Wherein, the standby power supply module 1 is a standby electric energy source of the culture environment controller; the charging module 2 is connected with the control module 4 and the standby power supply module 1 and is used for charging the standby power supply module 1 under the action of the control module 4; the electric quantity detection module 3 is connected with the control module 4 and the standby power supply module 1 and is used for detecting the electric quantity of the standby power supply module 1 under the action of the control module 4; the control module 4 comprises a comparison circuit, the comparison circuit can compare the power supply voltage of the standby power supply module 1 with the power supply voltage converted by the commercial power, and when the power supply voltage converted by the commercial power is smaller than the power supply voltage of the standby power supply module 1, the control module 4 can control the standby power supply module 1 to output electric energy to supply power for the aquaculture environment controller. From this, when commercial power supply takes place to cut off the power supply or when voltage is unusual, stand-by power supply module 1 can come into operation automatically to guarantee that aquaculture environment controller can the continuous operation.
The backup power module 1 may be a rechargeable energy storage element as known in the art. For example, the backup power module 1 may adopt a lithium battery, a lead-acid battery, or a super capacitor, and the like, and those skilled in the art can select the backup power module according to the needs. Generally, the culture environment controller is powered by direct current, the power supply voltage of the culture environment controller can be 12V, 24V or other power supply voltages, and the standby power supply module 1 is a device capable of providing corresponding power supply voltages.
The control module 4 may include a PLC, a single chip microcomputer, and other devices capable of performing logic control.
The charging module 2 includes a first relay 21 and a charging circuit 22. The first relay 21 is connected with the control module 4, and when the first relay 21 is closed under the control of the control module 4, the charging circuit and the standby power supply module 1 form a closed loop to charge the standby power supply module.
The power amount detection module 3 includes a second relay 31, an extra load 32, and a power amount detection circuit 33. Wherein, the second relay 31 is connected with the control module 4, when the second relay 31 is closed under the control of the control module 4, the extra load 32 can form a closed loop with the standby power module 1 through the second relay 31, and at this moment, the voltage output by the standby power module 1 is an effective voltage, which is more accurate than the no-load voltage when the extra load 32 is not connected. The additional load 32 may be a resistor or other type of load. Electric quantity detection circuitry 33 links to each other with control module 4, and when extra load 32 and stand-by power supply module 1 formed closed circuit, electric quantity detection circuitry 33 detected stand-by power supply module 1's output voltage under control module 4's control, and stand-by power supply module 1's output voltage can be used for the electric quantity of characterization stand-by power supply module 1.
In order to avoid the influence of the charging process on the electric quantity detection process, when the electric quantity detection module 3 detects the electric quantity of the standby power supply module 1, the charging module 2 does not charge the standby power supply module 1. Specifically, when detecting the electric quantity, first, the first relay 21 included in the charging module 2 is disconnected under the control of the control module 4, so that the charging circuit 22 and the standby power supply module 1 are disconnected, and then the control module 4 controls the second relay 31 of the electric quantity detection module 3 to be closed, so that the extra load 32 and the standby power supply module 1 form a closed loop, and the electric quantity detection circuit 33 is convenient for detecting the electric quantity.

In order to distinguish the failure of the mains supply from the alarm mode of the standby power supply module 1 with insufficient electric quantity, when the mains supply fails or fails, the alarm module 5 can alarm in the third alarm mode under the control of the control module 4. For example, on the basis of the first alarm mode and the second alarm mode, in the third alarm mode, the alarm module 5 may alarm at a higher frequency and a higher volume, thereby reflecting the severity of the abnormal condition.
Referring to fig. 3, the emergency power supply safeguard device for the cultivation environment controller provided by the present application further includes a wireless communication module 6. The wireless communication module 6 is connected with the control module 4, and when the alarm module 5 sends out an alarm signal, the wireless communication module 6 can send alarm information to the intelligent terminal under the control of the control module 4. The wireless communication module 6 may be a communication element based on mobile wireless communication, satellite communication, internet communication, etc., and the smart terminal may be a terminal device such as a mobile phone. Through setting up wireless communication module 6, when the situation such as power failure, power supply trouble take place for breed environment controller under the mains supply condition, perhaps when stand-by power supply module 1 appears the electric quantity not enough, wireless communication module 6 can send alarm information to intelligent terminal, even make the staff even far away from breeding the cowshed also can in time learn the concrete condition that takes place unusually.
