The utility model provides a GSM-based motor remote integrated protection monitor and relates to the improvement of oil field equipment monitoring and protecting means, which is characterized in that a signal sending and receiving port of a single-chip microcomputer of a monitor is connected with a GSM mobile communication network. A three-phase AC power supply is connected with the signal input end of the single-chip microcomputer through a voltage detection circuit power supply. The three-phase AC power supply is connected with a motor through a power-operated circuit breaker, an AC contactor and a motor protector respectively. The power-operated circuit breaker is connected with the signal output end of the single-chip microcomputer through a power supply control circuit. A motor protection circuit is connected with the signal input end of the single-chip microcomputer through an interface circuit. The motor is connected with the signal input end of the single-chip microcomputer through a temperature detection circuit. According to the technical scheme of the utility model, the monitor transmits the operation parameters of the motor to a remote user's handset in the form of a short message through a GSM module in a timing manner. If the power supply or the motor breaks down, the monitor momentarily sends out the fault information. Meanwhile, an operator can momentarily find out the operation state of the motor by means of the handset. The GSM-based motor remote integrated protection monitor is simple in structure, convenient to use, safe and reliable.
