Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated。Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention。
In order to technical solutions according to the invention are described, illustrate below by specific embodiment。
Embodiment one:
Fig. 1, it is shown that the flow chart of the method being common to various module power-on and power-off that the embodiment of the present invention one provides, specifically comprising the following steps that of the method
The power on signal foot level of the module that powers on down for low level, and is remained low level by step S101, device systems, makes described module power on。
Fig. 2, it is shown that the flow chart of module powering method in the embodiment of the present invention one, specifically comprises the following steps that
Step S201, device power；
Step S202, inserting and power on module, device systems identifies this module power on signal foot level automatically；
The power on signal foot level of the module that powers on is dragged down by step S203, device systems；
Step S204, differentiating whether the power on signal foot level of module of powering on is continuously low level, if the low level of being continuously, perform step S205, otherwise described module powers on unsuccessfully, performs step S203；
Step S205, module power on successfully。
In the embodiment of the present invention, equipment, for having one or more extendible communication or the network equipment, supports the plug of different manufacturers multimode, and the communication of compatible vendor module and procotol。Wherein device systems is the hardware and software platform that a holding equipment is properly functioning。The hardware product that wherein module provides for each producer, includes but not limited to board。
The power on signal foot level of module is all defined by equipment CPU, and original state is high-impedance state, and device systems all can the low and high level of identification module automatically。When the power on signal foot level of module is pulled low and is continuously low level, module powers on after successfully, and this module level remains low level。Low level interval is (0v-0.8v), and the interval of high level is (2.8v-3.3v)。
Owing to the module of each producer is when powering on, the low level time required is different, such as the low duration of G610 module (wide and logical) power on signal foot is 800ms, the low duration of 52i module (Siemens) power on signal foot is 100ms, in the low duration of emerging 8332 module power on signal feet be 2.5s-4s。In order to reduce the workload of programmer, reduce writing of code, guarantee that different vendor module can power on successfully, the power on signal foot level of the module that powers on is dragged down by device systems unification in embodiments of the present invention, this module power on signal foot level is made to meet low level requirement, it is achieved module powers on successfully。User can input " AT " instruction then carriage return on device systems, and screen shows " OK ", checks whether module powers on successful。
Step S102, identification lower electricity module, the lower signal of telecommunication foot low level of lower electricity module is drawn high by device systems, then adopts AT instruction to shut down, electricity under module。
Fig. 3, it is shown that the flow chart of method for electrically under module in the embodiment of the present invention one, specifically comprises the following steps that
Step S301, in device systems input " AT+CGMM " instruction obtain lower electricity module id；
The lower signal of telecommunication foot low level obtaining the lower electricity module of mark is drawn high by step S302, device systems；
Step S303, according to this module type, in device systems input AT dependent instruction this module is closed；
Whether step S304, the lower signal of telecommunication foot level differentiating this module are high level, if for high level, perform step S306, otherwise perform step S305；
Step S305, module are restarted；
Step S306, module power-off。
In the embodiment of the present invention, in lower electric process, programmer can input " AT+CGMM " instruction on device systems and obtain lower electricity module id, signal of telecommunication foot low level under the lower electricity module identified is drawn high, reach high level region, further according to this module type, adopt AT instruction that this module is shut down, if the lower signal of telecommunication foot level of lower electricity module maintains low level, then adopt AT shutdown command that module can be made to restart。If electricity under module powered-off fault, it will have the persistent period 5 seconds, meet various module and carry out data storage, it is ensured that data safety and module life。
Such as, under G610 module (wide and logical), the low duration of signal of telecommunication foot is 3s, under 52i module (Siemens), the low duration of signal of telecommunication foot is 10ms, in under emerging 8332 modules the low duration of signal of telecommunication foot be 2s, due to each vendor module traditional approach be all meet under respective lower signal of telecommunication foot low-voltage carries out electrically operated, so cause the electricity persistent period under each module inconsistent, the AT instruction of part of module shutdown is different, programmer needs to increase new instruction shutdown, and need on-hook to verify, and in processing procedure, cause and automatically restart again after electricity under part of module。And in the embodiment of the present invention, the lower signal of telecommunication foot low level of lower electricity module is drawn high by device systems, solves the electricity persistent period under each module inconsistent, the problem automatically restarted again after electricity under part of module, and ensure that the safety of module data, extend module service life。
