main website.The whole testing process of remote communication module on average needs 2 ~ 3 minutes, even if failure is detected in midway, also cannot know the failure where failed, what reason causes fast.Therefore, concentrator detects not only length consuming time to remote communication module, and efficiency is low.
Utility model content
The technical problems to be solved in the utility model on concentrator, detects length consuming time, inefficient defect in order to overcoming prior art to remote communication module, provides a kind of detection system of short, remote communication module that detection efficiency is high consuming time.
The utility model solves above-mentioned technical matters by following technical proposals:
A kind of detection system of remote communication module, its feature is, it comprises a pick-up unit and a host computer, this pick-up unit is provided with one for placing draw-in groove and a serial ports of remote communication module, this pick-up unit comprises an on/off circuit, one SIM card (client identification module) circuit, one radio circuit, one serial interface switching circuit and a power circuit, this on/off circuit, this SIM card circuit, this radio circuit and this serial interface switching circuit are all electrically connected with this draw-in groove, this power circuit is to this on/off circuit, this SIM card circuit, this radio circuit and this serial interface switching circuit are powered, this serial interface switching circuit is used for Transistor-Transistor Logic level (transistor-transistor logic level) signal to be converted to RS232 (asynchronous transmission standard interface) level signal, the output terminal of this serial interface switching circuit is electrically connected with this host computer by this serial ports.
In this programme, remote communication module for state's net I type concentrator is directly inserted in draw-in groove, and the switching on and shutting down signal of remote communication module, SIM card signal, radiofrequency signal and output signal are electrically connected with the on/off circuit on pick-up unit, SIM card circuit, radio circuit and serial interface switching circuit respectively.The output signal of remote communication module is Transistor-Transistor Logic level signal, this Transistor-Transistor Logic level signal is converted to RS232 level signal by serial interface switching circuit, and be electrically connected with host computer by serial ports, utilize the testing software in host computer to test this RS232 level signal, thus realize testing remote communication module.Wherein, this host computer is provided with the interface corresponding with the serial ports of this pick-up unit.
Preferably, this serial ports turns USB (USB (universal serial bus)) interface line by RS232 and is electrically connected with this host computer.Host computer is provided with USB interface, turns usb line be connected with host computer by the pick-up unit being inserted with remote communication module by RS232.
Preferably, this host computer is PC (personal computer).Because PC is provided with serial ports and USB interface, therefore, pick-up unit both directly can be connected with PC by serial ports, also can turn usb line by RS232 and be connected with PC.
Positive progressive effect of the present utility model is: compared with existing test of netting the remote communication module of I type concentrator for state, the detection system structure of the utility model remote communication module is simple, when remote communication module is detected consuming time less, efficiency is high, especially very convenient when test in early stage and subsequent maintenance.
Accompanying drawing explanation
Fig. 1 is the structured flowchart that prior art China net I type concentrator detects remote communication module.
Fig. 2 is the structured flowchart of the detection system of the remote communication module of the utility model embodiment.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
A detection system for remote communication module, as shown in Figure 2, it comprises pick-up unit 21 and PC 22, and pick-up unit 21 is provided with draw-in groove 23 and serial ports 24, and draw-in groove 23 is for placing remote communication module 10, and serial ports 24 is for being electrically connected with PC 22.
Pick-up unit 21 comprises on/off circuit 25, SIM card circuit 26, radio circuit 27, serial interface switching circuit 28 and power circuit 29, on/off circuit 25, SIM card circuit 26, radio circuit 27 and serial interface switching circuit 28 are all electrically connected with draw-in groove 23, power circuit 29 is to on/off circuit 25, SIM card circuit 26, radio circuit 27 and serial interface switching circuit 28 are powered, serial interface switching circuit 28 is converted to RS232 level signal for Transistor-Transistor Logic level signal remote communication module 10 exported, the output terminal of serial interface switching circuit 28 is directly electrically connected with PC 22 by serial ports 24, or turn usb line by serial ports and RS232 and be electrically connected with PC 22.
When being inserted on draw-in groove for the remote communication module of state's net I type concentrator, the switching on and shutting down signal of remote communication module, SIM card signal, radiofrequency signal and output signal are electrically connected with the on/off circuit on pick-up unit, SIM card circuit, radio circuit and serial interface switching circuit respectively.The Transistor-Transistor Logic level signal that remote communication module exports by serial interface switching circuit is converted to RS232 level signal, and the RS232 level signal be converted to is sent to PC by serial ports by pick-up unit.The testing software of the remote communication module for state net I type concentrator has been installed in PC.Through experiment, the average detected time dimension for the remote communication module of state net I type concentrator is held in about 1 minute, drastically increases production testing efficiency.In addition, the pick-up unit in the utility model is all very helpful to the test in early stage of product and subsequent maintenance.
