The fire pump shall be manually started once a month, and the power supply situation shall be checked. 2. The fire pump shall be automatically started once a week under the conditions of simulating the automatic control of the fire pump, and the automatic inspection situation shall be automatically recorded and detected and recorded monthly. 3. The battery power of the diesel fire pump shall be detected daily, the oil storage volume of the fuel tank shall be checked weekly, and the diesel fire pump shall be manually started once a month. 4.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following specific examples illustrate the embodiments of the present invention. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0021] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Although only the components related to the present invention are shown in the drawings, they are not drawn according to the number, shape and size of the components in actual implementation. The type, quantity and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0022] Embodiment:

[0023] A flow pressure test and test water system for a fire pump based on the Internet of Things, refer to the attached Figure 1 and the attached Figure 2As shown in the figure, it includes a system main body A, a connecting pipe 9, and a system control electric valve 4 connected to the main fire water supply pipe 11. The connecting pipe 9 is connected to the main fire water supply pipe 11 and is located at the upstream end of the system control electric valve 4. The system main body A includes a water inlet pipe 10, a water outlet pipe 7, and a first branch pipe 12 and a second branch pipe 13 connected in parallel between the water inlet pipe 10 and the water outlet pipe 7. The water outlet pipe 7 is communicated with the fire pool. The system main body A is connected to the connecting pipe 9 through the water inlet pipe 10. A remote pressure gauge 6, a flow test electric valve 3, and an electromagnetic flowmeter 5 are respectively connected to the first branch pipe 12. A test water electric valve 2 is connected to the second branch pipe 13. The remote pressure gauge 6, the flow test electric valve 3, the electromagnetic flowmeter 5, the test water electric valve 2, and the system control electric valve 4 are electrically connected to a single-chip microcomputer, and the single-chip microcomputer is electrically connected to a power supply module for supplying power to it. The single-chip microcomputer is electrically connected to a communication module, and the single-chip microcomputer is wirelessly or wiredly connected to a host computer through the communication module.

[0024] In the specific working process of the present invention, when a water test of the fire pump 8 is required, the system control electric valve 4 is controlled to close through the host computer, and at the same time, the test water electric valve 2 is opened or closed to control the on-off of the water flow, so as to realize automatic or remote control of the water test operation and test the automatic start performance of the fire pump 8. Further, when testing the water flow pressure and water flow of the fire pump 8, the flow test electric valve 3 is controlled to open, the water flow flows through the first branch pipe 12, and the pressure data of the remote pressure gauge 6 and the flow data of the electromagnetic flowmeter 5 are converted into electrical signals and then transmitted to the single-chip microcomputer. The single-chip microcomputer processes and analyzes the electrical signals, and transmits the collected flow and pressure data to the host computer in the fire control room through the communication module. The test data can be observed in real time through the host computer. Relevant personnel can intuitively understand the pressure and flow conditions of the system. It should be noted that the host computer can also be a mobile device such as a mobile phone or a tablet computer. Through the built-in APP, the staff can test the data in real time on the mobile device.

[0025] Preferably, the single-chip microcomputer is also electrically connected to an alarm module. The single-chip microcomputer can compare the collected pressure and flow data with preset standard values to judge whether the fire pump system is in a normal working state. If the data is abnormal, the single-chip microcomputer controls the alarm module to send an alarm signal and transmits the alarm signal to the host computer to prompt possible faults or problems. It should be noted that during the test process, the water flow can directly flow back to the fire pool through the water outlet pipe 7, thereby forming a test water flow cycle.

[0026] Furthermore, a protective cover can be provided outside the system main body A. The protective cover can protect the components of the entire system main body and prevent external forces from damaging the system device. At the same time, the appearance of the protective cover is set to red to serve as a warning. A touch display screen electrically connected to the single-chip microcomputer can also be provided on the surface of the protective cover. The flow and pressure data collected by the upper computer can be synchronously displayed on the display screen after being processed by the signal processing module, so that relevant personnel can also intuitively understand the pressure and flow conditions of the system through the display screen.

[0027] A maintenance valve 1 is provided on the water inlet pipe 10 of the system main body A. The water inlet pipe 10 is connected to the connecting pipe 9 through the maintenance valve 1. The maintenance valve 1 can be kept in an open state all the time. When the system main body A fails or needs to be maintained, the entire system main body A can be removed from the maintenance valve 1, which is convenient for the maintenance of the system main body A.

[0028] In the above-mentioned embodiment, preferably, the test water electric valve 2 is a DN65 test water electric valve. The test water electric valve 2, the flow test electric valve 3, and the system control electric valve 4 have a manual opening function. This ensures that the above valves can still be manually opened or closed manually when the system fails.

[0029] In summary, in the present invention, the system control electric valve 4 and the connecting pipe 9 are connected to the fire main outlet pipe 11, and a pipe network composed of the water inlet pipe 10, the water outlet pipe 7, and the first branch pipe 12 and the second branch pipe 13 connected in parallel between the water inlet pipe 10 and the water outlet pipe 7 is connected to the connecting pipe 9. Finally, a remote pressure gauge 6, a flow test electric valve 3, and an electromagnetic flowmeter 5 are respectively connected to the first branch pipe 12, and a test water electric valve 2 is connected to the second branch pipe 13. By controlling the on-off of the water flow through the electric valve, the automatic start, water flow pressure, and water flow of the fire pump 8 are detected, and the daily maintenance management requirements of remote flow and pressure testing and test water testing are realized, which simplifies the routine inspection and maintenance of the fire pump. It not only overcomes the problem of time-consuming and laborious on-site inspection records and manual operations for the daily maintenance and inspection of the fire pump, but also improves the safety and guarantee degree of the normal operation of the fire protection system.

[0030] The above-mentioned embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
