Detailed Description
In order to more clearly explain the overall concept of the present application, the following detailed description is given by way of example in conjunction with the accompanying drawings.
The embodiment of the application discloses a time-delay power-on circuit for nursing communication, as shown in fig. 1, a main power supply circuit 101 is connected with an external distribution box to supply power to the whole medical equipment, a rectification circuit 102 is composed of D1, D2, D3 and D4 diodes, and the medical equipment is ensured to be normally powered on under the condition that the anode and the cathode of the medical equipment are reversely connected.
The current that block terminal output is divided into two the tunnel after total supply circuit 101, rectifier circuit 102, fuse RF and diode D5: one path flows into the singlechip power supply circuit 103, and the other path flows into the MOS circuit 104. After the current flows into the power supply circuit 103 of the single chip microcomputer, the chip with the pin converts the voltage of the current into the working voltage of the single chip microcomputer in the delay control circuit 105. In the singlechip power supply circuit 103, the resistor R6 and the capacitor C3 play a role in stabilizing voltage, and the resistor R5, the capacitor C4 and the capacitor C2 play a role in protecting the singlechip power supply circuit 103.
After the current enters the control circuit 105 to be powered on, the single chip generates the power-on time of the medical equipment according to the following formula:
wherein T represents the power-on time; a1 represents a first dividend; a2 represents the maximum value of the corresponding numerical value of each byte, and A3 represents the maximum power supply time of the power supply equipment. The single chip microcomputer extracts a plurality of bytes from the serial number of the single chip microcomputer and combines the plurality of bytes into a first dividend, for example, if the single chip microcomputer extracts two bytes from the serial number of the single chip microcomputer which are 11111111 and 10000000, respectively, the first dividend may be 1111111110000000 or 1000000011111111111. In the embodiment of the present application, in order to make the power-on time of each time as different as possible, the following rule is formulated to generate the first dividend, taking extracting two bytes as an example: when the power-on time is calculated for the first time, the single chip microcomputer extracts a first byte and a second byte in the serial number, wherein the first byte in the generated first dividend is a high digit, and the second byte is a low digit; when the power-on time is calculated for the second time, the single chip microcomputer extracts the second byte and the third byte in the serial number, the second byte is the high digit, the third byte is the low digit, and so on until the last but one byte and the last byte in the serial number are extracted, the second byte is the high digit, and the last byte is the low digit in the generated first dividend. And when the power-on time is calculated again later, the single chip microcomputer executes the process again.
And the singlechip calculates the maximum value of the numerical value corresponding to each extracted byte according to the number of the bytes of the first dividend. For example, if the first dividend consists of two bytes, then the corresponding A2 is
1111111111111111, namely 65535. The maximum power supply time A3 of the power supply equipment can be set in the single chip microcomputer according to actual conditions. For example, 10 medical devices need to be powered, the maximum power supply time is 1s, if there are 100 medical devices that need to be powered, the maximum power supply time remains unchanged, since A1 is necessarily smaller than A2, which means that 100 medical devices need to be powered within 1s, and the total output power is necessarily increased. If the maximum power supply time is set to 30s, the above formula makes the power-on time of 100 medical devices distributed between 0 and 30s, and theoretically, 100 medical devices can be supplied without increasing the total output power.
In order to better enable the total output power to meet the power consumed when a plurality of medical devices are powered on, in the embodiment of the application, the power-on time range of each medical device is preset. And after the singlechip calculates the power-on time, judging whether the calculated power-on time is in the power-on time range, under the condition that the calculated power-on time is not in the power-on time range, re-extracting bytes to combine into a second dividend according to a formulated rule, and calculating the power-on time until the calculated power-on time is in the power-on time range. For example, the power-on time range of the medical device a is 1 to 10s, if the calculated power-on time is 11s, the single chip microcomputer re-extracts bytes to generate new power-on time, judges whether the calculated power-on time is within 1 to 10s, and repeats the above operations until the generated power-on time is within 1 to 10s. Specifically, the operation and maintenance staff can set the power-on time range of each medical device according to the total output power, so that the total output power is enough to supply power to the plurality of medical devices in the power-on time range. For example, the total output power is at most 10 medical devices at the same time, but now 20 medical devices need to be powered, then the power-on time range of 10 medical devices may be set to (0s, 10s), the power-on time range of another 10 medical devices may be set to (10s, 20s), and then the total output power is sufficient to power 10 medical devices in both (0s, 10s ] and (10s, 20s ], so as to power a plurality of medical devices without increasing the total output power.
As shown in fig. 1, when the current time does not reach the power-on time, the transistor in the delay control circuit 105 is not turned on, the source and the gate of the MOS transistor in the MOS circuit 104 receive the high-level signal sent by the main power supply circuit, and at this time, the MOS transistor cannot be turned on, and therefore cannot supply power to the plurality of circuits to be supplied with power.
When the current time reaches the power-on time, the singlechip starts to supply power, and the triode is in a conducting state;
a source electrode of an MOS tube in the MOS circuit 104 receives a high level signal sent by a main power supply circuit; the grid electrode of the MOS tube receives a level signal sent by the singlechip, and the emitter electrode of the triode is grounded, so that the grid electrode of the MOS tube receives a low level signal; at the moment, the MOS tube can be conducted, so that power can be supplied to a plurality of circuits to be supplied.
In the delay control circuit 105, the first resistor R1 is used for current limiting. The second resistor R2 ensures that the level output by the singlechip does not cause the malfunction of the triode. In the MOS circuit 104, the third resistor R3 is used for current limiting; the voltage stabilizing circuit can maintain the voltage difference between the source electrode and the grid electrode of the MOS tube to ensure the normal work of the MOS tube and consists of a voltage stabilizing diode D6, a resistor R4 and a capacitor C1.
As shown in fig. 1, the input end of the circuit to be powered 106 is connected to the drain of the MOS transistor, so as to control the power-on time of the circuit to be powered 106 by using the MOS circuit 104. The circuit 106 to be powered is composed of capacitors C5, C6, and C7, resistors R7 and R8, an inductor L1, and a diode D7.
