Embodiment Construction
[0008] The present invention will be further described below in conjunction with the accompanying drawings, and the present invention is relatively clear to those skilled in the art.
[0009] See attached figure 1 , according to attached figure 1 Connect each module circuit as shown, among which the GPRS / CDMA / 3G module is connected to the frequency converter through the I / O port to control the operation of the frequency converter, and is also connected to obtain the running status data of the frequency converter through the I / O port and When the frequency converter is connected, isolation and drive circuits need to be added. A watchdog module is added to this circuit design. The watchdog module circuit is connected to the RESET pin of the GPRS / CDMA / 3G module and an IO port to detect the operation of the device and improve the stable and reliable operation of the device.
[0010] See attached figure 2 , The work flow of the inverter control program integrated in the GPRS / CD...

The invention relates to the technical field of wireless communication, in particular to a remote wireless monitoring device integrated with control function of a frequency converter, which comprises a GPRS / CDMA / 3G module, the frequency converter, a watchdog module, an antenna, an SIM card and a device power supply module, wherein the frequency converter is integrated in the GPRS / CDMA / 3G module through an I / O port to control the operation of the frequency converter, and the GPRS / CDMA / 3G module is also connected with a peripheral circuit mainly comprising a watchdog circuit, an SIM card circuit and a device power supply circuit; and the GPRS / CDMA / 3G module is connected with a remote control center through wireless communication. Compared with the prior art, the remote wireless monitoring device saves a PLC or MCU control unit, the GPRS / CDMA / 3G module communicates with the remote control center to achieve the function of monitoring the frequency converter, and the watchdog module is added so that the integration level of the device is high, the power consumption is reduced and the stability and the reliability of the system running are improved.
Description
[technical field] [0001] The invention relates to the technical field of wireless communication, in particular to a remote wireless monitoring device with integrated frequency converter control functions. [Background technique] [0002] At present, the control of the frequency converter is mainly realized by adding a PLC or MCU control unit, and the communication function and the control function are independent of each other. The problems brought about are high product cost, high power consumption, and affected reliability and stability. [Content of the invention] [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and form a new monitoring device with remote communication function by integrating the control function of the frequency converter in the GPRS / CDMA / 3G module. [0004] In order to achieve the above purpose, a remote wireless monitoring device with integrated frequency converter control function is designed, including ...
